Happy studying and GOOD LUCK! -Kim About this Guide This guide is simply a compilation of information copied and pasted directly from the NASM textbook, along with some supplementary information I found helpful for my understanding of the material. This guide is not recognized by NASM in any way. Use at your own risk. The guide is organized by chapter, like the textbook. At the beginning of each chapter is a list of the topics NASM called out as particularly important in their test prep guide (found in the online e-learning materials). Some charts and images were scanned directly from the textbook. Others (such as the 3 planes of motion image) were found online. Color coding and highlighting is for visual learning purposes. You’re welcome to make changes to the guide for your own use, but please do not publically distribute a modified version that originated from this guide. This guide might include phrasing and extra details that helped me solidify my personal understanding of the content, but that don’t make sense to you. In those cases, always default to the textbook’s explanations and refer back to it as necessary. Please do not use this guide as your only study tool! There might be questions on the test that aren’t covered here. This is just a compilation of the topics and terms that stood out to me. NASM Study Guide - fittinpretty.com 2 Chapter 1 What to Know: Introduction to Integrated Training Be familiar with all definitions throughout the chapter Optimum Performance Training™ Model o Phase 1: Stabilization Endurance Training o Phase 2: Strength Endurance Training o Phase 3: Hypertrophy Training o Phase 4: Maximal Strength Training o Phase 5: Power Training Escalation of obesity, diabetes, and chronic disease increased demand for personal training First fitness programs (1970’s) didn’t take into account new clients’ medical conditions, training risk factors, muscle imbalances, and goals—they just mimicked fitness professionals’ own programs. Chronic disease: incurable illness or health condition that persists for 1 yr+, resulting in functional limitations and the need for ongoing medical care. Obesity: BMI of 30 or greater, or at least 30 pounds overweight for their height. Overweight: BMI of 25-29.9, or between 25 to 30 pounds overweight for their height. BMI = 703 x (weight in pounds / height^2 in inches) Diabetes: condition in which blood glucose (or blood sugar) is unable to enter cells, resulting in hyperglycemia (high blood sugar). Type 1: Pancreas doesn’t produce insulin Type 2: There’s enough insulin, but cells are resistant ad do not allow insulin to bring adequate amounts of blood sugar into cells Deconditioned: a state of lost physical fitness, which may include muscle imbalances, decreased flexibility, and a lack of core and joint stability. Proprioception: The cumulative sensory input to the central nervous system from all mechanoreceptors that sense body position and limb movement. NASM Study Guide - fittinpretty.com 3 Training the body’s proprioceptive abilities improves balance, coordination, and posture. Past injuries can alter clients’ proprioceptive abilities. Proprioceptively Enriched Environment: An unstable, yet controllable, physical situation in which exercises are performed that cause the body to use its internal balance and stabilization mechanisms. Examples: stability ball dumbbell chest press or single-leg squat vs. bench press or barbell squat OPT model – Optimum Performance Training Model, which takes into account each individual’s goals, needs, and abilities in a safe and systematic fashion. This model was conceptualized for a society that has more structural imbalances and susceptibility to injury than ever before. It can systematically progress any client to any goal. The OPT model includes 3 LEVELS of training: stabilization, strength, and power. Each level includes one or more phases. The 5 PHASES of training: PHASE (1) Stabilization Endurance Training (2) Strength Endurance Training (3) Hypertrophy Training GOAL DETAILS TRAINING STRATEGIES --Increase client’s ability to stabilize joints and maintain optimal posture --Increase muscular endurance while developing optimal neuromuscular efficiency (coordination) Neuromuscular efficiency relies on the appropriate combination of proper alignment (posture) and the stabilization needed to maintain that alignment --Proprioceptively challenging environment (stability) --Low loads, high repetitions Improves: stabilization endurance, prime mover strength, overall work capacity, joint stabilization, and lean body mass --Moderate loads and repetitions (8-12) --Perform two exercises in a superset sequence (back-to-back without rest): one traditional strength exercise in a stable environment (ie bench press) and one stabilization exercise in a less stable (but still controlled) environment (ie stability ball push-up) --High volume, moderate to high loads --Moderate or low repetitions (612) --Maintain stabilization endurance while increasing prime mover strength --Hypertrophy (increasing muscle size) or maximal strength (lifting heavy loads) NASM Study Guide - fittinpretty.com Designed for individuals who have the goal of hypertrophy, or maximal muscle growth (ie bodybuilders) 4 (4) Maximum Strength Training (5) Power Training --Develop speed and power --Enhance neuromuscular efficiency, prime mover strength, and rate of force production NASM Study Guide - fittinpretty.com Designed for those pursuing maximal prime mover strength by lifting heavy loads --High loads, low repetitions (1-5) --Longer rest breaks Premise: execution of traditional strength exercises (with heavy loads) superset with power exercises (light load, fast). Ex of power exercises: medicine ball chest pass, soccer throw, squat jump. --Superset: 1 strength and 1 power exercise during resistance training --Perform all power exercises as fast as can be controlled 5 Chapter 2 What to Know: Basic Exercise Science Know all definitions Figure 2.34 Figure 2.38 Table 2.5 Muscle Fiber Types Table 2.6 Muscle as Movers Nervous System Kinetic chain: The interaction of the 3 systems responsible for human movement (the nervous, skeletal, and muscular systems) Nervous system: A conglomeration of billions of cells specifically designed to provide a communication network within the human body. The nervous system is divided into two parts: 1) 2) Central Nervous System: brain and spinal cord Peripheral Nervous Systems: nerves (connects CNS to rest of body). 12 cranial nerves, 31 pairs of spinal nerves, and sensory receptors. The PNS is further divided into two systems: a. Somatic Nervous System: Serves outer areas of body and skeletal muscles, provide voluntary control of movement b. Autonomic Nervous System: Supplies neural input to involuntary systems of the body (heart, digestive systems, and endocrine glands) i. The autonomic system is further divided into the sympathetic nervous system (increases activation in preparation for activity) and parasympathetic nervous system (decreases activation during rest and recovery) (Helpful image of nervous system structure on pg. 21) 3 primary functions of the nervous system: NASM Study Guide - fittinpretty.com 6 1) Sensory function: allows body to sense changes in internal/external environment (ie walking on sand to walking on sidewalk) 2) Integrative function: allows body to analyze and interpret sensory information to allow for proper decision making 3) Motor function: neuromuscular response to sensory information (ie changing walking pattern to manage the sand to sidewalk switch) The Neuron: functional unit of the nervous system; a specialized cell that processes and transmits information through electrical and chemical signals. Neurons are composed of three main parts (image on pg. 18): 1) Cell body, including: lysosomes, mitochondria, and a Golgi complex 2) Axon, which provides communication from the brain and spinal cord to the body 3) Dendrites, which gather information from other structures and transmit back to the neuron 3 kinds of neurons: 1) Sensory neurons respond to touch, sound, light, and other stimuli 2) Interneurons transmit nerve impulses between neurons 3) Motor neurons transmit nerve impulses from the brain/spinal cord to the effector sites Sensory receptors convert environmental stimuli into sensory information that the brain/spinal cord use to produce a response. 4 kinds of receptors: 1) 2) 3) 4) Mechanoreceptors respond to mechanical force (touch/pressure) Nociceptors respond to pain Chemoreceptors respond to chemical interaction (smell/taste) Photoreceptors respond to light Muscle spindles are sensory receptors within muscles that run parallel to the muscle fibers and are sensitive to changes in muscle length and rate of length of change. When muscles are stretched, the spindles are also stretched, conveying information to the brain about muscle length. Muscle spindles also help in regulating the contraction of muscles via the stretch reflex mechanism, which prevents overstretching. Golgi tendon organs (located where skeletal muscle fibers insert into the tendons of skeletal muscle) are sensitive to changes in muscular tension and rate of tension change. Activation of the Golgi tendon organ causes muscles to relax, preventing the muscle from excessive stress. NASM Study Guide - fittinpretty.com 7 Joint receptors are located in and around the joint capsule and signal extreme joint positions. Skeletal System 206 bones in the skeletal system, 177 for voluntary movement. More than 300 joints. 2 divisions: Axial—skull, rib cage, and the vertebral column Appendicular—upper and lower extremities, shoulder and pelvic girdles Bones have two jobs: 1) leverage (levers) 2) support (posture) Bone is constantly renewed through a process called remodeling, during which old bone tissue is broken down and removed by cells called osteoclasts and new bone tissue is laid down in its place by osteoblasts. Remodeling tends to follow the lines of stress placed on the bone, meaning that incorrect exercise technique or poor alignment can lead to remodeling processes that reinforce bad posture. So bad posture leads to more bad posture. 5 types of bones: Long—Long cylindrical body with irregular or widened bony ends. Composed predominantly of compact bone tissue to ensure strength and stiffness. Slight curvature good for force distribution. Ex: humerus, femur Components: 1. 2. 3. 4. Epipyhsis: end of long bones—primary site for bone growth Diaphysis: shaft portion of long bone—primary role is support Epiphyseal plate: region connecting the diaphysis to the epiphysis Periosteum: tough, fibrous membrane that coats the bone and plays a fundamental role in movement by providing the point of attachment for tendons 5. Medullary cavity: space running down center of diaphysis, contains marrow that serves as a useful energy reserve 6. Articular (hyaline) cartilage: hard, white, shiny tissue that covers ends of articulating bones—reduces friction in joints NASM Study Guide - fittinpretty.com 8 Short—Similar in length/width, cubical in shape. Spongy bone tissue absorbs shock. Ex: carpals of hands, tarsals of feet Flat—Thin bones comprising two layers of compact bone tissue surrounding a layer of spongy bone tissue. Protects internal structures and provides attachment sites for muscles. Ex: sternum, scapulae, ribs, and cranial bones. Irregular—Bones of unique shape and function that don’t fit other categories. Ex: vertebrae, pelvic bones, and some facial bones Sesamoid—Small bones embedded in a joint capsule or where a tendon passes over a joint. Develop within particular tendons at a site of considerable friction or tension. They improve leverage and protect joints from damage. Ex: patella Bone Markings Necessary for increasing stability in joints and providing attachment sites for muscles. Two types of bone markings: 1. Depressions: Flattened or indented portions of the bone. Examples include: a. Fossa, an attachment site located on the scapulae (shoulder blades) b. Sulcus, a groove in a bone that allows soft tissue (tendons) to pass through. Ex: intertubercular sulcus located in humerus, known as groove for bicep tendon. 2. Processes: Projections protruding from the bone, to which muscles, tendons, and ligaments can attach. Ex: spinous processes (bones jutting out of the back of the neck) Vertebral Column The vertebral column (aka backbone, spinal column) consists of irregularly shaped bones called vertebrae. 5 categories of vertebrae (based on location): 1. First 7 (C1-C7) starting from the top are called cervical vertebrae. 2. Next 12 (T1-T12) are located in the upper/middle back and are called the thoracic vertebrae. 3. Next 5 (L1-L5) are the largest, located in the lower back, and called the lumbar vertebrae. These vertebrae support most of the body’s weight and are subject to the largest forces/stresses along the spine. NASM Study Guide - fittinpretty.com 9 4. The sacrum is a triangular bone just below the lumbar vertebrae. Children have 4-5 sacral vertebrae that fuse into one bone as adults. 5. The coccyx (tailbone) is at the bottom. Children have 3-5 bones that fuse into one as adults. Jobs of the vertebral column: allowing humans to stand upright and maintain their balance, supporting the head and arms while permitting freedom of movement, and acting as an attachment site for several bodily components. Neutral spine: the optimal arrangement of curves, representing a position in which the vertebrae and associated structures are under the least amount of load. 3 major curvatures of the spine: 1. Posterior cervical curvature—posterior concavity of the cervical spine (upper spine curves in) 2. Anterior thoracic curvature—posterior convexity of the thoracic spine (middle spine curves out) 3. Posterior lumbar curvature—posterior concavity of the lumbar spine (lower spine curves in) Joints Joints are formed by one bone that articulates with another bone. Arthrokinematics = joint motion 3 major types of joint motion: 1. Roll, as in a bike tire on a street. Ex: femoral condyles rolling over the tibial condyles during a squat. 2. Slide, as in a bike tire skidding across the street. Ex: tibial condyles sliding across femoral condyles during a knee extension. 3. Spin, like twisting off the lid of a jar. Ex: head of the radius (forearm bone) rotating on the end of the humerus during pronation and supination of the forearm. Kinds of Joints 1. Nonsynovial – no joint cavity or fibrous connective tissue, little or no movement. Ex: sutures of the skull, pubic bones 2. Synovial (most common in the human body, representing 80% of joints) – produces synovial fluid, has a joint cavity and fibrous connective tissue. Kinds of synovial joints: NASM Study Guide - fittinpretty.com 10 Gliding joints – no axis of rotation, moves by sliding side-to-side or back to forth (simplest movement of all joints). Ex: carpals of hand Condyloid joints – formed by the fitting of condyles of one bone into elliptical cavities of another; moves predominantly in one plane. Ex: knee Hinge joints – uniaxial; moves predominantly in one plane of motion (sagittal). Ex: elbow Saddle joints – one bone fits like a saddle on another bone; moves predominantly in two planes (sagittal, joint of thumb frontal). Only ex: carpometacarpal Pivot joints – only one axis; moves predominantly in one plane of motion (transverse). Ex: radioulnar Ball-and-socket joints – most mobile of joints; moves in all three planes of motion. Ex: shoulder Ligaments are fibrous connective tissues that connect bone to bone and provide static and dynamic stability, input to the nervous system (proprioception), guidance, and limitation of improper joint movement. Ligaments are primarily made up of a protein called collagen, along with elastin. Ligaments with higher collagen levels are better suited for resisting strong forces—ie the stabilizing structures of the knee. Ligaments are characterized by having poor vascularity (blood supply), meaning they don’t heal or repair very well. Like muscle, bone is living tissue that responds to exercise by becoming stronger. Individuals who exercise regularly generally achieve greater peak bone mass. The best kind of exercise for bones is weight-bearing exercise (ex: resistance training, walking, body weight squats, push-ups, jogging—NOT swimming or biking), since it forces bones to work against gravity. Muscular System 3 major muscle types in the body: Skeletal Cardiac Smooth Muscles are multiple bundles of muscle fibers held together by connective tissue. Bundle #1: The actual muscle surrounded by connective tissue called epimysium and then wrapped in connective tissue called fascia. NASM Study Guide - fittinpretty.com 11 Bundle #2: The fascicle. Made up of many individual muscle fibers wrapped by connective tissue called endomysium, then wrapped in connective tissue called perimysium. Connective tissues allow forces generated by the muscle to be transmitted from the contractile components of the muscle to the bones, creating motion. Each layer of connective tissue extends the length of the muscle and connects to bone to help form tendons. Tendons attach muscles to bones and provide the anchor from which the muscle can exert force and control the bone and joint. Notable fact: Ligaments and tendons are both known for poor vascularity, leaving them susceptible to slower repair and adaptation. Muscle fibers: Are encased by a plasma membrane called sarcolemma. Contain cell components like a cellular plasma called sarcoplasm, nuclei, mitochondria (which transform energy from food into cell energy), and myofibrils. Myofibrils contain myofilaments, called actin (thin stringlike filaments) and myosin (thick filaments), which are the actual contractile components of muscle tissue. The actin and myosin form repeating sections, separated by Z lines, within a myofibril, and each section is called a sarcomere. Sarcomere: the functional unit of the muscle, much like the neuron is for the nervous system. Two other protein structures important to muscle contraction: Tropomyosin, located on the actin filament, blocks myosin when the muscle is in a relaxed state. Troponin, also located on the actin filament, provides a binding site for both calcium and tropomyosin when a muscle needs to contract. Neural activation is the communication link between the nervous system and the muscular system. A motor unit = one motor neuron and the muscle fibers it innervates with. Neurotransmitters are chemical messengers that cross the synapse between the neuron and muscle fiber, transporting the electrical impulse from the nerve to the muscle. The neurotransmitter NASM Study Guide - fittinpretty.com 12 used by the neuromuscular system is acetylcholine (ACh), which, when attached, stimulates the muscle fibers to go through a series of steps that initiates muscle contractions. Sliding filament theory describes how thick and thin filaments within the sarcomere slide past one another, shortening the entire length of the sarcomere and thus shortening muscle and producing force. Steps are as follows: A sarcomere shortens as a result of the Z lines moving closer together. The Z lines converge as the result of myosin heads attaching to the actin filament and asynchronously pulling the actin filament across the myosin, resulting in shortening of the muscle fiber. The excitation-contraction coupling process is what takes a muscle from neural stimulation through muscle contraction. The “All or Nothing Law”: motor units cannot vary the amount of force they generate; they either contract maximally or not at all. As a result of this law, the overall strength of a muscle contraction depends on the size of the motor unit recruited and the number of motor units activated at a given time. (Large muscles handle large movements, while small movements are made by greater quantities of smaller muscles.) Two categories of muscle fibers: 1. Type I (slow-twitch): contain MORE capillaries, mitochondria, and myoglobin. Often referred to as red fibers since myoglobin appears red. Other characteristics: increased oxygen delivery, smaller in size, less force produced, slow to fatigue, long-term contractions (stabilization) Example usage: sitting upright for a long period of time 2. Type II (fast-twitch): white fibers, FEWER capillaries, mitochondria, and myoglobin. Other characteristics: Decreased oxygen delivery, larger in size, more force produced, quick to fatigue, short-term contractions (force and power) Example usage: performing a sprint Two subcategories of type II: Type IIa: higher oxidative capacity, slower to fatigue. Called immediate fast- twitch fibers, as they can use both aerobic and anaerobic metabolism almost equally to create energy. (Therefore, kind of a combination of type I and type II muscle fibers) Type IIx: low oxidative capacity, quicker to fatigue NASM Study Guide - fittinpretty.com 13 Muscles as Movers (page 42) Muscle Type Agonist Synergist Stabilizer Antagonist Muscle Function Exercise Muscle(s) Used Prime mover (muscles most responsible for a particular movement) Hip extension Gluteus maximus Chest press Pectoralis major Overhead press Deltoid Row Latissimus dorsi Squat Hip extension Gluteus maximus, quadriceps Hamstring complex/erector spinae Chest press Anterior deltoid/triceps Overhead press Triceps Row Posterior deltoid/biceps Squat Hip extension Hamstring complex Transversus abdominis, internal oblique, and multifidus (deep muscles in low back) Chest press Rotator cuff Overhead press Rotator cuff Row Rotator cuff Squat Hip extension Transversus abdominis Psoas (deep hip flexor) Chest press Posterior deltoid Overhead press Latissimus dorsi Row Pectoralis major Squat Psoas (deep hip flexor) Assist prime mover Stabilize while prime mover and synergist work Oppose prime mover NASM Study Guide - fittinpretty.com 14 Endocrine System The endocrine system is a system of glands that secrete hormones into the bloodstream to regulate a variety of bodily functions, including mood, growth and development, tissue function, and metabolism. (Similar to a thermostat.) Consists of: host organs (glands), chemical messengers (hormones), and target cells (receptor cells). Primary endocrine glands: hypothalamus, pituitary (the “master” gland—controls all others), thyroid, and adrenal glands. Carbohydrate (specifically glucose) is the body’s primary energy source during vigorous exercise. Control of blood glucose is regulated by the pancreas, which produces two specific hormones: insulin and glucagon. Insulin: creates glucose stores immediately after meals. Glucagon: Taps into glucose stores long after a meal, converting glycogen back into glucose so it can be released into the bloodstream. 2 Catecholamines: Epinephrine: adrenaline. Results in increased heart rate and stroke volume, elevated blood glucose levels, opened airways, etc. Norepinephrine: opposite of epinephrine, flight or fight response Other key hormones: Testosterone: present in both men and women (10x more in men). Plays a fundamental role in the growth and repair of tissue. Raised levels are indicative of an anabolic (tissue-building) training status. Cortisol: in contrast to testosterone, cortisol represents tissue breakdown. It’s released in times of stress (such as exercise) to maintain energy through the breakdown of carbs, fat, and protein. Too much cortisol (brought by overtraining, excessive stress, poor sleep, or inadequate nutrition) can lead to significant breakdown of muscle tissue, and more. Growth hormone: Responsible for growth and development during childhood up until puberty, when sex hormones take over. Also increases the development of bone, muscle tissue, and protein synthesis; increases fat burning; and strengthens the immune system. NASM Study Guide - fittinpretty.com 15 Thyroid: (Thyroid gland = Adam’s apple) Hormones primarily responsible for human metabolism. Effects of exercise: As activity increases, glucose uptake increases, insulin levels drop, and glucagon secretion by the pancreas increases, helping maintain a steady supply of blood glucose. Testosterone and growth hormone levels increase after strength training and moderate to vigorous aerobic exercise. Same with cortisol levels. NASM Study Guide - fittinpretty.com 16 Chapter 3 What to Know: The Cardiorespiratory System Figure 3.3 Atria and Ventricles know the functions of the right and left atrium and the right and left ventricles Table 3.1 Support Mechanisms of Blood Table 3.2 Structures of the respiratory pump. Cardiorespiratory system = cardiovascular system (heart, blood vessels, and blood) + respiratory system (trachea, bronchi, alveoli, and lungs) Cardiovascular System The heart is contained in the area of the chest called the mediastinum. 3 types of muscle: cardiac (involuntary, striated in appearance), skeletal (voluntary, striated), and smooth (not striated). Intercalated discs between cardiac cells hold muscle cells together during contraction and create electrical connections that allow the heart to contract as one functional unit. Typical resting heart rate: 70-80 BPM. Sinoatrial (SA) node: located in the right atrium, is called the pacemaker for the heart because it initiates the electrical signal that causes the heart to beat. Atrioventricular (AV) node: conducts impulses from the SA node to the ventricles. Heart Structure/Process 1-RIGHT ATRIUM 4-LEFT ATRIUM Deox pool Gathers deoxygenated blood from the body, ready to send to the RV Ox pool Gathers oxygenated blood from the lungs, ready to send to the LV NASM Study Guide - fittinpretty.com 17 2-RIGHT VENTRICLE 5-LEFT VENTRICLE Deox pump to lungs Receives deoxygenated blood from the RA and pumps it to the lungs to get oxygen Ox pump to body Receives oxygenated blood from the LA and pumps it to the body 3-LUNGS (oxygenation) 6-BODY (blood goes into arteries and comes back through veins) Stroke volume: amount of blood pumped out of the heart with each contraction, or the difference between the end-diastolic volume (EDV) and the end-systolic volume (ESV). Typical heart stroke volume: 120 mL EDV and 50 mL ESV = SV of 70 mL. Blood is life-sustaining fluid that supplies organs and cells with oxygen and nutrients, helps regulate body temperature, fight infection, and remove waste products. Average adult has 4-6 L of blood. 3 Types of Blood: Red – carry oxygen from lungs to body White – fights infection Platelets – clotting Blood vessels form a closed circuit of hollow tubes that allow blood to be transported to and from the heart. 3 Types of Blood Vessels: Arteries – carry blood away from the heart Capillaries – where water/chemicals are exchanged between blood and tissues Veins – carry blood back to the heart Respiratory System Including: airways, lungs, and respiratory muscles. Purpose: to bring oxygen into the lungs and remove carbon dioxide, ensuring proper cellular function. Inspiration: activity contracting the inspiratory muscles to move air into the body. Expiration: actively or passively relaxing the inspiratory muscles to move air out of the body. NASM Study Guide - fittinpretty.com 18 Normal breathing: uses primary respiratory muscles (diaphragm, external intercostals) Heavy breathing: additional use of secondary respiratory muscles (scalenes, pectoralis minor) Two respiratory airways: Conducting airways consist of all the structures that air travels through before entering the respiratory airways. (eg nasal/oral cavities, mouth, pharynx, etc.) The structures provide a gathering station, allow the air to be purified, humidified, and warmed/cooled as necessary to match body temp. Respiratory airways collect channeled air from conducting airways and transport oxygen/Co2 in/out of the bloodstream through a process called diffusion. Best measure of cardiorespiratory fitness: maximal oxygen consumption (VO2max). Expensive to test with accuracy, but often estimated through the Rockport Walk Test, Step Test, and YMCA bike protocol test. Results of abnormal breathing patterns: Shallow, upper-chest breathing can become habitual, causing overuse to secondary respiratory muscles. Can affect posture and lead to lightheadedness, headaches, and dizziness. Can lead to altered carbon dioxide and oxygen blood content, leading to feelings of anxiety that further exacerbate the excessive breathing response. Inadequate oxygen and retention of metabolic waste in muscles can create fatigued, stiff muscles. Inadequate joint motion from improper breathing can lead to restricted/stiff joints. NASM Study Guide - fittinpretty.com 19 Chapter 4 What to Know: Exercise Metabolism and Bioenergetics: Be Familiar with all definitions throughout the chapter. Substrates: Primary sources of chemical energy for most organisms, aka the middle product to which all food must be converted to before it can be used as energy. 3 substrates: carbohydrates, fats, and proteins (in order of importance) The energy stored in these substrates is chemically released in cells and stored in the form of a highenergy compound called adenosine triphosphate (ATP). Energy metabolism or bioenergetics: the study of how energy is transformed through various biochemical reactions. The ultimate source of energy is the sun. Metabolism: all the chemical reactions that occur in the body to maintain itself. Exercise metabolism: examination of bioenergetics as it relates to the unique physiological changes and demands placed on the body during exercise. Glucose: A simple sugar manufactured by the body from carbs, fat, and to a lesser extent, protein, which serves as the body’s main source of fuel. Glycogen: The storage form of carbohydrates. When carbohydrate energy is needed, glycogen is converted into glucose for use by muscle cells. Triglycerides: the chemical or substrate form in which most fat exists, both in food and in the body. If fat calories consumed aren’t immediately needed, they’re converted into triglycerides for storage. Protein is generally ignored as a significant fuel for energy metabolism, and only really comes into play during starvation, when it’s required to participate in a special energy-producing process called gluconeogenesis. Cellular Metabolism NASM Study Guide - fittinpretty.com 20 When the chemical bonds of ATP are broken (by an enzyme), energy is released for cellular work and a molecule called adenosine diphosphate (ADP) is dropped. Energy metabolism works to harness enough free energy to reattach a phosphate group to an ADP, thereby turning it back into an ATP. ATP = ADP + Pi (an inorganic phosphate molecule) + energy release The body does not technically make energy—it transfers energy from the sun through food to cells using energy metabolism processes. The specific process used depends on the intensity and duration of the physical activity the body is performing at the time. Energy is used to form the myosin-actin cross-bridges that facilitate muscle contraction. For one cycle of a cross-bridge, two ATPs are needed. 3 different energy metabolism systems (ways to generate ATP): ATP-PC System (immediate use) The simplest and fastest of the energy systems Occurs without oxygen Activated by the onset of activity, regardless of intensity, because of its ability to kick in immediately Provides energy for high-intensity, short-duration activity (as seen in power/strength training) Works by transferring a phosphate (and its energy) from another high-energy molecule called phosphocreatine (abbrev. PC) to an ADP molecule. Glycolysis System (short-term use) Can produce a significantly greater amount of energy than ATP-PC Limited to 30-50 seconds of duration (ideal for an 8-12 repetition exercise) Works by chemically breaking down stored glucose. Before glucose can be used, it must be converted to glucose-6-phosphate. Can be aerobic or anaerobic (with or without oxygen)—process is the same, only the output is different. Without oxygen, the result is lactic acid; with oxygen, the result is pyruvic acid, which is converted into an important molecule used in the Krebs cycle. Oxidative System (long-term use) The slowest, most complex system Ability to produce energy for an indefinite period of time (since everyone has an ample storage of fat) Requires oxygen NASM Study Guide - fittinpretty.com 21 Happens via three sub-processes: Aerobic glycolysis (mentioned above), the Krebs cycle, and the electron transport chain (ETC) Metabolises carbs (via glucose), triglycerides aka fat (via fatty acids), and some proteins (via amino acids). End results are water and carbon dioxide, both easily eliminated. Note: the complete metabolism of a single glucose molecule produces between 35 and 40 ATP. Summary: The amount of energy from stored ATP and phosphocreatine (the first system) is small. The amount of energy from stored carbohydrates (the second system) is greater, but still limited. The amount of available fuel for exercise from fats (the third system) is essentially limitless. The body prefers aerobic or oxidative metabolism because carbon dioxide and water are more easily eliminated. Metabolism during exercise One way to measure work output during exercise is by measuring oxygen consumption. At the start of exercise, aerobic metabolic pathways are too slow to meet demand, so the body relies on anaerobic processes. This oxygen deficit shows up in the sluggishness we feel at the beginning of a workout. As aerobic processes kick in and less energy is derived from anaerobic sources, we begin to feel better. Excess Post-exercise Oxygen Consumption (EPOC): The state in which the body’s metabolism is elevated for a time after exercise. During intermittent exercise, the anaerobic-to-aerobic process occurs multiple times with each change of work requirement. Respiratory quotient (RQ) = the amount of carbon dioxide (CO2) expired divided by the amount of oxygen (O2) consumed. An RQ of 1.0 suggests that 100% of fuel is coming from carbohydrates, whereas an RQ of 0.7 suggests that 100% of fuel is coming from fats. (Anything in the middle is a mix of carbs and fats.) The “fat-burning zone” is a myth because working out at a higher intensity still results in a greater total contribution from fat despite also generating a greater percentage contribution of fuel from carbohydrates.

Figure 5.3 Planes of Motion Table 5.1 Examples of Planes, Motions, and Axes Figure 5.4 Joint Motions Figure 5.5 Joint Motions Figure 5.6 Joint Motions Figure 5.7 Joint Motions Table 5.2 Muscle Action Spectrum 5.3 Common force couples Figure 5.15 Levers Biomechanics: the science concerned with the internal and external forces acting on the human body and the effects produced by these forces. Anatomic Locations Superior: above the point of reference Inferior: below the point of reference Proximal: nearest the center of the body or point of reference Distal: away from the center of the body or point of reference Anterior: on or toward the front of the body Posterior: on or toward the back of the body Medial: relatively closer to the midline of the body Lateral: relatively farther away from the midline or toward the outside of the body Contralateral: opposite side of the body NASM Study Guide - fittinpretty.com 23 Ipsilateral: same side of the body Planes of Motion Although motions can be one-plane dominant, remember that no motion occurs strictly in one plane of motion. Joint motion: movement in a plane that occurs on an axis running perpendicular to that plane, like the axle that a car wheel revolves around. Frontal=Front/back, Sagittal=Sides, Transverse=Top/bottom Sagittal Plane Bisects the body into right and left sides. Movements go forward/backward and up/down. Movements include: Flexion: a bending movement in which the relative angle between two adjacent segments decreases. NASM Study Guide - fittinpretty.com 24 Extension: a straightening movement in which the relative angle between two adjacent segments increases. Examples of sagittal plane movements: bicep curls, tricep pushdowns, squats, front lunges, calf raises, walking, running vertical jump, climbing stairs, and shooting a basketball. Hyperextension is the extension of a joint beyond the normal limit or range of motion, often resulting in injury. Frontal Plane Bisects the body into front and back halves. Movements go side-to-side. Movements include: Adduction: a movement of the segment toward the midline of the body (or similar to flexion, a decrease in the angle between two adjoining segments, but in the frontal plane) Abduction: a movement away from the midline of the body (or similar to extension, an increase in the angle between two adjoining segments, but in the frontal plane) Examples of frontal plane movements: side lateral raises, side lunges, and side shuffling. Transverse Plane Bisects the body into upper and lower halves. Movements are rotations. Movements include: Internal rotation: rotation of a joint toward the middle of the body. External rotation: rotation of a joint away from the middle of the body. Horizontal abduction: movement of the arm or thigh in the transverse plane from an anterior position to a lateral position. Horizontal adduction: movement of the arm or thigh in the transverse plane from a lateral position to an anterior position. Examples of transverse plane movements: cable trunk rotations, dumbbell chest fly, throwing a ball/Frisbee, golfing, swinging a bat. Scapular Motion NASM Study Guide - fittinpretty.com 25 Motion of the shoulder blades. Movements include: Retraction (“adduction”): Shoulder blades come close together. Protraction (“abduction”): Shoulder blades move farther away from each other. Elevation: Should blades move upward toward ears. Depression: Shoulder blades move downward. Muscle Actions Isotonic (iso = equal, tonic = tension): constant muscle tension Eccentric: deceleration (lowering a weight) Concentric: acceleration (lifting a weight) Isometric (iso = equal, metric = length): constant muscle length Isokinetic (iso = equal, kinetic = motion): constant velocity of motion Isotonic: Force is produced, muscle tension developed, and movement occurs through range of motion. Two phases of isotonic movement: 1. Eccentric: A muscle develops tension while lengthening (actin and myosin cross-bridges are pulled apart and reattached). Lengthening happens because the contractile force is less than the resistive force. Moving in the same direction as the resistance, decelerates/reduces force Examples: landing from a jump, lowering a weight 2. Concentric: The contractile force is greater than the resistive force, resulting in shortening of the muscle and visible joint movement (actin and myosin cross-bridges move together, known as sliding-filament theory). Moving in opposite direction of force, accelerates/produces force Examples: jumping upward, lifting a weight NASM Study Guide - fittinpretty.com 26 Isometric: No visible movement with or against resistance, dynamically stabilizing force. Contractile force is equal to resistive force, leading to no visible change in muscle length. Examples: Pausing between lifting and lowering in resistance training. Adductors and abductors of the thigh during a squat dynamically stabilize the leg from moving too much in the frontal and transverse planes. During a ball crunch, the transversus abdominis and multifidus muscles stabilize the lumbar spine. Isokinetic: Muscle shortens at a constant speed over the full range of motion. Speed of movement is fixed, resistance varies with the force exerted. Ie the harder an individual pushes or pulls, the more resistance they feel. Muscle tension is at its maximum throughout the whole range of motion. Requires sophisticated training equipment. Examples of Muscle Actions: Bicep Curl 1. Lift dumbbell. Concentric action, muscle shortening. 2. Hold dumbbell at shoulder. Isometric action, muscle length unchanged. 3. Lower dumbbell. Eccentric action, muscle lengthening. Squat 1. Squat down. Lowering movement = eccentric action. 2. Pause at bottom. Isometric action. 3. Return to standing. Lifting movement = concentric action. Force: the interaction between two entities or bodies that results in either the acceleration or deceleration of an object. Characterized by magnitude (how much) and direction. Muscle Relationships NASM Study Guide - fittinpretty.com 27 Length-tension relationships: the resting length of a muscle and the tension the muscle can produce at this resting length. Optimal muscle length = actin and myosin filaments in the sarcomere have the greatest degree of overlap, allowing for the max amount of connections between the two and max force production. Lengthening a muscle beyond this optimal length reduces overlap and force production. If muscle lengths are altered (ie misaligned joints—poor posture), they will not generate the needed force to allow for efficient movement. Force-velocity curve: the relationship of muscle’s ability to produce tension at differing shortening velocities. As the velocity of a concentric muscle action increases, its ability to produce force decreases. Aka the faster you lift, the harder it gets. (Reverse is true for eccentric actions: as velocity increases, force production increases.) Force-couple relationships: muscle groups working together to produce movement around a joint. Muscles in a force-couple provide divergent pulls on the bone or bones they connect with. All muscles working in unison to produce a desired movement are said to be working in a force-couple. Proper force-couple relationships rely on proper length-tension relationships and joint motion. Common Force-Couples Muscles Movement Internal/external obliques Upper trapezius and lower portion of serratus anterior Gluteus maximus, quads, and calf muscles Trunk rotation Upward rotation of scapula Gastrocnemius, peroneus longus, and tibialis posterior Deltoid and rotator cuff Hip and knee extension during walking, running, etc. Performing plantarflexion at the foot and ankle complex Performing shoulder abduction Muscle Levers Joint motion is caused by muscles pulling on bones; muscles cannot actively push. A lever consists of a rigid “bar” that pivots around a stationary fulcrum (pivot point). In the body, the fulcrum is the joint axis, bones are the levers, muscles create the motion, and resistance can be body weight or object weight. 3 kinds of levers: NASM Study Guide - fittinpretty.com 28 First-class: Fulcrum in the middle, like a seesaw. Example: nodding the head. Second-class: Resistance in the middle (with fulcrum and effort on either side), like a load in a wheelbarrow. Examples: full-body push-ups or calf raises. Third-class: Effort in the middle (between resistance and fulcrum). Most limbs of the human body are third-class levers. Examples: human forearm during bicep curl (fulcrum = elbow, effort = bicep, load = dumbbell). Rotary motion: movement around an axis. Torque: a force that produces rotation, measured in newton-meters or Nms. The difference between the distance a weight is from the center of a joint and the muscle’s attachment and line of pull (direction through which tension is applied through the tendon) is from the joint will determine the efficiency with which the muscles manipulate the movement. Ie: the closer a weight is to the point of rotation (the joint), the less torque it creates (and the easier the movement becomes). Motor Behavior Motor behavior: the HMS response to internal and external environmental stimuli. The collective study of 3 things: 1. Motor control: how the central nervous system integrates internal and external sensory information with previous experiences to produce a motor response. 2. Motor learning: utilization of motor control through practice and experience, leading to skilled movement. (Examples: riding a bike, playing the piano) 3. Motor development: the change in motor behavior over time, throughout a lifespan. Muscle synergies: groups of muscles that are recruited by the central nervous system to provide movement. With proper technique, synergies become increasingly fluent and automated. Sensorimotor integration: the ability of the nervous system to gather and interpret sensory information and to select and execute proper motor responses. This process works as long as incoming sensory information is good. Individuals training using improper form will develop improper sensory information, leading to movement compensations and potential injury. Feedback: the use of sensory information and sensorimotor integration to help the human movement system in motor learning. 2 kinds: NASM Study Guide - fittinpretty.com 29 1. Internal Feedback (sensory feedback): the process whereby sensory information is used by the body to reactively monitor movement and the environment. 2. External Feedback: information provided by an external source, such as a trainer or mirror, to supplement internal feedback. 2 Forms of external feedback: a. Knowledge of results: telling a client how they did after performing a move. b. Knowledge of performance: providing feedback during a movement. It is important that clients do not become dependent on external feedback, as this may detract from their responsiveness to internal sensory input. Clients should be encouraged to pay attention to how their body feels when they are performing a movement correctly. REVIEW TIPS FROM NASM – Chapter 5 The planes of motion can be a bit tricky, so here is a little bit of clarification: Frontal Plane NOT front to back movements Side to side movements Exercises involving abduction and/or adduction of the limbs Example: side lunge, lateral dumbbell raise, ice skater Imagine a wall in front and in back of you. The ONLY movement this would allow is along that planesideways movements. Sagittal Plane Forward and backwards movements Movements involving pushing and/or pulling Movements involving flexion and/or extension at joints Example: bicep curl, front lunge, bench press, and rows Imagine a wall on your right and left side. The ONLY movement this would allow is along that plane-or front and back movements. NASM Study Guide - fittinpretty.com 30 Transverse Plane Rotational movements Diagonal movements Example: rotation, wood-chop throw, medicine ball rotation chest pass NASM Study Guide - fittinpretty.com 31 Chapter 6 What to Know: Fitness Assessments This is going to be a very important chapter to know as a lot of test question will be taken from this chapter. Table 6.1 Guidelines for Health and Fitness Professionals Figure 6.1 Subjective vs. Objective information Figure 6.2 Sample Physical Activity Readiness Questionnaire Figure 6.3 Sample questions: client occupation Figure 6.4 Sample questions: client lifestyle Figure 6.5 Sample questions: client medical history Table 6.2 Common medications by classification Table 6.3 Effects of medication on heart rate and blood pressure Heart rate and blood pressure assessments Table 6.4 Target heart rate training zones Max Heart Rate formula (straight percentage method) for each zone Body Composition Assessments Circumference measurements Body Mass Index YMCA 3-minute step test Rockport Walk Test Table 6.9 Pronation Distortion Syndrome Table 6.10Lower Crossed Syndrome Table 6.11Upper Crossed Syndrome Be familiar with all of the assessment protocols and for the posture assessments all compensations NASM endorses a “start low and go slow” approach to exercise. Fitness assessments allow PTs to continually monitor a client’s needs, functional capabilities, and physiologic effects of exercise, enabling the client to realize the full benefit of an individualized training program. NOT designed to diagnose medical/health conditions or prescribe treatment of any kind. Designed to serve as a way of observing/documenting clients’ structural/functional status. Fitness assessments include: Pre-participation health screening NASM Study Guide - fittinpretty.com 32 Resting physiologic measurements (heart rate, blood pressure, height, weight) Measurements to help determine fitness level Subjective information: general and medical history (occupation, lifestyle, personal info) Objective information: physiologic assessments, body composition testing, cardiorespiratory assessments, static and dynamic postural assessments, performance assessments The Physical Activity Readiness Questionnaire (PAR-Q) has been designed to determine the safety or possible risk of exercising for a client based on the answers to specific health history questions. Primarily aimed at identifying individuals at risk of cardiovascular disease (CVD) who would need further evaluation from a doctor before proceeding. Common Movement Patterns and Potential Impacts Extended periods of sitting tight hip flexors, postural imbalances, potentially poor cardiorespiratory conditioning Repetitive movements pattern overload to muscles and joints, leading to tissue trauma and kinetic chain dysfunction. Working with arms overhead may lead to shoulder/neck soreness, tightness in lats and weakness in rotator cuff. Dress shoes decreased dorsiflexion and overpronation at the foot and ankle complex, resulting in flattening of the arch of the foot Mental stress elevated resting heart rate, blood pressure, and ventilation at rest and exercise. (Review effects of medication on heart rate and blood pressure chart on page 108) Heart rate assessment Resting heart rate is a fairly good indicator of overall cardiorespiratory fitness, whereas exercise HR is a strong indicator. 7 pulse points—most common: radial and carotid arteries Resting heart rate should be determined by having the client record it 3 mornings in a row and take the average Typical resting heart rate = 70-80 BPM (Average for men =70, average for women = 75) Estimated maximal heart rate = 220 – age NASM Study Guide - fittinpretty.com 33 Heart Rate Training Zones Zone One Two Three Purpose Build aerobic base/aid in recovery Increase aerobic and anaerobic endurance Build high-end work capacity Intensity 65-75% 76-85% 86-95% Heart rate reserve (HRR) aka the Karvonen method is a method of establishing training intensity on the basis of the difference between a client’s predicted maximal heart rate and their resting heart rate. Target heart rate (THR) = [(HRmax – HRrest) x desired intensity] + HRrest Blood pressure assessment Systolic (pressure within the arterial system after the heart contracts) / Diastolic (pressure within the arterial system when the heart is resting and filling with blood) Acceptable blood pressure = 120/80 mm Hg or less Body composition: the relative percentage of body weight that is fat versus fat-free tissue, aka “percent body fat” Percent Fat Standards Essential Athletic Recommended (34 years or less) Recommended (35-55) Recommended (56 and up) Men 3-5% 5-13% 8-22% 10-25% 10-25% Women 8-12% 12-22% 20-35% 23-38% 25-38% Body Composition Assessments: Skinfold measurement w/calipers Bioelectical impedance w/an electrical current Underwater weighing (aka hydrostatic weighing) Body Fat Percentage NASM Study Guide - fittinpretty.com 34 Calculate with the Durnin formula Measure 4 skinfolds: biceps, triceps, subscapular (back fat), and iliac crest (love handles), then plug into chart with sex and age Body fat % x scale weight = fat mass Scale weight – fat mass = lean body mass Circumference Measurements Can be used on obese clients Good for comparisons/progressions Good for assessing fat pattern/distribution Inexpensive Easy to record The 7 measurements include: neck, chest, waist, hips, thighs, calves, and biceps Waist-to-hip ratio (divide waist by hip)—should be no higher than 0.8 for women and 0.95 for men. BMI = Weight (kg) / Height (m^2) OR BMI = [Weight (lbs) / Height (inch ^2)] x 703 BMI with lowest risk of disease = 22-24.9 Cardiorespiratory Assessments Most valid measurement: cardiopulmonary exercise testing (CPET) or maximal oxygen uptake. Often not practical due to cost, time involved, and willingness of client to perform at max physical capacity. Submaximal testing allows for the prediction or estimation of VO2max (maximal oxygen uptake). YMCA 3-Minute Step Test: 96 steps/minute on a 12-inch step. Measure heart rate afterwards for 60 seconds. Compare to chart. NASM Study Guide - fittinpretty.com 35 Rockport Walk Test: Record the client’s weight. Have the client walk 1 mile as fast as possible on a treadmill. Record the time. Record the client’s HR. Use the formula to calculate oxygen consumption. Posture and Movement Assessments Proper posture: Ensures that the muscles of the body are optimally aligned at the proper length-tension relationships necessary for efficient functioning of force-couples. This in turn ensures proper joint motion, maximal force production, and reduced risk of injury. Helps the body produce high levels of functional strength. Without it, the body may degenerate or experience altered movement patterns and muscle imbalances. The use of a static postural assessment (assessment of resting posture) is the basis for identifying muscle imbalances. 3 primary postural distortion patterns: Pronation distortion syndrome: flat feet, knock knees Lower crossed syndrome: arched lower back Upper crossed syndrome: forward head, rounded shoulders NASM Study Guide - fittinpretty.com 36 Static Postural Assessment Check for: neutral alignment, symmetry, balanced muscle tone, and specific postural deformities. Focus on the kinetic chain checkpoints: Foot and ankle, knee, lumbo-pelvic-hip complex (LPHC), shoulders, head and cervical spine Anterior View (from the front) Foot/ankles: Straight and parallel, NOT flattened/externally rotated Knees: In line with toes, NOT adducted or abducted LPHC: Pelvis level with both anterior superior iliac spines in same transverse plane Shoulders: Level, NOT elevated or rounded Head: Neutral position, NOT tilted or rotated Lateral View (side) NASM Study Guide - fittinpretty.com 37 Foot/ankles: Neutral position, leg vertical at right angle to sole of foot Knees: Neutral position, NOT flexed nor hyperextended LPHC: Pelvis neutral position, NOT anteriorly (lumbar extension) or posteriorly (lumbar flexion) rotated Shoulders: Normal kyphotic curve, NOT excessively rounded Head: Neutral position, NOT in excessive extension (jutting forward) Posterior View (side) Foot/ankles: Heels straight and parallel, NOT overly pronated Knees: Neutral position, NOT adducted or abducted LPHC: Pelvis level, as above Shoulders: Level, NOT elevated or protracted Head: Neutral, NOT tilted or rotated Dynamic Postural Assessments 1) Overhead Squat Assesses dynamic flexibility, core strength, balance, and overall neuromuscular control. (Same as singleleg squat.) Look for these 5 compensations: NASM Study Guide - fittinpretty.com 38 2) Single Leg Squat Assesses dynamic flexibility, core strength, balance, and overall neuromuscular control. (Same as overhead squat.) NASM Study Guide - fittinpretty.com 39 3) Pushing Assessment Assesses: movement efficiency and potential muscle imbalances during pushing movements. 4) Pulling Assessment Assesses: movement efficiency and potential muscle imbalances during pulling movements. NASM Study Guide - fittinpretty.com 40 NASM Study Guide - fittinpretty.com 41 Performance Assessments 1) Push-up Test Measures muscular endurance of the upper body, primarily the pushing muscles. Process: Perform push-ups for 60 seconds or to exhaustion without compensating. Must touch chest to floor. PT records number of touches. 2) Davies Test Assesses upper extremity agility and stabilization. Process: In push-up position, client switches off touching two points 36 inches apart with the opposite hand. PT records number of touches in 15 seconds. 3) Shark Skill Test Assesses lower extremity agility and neuromuscular control. Process: Client stands on a 9-square grid, hands on hips, standing on one leg. Follows directions to hop from box to box in a certain pattern, always returning to center. Deductions recorded for: non-hopping leg touching ground, hands coming off hips, foot going into wrong square, foot not returning to center square. 4) Upper Extremity Strength Assessment (Bench Press) Estimates one-rep maximum on overall upper body strength of the pressing musculature. Considered an advanced assessment for strength-specific goals only. Process: Warm up with light resistance for 8-10 reps. Take a 1 min rest. Add 10-20 lbs. for 3-5 reps. Take a 2 min rest. Repeat last two steps until failure between 2-10 reps. Use chart to estimate one-rep max. 5) Lower Extremity Strength Assessment (Squat) Estimates one-rep maximum for squats and overall lower body strength. Considered an advanced assessment for strength-specific goals only. Process: Warm up with light resistance for 8-10 reps. Take a 1 min rest. Add 30-40 lbs. for 3-5 reps. Take a 2 min rest. Repeat last two steps until failure between 2-10 reps. Use chart to estimate one-rep max. NASM Study Guide - fittinpretty.com 42 Chapter 7 What to Know: Flexibility Training Concepts: Know all definitions throughout the chapter Figure 7.10 Integrated flexibility Continuum Table 7.2 Examples of stretching within the Flexibility Continuum Myofascial Release Table 7.3 Static Stretching Summary Table 7.4 Active-Isolated Stretching summary Table 7.5 Dynamic Stretching summary Mechanoreceptors = a Golgi tendon organ (GTO) and muscle spindle fibers GTO Muscle Spindle Fibers Senses muscle tension Senses muscle lengthening Relaxes the muscle in response Contracts the muscle in response Normal reaction to avoid injury Normal reaction to avoid injury Focus on page 183!! Look at each overactive muscle and refer back to Appendix D (pages 575-596). Look at each muscle's "Isolated Function". Some muscles will over-do their "Isolated Function". Other muscles tend to be "victims of association". This means that they may become synergistically dominant because a muscle nearby becomes underactive/lengthened/weak. In addition, by having a general idea of what each muscle's "Isolated Function" is, you will be able to figure out exercises that directly work those muscles. Think of muscles in terms of antagonistic (one is an agonist while the other is an antagonist) actions. When an agonist contracts, the antagonist will relax. Also keep in mind that several muscles may have similar actions and that the exact movement of a bone will be the result of a coordinated effort involving many muscles (force couples). Muscles function in integrated groups to allow for neuromuscular control during movement. A muscle's integrated muscle function is the action it naturally tends to perform when it works in conjunction with other muscles. By isolating each muscle on the other hand, and tracing them from their point of origin to their insertion, one can gain a better understanding of that muscle's main function. A muscle's isolated function is what that individual muscle is meant to do, alone, and isolated from all other muscles. NASM Study Guide - fittinpretty.com 43 An advanced knowledge in anatomy is required to identify muscle functions such as agonists, antagonists, synergists, and stabilizers. For example, most stabilizers are proximal to the joint they stabilize, but it is dependent on the movement that is occurring. Stabilizers are generally smaller in size, made up of type I muscle fibers (slow twitch), and they are prone to weakness. Some examples of stabilizers include (1) rotator cuff – shoulder (2) core inner unit – multifidus, transverse abdominus, pelvic floor muscles, internal oblique – stabilize pelvis and spine (3) kneeVMO, popliteus – knee. For the exam you only need an understanding of this concept to the degree the textbook discusses. Flexibility: the ability to move a joint through its complete range of motion. ROM is dictated by the normal extensibility of all soft tissues surrounding the joint. Soft tissue will only achieve efficient extensibility if optimal control of movement is maintained throughout the entire ROM. Dynamic range of motion: the optimal control of movement throughout a joint’s entire ROM. It is the combination of flexibility and the nervous system’s ability to control ROM efficiently. Neuromuscular efficiency: the ability of the nervous system to recruit the correct muscles to produce force (concentrically), reduce force (eccentrically), and dynamically stabilize (isometrically) the body. Flexibility requires extensibility, which requires dynamic range of motion, which requires neuromuscular efficiency. Postural distortion pattern: predictable patterns of dysfunction that develop when the HMS is misaligned and not functioning properly over time. Muscle imbalance poor posture improper movement injury. Relative flexibility: altered movement patterns, or the tendency of the body to seek the path of least resistance during functional movement patterns. (Ex: squatting with feet externally rotated due to tight calf muscles.) Muscles imbalances: alterations in the lengths of muscles surrounding a given joint, in which some are overactive and others underactive. Reciprocal inhibition: the simultaneous relaxation of one muscle and the contraction of its antagonist to allow movement to take place. (A naturally occurring, healthy phenomenon.) NASM Study Guide - fittinpretty.com 44 Altered reciprocal inhibition: a muscle inhibition, caused by a tight antagonist, which inhibits its functional antagonist. (Ex: a tight psoas, hip flexor, decreases neural drive of the glutes, hip extensors.) Synergistic dominance: a neuromuscular phenomenon that occurs when synergists take over function for a weak or inhibited prime mover. Arthrokinematics: the motions of joints in the body. Arthrokinetic dysfunction: a biomechanical and neuromuscular dysfunction leading to altered joint motion. Muscle spindles help prevent muscles from stretching too far or too fast. However, when a muscle on one side of a joint is lengthened (because of a shortened muscle on the opposite side), the spindles of the lengthened muscle are stretched. This info is transmitted to the brain and spinal cord, exciting the muscle spindle and causing the muscle fibers of the lengthened muscle to contract. This often results in micro spasms or a feeling of tightness. When a lengthened muscle is stretched, it increases the excitement of the muscle spindles and further creates a contraction (spasm) response. Autogenic inhibition: The process by which neural impulses that sense tension are greater than the impulses that cause muscles to contract, providing an inhibitory effect to the muscle spindles. (Called autogenic because the muscle is being inhibited by its own receptors.) Stretches should be held long enough for the Golgi tendon organ to override the signal from the muscle spindle (approx. 30 seconds). Pattern overload: consistently repeating the same pattern of motion, which may place abnormal stresses on the body. Cumulative injury cycle: Tissue trauma inflammation muscle spasm adhesions altered neuromuscular control muscle imbalance. Any trauma to the tissue of the body creates inflammation. Inflammation, in turn, activates the body’s pain receptors and initiates a protective mechanism, increasing muscle tension or causing muscle spasm. Davis’s law states that soft tissue models along the lines of stress. 3 phases of flexibility training: 1. Corrective NASM Study Guide - fittinpretty.com 45 Designed to increase joint ROM, improve muscle imbalances, and correct altered joint motion. Includes: self-myofascial release and static stretching. Appropriate for: phase 1 of OPT. 2. Active Designed to improve extensibility of soft tissue and increase neuromuscular efficiency using reciprocal inhibition. Includes: self-myofascial release and active-isolated stretching. A-I stretching allows for agonists and synergist muscles to move a limb through a full ROM while the functional antagonists are being stretched. Appropriate for: phases 2, 3, and 4 phases of OPT. 3. Functional Includes: self-myofascial release and dynamic stretching. Dynamic stretching requires integrated, multiplanar soft tissue extensibility, with optimal neuromuscular control, through full ROM, or movement without compensation. Appropriate for: phase 5 of OPT. Stretching Techniques Myofascial Release focuses on the neural system and fascial system in the body (fibrous tissue that surrounds and separates muscle tissue). By applying gentle force to a knot, the elastic muscle fibers are altered from a bundled position into a straighter alignment. Gentle pressure stimulates the Golgi tendon organ and creates autogenic inhibition, decreasing muscle spindle excitation and releasing the hypertonicity (tension) of the underlying muscles. Must sustain pressure on a spot for 30 seconds. Examples: Foam roll calves (leaning back, ankles crossed), IT band (outer thigh, other leg draped over that leg), adductors (inner thighs, on elbows), piriformis (butt, ankle on knee), latissimus dorsi (upper side, arm extended overhead) Static Stretching is the process of passively taking a muscle to the point of tension and holding the stretch for 30 seconds min. It combines low force with longer duration. The Golgi tendon organ is stimulated and an inhibitory effect is produces (autogenic inhibition). Contracting the antagonistic muscle while holding the stretch can reciprocally inhibit the muscle being stretched, enhancing the stretch. Examples: Static gastrocnemius stretch (press wall, back heel on ground), static standing TFL stretch (raise arm up and over), static kneeling hip flexor stretch (kneel forward on knee, arm raised), static standing adductor stretch (side lunge), static latissimus dorsi NASM Study Guide - fittinpretty.com 46 ball stretch (reach arm straight by rolling ball), static pectoral stretch (press forward into shoulder), static upper trapezius/scalene stretch (pull head to side) Active-Isolated Stretching is the process of using agonists and synergists to dynamically move the joint into a range of motion. Increases motorneuron excitability, creating reciprocal inhibition of the muscle being stretched. Recommended for warm-up. Examples: Active supine biceps femoris stretch (lay on back, draw knee over opposite leg), active standing adductor stretch (side lunges to each side). Dynamic Stretching uses the force production of a muscle and the body’s momentum to take a joint through the full available range of motion. Uses reciprocal inhibition to improve soft tissue extensibility. Perform 10 reps using 3-10 dynamic stretches. Examples: Hip swings, medicine ball rotations, walking lunges, prisoner squat, tube walking side to side. Controversial stretches: inverted hurdler’s stretch, plow, shoulder stand, straight-leg toe touch, arching quadriceps NASM Study Guide - fittinpretty.com 47 NASM Study Guide - fittinpretty.com 48 Chapter 8 What to Know: Cardiorespiratory Fitness Training Know all definitions throughout the chapter: Overtraining page General vs. Specific Warm-up Cool down Phase Figure 8.1 FITTE factors Table 8.9 Training Zones Circuit Training Cardiorespiratory fitness: the ability of the circulatory and respiratory systems to supply oxygenrich blood to skeletal muscles during sustained physical activity. One of 5 components of physical fitness, along with muscular strength, muscular endurance, flexibility, and body composition. Cardio is a top priority from the standpoint of preventing chronic disease and improving health and quality of life. Integrated cardiorespiratory training: systematically progressing clients through various stages to achieve optimal levels of physiological, physical, and performance adaptions by placing stress on the cardiorespiratory system. Each cardio session should include a warm-up, conditioning phase, and cool-down. General warm-up (movement not related to actual activity) vs. specific warm-up (movement related to activity, aka dynamic stretches, such as squats and push-ups before weight training) Purpose of warm-up: increase heart and respiratory rates, increase tissue temperature, and psychologically prepare the individual for higher intensity. Warm-up guidelines: 5-10 minutes of low-to-moderate intensity Goal of cool-down: reduce heart and breathing rates, gradually cool body temperature, return muscles to their optimal length-tension rates, prevent venous pooling of blood in lower extremities, and restore physiological systems to baseline. NASM Study Guide - fittinpretty.com 49 At rest, only 15-20% of circulating blood reaches skeletal muscle, but during intense vigorous exercise it increases to as much as 80-85% of cardiac output. During intense exercise, plasma volume can decrease by as much as 10-20%. Static stretching guidelines: During warm-up, static stretching should only be used on areas assessed as tight/overactive. Hold stretches for 20-30 seconds. During cool-down, it should be used on the major muscles used during the workout, to return them to normal resting lengths. Suggested Warm-Up Activities Stabilization clients: self-myofascial release (30 sec/muscle), static stretching (30 sec/muscle), cardio (5-10 min) Strength clients: self-myofascial release (30 sec/muscle), active-isolated stretching (1-2 sec, 510 reps/muscle), cardio (5-10 min) Power clients: self-myofascial release (30 sec/muscle) and dynamic stretching (10 reps/side) FITTE principle: Frequency (# training sessions in a time period), intensity (level of demand on the body), time (length of time engaged in activity), type (mode or type of activity selected), and enjoyment. Frequency: for general health, need small quantities of activity every day. For improved fitness, higher intensity work 3-5 days/week. Intensity: calculated via heart rate, power output (watts), or % maximal oxygen consumption (Vo2max) or oxygen uptake reserve (Vo2R). Moderate intensity = less than 60% Vo2R or passable talktest range. (Intensities greater than that are required to improve fitness.) Recommended intensity = 4085% (40% being the threshold for deconditioned individuals). Ways to measure Vo2: 1. 2. Peak Vo2 Method: best, but not realistic. Vo2 Reserve Method: simple and preferred. Target Vo2R = [(Vo2max – Vo2rest) x intensity desired] + Vo2rest 3. Peak Metabolic Equivalent (MET) Method: METs used to describe the energy cost of physical activity as multiples of resting metabolic rate. 1 MET = 3.5 mL O2 kg min or the equivalent of the average resting metabolic rate (RMR) for adults. 4. Peak Maximal Heart Rate (MHR) Method: 220-age. Not intended to be used to guide training. NASM Study Guide - fittinpretty.com 50 5. HR Reserve (HRR) Method: Aka Karvonen method, the difference between the client’s predicted max heart rate and their resting heart rate. THR = [(HRmax – Hrrest) x desired intensity] + HRrest 6. Ratings of Perceived Exertion Method: Moderate intensity is equal to “somewhat hard” (12-14) on the 6-20 Borg scale. 7. Talk Test Method: Work until you can’t speak comfortably. Ventilatory threshold: the point during graded exercise in which ventilation increases disproportionately to oxygen uptake, signifying a switch from predominately aerobic energy production to anaerobic energy production. Time recommendations: 2 hours and 30 minutes (150 min) of moderate-intensity aerobic activity (aka brisk walking) every week OR 1 hour 15 minutes (75 min) of vigorous-intensity aerobic activity (jogging or running) OR A mix of intensities Type: For an activity to be considered aerobic, it must: be rhythmic in nature, use large muscle groups, and be continuous. Principle of specificity: the body will adapt to the level of stress placed on it and will then require more or varied amounts of stress to produce a higher level of adaptation in the future. Overtraining: Excessive frequency, volume, or intensity of training, resulting in fatigue (which is also caused by a lack of proper rest and recovery) 3 Stages of Cardio Training: Stage 1: Target heart rate of 65-75%, or 12/13 on the perceived exertion scale. Start slowly and work up to 30-60 minutes continuous exercise. When they can maintain zone one heart rate for 30 minutes 2-3 times a week, ready for stage 2. Stage 2: Focus on increasing workload (speed, incline, level). Target heart rate of 76-85% or 14-16 perceived exertion. Alternate with stage 1 within the workouts and between days at first. Progress from a work-to-rest ratio of 1:3 to 1:1. Stage 3: Target heart rate of 86-95% or 17-19 perceived exertion. NASM Study Guide - fittinpretty.com 51 Circuit training allows for comparable fitness results without spending extended periods of time to achieve them. It’s proven to provide higher post-exercise metabolic rates as well as strength levels. Postural consideration for clients with anteriorly rotated pelvis and arched lower back (lower crossed syndrome): initial use of bicycles or steppers might not be warranted, as the hips are placed in a constant state of flexion, adding to a shortened hip flexor complex. Also, treadmill speed should be kept to a controllable pace to avoid overstriding. NASM Study Guide - fittinpretty.com 52 Chapter 9 What to Know: Core Training Concepts Know all definitions throughout the chapter Local Stabilization System Global Stabilization System Table 9.1 Muscles of the Core It is your responsibility to learn how to categorize, progress, and regress body position while performing certain types of exercises. The OPT model is divided into three different blocks of training and each building block contains specific phases of training that systematically advances the student in a safe and progressive manner. Exercises can be categorized by adaptation and by type of exercise: OPT Level (adaptation): Stabilization, Strength, or Power (be familiar with all exercises listed, as well as how to regress and progress the exercises listed) Type of Exercise: Core Table 9.3 Core training program design A weak core is a fundamental problem inherent to inefficient movement that may lead to predictable patterns of injury. Core: the structures that make up the lumbo-pelvic-hip complex (LPH), including the lumbar spine, the pelvic girdle, abdomen, and the hip joint. Where the body’s center of gravity (COG) is located and where all movement originates. Local stabilization system: muscles that attach directly to the vertebrae. Consist primarily of type I (slow twitch) muscle fibers with a high density of muscle spindles. Primarily responsible for intervertebral and intersegmental stability; work to limit excessive compressive, shear, and rotational forces between spinal segments. Primary muscles: transverse abdominis, internal obliques, multifidus, pelvic floor musculature, and diaphragm. Global stabilization system: muscles that attach from the pelvis to the spine. Act to transfer loads between the upper extremity and lower extremity NASM Study Guide - fittinpretty.com 53 Provide stability between the pelvis and spine, provide stabilization and eccentric control of the core during functional movements. Primary muscles: quadratus lumborum, psoas major, external obliques, portions of the internal oblique, rectus abdominis, gluteus medius, and adductor complex. Movement system: muscles that attach the spine and/or pelvis to the extremities. Primarily responsible for concentric force production and eccentric deceleration during dynamic activities. Primary muscles: latissimus dorsi, hip flexors, hamstring complex, and quadriceps Train muscles from the inside out (local global movement) Drawing-in maneuver: used to recruit the local core stabilizers by drawing the navel in toward the spine. Bracing: contracting the abdominal, lower back, and buttock muscles at the same time. Exercises performed in an unstable environment have been demonstrated to increase activation of the local and global stabilization system when compared to traditional trunk exercises. Goal of core training: develop optimal levels of neuromuscular efficiency, stability (intervertebral and lumbopelvic stability—local and global stabilization systems), and functional strength (movement system). Neural adaptions become the focus of the program instead of striving for strength gains. 1. Intervertebral stability 2. Lumbopelvic stability 3. Movement efficiency Clients begin at the highest level at which he can maintain stability and optimal neuromuscular control. 3 levels of core training: 1. Core-stabilization training (Phase 1): designed to improve neuromuscular efficiency and intervertebral stability, focusing on drawing in and bracing during exercises. 2. Examples: marching, floor bridge, floor prone cobra, prone is-abs (plank) Core strength (Phase 2, 3, 4): Designed to improve dynamic stabilization, concentric strength, eccentric strength, and neuromuscular efficiency of the entire kinetic chain. More dynamic eccentric and concentric movements of the spine throughout a full ROM, while still drawing in and bracing. NASM Study Guide - fittinpretty.com 54 3. Examples: ball crunch, back extensions, reverse crunch, cable rotations Core power (Phase 5): Designed to improve the rate of force production of the core musculature and prepare an individual to dynamically stabilize and generate force at more functionally applicable speeds. Examples: rotation chest pass, ball medicine ball pullover throw, front MB oblique throw, soccer throw NASM Study Guide - fittinpretty.com 55 Chapter 10 What to Know: Balance Training Concepts: Figure 10.2 Effects of joint dysfunction Table 10.1 Balance training parameters OPT Level (adaptation): Stabilization, Strength, or Power o Be familiar with all exercises listed, as well as how to regress and progress the exercises listed Type of Exercise: Balance Table 10.2 Balance training program design Balance: when the body is in equilibrium and stationary, meaning no linear or angular movement. Requires optimal muscular balance (length-tension relationships and force-couple relationships), joint dynamics (arthrokinematics), and neuromuscular efficiency, using visual, vestibular (inner ear) and proprioceptive inputs. Dynamic balance: the ability to move and change directions under various conditions (ie running on uneven surfaces) without falling. Limit of stability: the distance outside of the base of support that an individual can move into without losing control of his or her center of gravity. Balance training programs that are performed for at least 10 minutes a day, 3 times a week for 4 weeks appear to improve both static and dynamic balance ability. Goal of balance training: to increase the client’s awareness of his or her limit of stability (or kinesthetic awareness) by creating controlled instability. Balance and neuromuscular efficiency are improved through repetitive exposure to a variety of multisensory conditions. Balance progressions: easy to hard, simple to complex, stable to unstable, static to dynamic, slow to fast, two arms/legs to single-arm/leg, eyes open to eyes closed, known to unknown (cognitive task) Progression tools: floor, balance beam, half foam roll, foam pad, balance disc, wobble board, bosu ball 3 levels of balance training: NASM Study Guide - fittinpretty.com 56 1. Balance-stabilization (Phase 1): Designed to improve reflexive (automatic) joint stabilization contractions to increase joint stability. Involve little joint motion. Body is placed in unstable environments so it learns how to react. 2. Examples: single-leg…balance, balance reach, hip internal/external rotation, lift and chop, throw and catch Balance-strength (Phase 2, 3, 4): Designed to improve neuromuscular efficiency. Involve dynamic eccentric and concentric movement of the balance leg, through full ROM. Movements require dynamic control in mid-range of motion, with isometric stabilization at the end-range of motion. 3. Examples: single-leg squat, single-leg squat touchdown, single-leg Romanian deadlift, multiplanar step-up to balance, multiplanar lunge to balance Balance-power (Phase 5): Designed to develop proper deceleration ability to move the body from a dynamic state to a controlled stationary position, as well as high levels of eccentric strength, dynamic neuromuscular efficiency, and reactive joint stabilization. Examples: multiplanar…hop with stabilization, single-leg box hop- up/down with stabilization NASM Study Guide - fittinpretty.com 57 Chapter 11 What to Know: Plyometric Training Concepts: Know all definitions throughout the chapter Integrated performance paradigm The phases of Plyometric Exercise Figure 11.2 Program design parameters for reactive training OPT™ Level (adaptation): Stabilization, Strength, or Power (be familiar with all exercises listed, as well as how to regress and progress the exercises listed) Type of Exercise: Balance Table 11.1 Plyometric training program design Rate of Force Production: Ability of muscles to exert maximal force output in a minimal amount of time. Plyometric (reactive training): Exercises that generate quick, powerful movements involving an explosive concentric muscle contraction preceded by an eccentric muscle action. Individuals react to the ground surface to develop larger than normal ground forces that can be used to project the body with greater velocity or speed of movement. Reaction stimulus: the opposing objects clients encounter during plyometric training (the ground, typically) Integrated performance paradigm: To move with efficiency, forces must be dampened (eccentrically), stabilized (isometrically), and then accelerated (concentrically) 3 phases of plyometric exercise: 1. Eccentric phase: cocking/loading phase, as in squatting before shooting a basket. Potential energy is stored like stretching a rubber band. 2. Amortization phase: dynamic stabilization, transition phase, muscle switches from overcoming force to imparting force in the intended direction. The fast this transition happens, the more powerful the final movement. 3. Concentric phase: unloading phase, concentric action resulting in enhanced muscular performance. NASM Study Guide - fittinpretty.com 58 Purpose of plyometric exercise: Enhances the excitability, sensitivity, and reactivity of the neuromuscular system, increases the rate of force production (power), motor unit recruitment, firing frequency, and motor unit synchronization. Only to be incorporated once client has achieved strength base, proper core strength, and balance. Provides the ability to train specific movement patterns at a more functionally appropriate speed. Goal of plyometric training: decrease the reaction time of the muscle action spectrum (eccentric deceleration, isometric stabilization, and concentric acceleration) Stretch-shortening cycles: eccentric and concentric contractions repeated as a series. Speed of muscular exertion is limited by neuromuscular coordination. Ie: the body will only move within a range of speed that the nervous system has been programmed to allow. 3 levels of plyometric training: 4. Plyometric stabilization (Phase 1): Designed to establish optimal landing mechanics, postural alignment, and reactive neuromuscular efficiency (coordination during dynamic movement). Involve little joint motion. 5. Examples: squat jump, box jump-up/down, and multiplanar jump, all with stabilization at the end Plyometric strength (Phase 2, 3, 4): Involve more dynamic eccentric and concentric movement through a full ROM. Progressed specificity, speed, and neural demand. Designed to improve dynamic joint stabilization, eccentric strength, rate of force production, and neuromuscular efficiency. Exercises performed in a repetitive fashion, with short periods of time on the ground between actions. 6. Examples: squat jump, tuck jump, butt kick, power step-up Plyometric power (Phase 5): Designed to further improve rate of force production, reactive strength, dynamic neuromuscular efficiency, and optimal force production. Involve entire muscle action spectrum and contraction-velocity spectrum used during integrated, functional movements. To be performed as fast and explosively as possible. Examples: ice skaters, single-leg power step-up, proprioceptive plyometrics NASM Study Guide - fittinpretty.com 59 Chapter 12 What to Know: Speed, Agility, and Quickness Training: Know all definitions throughout the chapter Table 12.1 Kinetic Chain checkpoints during running movements- pay attention to the foot/ankle complex Table 12.2 SAQ Program Design Speed: Ability to move the body in one intended direction as fast as possible. Product of stride rate and stride length. (Referring to straight ahead speed, or distance covered divided by time.) Stride rate: # strides taken in a given amount of time (or distance) Stride length: distance covered in one stride, while running Agility: Ability to start, stop, or change direction quickly while maintaining proper posture. Referring to short bursts of movement that involve a change in movement direction, cadence, or speed. Quickness: ability to react to a stimulus and appropriately change the motion of the body with maximal rate of force production. Frontside mechanics: Triple flexion of the ankle, knee, and hip in appropriate synchrony. Proper alignment of the lead leg and pelvis during sprinting, which includes ankle dorsiflexion, knee flexion, hip flexion, and neutral pelvis. Associated with better stability, less braking forces, and increased forward driving forces. Backside mechanics: triple extension of the ankle, knee, and hip in appropriate synchrony. Proper alignment of the rear leg and pelvis, including ankle plantarflexion, knee extension, hip extension, and neutral pelvis. Associated with stronger push phase, including hip-knee extension, gluteal contraction, and backside arm drive. SAQ training benefits: weight loss, coordination, movement proficiency, and injury prevention. Fun and invigorating, increasing exercise compliance, adherence, and effectiveness. When using SAQ for weight loss, clients’ heart rate must be kept appropriate elevated. Examples of SAQ exercises for… NASM Study Guide - fittinpretty.com 60 Youths: Red light, green light and follow the snake (follow the pattern of a rope, one foot on each side, forward and backward) Weight-loss population: jump rope, cone shuffles, ladder drills, box drill, partner mirror drill Seniors: cone/hurdle step-overs, stand-up to figure 8 3 levels of SAQ training 1. Stabilization (Phase 1): 4-6 drills with limited horizontal inertia and unpredictability. Examples: cone shuffles, agility ladder drills 2. Strength (Phase 2, 3, 4): 6-8 drills with greater horizontal inertia but limited unpredictability. Examples: T-drill, box drill, stand up to figure 8 3. Power (Phase 5): 6-10 drills with max horizontal inertia and unpredictability. Examples: modified box drill, partner mirror drill, timed drills NASM Study Guide - fittinpretty.com 61 Chapter 13 What to Know: Resistance Training Concepts: General Adaptation Syndrome Table 13.1 Adaptive benefits of resistance training Table 13.2 The general adaptation syndrome SAID Principle Adaptations for resistance training Table 13.3 Resistance training systems Table 13.4 Peripheral heart action system On the exam, some questions may ask about how to properly progress body position during an exercise. You need to be able to progress (make more difficult), or regress (make easier) a client's body position. Below, progressions are listed from easy to difficult and you can see that two-legs on a stable surface (the floor) is easier than standing on one leg (single-leg), on the floor. With the arms, start a client with two arms, before progressing on to an alternating arm, and then to a single arm exercise. For example: What would be the immediate progression of a “Single-Leg Dumbbell Curl”? a. single-leg, alternating arm, stable b. single-leg, single-arm, stable c. two-leg, alternating arm, unstable d. two-leg, single-arm, unstable General Adaption Syndrome (GAS): Describes how the body responds and adapts to stress. 3 Stages of Response to Stress: 1. Alarm reaction—initial reaction to stressor such as increased oxygen and blood supply to necessary areas of the body 2. Resistance Development—increased functional capacity to adapt to stressor such as increasing motor unit recruitment 3. Exhaustion—a prolonged intolerable stressor produces fatigue and leads to a breakdown in the system or injury (such as stress fractures, muscle strains, joint pain, or emotional fatigue) NASM Study Guide - fittinpretty.com 62 Delayed-Onset Muscle Soreness: Pain or discomfort often felt 24 to 72 hours after intense exercise or unaccustomed physical activity SAID (Principle of Specificity or Specific Adaption to Imposed Demands): Principle that states that the body will adapt to the specific demands that are placed on it. Mechanical specificity: weight and movements placed on the body. Neuromuscular specificity: speed of contraction and exercise selection. Metabolic specificity: the energy demand placed on the body. Mechanically, the body burns more calories when movements are performed while standing and using moderate weights. Neuromuscularly, the body burns more calories when more muscles are being used for longer periods in controlled, unstable environments. Metabolically, the body burns more calories when rest periods are short to minimize full recuperation. Weight loss programs: apply all 3! Adaptions from Resistance Training Stabilization: the body’s ability to provide optimal dynamic joint support to maintain correct posture during all movements. Requires high levels of muscular endurance. Improved by training in controlled, unstable environments. Total Body STABILIZATION EXERCISE EXAMPLES Chest Back Shoulder Biceps Ball squat, curl to press Ball dumbbell chest press Standing cable row Single-leg dumbbell scaption Step-up balance, curl, to overhead press Push-up Ball dumbbell row Seated stability ball military press Triceps Single-leg Supine dumbbell ball curl dumbbell triceps extension Single-leg Prone barbell ball curl dumbbell triceps extension Legs Ball squat Multiplanar step-up to balance Muscular endurance: the ability to produce and maintain force production for prolonged periods NASM Study Guide - fittinpretty.com 63 of time. Helps to increase core and joint stabilization, which is the foundation on which hypertrophy, strength, and power are build. Muscular hypertrophy: the enlargement of skeletal muscle fibers (resulting from an increase in myofibril proteins or myofilaments) in response to being recruited to develop increased levels of tension, as seen in resistance training. Hypertrophy can be achieved through low to intermediate repetition ranges with progressively higher loads. Strength: the ability of the neuromuscular system to produce internal tension to overcome an external force. Needs to be thought of not as a function of muscle, but as a result of activating the neuromuscular system. STRENGTH EXERCISE EXAMPLES Total Body Chest Back Shoulder Biceps Triceps Legs Lunge to two-arm dumbbell press Flat dumbbell chest press Seated cable row Seated dumbbell shoulder press Cable pushdown Leg press Squat, curl, to two-arm press Barbell bench press Seated lat pulldown Seated shoulder press machine Supine bench barbell triceps extension Barbell squat Seated two-arm dumbbell biceps curl Biceps curl machine Stabilization training is designed with the characteristics of type I slow-twitch muscle fibers in mind (slow-contracting, low tension output, and resistance to fatigue), strength training is designed to match the characteristics of type II muscle fibers (quick-contracting, high tension output, prone to fatigue). Majority of strength increases occur during the first 12 weeks of training, from increased neural recruitment and muscle hypertrophy. Power: the ability of the neuromuscular system to produce the greatest possible force in the shortest possible time (force X velocity). Focus: getting the neuromuscular system to generate force as quickly as possible (rate of force production). Increase in power achieved by increasing force (weight) or velocity (speed). To maximize training, heavy and light weights should be used. Modern training programs: emphasis on appropriate exercise selection, all muscle actions, multiple plains of motion, and repetition tempos. NASM Study Guide - fittinpretty.com 64 POWER EXERCISE EXAMPLES Total Body Chest Back Shoulder Biceps Two-arm push press Two-arm medicine ball chest pass Medicine ball pullover throw Barbell clean Rotation chest pass Soccer throw Front medicine ball oblique throw Overhead medicine ball throw Triceps Legs Squat jump __ __ __ __ Tuck jump Resistance Training Systems Single-Set System: 1 set per exercise. Beneficial for beginning clients or maintenance. Multiple Set: multiple sets for each exercise. Superior to single-set for advanced clients. Pyramid: progressive or regressive step approach that either increases or decreases weight with each set. 10-12 reps light to 1-2 reps heavy. Superset: two exercises performed in rapid succession. 8-12 reps with no rest. Variations: A) Two exercises for the same muscle group back to back. (Ex: bench press to push-ups.) This method improves muscular endurance and hypertrophy. B) Two exercises back to back that involve antagonist muscle groups. (Ex: Chest and back or quads and hamstring.) Drop-sets: performing a set to failure, then removing a small percentage of the load, and continuing with the set, completing a small number of reps (2-4). Triple drop: a set to failure followed by 3 successive load decrements performed with no rest. Circuit-training System: a series of exercises performed one after another, with minimal rest between each exercise. Typically low to moderate number of sets (1-3) with moderate to high reps (820) and short rest periods (15-60 sec). Great for those with limited time who want to change their bodies quickly. NASM Study Guide - fittinpretty.com 65 Peripheral Heart Action System: Alternates upper and lower body exercises throughout the circuit. Distributes blood flow between extremities, potentially improving circulation. Split-routine System: breaking the body into parts to be trained on separate days. (Ex: 3-day—M: chest, shoulders, triceps—W: Legs—F: back, biceps) Vertical Loading: progressing a workout vertically down the template by alternating body parts trained from set to set. Allows for maximal recovery for each body part. Order: 1. 2. 3. 4. 5. 6. 7. Total body exercise Chest Back Shoulders Biceps Triceps Legs Horizontal Loading: performing all sets of an exercise or body part before moving on to the next exercise or body part. (Ex: 3 sets of chest, then 3 sets of back, etc. following the order above.) Appropriate for maximal strength and power training. Longer rest periods between sets (takes longer overall). NASM Study Guide - fittinpretty.com 66 Chapter 14 What to Know: Integrated Program Design and the Optimum Performance Training (OPT) Model Know all definitions throughout the chapter. Tempo controls the amount of time that the muscle is active or producing tension – concentrically, isometrically, and/or eccentrically. NASM writes tempos this way: “a/b/c” and tempo is always written in this way: a = eccentric b = isometric c = concentric Therefore, assuming the above, a 4/2/1 tempo on a one repetition of a bench press would be: 4 counts, controlled, eccentric deceleration, bringing the weight back down (before the push) 2 counts on the isometric stabilization at the bottom of the exercise 1 count on the push (upward) Another example: a 2/0/2 tempo on one repetition of a bench press would be: 2 counts, controlled, eccentric deceleration, bring the weight down (into position, before the push upward) 0 no counts of isometric stabilization at the bottom 2 counts of concentric pushing (upward) Focus on the following tables from Chapter 14: Table 14.2 Training volume adaptations Table 14.7 Phase 1: Stabilization Endurance Training (all of the resistance training acute variable and tempo for core) Table 14.8 Phase 2: Strength Endurance Training (all of the resistance training acute variable and tempo for core) Table 14.9 Phase 3: Hypertrophy Training NASM Study Guide - fittinpretty.com 67 (all of the resistance training acute variable and tempo for core) Table 14.10 Phase 4: Maximal Strength Training (all of the resistance training acute variable and tempo for core) Table 14.11 Phase 5: Power (all of the resistance training acute variable and tempo for core) Program design: creating a purposeful system or plan to achieve a specific goal. Acute variables: important components that specify how each exercise is to be performed. They include: Repetition: one complete movement of a particular exercise. Most involve three muscle actions: concentric (against resistance), isometric, and eccentric (with resistance). Set: group of consecutive repetitions. Training intensity: an individual’s level of effort compared with their max effort. Intensity can be increased in a number of ways, such as adding instability. Repetition tempo: speed with which each repetition is performed, from slow to fast/explosive. Training volume: total amount of work performed within a specified time. Rest interval: Time to recuperate between sets. The shorter the rest intervals, the less ATP and PC will be replenished and consequently less energy available for the next set. Training frequency: number of training sessions in a given period. Optimal: 35X/week. Training duration: timeframe from start to end of workout, OR length of time (in weeks) spent in a phase of training. Exercise selection: process of choosing exercises that allow for optimal achievement of desired adaption. There is an inverse relationship between sets, repetitions, and intensity. General Rep, Set, Intensity, and Rest Recommendations: NASM Study Guide - fittinpretty.com 68 3 kinds of exercises: Single joint: focus on isolating one major muscle group or joint (ex: bicep curls, tricep pushdowns, calf raises) Multijoint: involve two or three joints (ex: squats, lunges, step-ups, chest presses, rows) Total body: include multiple joint movements (ex: step-up balance to overhead press, squat to two-arm press, barbell clean) NASM Study Guide - fittinpretty.com 69 Exercises can and should be progressed to increasingly unstable environments to improve stabilization and training of core stabilization muscles. All exercises can be progressed or regressed in a systematic fashion. Stabilization phase: increase/decrease proprioception Strength phase: increase/decrease volume/load Power phase: increase/decrease speed/load NASM Study Guide - fittinpretty.com 70 Undulating periodization: allowing client to train at varying intensities during the course of a week. Ex: stabilization workout on Monday, strength workout on Wednesday, and power workout on Friday. Macrocycle: the largest training cycle, which covers a year of training (aka an annual plan). Mesocycles: 1-3 month periods within a macrocycle. Microcycles: 1-week plans within mesocycles. The OPT Model Stabilization (Phase 1): Designed to create optimal levels of stabilization strength and postural control. Can be progressed by increasing proprioception, volume, and intensity, and by decreasing rest periods. Usually lasts 4 weeks (as with all phases.) NASM Study Guide - fittinpretty.com 71 Strength Endurance (Phase 2): Increase stabilization endurance, hypertrophy, and strength. Includes use of superset techniques in which a more-stable exercise (such as a bench press) is immediately followed with a stabilization exercise with similar motions (such as a stability ball pushup). Hypertrophy Training (Phase 3): Focus on maximal muscle growth. High levels of volume with minimal rest periods. Maximal Strength Training (Phase 4): Focus on increasing the load placed on the tissues of the body. Improves recruitment of more motor units, rate of force production, and motor unit synchronization. Rest periods may need to increase as clients train with heavier loads. Power (Phase 5): Designed to increase the rate of force production (or speed of muscle contraction). Power = force X velocity. Therefore, an increase in either F or V results in an increase in power. Individuals should train with both heavy and light loads for best results. Training involves combining a strength exercise with a power exercise for each body part (ex: barbell bench press superset with a medicine ball chest pass). OPT Model Applications Body Fat Reduction: Alternate between phases 1 and 2, one phase per month. Workouts 3x week. Increasing Lean Body Mass (Hypertrophy): Alternate between phases as follows: 1-2-3, 2-34, 1-2-3-4, 3-2-1. Workouts 3x week. Improving General Sports Performance: Power + Strength Endurance constant, plus alternate on and off Stabilization each month. NASM Study Guide - fittinpretty.com 72 Chapter 15 What to Know: Introduction to Exercise Modalities: There are no specific study tips for chapter 15, but be sure to be familiar with the different modalities such as: Machines Free weights Bands and rubber tubing Cable Machines Medicine Ball Kettlebell Body weight training TRX suspension training BOSU You will not see very much on the exam for this chapter but it will help you with categorizing exercise for resistance, core, and reactive training. Strength-Training Machines Pros: Less intimidating—safer substitute for free weights Can emphasize certain muscle groups for rehab/bodybuilding purposes Various intensities (load) provided in one weight stack Does not require spotter Provides extra support for special-needs clients (great for elderly) Keeps individual in a fixed plane of motion, which may limit excessive ROMs Cons: Do not allow total-body exercises Movements primarily in one plane, fail to accommodate multijoint movements Do not challenge core stabilization system much NASM Study Guide - fittinpretty.com 73 May not be ideal for improving athletic performance Machines do not fit all body types Expensive (comparably) Inferior to free weights for improving core stability/neuromuscular efficiency Free Weights Pros: Can be used to emphasize certain muscle groups Can improve athletic performance Can challenge core stabilization system May improve dynamic joint stabilization and proprioception Allows individuals to move in multiple planes of motion and use multijoint (complex) movements Cons: May require a spotter May be too difficult for beginning clients Requires multiple dumbbells or barbells to change load Potentially more dangerous Intimidating for some *Should try to progress clients to a proprioceptively challenging environment, like bench press on a stability ball or standing with barbell/weights. Also, can regress from free weights to machines if necessary. Cable Machines Allow similar freedom of movement as free weights, yet do not require a spotter Offer resistance for all body parts Effective for developing stability, muscular endurance, hypertrophy, strength, and power NASM Study Guide - fittinpretty.com 74 Important to align the line of pull of the cable with the line of pull of the muscle being worked Can be effectively used in all phases Can challenge the core Prefer exercises to be done in a standing position Elastic Resistance (Rubber Tubing/Bands) Inexpensive alternative to training with resistance Not ideal for maximal strength training, but helpful for improving muscular strength and endurance Allows movement in multiple planes and often greater ROM compared to machines Allow clients to perform resisted exercises that mimic sports-like movements Can use two bands together as a form of progression, vs. moving to a higher resistance band Problem: the tension changes as the bands are stretched, and stretch properties vary according to thickness, age of the band, and how often they’re used Versatile, cheap, and portable Medicine Balls Oldest means of resistance training Dynamic power opportunities Allows explosive movement without eccentric deceleration Weigh between 1-30 pounds (high-velocity movements require lighter balls) Best for rebound activities such as bouncing/throwing against a wall Kettlebell Training Differs from dumbbells in that center of mass is away from the handle, requiring more strength and coordination Transform dynamic force reduction into powerful force production for a fun, challenging, effective workout NASM Study Guide - fittinpretty.com 75 Leads to enhanced athleticism, coordination, and balance, increased mental focus and physical stamina, increased oxygen uptake, and increased total body conditioning (etc.) Emphasis on posterior chain, working from the ground up and keeping perfect form throughout Particularly appropriate in phases 1, 2, and 5 Body Weight Training Often used for core, balance, and plyometric training Teach clients to train in all planes of motion for greater kinesthetic awareness Most are closed-chain exercises, which lead to greater motor unit activation and synchronization compared to open-chain Portable *Closed-chain Exercises: Distal extremities (hands or feet) are in a fixed position and the force applied by an individual is not enough to overcome resistance (such as the ground or an immovable object). Examples: push-ups, pull-ups, squats. *Open-chain Exercises: Distal extremities (hands or feet) are not in a fixed position and the force applied is great enough to overcome resistance (such as barbells or dumbbells). Examples: bench press, lat pulldown, leg extension machine. Suspension Body-Weight Training Can be easily modified for any client Allow trainers to manipulate body position and stability to provide multiplanar, multijoint exercises in a proprioceptively enriched environment Benefits: increased muscle activation, low compressive loads on spine, increased performance, potential increase in caloric expenditure, improvements in cardio fitness Ideal in phases 1 and 2 of OPT. Proprioceptive Modalities Stability Balls Primarily used to increase demand for stability NASM Study Guide - fittinpretty.com 76 Can also be used to reinforce proper posture during squatting movements Can introduce greater ROMs during certain movements, like crunches Novices with poor balance should master stable exercises first Not recommended for use with max force building exercises Bosu Balls Can be used with either side up (Examples: squat while standing on rounded side, or do push-ups with hands on flat side) Increases demand for stability Safe to stand on Ideal for phases 1, 2, and 5 Vibration Training Beneficial effects on stimulating greater muscle fiber involvement during exercise, leading to greater increases in lean body mass, weight loss, and changes in body composition Performed on a platform that generates vertical sinusoidal vibrations (a smooth repetitive oscillation) that stimulate muscle contractions comparable to the tonic vibration reflex Some benefits: improved circulation, alleviates muscle soreness, increased bone density, potentially reduces symptoms of Parkinsons, etc. NASM Study Guide - fittinpretty.com 77 Chapter 16 What to Know: Chronic Health Conditions and Physical or Functional Limitations For this chapter, read through the text and highlight the training guidelines and have a general idea on how to design a program for the special populations mentioned in this particular chapter. Don't worry too much about the acute variables (reps, sets, tempo, etc.) but rather on contraindications and more appropriate techniques for these populations. Kids How children differ from adults in terms of exercise: Children do not typically exhibit a plateau in oxygen uptake at maximal exercise Children are less efficient and tend to exercise at a higher percentage of their peak oxygen uptake Children do not produce sufficient levels of glycolytic enzymes to be able to sustain bouts of high-intensity exercise Immature thermoregulatory systems mean delayed and limited sweating ability Relatively high peak oxygen uptake levels allow children to perform endurance activities well Program recommendations: 60 min/day Seniors Blood pressure tends to be higher. Arteriosclerosis: normal physiological process of aging that results in arteries that are less elastic, leading to greater resistance to blood flow Atheroscleroris: caused by poor lifestyle choices, restricts blood flow as a result of plaque buildup Peripheral Vascular Disease: plaques that form in any peripheral artery, typically lower leg Blood pressure guidelines: Normal: <120/80 Prehypertensive: 120/80 to 139/89 At risk: 140/90+ NASM Study Guide - fittinpretty.com 78 Recommendations: Use of self-myofascial release and static stretching Stage 1 and II cardio Emphasis on stabilization training Choose exercise modalities that safeguard against falls and foot problems 30-60 min/day or 8-10 min. bouts Progress to free sitting or standing exercises when possible Obesity Currently, 66% of Americans over 20 are overweight. 72 million Americans are obese (34%). Obese people exhibit: worse balance, slower gait velocity, shorter steps Recommendations: Focus on energy expenditure, balance, and proprioceptive training Burn 200-300 calories per workout Use caution in supine and prone positions, due to potential hypotensive/hypertensive responses Standing position might be most comfortable Phases 1 and 2 of OPT most appropriate Emphasize appropriate breathing Dumbbells, cables, and tubing work well over machines 40-60 min/day, 5 days a week Diabetes Diabetes is a metabolic disorder in which the body does not produce enough insulin (type 1) or the body cannot respond normally to the insulin that is made (type 2). Recommendations: Take care when recommending walking to prevent blisters and foot microtrauma Careful about carbohydrate intake and insulin use, before and after exercise Guidelines similar to those for obese people Careful with self-myofascial release, since some have peripheral neuropathy (loss of protective sensation in feet/legs) Phases 1 and 2 of OPT most appropriate Weight-bearing activities may need to be avoided at least initially Be cognizant of signs and symptoms of hypoglycemia NASM Study Guide - fittinpretty.com 79 Intensity no greater than 50-90% in beginning Hypertension Defined as blood pressure over 140/90. Common contributors: smoking, a diet high in fat, and excess weight Plan to reduce blood pressure should include diet, exercise, weight loss, and medication Body position can have an impact on blood pressure—supine and prone positions can increase BP Both hypotensive and hypertensive responses are possible Recommendations: Use static and active stretching Foam rolling might be contraindicated since it involves laying down Core exercises in a standing position preferred over supine core exercises Use plyometric training with care Resistance training in seated or standing positions Use circuit-style or Peripheral Heart Action (PHA) training system to keep blood flow moving Breathe normally Avoid Valsalva maneuver (overgripping) Coronary Heart Disease CHD is caused by atherosclerosis (plaque formation), leading to narrowing of coronary arteries Treatment involves aggressive multidisciplinary lifestyle intervention, including diet, exercise, and stress reduction Cardiovascular complication rate is low Recommendations: Obtain upper safe limit for exercise (heart rate) Clients must be able to monitor own heart rate Use rate of perceived exertion (0-11)/Talk Test to measure intensity Aerobic low-intensity exercise is recommended Do not start resistance training unless client has been exercising for at least 3 months Use circuit-style or Peripheral Heart Action (PHA) training system to keep blood flow moving NASM Study Guide - fittinpretty.com 80 Osteoporosis Osteopenia: a condition in which bone mineral density (BMD) is lower than normal and considered a precursor to osteoporosis Osteoporosis: a disease of bones in which BMD is reduced, bone microstructure is disrupted, a the actual proteins in bone are altered. Commonly affects the neck of the femur and the lumbar vertebrae, placing the core in a weakened state and more susceptible to injury (ie a fracture). Primary osteoporosis: associated with normal aging, attributable to lower production of estrogen/progesterone (involved in regulating bone loss) Secondary: caused by certain medical conditions that disrupt normal bone reformation (alcohol abuse, smoking, certain disease or meds) Peak bone mass: the highest amount of bone mass a person is able to achieve during his lifetime. People must remain active enough to ensure adequate stress is being placed on their bodies to maintain consistent bone remodeling. Individual who participate in resistance training have a higher bone mineral density than those who do not. However, it improves density by no more than 5% (not high enough to prevent fractures). Recommendations: Focus on prevention of falls, rather than strength, for elderly Combine resistance training with flexibility, core, and balance training 50-90% max heart rate Focus exercises on hips, thighs, back, and arms If client cannot get around well, use stable, machine-based equipment Some degenerative postural changes cannot be corrected Take care with crunches or movements with a lot of spinal flexion Plyometric training not recommended Higher intensities (75-85%) needed to stimulate bone formation Min. 6 months of consistent training required to have an effect on bone mass Arthritis Arthritis: an inflammatory condition that mainly affects the joints. An estimates 21.6% of the adult population have arthritis. Osteoarthritis: caused by degeneration of cartilage within joints NASM Study Guide - fittinpretty.com 81 Rheumatoid arthritis: degenerative joint disease in which body’s immune system mistakenly attacks its own tissue. Characterized by morning stiffness and eventual loss of joint integrity. Recommendations: Pain persisting for more than 1 hour is an indication that exercise needs to be modified or eliminated Avoid exercises involving high intensity or high repetitions to avoid joint aggravation Low-volume circuit program or multiple session format is best Steroids can increase fracture risk Individuals have decreased strength/proprioception, decreased ability to balance while standing, loss of knee-extensor strength Symptoms are heightened through inactivity as a result of muscle atrophy and lack of tissue flexibility Cancer Probability for American men is 44%, 38% for women. Benefits of exercise: less fatigue, increased quality of life, positive effects on mood/self-concept, retention of lean body mass Recommendations: Exercise at low to moderate intensities for moderate durations Slowly progress cardio training (5 minutes up to 30) Core and balance exercises essential Plyometrics not recommended until client has progressed to three phase I workouts per week Phase 1 and 2 for resistance training Pregnancy Most recreational pursuits are appropriate. Flexibility and core training are important to maintain posture. Core-stabilization exercises improve strength of pelvic floor. Not advised in 2nd or 3rd trimesters: supine or prone positions, torso twisting movements Pregnant clients prone to dizziness, nausea, fainting. Recommendations: NASM Study Guide - fittinpretty.com 82 Static and active stretching, self-myofascial release as tolerated (esp. on varicose veins or swollen calves) Cardio: stage I (stage II only on doctor’s advice) Plyometric training not recommended beyond first trimester Postpartum women should be encouraged to: reeducate posture, joint alignment, muscle imbalances, stability, motor skills, and recruitment of deep core stabilizers Chronic Lung Disease One of the leading preventable causes of death. Restrictive Lung Disease: the condition of a fibrous lung tissue, which results in a decreased ability to expand the lungs. Chronic Obstructive Lung Disease: condition of altered airflow through the lungs, generally caused by airway obstruction as a result of mucus production. Problems: decreased ventilation and decreased gas exchange ability (leading to decreased aerobic capacity and endurance and in oxygen desaturation). Fatigue, shortness of breath, muscle wasting, hypertrophied neck muscles. Recommendations: Use of lower body cardiorespiratory and resistance training Use Peripheral Heart Action training system 40-60% of peak work capacity, work up to 20-45 min. Maintain adequate rest intervals Intermittent Claudication/Peripheral Arterial Disease Intermittent claudication: manifestation of symptoms caused by peripheral arterial disease (PAD), characterized by limping, lameness, or pain in lower leg Peripheral arterial disease: characterized by narrowing of major arteries that are responsible for supplying blood to the lower extremities Recommendations: Intermittent format of exercise, with rest as necessary. Do not exceed established heart rate upper limit. Focus on aerobics, emphasis on walking, with resistance exercise as complementary Self-myofascial release not recommended NASM Study Guide - fittinpretty.com 83 Phase 1 and 2 suggested Primary limiting factor: leg pain Exercise should induce symptoms, causing a stimulus that increases local circulation NASM Study Guide - fittinpretty.com 84 Chapter 17 What to Know: Nutrition Know all Definitions throughout the chapter Table 17.4 Know all of the Essential Amino Acids Table 17.6 Recommended Protein Intake Daily recommendations for fiber Specific recommendations for endurance athletes Fatty acids Lipids in the body Daily recommendations and importance of water Table 17.11The effects of dehydration Be familiar with guidelines for altering body composition Risks of very low calorie diets Calorie count for proteins, carbohydrates, fats Nutrition: sum of the processes by which an animal or plant takes in and uses food substances for growth and repair of tissues. Calorie: a unit of energy defined as the amount of heat energy required to raise the temperature of 1 gram of water 1 degree Celsius. 1 g of carbohydrates = 4 calories 1 g of fat = 9 calories 1 g protein = 4 calories Total Energy Expenditure (TEE): the amount of energy (calories) spent, on average, in a typical day. Resting Metabolic Rate (RMR): the amount of energy expended while at rest (to sustain bodily functions such as blood circulation, respiration, and temperature regulation). 70% of TEE. Affected by multiple factors, including age, sex, genetics, hormonal changes, body size, body composition, temperature, illness, medication, etc. NASM Study Guide - fittinpretty.com 85 Avoid declines in resting metabolism by avoiding starvation diets. Thermic Effect of Food (TEF): amount of energy expended above RMR as a result of the processing of food (digestion) for storage and use. 6-10% of TEE. Energy expended during physical activity: above RMR and TEF. 20% of TEE. Estimating TEE: 1. Weight (lbs) x 10 = RMR 2. RMR x activity factor (1.2-2.1) = TEE Protein Proteins are primarily responsible for building and repairing body tissues and structures. They are made up of amino acids linked by peptide bonds. Amino acids: 8 essential (needs to come from food), 10 nonessential (created by the body), and 2 semi-essential 3 uses of amino acids (broken down from proteins): protein synthesis (building/repairing tissue), immediate energy, or potential energy (fat storage). Complete proteins: foods that supply all of the essential amino acids in appropriate ratios. Limiting factor of a protein: the essential amino acid that is missing or present in the smallest amount. Synthesis works on an all-or-none principle, and is reduced to the point at which the cell runs out of the limiting amino acid. Biologic value (BV): Term used to rate protein quality. Protein notes: Consuming protein above requirements will not reveal previously untapped muscle-building capacity. Consuming higher quality proteins could lead to needing less protein overall. Incomplete proteins can be combined to create complete proteins. Anaerobic and aerobic exercise affect protein requirements in different ways. Protein intake may be adjusted to aid in satiety. Complete proteins: animal sources, dairy and meats. NASM Study Guide - fittinpretty.com 86 Incomplete proteins: grains, legumes, nuts, seeds, and vegetables. Factors affecting protein requirements: daily exercise and physical activity levels, daily caloric consumption, body composition goals, and sports-performance goals. The goal is to satisfy energy needs with carbohydrates and fat, saving protein for tissue repair and growth. This is why carbs are often referred to as protein sparing. Gluconeogenesis: when amino acids are used to assist in energy production during a negative energy balance. Exercise depletes glycogen, increasing gluconeogenesis. Protein and Bodybuilders Competitive levels of body fat are generally unhealthy and impossible to maintain. Because the body’s survival mode kicks in, continual reductions of calorie intake are necessary to continue to achieve change. Because of its anabolic requirements, protein intake cannot be lowered. Often, protein is increased in the final weeks before a competition. Normal eating habits enable greater muscular gains than year-round high-protein intake. Carbohydrates consumed within an hour after exercise inhibits muscle-protein breakdown. Protein Requirements Skeletal muscle = 72% water, 22% protein, and 6% fat, glycogen, and minerals. 1 lb. of muscle = 100g protein. To build muscle, consume: An additional 200 to 400 calories daily (1.5 to 2.5 calories per pound) above maintenance requirements. AND A little extra protein (2 ounces). General protein recommendations: Sedentary adults 0.8 g (0.4/lb.) Strength athletes 1.2 - 1.7 g (0.5-0.8 g/lb.) Endurance athletes 1.2 - 1.4 g (0.5-0.6 g/lb.) NASM Study Guide - fittinpretty.com 87 Chronic consumption of a high-protein diet is generally associated with a higher intake in saturated fat ad low fiber (risk factors for heart disease). Kidneys have to work harder to eliminate increased urea produced, so be careful with anyone with kidney problems. Also, more protein requires more fluid consumption. Protein requires 7x more water than carbs or fat to metabolize. Main concern with highprotein diets is dehydration. Recommended Dietary Allowance for protein: 0.8 g/kg/day. 10-35% total caloric intake. Carbohydrates Carbohydrates: a chief source of energy for all body functions and muscular exertion, carbs are compounds containing carbon, hydrogen, and oxygen. Generally classified as sugars (simple), starches (complex), and fiber. Carbs provide the body with nutrition fat and protein cannot, satiety, proper cellular fluid balance, blood sugar levels, and spare protein for building muscles. They are the perfect and preferred form of energy. Parts of the central nervous system rely exclusively on carbohydrate. Sugar: any monosaccharide or disaccharide. Simple sugars (such as honey and fruit) are easily digested, double sugars (table sugar) less so, and starches (like whole grain) require the most digestive action. Monosaccharide: single sugar unit. Includes glucose (blood sugar), fructose (fruit sugar), and galactose. Disaccharides: two sugar units. Includes sucrose (common sugar), lactose (milk sugar), and maltose. Starch: the storage form of carbohydrates in plants, comprised of connected monosaccharides. Must be broken down into glucose (simple sugar) for utilization. Glycogen: the storage form of carbohydrates in humans, comprised of connected monosaccharides. Polysaccharides: long chains of monosaccharide units linked together and found in foods that contain starch and fiber. These foods are called complex carbohydrates and include starch found in plants, seeds, and roots. Glycemic index (GI): the rate at which ingested carbohydrate raises blood sugar and its accompanying effect on insulin release. High: > 70 Moderate: 56-69 NASM Study Guide - fittinpretty.com 88 Low: < 55 Foods lower on the GI are good sources of complex carbohydrates, as well as being high in fiber and overall nutritional value. Fiber Fiber is an indigestible carbohydrate. It provides bulk in the diet, increasing satiety, delays emptying of the stomach, prevents constipation, lowers blood cholesterol, regulates the body’s absorption of glucose, and regulates blood glucose levels. Two types: soluble and insoluble. Soluble fiber: moderates blood glucose levels, lowers cholesterol. Examples: oats, legumes, barley, many uncooked fruits/veggies. Insoluble fiber: passes through the digestive system in its original form. Helps reduce risk of colorectal cancer, hemorrhoids, and constipation. Daily diet should include 25 to 38 g of fiber. As duration of exercise increases, available glucose and glycogen diminish, increasing the reliance on fat as a fuel source. “Fat burns in a carbohydrate flame.” Maximal fat utilization cannot occur without sufficient carbohydrate to continue Krebs cycle activity. Carbohydrate intake recommendations General: 6-10 g/kg/day, 45-65% of total caloric intake Before exercise: Consume a high-carb meal 2 to 4 hours before exercising for more than an hour. During exercise: Consume 30-60g of carbohydrate every hour. After exercise: Consume 1.5g per kg of carbohydrate within 30 minutes of completing exercise. For weight loss: there is no need to reduce carbohydrate intake for weight loss. High-carb diets increase the use of glycogen as fuel, whereas a high-fat diet increases the use of fat as fuel. Carb-rich diets will build glycogen stores and aid in performance/recovery. Carbohydrate loading can nearly double muscle glycogen stores, increasing endurance potential. Week-long program includes 4 days of carb depletion (10% of calories) followed by 3 days of rest and a high-carb diet (90% of calories). NASM Study Guide - fittinpretty.com 89 Fatty Acids Lipids: a group of compounds that include triglycerides (fats and oils), phospholipids, and sterols. 95% are fats and oils. Lipids are three fatty acids attached to a glycerol backbone. Monounsaturated fat: Olive oil, canola oil, peanut oil, avocados Polyunsaturated fat: vegetable oils, omega-3 fatty acids (fish), most nuts and seeds Saturated fat: meat, poultry, lard, butter, cheese, cream, eggs, whole milk, tropical oils Trans-fat: stick margarine, shortening, fried foods, fast food, many baked goods Fats are carriers of fat-soluble vitamins A, D, E, and K. Fat intake recommendations: Adults: 20-35% of daily calories Athletes: 20-25% of daily calories No health benefits in consuming less than 15% daily It is metabolically inexpensive to convert dietary fat to body-fat stores. Fat has a lower thermic effect than other macronutrients. Dietary fats stimulate the release of CCK, a hormone that signals satiety. Low-volume, high-calorie diets might not satisfy peripheral satiation mechanisms (chewing, swallowing, stomach distention), leading to hyperphagia (overeating). Fat is digested and absorbed slowly. The body needs fat for energy, structure/membrane function, precursors to hormones, cellular signals, and regulation of uptake/excretion of nutrients in cells. Metabolic syndrome (syndrome X): a cluster of symptoms characterized by obesity, insulin resistance, hypertension, and dyslipidemia. Associated with obesity, high-fat diets, and sedentary lifestyle. In the presence of higher fat levels, the body decreases glycogen synthesis, leading to chronically elevated levels of blood sugar. Water Water constitutes 60% of the adult human body. NASM Study Guide - fittinpretty.com 90 Sedentary men/women should consume 3.0 L (13 cups)/2.2 L (9 cups) per day. Those who want to lose weight should drink an additional 8 ounces of water per 25 pounds above ideal weight. The body cannot adapt to dehydration. Effects of dehydration: Decreased blood volume, blood pressure, sweat rate, performance, cardiac output, and blood flow to skin Increased core temperature, heart rate, perceived exertion, and use of muscle glycogen Water and sodium retention Fluid replacement guidelines: 14-22 oz. of fluid 2 hours before exercise 5-12 oz. of fluid for every 15-20 minutes of exercise 16-24 oz. for every pound of body weight lost after exercise Fluids should be cold for more rapid gastric emptying If exercise exceeds 60 minutes, a sports drink (containing up to 8% carbs) should be used Altering Body Composition For fat loss: Eat less/exercise more Distribute protein, carbs, and fat throughout the day Consume less than 10% of calories from saturated fat 4-6 meals/day 9-13 cups water Weight and measure food for at least first week For lean body mass gain: 4-6 meals/day Spread protein intake throughout the day Ingest protein and carbs within 90 minutes of a workout Do not neglect important of carbs and fat Risks of very low calorie diets: NASM Study Guide - fittinpretty.com 91 (Lower than 1200 calories) Increased risk of malnutrition Poor energy and inability to complete essential fitness A behavioral pendulum swing—inability to reintroduce forbidden foods in a moderate manner Fatigue, constipation, nausea, diarrhea. NASM Study Guide - fittinpretty.com 92 Chapter 18 What to Know: Supplementation Table 18.2 Dietary reference intake terminology Units of measure used on dietary supplement labels Adverse effects of excess for specific vitamins & minerals Be familiar with the ergogenic aids and dosage Dietary supplements: products intended to supplement the diet. Contain some nutrient property, intended for ingestion, labeled as a dietary supplement, and cannot be represented for use as conventional food or approved as a drug. Almost anything that is not already classified as a drug can be put into a pill, capsule, or powder and sold as a dietary supplement. Scientific studies pertaining to the health consequences of multivitamin-mineral supplementation are limited in quantity and quality. Dietary reference intake (DRI) values for nutrients provide good guidelines for what constitutes an adequate intake of a nutrient. Estimated Average Requirement (EAR): Average daily nutrient intake level that is estimated to meet the requirement of half the healthy individuals who are in a particular life stage and gender group. Recommended Dietary Allowance (RDA): Average daily nutrient intake level that is sufficient to meet the nutrient requirement of nearly all (97-98%) of healthy individuals. Adequate Intake (AI): Recommended average daily nutrient intake level, based on observed approximations or estimates of nutrient intake that are assumed to be adequate for a group (or groups) of healthy people. Used when RDA cannot be determined. Tolerable Upper Intake Level (UL): Highest average daily nutrient intake level likely to pose no risk of adverse health effects to almost all individuals. As intake increases above UL, the potential risk of adverse health effects increases. o Safe Upper Limits (SUL): UK version of UL Even essential nutrients are potentially toxic at some level of intake. (Example: excess vitamin A during conception/early pregnancy can lead to birth defects, vitamin D excess can result in the calcification of blood vessels, excessive vitamin B6 intake can cause permanent damage to sensory nerves.) NASM Study Guide - fittinpretty.com 93 Nutrient levels that are appropriate for healthy people can be life-threatening for those with certain conditions. For example, supplementation with vitamins E and K are complicate conditions for people on anticoagulation therapy. Whether optimal is closer to the RDA and AI or the UI for a nutrient is unknown and likely differs for the various nutrients and also may differ from one person to another. Units of measure: Protein, carbs, and fat expressed in grams. Vitamins, minerals, amino acids, and fatty acids expressed in milligrams or micrograms. % DVs for vitamins/minerals are based on the 1968 RDAs for adults (using the higher of two recommended amounts, when there are differences between males and females). DV problem: iron RDA is 18 mg/day, based on a menstruating woman’s requirement. Men’s RDA is 8 mg/day. When a pill provides 100% of DV for iron, it provides more than twice the RDA for a man. International units (UIs): expression for amounts of vitamin A, D, and E on supplement labels. Vitamin and mineral supplements Levels in multivitamins should be 100%, except for: Vitamin A (when indicated as retinol) should be less than 100% DV--high intake of retinol has been linked to hip fracture in older women and birth defects during pregnancy B-carotene: high levels linked to lung cancer in smokers. Calcium: should be at low levels or absent, since amount required would make pill too big to swallow. For best absorption, daily calcium requirements should be spaced throughout the day. Deficiencies and effects: Deficiencies of vitamins/minerals can impair the ability to perform physical activity, and/or mental/emotional problems. Vitamin B12 deficiency is often mistaken for Alzheimer’s disease. It’s not unusual to find supplements with nutrient levels that exceed the UL or SUL values. It is possible to consume excessive amounts of some nutrients without taking a dietary supplement. Nutrients with Greatest Potential for Excess Dosage NASM Study Guide - fittinpretty.com 94 A supplement that contains 100% DV… Vitamin A Contains more than twice the RDA for women, only half the UL and the right amount according to the Guidance Level. Vitamin D Contains twice the AI value. The UL is 5 times the DV, and the SUL is 2.5 times the DV. Iron Contains the RDA for women, more than twice the RDA for men. The UL is only a little over twice the DV, and the Guidance Level is 1 milligram less than the DV. Zinc Contains an amount of zinc that is almost twice the RDA for women. The UL is just a little over twice the DV, and the SUL is a little less than twice the DV. The general population could benefit from the use of a multivitamin. Manufacturing methods and ingredients used could affect results. No one should use multivitamins for medicinal purposes. Ergogenic: work generating. Often used in associated with supplements that enhance athletic performance. Non-nutrient Ergogenic Aids Creatine: synthesized naturally in the body from amino acids, glycine, and arginine. Plays a critical role in normal brain function. Can enhance certain types of brief high-intensity efforts. Typical dosing: 5 to 7 days of supplementation at 20 g per day, followed by a maintenance phase of 2 to 5 g per day. Potentially not safe for those with kidney problems. Creatine loading should be considered no different than carb-loading. Stimulants (caffeine) Caffeine is the most widely used drug in the world. It primarily affects the central nervous system, heart, and skeletal muscles. Caffeine does not seem to help with sprint-type efforts lasting 90 seconds or less. Most effective ergogenic response: 3-6 mg per kg body weight, to be ingested about 1 hour before exercise. Potential negative effects: insomnia, nervousness, nausea, rapid heart and breathing rates, headache, chest pain, and irregular heart rhythm. Banned Stimulants NASM Study Guide - fittinpretty.com 95 50 different stimulants are prohibited in sports. Prohormones: show a lack of benefit and significant risk potential in young to middle-aged athletes. DHEA is produced naturally in the body for most. Some older adults might benefit from DHEA supplementation, although very high levels lead to cancer risk. Androstenedione: a compound that the body can concert to testosterone or estrogen, widely used to boost testosterone levels in men. Androgenic anabolic steroids: drugs designed to mimic the effects of testosterone. Promote the building of muscle mass, strength, and loss of body fat (at the risk of adverse side effects). One particular concern is the early closure of growth plates in bones in youth and stunted development of normal height. NASM Study Guide - fittinpretty.com 96 Chapter 19 What to Know: Lifestyle Modification and Behavioral Coaching: Figure 19.1 Stages of Change Model Know the stages of Change Be familiar with the initial session Effective Communication skills Goal setting- SMART Goals Cognitive Strategies Positive Self talk Exercise Imagery Client Expectations Numerous options Supportive, nurturing environment Convenient locations Affordable cost PTs have 20 seconds to make a good first impression. Stages of Change Stage 1: Precontemplation Clients have no intentions of changing. Strategy: Best strategy is education with attractive, easy-to-read materials. Cannot force clients to form intentions. Stage 2: Contemplation Clients thinking about becoming more active in the next 6 months. Aware of some of the costs/benefits of exercise, but misconceptions might still be present. PTs can have huge influence on this group. Strategy: More education. Discuss ways to deal with perceived cons of exercise. Develop long-term motivational programs. NASM Study Guide - fittinpretty.com 97 Stage 3: Preparation Planning to begin exercising regularly in the next month. Believers in the health benefits of exercise. Unrealistic expectations for change, high risk of disappointment and early dropout. Strategy: Clarify realistic goals/expectations Maintain beliefs in importance of exercise Discuss programs that might work best Consider clients’ schedules, preferences, health concerns Ask about previous successful experiences Avoid exercise that could lead to discomfort or injury Discuss building a social support network Stage 4: Action Clients have started to exercise, but have not yet maintained behavior for 6 months. Strategy: Continue to provide education to strengthen belief in pros of exercise, discuss barriers to exercise, anticipate upcoming disruptions, develop actions for overcoming barriers/disruptions. Stage 5: Maintenance Clients have maintained changes for 6 months or more. Still tempted to return to old habits of less exercise. Strategy: Have a maintenance check-in plan. Give suggestions tailored to personal preference. Assessing Stage What experiences has the client had with physical activity in the past? What worked best/least? What contributed to them quitting? What has kept them from exercising in the past 6 months? What did they do when disruptions (holidays, travel) occurred? Initial Session 20 seconds to make first impression. NASM Study Guide - fittinpretty.com 98 Initial session is for building a relationship—spend at least 30 minutes just talking. Determine client’s readiness to exercise and decide what stage of change he or she is in. Both parties are testing the other, determining whether they want the relationship to continue. Initial conversation points (in addition to assessing the client’s stage): daily activities, importance of physical activity for good health, health concerns (use as a motivator), stress levels, fitness goals, input about what they want included in their exercise program. Important to understand what fitness improvements the client hopes to achieve and to clarify what clients mean by “feeling better, being stronger, looking better, being fit,” etc. SMART goals: specific, measurable (quantifiable), attainable (challenging but not extreme), realistic (client is willing and able), and timely (set goals that can be both attained tomorrow and in 3 months). Break goals down into smaller goals that can be achieved relatively quickly—this is very motivating for clients. 2 types of goals: process and product. Have clients focus on process goals, since they have more control over them. Social facilitation: people increase their effort and performance when others are watching them. Communication It is more important to communicate understanding than to provide the right information. 4 different interpretations of communication: what speaker means, what speaker says, what listener hears, what listener thinks speaker means. Tips: Use open-ended questions to build collaborative relationships with clients. Use reflections, summaries, and affirmations in communication. Genuinely affirm something the client personally values—thoughts, plans, or skills (instead of, say, workout clothes). Change I statements to you statements. Ask permission to give advice to soften the trainer’s role as an authority figure and support a partnership in decision-making. Provide information by giving examples of work with other clients. NASM Study Guide - fittinpretty.com 99 Kinds of support: instrumental (practical factors like childcare), emotional (encouragement), informational (directions, advice), companionship (accountability and camaraderie) Common barriers to exercise: time, unrealistic goals, lack of social support, social physique anxiety, convenience. Positive Self Talk Help clients become aware of negative thought processes by listing any negative thoughts they have around exercise. Come up with a list of positive thoughts they might use in regard to exercise. Train clients to notice negative thoughts, stop them, and replace them with positive ones. Alternatively: generate a list of positive, motivating key words clients can use as awareness tools in pace of negative thoughts. Psyching Up Have clients use techniques they use to get psyched up for other things in life. Positive thoughts, keywords, imagery, specific food, music, etc. Keep a running conversation about whether client is getting psyched up. Exercise Imagery: the process created to produce internalized experiences to support or enhance exercise participation. Have clients visualize themselves performing at the level they desire. Rehearse performances with positive feelings and outcomes. Best to use client’s previous positive experience if one exists. If not, develop one using role models or media influences. Psychological benefits of exercise: promotes positive mood, reduces stress (and related physical symptoms such as headaches and stomachaches), improves sleep, reduces depression/anxiety. NASM Study Guide - fittinpretty.com 100 Chapter 20 What to Know: Developing a Successful Personal Training Business: Providing uncompromising customer service Know who your customers are Ten steps to success 4 P’s of Marketing: Product. Product is the result trying to be achieved. Price. Inevitably, a small percentage of clients will be unable to afford your services. Place (distribution)—channels product/service will go through to reach clients. Examples: online coaching, after school programs, boot camps at parks, corporate wellness programs, sport training centers, senior centers. Promotion—communication of information about product/service. Categorized into push or pull. Advertising pulls consumers in by building awareness, incentives push consumers to purchase in volume. Uncompromising customer service: being unwavering in providing an experience and level of assistance that is rarely, if ever, experienced anywhere else. Develop an obsession for becoming artistic in your approach to helping people. Clients choose PTs based on how they feel when working with them. Guidelines: Take every opportunity to meet/get to know clients. Represent a positive image and high level of professionalism. Never give the impression that a question is inconvenient, unnecessary, or unintelligent. Express ideas well. Obsess on opportunities to create moments that strengthen professional relationships. Take ownership of complaints. Everybody is a potential client. 10 Steps to Success 1. What is the desired annual income? 2. How much must be earned each week to achieve the annual goal?
