Physical Fitness Health 10 Mr. Behe Physical Fitness •Definition: The ability to perform physical activity and to meet the demands of daily living while being energetic and alert •What are some daily physical activities that you do? Two Types of Exercise: Aerobic vs. Anaerobic • Aerobic – Activity in which large amounts of oxygen are required continually for an extended period of time (30 minutes or more) • ex. Running, biking, swimming for distance, fast walking, jump roping, using a elliptical machine, high impact step climbing • Anaerobic – activity in which the body’s demand for oxygen is greater than what is available during exertion (30 seconds or less) • ex. Weight training, burpees, kettle bell swings, freestyle sprints in the pool (25 yrds), sprinting in track, bench pressing • Increase resistance = muscular strength • Increase repetitions = muscular endurance Aerobic Exercise: •Benefits •Reduce injury •Improve body composition •Improve cardiovascular health •Improve tone, appearance and self-esteem •Myths •Makes you tired •Takes too much time •All exercises give you the same benefits Anaerobic Exercise: •Benefits •Reduce injury •Increase strength in bones, tendons & muscles •Improve tone and appearance •Increase self-esteem •Myths •Decrease flexibility •Reduces coordination 5 Components of Physical Fitness •Cardiorespiratory Endurance •Muscular Strength •Muscular Endurance •Body Composition •Flexibility Benefits of exercise depend on the F.I.T.T. Principle • Frequency – how often (3-5 days a week) • Intensity – how hard (70-85% of Max. HR- Trained Athlete or 50-70%- Untrained) • 220 – your age = Maximum Heart Rate (MHR) • Time – How long (20 – 40 minutes) • Type – What kind (aerobic vs. anaerobic) Work within your target heart rate zone Cardiorespiratory Endurance •Definition: The ability of the heart, lungs and blood vessels to send fuel and oxygen to the bodies tissues during long periods of vigorous activity •Measured by: The 1 mile run/walk, 3minute step test http://link.brightcove.com/services/player/bcpid1418565565?bctid=232 07933001 https://www.youtube.com/watch?v=wL6fJ0QTzhQ Benefits of Cardiorespiratory Endurance • Helps your heart and lungs function more efficiently • Increases your metabolic rate • Increases your number of antioxidants • Improves insulin sensitivity • Improves the muscles ability to use lactic acid • Improves the function of the immune system Benefits (continued) Increases HDLs and decreases LDLs • Decreases chance of colon cancer • Improves psychological well-being • F = 3 x 5 times per week • I = 220-age =(Max HR); x 75% • T = 20 min. or more • T = Aerobic activities (running, biking,…) • https://www.youtube.com/watch?v=JjVsTG5_jU0 Muscular Strength •Definition: The maximum amount of force a muscle can produce in a single effort •Measured by: How much weight you can lift one time Muscular Endurance •Definition: The ability of muscles to work over a long period of time without fatigue •Measured by: Sit-ups, push-ups and pull-ups http://www.youtube.com/watch?v=uO_jfEk-adw Benefits of Muscular Strength and Endurance •Help to perform everyday tasks •Help maintain correct posture •Reduces the risk of being injured •Improves body composition by (+) muscle mass and (-) body fat •Improves self-image •Keeps bones dense and strong Muscle strength and endurance con’t F.I.T.T. Principle F = 2 x 4 times per week I = 8-12 reps, 3 sets more weight = strength more reps = endurance T = 8-12 reps, break between sets T = anaerobic activities resistance exercises Body Composition • Definition: The percentage of fat, lean muscle, connective and supportive tissue • Measured by: Weight charts, Electronic body fat analyzer, skin calipers (more areas measured the better – at least 5), hydro-static weighing • Teen Boys – 10-22% Teen Girls – 15- 27% Chest Belly (abs) Thigh (quad) Triceps Hip Benefits of Good Body Composition •Reduces risk of obesity •Reduces risk of heart disease •Reduces the risk of developing diabetes •Improves appearance and self-image •Reduces the risk of having a stroke •Reduces the risk of developing high blood pressure Body Composition Con’t F = 3 x 5 days per week I = work at target heart rate T = time depends on intensity T = aerobic activities Flexibility •Definition: The ability to move a body part through a full range of motion. •Dynamic stretching is defined as "actively moving a joint through the range of motion required for a sport." •Static stretching refers to holding a stretch with no movement. Benefits of Good Flexibility •Improves quality of life •Prevents and relieves symptoms of arthritis •Prevents injuries to muscles and joints •Improves performance in sports Flexibility •Dynamic Stretch •F = prior to any physical activities •I = between light to moderate effort •T = 5 to 10 minutes •T = aerobic activities Flexibility con’t Static Stretch F = 2 x 3 times per week I = hold each stretch for 30 sec. x 3-5 T = 15 – 30 min. (Hit all major joints) T = Static Stretching -Stretch to a pull is felt and the hold Performance Related Fitness Components •Agility •Balance •Coordination •Power •Reaction Time •Speed Performance Related Fitness Agility – ability to change position of the body rapidly and maintain control Balance – ability to assume or maintain any body position with control and stability Coordination – ability to combine vision or other senses with movements of the body Power – ability to do strength performance quickly, combining factors of strength and speed Reaction Time – Amount of time it takes to get moving once you need to move Speed– time it takes to perform a movement Other Types of Exercise •Isometric – Exercise involving muscular strength with little or no movement of the body part • Example: Pushing against wall •Isotonic – Exercise involving muscular contraction with movement •Examples: Push-ups, pull-ups, weight lifting, etc. Other Types of Exercise Cont. •Isokinetic – Exercise involving muscular strength, muscle endurance and flexibility with movement through an entire range of motion •Examples: Pushing or pulling against a hydraulic lever: Cybex machines, nautilus equipment Principles of Training: Improving the operating efficacy of the body •Overload Principle – Operating at a level above which is normal, thus forcing the body to adapt and function more efficiently •Principle of Progression– Gradually increasing the amounts of exercise to improve your fitness •Principle of Specificity – Different kinds of exercises work on different areas of fitness Need for Physical Activity •Muscle Building •Cardiopulmonary Condition •Sedentary Society •Weight Control •Emotional Release Fitness for Life •Ways to increase physical activity •Daily Routine •Job Related •Formal Act •Warm-up •Exercise •Cool Down •Recreation Fitness for Life Continued •How to Maximize • Benefits of Fitness Success? • Feel better about • Progress slowly yourself • Variety • Blood vessels dilate • Goals • RBC carry more O2 • Lower resting HR • Keep charts • Muscle tone • Safety • Decrease heart • “Buddy System” disease
