FITNESS STUDY GUIDE Health-Related Components of Fitness There are five health-related Components of Fitness. These components are— 1. Muscular Strength—A muscle’s ability to exert force 2. Flexibility—The range of motion of muscles and joints 3. Muscular Endurance—The ability to use a muscle many times without getting tired 4. Cardiovascular Fitness—The ability to exercise the entire body for longer periods of time. 5. Body Composition—The ratio of fat to muscle, bone and other tissues that compose the body. We do NOT test for this at JMS. Four of these health-related Components of Fitness are tested within the JMS Physical Education classes. By using a battery of tests called the Presidential Physical Fitness Challenge, a level of fitness within each category can be measured. This testing battery was instituted by President Eisenhower and has been used since 1957. Activities to improve areas of fitness: Muscle Strength – Strength training, wrestling, football, gymnastics Flexibility – Dance, gymnastics, skating, karate, stretching Muscular endurance – Jump rope, core exercises, distance running Cardiovascular fitness (must be in Target Heart Zone for 20 minutes minimum) – Jogging, aerobics, soccer Body composition – Sound nutritional habits, low intensity activities for an extended period of time The tests included in the Presidential Physical Fitness Challenge include— 1. Mile Run Test—Students run/walk a distance of one mile as quickly as possible. This test measures Cardiovascular Fitness. 2. Sit and Reach Test—Students place their feet on a measurement tool and reach forward as far as possible. This test measures Flexibility. 3. Push Up Test—Students will perform as many 90-degree push ups as possible. This test measures Muscular Strength and Muscular endurance. 4. Curl Ups Test—Students will perform as many curl ups as possible within a one-minute time period. This test measures both Muscular Strength and Muscular Endurance. 5. Shuttle Run—Students will transfer two blocks located 10 yards away past the starting line as quickly as possible. This test measures Agility. Agility is NOT considered a health related Component of Fitness. Benefits of Exercise There are many benefits to exercising. Some of these benefits include— 1. 2. 3. 4. 5. 6. 7. 8. Improved appearance/muscle tone Improved body image Improved overall health Increased level of energy Increased success in your school work or job Helps cope with stress Helps you sleep better Increases life expectancy Three Parts to a Workout 1. Warm Up—Active warm up to raise the core temperature of the body 2. Training/Activity/Exercise—Performance of the activity 3. Cool Down/Stretching—Lowering the core temperature / increase flexibility Are You F.I.T.T.? F = Frequency—How often you exercise I = Intensity—How hard you exercise T = Time—How long you exercise T = Type - What is the exercise HEAR the Benefits of Exercise H—Heart Your heart will be stronger and healthier Heart will resist heart disease You will breathe easier during exercise E—Energy Your energy level will increase to do daily activities Helps you relax and sleep better Avoid feeling sleepy and drowsy throughout the day A—Appearance Improves Muscle Tone Improves body image Helps burn calories and aids in weight control R—Resists Disease Immune system becomes stronger Increases life expectancy Improves overall health Aerobic vs. Anaerobic Exercises are typically identified as aerobic or anaerobic. Aerobic Exercise—Aerobic exercise is any activity that requires the presence of oxygen. These activities are fairly lengthy. Examples include, jogging, biking, swimming, cycling. Aerobic exercise can also be called Cardiovascular Exercise. Anaerobic Exercise—Anaerobic exercise is any activity that is a short burst type that is not affected by oxygen. Examples of anaerobic exercise include sprinting, weight lifting, hitting a baseball/softball. There is usually a break between exercises. Taking Your Pulse While doing cardiovascular/aerobic exercise, it is a good habit to monitor your pulse/heart rate during the activity. There are two places on the body where the pulse can easily be found. One is just off the midline of the throat and the other is on the wrist below the thumb. Always use your fingertips to find your pulse, never your thumb. The heart rate is expressed in beats per minute. Calculating Your Target Heart Rate Zone When doing cardiovascular exercise it is recommended that you keep your pulse within your Target Heart Rate Zone. Steps to calculate your Target Heart Rate Zone— 1. Find your Maximum Heart Rate This is determined by subtracting your age from 220 220 – your age = Maximum Heart Rate 2. Determine the high end (maximum) of your Target Heart Rate Zone This is determined by multiplying your Maximum Heart Rate times 90% Maximum Heart Rate x .90 = Maximum heart rate of THRZ 3. Determine the low end (minimum) of your Target Heart Rate Zone This is determined by multiplying your Maximum Heart Rate times 60% Maximum Heart Rate x .60 = Minimum heart rate of THRZ Stretching Tips Stretching is important for many reasons. Here are a few benefits of proper stretching— 1. Injury Prevention—Increased flexibility will allow body parts and joints to move more freely thus lowering the chance of injury 2. Improved Performance—A flexible joint requires less energy to move 3. Reduced Muscle Soreness—After exercise, stretching can help reduce the soreness the following day A few other pointers about stretching are— 1. 2. 3. 4. Stretching should be static and steady, NOT ballistic or bouncy Stretch to where you can “feel the stretch”, not to pain Hold a stretch for at least 15 seconds Stretch at the end of a workout when the muscles are warm
