Cardiorespiratory Fitness is the ability to do vigorous, large muscle exercise over a long period of time. Tests to measure: distance runs, one mile walk, Pacer test. Muscular Strength is the amount of force that can be exerted by a single contraction of the muscle. Muscular Endurance is the ability to continue using certain muscles for a period of time. Tests to measure muscular fitness: curl ups, pull ups, flexed arm hang, push-ups, trunk lift. Flexibility is the ability of a join and a muscle group to move through a range of motion. Tests to measure: back saver sit and reach and shoulder stretch. Body Composition is the percent of body weight composed of fat compared to the percent that is composed of tissue, bone and muscle. Tests to measure: body fat skinfold measurement and BMI.
Cardiovascular Endurance is aerobic conditioning, like jogging, swimming and cycling, can help improve cardiovascular endurance. Muscle Strength exercises is bench press, leg press or bicep curl might be used to measure muscle strength. Muscle Endurance is cycling, step machines and sit up tests are often used to measure muscular endurance. Flexibility can be tested by stretching individual muscles or by performing exercises such as the lunge or the sit and reach. There are several tests that can be used to measure body composition; for example, the most reliable is underwater weighing, but due to the size and expense of the equipment, this type of test isn't common. Many doctors, gyms and health clubs use a pinch test instead.

Heat Exhaustion comes from dehydration and can lead to the potentially fatal heat stroke. When you get too hot the body’s reaction is to sweat for temperature control. Not replenishing these lost fluids properly can lead to more extreme heat exhaustion or even heat stroke. Heat Stroke is where the body’s ability to cool itself by sweating is shut down. All temperature control is removed and the body overheats. Much…
