What to Know About Exercise and Health-Related Fitness
There are five components of health- related fitness: 1. Cardiorespiratory endurance is the ability of the circulatory and respiratory systems to supply oxygen during sustained physical activity. 2. Flexibility is the ability to bend and move the joints through the full range of motion. 3. Muscular strength is the maximum amount of force a muscle can produce in a single effort. Click the mouse button or press the space bar to display information.

4. Muscular endurance is the ability of the muscle to continue to perform without fatigue. 5. Healthful body composition is the ratio of lean body mass to body fat. Click the mouse button or press the space bar to display information.

Exercise is planned, structured, and repetitive bodily movement done to improve or maintain one or more components of physical fitness. There are five kinds of exercises: aerobic, anaerobic, isometric, isotonic, and isokinetic. Click the mouse button or press the space bar to display information.

Aerobic exercise Aerobic exercise is an exercise in which large amounts of oxygen are required continually for an extended period of time. Anaerobic exercise Anaerobic exercise is an exercise in which the body’s demand for oxygen is greater than what is available during exertion. Click the mouse button or press the space bar to display information.

Isometric exercise An isometric exercise is an exercise in which a muscle is tightened for about 5–8 seconds and there is no body movement. Isotonic exercise An isotonic exercise is an exercise in which a muscle or muscles move against a resistance weight and/or gravity 8–15 times. Click the mouse button or press the space bar to display information.

Healthful aging Healthful aging also is promoted because physical activities that promote cardiorespiratory endurance activate antioxidants. Antioxidants are substances that protect cells from being damaged and also tie up free radicals, which are highly reactive compounds that can damage body cells and are believed to be one cause of aging. Click the mouse button or press the space bar to display information.

Insulin sensitivity Cardiorespiratory endurance also improves insulin sensitivity, which helps with the metabolism of carbohydrates, fats, and proteins, and lowers the risk of developing diabetes. Click the mouse button or press the space bar to display information.

Alarm stage of GAS General adaptation syndrome (GAS) is a series of body changes that result from stress. Cardiorespiratory endurance reduces the harmful effects of the alarm stage of the GAS. Physical activities help prevent too much of two hormones, epinephrine and cortisolare, from being released in the bloodstream during the alarm stage of the GAS. Click the mouse button or press the space bar to display information.

Ability of muscles Cardiorespiratory endurance improves the ability of muscles to avoid lactic acid buildup, which is one of the factors that causes cramps. Physical activities that promote cardiorespiratory endurance lengthen the time people can exercise without feeling fatigue or cramping. Click the mouse button or press the space bar to display information.

HDLs Physical activities that promote cardiorespiratory endurance increase the number of high-density lipoproteins (HDLs) and decrease the number of low-density lipoproteins (LDLs). This reduces the risk of developing cardiovascular diseases. Click the mouse button or press the space bar to display information.

Immune system Cardiorespiratory endurance improves the function of the immune system. Movement of food Physical activities that promote cardiorespiratory endurance speed the movement of food through the gastrointestinal tract. Click the mouse button or press the space bar to display information.

A fast time and a low heart rate are desirable. Click the mouse button or press the space bar to display information.

The FITT Formula The FITT formula is a formula in which each letter represents a factor for determining how to obtain fitness benefits from physical activity. Frequency is how often you will perform physical activities. You should participate in physical activity three to five days a week. Less frequent activity will not produce fitness benefits, and more might stress your immune system and lead to injury. Intensity is how hard you will perform physical activities. Click the mouse button or press the space bar to display information.

The FITT Formula The FITT formula is a formula in which each letter represents a factor for determining how to obtain fitness benefits from physical activity. Time is how long you will perform physical activities. The length of time you perform physical activity will depend on the intensity. Type is the kind of physical activities you will perform to develop fitness. Click the mouse button or press the space bar to display information.

Flexibility Flexibility is the ability to bend and move the joints through the full range of motion. A measure of your flexibility is your ability to move your joints through their natural range of motion. Click the mouse button or press the space bar to display information.

What to Know About Flexibility
What are the benefits of flexibility? Flexibility helps improve quality of life, decreases the likelihood of having accidents, and it helps prevent lower back pain and injuries to muscles and joints. How does one develop flexibility? Follow the FITT formula to improve flexibility. For Frequency, perform stretching exercises two to three times a week and as part of your warm-up and cooldown. Click the mouse button or press the space bar to display information.

For Intensity, hold each stretch for 15–30 seconds, repeating each stretching exercise three to five times. For Time, include exercises to stretch the muscles that work each of the major joints in the body. For Type, you should understand that there are two techniques for stretching muscles that move joints: static stretching and ballistic stretching. Click the mouse button or press the space bar to display information.

Static stretching is stretching the muscle to the point where a pull is felt and holding the stretch for 15–30 seconds. Ballistic stretching is rapidly stretching the muscle with a bouncing movement. Fitness experts warn against ballistic stretching because it may cause injuries. Stretching should be a slow and gentle movement. Click the mouse button or press the space bar to display information.

What test is used to measure flexibility? Several tests measure flexibility, including the V-sit reach test which assesses flexibility by measuring how far you can lean forward. Do I need to warm up and cool down when I do stretching exercises? Warming up increases blood flow to muscles to get them ready for more work. A cooldown helps to improve circulation and keeps you from being sore. Click the mouse button or press the space bar to display information.
