Principles Of Exercise

Exercise needs vary between individuals because the amount of exercise a person needs depends on many different elements. Personal goals and fitness levels are good examples of this. A person with a high level of physical health will need more intense exercise in order to continue improving their health, and a person with a low level of physical health will need less intense exercise in order to increase their physical health. Higher personal goals also require more dedication than other less difficult goals.

Warming up and cooling down from a workout activity provide many physical benefits, including raising and slowing the heart rate, core temperature, and breathing slowly, which helps to prevent muscle soreness, slows down the heart rate, and minimizes lightheadedness.

Warm-up exercises help to prevent injury and muscle strain, so targeting the area you are focusing should help decrease the risk of injury and muscle strain.

The principle of overload means that exercise programs must increase in difficulty and length because as a person gets stronger and more resilient with exercise, the exercise eventually becomes easy and normal, so the exercise program must get harder in order to remain effective.

specificity, overload, and progression

Intensity has to do with how hard the particular exercise is, while time has to do with the duration of time the exercise is performed. The time spent performing an exercise depends on it intensity, and if an exercise is very intense, it can be done in less time.

time, frequency, and intensity

F-Frequency, how often one works out. I- Intensity, the difficulty level of the workout. T-Time, the duration of the workout. T-Type, what specific workout activity one participates in.

Muscular strength is a measure of how much force a muscle can exert in a single effort, while endurance shows the ability of muscles to be used over time. They develop together, and benefit each other as they grow.

The curl-up test and the arm hang test cannot be used interchangeably because the curl-up test tests the abdominal muscles while the arm hang test tests the strength and endurance of the arm muscles. These are different muscle groups, so they cannot be used interchangeably.

Sustained physical activity allows the body to work its muscles while providing oxygen to the muscle groups. This activity develops the muscle groups in addition to the cardiovascular and respiratory systems that deliver oxygen to the muscles via blood circulation. Sustained physical activity exercises all these systems in concert and improves cardiorespiratory fitness levels.

Exercise uses energy, and when energy expenditure exceeds energy intake, the difference is made up by burning fat. So, improving a person's cardio respiratory fitness and muscular strength and endurance can help improve one's body composition by changing the ratio of body tissue to fat.

There are many types of tests of cardiorespiratory fitness, and these include timed runs, timed walks, and step tests. These different tests test the use of muscle groups and levels of exertion. Running is more difficult than walking, but walking uses different muscle groups, so using multiple, different fitness assessments shows a more complete picture of all the contributing factors that contribute to an individual's level of cardiorespiratory fitness.
