Question

Differentiate aerobics, muscle strengthen, and bone strengthen activities

Answer 1

Aerobic, Muscle-strengthening, and Bone-strengthening Activity

Aerobic activities, also called endurance activities, are physical activities in which people move their large muscles in a rhythmic manner for a sustained period. Running, brisk walking, bicycling, playing basketball, dancing, and swimming are all examples of aerobic activities. Aerobic activity makes a person’s heart beat more rapidly to meet the demands of the body’s movement. Over time, regular aerobic activity makes the heart and cardiovascular system stronger and fitter.

Aerobic physical activity has these components:

• Frequency
• Intensity, or how hard a person works to do the activity. The intensities most often examined are moderate intensity (equivalent in effort to brisk walking) and vigorous intensity (equivalent in effort to running or jogging);
• Duration, or how long a person does an activity in any one session.

Although these components make up a physical activity profile, research has shown that the total amount of physical activity (minutes of moderate-intensity physical activity, for example) is more important for achieving health benefits than is any one component (frequency, intensity, or duration).
