Aerobic Activity In this kind of physical activity (also called an endurance activity or cardio activity), the body’s large muscles move in a rhythmic manner for a sustained period of time. Brisk walking, running, bicycling, jumping rope, and swimming are all examples. Aerobic activity causes a person’s heart to beat faster than usual. Aerobic physical activity has three components: 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); Frequency, or how often a person does aerobic activity; and 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).
