aerobic exercise, any physical exercise that requires additional effort by the heart and lungs to meet the striated muscles’ increased demand for oxygen. Aerobic exercise increases the breathing rate and ultimately raises heart and lung efficiency. Prolonged aerobic exercise (at least 20 minutes five times a week) is recommended for the maintenance of a healthy cardiovascular system. Examples of aerobic exercise include running, jogging, swimming, and vigorous dancing or cycling. Compare anaerobic exercise. See also active exercise, passive exercise.
