Exercise of relatively low intensity and long duration, which uses large muscle groups and depends on the aerobic energy system. As exercise intensity decreases and duration increases, fat becomes more important as a fuel. Aerobic exercise increases the body's demand for oxygen, thereby adding to the workload of the heart and lungs, and raising the heart rate. Such exercise, if performed regularly over a period of months or years, strengthens the cardiovascular system and helps develop aerobic endurance. Aerobic exercises include walking, jogging, swimming, cycling, and cross-country skiing.
