Although the two types of exercise–anaerobic and aerobic–sound similar, they are actually quite different–and the controversy over which type of exercise is best continues.
Aerobic literally means in the presence of oxygen. In general, any activity that allows oxygen to release energy through metabolism and that is performed at a low to moderate intensity for more than 90 seconds is usually considered to be an aerobic activity. Because aerobic exercise increases your need for oxygen and requires your heart and lungs to work harder, the benefits of aerobic activity include increased cardiovascular capability and a decrease in body fat. The disadvantages of aerobic activity include a decrease in muscle mass, strength, power, speed and anaerobic capacity. Aerobic exercise is typically longer in duration than anaerobic exercise and involves such activities as running, walking, swimming and cycling.
