How does Aerobic exercise differ from Anaerobic exercise?
Aerobic means "with oxygen". Oxygen is involved in the metabolic processes that produce energy. Aerobic exercise
can be maintained for long periods, but at a sufficiently low level of intensity.
Aerobic energy metabolism draws on both glycogen and fat. The longer this type of activity is continued,
the greater proportion of fat will be used as fuel.
Anaerobic exercise depends upon energy produced in the absence of oxygen and involves
short bursts of intense effort. This type of exercise is fueled by ATP stored in the muscles
(which lasts only a few seconds) and glycogen.
