There are two distinct types of metabolism: Aerobic with (or in the presence of) oxygen and Anaerobic without the presence of oxygen. Even sitting and reading a book is considered to be aerobic activity because aerobic simply means any activity where the oxygen supply is equal to the demand. Anaerobic activity is without oxygen and can only be maintained for a short period of time.
There are three energy systems that contribute to the total energy needs of the body during physical activity:
Phosphagen System - high intensity, very short duration activities for only about 10 seconds of all out exertion.
Anaerobic Glycolysis System high intensity, short duration activities between 1-3 minutes of intense activity beyond the phosphagen system.
Aerobic System lower intensity, longer duration and steady state activities.
