Anaerobic Exercise Definition

By

Definition: Exercise in which oxygen is used up more quickly than the body is able to replenish it inside the working muscle. As a result, muscle fibers have to derive their contractile energy from stored substrates like Glygogen (stored carbohydrates), ATP (Adenosine Tri-Phosphate), and CP (Creatine Phosphate). Weight training is an example of such an activity. It is highly anabolic in nature but also highly catabolic if done in excess.
