Bioenergetics of Exercise and Training

Human activity, in its various forms, requires energy. Exercise involves the use of energy to perform work that propels the body. Training increases the efficiency of this process in various ways. Bioenergetics is the study of the formation, conversion, and use of energy in a biological system. Its application in sports relates to how three energy systems, (1) adenosine triphosphate (ATP)/creatine phosphate (CP), (2) glycolytic/nonoxidative, and (3) oxidative, are used.

Energy is stored in the body as fat, protein (muscle), and glycogen (liver and muscle). It ...
