Energy Metabolism and Muscle Fatigue During Exercise
- 187 Downloads
The physiology of exercise is a matter of transforming energy stored in the form of chemical compounds into mechanical energy. Hydrolysis of ATP is the immediate energy source but since the store of ATP is rather small it has to be replenished continuously. The breakdown of ATP to ADP and the rephosphorylation of ADP back to ATP constitutes the ATP-ADP cycle by which the energy consuming processes are coupled to the energy yielding processes (Fig. 1).
