Apoio: FAPESP The energy necessary for muscle contraction is obtained from the hydrolysis of ATP, releasing inorganic phosphate. ATP can be furnished by phosphocreatine, glucose, glycogen, amino acids and free fatty acids. The production of ATP is much more efficient in the presence of oxygen than in its absence. The anaerobic metabolism of glucose, although less efficient than the aerobic, represents an important and rapid mechanism of energy generation. Several factors regulate the activity
