Muscle distributor contraction during anaerobic( resistance training ) can use glycogen directly to form ATP. The process is anaerobic glycolysis, meaning it can use the glucose as energy with little oxygen ( 90% glucose, 5% oxygen and distributor 5% fatty acid ). Our muscles store enough ATP for short periods of muscle contraction, when ATP is exhausted it leads to muscle failure. The rest period between weight training sets allows added ATP to be distributor produced and used for muscle contraction. During early stages of aerobic exercise, ATP is again created mainly from glucose until the heart and lungs provide enough oxygen to the muscles to allow fatty acids to be used to create ATP. |

A basic exercises nutritional knowledge tells us that proteins repair and rebuild cells, carbohydrates energize cells and fats provide exercises hormonal foundation for cells. When we lack balance in protein, carbohydrates and fats are bodies adjust and can use all three as a source of fuel for muscle contraction and cellular energy. Though energy is needed for all cellular work, the focus of this article is muscle contraction and body composition. All muscle contraction draws energy from adenosine triphosphate or ATP. |
