Therefore, when you deficiency in an athlete’s diet protein muscles are weak and increases the risk of injury, and lack of calcium can cause convulsions.

The only direct source of energy for muscle contraction is special, the phosphorous compound is adenosine triphosphate. It is also called adenozintrifosfornoy acid, is also widely used shrink — ATP. In the

splitting of ATP is produced adenosine diphosphate (ADP) and releases energy, 20-30% of which goes to the Commission of muscular work, 50-60% is converted into heat, and the remainder is expended on the maintenance of metabolism. So phosphorus Continue reading
