Phosphocreatine-Creatine System - Muscles in Exercise

WebPhosphocreatine + ADP ↔ creatine + ATP. ATP formation is favored at the expense of phosphocreatine. This fact explains why the ATP concentration of muscle does not decline during a single contraction: the terminal phosphate group lost from ATP during the contraction is instantly replenished at the expence of phosphocreatine. WebCreatine supplements increase your body's stores of phosphocreatine, which is used to produce new ATP during high-intensity exercise ( 5 ). In fact, just a 6-day creatine load followed by a 2 gram/day maintenance dose can drastically elevate your muscle stores, as shown in the graph below ( 5 , 6 ).
