WebSep 3, 2024 · The ATP-PC system is responsible for providing energy to the highest threshold muscle fibres that are capable of producing the greatest levels of force. It makes sense that bigger stronger muscles generate more power due to their storage capacity for phosphocreatine. WebAdenosine triphosphate (ATP) is the immediate source of chemical energy for muscle contraction. Since the intramuscular stores of ATP are small (~5 mmol/kg/wet muscle), the ongoing regeneration of ATP is critical for the maintenance of force and power output during sustained exercise.
