Muscular Power Substrate

Meaning

Muscular Power Substrate refers to the specific biochemical fuel sources and hormonal milieu required for the rapid, high-intensity generation of mechanical force by muscle tissue. This is distinct from endurance fuel; it relies heavily on immediate energy stores like phosphocreatine and glycogen, critically supported by anabolic hormones. Optimizing this substrate is essential for maintaining strength, muscle mass, and high-velocity physical output. It defines the readiness of the neuromuscular unit for explosive action.
