Micronutrients & recovery
Resistance training induces muscle hypertrophy primarily through increased muscle protein synthesis (MPS) mediated by mTORC1, resulting in a net gain of muscle protein when synthesis exceeds breakdown.
Muscle growth occurs when your body builds more protein than it breaks down. Resistance training triggers this process, and adequate protein intake ensures the raw materials are available to maximize this natural building process.
StrongSupportsVERY_HIGH confidence
Extensive research indicates that an increase in muscle protein synthesis, mediated by the mammalian target of rapamycin complex 1 (mTORC1), plays a crucial, albeit not exclusive, role in the muscle growth resulting from resistance exercise... muscle hypertrophy involves, among other factors, a net gain in muscle protein. This gain occurs when the rate of muscle protein synthesis (MPS) surpasses the rate of muscle protein breakdown (MPB).
