Muscle Development

Meaning

Muscle development is the complex physiological process encompassing muscle hypertrophy, which is the increase in the size of individual muscle fibers, and the qualitative improvement in muscle strength and function. This adaptive process is fundamentally regulated by a confluence of mechanical stimuli, adequate nutritional intake, and potent anabolic hormones, including testosterone, growth hormone, and insulin-like growth factor-1 (IGF-1). Optimizing muscle development is central to metabolic health, physical performance, and overall longevity.
