MuscleHypertrophy

Meaning

Muscle Hypertrophy is the scientific term for the increase in the size of individual muscle fibers, leading to a measurable increase in overall muscle mass and cross-sectional area. This physiological adaptation is a direct result of increased protein synthesis exceeding protein degradation, typically stimulated by mechanical tension, metabolic stress, and adequate hormonal signaling. In the context of hormonal health, anabolic hormones like testosterone and growth hormone are potent drivers of this process, which is critical for maintaining strength, metabolic health, and functional longevity. It represents a fundamental anabolic response to external stimuli.
