Physiological Hypertrophy

Meaning

Physiological hypertrophy is the adaptive, beneficial enlargement of an organ or tissue, such as the myocardium or skeletal muscle, that occurs in direct response to increased, sustained functional demand, without any accompanying pathological cellular damage or interstitial fibrosis. This positive remodeling is fundamentally characterized by an organized increase in functional cellular components and a maintained or improved overall functional capacity of the tissue. It represents a healthy, homeostatic response to stimuli like consistent resistance exercise or specific hormonal signaling, ultimately contributing to enhanced systemic performance.
