Muscle Mass Hormonal Control

Meaning

Muscle mass hormonal control is the complex regulatory network involving endocrine signals that govern the balance between muscle protein synthesis (anabolism) and muscle protein breakdown (catabolism). Key anabolic hormones, including Growth Hormone, Insulin-like Growth Factor-1 (IGF-1), and testosterone, play critical roles in promoting hypertrophy and preventing sarcopenia, the age-related loss of muscle mass. Maintaining the optimal signaling environment is essential for physical function and metabolic health.
