Lean Muscle Mass Preservation

Meaning

Lean Muscle Mass Preservation is the proactive clinical and physiological goal of maintaining the quantity and quality of skeletal muscle tissue, which is metabolically vital and a primary determinant of physical function and longevity. This process involves counteracting sarcopenia, the inevitable age-related decline in muscle mass, which is often exacerbated by chronic illness, inadequate nutrition, and insufficient mechanical loading. Effective preservation strategies integrate resistance training with optimized protein intake and, where indicated, hormonal balance, to sustain a positive net protein balance. Achieving this preservation is essential for maintaining metabolic health, insulin sensitivity, and independence throughout the lifespan.
