Lean Muscle Mass Maintenance

Meaning

Lean Muscle Mass Maintenance is the ongoing physiological and clinical effort to preserve the existing skeletal muscle mass and functional strength, thereby counteracting the natural, age-related process of sarcopenia. This is a critical component of longevity medicine, as muscle mass is a primary determinant of metabolic rate, physical resilience, and overall quality of life across the lifespan. The strategy requires continuous vigilance to ensure that muscle protein synthesis rates are balanced with or exceed muscle protein breakdown rates.
