Muscle Mass Metrics

Meaning

Objective, quantitative measurements used to assess the total amount and quality of skeletal muscle tissue in the body, which serve as a critical indicator of metabolic health, physical function, and biological aging. These metrics, such as lean body mass index, appendicular skeletal muscle mass, or muscle quality scores, provide tangible data for tracking the efficacy of exercise and hormonal optimization strategies. Maintaining healthy muscle mass is essential for longevity and preventing sarcopenia.
