musclemass
Muscle mass refers to the total amount of skeletal muscle tissue in the body. It is a major component of lean body mass and plays a key role in movement, posture, metabolism, and overall strength. Muscle mass can be estimated using imaging or body composition methods such as dual-energy X-ray absorptiometry (DXA), magnetic resonance imaging (MRI), computed tomography (CT), or bioelectrical impedance analysis (BIA). In research and clinical contexts, measurements may focus on whole-body muscle mass or regional measures such as appendicular lean mass.
Muscle mass is influenced by age, sex, hormones, physical activity, nutrition, and genetics. Regular resistance training
Accumulated muscle mass supports physical function, metabolic health, and quality of life. Higher muscle mass is
People can maintain or increase muscle mass through sustained resistance training, adequate protein and calorie intake,
