Online discussions often describe weaker gym performance as “muscle loss.” Research requires more precise terms: body weight, fat mass, lean mass, skeletal-muscle mass, strength and physical function measure different things.
DXA-derived lean mass includes water and non-fat soft tissue, not only contractile skeletal muscle. Imaging, strength tests and functional assessments answer different questions.
Lower energy intake, reduced body mass, illness, sleep and protein intake may influence performance. A temporary change in a lift does not establish tissue loss.
No. Lean mass is a broader measurement.
Bioimpedance estimates are affected by hydration and require cautious interpretation.
