DXA-Derived Lean Mass Includes the Fat-Free Component of Adipose Tissue: Impact on Training-Induced Changes in Body Composition

Studies have shown that dual-energy X-ray absorptiometry (DXA)-derived appendicular lean soft tissue mass is highly correlated to both magnetic resonance imaging (MRI) and computed tomography (CT)-derived skeletal muscle mass (1 –4). However, these studies have also found that lower body lean soft tissue mass measured by DXA was greater compared with the skeletal muscle mass measured by MRI or CT (1–4). For example, Chen et al. (1) found a strong association (r = 0.91, p
