2.7. Body Composition Assessment
FM
Body composition (fat-free mass (FFM), fat mass (FM)) was measured by dual-energy X-ray absorptiometry (DXA) with the use of a Lunar Prodigy DXA (GE Medical Systems, Chicago, IL, USA). The in vivo coefficients of variation (CVs) were 0.89% and 0.48% for whole-body fat (FM) and FFM, respectively. Visceral adipose tissue volume was estimated using a constant correction factor (0.94 g/cm
