Purpose Simple body composition models, such as two-compartment models, employ assumptions which may be violated in specific athletic populations (e.g. the constancy of fat-free mass density [DFFM] and hydration [TBW:FFM]). The present analysis examined FFM characteristics of muscular physique athletes. Methods Twenty-six athletes (16 M: 94.5±9.9 kg, 12.2±4.2 %fat; 10 F: 63.8±5.7 kg, 19.7±4.9 %fat) completed duplicate assessments of dual-energy x-ray absorptiometry (DXA), bioimpedance spectroscopy (BIS), and single- and multi-frequency bioelectrical impedance analysis (SFBIA; MFBIA). FFM was calculated via 5-compartment (5C) model, and FFM characteristics (i.e. DFFM, TBW:FFM, FFM mineral, FFM protein) were compared between sexes and between the sample and reference values (RV) from cadaver analysis. TBWBIS:FFM5C was designated as the reference TBW:FFM model, and alternate models were produced using BIS, MFBIA, SFBIA, impedance-based equations, and DXA output. Results Males had lower TBW:FFM and FFM mineral, but higher FFM protein than females (p
