Relationship between fat-free mass and body mass.
Open circle, subjects with below 72.4 kg of BM; Open triangle, subjects with above 72.4 kg of BM.

Physical characteristics of validation and cross-validation groups.
Fig 2.
Proportion of segment body composition to whole body composition in fat mass (FM) (A) and fat-free mass (FFM) (B). CON, sedentary males; SOC, soccer athletes; CYC, cyclists; JMP, jumpers; KND, kendo athletes; JD, judo athletes; GYM, gymnasts; THR, throwers.
Fig 3.
Comparison the estimated whole-body fat-free mass (FFM) to the measured FFM in validation group (a), and regression between the measured FFM and the estimated FFM (b), and residual vs. the mean values of the measured and estimated FFM values (c). In panel b, dotted line shows identical line. In panel c, dashed and solid lines indicate the mean values of residual errors and mean ± 1.96 SD, respectively.
