The present study validated the bioelectrical impedance analysis (BIA) method for estimating fat-free mass (FFM). Forty-five male university students served as subjects. Four equations that have been recently proposed for predicting FFM from resistance by BIA and anthropometrical indicators were compared with values obtained from underwater weighing. Cross validation analyses included examination of the constant error (CE), standard error of estimate, r, and total error (TE). The results indicated that the equations Deurenberg et al. (1991), which resulted in small TE and CE values, most accurately estimated FFM.
