Prediction techniques are available to estimate %fat in women athletes. The purpose of this study was to determine the accuracy of selected prediction methods compared with dual-energy x-ray absorptiometry (DXA) for estimating %fat. Basketball (n = 29) and soccer (n = 17) players were measured for %fat using two BIA devices and DXA. Soccer players were significantly shorter and lighter but not significantly different in %fat for basketball players. When groups were combined, BIA devices under-predicted DXA %fat by 4.0 to 4.6%, while the two BIA devices were different by only 0.6% (p=0.48). However, %fat values for DXA were significantly higher than both BIA devices in basketball players but not in soccer players. A rank-order correlation (rho = 0.82) indicated that relative position of %fat values was similar between BIA devices. Inexpensive BIA devices provide lower estimated %fat values in women athletes compared to DXA.
