Relationship of Bioelectrical Impedance Analysis Devices to DXA Percent Fat in College Women Soccer Players

Bioelectrical impedance analysis (BIA) devices are widely used to estimate %fat in women. These devices have proprietary equations embedded in their programming to estimate %fat but have not been widely compared to a standard such as dual-energy X-ray absorptiometry (DXA). The purpose of this study was to evaluate the efficacy of selected BIA devices to track changes in DXA %fat across a season in women soccer players. College players (n = 18) were measured before and after a season for %fat using 4 BIA devices and DXA. Despite high correlations between all BIA devices and DXA (r = 0.82 - 0.88), BIA significantly underestimate %fat by 5.4% to 6.3%. Corrective prediction equations appeared promising to adjust 2 athletic model BIA %fat values to DXA %fat (r = 0.87, SEE = 2.8%). Further evaluation of these new equations should be explored on a larger sample to confirm the current findings.
