%X Purpose: The purpose of this investigation was to compare a practical measurement of fat free mass index (FFMI) from bioelectrical impedance analysis (BIA) to the dual energy X-ray absorptiometry (DEXA) value in collegiate athletes.
%X Methods: Thirty-three male baseball players and 16 female gymnasts volunteered to participate in this study during their respective pre-season. Subjects visited the laboratory once and had their measurements taken in the following order: weight, height, DEXA, and Omron HBF-500.
%X Results: The BIA device investigated was not a valid estimate of FFMI when compared to the DEXA. The TE was 0.93 kg/ m<sup>2</sup> for males and 0.78 kg/ m<sup>2</sup> for females. There were also significant mean differences between the BIA prediction and the DEXA value for males (BIA=20.6 kg/m<sup>2</sup> vs. DEXA=21.1 kg/m<sup>2</sup>, <italic>P</italic>=0.007) and females (BIA=16.2 kg/m<sup>2</sup> vs. DEXA=17.5 kg/m<sup>2</sup>, <italic>P</italic>=0.001).
%X Conclusions: The BIA device investigated in this study did not provide a valid estimate of FFMI in male and female collegiate athletes. Although there was a general tendency for the BIA to underestimate FFMI compared to DEXA, 98% of the estimates were within plus or minus 2 kg/ m<sup>2</sup>. Therefore, while slightly biased, BIA may provide a reasonable ( 2 kg/ m<sup>2</sup>) estimate of nutritional status for practitioners who are unable able to afford more expensive equipment.
