Introduction: There are multiple methods of assessing body composition. The purpose of this study was to evaluate different body composition methods (i.e., Bod Pod, DXA and BIS) in college football players who were preparing for the NFL Combine.
Methods: College football players (mean ± SD: 22.5 ±1.0 yr.; 184.7 ± 8.3 cm height; 101.7 ± 15.3 kg body weight) came to the laboratory for body composition assessment via dual-energy X-ray absorptiometry (DXA), Bod Pod and bioimpedance spectroscopy (BIS). In addition, total body water (TBW) was measured via BIS (Impedimed).
Results: There no significant differences in measures of lean body mass (LBM) (p=0.1314), fat mass (FM) (p=0.2772) or percentage body fat (BF%) (p=0.3816) between the three methods.
Conclusions: There were no significant differences between the DXA, Bod Pod or BIS vis a vis LBM, FM or BF%. Thus at least for group measures, all are feasible methods for assessing body composition.
