Estimation of body composition in football is an essential component of training. While dual-energy X-ray absorptiometry (DXA) has become the accepted standard for assessing %fat, few prediction equations have been developed using this as the criterion. The study’s purpose was to evaluate the accuracy of skinfold prediction equations derived from DXA for use on college football. Division II players (n = 90) were assessed for DXA %fat and 9 skinfold measurements to predict %fat from 3 equations in the literature. Repeated-measures ANOVA indicated that the non-specific athlete equation significantly over predicted %fat by only 0.9 ± 2.8% while 2 football-specific equations significantly under predicted %fat by -2.3 ± 3.7% and -4.4 ±3.1%, respectively. Absolute difference between predicted and actual %fat for the nonspecific equation was 2.2 ± 2.8%, well within the accepted 3% measurement error. Care should be taken when selecting equations to predict %fat to ensure accurate estimations.
