Abstract

The present investigation examined the validity of 16 skinfold equations for predicting body density (BD) in youth wrestlers (X age ± SD = 11.0 ± 1.3 yr) by comparing the values to those obtained from underwater weighing. Forty-eight members of youth wrestling clubs (X BD ± SD = 1.0634 ± 0.0125 g.cm-3) volunteered to serve as subjects. The statistical analyses included examination of the constant error (CE), standard error of estimate (SEE), correlation coefficient (r), and total error (TE). The results of this investigation indicated that all of the equations resulted in TE values that were ≥().() 106 g.cm-3(range = 0.0106-0.0229 g.cm-3) which corresponded to ≥4.9% body fat. The TE values were too large to provide accurate estimates of body composition in the present sample of youth wrestlers. Future studies should use the CE values from the present investigation to adjust the intercepts of the skinfold equations in the present study and cross-validate the modified equations on young male athletes.
