Background. This ­study was ­designed to ­assess the valid­ity of pre­vi­ous­ly-devel­oped anthro­po­met­ric regres­sion equa­tions in deter­mi­na­tion of per­cent ­body fat in col­le­giate wres­tlers (N=22).
Methods. Means (M) stan­dard devi­a­tions (SD), cor­re­la­tion coef­fi­cients®, stan­dard ­errors of esti­mate (SEE) and ­total ­errors (TE) ­were com­pared to the cri­ter­ion ­test of hydro­stat­ic weigh­ing (HW), (M=12.49%, SD=4.67%).
Results. Repeated meas­ures anal­y­sis of var­i­ance ­revealed the equa­tions of Lohman (M=12.94%, SD=3.59%, R=0.743, SEE=3.13%, TE=3.58%), Katch and McArdle (M=12.41%, SD=3.41%, R=0.750, SEE=3.10%, TE=3.18%), and Tipton and Oppliger (M=11.89%, SD=3.01%, R=0.763, SEE=3.03%, TE=3.63%) to be val­id. The equa­tions of Thorland et al. (M=14.11%, SD=5.12%, R=0.711, SEE=3.27%, TE=4.89%), Durning and Wommersley (M=14.075, SD=4.45%, R=0.741, SEE=3.13%, TE=4.71%), Jackson and Pollock (M=9.76%, SD=3.13%, R=0.737, SEE=3.17%, TE=5.90%), and Sinning (M=10.84%, SD=4.19%, R=0.741, SEE=3.13%, TE=4.78%) ­were sig­nif­i­cant­ly dif­fer­ent ­from HW.
Conclusions. It is con­clud­ed ­that the ­above-val­i­dat­ed for­mu­las ­have accept­ably low SEE’s and TE’s to be of prac­ti­cal val­ue in deter­mi­na­tion of appro­pri­ate ­weight class­es for col­le­giate wres­tlers.
