The purpose of this study was to compare estimations of minimal wrestling weight (MWW) from experienced high school wrestling coaches and anthropometric equations with those from underwater weighing. Eighty-two wrestlers (X age +/- SD = 16.54 +/- 1.05 yr) volunteered to be assessed via anthropometry and underwater weighing, with percent body fat calculated from body density (BD) using both the conversion constants of Lohman [percent body fat = [5.03/BD) - 4.59) x 100] and Brozek [percent body fat = [4.57/BD) - 4.142) x 100]. In addition, five head coaches, who had between 5 and 24 yr of experience, were asked to estimate within 1 lb the MWW for each of their athletes. The validity of four selected anthropometric equations and the coaches' estimates were compared with the actual MWW from underwater weighing by examining the constant error (CE), r, SEE, and total error (TE) values. The results indicated that the skinfold equation (EQ1) of Lohman provided the most accurate estimates of MWW (TE = 1.90-2.09 kg) and is therefore recommended over the subjective estimates of high school coaches.
本研究的目的是比较经验丰富的高中摔跤教练和人体测量方程对最小摔跤体重（MWW）的估计值与水下称重得出的结果。82名摔跤运动员（年龄X±标准差 = 16.54±1.05岁）自愿接受人体测量和水下称重评估，使用洛曼的转换常数[体脂百分比 = [5.03/身体密度（BD）- 4.59]×100]和布罗泽克的转换常数[体脂百分比 = [4.57/BD - 4.142]×100]根据身体密度计算体脂百分比。此外，还要求5名有5至24年经验的主教练对其每位运动员的最小摔跤体重在1磅范围内进行估计。通过检查恒定误差（CE）、r、标准误（SEE）和总误差（TE）值，将四个选定的人体测量方程和教练估计值的有效性与水下称重得出的实际最小摔跤体重进行比较。结果表明，洛曼的皮褶厚度方程（EQ1）对最小摔跤体重的估计最为准确（总误差 = 1.90 - 2.09千克），因此比高中教练的主观估计更值得推荐。
