Whether bioelectrical impedance and skinfold analysis can be used interchangeably to establish minimal wrestling weights (MWWs) is unknown. Using both methods in a particular program may result in the misclassification of some athletes.
To compare the MWW calculated from skinfold measurements with those derived from 5 bioelectrical impedance equations and determine if the 2 methods could be used interchangeably for high school wrestlers.
Repeated measurements were obtained using bioelectrical impedance and skinfold analysis to determine MWWs. Data were collected during the preseason.
High school.
Two hundred eight wrestlers (151 males, 57 females), aged 13 to 18 years.
MAIN OUTCOME MEASURE(S): The bioelectrical impedance analysis was conducted with the MWW protocol administered annually by certified athletic trainers. The resistance and reactance were used in 5 equations to investigate the level of agreement between bioelectrical impedance and skinfold analysis for determining MWW. The MWWs were based on a minimum body fat of 7.0% for males and 14.0% for females.
When comparing bioelectrical impedance and skinfold analysis, we found prediction error ranged from 1.51 to 2.34 kg for males and 0.27 to 9.16 kg for females.
To protect the health of the athletes and maintain competitive equity, a single method should be used to determine MWWs. Bioelectrical impedance and skinfold analysis cannot be used interchangeably to determine MWWs.
生物电阻抗分析和皮褶厚度分析是否可以互换使用以确定最小摔跤体重（MWW）尚不清楚。在特定项目中同时使用这两种方法可能会导致一些运动员被错误分类。
比较通过皮褶测量计算出的MWW与通过5种生物电阻抗方程得出的MWW，并确定这两种方法是否可以互换用于高中摔跤运动员。
使用生物电阻抗分析和皮褶厚度分析进行重复测量以确定MWW。在季前赛期间收集数据。
高中。
208名摔跤运动员（151名男性，57名女性），年龄在13至18岁之间。
生物电阻抗分析采用由认证运动训练师每年实施的MWW方案进行。电阻和电抗被用于5个方程，以研究生物电阻抗分析和皮褶厚度分析在确定MWW方面的一致性水平。MWW基于男性最低体脂7.0%和女性最低体脂14.0%。
比较生物电阻抗分析和皮褶厚度分析时，我们发现男性的预测误差范围为1.51至2.34千克，女性为0.27至9.16千克。
为保护运动员健康并维持竞争公平性，应使用单一方法来确定MWW。生物电阻抗分析和皮褶厚度分析不能互换使用来确定MWW。
