Although skinfold-derived equations seem to be practical for field application in estimating body fat percentage (BF%) and minimum body mass in Olympic wrestlers, prediction equations applied first need to be cross-validated in Olympic wrestlers to define the best prediction equation. This study aimed to evaluate the most accurate field method to predict BF% in Olympic wrestlers compared to BF% estimated by air displacement plethysmography (ADP). Sixty-one male (body mass 72.4 ± 13.5 kg; height 170.3 ± 7.0 cm; body mass index (BMI) 24.9 ± 3.5 kg.m; BF% 8.5 ± 4.9%) and twenty-five female wrestlers (body mass 60.3 ± 9.9 kg; height 161.3 ± 7.1 cm; BMI 23.1 ± 2.5 kg.m; BF% 18.7 ± 4.7%) undertook body composition assessments including ADP and nine-site skinfold measurements. Correlations, bias, limits of agreement, and standardized differences between alterations in BF% measured by ADP and other prediction equations were evaluated to validate measures, and multiple regression analyses to develop an Olympic wrestlers-specific prediction formula. The Stewart and Hannan equation for male wrestlers and the Durnin and Womersley equation for female wrestlers provided the most accurate BF% compared to the measured BF% by ADP, with the lowest bias and presented no significant differences between the measured and predicted BF%. A new prediction equation was developed using only abdominal skinfold and sex as variables, predicting 83.2% of the variance. The findings suggest the use of the new wrestler-specific prediction equation proposed in the study as a valid and accurate alternative to ADP to quantify BF% among Olympic wrestlers.
虽然基于皮褶厚度的公式在估算奥运摔跤运动员的体脂百分比（BF%）和最低体重方面似乎适用于现场应用，但首先应用的预测公式需要在奥运摔跤运动员中进行交叉验证，以确定最佳预测公式。本研究旨在评估与通过空气置换体积描记法（ADP）估算的BF%相比，预测奥运摔跤运动员BF%的最准确现场方法。61名男性（体重72.4±13.5千克；身高170.3±7.0厘米；体重指数（BMI）24.9±3.5千克·米²；BF% 8.5±4.9%）和25名女性摔跤运动员（体重60.3±9.9千克；身高161.3±7.1厘米；BMI 23.1±2.5千克·米²；BF% 18.7±4.7%）进行了身体成分评估，包括ADP和九部位皮褶测量。评估了ADP测量的BF%变化与其他预测公式之间的相关性、偏差、一致性界限和标准化差异，以验证测量方法，并进行多元回归分析以开发特定于奥运摔跤运动员的预测公式。与ADP测量的BF%相比，男性摔跤运动员的Stewart和Hannan公式以及女性摔跤运动员的Durnin和Womersley公式提供了最准确的BF%，偏差最低，且测量的BF%与预测的BF%之间无显著差异。仅使用腹部皮褶和性别作为变量开发了一个新的预测公式，可预测83.2%的方差。研究结果表明，本研究中提出的新的特定于摔跤运动员的预测公式可作为ADP的有效且准确的替代方法，用于量化奥运摔跤运动员的BF%。
