This study determined the most effective field method for quantifying body fat percentage in male elite youth soccer players and developed prediction equations based on anthropometric variables. Forty-four male elite-standard youth soccer players aged 16.3-18.0 years underwent body fat percentage assessments, including bioelectrical impedance analysis and the calculation of various skinfold-based prediction equations. Dual X-ray absorptiometry provided a criterion measure of body fat percentage. Correlation coefficients, bias, limits of agreement, and differences were used as validity measures, and regression analyses were used to develop soccer-specific prediction equations. The equations from Sarria et al. (1998) and Durnin & Rahaman (1967) reached very large correlations and the lowest biases, and they reached neither the practically worthwhile difference nor the substantial difference between methods. The new youth soccer-specific skinfold equation included a combination of triceps and supraspinale skinfolds. None of the practical methods compared in this study are adequate for estimating body fat percentage in male elite youth soccer players, except for the equations from Sarria et al. (1998) and Durnin & Rahaman (1967). The new youth soccer-specific equation calculated in this investigation is the only field method specifically developed and validated in elite male players, and it shows potentially good predictive power.
本研究确定了在男性精英青年足球运动员中量化体脂百分比的最有效现场方法，并基于人体测量变量开发了预测方程。44名年龄在16.3 - 18.0岁的男性精英水平青年足球运动员接受了体脂百分比评估，包括生物电阻抗分析以及各种基于皮褶厚度的预测方程计算。双能X线吸收法提供了体脂百分比的标准测量值。相关系数、偏差、一致性界限和差异被用作有效性指标，回归分析用于开发特定于足球运动员的预测方程。Sarria等人（1998年）和Durnin与Rahaman（1967年）的方程具有非常高的相关性和最低的偏差，但它们在方法之间既未达到实际有价值的差异，也未达到实质性差异。新的特定于青年足球运动员的皮褶厚度方程包括肱三头肌和肩胛下皮褶厚度的组合。除了Sarria等人（1998年）和Durnin与Rahaman（1967年）的方程外，本研究中比较的任何实用方法都不足以估计男性精英青年足球运动员的体脂百分比。本研究中计算出的新的特定于青年足球运动员的方程是唯一专门针对精英男性运动员开发和验证的现场方法，并且显示出潜在的良好预测能力。
