This study examined the appropriate magnitude of allometric scaling of the Wingate anaerobic test (WAnT) power data for body mass (BM) and established normative data for the WAnT for adult men. Eighty-three men completed a standard WAnT using 0.1 kg·kg(-1) BM resistance. Allometric exponents and percentile ranks for 1-second peak power (PP), 5-second PP, and mean power (MP) were established. The Predicted Residual Sum of Squares (PRESS) procedure was used to assess external validity while avoiding data splitting. The mean 1-second PP, 5-second PP, and MP were 1,049.1 ± 168.8 W, 1,013.4 ± 158.6 W, and 777.9 ± 105.0 W, respectively. Allometric exponents for 1-second PP, 5-second PP, and MP scaled for BM were b = 0.89, 0.88, and 0.86, respectively. Correlations between allometrically scaled 1-second PP, 5-second PP, and MP, and BM were r = -0.03, -0.03, and -0.02, respectively, suggesting that the allometric exponents derived were effective in partialling out the effect of BM on WAnT values. The PRESS procedure values resulted in small decreases in R² (0.03, 0.04, and 0.02 for 1-second PP, 5-second PP, and MP, respectively) suggesting acceptable levels of external validity when applied to independent samples. The allometric exponents and normative values provide a useful tool for comparing WAnT scores in college-aged females without the confounding effect of BM. It is suggested that exponents of b = 0.89 (1-second PP), b = 0.88 (5-second PP), and b = 0.86 (MP) be used for allometrically scaling WAnT power values in healthy adult men and that the confidence limits for these allometric exponents be considered as 0.66-1.0 for PP and 0.69-1.0 for MP. The use of these exponents in allometric scaling of male WAnT power values provide coaches and practitioners with valid means for comparing power production between individuals without the confounding influence of BM.
本研究旨在探讨使用体质量（BM）对无氧能力测试（WAnT）功率数据进行合理的生物力学比例缩放的方法，并为成年男性制定 WAnT 的正常参考值。83 名男性使用 0.1kg·kg(-1) BM 阻力完成了标准的 WAnT。确定了 1 秒峰值功率（PP）、5 秒 PP 和平均功率（MP）的比例指数和百分位数等级。采用预测残差平方和（PRESS）程序来评估外部有效性，同时避免数据分割。1 秒 PP、5 秒 PP 和 MP 的平均值分别为 1049.1 ± 168.8W、1013.4 ± 158.6W 和 777.9 ± 105.0W。1 秒 PP、5 秒 PP 和 MP 按 BM 比例缩放的比例指数分别为 b = 0.89、0.88 和 0.86。1 秒 PP、5 秒 PP 和 MP 的比例缩放与 BM 的相关性分别为 r = -0.03、-0.03 和 -0.02，这表明得出的比例指数有效地排除了 BM 对 WAnT 值的影响。PRESS 程序的值导致 R²（1 秒 PP、5 秒 PP 和 MP 分别为 0.03、0.04 和 0.02）略有下降，这表明在应用于独立样本时，外部有效性处于可接受水平。比例指数和正常参考值为比较大学年龄段女性的 WAnT 分数提供了有用的工具，而不会受到 BM 的混杂影响。建议在健康成年男性中使用 b = 0.89（1 秒 PP）、b = 0.88（5 秒 PP）和 b = 0.86（MP）的比例指数对 WAnT 功率值进行比例缩放，并将这些比例指数的置信区间视为 0.66-1.0 用于 PP 和 0.69-1.0 用于 MP。在对男性 WAnT 功率值进行比例缩放时使用这些指数，可以为教练和从业者提供一种有效的方法，用于比较个体之间的力量产生情况，而不会受到 BM 的混杂影响。
