The aim of this study was to analyze the validity of 4 regression equations to estimate the peak oxygen consumption (V[Combining Dot Above]O2peak) from the 20-m shuttle run test in adolescents aged 11-13 years. One hundred and fifteen adolescents, 61 boys (mean ± SD: age = 12.3 ± 0.9 years) and 54 girls (age = 12.1 ± 0.7 years) performed the 20-m shuttle run test and an incremental progressive maximal test for direct V[Combining Dot Above]O2peak analysis. Four linear regression equations were used to estimate the V[Combining Dot Above]O2peak: Barnett et al. (equation 1), Léger et al. (equation 2), Mahar et al. (equation 3), and Matsuzaka et al. (equation 4). For boys, only the V[Combining Dot Above]O2peak estimated by EQ3 did not differ from the value directly measured (p > 0.05). The EQ1, EQ2, and EQ4 underestimated the V[Combining Dot Above]O2peak, whereas the EQ3 overestimated, particularly in girls (p < 0.05). Large limits of agreement were found between the reference method and the 4 equations, with higher estimated values by EQ2 for boys (8.36 ± 15.24 mL·kg·min) and girls (2.45 ± 12.63 mL·kg·min). The highest correlation values were observed by EQ4 for boys (r = 0.80), EQ1 for girls (r = 0.72), and EQ3 for total sample (r = 0.80). The equations analyzed were not precise for individual V[Combining Dot Above]O2peak prediction; however, the EQ3 revealed better agreement, particularly for boys. Considering the data obtained in the boys and total sample, our results suggest that the EQ3 may provide the best predictive measure of V[Combining Dot Above]O2peak from the 20-m shuttle run test in adolescents aged 11-13 years.
这项研究的目的是分析 4 个回归方程在 11-13 岁青少年中从 20 米穿梭跑测试中估计最大摄氧量（V[Combining Dot Above]O2peak）的有效性。115 名青少年（61 名男孩，平均年龄 ± 标准差：年龄 = 12.3 ± 0.9 岁；54 名女孩，年龄 = 12.1 ± 0.7 岁）进行了 20 米穿梭跑测试和递增性最大测试，以直接分析 V[Combining Dot Above]O2peak。使用了 4 个线性回归方程来估计 V[Combining Dot Above]O2peak：Barnett 等人（方程 1）、Léger 等人（方程 2）、Mahar 等人（方程 3）和 Matsuzaka 等人（方程 4）。对于男孩，只有 EQ3 估计的 V[Combining Dot Above]O2peak与直接测量值无差异（p > 0.05）。EQ1、EQ2 和 EQ4 低估了 V[Combining Dot Above]O2peak，而 EQ3 高估了 V[Combining Dot Above]O2peak，特别是在女孩中（p < 0.05）。参考方法与 4 个方程之间存在较大的一致性界限，对于男孩，EQ2 估计值较高（8.36 ± 15.24 mL·kg·min），对于女孩，EQ2 估计值较高（2.45 ± 12.63 mL·kg·min）。对于男孩，EQ4 观察到最高的相关值（r = 0.80），对于女孩，EQ1 观察到最高的相关值（r = 0.72），对于总样本，EQ3 观察到最高的相关值（r = 0.80）。对于个体 V[Combining Dot Above]O2peak 预测，分析的方程不精确；然而，EQ3 显示出更好的一致性，特别是对于男孩。考虑到在男孩和总样本中获得的数据，我们的结果表明，在 11-13 岁青少年中，EQ3 可能提供了从 20 米穿梭跑测试中估计 V[Combining Dot Above]O2peak 的最佳预测指标。
