The aims of this study were to assess the criterion validity and the accuracy in estimating maximal aerobic power (VO2max) of a popular shuttle running field test (multistage fitness test [MSFT]) in women soccer players. Twenty-six women soccer players (age 12.1+/-0.9 years, body mass 50+/-9.2 kg, and height 155+/-5.7 cm) were tested over separate occasions for VO2max (VO2max test) and MSFT performances with (MSFT peak oxygen uptake) or without (MSFT) gas analysis. Data showed that the VO2max estimation using the MSFT predicting nomogram was significantly lower than MSFT VO2peak (32.7+/-3.9 vs. 40.1+/-5.9 ml.kg(-1).min(-1); p<0.001). No significant difference between VO2max test and MSFT for maximal VO2 and heart rate (HR) was observed (38.7+/-4.7 vs. 40.1+/-5.9 ml.kg(-1).min(-1) and 203+/-5.3 vs. 200+/-9.8 beats.min(-1); p>0.05; n=15). The MSFT performance (950+/-213 m) results significantly correlated with MSFT-VO2peak (r=0.70; p<0.001). This study results showed that the MSFT predicting nomogram significantly underestimated VO2peak. Average difference being in the order of 23% of the estimated value. Resulting MSFT-VO2peak significantly related to MSFT performance, and this test may be considered as an indirect measure of individual VO2max in young women soccer players. Furthermore, MSFT may be used as a valid test to assess VO2peak and HRmax when a portable gas analyzer and a HR monitor are available. However, great individual differences may occur. In light of this study results, it is suggested to consider MSFT performance (distance covered) and not estimated VO2max when dealing with young women soccer players.
本研究旨在评估一项流行的穿梭跑场测试（多级体能测试[MSFT]）在女性足球运动员中评估最大有氧能力（VO2max）的标准效度和准确性。26 名女性足球运动员（年龄 12.1+/-0.9 岁，体重 50+/-9.2 公斤，身高 155+/-5.7 厘米）分别在不同场合进行 VO2max（VO2max 测试）和 MSFT 表现测试（有（MSFT 峰值摄氧量）或没有（MSFT）气体分析。数据显示，使用 MSFT 预测图表估算的 VO2max 明显低于 MSFT VO2peak（32.7+/-3.9 对 40.1+/-5.9 ml.kg(-1).min(-1)；p<0.001）。VO2max 测试和 MSFT 之间在最大 VO2 和心率（HR）方面没有显著差异（38.7+/-4.7 对 40.1+/-5.9 ml.kg(-1).min(-1)和 203+/-5.3 对 200+/-9.8 beats.min(-1)；p>0.05；n=15）。MSFT 表现（950+/-213 米）结果与 MSFT-VO2peak 显著相关（r=0.70；p<0.001）。本研究结果表明，MSFT 预测图表显著低估了 VO2peak。估计值的平均差异在 23%左右。由此产生的 MSFT-VO2peak 与 MSFT 表现显著相关，该测试可被视为年轻女性足球运动员个体 VO2max 的间接测量。此外，当有便携式气体分析仪和心率监测器时，MSFT 可用于评估 VO2peak 和 HRmax 的有效测试。然而，个体差异可能很大。根据本研究结果，建议在处理年轻女性足球运动员时考虑 MSFT 表现（覆盖距离）而不是估计的 VO2max。
