The aims of this study were to assess the criterion validity and the accuracy in estimating maximal aerobic power ([latin capital V with dot above]o2max) 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 [latin capital V with dot above]o2max ([latin capital V with dot above]o2max test) and MSFT performances with (MSFT peak oxygen uptake) or without (MSFT) gas analysis. Data showed that the [latin capital V with dot above]o2max estimation using the MSFT predicting nomogram was significantly lower than MSFT [latin capital V with dot above]o2peak (32.7 ± 3.9 vs. 40.1 ± 5.9 ml·kg-1·min-1; p < 0.001). No significant difference between [latin capital V with dot above]o2max test and MSFT for maximal [latin capital V with dot above]o2 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-[latin capital V with dot above]o2peak (r = 0.70; p < 0.001). This study results showed that the MSFT predicting nomogram significantly underestimated [latin capital V with dot above]o2peak. Average difference being in the order of 23% of the estimated value. Resulting MSFT-[latin capital V with dot above]o2peak significantly related to MSFT performance, and this test may be considered as an indirect measure of individual [latin capital V with dot above]o2max in young women soccer players. Furthermore, MSFT may be used as a valid test to assess [latin capital V with dot above]o2peak 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 [latin capital V with dot above]o2max when dealing with young women soccer players.
