The 30s Wingate Anaerobic Test (WAnT) is a common evaluation method used by elite athletes to evaluate the training effect of anaerobic exercise capacity. However, the commonly used 7.5% body weight is used as the WAnT load in wrestling, judo and other confrontation events. It often fails to faithfully reflect the improvement of training ability, which leads to the phenomenon of "false negative" in the judgment of training effect. PURPOSE: To explore the optimal load of WAnT test for evaluating the anaerobic exercise capacity of outstanding male freestyle wrestlers. METHODS: 10 active national male freestyle wrestlers (22.8±1.9 yrs) were tested before and after training with 10%, 7.5%, and 5% of the body mass (BM) representing three kinds of load: large, medium, and small. Peak Power (PP), Mean Power (MP), and Fatigue Index (FI) are used as indicators to evaluate the anaerobic capacity of outstanding male freestyle wrestlers. Two-factor repeated measures analysis of variance was used to compare the differences before and after training and between different loads. RESULTS: Under a large load of 10% BM, PP (9.85+1.59 vs. 10.99+1.38, p <0.05) and MP (7.27+1.27 vs. 8.36+0.94, p <0.05) after training increased significantly compared with before training, and there was no significant change under medium and small loads of BM7.5% and BM5%. After training, PP and MP (8.36+0.94 vs. 7.83+0.43 vs. 6.25+0.24, p <0.05) under the heavy load of BM10% were significantly different from the medium and small loads of BM7.5%, BM5% and BM5%. There was no significant change in FI before and after training and between different loads. CONCLUSIONS: The weight load selection of WAnT is an important factor that affects its test accuracy; for national male freestyle wrestlers with excellent strength levels, heavy load is a better load to evaluate their anaerobic capacity and training effect.
