The Impact of the Wingate Test on Anaerobic Power in the Lower Limbs of Athletes with Varied Time and Load

This study investigates the effects of Wingate anaerobic test (WAnT) on anaerobic capacity(AC) at different time (20s, 30s, 40s, 45s) and resistance load (7.5%BM, 8.5%BM, 9.5%BM, 10.5%BM).12 male runners of 200m、400m were subjected to four wingate tests of different times and loads.The changes of AC and lower limb muscle characteristics were analyzed by WAnT and electromyography.The result shows that the IEMG, RMS%, MPF and AC of lower limb muscles of RF，BF，VM，VL，TA and LG were increased by time (P < 0.05 or P < 0.01), but there was no significant difference in IEMG of MG (P > 0.05). Load significantly increased AC, IEMG, RMS% and MPF of lower limb muscles (P < 0.01). The interaction effect of time and load had no significant difference on PP, MP, RPE, IEMG, RMS% and MPF (P > 0.05), but increased on FI (P < 0.05).In conclusion, for 200m and 400m athletes, it is recommended to use a combination of 20s and 10.5%BM load to achieve optimal peak power and training effect,as well as a combination of 20s and 9.5%BM load for better average power and training effect.
