The purpose of this study was to survey the Effect of time of day on anaerobic responses with high intensity exercise. 12 athletes (22.53 ± 3.18 year, 174.32 ± 2.65 cm, 70.12 ± 2.18 kg) with background 3 years experience in physical activity suddenly selected. From Wingate test used for evaluation of participation’s maximal anaerobic power. Vo2max was recorded during the test (30 sec) in morning (8 o’clock) and after 3 days in evening (6 o’clock). The effect of time of day was tested using independent t tests for comparisons data. Statistical significance was set at p<0.05. Results of present study were shown that During the Wingate test increased anaerobic power. VO2max increased significantly from morning to evening during the Wingate Test. And that was significant statistically. Time of day effects on anaerobic performances during the Wingate test is mainly due to better aerobic participation in energy production during the test in the evening than in the morning.
