Competition in the morning Confronts athletes with the problem of susceptibility to infection and inflammation. The purpose of this study was to examine The effect of two weeks morning and afternoon special training program on performance and plasma levels of IL-17 and cortisol in boy wushu athletes Materials and Methods: Fourteen sanda boy athletes were purposefully selected and after Bruce and rast tests run, divided into the two Similar groups morning-time training group (N = 7, training time 9 a.m.) and evening-time training group (N=7, training time 18 pm ). The Subjects were trained for two weeks (6 session in each week) according to an Sanda sport specific training program. Values of peak anaerobic power, average anaerobic power, minimum anaerobic power and fatigue index measured with Field rast test. To determine the amount of plasma IL-17 and cortisol , the participants’ blood samples was taken In the fasting state three times, 24 h before the first training session in baseline status and Immediately after tests at 9 am and 48 h after the last training session immediately after tests performance at 9 a.m. Data were analyzed using repeated measures, independent-samplesT-test, ,paired- samplesT-test and Covariance. Results: The results showed that there were significant differences between the amounts of plasma IL-17 of the two groups after two weeks(P<0.05). But there were not any significant differences between the amounts of plasma cortisol and performance of both groups after two weeks(P>0.05). Conclusion: It seems likely transition training time to the morning, 2 weeks before the competition in the morning, decrease inflammatory factors such as IL-17 in sanda boys. Therefore appears that two weeks transition training time from evening to morning can increase the safety of athletes immune during the competition.
