The ultimate goal of exercising is to improve performance. For this purpose, the athlete needs to increase the volume and intensity of the exercise, which is a factor that challenges the homeostasis of the body. The purpose of this study was to investigate the effect of dietary intake of carbohydrate and protein carbohydrate on testosterone and salivary cortisol following two quasi-competitive races in amateur male wrestlers. For this purpose, 16 wrestlers (amateurs) were selected based on physical characteristics such as: height 169.62 ± 10.99 cm, weight 63.09 ± 23.1kg, 17.7 ± 3.70 years, fat percentage 14.97 ± 5.89, Physical fitness, history of wrestling and body mass index were selected and the subjects were divided into two groups: the first group received carbohydrate and the second group received protein carbohydrate after a single blind crossover activity. Carbohydrate sport drink was (10% solution) was 6 ml / kg and protein carbohydrate sport drink was (10% solution) 8% carbohydrate and 2% protein. The subject's nutrition was identical on the day of the test and two separate control and experimental sessions were performed within one week. On the test day, the subjects held two wrestling matches with 10 minutes of rest between the matches. The unstimulated saliva sample in the first and second weeks of two stages and once before the match, after 30 minutes and 3rd time three hours after the competition and in total during six rounds were measured in two matches. The testosterone and salivary cortisol levels were measured by ELISA and the results were analyzed by SPSS software, Shaproilk Statistical test and repetitive statiscal analysis (ANOVA) was performed at a significant level of 0.05. In general, the results of this study showed that the response of testosterone, cortisol, and testosterone to cortisol ratio was similar between males and at 30 minutes and 180 minutes after two semi-competitive wrestles, and the type of supplementation did not affect the response pattern of these variables (P<0.05). In addition, the levels of each of these indices did not differ between the two groups before the implementation of the competitive activity (P <0.05).
