Effect of various ambient temperatures on proinflammatory cytokines levels and oxidative stress index of adolescencewrestlers

In addition to physical, physiological, psychological and technical factors, the environmental parameters such as ambient temperature could also have an affect on the performance of athletes and especially their health. Therefore, the purpose of present study was to investigate the effects of different ambient temperature on the level of proinflammatory and oxidative stress markers in adolescence wrestlers.
21 adolescence wrestlers of Kurdistan province clubs participated as subjects in this study. Based on body composition and anthropometric profiles, subjects were divided into three groups. After providing the desired temperature (30 °C, 18 °C and 10 °C), subjects were asked to complete a Wrestling Technique Based on Circuit Training protocol. Blood samples were collected before, immediately and 30 minutes after exercise. The Repeated measures analysis of variance and Tukey post hoc tests were used to analyze the results, and the significant level was set at p
The results showed that the levels of interleukin-6 (p=0.01) and tumor necrosis factor alpha (p=0.01) significantly increased after exercise in high temperatures group, but no significant changes were observed in the other groups. Also, the increase rate of IL-6 was higher in high temperature group and there was also significant differences between normal temperature - high temperature groups (p=0.001) and low temperature - high temperature groups (p=0.001). In addition, intra-group changes malondialdehyde in all groups were not statistically significant (p=0.56). Also, there were no significant differences between group (p=0.25).
The results showed that heat stress may increase inflammation and oxidative stress in the adolescence wrestlers. Thus, due to the sensitivity of adolescence period it is suggested that pay special attention to ambient temperature of competition and enviroements of this age- group.
