The aim of the present study was to investigate the effects of different ambient temperatures on cellular damage after simulated wrestling training in adolescent wrestlers. From adolescent wrestlers of Kurdistan province who were champions in 2015provincial competitions, 21 wrestlers (age: 15.04±0.8 years, weight: 59.20±12.67 kg, height: 163.47±7.39 cm, body fat percent: 10.03±3.39%) were selected as subjects based on inclusion criteria. Then, according to personal characteristics, subjects were divided into three groups: high temperature, normal temperature and low temperature. After providing the desired ambient temperature (30, 18 and 10°C), subjects completed a training protocol based on wrestling techniques (8 stations in a circle). Blood samples were collected before, immediately and 30 minutes after the training. ANOVA with repeated measures and one-way ANOVA were used to investigate the differences within and among groups respectivelyat a significance level of 0.05. The results indicated that the levels of aspartate transaminase (AST) and alanine transaminase (ALT) increased in the three groups, but this increase was not statistically significant (P>0.05). Also, the levels of AST and ALT in high temperature group increased more than other groups.The results showed that heat stress could aggravate cellular damage in adolescent wrestlers. Thus, due to the importance of the adolescence period, it is recommended to pay special attention to the ambient temperature of training and competition gyms of this agegroup.
