comparison the effect of trx and traditional resistance training on responses some indices of muscle damage of soccer player

The purpose of this study was to compare the effect of two methods of resistance training trx and traditional resistance on the response of some indicators of muscle damage in soccer players. the present study was a semi-experimental; therefore, 36 participants with mean age of 19/36±1/4 were voluntarily selected and assigned to two groups of trx and traditional resistance training. the training program for both groups consisted of several joint movements, these movements in 2 sets, with 8 repetitions in to isometric form, and the duration of muscle tension in each movement was 20 seconds. both groups were evaluated by biochemical, physical and anthropometric measurements in two stages of pre-test and post-test. data analysis was done using independent sample t-test and paired sample t-test with the significant level of 0.05 (p≤0.05). serum creatine kinase levels showed a significant increase in traditional resistance training group 54.01% (p=0.001) and in the trx training group 58.19% (p=0.003). serum lactate dehydrogenase levels increased significantly as the result of traditional resistance training (p=0.033) while aspartate aminotransferase did not show any significant changes from pre-test to post-test in the experimental groups. moreover, the results of the present study showed that there was no significant difference in the changes observed in the indices of muscle damage between a traditional training and trx training. therefore, performing trx or traditional training is not improving muscle injury during training.
