Abstract
Background and Aim: Football is known as the most popular sport in the world, and due to the nature of this sport and its injuries, researchers still do not know the effect of sports training on different levels. The aim of the current research is to compare the effect of a plyometric training course on indoor and grass environments on new biomarkers of muscle damage in soccer players Materials and Methods: In this semi-experimental and applied study, 36 youth soccer players were selected and divided into three groups (1) plyometric training on grass environments (number = 12 people), (2) Plyometric training on indoor environments (number=12 people) and (3) control (number=12 people) were divided. Plyometric trainings were performed on indoor and grass environments for eight weeks, two sessions per week and each session lasted 60 minutes. In order to analyze the findings, independent sample t- test, one-way analysis of variance with Tukey's post hoc tests were used (p≤0.05). Results: There is no significant difference in sTnT values in research groups; However, mtDNA values in the training on grass environments (p=0.001) and training on indoor environments (p=0.001) groups were significantly higher than the control group. Also, these values were significantly higher in the training on grass environments than in the training on indoor environments (p=0.001). Conclusion: Although training in both grass and indoor environments leads to an increase in mtDNA serum levels, nevertheless, the effects of training in grass environments are greater than in indoor environments.
