Comparison of the effects circuit training on some indicators of the purine nucleotide cycle in wrestlers

Research shows that one component affecting systems and energy sources is the intensity of activity, which can influence the sources of adenosine triphosphate (ATP) regeneration. This research aimed to compare two different methods of wrestling training in terms of metabolic efficiency and effect on the indicators of the nucleotide purine cycle.

Considering body weight, 21 athletes were divided into two groups of circuit exercises based on wrestling techniques (n=10) and the group of prevalent wrestling exercises (n=11). After conducting physical and physiological tests, blood sampling was taken before and after eight weeks at rest to measure hypoxanthine, hypoxanthine-guanine-phosphoribosyl-transferase, lactate, uric acid, xanthine, and Keratin-kinase. For eight weeks, the athletes practiced six wrestling techniques in a circuit and prevalent wrestling exercises. Independent t-test, analysis of variance with repeated measures (ANOVA), analysis of covariance (MANCOVA), and post hoc LSD test was used for data analysis.

The results showed that here was no significant difference in the levels of hypoxanthine-guanine phosphoribosyl-transferase (P=0.31), hypoxanthine (P=0.66), xanthine (P=0.62), plasma uric acid. (P=0.1), lactate (P=0.3) and Keratin kinase (P=0.47) between the two groups. However, in the intra-group analysis, hypoxanthine values ​​decreased significantly after eight weeks of circuit exercises based on wrestling techniques (P = 0.0001) and prevalent wrestling exercises (P = 0.0001).

According to the results wrestling exercises effectively change the metabolism of purines. Furthermore, the comparison of the two methods of wrestling training demonstrated that there were no differences between them, and they affect the indicators of the nucleotide purine cycle to the same extent.
