Background & Objective: Nowadays, due to the epidemic of sports supplements, the effects of these supplements on total antioxidant capacity require analysis and evaluation. Therefore, the purpose of the present study is the effect of L-Arginine supplementation on indices of delayed-onset muscle soreness after one-session exhaustive aerobic training in inactive men.
Materials & Methods: The population of this quasi-experimental are 20 male that were selected on a voluntary basis. The samples were randomly divided into two groups of L-arginine (n = 10) and placebo (n = 10). The subjects participated in three phases of aerobic activity. Blood samples were collected during the first phase before and after aerobic test, but in the second and third phases after receiving three days supplementation and placebo immediately after aerobic running. For extraction of results the ANOVA with repeated measures and paired t-test were applied and the significant level set as P<0.05.
Results: The results indicate that after the pre and post Stage one (before receiving of supplementation and placebo), a significant difference was found in serum creative kinase (CK), lactate dehydrogenase (LDH) and neutrophil counts in both groups. The results between groups indicated that there was a significant difference between two groups in the return of the primary state in blood lactate and heart rate. Also the results shows that CK, LDH and neutrophil counts in L-Arginine supplementation group was significantly lower than Placebo group after the resistance exercise session.
Conclusion: The findings of this study indicate that l-Arginine supplementation can cause a significant decrease in indices of delayed-onset muscle soreness (DOMS).
