Effect of a Single Session of Combined Training Along with Garlic Extract Supplementation on Oxidative Stress Biomarkers in Professional Girl Swimmers

Oxidative stress has pivotal role in many complications. The purpose of this study was to assess the effect of a single session of combined training along with garlic extract supplementation on oxidative stress markers in professional girl swimmers. In this study, we purposefully chose 40 girl swimmers of Zahedan city, then were divided them into four separate groups as control, combined training along with supplement, combined training along with placebo and supplement groups. Blood samples in the first day were collected. Then, the supplement and placebo groups received two garlic tablets (800 mg/day) and starch capsules, respectively. After two weeks, a single session of combined training was performed by training placebo supplement training groups. Then, blood samples were again collected immediately after exercise. Malondialdehyde and total antioxidant capacity levels were determined by the commercial assay Kits. Data were analyzed by one-way ANOVA using SPSS software. The results showed that two weeks garlic supplementation and a single combined training session didn’t make a significant difference in the levels of oxidative stress indices i.e. malondialdehyde and total antioxidant capacity between groups (P>0.05). But, it seems that the total antioxidant capacity in supplement group was significantly greater than other groups. Due to the antioxidant properties of garlic, the induction of oxidative stress during exercise and the disturbance of redox balance, the present results suggest that the two weeks consumption of garlic supplementation cannot reduce or prevent oxidative stress.
