| Background and Aim: It seems that vitamin-mineral supplementation reduce exercise-induced oxidative stress. However, the adaptation occurred after vitamin-mineral supplementation, especially in pubertal, age is not clear yet. Therefore this study is aimed to investigate the effects of vitamin-mineral supplementation on anti-oxidant enzymes, Malone Dialdehyde (MDA), and performance in young elite swimmers in pubertal age. Materials and Methods: Twenty-four female elite swimmers (12.93 1.22) volunteered to participate in this study and were randomly divide into two groups: vitamin-mineral supplemented (N=12) and control (N=12) groups. Both groups participated in a monthly swimming program (they trained three times a week for a total of four weeks). They swam almost 3.5 to 4 km/day Blood sampling was done before and after training period to assess anti oxidant enzymes. 100 m crawl records were measured at the beginning and at the end of training period. Independent t test and paired sample t test were used to analyze the data. Results: Antioxidant enzymes increased in vitamin-mineral supplemented group but this increase was only significant in superoxide dismutase (p<0.04). In control groups, glutathione peroxidase (GSH-Px) significantly decreased (p<0.01). In between-groups comparison, superoxide dismutase (p<0.04) and GSH-Px (p<0.002) had a significant change at the end of the period. No significant change was observed in MDA and swimming performance in both groups. Conclusion: Vitamin/mineral supplementation especially during heavy swimming training was found to improve some antioxidant enzymes performance during pubertal age that can be considered by coaches in high level. |
