Background: Diabetes and its oxidative stress increase the effects of this disease on heart tissue. On the other hand, exercise improves the antioxidant status of heart tissue. The aim of this study was to investigate the effect of 8 weeks of increased endurance training on superoxide dismutase activity and malondialdehyde levels in the heart tissue of mice with type 2 diabetes.
Methods: In this experimental study, 24 male Wistar rats (256 ±11.8 g, 10 weeks old) were divided into 4 groups of 6. Exercise program for 8 weeks of increasing endurance training. 48 h after completion of the protocol, the activity of superoxide dismutase enzyme and malondialdehyde levels in rat heart tissue were measured. One-way analysis of variance was used for group comparisons and Pearson test was used to examine the relationship between indicators.
Results: There were significant difference between the four groups in superoxide dismutase (P= 0.001) and malondialdehyde (P= 0.001) indices. As a result of post-hoc test, there were significant increase in superoxide dismutase index in healthy exercise (P= 0.016) and control groups (P= 0.029) compared to diabetic control group and significant decrease in malondialdehyde index in control (P= 0.003), diabetic exercise (P= 0.050) and healthy exercise groups (P= 0.001) compared to diabetic control group. Significant correlation was observed between superoxide dismutase and malondialdehyde indices (r= 0.018, P= 0.274).
Conclusion: According to the results of this study, it seems that incremental endurance training reduces lipid peroxidation and improves antioxidant status and consequently reduces oxidative stress in cardiac tissue of diabetic rats.
