Background and Aim: Anabolic steroids cause damage to various tissues, including the heart. This study aimed to evaluate the effect of aerobic exercise on Malondialdehyde (MDA) and superoxide dismutase (SOD) of heart tissues in rats poisoned with the anabolic steroid Dianabol. Materials and Methods: In this experimental-fundamental study, ۱۸ rats were selected and divided into three ۶-series groups, including normal saline intake (Sh), Dianabol (D), and steroid intake with aerobic exercises (D+RT). For six weeks, the steroid and aerobic exercise groups received ۵ mg/kg of Dianabol per day peritoneally, and the steroid aerobic exercise group performed aerobic exercise five sessions per week. Measurement of MDA and SOD gene expression in heart tissue was measured by ELISA. Kolmogorov-Smirnov statistical tests, a ۱-way analysis of variance with Tukey post hoc test were used to analyze the results (P≤۰.۰۵). Results: Steroid Dianabol had a significant effect on increasing MDA (P=۰.۰۰۱) and decreasing SOD (P=۰.۰۰۱) in heart tissue. However, aerobic exercise decreased MDA (P=۰.۰۰۱) and increased the SOD antioxidant index (P=۰.۰۰۰) in the heart tissue of rats exposed to Dianabol. Conclusion: Anabolic steroids appear to increase oxidative stress indices and decrease antioxidants in heart tissue, while aerobic exercise can improve elevated levels of oxidative stress and decreased levels of antioxidants.
