Background & aim:  Type 2 diabetes exerts oxidative and anti-angiogenic effects through different pathways in the heart tissue. The aim of the present study was to determine and evaluate the effect of 4 weeks aerobic training on oxidative stress and angiogenesis in cardiac tissue of male rats with type 2 diabetes.
 
Methods: In the present experimental study, 30 male Wistar rats were randomly divided into three equal diabetic groups with aerobic training, diabetic control group and healthy control group. Induction of type 2 diabetes was induced by intraperitoneal injection of STZ. The incremental aerobic exercise protocol consisted of 4 weeks, 5 sessions per week of running on the treadmill at a speed of 20 m/min for 60 min. ROS and NO levels were measured by spectrophotometer and colorimetric respectively. Expression of HIF-1α and VEGF genes were evaluated by Real time PCR. Data were analyzed using one-way ANOVA and Bonferroni post hoc tests.
 
Results: the results revealed that type 2 diabetes significantly increased ROS (p<0.05) and decreased NO (p<0.05), HIF-1α (p<0.05) and VEGF (p>0.05) compared with control group. Aerobic training significantly decreased ROS (p<0.05) and NO (p<0.05) and increased HIF-1α (p<0.05) and VEGF (p<0.05) genes respectively in comparison with the control group. Also, aerobic training significantly reduced glucose (p<0.05) compared to the control group.
 
Conclusion: Type 2 diabetes increased oxidative stress in heart tissue and disrupted the process of angiogenesis in diabetic heart. Aerobic exercise seemed to have a positive effect on the process of angiogenesis by decreasing ROS and can improve diabetic heart.
