Introduction: Type 2 diabetes has many complications, including cardiovascular disease, which is associated with an increase in inflammatory biomarkers. Research has shown that physical activity can reduce inflammatory factors and improve cardiovascular disease. The purpose of this study was to investigate the effect of resistance exercise on some of the inflammatory and anti-inflammatory factors in the heart tissue of type 2 diabetic rats. Methods: In this study, 18 male rats were selected. Rats were diabetic with nicotinamide and streptozotocin (stz) and then randomly divided into 2 groups of control (n=9) and training (n=9). The training group performed a resistance training program for 8 weeks, 5 days a week. Measurement of TNF-α and IL10 expression in the heart tissue was determined using the one step SYBR TAKARA single-step kit. To compare the difference between the mean of variables between exercise and control groups, independent t-test and t-test were used also to determine the effect of diabetes induction on variables. To determine the relationship between variables, Pearson correlation coefficient and separation correlation coefficient were used. Data were analyzed by SPSS software version 22. Results: The results showed that the insulin resistance index decreased significantly in the training group compared to the control group. On the other hand, the expression of TNF-α gene decreased and IL10 showed a significant increase (α≤0.05). Conclusion: The results indicate that resistance training may be effective in modulating the inflammatory factors of TNF-α and IL10 in the heart tissue of type 2 diabetic rats.
