Objective: High intensity interval training (HIIT) and continues aerobic training have cardio-protective effects in diabetic rats. The aim of this study was to compare the effect of HIIT and continues aerobic training (CAT) on MIR29A and collagen I gene expression in heart of diabetic male rats.
Materials and Methods: In this randomized controlled clinical trial, 18 male diabetic rats were studied. They were divided into 3 groups as HIIT, CAT and control group. Exercise protocol was performed 5 days/week for 5 weeks. The MIR29A and collagen I synthesis were compared between the groups.
Results: Findings showed MIR29A expression is statistically higher in HIIT and CAT group than control group (P-value<0.001) and (P-value:0.053). Also MIR29A expression is significantly higher in HIIT group compared to CAT group (P-value:0.034). Collagen I expression was significantly lower in HIIT and CAT group compared to control group (P-value<0.001) and (P-value:0.001). Collagen I expression was lower in HIIT group compared to CAT group (P-value:0.027).
Discussion: The results of this study demonstrated that, HIIT increases MIR29A expression which is along with reduction in collagen I synthesis in cardiac muscles increases the risk of myocardial fibrosis in diabetic rats.
