Abstract
Objective: High-intensity interval training (HIIT) and continues aerobic training (CT) have cardio-protective effects in diabetic rats. The functional role of microRNA in heart was studied. Only miR-29a levels were found to correlate with cardiac fibrosis, This study tests the hypothesis that applying HIIT and CT cases miR-29a increasing is associated with a reduction of connective tissue growth factor (CTGF) induced cardiac fibrosis.
Materials and Methods: In this randomized controlled trial, 18 male diabetic rats were included. They were divided into 3 groups called as HIIT, CT and control. Exercise protocol was performed 5 days/week for 5 weeks. The miR-29a and CTGF synthesis were compared between the groups by real time- PCR.
Results: Our results demonstrated that elevation of miR-29a using HIIT (2.67 , P=0.010,) or CT (1.79 , P=0.002) are effective in inhibiting CTGF (HIIT:0.17 P=0.000-CT:0.39 -induced cardiac fibrosis, suggesting that these types training would be selected as a new adjunctive therapy in the heart fibrosis- derived diabetic.
Discussion: The HIIT and CT showed increased levels of miR-29a compared CT group which is shown to decrease CTGF level resulting into lowered fibrosis of heart tissue in diabetic patients.

Abstract
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.

Abstract
Recent research is about the role of miR-29 accompanied by various conditions especially during the physical activity is a case of special attention, such as high intensity interval training (HIIT) and continuous aerobic training (CT) protective in heart, renal, lung, liver and even immune system adaptation. Since recent studies indicated the rolls of miR family on health and disease such as the effect of miR on health parameters evaluation and cardiovascular-respiratory, diabetic cardiomyopathy, diabetes, hypertension, myocardial infarction, gastric and breast cancer. Blocking harmful genes such as COL-1, CTGF, SMAD3, TGF-β, NFK-B and genes expression related to health such as miR-29 is a primary approach in treatment of some diseases. Meanwhile sports as HIIT and CT can be safe approach for genes expression related health and blocking harmful genes. This regulations applies by miRs especially miR-29 that is one mystery regulator in variety of diseases. We will give a brief account of relation between sports activities and miR-29 expression in this review.
