Effects of Aerobic Exercise and Calorie Restriction (Low-Carb Diet and Standard Diet) on Adipokines Affecting Insulin Resistance in Rats Type 2 Diabetes

The aim of this study was to evaluate the interactive effects of calorie restriction (standard diet and low-carb diet) in combination with aerobic exercise on the adipokines that are affective on insulin resistance in type 2 diabetic male rats. In an experimental study, 48 male Wistar rats (age 10 weeks, weight 229±19.5g) were randomly divided equally into six groups after diabetes induction. Group1: Diabetic control, group 2: 20% negative balance calorie with aerobic exercise, group 3: 20% caloric restriction with standard diet, group4: 20% caloric restriction with low carbohydrate diet, group 5: 20% caloric restriction with standard diet aerobic exercise and group6: 20% calorie restriction with low-carb diet aerobic exercise. Then 20% of negative energy balance was carried out on a daily basis of all groups for 8 weeks. Results showed that exercise alone and in combination with low-carb diet caused a significant increase in the Omentin-1 compared to diabetic control group (P≤0.05). But no significant differences were observed in the chemerin between the experimental groups with diabetic control group. The results also showed that the standard diet group and the low-carbohydrate diet alone and in combination with exercise were significantly improved insulin resistance (P≤0.05). This study showed that combination of aerobic exercise and low carbohydrates diet can increase Omentin-1 and improve insulin sensitivity in rats with type 2 diabetes.
