The interactive effect of aerobic training and resveratrol supplementation on C-reactive protein and metabolic profiles in women with type 2 diabetes

An increase in the level of inflammatory markers such as C-reactive protein (CRP) and metabolic profile are associated with increased cardiovascular diseases and are common in patients with type 2 diabetes. This study aimed to examine the interactive effect of aerobic training and resveratrol supplementation on CRP and metabolic profiles in women with type 2 diabetes. Twenty-seven women with type 2 diabetes­ (mean age of 27.9 years old, the fat percentage of 35.7% and BMI 28.3 kg.m2) were randomly assigned to three groups: aerobic training, aerobic exercise with supplements, and control. The first and second experimental groups performed aerobic exercise for 8 weeks, 3 sessions per week, with 60%-75% of maximum heart rate in each session for 40-50 minutes. The second group in addition to aerobic exercise received 400 mL of resveratrol supplement daily for 60 days. Changes in the indices, ­including CRP, LDL-C, HDL-C, fasting blood glucose, atherogenic index, total cholesterol, triglycerides and risk of coronary heart disease (CHD) were measured before and 48 hours after the last session. No significant reduction was found in the mean CRP level in the second group (P=0.123). Also, combination of resveratrol supplement and aerobic training significantly reduced fasting blood glucose­ (P=0.008), LDL-C (P=0.002), and atherogenic index­ (P=0.001), and significantly increased HDL-C­ (P=0.03), while it had no significant effect on total cholesterol ­(P=0.25), triglycerides ­(P=0.88) and risk of CHD ­(P= 0.14). Aerobic exercise along with resveratrol supplement seems to be a useful method for prevention and control of cardiovascular diseases and improving health in women with type 2 diabetes.
