Effects of aerobic exercise on lipids profile and insulin resistance in patients with type 2 diabetes

Aim: Lipid abnormalities significantly contribute to the increased risk of cardiovascular disease and other morbidity in diabetics. The aim of present study was to examine the effect of 8 weeks aerobic training on lipid profile and insulin resistance in patients with type 2 diabetes. Material & Methods: Twenty four middle-aged men (age, 40 -50 years, 44.0 ± 2.3 mean ± SD) with type 2 diabetes participated as the subject. The subjects were randomly assign to control group (n=12) or the training group (n=12). The subjects in the training group performed 35 to 50 min aerobic training on bicycle ergometer with 40-55% of their heart rate reserve (HRR), 3 days a week for 8 weeks. The subjects in the control group were instructed to maintain their normal physical activity throughout the study. Results: The results indicated blood lipid profile improved in the training group. The results also revealed that fasting blood sugar, fasting insulin and insulin resistance index decrease in the training group compare to the control group (P<0.05). Conclusion: In summary, it seems that aerobic training utilized in this study improves blood lipid profile and insulin resistance in patients with type 2 diabetes
