Background and Objective: The aim of this study was to investigate the impact of circuit resistance exercise training on metabolic parameters in type 2 diabetics men.Subjects and Methods: Twenty seven types 2 diabetic men of ahvaz city selected as subjects and were randomly assigned into two exercise (n=15, aged 46.40±3.02 yrs) and control (n=12, aged 45.06±3.86 yrs) groups. Exercise training was performed for eight weeks, 3 days a week with intensity corresponding to 30-70% 1 Repition Maximum. Before and after exercise anthropometeric and biochemical factors after a 12-h fasting were measured. Statistical analysis was carried out using T-test, at significance level of P£0.05.Result: Finding showed a significant reduction in fasting glucose, HbA1c, fructosamine, insulin, HOMA-IR and significant increase in HDL-c, in the exercise group compared to pre-exercise and control groups (P£0.05). While, there was no significant change in triglycerides, total cholesterol, LDL-c in the exercise group compared to pre-exercise and control groups (P£0.05).Conclusion: It seems circuit resistance training can improve glycemic profile, insulin resistance and increased levels of HDL as a useful indicator of cardiovascular function in men with type 2 diabetes.
