Growing bodies of literature have indicated an association of obesity with insulin resistance. In this study, Thirty two sedentary adult obese women (age, 38 ± 4.3 yr, BMI, 32.42 ± 3.3 kg/m2) were divided into exercise (aerobic training, 6 weeks/3 times per week) or control (without exercise) group. Fasting venous blood samples were obtained before and after exercise program for measuring insulin and glucose and insulin resistance. Student’s paired ‘t’ test was applied to compare the pre and post training values. Aerobic training decreased fasting glucose concentration in exercise group but not in the control group. Insulin resistance tended to (borderline) be decrease by aerobic training in exercise group, but did not reach statistical significance. Insulin concentration did not change with aerobic training program. Based on these data, we can say the changes in glucose concentration in response to aerobic training does not affect by insulin action only, and Can be attributed to the changes in other hormonal changes.
