Accumulating evidence indicates that obesity and overweight are associated with insulin resistance; however, the precise mechanisms of any association between them have not yet been established. This study is designed to evaluate acute and recovery response of insulin resistance to an exercise test in adult obese men. For this purpose, twenty sedentary healthy obese men aged 37 – 44 years, 30 – 35 kg/m2 of BMI were enrolled for participation in this study. Venous blood samples were collected before, 0, 1 and 24 hours after single bout running test for 45 min in order to measuring glucose and insulin. Insulin and glucose levels were used for the homeostasis model assessment of insulin resistance. Repeated measures ANOVA method was used to analysis. Glucose concentration decreased immediately and 1 hour after exercise test and return to baseline levels after 24 hours. Serum insulin and insulin resistance decreased immediately after exercise, but return to baseline levels after 1 hour. Based on these data, we can say 45 min running for one session is associated with acute decreased in glucose and insulin resistance not recovery response in obese men.
