Introduction: One of the causes of diabetes are obesity, on the other hand do resistance training increases insulin action in skeletal muscle and improves glucose tolerance.

 Materials and Methods: In this study was to investigate the effects of resistance training along with glycemic indices using cinnamon on obese men, 40 young men and obese people were randomly divided into 4 groups (supplements, practice, practice + Supplement control) groups. Supplementation and exercise + 3 capsules daily supplement of 380 mg for 8 weeks received cinnamon, exercise group and the control's taking placebo. Of all the subjects before and after the 8 week study protocol for measuring blood glucose and insulin levels and insulin resistance index, blood samples were taken. Data were analyzed with ANOVA andT-test.

Results: Glucose and insulin resistance exercise group and exercise + supplement and complement lower than the control group, but there was no significant difference among the four groups.

Conclusion: Resistance training alone with cinnamon and also taking cinnamon supplements alone will not affect the glycemic index.
