Background: Irisin was identified as a myokine secreted by exercise which plays an important role in energy metabolism and regulation of metabolic diseases such as diabetes. The aim of the present study is to investigate the effects of high intensity interval exercise (HIIE) and moderate intensity continuous exercise (MICE) on serum irisin and Subcutaneous UCP-1 in diabetic male rats.

Methods: In this study, 29 diabetic Wistar rats (12 week- age, 220-240 gr- weight) were assigned to 5 groups: immediately and 2 hours after high intensity interval exercise (HIIE0, HIIE2), immediately and 2 hours after moderate intensity continuous exercise (MICE0, MICE2) and control (C). Both MICE groups performed on the treadmill with intensity 60-65% vo2max for 40 minutes and both HIIE groups with intensity 90-95% vo2max in the 12 interval-one minute period and 1 minute rest intervals. ELISA was used to measure serum irisin and subcutaneous fat UCP-1. One-way ANOVA and Tukey post hoc test has used to data analysis, the level of significance has been considered at P≤0/05.

Results: Data analysis showed serum irisin levels in the HIIE0 group and subcutaneous fat UCP-1 in the HIIE2 significantly increased compared to the control group (p˂0/05). However, there was no significant difference between other research groups (P>0/05).

Conclusion: It seems high intensity of exercise had important roles in significant changes of serum irisin levels and subcutaneous fat UCP-1in diabetic rats.
