Abstract
The purpose of this study was the effect of eight weeks of circuit training on the Irisin levels and

the Insulin Resistance Index (HOMA-IR) in overweight women. Materials and Methods: In this study 22

overweight women voluntarily were chosen (Age 26.04±4.43 yrs, BMI 29.35±2.53 kg/m2) and were divided

to two groups of control (n=11) and experimental (n=11). In the experimental group, subjects performed

circuit training for eight weeks and four times per week. Blood sample was taken before and 48 hours after

the last training session. Statistical analysis at the level of P<0.05 was done. Findings: After eight weeks of

training, the level of Irisin in experimental group significantly increased while the HOMA-IR had a

significant reduction (p<0.05). Also Pearson correlation co-efficiency test shows that there is a reverse

relationship between irisin and HOMA-IR (P≤0.05). Conclusion: It appears that circuit training improves

body composition and metabolic disorders such as insulin resistance through Irisin induction in overweight

women.
