The Effect of Eight Weeks Pilates Training on Irisin Serum Levels and Insulin Resistance Index in Obese Women

  Irisin is a novel myokine, adipokine and neurokine that recently discovered in humans and mice.
Evidence suggests that Irisin is associated with obesity and diabetes. The purpose of this study was to determine the effect of 8-weeks Pilates training programs on serum irisn levels and insulin resistance index in obese
women. This research is a semi experimental study with pre-and post-test Design. In this quasiexperimental study, 24 obese women (mean age 38/4±8/61 years and BMI 35/6±2/95 kg/m2) volunteered to participate in this study and were randomly divided into Pilates group (n=15) and control group (n=9). Pilates training program performed in 8 weeks, 3 times per week, and 14-16 RPE While the control group did not exercise. Blood samples were obtained before and after training to measure glucose, insulin, insulin resistance and Irisin. Data were analyzed with paired-sample t-test and ANCOVA. The results indicated no significant changes in blood glucose (p=0.44), insulin (p=0.81), insulin resistance index (p=0.85) and serum Irisin levels(p=0.86) in Pilate’s group compared with the control group after 8 weeks (p>0.05). Furthermore, correlation was not between Irisin to BMI, weight, glucose, insulin, and insulin resistance index (p≥0.05). The results were showed increase VO2max after the Pilates exercises(p<0.05) This finding revealed that 8 weeks Pilates training cannot be considerable impact on glucose, insulin, insulin resistance index and
serum Irisin levels in obese women.
