Background: This study was conducted to determine the effect of 12 weeks of aerobic training on serum levels of vaspin and glucose homeostasis variables in patients with type 2 diabetes. Methods: In this quasi-experimental study, 20 women with type П diabetes (mean±SD: age 43.30 ±3.02 yr, body mass index 27.089±3.23 kg/m2 and body fat 29.46 ±2.71%) were randomized into experimental (n = 10) and control (n = 10) groups. Experimental group performed twelve weeks aerobic training (3 times per week at an intensity of 75-85 % of maximum heart rate reserve). Blood samples were collected 24h before and 48h after the training. Data was analyzed by paired and independent samples t-test (P <0.05). Results: Results showed a significant decrease in serum levels of vaspin, fasting blood sugar and insulin resistance index (P value 0.001, 0.01 and 0.007 respectively) ) in experimental group and body weight, body mass index, percent body fat and waist to hip ratio significantly decreased in experimental group (P value 0.002, 0.01, 0.04 and 0.03 respectively). Conclusion: The results of this study showed that aerobic training along with decrease in body weight and percent body fat leads to significant decrease in serum levels of vaspin, fasting glucose and insulin resistance index, so can be considered as a complementary therapy method in patients with type 2 diabetes.
