Adiponectin, a cytokine secreted from adipose tissue, is involved in the pathogenesis of obesity and insulin resistance. The aim of this study was to investigate the effect of 8 weeks of interval training with high intensity on the levels of plasma adiponectin, insulin, insulin resistance, and glucose in overweight young men. This study has a semi-experimental design, subjects were 20 overweight young men with Average age (22.95 ± 1.32) and BMI between 25 to 30 kg/m2 that purposefully selected and randomly assigned into two groups of experimental and control groups. The experimental group performed an aerobic exercise program for 8 weeks, 3 sessions per week, with 90% percent of the maximum heart beat. Research variables were measured before and after exercise. The Data were analyzed by the dependent t - test and covariance analysis at p < 0.05. The result indicated that 8 weeks of intensive interval training led to the increase of serum adiponectin level (F=88.47, P=0.03) and a Significant decrease in Insulin (F=48.38, P=0.004), insulin resistance (F=61.08, P=0.001), glucose (F=58.33, P=0.027), body mass index (F=75.12 , P=0.04), body weight (F=56.09 , P=0.02), and body fat percent (F=50.03, P=0.001) (p < 0.05). But no significant difference was observed (F=1.79, P=0.073) in the waist to hip ratio. It seems that 8 weeks of high interval training as a non-invasive treatment can increase adiponectin levels while Reduce some glycemic and anthropometric indexes related to obesity or overweight.
