Effect of 8 weeks sprint interval training on serum levels of Adiponectin and insulin in overweight children

Scientific studies demonstrated that decreased blood Adiponectin level is associated with insulin resistance in obesity. Also it is well documented that exercise training exerts beneficial effects on obesity but there is few study regarding beneficial effects of sprint Interval training (SIT) on childhood obesity. This study was intended to investigate the effect of SIT on serum levels of Adiponectin and insulin in overweight children.
Material and In this study thirty-two obese boy (BMI=27) were randomly assigned to sprint Interval Training (SIT) (N=16) and control group(C) (N=16). Training protocol consisted of 30s and 90s all-out running that performed 3 sessions per week for 8 weeks. Blood samples were measured by ELISA analysis. Data were analyzed using Independent sample t-test.
8 weeks SIT increase serum levels of Adiponectin (P=0.028) and decrease insulin level (P=0.00). This change was directly related to decrease in values of BMI (P=0.01), total cholesterol (P=0.00) and body weight (P=0.02), but significant change in serum levels of HDL (P=0.50), LDL (P=0.17) and TG (P=0.60) wasn’t observed.
These findings suggest that SIT may ameliorate the metabolic abnormalities associated with obesity in children probably through elevation of serum Adiponectin level.
