The effect of exercise training in water on serum adiponectin and insulin resistance in obese children and adolescents

The aim of this study was to determine the effect of exercise training in water on serum adiponectin and insulin resistance in obese children and adolescents. For this purpose 60 obese subjects (children 10-12 years and adolescents 14-16 years) were randomly assigned into one of four groups: exercise training in water for both children and adolescents, and control groups (children and adolescents). Experimental groups underwent exercise training for 8 weeks; 3 sessions per week and 60 minutes per session, with an intensity of 60-85% of maximum heart rate. Blood samples, anthropometric and body composition measures were taken before and after training program. Data analysis using ANOVA showed that exercise training in water caused a significant decrease in body fat percent, and increase in VO2max in the children and adolescents. Exercise training in water had no effect on serum adiponectin and insulin resistance. In summary, since 8 weeks exercise training in water did not cause weight loss, it probably had no effect on adiponectin and insulin resistance.
