Effects of resistance versus endurance training on serum adiponectin and insulin resistance index . PURPOSE The purpose of the present study was to investigate the effects of resistance and endurance training on serum adiponectin and insulin resistance index ( SI ) in healthy men . METHODS Twenty-four healthy males ( age , 35-48 years ) participated in the study . The subjects were randomly assigned to one of three groups : endurance training group ( n=8 ) , resistance training group ( n=8 ) and control group ( n=8 ) . Blood samples were taken in fasting state from all subjects . The experimental groups performed either endurance or resistance training 3 days a week for 12 weeks . The endurance training programme included continuous running at an intensity corresponding to 75-85 % of maximal heart rate , while resistance training consisted of four sets of circuit weight training for 11 stations and at an intensity corresponding to 50-60 % of one-repetition maximum . The maximum numbers of repetitions in each station was 12 . RESULTS There were significant negative correlations between serum adiponectin and body fat percentage , waist-to-hip ratio , body mass index and the insulin resistance index at baseline , whereas changes in response to training were not significantly correlated . Both endurance and resistance training resulted in a significant decrease in the SI in comparison with the control group . However , serum adiponectin did not change significantly in response to resistance and endurance training . CONCLUSION Endurance and resistance training caused an improvement in insulin resistance in healthy men , but this improvement was not accompanied by increased adiponectin levels .
