عنوان مقاله [English]
Adipose tissue has an important role through the production and secretion of abnormal proteins such as leptin, adiponectin and resistin in insulin resistance. The aim of this study was to investigate the effect of a periodof aerobic training on serum resistinlevel in obese men.
Materials and Methods
Twenty obese men were selected voluntarily and were included randomly in the experimental (N=10) and control (N=10) groups. Aerobic training protocol consisted of 3 sessions per week for 10 weeks. Each training session consisted of one slow running with intensity of 65 to 75 percent of maximal heart rate for a period of 10 minutes. In accordance to principle of overload, half-a-minute was added to each session, so that, at the last session the running time reached to 25 minutes. Before and after the training period, blood sampling was performed. Data were analyzed using independent t-test.
Results showed that there was no significant difference in serum level of resistin and insulin resistance index between the control and experimental groups. However, aerobic training reduced significantly body mass index, body weight, waist to hip ratio, body fat percentage, and increased significantly the maximum oxygen uptake.
It can be said that 10 weeks of aerobic training had no effect on serum resistin levelin obese men. However, to achieve more conclusive results, further investigation was warranted
