THE EFFECT OF CONTINUES AND PROGRESSIVE RESISTANCE TRAINING ON SERUM ADIPONECTIN AND VASPIN CONCENTRATION AND INSULIN RESISTANCE IN OVERWEIGHT MEN

The relationship between adipokines, insulin resistance and type 2 diabetes has been well documented. However, the effect of exercise training modalities on some of the new adipokines and their association with insulin resistance is not clear. The purpose of this study was to compare the effect of endurance and progressive resistance training on serum adiponectin, vaspin and insulin resistance in overweight and obese men. 33 overweight men (mean BMI= 27.3 kg/m2) were randomly divided into 3 groups of n=11, including; 1- continues training, 2- progressive resistance training and 3-control. The training protocols was lasted to eight weeks, three days a week in continues and progressive resistance training groups. Before the beginning of the training and 72 hours after the last training session, blood samples were collected for measuring serum adiponectin, vaspin, glucose and insulin. There was a significant decrease in insulin levels and a significant increase in serum adiponectin and vaspin in both groups of continuous and progressive resistance training (P<0.05). After the training, there was a significant difference between the groups in the concentration of adiponectin (P= 0.001) and vaspin (P= 0.021). However, there was no significant difference between continuous and progressive resistance training groups in any of the variables. It seems that progressive resistance training like the endurance training, improves anti-inflammatory indices and insulin resistance of overweight and obese men.
