Abstract
The purpose of the present study was to examine the effect of 8 weeks resistance training on the myostatin plasma level in untrained overweight men. This research was semi experimental. For this reason, 19 overweight untrained men voluntarily participated in this study and randomly were assigned to resistance training with mean of age 21±1/57 yr, height 171/11±5/51 cm, weight 92/22±15/85 kg and BF% 1/37±28/21 و35±2,2yr) or control with mean of age 21/44±1/13 yr, height 175/61±5/09 cm, weight 90/00±14/05 and BF% 2/68±27/15. The training protocol consisted, 3 sessions per week, 5 exercises, at 50-80% of 1RM for whole-body exercise for 8 weeks. Prior to study start time, and after 48 h of the last session, 5 ml plasma were collected from antecubital vein of subject..The results of independent t-test showed that there are significant decrease in plasma in experimental group (p=0/005). Therefore, it can be concludes that resistance training can prevent the loose of muscle mass and sarcopenia.
