Background and Objective: Body composition and balance are always one of the main factors of health and quality of life among the people. The purpose of this study was to compare the effect of resistance training with TRX and Traditional on some factors of body composition and balance in Sedentary men.
Subjects and Methods: InThis semi-experimental study, thirty Sedentary men (age = 29/33±3.23 and BMI = 26/03±1.24) participated and randomly divided to TRX group (n = 15) and traditional group (n = 15). Befor and after eight weeks of training, body composition (weight, BMI and percentage of body fat) and balance in three position (two legs, right leg and left leg) with Biodex stability system evaluated.
Results: It was not observed any difference between groups in body composition (P>0/05); but the weight, BMI and percentage of body fat in traditional group and only percentage of body fat in TRX group significantly decreased (P<0/05). According to between group results, the overall balance of two legs and left leg and also ML balance of two legs, right leg and left leg in TRX group was significantly better than traditional group (P<0/05). While, ML balance of two legs and right leg had significant improvement only after TRX training (P<0/05), after traditional training, it was observed a significant decrease in overall and AP balance of right leg (P<0/05).
Conclusion: It is consider that to compare with traditional resistance training, resistance training with TRX can be more effective in balance (not in body composition).
