| Introduction: Myostatin and its inhibitor "follistatin" have been proposed as factors that could potentially modify muscle mass. The purpose of this study was to investigate the effect of 8 weeks of resistance training and TRX on myostatin and follistatin and follistatin/myostatin ratio in young women. Materials and Methods: for this purpose, 20 young women (age: 20 to 30 years, height: 159.83±44 BMI: 24.31±5.21) were randomly divided to control (n=6), resistance training (n=7), and TRX (n=7) groups. The training program for both training groups was circular training with 3 sessions per week for eight weeks. The main training was performed in seven stations including squat, leg press, chest press, leg extension, shoulder, arm back, and arm forward in both training groups. Exercise intensity initially started at 40-50% 1RM (easy training for TRX group) and increased to 60-70% 1RM (Medium intensity for TRX group). 24 hours before 1st session and 48 after 12 weeks of intervention, blood sampling was performed. myostatin and follistatin levels were measured by the ELISA method. Paired t-test was used for intra-group comparisons and ANCOVA was used for comparison between groups. results: the results of Paired t-test showed that serum levels of myostatin significantly decreased in post-test than pre-test of resistance training group (p=0.037) and serum levels of follistatin significantly increased in post-test than pre-test of resistance training group than pre-test (p=0.045), but these changes were not significant in the TRX training group (p>0.05). Eight weeks of resistance training and TRX had no significant effect on the follistatin/myostatin ratio in young women (p-value respectively 0.055 and 0.703). Also, there was no significant difference between the groups in the serum levels of myostatin, follistatin, and follistatin/myostatin (p-value respectively 0.688, 0.315, and 0.457). Conclusion: it can be concluded that Resistance training can stimulate myostatin and follistatin levels in young women, thus this training can be used as a kind of exercise intervention in rehabilitation programs and bodybuilding exercises in young people. |
