| Abstract: |
| Aim and Background: Anterior cruciate ligament (ACL) injury is associated with changes in some factors related to metabolism and muscle atrophy such as silent information regulator T1 (SIRT1), visfatin and nitric oxide (NO). Thus, porpuse of this study was to investigate the effects of blood flow restriction (BRF) and electrical stimulation (EMS) on this cellular hypertrophic factors in elite male athletes after ACL reconstruction surgery. Methodology: Thirty elite male athletes after anterior cruciate ligament surgery were selected and randomly divided into three groups of 1) BRF, 2) EMS and 3) control groups (10 subjects in each group). The subjects in BRF group performed resistance training with cuff pressure on the proximal part of the thigh with 120-180 mmHg for 12 weeks. However, The subjects in EMS group performed 12 weeks of resistance training along with electrical stimulation at frequency of 35-70 Hz. The subjects in control group participated in 12 weeks of resistance training [2-4 sets, at intensity of 30-70 percent of 10 repetition maximum (RM)] without no intrvention else. Blood factors were assessed before and 48 hours following last training session. Statistical analysis was done by analysis of Covariance and paired t-test at significant level of P<0.05. Results: There were significant differences between training groups of BFR and EMS and control groups in SIRT1 (P=0.00) and NO (P=0.002) concentrations. Moreover, twelve weeks of BRF and EMS resulted to significant increases in serum levels of SIRT1 (P=0.00), visfatin (P=0.043, P=0.02, respectively) and NO (P=0.001, P=0.01, respectively) compared to pre-test. Conclusion: Overall, it seems that both of EMS and BRF are more effective protocols compared to traditional resistance training to improve muscle atrophy following disuse and injury in elite athletes. |
