Background and Objectives: Insulin-like growth factor-1 (IGF-1) and myostatin play an important role in responding to muscle contractions, regulating and stimulating muscle metabolism. Therefore, the aim of this study was to investigate the effect of 8 weeks of resistance training with and without blood flow restriction on IGF-1 and myostatin of female athletes.
Materials and Methods: In this semi-experimental study, 33 athletic girls were randomly assigned to three groups of 11 people: 1- traditional resistance training (TRT) (at 80% 1RM), 2- resistance training with blood flow restriction (BFR) (at 30% 1RM), and 3- blood flow restriction group with no exercise. Standing barbell curl and barbell bench press exercises were performed for 8 weeks. Blood samples were taken before and 48 hours after training to assess IGF-1 and myostatin levels by ELISA. Paired t-test was used to compare within-group changes and one-way ANOVA was used to compare between-group changes. Significance level was considered p<0/05.
Results: Myostatin level significantly decreased in both training groups compared to the control (p=0.014). Whereas there was no significant difference in IGF-1 between the three groups (p=0.137).
Conclusion: Due to the similarity of the effect of BFR and TRT on serum levels of IGF-1 and myostatin protein in female athletes, it is recommended to use less intense exercise such as BFR instead of TRT to maintain health.
Key words: Resistance training, Blood flow restriction, Insulin-like growth factor-1, Myostatin, Athletic girls
