Background and Aims

Many studies have been conducted with a high degree of variability in the response to insulin-like growth factor-1 and myostatin in various exercise trainings. Therefore, the aim of the current study was to survey the acute effect of resistance training with and without blood flow restriction on the muscle hypertrophy indicators.

Materials and Methods

A total of 30 female basketball players with the age range of 23-30 years were randomly divided into three groups (10 athletes in each group): traditional resistance training (80% 1RM), resistance training with blood flow restriction (30% 1RM), and control group (blood flow restriction without exercise). The exercise started with a set of 30 repetitions and ended with two sets of repetitions until fatigue with a 30-second rest period. Blood samples were taken before and immediately after the exercise. Paired sample t-test was used to compare intra-group changes and one-way ANOVA was used to compare between group changes.

Results

Intra-group changes indicated no significant change in serum levels of insulin-like growth factor-1 (P>0.05) and a significant decrease in myostatin (P<0.05) in the two training groups as compared to the pretest. In between group comparison, there was a significant increase only in myostatin levels in both training groups compared to the control group (P<0.05).

Conclusion

Based on the results, the effect of blood flow restriction exercise training on serum levels of insulin-like growth factor-1 and myostatin in female athletes was similar to that of exercise training without blood flow restriction. It seems that for those who are in rehabilitation period or cannot lift heavy weight, low intensity resistance training with blood flow restriction can be used instead of high intensity resistance training.
