Abstract: Background and Objectives: Resistance training with vascular occlusion is a type of resistance training, which causes various changes through blood flow restriction in muscular function and hormonal responses. The purpose of the current study was to compare between the effects of low-intensity resistance training with vascular occlusion and high-intensity traditional resistance training on resting growth hormone (GH) levels in active females. Methods: In this semi-experimental study, 34 female students (age range, 20.7±1.3 years; weight, 58.4±1.3kg; height, 164.1±0.9cm; and BMI, 23.1±0.5kg/m2), were randomly divided into three groups of traditional resistance training (IRM, 75%; n=12), resistance training with vascular occlusion (IRM, 30%; with wrapping a rubber tourniquet around the proximal arm; n=11), and control (n=11). Blood sampling was performed before the start of training and 48 hours after the last training session. Training included 3 sets of 10-front arm extension, 3 sessions per week for 6 weeks. Data were analyzed using dependent t- and one-way ANOVA tests. Results: After 6 weeks of training, the resting GH levels had a significant increase in both experimental groups compared to the control group (p<0.05). Conclusion: Recent study partially supports the effectiveness of resistance trainings with blood flow restriction. Therefore, low-intensity resistance trainings with blood flow restriction can be replaced instead of traditional high-intensity resistance trainings for young females.
