Abstract

Several studies have supported the efficacy of low-intensity resistance training (15-50% of one repetition maximum) with vascular occlusion in promoting increased muscle mass and strength similar tothose observed after high-intensity resistance training. However, little is known regarding the dose-response of acute variables of low-intensity resistance training with blood flow restriction on muscle mass and strength. This review investigated the impact of intensities and volumes of low intensity resistance training with blood flow restriction as well as fitness status of subject on the adaptation of muscle strength and size. This revision was controlled for gender, assessment method of hypertrophy (only use MRI-measured muscle size data), exercise (leg extension) and muscle (quadriceps). The few selected studies related increase in cross section area of quadriceps. There was correlations (r2 = 0.71, P = 0.034) between fitness status and hypertrophy. There were not correlations between hypertrophy and intensity (r2 = 0.54, P = 0.098), volume (r2 = -0.03, P = 0.742) or frequency of training (r2 = -0.13, P = 0.488). A modest amount of selected studies supports hypertrophic effect of low-intensity resistance training with vascular occlusion. However, hypertrophy seems to be dependent on the fitness level of individuals, but it is not to intensity, volume, and frequency of training.
