Abstract: Blood flow restriction during resistance exercise is an effective method for increasing muscular size and strength. However, skeletal muscle adaptations to low-load resistance exercise (LL-RE) and low-load blood flow restriction resistance exercise (LL-BFR) performed to repetition failure are lacking. Whole-body and skeletal muscle physiological outcomes were measured following 6-weeks of LL-RE and LL-BFR training to repetition failure using a within-subject design. Similar muscle strength and size outcomes occurred despite lower total exercise volume with LL-BFR. Both groups increased power output during the first-third of an endurance task and only LL-BFR training sustained a greater power output during the midpoint by 18%. Capillary contacts of type I muscle fibers increased similarly for both groups and only LL-RE training increased mitochondrial respiratory capacity by 20%. Overall, differences in muscle fatigue between LL-RE and LL-BFR may exist and are not explained by muscular strength and size or muscle microvascular and mitochondrial properties.
