Abstract
A sedentary lifestyle is associated with a decline in muscle mass, bone density, and cardiovascular fitness (CVF), and functional capacity which leads to a decline in health-related factors and regular exercise has been shown to reduce or reverse these effects. Blood flow restriction (BFR) is a novel mode of low-intensity exercise that has been shown to accelerate exercise-induced benefits.
Purpose: The purpose of this study was to assess the effects of 7-weeks of BFR endurance training on CVF and functional capacity in sedentary individuals.
Methods: Participants (n=7) visited twice (separated by at least 24 hours) a week for seven weeks. On training days subjects cycled on a recumbent bike with BFR cuffs placed bilaterally at a percentage of arterial occlusion pressure (AOP) (treatment 60%, control 5%). On testing days (pre, mid, and post), resting blood pressure (BP), heart rate (HR), and bioelectrical impedance analysis (BIA) and AOP were measured. Subjects then performed a 10-minute walk test to assess fatigability, wearing an HR monitor in order to measure HR at each lap. Perceived fatigue was reported pre and post-walk tests. The distance was measured every 2.5 minutes from which performance fatigue was calculated.
