Acute And Chronic Vascular Responses To Blood Flow Restriction In The Upper Body, J. Grant Mouser

Electronic Theses and Dissertations

Blood flow restriction (BFR) with low load exercise increases muscular size and strength. Little is known of vascular adaptations to this training modality, and nothing was known at very low loads. These studies examined cardiovascular responses to high load (70% of one-repetition maximum (1RM)) and very low load (15%1RM) exercise, alone or at two levels of BFR. Study 1: Participants performed unilateral biceps curls using either 15%1RM with no BFR (15/00), 40% of arterial occlusion pressure (AOP) (15/40), or 80%AOP (15/80), or 70%1RM (70/00). Systolic and diastolic blood pressure (SBP, DBP) and blood flow (BF) were measured in the arms …
