Low-Load Blood Flow Restriction Training Enhances Brachial Blood Flow During Exercise but not Reactive Hyperemia in Experienced Climbers.

ABSTRACT: Low-load blood flow restriction training (LLBFRT) induces significant vascular stress, which is often associated with vascular remodeling, increased capillarization and muscle blood flow. These adaptations may be of interest to climbers as their endurance performance is limited by blood supply due to the isometric and intermittent nature of finger flexors (FD) contraction. This study, thus, aimed to assess vascular adaptations to a 5-week FD protocol using LLBFRT (n = 12, cuff pressure = 60% of the limb occlusion pressure) and compare these responses to those elicited by high-load resistance training (HLRT, n = 12) and no specific training (CON, n = 12) in male climbers. Participants in LLBFRT and HLRT trained twice a week, respectively at ~40% and ~75% of maximal voluntary contraction (MV
