Four weeks of arm-curl training with or without blood flow restriction significantly increased muscle strength and thickness in young, healthy humans.
RCT (n=22)
Does the blood flow restriction (BFR) technique increase the blood pressure response during arm-curl exercise in young, healthy humans?
Blood flow restriction during resistance exercise intensifies the blood pressure response, which is linked to the muscle metaboreflex.
Absolute Event Rate: 14.1% vs 12.8%
p-value: p=<0.01
Some researchers are concerned that exercise training with the blood flow restriction (BFR) technique induces an exaggeration in blood pressure response and potentiates adverse cardiovascular events. In the present study, we demonstrate that the blood pressure response to arm-curl exercise was intensified by the BFR technique, and the degree of intensification was associated with a blood pressure response to postexercise muscle ischemia of the elbow flexors, which elicit a muscle metaboreflex. Novelty: BFR technique intensifies blood pressure response to exercise, which was associated with a blood pressure response in postexercise muscle ischemia-induced muscle metaboreflex.
Hori et al. (Tue,) conducted a rct in Healthy (n=22). Blood flow restriction (BFR) resistance exercise vs. Control (arm-curl training without BFR) was evaluated on One-repetition maximum (1RM) of single arm-curl after 4 weeks (Kg) (p=<0.01). Four weeks of arm-curl training with or without blood flow restriction significantly increased muscle strength and thickness in young, healthy humans.
