Key result
Very low load resistance training with high-pressure blood flow restriction increased upper body vascular conductance (+8.29 ml·mmHg−1) significantly more than low-pressure conditions.
Why the study?
To investigate vascular adaptations in the upper and lower body to resistance exercise performed with and without different pressures of blood flow restriction.

High-pressure BFR during very low-load training may augment vascular conductance; hypothesis-generating and should not change practice.
Absolute Event Rate: 8.29% vs -0.41%
Mouser et al. (2019) studied this question. Very low load resistance training with high-pressure blood flow restriction vs. Low-pressure BFR (40% AOP), no BFR, and high-load (70% 1RM) resistance training was evaluated on Pre to post change in upper body vascular conductance (ml·mmHg−1). Very low load resistance training with high-pressure blood flow restriction increased upper body vascular conductance (+8.29 ml·mmHg−1) significantly more than low-pressure conditions.
