Key result
Low load resistance training with blood flow restriction increased peak reactive hyperemia (1,400 to 1,716 ml/min; P=0.047) and transiently improved popliteal FMD% (P=0.002).

Supports transient vascular adaptations with low-load BFR in healthy males; hypothesis-generating and requires randomized confirmation before practice change.

Absolute Event Rate: 1716% vs 1400%
p-value: p=0.047
Low load resistance training with blood flow restriction induces early and transient vascular adaptations at the conduit, resistance, and capillary levels.
Hunt et al. (2013) studied this question. Low load resistance training with blood flow restriction vs. Contralateral nonexercised control leg was evaluated on Peak reactive hyperemia at 2 weeks (p=0.047). Low load resistance training with blood flow restriction increased peak reactive hyperemia (1,400 to 1,716 ml/min; P=0.047) and transiently improved popliteal FMD% (P=0.002).
