Key result
Bilateral blood flow restriction at 60% during repeated cycling sprints decreased total work by 68.6% and V̇O2peak by 18.2% compared to 0% restriction (P<0.01).

High-pressure BFR impairs repeated sprint capacity; leaves open its role in training or rehabilitation protocols.
Does bilateral blood flow restriction alter oxygenation and neuromuscular fatigue during repeated cycling sprints?
p-value: p=< 0.01
Blood flow restriction during repeated sprint exercise decreases total work and V̇O2peak while inducing greater changes in tissue perfusion and neuromuscular fatigue.
Willis et al. (2018) studied this question. Bilateral blood flow restriction vs. 0% restriction was evaluated on Total work (p=< 0.01). Bilateral blood flow restriction at 60% during repeated cycling sprints decreased total work by 68.6% and V̇O2peak by 18.2% compared to 0% restriction (P<0.01).
