Key result
Cycling with blood flow restriction at 60% and 80% of limb occlusion pressure significantly reduced blood flow by ~33% and ~50% respectively compared to low-load cycling without restriction.
Why the study?
Aerobic exercise with blood flow restriction can improve muscular function and aerobic capacity, but how cuff pressure influences acute physiological responses is not well documented.
Does low-load cycling with blood flow restriction alter physiological and neuromuscular responses compared to low-load and high-load cycling without restriction?

Does low-load cycling with blood flow restriction alter physiological and neuromuscular responses compared to low-load and high-load cycling without restriction?
Effect estimate: reduced by ~33% (BFR60) and ~50% (BFR80)
p-value: p=<0.05
Cycling with blood flow restriction at moderate pressure (60% limb occlusion) increases metabolic stress and impairs neuromuscular function similarly to high-load cycling but without causing severe pain, suggesting it as a potential alternative to high-intensity aerobic exercise.
Kilgas et al. (2022) conducted an RCT in Healthy active men (n=10). Low-load cycling with blood flow restriction (BFR) vs. Low-load cycling without BFR and high-load cycling without BFR was evaluated on Blood flow during recovery periods (reduced by ~33% (BFR60) and ~50% (BFR80), p=<0.05). Cycling with blood flow restriction at 60% and 80% of limb occlusion pressure significantly reduced blood flow by ~33% and ~50% respectively compared to low-load cycling without restriction.
