BFR Training
Blood flow restriction training promises strength and endurance gains at low mechanical load. But does it work for runners?

How It Works
A cuff partially restricts blood flow during low-load exercise — typically 20–40% of 1RM — creating a hypoxic, metabolite-rich environment.

The Runner-Specific Evidence
Meta-analyses show moderate-to-large pooled benefits for aerobic capacity and strength. But individual studies are inconsistent.

The Fatigue Problem
A 2025 study of 15 female runners found BFR running raised heart rate and lactate — but produced the highest perceived exertion.

Safety First
Contraindications include blood clot history, peripheral vascular disease, uncontrolled cardiac conditions, severe hypertension, and pregnancy.

Pressure Matters
Guidelines recommend 50–80% of arterial occlusion, adjusted for cuff width. Individualize, don't improvise.

Bottom Line
BFR may help build strength at low joint stress, but runner-specific evidence is limited. Use it wisely.
