Blood Flow Restriction Training Blood flow restriction (BFR) training is the practice of reducing blood flow to a working muscle during exercise to allow for greater strength and hypertrophy gains while using lower resistance loads. This decrease in load in turn allows the injured, post-operative, or load compromised individual to accelerate their recovery.
BFR is performed through the application of a compression cuff around the upper arm or upper leg. A doppler ultrasound compression unit then determines the individuals personalized occlusion pressure and sets the proper percentage for training. Exercises are performed while the cuff is inflated creating a hypoxic environment in the muscles. This in turn produces metabolic, hormonal, and overall physiological changes which allow for the promotion of muscle growth and strength while under low loads. BFR training can achieve strength gains at 20-35% of ones one repetition max while traditional exercising requires twice this amount.
