BFRT is a method for individuals recovering from surgery, injury, or the elderly populations who are not candidates for or unable to perform higher load training. BFRT, in combination with low load training, allows individuals to obtain similar gains as high intensity training (HIT).
Blood flow restriction (BFR) allows patients who are unable to perform high load exercises recover through recruitment of both slow and fast twitch fibers, where normally just the slow twitch fibers are working, creating substantial strength and muscle growth effects while exercising at light loads. These individuals will be coming off extended periods of disuse which will cause them to lose muscle.
