![]() ![]() Some studies have shown improved strength in quadriceps strength after ACL surgery. It can promote early increases in strength while minimizing disruption to repaired or damaged tissue. Where I feel that BFR may ultimately play a greater role, however, is recovery from surgery or injury. Thus, it be used to augment a traditional resistance training method but should not completely supplant it.īelow is a video that demonstrates the use of BFR in a college football athlete during a variety of exercises. However, BFR has not been shown to recruit the degree of muscle units as high load training methods. Several studies have looked at rugby athletes, college football athletes, and college basketball athletes with overall increases in knee extension strength, endurance, 1 RM bench press, VO2 max, and squat strength. ![]() When BFR has been studied in the setting of athletic performance training, most studies have shown improvement in strength. However, in the clinical setting, most people use a more practical approach, in which the pressure is set at some number below AOP. It is reported that 40% of this pressure can be used for effective gains. This is the pressure required to occlude all arterial blood flow into a limb. One can actually base the pressure on one’s arterial occlusion pressure (AOP) to individualize it. However, recent studies show similar results with pressures as low as 50 mm Hg. Initially, when BFR was initiated, pressures greater than 200 mg Hg were used. This in turn leads to increased muscle strength, hypertrophy, and angiogenesis (new blood vessels). This leads to increase in protein synthesis, type 2 muscle fibers, local and systemic hormones, and myogenic stem cells. The metabolic stress coupled with mechanical tension results in hypoxia (low oxygen environment), cellular swelling, and release of metabolites such as lactic acid and reactive oxygen species. How does it work? There are several mechanism by which BFR is thought to work. ![]() However, low load resistances can stimulate anabolic pathways. Traditional strength straining entails using loads greater than 70% of one rep max to stimulate muscle growth. It was originally described and developed in Japan in the late 1970s and was referred to as KAATSU training.īFR therapy refers to a method by which venous outflow on a limb is reduced to enhance strength gains and hypertrophy of muscle. Blood flow restriction (BFR) therapy is growing in prevalence in gyms, athletic training rooms, physical therapy clinics, sports performance centers, and orthopedic offices. ![]()
