Owens Recovery Science - Blood Flow Restriction Training

1. Individualized blood flow limitation rehabilitation training (PBFR) is a game-changing injury healing treatment that is producing drastically positive outcomes: Diminish atrophy and loss of strength from disuse and non-weight bearing after injuries Boost strength with only 30% loads Increase hypertrophy with only 30% loads Enhance muscle endurance in 1/3 the time Enhance muscle protein synthesis in the elderly Improve strength and hypertrophy after surgical treatment Improve muscle activation Increase development hormonal agent actions. Muscle weakness frequently occurs in a range of conditions and pathologies. High load resistance training has been shown to be the most successful methods in enhancing muscular strength and getting muscle hypertrophy. The problem that exists is that in specific populations that need muscle reinforcing eg Chronic Pain Patients or post-operative patients, high load and high strength exercises may not be scientifically suitable. It has actually been used in the fitness center setting for some time but it is acquiring appeal in scientific settings. BFR training was at first developed in the 1960's in Japan and understood as KAATSU training. It can be applied to either the upper or lower limb. The cuff is then pumped up to a particular pressure with the goal of getting partial arterial and complete venous occlusion. Muscle hypertrophy is the boost in diameter of the muscle as well as a boost of the protein material within the fibers. Muscle tension and metabolic tension are the two primary factors responsible for muscle hypertrophy. Mechanical Tension & Metabolic Stress [edit modify source] When a muscle is placed under mechanical stress, the concentration of anabolic hormone levels increase. The activation of myogenic stem cells and the elevated anabolic hormones result in protein metabolic process and as such muscle hypertrophy can take place. Development hormone itself does not straight cause muscle hypertrophy but it aids muscle recovery and therefore potentially helps with the muscle strengthening procedure. The build-up of lactate and hydrogen ions (eg in hypoxic training) additional increases the release of development hormonal agent. Myostatin controls and prevents cell growth in muscle tissue. Resistance training results in the compression of blood vessels within the muscles being trained. When there is blood pooling and an accumulation of metabolites cell swelling occurs. This swelling within the cells triggers an anabolic response and results in muscle hypertrophy. The cuff is put proximally to the muscle being exercise and low intensity exercises can then be carried out. Due to the fact that the outflow of blood is restricted using the cuff capillary blood that has a low oxygen material collects and there is a boost in protons and lactic acid. The same physiological adaptations to the muscle (eg release of hormones, hypoxia and cell swelling) will take place throughout the BFR training and low intensity workout as would accompany high intensity exercise. ( 1) Low strength BFR (LI-BFR) leads to an increase in the water material of the muscle cells (cell swelling). It also speeds up the recruitment of fast-twitch muscle fibres. It is also hypothesized that as soon as the cuff is eliminated

2. a hyperemia (excess of blood in the capillary) will form and this will trigger further cell swelling. These boosts resembled gains gotten as an outcome of high-intensity exercise without BFR A study comparing (1) high intensity, (2) low intensity, (3) high and low strength with BFR and (4) low intensity with BFR. While all 4 exercise regimes produced increases in torque, muscle activations and muscle endurance over a 6 week duration - the high strength (group 1) and BFR (groups 3 and 4) produced the greatest result size and were similar to each other.
