Owens Recovery Science - Blood Flow Restriction Training

Posted by Roseline on August 3rd, 2021

Personalized blood circulation restriction rehabilitation training (PBFR) is a game-changing injury healing treatment that is producing dramatically positive results: Reduce 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 Improve muscle protein synthesis in the senior Improve strength and hypertrophy after surgical treatment Enhance muscle activation Boost development hormone responses.

Muscle weak point commonly takes place in a range of conditions and pathologies. High load resistance training has been shown to be the most successful means in enhancing muscular strength and getting muscle hypertrophy. The problem that exists is that in specific populations that require muscle reinforcing eg Chronic Discomfort Patients or post-operative clients, high load and high strength workouts may not be scientifically suitable.

Blood Flow Limitation (BFR) training is a strategy that combines low strength exercise with blood flow occlusion that produces similar outcomes to high strength training. It has been used in the fitness center setting for a long time however it is acquiring popularity in medical settings. Blood Flow Restriction (BFR) Training [modify modify source] BFR training was at first established in the 1960's in Japan and referred to as KAATSU training.

It can be used to either the upper or lower limb. The cuff is then inflated to a specific pressure with the aim of acquiring partial arterial and complete venous occlusion. The client is then asked to perform resistance exercises at a low strength of 20-30% of 1 repeating max (1RM), with high repeatings per set (15-30) and brief rest intervals between sets (30 seconds) Comprehending the Physiology of Muscle Hypertrophy. [edit edit source] Muscle hypertrophy is the boost in size of the muscle along with a boost of the protein content within the fibers.

Muscle stress and metabolic stress are the two primary aspects accountable for muscle hypertrophy. Mechanical Tension & Metabolic Tension [modify modify source] When a muscle is positioned under mechanical tension, the concentration of anabolic hormone levels increase. The activation of myogenic stem cells and the raised anabolic hormonal agents result in protein metabolism and as such muscle hypertrophy can occur.

Insulin-like development factor and growth hormone are accountable for increased collagen synthesis after exercise and aids muscle recovery. Development hormone itself does not directly trigger muscle hypertrophy but it aids muscle recovery and therefore possibly facilitates the muscle strengthening process. The build-up of lactate and hydrogen ions (eg in hypoxic training) additional boosts the release of growth hormonal agent.

Myostatin controls and prevents cell development 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 takes place. This swelling within the cells triggers an anabolic reaction and results in muscle hypertrophy.

The cuff is placed proximally to the muscle being exercise and low strength exercises can then be performed. Because the outflow of blood is limited using the cuff capillary blood that has a low oxygen content collects and there is a boost in protons and lactic acid. The very same physiological adaptations to the muscle (eg release of hormonal agents, hypoxia and cell swelling) will take location during the BFR training and low intensity exercise as would accompany high strength exercise.

( 1) Low strength BFR (LI-BFR) leads to an increase in the water material of the muscle cells (cell swelling). It also accelerates the recruitment of fast-twitch muscle fibers. It is likewise assumed that once the cuff is gotten rid of a hyperemia (excess of blood in the capillary) will form and this will cause additional cell swelling.

These boosts were comparable to gains acquired as a result of high-intensity exercise without BFR A study comparing (1) high strength, (2) low strength, (3) low and high strength with BFR and (4) low intensity with BFR. While all 4 exercise routines produced boosts in torque, muscle activations and muscle endurance over a 6 week period - the high intensity (group 1) and BFR (groups 3 and 4) produced the greatest effect size and were equivalent to each other.
