Individualized blood flow constraint rehabilitation training (PBFR) is a game-changing injury recovery treatment that is producing dramatically favorable 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 Enhance muscle protein synthesis in the elderly Improve strength and hypertrophy after surgery Improve muscle activation Boost growth hormonal agent actions.
Muscle weakness commonly happens in a variety of conditions and pathologies. High load resistance training has actually been shown to be the most successful ways in enhancing muscular strength and obtaining muscle hypertrophy. The issue that exists is that in certain populations that need muscle reinforcing eg Chronic Discomfort Patients or post-operative patients, high load and high intensity workouts might not be scientifically suitable.
Blood Flow Constraint (BFR) training is a technique that integrates low intensity exercise with blood circulation occlusion that produces comparable results to high strength training. It has been utilized in the fitness center setting for a long time but it is getting appeal in scientific settings. Blood Flow Restriction (BFR) Training [modify edit 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 pumped up to a particular pressure with the objective of acquiring partial arterial and total venous occlusion. Muscle hypertrophy is the boost in diameter of the muscle as well as a boost of the protein content within the fibres.
Muscle stress and metabolic tension are the two primary aspects accountable for muscle hypertrophy. Mechanical Tension & Metabolic Tension [modify edit source] When a muscle is placed under mechanical stress, the concentration of anabolic hormonal agent levels increase. The activation of myogenic stem cells and the raised anabolic hormonal agents result in protein metabolism and as such muscle hypertrophy can happen.
Insulin-like growth factor and growth hormone are accountable for increased collagen synthesis after exercise and aids muscle recovery. Growth hormonal agent itself does not directly trigger muscle hypertrophy but it helps muscle recovery and therefore possibly helps with the muscle reinforcing process. The accumulation of lactate and hydrogen ions (eg in hypoxic training) additional boosts the release of development 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.
This leads to a boost in anaerobic lactic metabolism and the production of lactate. When there is blood pooling and an accumulation of metabolites cell swelling happens. This swelling within the cells causes an anabolic reaction and results in muscle hypertrophy. The cell swelling may actually trigger mechanical tension which will then activate the myogenic stem cells as gone over above.
The cuff is placed proximally to the muscle being exercise and low strength exercises can then be carried out. Due to the fact that the outflow of blood is limited utilizing the cuff capillary blood that has a low oxygen content gathers and there is an increase in protons and lactic acid. The very same physiological adjustments to the muscle (eg release of hormones, hypoxia and cell swelling) will happen throughout the BFR training and low strength workout as would take place with high intensity exercise.
( 1) Low intensity BFR (LI-BFR) leads to a boost in the water material of the muscle cells (cell swelling). It also accelerates the recruitment of fast-twitch muscle fibers. It is also assumed that once the cuff is gotten rid of a hyperemia (excess of blood in the blood vessels) will form and this will trigger additional cell swelling.
These boosts were similar to gains acquired as a result of high-intensity workout without BFR A study comparing (1) high intensity, (2) low intensity, (3) high and low intensity with BFR and (4) low intensity with BFR. While all 4 workout regimes produced increases in torque, muscle activations and muscle endurance over a 6 week period - the high strength (group 1) and BFR (groups 3 and 4) produced the biggest result size and were similar to each other.
