Individualized blood flow restriction rehab training (PBFR) is a game-changing injury recovery therapy that is producing significantly positive outcomes: Lessen atrophy and loss of strength from disuse and non-weight bearing after injuries Increase strength with only 30% loads Increase hypertrophy with only 30% loads Improve muscle endurance in 1/3 the time Enhance muscle protein synthesis in the elderly Improve strength and hypertrophy after surgery Enhance muscle activation Boost development hormonal agent actions.
Muscle weak point commonly takes place in a range of conditions and pathologies. High load resistance training has been shown to be the most effective ways in enhancing muscular strength and acquiring muscle hypertrophy. The problem that exists is that in specific populations that require muscle enhancing eg Chronic Pain Clients or post-operative patients, high load and high strength workouts may not be medically appropriate.
It has been used in the gym setting for some time however it is acquiring appeal in scientific settings. BFR training was initially established in the 1960's in Japan and known 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 obtaining 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 stress and metabolic tension are the 2 primary factors responsible for muscle hypertrophy. The activation of myogenic stem cells and the raised anabolic hormonal agents result in protein metabolism and as such muscle hypertrophy can take place.
Growth hormonal agent itself does not directly cause muscle hypertrophy but it assists muscle recovery and consequently possibly facilitates the muscle reinforcing procedure. The accumulation of lactate and hydrogen ions (eg in hypoxic training) further increases the release of development hormone.
Myostatin controls and inhibits 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 a build-up of metabolites cell swelling takes place. This swelling within the cells causes an anabolic response and results in muscle hypertrophy.
The cuff is placed proximally to the muscle being workout and low intensity exercises can then be performed. Since the outflow of blood is limited using the cuff capillary blood that has a low oxygen content gathers and there is an increase in protons and lactic acid. The same physiological adjustments to the muscle (eg release of hormones, hypoxia and cell swelling) will occur during the BFR training and low intensity exercise as would happen with high strength workout.
( 1) Low intensity BFR (LI-BFR) leads to an increase in the water material of the muscle cells (cell swelling). It likewise accelerates the recruitment of fast-twitch muscle fibres. It is also assumed that as soon as the cuff is eliminated a hyperemia (excess of blood in the capillary) will form and this will cause additional cell swelling.
These increases resembled gains obtained as a result of high-intensity exercise without BFR A research study comparing (1) high intensity, (2) low strength, (3) high and low intensity 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 intensity (group 1) and BFR (groups 3 and 4) produced the greatest result size and were equivalent to each other.
