Individualized blood circulation limitation rehabilitation training (PBFR) is a game-changing injury recovery treatment that is producing considerably positive results: Diminish atrophy and loss of strength from disuse and non-weight bearing after injuries Boost strength with only 30% loads Boost hypertrophy with only 30% loads Enhance muscle endurance in 1/3 the time Enhance muscle protein synthesis in the senior Improve strength and hypertrophy after surgery Improve muscle activation Increase growth hormonal agent actions.
Muscle weak point typically occurs in a variety of conditions and pathologies. High load resistance training has actually been revealed to be the most successful ways in improving muscular strength and acquiring muscle hypertrophy. The problem that exists is that in specific populations that need muscle enhancing eg Chronic Discomfort Patients or post-operative clients, high load and high intensity exercises may not be scientifically suitable.
It has been used in the fitness center setting for some time but it is getting popularity in clinical settings. BFR training was at first developed 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 pumped up to a particular pressure with the goal of obtaining partial arterial and total venous occlusion. Muscle hypertrophy is the boost in diameter of the muscle as well as an increase of the protein content within the fibers.
Muscle stress and metabolic stress are the 2 main elements responsible for muscle hypertrophy. Mechanical Stress & Metabolic Tension [edit edit source] When a muscle is placed under mechanical tension, the concentration of anabolic hormonal agent levels increase. The activation of myogenic stem cells and the elevated anabolic hormones lead to protein metabolism and as such muscle hypertrophy can occur.
Growth hormonal agent itself does not directly trigger muscle hypertrophy however it assists muscle recovery and thus possibly facilitates the muscle strengthening procedure. The build-up of lactate and hydrogen ions (eg in hypoxic training) more increases the release of development hormonal agent.
Myostatin controls and prevents cell growth in muscle tissue. It needs to be basically shut down for muscle hypertrophy to occur. Resistance training results in the compression of capillary within the muscles being trained. This causes an hypoxic environment due to a decrease in oxygen delivery to the muscle.
This causes an increase in anaerobic lactic metabolism and the production of lactate. 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 leads to muscle hypertrophy. The cell swelling may really trigger mechanical stress which will then activate the myogenic stem cells as talked about above.
The cuff is placed proximally to the muscle being workout and low intensity exercises can then be carried out. Since the outflow of blood is limited utilizing the cuff capillary blood that has a low oxygen material collects and there is a boost in protons and lactic acid. The very same physiological adaptations to the muscle (eg release of hormones, hypoxia and cell swelling) will happen throughout the BFR training and low strength exercise as would occur with high intensity exercise.
( 1) Low strength 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 when the cuff is gotten rid of a hyperemia (excess of blood in the capillary) will form and this will cause more cell swelling.
These boosts were comparable to gains gotten as a result of high-intensity workout without BFR A study comparing (1) high strength, (2) low strength, (3) low and high intensity with BFR and (4) low strength 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 best effect size and were similar to each other.
