Individualized blood flow limitation rehab training (PBFR) is a game-changing injury healing therapy that is producing drastically positive results: Reduce 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 Improve muscle protein synthesis in the elderly Improve strength and hypertrophy after surgical treatment Enhance muscle activation Boost growth hormone actions.
Muscle weakness frequently happens in a range of conditions and pathologies. High load resistance training has actually been shown to be the most effective means in improving muscular strength and acquiring muscle hypertrophy. The issue that exists is that in certain populations that require muscle reinforcing eg Persistent Pain Patients or post-operative patients, high load and high intensity exercises may not be medically suitable.
Blood Circulation Limitation (BFR) training is a strategy that combines low strength workout with blood flow occlusion that produces similar outcomes to high strength training. It has actually been used in the fitness center setting for some time but it is acquiring popularity in clinical settings. Blood Flow Limitation (BFR) Training [edit edit source] BFR training was initially 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 objective of acquiring partial arterial and total venous occlusion. Muscle hypertrophy is the increase in size of the muscle as well as a boost of the protein content within the fibers.
Muscle stress and metabolic stress are the two main aspects accountable for muscle hypertrophy. Mechanical Tension & Metabolic Tension [edit edit source] When a muscle is positioned under mechanical stress, the concentration of anabolic hormonal agent levels increase. The activation of myogenic stem cells and the elevated anabolic hormonal agents result in protein metabolism and as such muscle hypertrophy can happen.
Growth hormonal agent itself does not directly trigger muscle hypertrophy however it assists muscle healing and therefore potentially helps with the muscle enhancing process. The accumulation of lactate and hydrogen ions (eg in hypoxic training) more boosts the release of development hormone.
Myostatin controls and prevents cell growth in muscle tissue. It needs to be essentially closed down for muscle hypertrophy to occur. Resistance training leads to the compression of blood vessels within the muscles being trained. This triggers an hypoxic environment due to a decrease in oxygen delivery to the muscle.
This results in a boost in anaerobic lactic metabolism and the production of lactate. When there is blood pooling and a build-up of metabolites cell swelling occurs. This swelling within the cells causes an anabolic response and leads to muscle hypertrophy. The cell swelling might in fact cause 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 workouts can then be carried out. Because the outflow of blood is restricted using the cuff capillary blood that has a low oxygen material gathers and there is a boost in protons and lactic acid. The exact same physiological adaptations to the muscle (eg release of hormonal agents, hypoxia and cell swelling) will occur during the BFR training and low intensity exercise as would accompany high intensity workout.
( 1) Low intensity BFR (LI-BFR) leads to an increase in the water material of the muscle cells (cell swelling). It likewise speeds up the recruitment of fast-twitch muscle fibres. It is also hypothesized that when the cuff is gotten rid of a hyperemia (excess of blood in the blood vessels) will form and this will cause additional cell swelling.
These increases were comparable to gains acquired as a result of high-intensity exercise without BFR A research study comparing (1) high intensity, (2) low intensity, (3) low and high intensity with BFR and (4) low intensity with BFR. While all 4 workout programs produced increases 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 biggest effect size and were similar to each other.
