Personalized blood flow limitation rehabilitation training (PBFR) is a game-changing injury recovery treatment that is producing dramatically positive outcomes: Decrease 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 Improve muscle endurance in 1/3 the time Improve muscle protein synthesis in the elderly Improve strength and hypertrophy after surgery Improve muscle activation Increase growth hormonal agent reactions.

Muscle weakness frequently happens in a range of conditions and pathologies. High load resistance training has been revealed to be the most successful means in enhancing muscular strength and acquiring muscle hypertrophy. The problem that exists is that in certain populations that require muscle enhancing eg Chronic Discomfort Patients or post-operative patients, high load and high strength workouts may not be medically appropriate.

It has been utilized in the fitness center setting for some time however it is gaining popularity in clinical settings. BFR training was initially developed in the 1960's in Japan and understood as KAATSU training.

It can be used to either the upper or lower limb. The cuff is then inflated to a particular pressure with the goal of acquiring partial arterial and total venous occlusion. The patient is then asked to perform resistance exercises at a low intensity of 20-30% of 1 repeating max (1RM), with high repeatings per set (15-30) and brief rest intervals in between sets (30 seconds) Understanding the Physiology of Muscle Hypertrophy. [modify edit source] 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 two main factors responsible for muscle hypertrophy. Mechanical Stress & Metabolic Tension [edit modify source] When a muscle is put under mechanical stress, the concentration of anabolic hormone levels increase. The activation of myogenic stem cells and the elevated anabolic hormonal agents lead to protein metabolism and as such muscle hypertrophy can happen.

Insulin-like development aspect and growth hormonal agent are accountable for increased collagen synthesis after exercise and aids muscle healing. Growth hormonal agent itself does not straight trigger muscle hypertrophy however it aids muscle healing and consequently potentially facilitates the muscle strengthening process. The build-up of lactate and hydrogen ions (eg in hypoxic training) additional increases the release of growth hormone.

Myostatin controls and hinders cell growth in muscle tissue. Resistance training results in the compression of blood vessels within the muscles being trained.

This results in an increase 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 response and leads to muscle hypertrophy. The cell swelling might really trigger mechanical tension which will then activate the myogenic stem cells as discussed above.

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

( 1) Low intensity BFR (LI-BFR) leads to a boost in the water content of the muscle cells (cell swelling). It likewise accelerates the recruitment of fast-twitch muscle fibres. It is likewise assumed that as soon as 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 similar to gains gotten as an outcome of high-intensity exercise without BFR A research study comparing (1) high strength, (2) low intensity, (3) high and low strength with BFR and (4) low strength with BFR. While all 4 exercise programs 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 biggest result size and were comparable to each other.
