Effects Of Resting Vs. Continuous Blood-flow ... - Frontiers

1. Personalized blood circulation restriction rehab training (PBFR) is a game-changing injury recovery treatment that is producing dramatically positive results: Decrease 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 senior Improve strength and hypertrophy after surgery Improve muscle activation Increase growth hormone reactions. Muscle weak point frequently occurs in a variety of conditions and pathologies. High load resistance training has been shown to be the most effective methods in enhancing muscular strength and acquiring muscle hypertrophy. The problem that exists is that in specific populations that require muscle reinforcing eg Persistent Pain Patients or post-operative patients, high load and high intensity exercises might not be scientifically suitable. It has been used in the gym setting for some time however it is getting popularity in medical settings. 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 getting partial arterial and complete venous occlusion. Muscle hypertrophy is the increase in size of the muscle as well as an increase of the protein content within the fibres. Muscle tension and metabolic tension are the two main elements responsible for muscle hypertrophy. Mechanical Stress & Metabolic Tension [edit edit source] When a muscle is positioned under mechanical stress, the concentration of anabolic hormone levels increase. The activation of myogenic stem cells and the raised anabolic hormones result in protein metabolic process and as such muscle hypertrophy can occur. Insulin-like development element and development hormone are accountable for increased collagen synthesis after workout and aids muscle healing. Growth hormonal agent itself does not directly trigger muscle hypertrophy but it helps muscle healing and thus potentially facilitates the muscle reinforcing process. The accumulation of lactate and hydrogen ions (eg in hypoxic training) further boosts the release of growth hormone. Myostatin controls and inhibits cell growth in muscle tissue. It requires to be basically closed down for muscle hypertrophy to occur. Resistance training leads to the compression of capillary within the muscles being trained. This triggers an hypoxic environment due to a reduction in oxygen shipment to the muscle. When there is blood pooling and a build-up of metabolites cell swelling takes place. This swelling within the cells triggers an anabolic reaction and results in muscle hypertrophy. The cuff is placed proximally to the muscle being workout and low intensity exercises can then be carried out.

2. Because the outflow of blood is restricted utilizing the cuff capillary blood that has a low oxygen content gathers and there is an increase in protons and lactic acid. The exact same physiological adjustments to the muscle (eg release of hormones, hypoxia and cell swelling) will take location throughout the BFR training and low strength exercise as would occur with high intensity workout. ( 1) Low strength BFR (LI-BFR) results in a boost in the water content of the muscle cells (cell swelling). It also accelerates the recruitment of fast-twitch muscle fibers. It is likewise hypothesized that when the cuff is gotten rid of a hyperemia (excess of blood in the blood vessels) will form and this will trigger more cell swelling. These increases were comparable to gains obtained as an outcome 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 exercise regimes produced boosts 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 best effect size and were comparable to each other.
