Blood Flow Restriction (BFR) is an emerging training method originally created by Dr. Yoshiaki Sato from Japan. It is also called KAATSU and is used to improve muscle mass and strength performance.
BFR works by restricting part of the inflow of arterial blood flow and completely restricting the return of venous blood from the muscle tissue to the heart during exercise, rather than completely blocking the blood flow in the arteries and veins; it applies pressure by using a pressure cuff on the proximal upper or lower limbs. , BFR can be combined with various types of exercise, and has obvious effects in rehabilitation exercises, enhancing muscle strength (Muscle Strength) and muscle hypertrophy (Muscle Hypertrophy). It is suitable for athletes, generally healthy people and senior people; It is also widely used in medicine to treat patients with various diseases. BFR will cause metabolites to accumulate lactate (lactate), inorganic phosphate (Pi) and hydrogen ions (H^+) in muscle cells. These metabolites will affect hormone release, hypoxia, reactive oxygen species (ROS) and cell swelling. and initiates anabolic signaling to promote muscle growth, muscle hypertrophy, and energy metabolic adaptations. In terms of application, it can be combined with resistance exercise (RE) and aerobic exercise (AE).
In recent years, there has been more novel research on combining it with neuromuscular stimulation, such as electrical stimulation (Electrical Stimulation), whole body Use Whole Body Vibration to combine. Regarding the exercise prescription for the application of BFR in resistance training, the most recommended currently is to implement 4 sets (30 times, 15 times, 15 times, 15 times respectively) for a total of 75 repetitions, with a 60-second rest period between sets to continue blocking blood flow. , and training at 20%-40% of personal maximum muscle strength (1RM) can best improve muscle strength and muscle hypertrophy. This training mode is suitable for most ethnic groups.
Blood flow occlusion combined with low-intensity exercise can produce training effects similar to high-intensity exercise, so clients do not need to engage in high-intensity exercise to achieve the desired therapeutic effect. Our therapists will develop a customized exercise therapy plan for our clients.
