KAATSUtraining, also known as blood flow restriction training (Bloodflowrestrictiontraining), is a new training method, which was invented in Japan in the 1980s and 1990s. Blood flow restriction can achieve the effect of high-intensity strength training through low-intensity muscle stimulation, ensuring the safe and effective completion of training goals, and it is also widely used in the field of rehabilitation and health care.
Currently, blood flow restriction devices are mainly divided into inflatable and non-inflatable (elastic straps). Inflatable devices are mainly medical sphygmomanometers or electronic pressure devices. It is used more in guidance and laboratories; the elastic straps are mainly nylon straps with scales, which are used by the general fitness crowd. Recently, a patented limb compression training device with simple structure, low production cost, providing compression position and accuracy, simple and convenient operation, portability and safety has been found, which is more suitable for public fitness.
The study found that low-intensity aerobic exercise (walking) combined with blood flow-restricted training methods can significantly increase the level of physical activity in the elderly and sedentary population by 2.5-4.5 times; using blood-flow restriction combined with low-intensity cycling During training, the training intensity was set at 40% VO2max intensity, the pressure of blood flow restriction was gradually increased from 120mmHg to 210mmHg, and the VO2max of subjects in the blood flow restriction group increased significantly. Previous studies have found that blood flow-restricted training combined with low-intensity aerobic endurance can improve physical activity levels in the general population.
Studies have shown that low-intensity KAATSU exercise increases muscle size and strength, as well as increases blood growth hormone. Exercising by properly controlling the blood flow by pressurizing, because of the anaerobic state, the muscles produce the fatigue substance – lactic acid in a short time. A large amount of lactic acid stimulates the anterior pituitary gland of the brain to secrete a large amount of growth hormone, which can not only improve physical fitness, but also promote human metabolism, enhance the elasticity of blood vessel walls, and prevent various diseases caused by metabolic syndrome. In addition, studies have also proved that compression can promote the recovery of surgical diseases such as fractures and sprains, and shorten the recovery time.
At present, the level of physical activity of the general public is declining. With the continuous advancement of the construction of a healthy China, the public’s health awareness has been continuously improved, and the number of fitness groups has continued to increase. In order to reduce the occurrence of sports injuries, improve the training effect and maximize the training purpose, the lower limbs are pressurized through the blood flow restriction device during jogging, which can greatly improve the cardiorespiratory endurance and sports performance of the general population through a smaller exercise intensity. , reduce the risk of diseases such as knee injuries.
