Expectations for preventive medicine are increasing as national medical expenses increase. While preventive medicine covers a wide range of fields, the prevention and improvement of motor system-related diseases and conditions such as “locomotive syndrome,” “sarcopenia” and “frailty” by stimulating physical exercise in patients is an important issue. Recent years have seen many reports of increased muscle strength and muscle hypertrophy by subjecting the body to stimuli such as pressurization, electrical stimulation, or vibration, even with short-duration low-intensity training, a method that has so far been said to have little effect in terms of physical enhancement. Among these, “Kaatsu training” is well known as a method that has been said to improve muscle function and morphology through short-duration low-intensity muscle training with the blood flow restricted (BDR: Blood Flow Restriction) by a pressurizing belt fastened around articulations in the body, particularly the joints between the limbs and trunk of the body (armpit and groin regions). This study reports on knowledge acquired through verification of the results of vigorous exercise performed three times with the test subject stimulated by RIC (Regional and Remote Ischemic Conditioning) using a new device, a method based on BFR used in Kaatsu training.
