Abstract: A muscle training method includes the following steps that are repeated alternately to perform training of a muscle of a user: a pressuring and exercise step (S30, S50, S70, S90) of winding a belt around at least one of four limbs of the user and applying specific pressure thereto so as to restrict blood circulation of the muscle of the user without stopping the blood circulation, and asking the user to perform load-applied exercise to apply load of specific weight to the muscle of the user; and an exercise stopping step (S40, S60, S80, S100) of asking the user to stop the load-applied exercise while continuously applying the specific pressure to the user. The specific weight is set at a value smaller than maximum weight necessary for the user to exert maximum muscle force.

Abstract: Provided are a method for strengthening blood vessels with extreme ease and a compression and decompression control system used for performing the method. A compression and decompression control system 1 includes a band adapted to be placed around a particular part of a limb of a user and to apply a compression force to the particular part and a controller for controlling the compression force applied to the particular part with the band. The controller controls the compression force applied with the band in a manner that a compression operation applying a predetermined compression force to the particular part and a decompression operation completely removing the compression force applied to the particular part by the compression operation are alternately repeated. Repetition of the compression operation and the decompression operation allows the vascular endothelial cells of blood vessels of the user to generate a larger amount of nitric oxide, thereby strengthening the blood vessels.

Abstract: To ensure easy and secure placement of a belt for KAATSU muscle training on a target compressed site near the proximal portion of a limb. A belt 100B has a longer first band-shaped member 110 and a shorter second band-shaped member 120 both of which have a band shape and are connected to a ring-shaped joint member 130 at their respective ends. In order to place the belt 100B on the target compressed site, the limb (right leg in this case) on which the belt 100B is expected to be placed is inserted into a loop of the first band-shaped member 110 formed by passing the end of the first band-shaped member 110 through an opening in the joint member 130, and the belt is moved up to the target compressed site. Then, the first band-shaped member 110 and the second band-shaped member 120 are pulled with both hands in the opposite directions. The belt 100B is placed on the target compressed site with the belt 100B being tensioned appropriately.
