Abstract:
1. A belt for muscle training for the development of muscles that is used for applying a predetermined force for pressurization to a target compressed site near the proximal portion of one of the limbs of a user so that blood flow through the limb is restricted, the belt comprising: a band-shaped member having a band shape; and fastening means, wherein said fastening means is comprised of: a first hook-and-loop fastener that is provided on the outer surface of said band-shaped member at a position where said loop is to be formed; a second hook-and-loop fastener that is provided on the inner surface of said band-shaped member over a predetermined range from said one end of said band-shaped member, the second hook-and-loop fastener being adapted to be removably attached to said first hook-and-loop fastener; and a third hook-and-loop fastener that is provided on the inner surface of said band-shaped member over a predetermined range from said other end of said band-shaped member, the third hook-and-loop fastener being adapted to be removably attached to said first hook-and-loop faster, wherein an opening is formed between a one end of said band-shaped member and an other end thereof at a position closer to said other end such that a portion of said band-shaped member having a predetermined length from said one end can be inserted into the opening, wherein the length of said band-shaped member from said one end to said opening is equal to or longer than the length that is enough to be wound around said target compressed site one complete turn, the length of said band-shaped member from said other end to said opening is shorter than the length that is enough to be wound around said target compressed site one complete turn, and the total length of the band-shaped member is slightly shorter than twice the circumference of the target compressed site such that the one end of the band-shaped member is not overlapped with the other end thereof when the first hook-and-loop fastener and the second hook-and-loop fastener are engaged with each other, and the first hook-and-loop fastener and the third hook-and-loop fastener are engaged with each other, wherein a predetermined tension is applied to said band-shaped member by means of pulling said one end of said band-shaped member and said other end thereof in opposite directions, with said target compressed site of the user being placed in a loop made of a part of said band-shaped member extending from said opening to an appropriate position on the side of said one end, the loop being generated by means of passing said one end of said band-shaped member through said opening, and wherein the shape of said band-shaped member to which the predetermined tension is being applied is kept by means of said fastening means.
