Claim:
1. A training apparatus comprising: a tight fitting band including a belt having a length that is enough to be wrapped around a predetermined region of muscles of a limb; fastening means for fastening said belt with said belt being wrapped around said predetermined region of muscles; and an inflatable bag provided in or on said belt, said inflatable bag being adapted to apply a predetermined compression pressure to said predetermined region of muscles by means of filling said inflatable bag with a gas to fully compress the veins and not fully compress the arteries of said predetermined region of muscles while said belt that has been wrapped around said predetermined region of muscles is fastened by said fastening means; pressure setting means that is capable of setting a gas pressure within said inflatable bag at a predetermined pressure; control means for controlling said pressure setting means in order to change said compression pressure; and pulse wave measuring means for measuring a predetermined parameter at a position near said predetermined region of muscles or a position closer to the distal end of the limb than said predetermined region of muscles, to generate a pulse wave data about the parameter, the parameter fluctuating along with the fluctuation of the magnitude of an arterial pulse wave that is changed in response to said compression pressure, said control means being adapted to direct said pressure setting means to perform preprocessing and normal processing, said control means being also adapted to, upon said preprocessing, control said pressure setting means so that said pressure setting means changes the gas pressure within said inflatable bag; determine a pulse wave component at a time point at which the maximum pulse wave pressure is produced after receiving a plurality of said pulse wave data from said pulse wave measuring means during the time period when the pressure within said inflatable bag is changing; and determine a first reference pressure which is the pressure within the inflatable bag at a time point when such a pulse wave component is produced that has an amplitude obtained by means of multiplying the amplitude of the pulse wave component at the time point at which said maximum pulse wave pressure is produced with a predetermined first coefficient that is equal to or larger than 0.2 but smaller than 1, the first reference pressure being larger than the pressure within said inflatable bag at the time point at which said maximum pulse wave pressure is produced, said control means being adapted to, upon said normal processing, control said pressure setting means so that said pressure setting means keeps the gas pressure within said inflatable bag in a predetermined range above or below said the first reference pressure, wherein said tight fitting band includes a plurality of tight fitting bands, said pulse wave measuring means being equal in number to said tight fitting bands, said pressure setting means being associated with respective one of said tight fitting bands, said pulse wave measuring means being adapted to measure said parameter that fluctuates along with the fluctuation of the magnitude of the pulse wave at a position near a predetermined region of muscles or a position closer to the distal end of the limb than the predetermined region of muscles around which the respective tight fitting bands are wrapped that are associated with the pulse wave measuring means, to generate a pulse wave data about the parameter, said pressure setting means being equal in number to said tight fitting bands, said pressure setting means being associated with respective one of said tight fitting bands, said control means being adapted to control, upon said preprocessing, said pressure setting means to determine the pulse wave component at the time point at which said maximum pulse wave pressure is produced and said first reference pressure for each of the limbs, said control means being adapted to control, upon said normal processing, each of said pressure setting means that are associated with said tight fitting bands, respectively, for compressing the respective limbs, in such a manner that the gas pressure within said inflatable bag of the tight fitting band associated with the pressure setting means falls within a predetermined range above or below said first reference pressure that is determined for the limb for which the associated tight fitting band is to be used.
