Patent ID: 8858397

Claim:
A training device doing muscular workout to apply load caused by a rotary torque of an electric motor to an exerciser comprising: a detection means seeking for a velocity or acceleration of an exercise in the muscular workout; a load characteristic input device for inputting a velocity-load characteristic being a load characteristic to the velocity or an acceleration-load characteristic being a load characteristic to the acceleration; a load characteristic memory device memorizing the velocity-load characteristic or the acceleration-load characteristic; and a control means calculating a torque instruction value as a driving current in accordance with the velocity-load characteristic or the acceleration-load characteristic memorized in the load characteristic memory device and controlling a rotary torque of the electric motor in accordance with the torque instruction value, wherein the velocity-load characteristic is a load characteristic passing through a zero point and facing a reverse direction between a positive value and a negative value in velocity in case where the load characteristics are shown as a characteristic line on a coordinate with a velocity and a load designated as each axis, respectively, wherein the velocity-load characteristic changes a slope of the load at forth and return routes to obtain a suitable velocity-load characteristic for each exerciser, and at first the velocity-load characteristic is given such that the velocity-load characteristic passes through a point that denotes an ideal load at a standard velocity, which is ideal moving velocity for the exerciser, and wherein when an exercise velocity, at which the exerciser used to exercise, less than the standard velocity, the control means changes the velocity-load characteristic so that the velocity-load characteristic passes through a point that denotes an exercise load, which is equal to a load at the exercise velocity on the velocity-load characteristic before changing, at the standard velocity, or passes through a point that denotes a predetermined load at the standard velocity wherein the product of the standard velocity and the predetermined load is equal to the product of the exercise velocity and the exercise load.
