ABSTRACT:
A movement training device includes a crank including crankarms and pedals disposed on the crankarms, the pedals being connectable to feet or arms of a person training; an electric motor transmission-connected to the crank for driving and braking the crank in both directions of rotation; a four-quadrant power electronics device operatively connected to the motor for supplying current thereto to drive and brake the crank; and a computer for detecting an angular position, a speed of rotation and a torque of the crank including respective directions thereof as instantaneous actual characteristic quantities of a crank movement and for placing the instantaneous actual characteristic quantities in a digital and thereby freely utilizable form. The computer includes a regulating and control arrangement which can utilize digital values of the instantaneous actual characteristic quantities of the crank movement and other, externally recorded characteristic quantities for regulating and controlling the crank movement and for transmission to peripheral devices. The regulating and control arrangement includes: a speed regulating arrangement for regulating the speed of the crank; a torque limiting arrangement for limiting a torque of the crank; and a program control arrangement for stipulating and running a temporal training program.
