Claim:
1. An exercise therapy device, which is configured to use isokinetic load control and constant-watt load control in combination when an exerciser operates right and left pedals to carry out training, the isokinetic load control controlling a load torque to be applied to each of the right and left pedals so that the load torque becomes equal to a rotation torque applied to each of the right and left pedals by pedaling of the exerciser, the constant-watt load control controlling a target torque value to be applied to each of the right and left pedals so that one of an average watt, which is an average value of a power in one rotation of the pedaling of the exerciser, and a peak watt, which is a maximum value of the power, becomes constant among rotations of the pedaling, the exercise therapy device comprising: a man-machine interface unit, used by the exerciser, configured for selecting and setting a target exercise load value; a load control unit configured for controlling an exercise load to be applied to the exerciser according to the target exercise load value; one load motor controlled by the load control unit to generate the exercise load; a speed reduction mechanism configured for transmitting the exercise load generated by the one load motor to legs of the exerciser as a load torque and rotation speed; and the right pedal and the left pedal are coupled to the speed reduction mechanism so as to be freely rotatable when used by the exerciser, wherein the load control unit comprises: wherein the exercise therapy device controls the exercise load by using the isokinetic load control and the constant-watt load control in combination by the use of only the one load motor.
