Abstract
A training device includes, a cable that is paid out in response to movement of a user, a reel on which the cable is wound, a rotary encoder to detect a rotation state of the reel, a magneto-rheological fluid brake to apply a braking force to the reel, and a controller configured or programmed to calculate a stroke amount of the cable based on an output value of the rotary encoder and to control the braking force based on the stroke amount to change a magnitude of a load during the movement.
Claims6
A training device, comprising:
- a cable that is paid out in response to movement of a user;
- a measurer to measure a stroke amount of the cable;
- a magneto-rheological fluid brake to apply a braking force to the cable;
- and
- a controller configured or programmed to calculate the stroke amount of the cable based on an output value of the measurer and to control the braking force based on the stroke amount to change a magnitude of a load during the movement;
- wherein
- the measurer includes a reel on which the cable is wound and a rotary encoder to detect a rotation state of the reel;
- and
- the reel, the rotary encoder, and the magneto-rheological fluid brake are provided on a same rotating shaft.
