ROTATION ANGLE MEASUREMENT DEVICE, ROTATION ANGLE MEASUREMENT METHOD, PIVOT FOOT MEASUREMENT METHOD, TRAINING DEVICE, AND TRAINING METHOD

摘要

Provided are: a rotation angle measurement device capable of increasing the flexibility of a human body; a rotation angle measurement method; a pivot foot measurement method capable of determining a pivot foot; a training device for strengthening the muscle force (or muscle) of each part of the human body; and a training method.The present invention is provided with: an upper rotation member (12) rotating about the axis of a center shaft with a human body in contact with the upper rotation member; a lower support member (14) for supporting the upper rotation member (12) so that the upper rotation member (12) can rotate about the axis of the center shaft (22); a rotation angle scale member (30) provided with a rotation angle scale (32) for indicating the rotation angle of the upper rotation member (12); and a rotation angle pointer member (28) rotating together with the rotation of the upper rotation member (12) about the axis of the center shaft (22) and pointing to a predetermined position on the rotation angle scale (32).
