Training apparatus, training method, storage medium, and training system

Abstract

A training apparatus includes a display that displays a video image including an image of a moving object, a rotation speed acquirer that acquires a rotation speed of a pedal driven by a user, and a control circuit that changes a moving speed of the object in the video image. The control circuit controls the moving speed as follows. The moving speed of the object in the video image is increased at an acceleration α1 (>0). If an increase in the pedal rotation speed occurs after the moving speed of the object is increased, the moving speed of the object is increased at an acceleration α2 (<α1). In a case where an increase in the rotation speed of the pedal occurs after the moving speed of the object is increased at the acceleration α2, the moving speed of the object is further continuously increased at the acceleration α2.
