1. A ski training apparatus comprising:

  • a pair of left and right footboards on which a trainee stands instead of skis;

    a movable portion which supports said footboards to allow said footboards to rotate clockwise and counterclockwise, and swings to displace said footboards along an arcuated locus in accordance with ski-sliding movement of the trainee;

    an apparatus body which supports said movable portion to allow said movable portion to swing in a horizontal direction;

    measuring means for measuring loads of the left and right feet of the trainee standing on said footboards, and outputting the measured loads as load information, while measuring a displacement amount of said movable portion and rotational angles of said footboards, and outputting the measured amount and angles as displacement information;

    movement estimating means for estimating a sliding velocity, a position of the trainee on a slope, and an edging strength representing a magnitude of a reactive force received from a snowy surface and corresponding to a load of the trainee on the snowy surface on the basis of the load information and the displacement information, which are supplied from said measuring means, and geographical information input in advance and indicating a state of the inclined surface on which the trainee slides, and outputting the estimated sliding velocity, position, and edging strength as movement information; and

    braking control means for calculating a braking amount by using the load information and the displacement information which are supplied from said measuring means and the movement information which is supplied from said movement estimating means, and outputting the braking amount as braking information; and

    braking means for applying a braking force to said movable portion in accordance with the braking information from said braking control means.
