Abstract

    Skeleton is a winter sport in which competitors aim to drive a one-person sled in a prone, head-first position down an ice track in the fastest time. Top speeds attained in skeleton are approximately 130 km/h. But studies of skeleton have not been carried out until now. The purposes of this study were to measure the dynamic strain, the vertical acceleration and the horizontal acceleration applied to the sled frame, and try to construct a feedback system for athletes.
    The experiments were carried out at the Spiral. In the experiment, first a strain gage and an acceleration transducer were attached to the frame, then data was collected with a compact recorder.
    The results are summarized as follows.
·Measuring acceleration and strain for result, it is possible to give the athletes feedback on data.
·Vertical acceleration was 2-4G, greater than horizontal acceleration. Horizontal acceleration was 1-2G at curve.
