Motion analysis of skier using slap ski

Abstract

To improve alpine ski racer's turn skill, it is important to make turns smaller in radius of curvature. For realizing this issue, slap ski which could be heel-freed has been developed. In this study, the motions of expert and beginner skiers have been measured by using wearable motion capture system during skiing with slap ski or conventional ski. In case of using slap ski, the slap plate angle has also been measured to confirm the heel-freed level during turns. Furthermore, the results of the experiment have been discussed.
