Experimental comparison of skier’s motions when using slap ski and conventional ski

Abstract

To improve alpine ski racer's turn skill, Slap-ski which could be heel-freed has been developed. In Previous report, motions of skier's using both of conventional carving ski and Slap ski are measured by using motion capture. As a result, the skier which brought up the potential of Slap-ski, made extended its ROM of hips and knee joints, and in 1st half term, the direction of pelvis heading toward inside of turns, in case of using Slap-ski, compared with the conventional ski's results. However, it was a result in attempts which are unregulated in running tracks. In this report, to clarify the results of previous report and identify the characteristic of Slap-ski in alpine ski racing, the motions of skier during using both of Slap-ski and conventional ski has been measured in course which is regulated in running track. Furthermore, the results of the experiment have been discussed.
