J1020103 内傾角速度を向上するスキーブーツ用フットベッドの設計

抄録

This study investigates a design of a new foot bed for ski boots which can improves the angular velocities of lean motion of skier to decrease the time of alpine ski races for all of the alpine skiers. The subject is the five top level alpine-skier in Japan, and the experimets are carried out by using a ski simulator "Skytec". The foot pressure distribution and the angular velocity during lean motion are measured by using the "Pedar"(foot pressure distribution sensor) and a gyro sensor. Also this study measures the downhill time in the field test. The experimental results revealed that the movement of the center of plantar pressure distribution in the horizontal direction and the position of the foot pressure at the begining of turn affect to the angular velocity of lean motion. In addition, this study show that competition results are improved effectively by attaching the proposed parts to the front of the foot bed bottom.
