Outline of Final Research Achievements

The purposes of this study were to develop the mechanism to generate a torque around the center of gravity in ski turning automatically and develop the prototype of new concept chair ski equipping this mechanism. The procedures of this study were 1) reconsideration of ski turning for concept design and proposal of the new chair ski. 2) verification of an effectiveness of the proposed concept. 3) production of the new concept chair ski prototype. This study’s results were summarized as follows; 1) the motion generating a torque around the center of gravity in an expert skier turning was reconfirmed. 2) it was confirmed that the mechanism generating a torque around the center of gravity generated a large torque necessary for ski turning with less muscular strength. 3) the prototype of chair ski equipping the mechanism for generating a torque around the center of gravity in ski turning automatically was developed, and it was confirmed that the new concept chair ski could turn easily.
