アルペンスキー選手のターン動作における数値的評価

抄録

The Center for Winter Sports Science at the Kitami Institute of Technology has a "SkyTech" ski simulator. In the experiment, the pressure sensor "Pedar" installed on the sole of the ski boot and the "internal inclination angle measurement device" attached to "SkyTech" were used to measure the plantar pressure and internal inclination angle during the turning motion. In this study, we first conducted a questionnaire survey on the players' perceived strengths and weaknesses of left-right turns. Then, we calculated various parameters to numerically evaluate left-right turn movements from the data obtained from the plantar pressure sensor and the internal inclination angle measurement device in an experiment using the "SkyTech" ski simulator, and examined the indexes of the obtained parameters and the players' turn awareness. The results of the experiment tended to be close to the results of the questionnaire. We believe that a clear trend will become apparent when the number of subjects and experiments are increased in the future.
