携帯型高精度キネマティックGNSSを用いたクロスカントリースキーの運動解析

抄録

Since kinematic Global Navigation Satellite System (GNSS) has highly accurate positioning ability, it has been used for sports kinesiology such as 3D movement measurement and analysis. Unlike camcorders, GNSS loggers must be attached to measuring subjects, most of which are bodies of athletes and their tools. Therefore we have developed a compact and lightweight GNSS logger named AT-H-02 with post-processed kinematic mode. The purpose of this report is to analyze the motion of a high-level cross country skier. By using the AT-H-02, we measured positioning data of Mr. Petter Eliassen who won the 1st prize at Reistadlopet 50km cross country ski race held in northern Norway at 3rd April 2017. From the motion analysis, we obtained many interesting implication such as slope angle vs. velocity relation.
