The purpose of this study is to establish the system to measure physical form in snowboarding turn, the correction method to improve accuracy and the analysis method to indicate physical form. This system consists of 3D gyro sensor, 3-axis acceleration sensor and 3-axis magnetic sensor. Initial physical form is obtained from 3-axis acceleration sensor and 3-axis magnetic field sensor, gliding physical form is obtained form 3D gyro sensor. The correction method reduces the drift error of gyro sensor using Extended Kalman Filter, the analysis method provides joint angle from information of this measurement system. As a result of experiment on the carving turn by the snowboarder in a skiing ground, the physical form was obtained quantitatively. This measurement system and correction method can analyze the major features of snowboarding turn and this method may be able to quantitatively evaluate the skill of snowboarders.
