Abstract

This paper deals with the motion analysis of snowboard turns using the measurement information of gliding on the actual snow field. The motion measurement systems that measure 3-axis angular velocity, 3-axis acceleration and 3-axis magnetic field are attached to the body segments of snowboarder and the bindings. The 3D posture is estimated by applying the sensor fusion using Extended Kalman filter. The joint torque of snowboarder is estimated by applying the measurement information of the systems to the closed-loop inverse dynamics. We conducted the measurement experiment by the snowboarder gliding on the actual snow field. The results represented the optimal joint torque of snowboarder in the snowboard turns. Furthermore, the analysis was conducted using the joint torque estimated by the proposed and previous methods. The results indicated the major and additional joint torque. Therefore, the analysis method can be used to the clarification of turn mechanism and the skill rating.
