Outline of Final Research Achievements

In order to elucidate the mechanism of snowboard jump, we developed a motion measurement system equipped with inertial and magnetic field sensors and a measurement system of reaction force from snow surface installing the 6-axis force sensors. The mechanism of Ollie motion, the applied force, and posture of snowboarder in snowboard jump are clarified by the motion measurement and kinetics analysis of snowboarder using these measurement systems.
By estimating the posture of the head during jumping through measurement experiments with snowboarders of different skills, an efficient practice method for safe jumping can be expected. Furthermore, an important knowledge for developing a simulation model of snowboard jump was obtained.
