This paper deals with the motion analysis of carving turns in snowboarding by the measurement of reaction force from surface. The measurement system of reaction force from snow surface is installed to between the snowboard and bindings, and the system can measure the 6-axis force components from snow surface (force and moment) using the outputs of several 3-axis compact force sensors. We conducted the measurement experiment of carving turns by a high skill snowboarder. The results denoted the reaction force from snow surface vary from sec to sec. Furthermore, we compared the results of high skill and low skill snowboarders. The results denoted the difference of reaction forces by the difference of snowboarder's skill. The results can be used to clarify the mechanism of snowboard turns and to evaluate the snowboarder's skill.
