We study the dynamics of sequential turning motions of snowboarder. We assume that the snowboarder is described by a stick-picture figure and only his ankle joints can be bended or extended. The snowboarder rides on a snowboard by normal stance, namely the front of his body always faces to the right-hand side of the snowboard. Assuming a frictional resistant force between the side edge of snowboard and snow surface, we deduce a set of simultaneous equations of motion for this snowboarder riding on the snowboard. We solved these equations of motion numerically under realistic conditions of repeated turns on a flat slope by snowboarding. We found the successful timing of bending as well as extending the ankle joints during repeated turns. The results are shown as animation on computer display.
