Development of a Measuring System for Joint Angles of a Skier and Applied Forces during Skiing

To investigate the relationship between the joint angles of a skier and the forces acting on the skis from the snow surface in a turn, a new compact measuring system has been developed. It consists of a goniometer on the hip and knee joints, a force sensor placed between a ski and its binding, and a notebook computer as a data recorder. Using this system, measurements are carried out during a long parallel turn. The results obtained from the experiments are summarized for one cycle of a turn. They are very useful for the development of ski equipment and to clarify the dynamic mechanism of turn on skis.
