Summary:The development of ski goods like a carving ski is increasingly remarkable these days. In this study, we propose the new technique to evaluate the performance of ski goods using biomechanical method. In order to analyze the kinetics of skiing, the motion of a skier's body in the skiing turn has been measured by magnetic position sensors. Reaction forces from the snow surface to the skier have been measured using 6 axis force sensors embedded in the bottom of ski boots. Joint moments of a skier have been calculated from these measured data. Then, we have estimated the energy consumption of the muscles based on the muscle-skeletal model. The experimental results show that characteristics of the ski turn can be evaluated through the activity of the muscles. Our evaluation method will be useful not only for developing ski goods for bio-analysis in sports.
