Outline of Final Research Achievements

We examined the image and measurement of insole pressure load and the center of pressure (COP) at the open gate of the slalom event. We had an image of a strong external leg load in the maximum load phase of the ski turn in the Alpine Olympic athletes. The external leg load (insole pressure) was 75 to 70% and the inner leg was distributed to 25% to 30%. The COP was seen to move forward in the switching period of the turn phase, and the image and the measurement were similar, but there was a point which did not agree. The body seems to move faster than the image because a fast operation is demanded in the slalom competition. Depending on the snow condition and speed, the athlete might be trying to maintain a stable posture based on these perceived foot pressure information in consciousness and unconsciousness.
