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.
