受试者为足模型提供者，实验过程中受试者双脚同时穿着速滑鞋，自然平衡站立于足底压力平板上，为预防锋利的冰刀对足底压力平板造成损坏，受试者站立时在左右两侧的冰刀与足底压力测试平板之间均垫一层2mm的EVA软垫。使用Novel emed-X足底压力测试平板（Novel，德国）采集刀底压强峰值及压强分布数据，压力测试平板的采样频率均为100Hz。受试者按照以上要求分别测试3次，确保采集数据有效。

The subject is a foot model provider. During the experiment, the subject wears speed skates on both feet at the same time and stands on the plantar pressure plate with natural balance. In order to prevent the sharp skates from damaging the plantar pressure plate, the subject places a layer of 2mm EVA cushion between the skates on the left and right sides and the plantar pressure test plate when standing. Use the Novell emed-X plantar pressure test plate (Novell, Germany) to collect the peak pressure and pressure distribution data at the bottom of the knife. The sampling frequency of the pressure test plate is 100Hz. The subjects were tested three times according to the above requirements to ensure the validity of the collected data.
