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Pedar 足底压力鞋垫（Pedar-X; Novel, Inc.,德国）采集受试者的足底压强峰值及压强分布数据，足底压力鞋垫的采样频率为100Hz。受试者按照以上要求分别测试3次，确保采集数据有效。

During the experiment, the subjects wore speed skates on both feet at the same time, and stood on the plantar pressure plate with natural balance. In order to prevent the sharp skates from damaging the plantar pressure plate, the subjects placed a layer of 2mm EVA cushion between the skates on the left and right sides and the plantar pressure test plate when standing. Pedar plantar pressure insole (Pedar-X; Novell, Inc., Germany) was used to collect the plantar pressure peak and pressure distribution data of subjects. The sampling frequency of plantar pressure insole was 100Hz. The subjects were tested three times according to the above requirements to ensure the validity of the collected data.
