地面反作用力和中心的压力（C的P）模式进行了研究，在17个科目运行在4.5 ms-1。根据第一次接触地面时的P线位置，将受试者分为后足或中足罢工者。后足组的P路径的C在支撑过程中表现出连续的向前运动，而中足组的P路径的C在支撑阶段的前20 ms向后迁移。两组的变异性在早期支持期间最为显著。垂直、前后和内外方向的平均峰间力分量分别为3 BW、1 BW和0.3 BW。在所有三个组成部分中注意到组间的一致差异，但给定组内的个体差异也相当大。结合地面反作用力数据，提出了C的P模式，并讨论了在跑步力学，鞋设计和运动损伤领域的结果的影响。
Ground reaction forces and center of pressure (C of P) patterns were studied in 17 subjects running at 4.5 ms-1. The subjects were classified as rearfoot or midfoot strikers according to the location of the C of P at the time of 1st contact between foot and ground. The C of P path in the rearfoot group showed a continuous anterior movement during support while the C of P in most of the midfoot group migrated posteriorly during the first 20 ms of the support phase. Variability in both groups was most marked during early support. The mean peak to peak force components were 3 BW, 1 BW and 0.3 BW in the vertical, anteroposterior and mediolateral directions, respectively. Consistent differences between groups were noted in all three components, but individual differences within a given group were also considerable. The C of P patterns are presented in conjunction with ground reaction force data, and the implications of the results in the areas of running mechanics, shoe design and sports injury are discussed.
