BACKGROUND
We aimed to determine the center of pressure (COP) trajectories and regional pressure differences in natural rearfoot strikers while running barefoot, running with a minimalist shoe, and running with a traditional shoe.
METHODS
Twenty-two male natural rearfoot strikers ran at an imposed speed along an instrumented runway in three conditions: barefoot, with a traditional shoe, and with a minimalist shoe. Metrics associated to the COP and regional plantar force distribution, captured with a pressure platform, were compared using one-way repeated-measures analysis of variance.
RESULTS
The forefoot contact phase was found to be significantly shorter in the barefoot running trials compared with the shod conditions (P = .003). The initial contact of the COP was located more anteriorly in the barefoot running trials. The mediolateral position of the COP at initial contact was found to be significantly different in the three conditions, whereas the final mediolateral position of the COP during the forefoot contact phase was found to be more lateral in the barefoot condition compared with both shod conditions (P = .0001). The metrics associated with the regional plantar force distribution supported the clinical reasoning with respect to the COP findings.
CONCLUSIONS
The minimalist shoe seems to provide a compromise between barefoot running and running with a traditional shoe.
背景
本研究旨在确定自然足跟先着地跑者在赤脚、穿极简鞋和穿传统鞋三种状态下的压力中心（COP）轨迹和局部压力差异。
方法
22 名男性自然足跟先着地跑者在三种条件下（赤脚、穿传统鞋和穿极简鞋）以规定速度在带有测力板的跑道上跑步。使用单向重复测量方差分析比较与 COP 和局部足底压力分布相关的指标，这些指标是通过压力平台捕捉到的。
结果
与穿鞋状态相比，赤脚跑步时前脚触地阶段明显缩短（P=0.003）。COP 的初始接触点更靠前。COP 在初始接触时的内外侧位置在三种状态下存在显著差异，而在前脚触地阶段，COP 的最终内外侧位置在赤脚状态下比穿鞋状态更偏外侧（P=0.0001）。与 COP 发现相关的局部足底压力分布指标支持临床推理。
结论
极简鞋似乎在赤脚跑步和穿传统鞋之间提供了一种妥协。
