The aim of this study was to investigate the effects of surface stiffness on multisegment foot kinematics and temporal parameters during running.
Eighteen male subjects ran on three different surfaces (i.e., concrete, artificial grass, and rubber) in both heeled running shoes (HS) and minimal running shoes (MS). Both these shoes had dissimilar sole profiles. The heeled shoes had a higher sole at the heel, a thick base, and arch support, whereas the minimal shoes had a flat base sole. Indeed, the studied biomechanical parameters responded differently in the different footwear during running. Subjects ran in recreational mode speed while 3D foot kinematics (i.e., joint rotation and peak medial longitudinal arch (MLA) angle) were determined using a motion capture system (Qualysis, Gothenburg, Sweden). Information on stance time and plantar fascia strain (PFS) was also collected.
Running on different surface stiffness was found to significantly affect the peak MLA angles and stance times for both HS and MS conditions. However, the results showed that the joint rotation angles were not sensitive to surface stiffness. Also, PFS showed no relationship with surface stiffness, as the results were varied as the surface stiffness was changed.
The surface stiffness significantly contributed towards the effects of peak MLA angle and stance time. These findings may enhance the understanding of biomechanical responses on various running surfaces stiffness in different shoe conditions.
本研究旨在调查跑步过程中表面刚度对多节段足部运动学和时间参数的影响。
18名男性受试者穿着后跟跑鞋（HS）和极简跑鞋（MS）在三种不同表面（即混凝土、人造草皮和橡胶）上跑步。这两种鞋子的鞋底轮廓不同。后跟跑鞋的后跟处鞋底较高，底部较厚且有足弓支撑，而极简跑鞋的鞋底则是平的。实际上，在跑步过程中，所研究的生物力学参数在不同鞋类中的反应有所不同。受试者以休闲模式速度跑步，同时使用运动捕捉系统（瑞典哥德堡的Qualysis）确定三维足部运动学（即关节旋转和内侧纵弓（MLA）峰值角度）。还收集了站立时间和足底筋膜应变（PFS）的信息。
发现在不同表面刚度上跑步对HS和MS两种情况的MLA峰值角度和站立时间均有显著影响。然而，结果表明关节旋转角度对表面刚度不敏感。此外，PFS与表面刚度无关，因为随着表面刚度的变化结果各不相同。
表面刚度对MLA峰值角度和站立时间的影响有显著作用。这些发现可能会增进对不同鞋类条件下各种跑步表面刚度生物力学反应的理解。
