本研究的目的是调查有经验的（EW）和无经验的（IEW）中度高跟鞋穿着者在慢跑和跑步时下肢运动学和动力学的差异。11名经验丰富的女性穿着中等高跟鞋和11个匹配的控制参加了慢跑和跑步测试。一个Vicon运动分析系统被用来捕捉运动学数据和一个奇石勒力平台被用来收集地面反作用力（GRF）。慢跑和跑步速度无显著性差异。与IEW相比，EW在每个相应的速度上都采用了较大的步长（SL）和较低的步频（SF）。在运行过程中，EW使SL显著增大，而IEW使SL和SF均显著增大。运动学数据显示，IEW在站立阶段通常具有更大的关节运动范围（ROM）和峰值角度。IEW内速度效应不明显。EW在跑步过程中表现出显著增加的最大垂直GRF（F-z2）和垂直平均负荷率（VALR），这可能是由过大的步幅造成的。这些都表明，EW和IEW都在高风险的关节损伤时，运行在中等高跟鞋。对于必须穿着中高跟鞋进行跑步的穿着者来说，控制关节稳定性并有意识地平衡SL和SF至关重要。(C)© 2016 Elsevier B.

The aim of this study is to investigate the differences in lower limb kinematics and kinetics between experienced (EW) and inexperienced (IEW) moderate high-heel wearers during jogging and running. Eleven experienced female wearers of moderate high-heel shoes and eleven matched controls participated in jogging and running tests. A Vicon motion analysis system was used to capture kinematic data and a Kistler force platform was used to collect ground reaction force (GRF). There were no significant differences in jogging and running speed respectively. Compared with IEW, EW adopted larger stride length (SL) with lower stride frequency (SF) at each corresponding speed. During running, EW enlarged SL significantly while IEW increased both SL and SF significantly. Kinematic data showed that IEW had generally larger joint range of motion (ROM) and peak angles during stance phase. Speed effect was not obvious within IEW. EW exhibited a significantly increased maximal vertical GRF (F-z2) and vertical average loading rate (VALR) during running, which was potentially caused by overlong stride. These suggest that both EW and IEW are at high risk of joint injuries when running on moderate high heels. For wearers who have to do some running on moderate high heels, it is crucial to control joint stability and balance SL and SF consciously. (C) 2016 Elsevier B.V. All rights reserved.
