摘　　要：Background:Numerous studies about the interaction between footwear(and barefoot) and kinematic and kinetic outcomes have been published over the last few years.Recent studies however lead to the conclusion that the assumed interactions depend mainly on the subjects" experience of barefoot(BF) walking/running,the preferred running strike pattern,the speed,the hardness of the surface,the thickness of the midsole material,and the runners’ level of ability.The aim of the present study was to investigate lower leg kinematics o\’ BF running and running in minimal running shoes(MRS) to assess comparability of BF kinematics in both conditions.To systematically compare both conditions we monitored the influencing variables described above in our measurement setup.We hypothesized that running in MRS does not alter lower leg kinematics compared to BF running.Methods:Thirty-seven subjects,injury-free and active in sports,ran BF on an EVA foam runway,and also ran shod wearing Nike Free 3.0 on a tartan indoor track.Lower-leg 3D kinematics was measured to quantify rearfoot and ankle movements.Skin markers were used in both shod and BF running.Results:All runners revealed rearfoot strike pattern when running barefoot.Differences between BF and MRS running occurred particularly during the initial stance phase of running,both in the sagittal and the frontal planes.BF running revealed a flatter foot placement,a more plantar flexed ankle joint and less inverted rearfoot at touchdown compared to MRS running.Conclusion:BF running does not change the landing automatically to forefoot running,especially after a systematic exclusion of surface and other influencing factors.The Nike Free 3.0 mimics some BF features.Nevertheless,changes in design of the Nike Free should be considered in order to mimic BF movement even more closely.背景:近年来有大量研究描述鞋类(或赤脚)与运动学和动力学结果间的相互作用。但最近的研究结果表明,这种假定的相互作用主要依赖于受试者赤脚走(或跑)的经验,偏好的跑步模式、跑速、地面硬度、鞋底夹层材料厚度及跑步者的能力水平。本研究旨在调查赤脚跑和穿极简鞋跑的下肢运动学,以评价两种情况下赤脚运动学的可比性。为系统比较两种情况,我们在设置测量时监测了上述影响变量。我们的研究假设是,与赤脚跑相比,穿极简鞋跑时的下肢运动学不会改变。方法:37名未受伤且活动积极的受试者,首先赤脚在EVA塑胶跑道上跑,然后穿Nike Free 3.0跑鞋在塔坦室内塑胶跑道上跑。测量下肢三维运动学结果,定量分析脚跟和脚踝的移动。两种跑步情况下均用到皮肤标记。结果:所有受试者赤脚跑时都是脚跟着地模式。赤脚和穿极简鞋跑的区别主要出现在着地初期,矢状面和额状面均有差异。与穿极简鞋相比,赤脚跑触地时脚位更平、踝关节跖屈程度较大,脚跟内翻程度较小。结论:赤脚跑无法使触地模式自动改变为前脚掌着地,尤其是系统地排除了地面及其他影响因素之后。Nike Free 3.0跑鞋能模仿赤脚跑的部分特征,但其未来设计应进一步完善,从而更高程度地模仿赤脚跑的运动特征。
