【摘要】 目的:研究是运用运动生物力学的手段和方法,采用比利时的足底压力分布测试系统Footscan insole中的平板系统对女大学生不同走路姿势(正常步姿、外八字、内八字)三种不同步姿在正常行走和慢跑时足底压强的测试,探讨两种畸形步姿与正常步态的运动特征,开展人体运动功能评定方法、矫形运动鞋的设计、运动假肢设计方法等研究提供重要的基础依据。方法:采用纯随机的抽样方法,抽取了石家庄450名青年女性进行测试,组间比较采用单因素方差分析,结果:受试者以正常姿势行走时,足部最大压强部位在第2跖骨,以外八字姿势行走时,足部最大压强部位在第1跖骨,以内八字姿势行走时,足部最大压强部位在第3跖骨;受试者以正常姿势慢跑时,足部最大压强部位在2跖骨,外八字姿势慢跑时,足部最大压强部位在第2跖骨,以内八字姿势慢跑时,足部最大压强部位在足跟。结论:步姿不同,足底压强最大的部位就不同,外八字姿势行走时足跟及前掌第1跖骨处的压强大;内八字姿势行走时,前掌第3跖骨处的压强大,慢跑时,足跟处的压强大,这也是畸形步姿下最容易损伤的部位。更多还原

【Abstract】 Objective:Using the means and methods of sport biomechanics and depending on Belgian Footscan insole plate system among female college students,the paper tests the maximum value of plantar pressure in walking and jogging with normal gait,toe and toe in to explore the motion characteristics of gaits.This paper aims to provide the basis for function evaluation,orthopedic sports shoes design and sports prosthesis design.Methods:450 young women from Shijiazhuang are randomly selected as samples to make comparisons between groups by One- Way ANOVA analysis.Results:Subjects with normal posture during walking have their foot maximum force position in the second metatarsal of palm while the abnormal walkers in the heel;during jogging,those with normal posture have their foot maximum force position in the second metatarsal,while the abnormal joggers,in the first metatarsal and the second metatarsal.Conclusion:heel peak of abnormal subjects is greater than that of the normal walkers and the differences are statistically significant(P < 0.01).Because of the poor transition of plantar force from the heel to the whole foot,then to the palm,then the lack of cushioning effect,the heel bears pressure.Walking with abnormal gaits leads to instability for the greater pressure of heel than that of the palm;in jogging,the pressure of the first metatarsal and the second metatarsal is greater than that of the normal with statistically significant differences.更多还原
