摘　　要：目的将步态特征与体质状况相结合,分析对比不同体质的大学生自然行走时步态特征的差异性和规律,通过步态特征来反映大学生的体质状况,为今后如何提高大学生的体质提供一定的理论依据。方法选取119名大学生作为研究对象,对大学生的体质状况进行测试,按照《国家学生体质健康标准(2014年修订)》将测试成绩进行分类;然后对分类后的大学生,利用足底压力测试系统进行自然行走时步态特征的测试,选择不同足支撑期分期所占百分比、足底各区域压强峰值、足底不同区域所受冲量百分比、足弓指数、足轴角为步态特征参数;最后,对比分析体质不同的大学生其步态特征的差异性。结果受试者在自然行走时,足轴角的大小之间差异具有统计学意义。结论大学生的体质状况与步态特征有密切关系。可根据步态特征的差异性,进一步了解大学生的体质状况,为今后设计有针对性的大学生体育锻炼方案提供客观依据,改善大学生的体质状况。Objective By combining gait features with physical condition,this paper aims to analyze and compare the differences and rules of natural gait feature among college students with different physical condition. The physical condition of college students will be reflected by the gait features,which provides certain theoretical basis for improving the physical condition of undergraduates. Methods One hundred and nineteen undergraduates were selected as research subjects and their physical condition were tested and thus classified according to National Fitness and Health Standard of Students（revised in 2014）. The natural trait features of classified students were tested through the test system of plantar pressure. The latent parameters included the percentage of different foot support periods,the peak value of pressure among different pelma areas,the percentage of pulse received by different pelma areas,arch index and axial angle of the foot. Finally,the differences of gait features were compared and analyzed.Results There was a significant difference in the size of axial angles among subjects walking naturally.Conclusions The physical condition is closely related tothe gait feature of undergraduates. The physical condition of undergraduates can be further understood on the basis of differences in gait features,which can provide objective evidence aiming at devising undergraduateoriented physical training scheme and thus promoting physical condition of undergraduates.
