摘　　要：利用Footscan足底压力测试系统和Codamotion三维动作捕捉系统,采集45名男性和45名女性自然行走过程中足底与地面依次接触的时间和下肢关节角度随时间的变化。重点对男性和女性步态周期中支撑期时相和一个完整步态周期内下肢关节角度随时间的变化进行比较分析,结果表明:1)男性和女性的前掌触地期和离地期时长存在显著性差异;2)脚跟着地后至脚跟离地期间,男性踝关节角度显著大于女性踝关节角度;3)脚跟着地后至全掌触地但脚跟未离地期间,男性膝关节角度显著小于女性膝关节角度,但摆动初期男性膝关节角度显著大于女性。Data was collected by Footscan plantar pressure measure system and Codamotion 3-D motion capture system.The differences of ankle angle and knee angle between young women and men were compared. The differences of phase were also compared. Results show that： 1） the duration of forefoot contact phase and forefoot push off phase was significant different in gender; 2） the degree of ankle angle in man was significant greater than women after initial foot contact to heel off; 3） the degree of knee angle in men was significant less than women after initial foot contact before heel off, but the degree of knee angle in men was significant greater than women at early swing phase.
