摘要:
为研究步态参数影响个体滑倒风险的内在机理，对男女个体分别在行走、跑步2种运动姿态时的步态参数进行对比分析。利用三维测力跑台获取并分析不同速度、坡度工况下的个体步长、步宽和最大足底正压力数据。研究结果表明：消除身高影响后，跑步姿态的男性个体步长比同速度的女性个体步长小4 cm左右；行走姿态的男性个体最大足底正压力和重力的比值约为女性个体比值的1.1倍；跑步姿态时，随着个体步长的增大，男女个体的步频基本保持在2.6~2.8步/s；在跑步姿态时，个体会通过维持步频、增大步长（增大足底与地面作用力或跨步夹角）的方式来提高运动速度。研究结果可为后续个体滑倒风险研究提供参考。
Abstract:
To investigate the internal mechanism of gait parameters affecting the slip risk of individual,the comparative analysis was conducted on the gait parameters of male and female individuals under two motion postures of walking and running.The step length,step width,and maximum plantar positive pressure of individuals under different speeds and gradients were measured and analyzed by using a three-dimensional force-measuring treadmill.The results show that after eliminating the influence of height,the step length of male individuals in running posture is about 4 cm smaller than that of female individuals at the same speed.The ratio of maximum plantar positive pressure to gravity of male individuals in walking posture is about 1.1 times that of female individuals.In the running posture,with the increase of individual step length,the step frequency of male and female individuals remains basically at 2.6~2.8 steps/s.In the running posture,the individuals will increase the motion speed by maintaining the step frequency and increasing the step length (increasing the force between plantar and ground or the step angle).The research results can provide reference for the subsequent study of individual slip risk.
