利用H/P/Cosmos GaitwayⅡ步态分析跑台,探讨不同步速条件下步态的变化.8名健康大学男生以4,5,6km·h-13种速度在跑步机上行走,采集10 s的连续步态,测力板采样率为100Hz.结果表明:随着步行速度增加,步频、步长、步幅呈显著性的递增;而单步时间、步态周期时间、支撑时间、单足支撑时间及双足支撑时间均出现显著性递减.第一峰值力、质量承受率及蹬地率随步行速度的增加而增加;支撑力却随步行速度增加呈显著性降低;而第二峰值力仅在速度4km·h-1和5km·h-1之间的增加有意义.步态模式随着步行速度的变化而变化.体质量大的人快步走时需要适当控制步行速度,以免地面反作用力过大,对足部造成损伤.
The running gait was analyzed by gait of H / P / Cosmos gaitway Ⅱ, and the changes of gait at different gait speeds were observed. The boys from 8 healthy universities walked on treadmills at speeds of 4, 5 and 6 km · h-13, Continuous gait and force plate sampling rate were 100Hz.The results showed that as the walking speed increased, the step frequency, the step length and the stride rate increased significantly, while the single step time, the gait cycle time, the support time, Support time and support time of both feet decreased significantly.The first peak force, mass bearing rate and tread rate increased with the increase of walking speed, but the support force decreased significantly with the increase of walking speed, while the second peak force Only the speed of 4km · h-1 and 5km · h-1 increase between the significance of the gait mode changes with the changes in walking speed.When the body weight of people walking fast walking speed need to be properly controlled in order to avoid the ground reaction Excessive force, causing damage to the foot.
