摘要
通过小学生群体穿运动鞋与暴走鞋的步态,研究运动鞋、无轮暴走鞋、有轮暴走鞋在步行过程中的步行行为特点.用高速摄像机从侧面拍摄小学生穿运动鞋与暴走鞋时的步态过程,分析正常步行时的步长、步频、步速与落地角的步行行为指标特征,检验鞋跟高度差异对步行的影响.结果表明:小学生步行时的最长步长是运动鞋,有轮暴走鞋最短;运动鞋、无轮暴走鞋、有轮暴走鞋的步频、步速与落地角呈现递减趋势;运动鞋与有轮暴走鞋、无轮暴走鞋与有轮暴走鞋的步长、步速与落地角的平均值差异非常显著(P<0.01),运动鞋与有轮暴走鞋、无轮暴走鞋与有轮暴走鞋的步频平均值差异显著(P<0.05).
The purpose of this study is to compare the gait between primary school students walking with sneakers and Heelys. Pedestrian behaviors are observed for the pupils wearing sneakers, Closed-Wheel Heelys（CWH） and Open-Wheel Heelys（OWH）. A high-speed video camera is set up to film the pupils＇ gait at sideline when they are walking along described by four indices, that is, chose step length, stride frequency, walking velocity and landing angle. These indices are analyzed under normal walking condition. Also the impact of varying high-heels on the walking gait is analyzed. The results show that wearing sneakers causes the longest step length while the shortest with OWH. In comparison, wearing sneakers, CWH and OWH leads to decreasing stride frequency, walking velocity, and landing angle. The noticeable difference in averaged measurements is found among step length, walking velocity and landing angle（P〈0.01）, and so is also found in stride frequency（P〈0.05）.
