| 摘 要： | 将交谊舞练习者分为跳舞时重心起伏突然(不平稳)和平稳型两类,旨在探索不同舞姿练习者在正常步行中是否表现出不同的撞击震荡吸收能力。测试中要求受试者以各自正常的步速行走,在胫骨和头部分别用体表加速度计记录其加速度变化,并同步摄下其步态而得到相关运动学参数。结果表明:正常行走时平稳型练习者的震荡吸收较不平稳型好;不平稳型练习者行走时的膝角、踝角峰值和踝关节角度变化范围较平稳型均大,且有显著性。认为,采用合理的舞姿(平稳型)将有利于提高交谊舞练习者的整体震荡吸收能力和改善踝关节背屈控制能力和全身协调能力。 |

| Abstract: | Shock attenuation during walking had been linked to many kinds of injuries.The aim of this study was to examine whether dancers with different dancing patterns would show different impact shock attenuation when walking.Subjects dancing with abrupt rises and falls were selected as one group,and those who moved their center of mass smoothly when dancing were selected as another group.They were asked to walk at their preferred speed when the tibia and head accelerations were recorded using skin-mounted accelerometers.And their gaits were filmed at the same time to get the kinematic variables.The group dancing smoothly showed better shock attenuation than the other group.And the group dancing with abrupt rises and falls showed significant higher values of the maximum knee angle,maximum ankle angle and total angle change of ankle joint statistically.The results indicated people dancing with proper principle(smooth) were associated with good shock attenuation ability and good ankle dorsiflexion control. |
| Keywords: | social dancing shock attenuation walking ankle joint |
