| 摘 要： | 目的:比较受试者穿着倒跟运动鞋和普通运动鞋在跑台上行走时,躯干和下肢的运动学特征,以及躯干和下肢肌肉活动特征。方法:13名健康女大学生志愿受试者,分别穿着倒跟和普通两种运动鞋在测试跑台上以1.33 m/s的速度行走。采用摄像机和Ariel运动解析系统记录和分析矢状面的行走的运动学参数。采用BTS表面肌电系统采集和分析优势侧竖脊肌、腹直肌、股直肌、股二头肌、胫骨前肌和腓肠肌外侧头表面肌电。结果:与普通运动鞋相比,穿着倒跟鞋行走时,步频加快、步幅缩短;躯干和髋关节最大伸展角度、膝关节最大弯曲角度、踝关节支撑相的背屈角度以及踝关节关节活动范围显著增加(P<0.05);胫骨前肌、腓肠肌的外侧头和股二头肌积分肌电、肌肉激活时间和平均振幅显著增加(P<0.05)。结论:穿着倒跟鞋行走改变了躯干和下肢的运动学特征,并增加下肢胫骨前肌、腓肠肌外侧头和股二头肌的活动。 |
