摘要
目的:探讨依据跟掌高度比例关系确定的鞋底类型和步行速度对行走相关肌群表面肌电平均振幅(AEMG)的影响,为研究行走神经肌肉运动控制规律和研制具有保健作用的各类运动鞋提供科学依据。方法:10名健康青年男性志愿者,穿着具有不同类型鞋底的运动鞋(负跟鞋、平跟鞋、中跟鞋和船型鞋),分别以0.82 m/s和1.64 m/s速度匀速行走。检测行走相关肌群(身体右侧的胫骨前肌、内侧腓肠肌、比目鱼肌、多裂肌、竖脊肌、股外肌)表面肌电平均振幅。结果:双因素方差分析结果表明,步行速度对各被检肌群AEMG都有显著影响,鞋底类型对竖脊肌(F=5.52,P=0.002)和比目鱼肌(F=4.26,P=0.008)有显著影响,两者不存在交互作用。多重比较发现,穿着船型鞋和负跟鞋快速行走时竖脊肌AEMG显著高于平跟鞋和中跟鞋,穿着船型鞋时比目鱼肌AEMG显著高于其他三种鞋;慢速步行条件下鞋底类型对被检肌群无显著影响。结论:鞋底类型可以改变人体在快速行走时部分行走相关肌肉的平均肌电水平,其原因可能与鞋底类型改变所引起的行走姿势和神经肌肉运动控制模式发生改变有关。
Objective：To study the effects of shoe type and walking speed based on the rate between the height of heel and palm to AEMG of walking-related muscles,and provide scientific basis for developing various types of sport shoes that have health-care functions.Methods：10 healthy young males wear different shoes（negative heel shoes,flat shoes,middle-heeled shoes and boat shoes） with even speed（keep speed in 0.82 m/s and 1.64m/s）.Surface electromyography signals were collected from right side erector spinal muscle,multifidus muscle,soleus muscle,tibialis anterior muscle,vastus lateralis quadriceps femoris muscle and medial gastrocnemius muscle and average EMG were calculated.Results：A two-factor analysis of variance showed that walking speed had significant effect on AEMG of all of the muscles and shoe soles had significant effect on AEMG of erector spinal muscle（F=5.52,P=0.002） and soleus muscle（F=4.26,P=0.008）.There was no interaction between them.After multiple comparison,it was found that AEMG of erector spinal muscle was significantly higher while wearing boat shoes and negative heel shoes compared with wearing middle-heeled shoes and flat shoes while walking at a high speed.And AEMG of soleus muscle was higher while wearing boat shoes compared with wearing other three shoes while walking at a high speed.There was no significant difference on AEMG of all the muscles between shoes while walking at a low speed.AEMG of all of muscles was higher while walking at a high speed compared with walking at a low speed.Conclusion：The shoe sole type can change AEMG of related muscles while walking at a high speed.The reason could be that the change of shoe sole type caused the change of walking posture and control mode of neuromuscular activity.
