久坐对脊椎肌肉sEMG信号的影响OA北大核心CSCDCSTPCD
The effect of sedentary on surface electromyographic activities of lumbar muscles
采集18名女性受试者在不同久坐时间下,颈夹肌和竖脊肌在最大用力收缩(MVC)过程中的表面肌电(surface electromyography,sEMG)信号,分别考察其初始1.5 s的线性时频指标AEMG、MPF、非线性分析指标%DET的差异,以及全程MVC过程中M PF的变化趋势,以探讨久坐对脊椎肌肉活动水平和功能状态的影响.发现:在久坐前、久坐1.5h、久坐3h之后3种状态下,颈夹肌和竖脊肌在MVC的前1.5s信号中,其时频信号AE-M G…查看全部>>
The aim of this study is to investigate the relation between sedentary and the variability of surface electro-myography (sEMG) activity of lumbar muscles .Eighteen female participants performed three MVC tests (before testing ,keep sitting 1 .5 h and 3 h) .sEMG signals were recorded from the left splenius cervicis and left erector spi-nae simultaneously .Results revealed that the linear indices AEMG ,MPF and the non-linear indices % DET did not changed…查看全部>>
