不同材料地板的心率变异性研究

RESEARCH OF HEART RATE VARIABILITY OF DIFFERENT MATERIAL FLOORS

记录人赤脚接触地板时的R-R间期值,研究接触这些材料时心率变异性(HRV)时域指标的变化情况。实验结果表明,与正常状态相对照,接触各种材料时,心率变异指标SDDN、RMSSD、PNN50、HRVI均有所减小,表明副交感神经活动水平下降,交感神经活动张力增加,自主神经活动状态发生改变,但未失去其均衡性;各种材料之间对比显示,接触木质材料及竹材地板时的生理指标变化不大,而接触瓷砖时的变化幅度要大一些表明接触木制材料时所受的刺激要小于接触瓷砖时所受的刺激。

Record the R-R interval values when people contact with the floors barefoot,and to research the indexes changes of time-domain of heart rate variability when contact with those materials.The results showed that when contacting with diverse wood floors,the heart rate variability indexes(such as SDNN,RMSSD,PNN50,HRVI) were all less than normalcy,proved that the excitement of sympathetic nervous strengthened,while the activity of parasympathetic nerves weakened,And the activity of autonomic nervous system had ...
