摘要
该文研究了人体全身性生理负荷 (用心率作为评价指标 )对人体平衡功能的影响 .通过实验得知劳动生理负荷水平对人体平衡功能影响非常显著 ;人体动摇总轨迹长、左右动摇总轨迹长、前后动摇总轨迹长、动摇速度与心率之间存在很好的线性相关关系 ,并导出了相关的回归模型 .人体生理负荷对人体前后动摇的影响明显大于对左右动摇的影响 人体动摇程度随着劳动生理负荷水平的增加而增加 ,减少劳动生理负荷对于减少作业事故的潜在危险性具有重要意义 .
An experimental study was carried out on the effects of physiological load of workers on body sway. The physiological load was assessed by heart rate of subjects. The results indicated that the effects of physiological load on body sway were highly significant. There are good liner relationship between the heart rate and the total length of body sway, total length of body sway in right left direction, total length of body sway in front rear direction and speed of body sway. The regression models between heart rate and the value of body sway were derived. The effects of physiological load on body sway in front rear direction was stronger than in right left. To lower the workers heart rate during working is the key point to reduce accidents from tumbling down.
