3-Dimension Analysis of Human Body Load and Evaluation Method of RPE

工作后立即测量重心波动作为劳动强度的评价指标，并对以下结果进行了澄清。(1)使用感应转台进行视觉刺激并测量重心波动时，在休息状态下（双腿垂直均做），与不使用感应转台进行视觉刺激的情况相比，重心运动量的增长率增加了10.8%，重心点距离的增长率增加了2.6%。(2)不使用感应转台进行视觉刺激时，在单腿休息时（单腿垂直），重心运动量的增长率为91.6%，重心点距离的增长率为11.5%。而采用感应转台进行视觉刺激时，重心运动量的增幅达到248.4%，重心点距的增幅达到77.2%。对于这些事实，它暗示了可以通过对重心波动的测量分析来估计疲劳程度的事情。(3)工作强度，与RPE、心跳加速率呈较强的相关性。此外，在每天移动的考生和不移动的考生之间，数据承认存在差异。而在比载工况下，RPE和心跳加速率作为估算工作强度的手段是有效的。

As the evaluation index of the labor strength, center of gravity fluctuation immediately after working was measured and the following results were cleared.(1) When an induction turntable was used as the sight stimulation and center of gravity fluctuation was measured, in the rest condition (both vertical of the leg being done), 10.8 % of rates of increase of the center of gravity movement quantity and 2.6 % of rates of increase of the center of gravity point distance increased compared with the case, which didn't have an induction turntable for the sight stimulation.(2) When not using an induction turntable for the sight stimulation, in the one leg rest one leg's being vertical), 91.6 % of rates of increase of the center of gravity movement quantity, 11.5 % of rates of increase of the center of gravity point distance were shown. However, when using an induction turntable for the sight stimulation, the rate of increase of the center of gravity movement quantity increased to 248.4 % and the rate of increase of the center of gravity point distance increased to 77.2 %. As for these facts, it suggests the thing about which it is possible to estimate a degree of the weariness by the measurement analysis of the center of gravity fluctuation.(3) The work strength, and RPE, the rate of increase of the heartbeat showed strong correlation. Also, between the daily moving examinee and the examinee that isn't moving, a difference was admitted by the data. However, as the means of estimating work strength in case of specific load work, RPE and the rate of increase of the heartbeat were effective.
