项目摘要

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.

作为劳动强度的评价指标，测定刚工作后的重心变动，得到以下结果。(1)以感应转台作为视觉刺激，测量重心波动，在静止状态下，（双腿垂直），重心移动量增加率为10.8%，重心点距增加率为2.6%，没有感应转盘来刺激视觉。(2)当不使用感应转台进行视觉刺激时，在单腿休息（一条腿垂直）时，重心移动量的增加率为91.6%，重心点距离的增加率为11.5%。然而，当使用感应转台进行视觉刺激时，重心移动量的增加率增加到248.4%，重心点距离的增加率增加到77.2%。对于这些事实，它表明了通过重心波动的测量分析来估计疲劳程度是可能的。(3)工作强度与RPE、心率增快率呈强相关。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。而在特定负荷下，RPE和心跳增加率作为估计劳动强度的方法是有效的。
