| Research Abstract |
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.
