引き操作における身体負担の評価方法に関する研究

抄録

The objective of this study is to evaluate the anthropometric data and physiological stress for universal design and barrier free design. With consideration that the working height influences on the physical load, working posture and COP(center of pressure) have been studied with respect to pulling and exercises with upper extremities. The results of perceived posture shows that the load level at olecranon height is higher than that at metacarpal head height. The result of COP measurement also indicates significant differences in the peak loads between at olecranon height and at acromion height. On the other hand, the load level of normal pulling exercise is highest at eye height. Furthermore, a correlation is found in loads between the younger and the aged. To illustrate the mechanism of physiological stress, it will be necessary for us to examine physiological characteristic data in detail.
