Many people work in a sitting position where they have to use their upper extremities and hands. Muscle activity in sitting position is affected by the chair height of, the height of the worktable, and the distance to the working target.
The purpose of this study is to investigate differences in muscle activity between men and wemen at different chair heghts and working distances.
Surface electromyography (EMG) was employed to determine the muscle activity of the upper limbs and the trunk, while an arm-stretching task was performed in a sitting position.
Women's muscle activity was higher than that of men in most muscles as the chair height and working distance changed.
As the height of the chair or the working distance was changed, muscle activity was greater in women than in men for most of the muscles analyzed. Under the same conditions, women may feel more muscle fatigue than men, so it is necessary to consider gender in the working environment.
许多人在坐姿下工作,需要使用上肢和手部。坐姿下的肌肉活动受到椅子高度、工作台高度和工作目标距离的影响。
本研究旨在探讨不同椅子高度和工作距离下男女肌肉活动的差异。
采用表面肌电图(EMG)测定上肢和躯干的肌肉活动,同时进行坐姿伸展手臂任务。
随着椅子高度和工作距离的变化,女性的肌肉活动在大多数肌肉中高于男性。
在相同条件下,女性可能比男性更容易感到肌肉疲劳,因此在工作环境中需要考虑性别因素。
