概括
高度可调的办公桌没有显著改变姿势摇摆. 计算机任务,特别是鼠标使用与键盘使用,对姿势变化和部不适有更大的影响.
科学领域:
- 人体工程学就是人体工程学.
- 人类因素 人类因素
- 肌肉骨健康 肌肉骨健康
背景情况:
- 长时间坐着与肌肉骨健康不良影响有关.
- 可调节高度的办公桌被提议通过增加姿势变化来减轻这些影响.
- 姿势摇摆 (头部和干部运动) 是姿势变化的关键指标.
研究的目的:
- 为了研究可调高度桌子对姿势摇摆的影响.
- 为了在键盘和鼠标任务中比较姿势摇摆,坐在和站立的位置.

01:11Anatomical Positions
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

01:24Normal and Tangetial Components: Problem Solving
Consider a man with a mass of 70 kg seated in a chair connected to a pin support through a member BC. If the man maintains an upright position, the task is to determine the horizontal and vertical reactions of the chair on the man when the member makes a 45° angle with the horizontal. At this moment, the man has a speed of 5 m/s, increasing at a rate of 1 m/s².
