消防员装备在不同任务中对生物力学产生不同的影响,影响肌肉活动和关节力量. 这些数据有助于改善消防员的人体工程学,培训和伤害预防策略.
科学领域:
- 职业生物机械学
- 运动科学 运动科学
- 人体工程学就是人体工程学.
背景情况:
- 消防工作在身体上要求很高,并且与高受伤率有关.
- 了解消防任务的生物力学要求对于预防伤害至关重要.
研究的目的:
- 开发一套执行关键任务的消防员的生物机械数据集.
- 分析防护装备对生物力学负荷和活动不对称性的影响.
- 为改善消防员人体工程学,培训和伤害预防提供见解.
主要方法:
- 采集了20名专业消防员的生物机械数据,使用了运动捕捉.
- 进行肌肉骨模拟以分析关节力量和肌肉活动.
- 在装备携带,软管拖动,机身拖动和爬楼梯时,与没有消防装备的生物力学结果进行比较.
主要成果:
- 消防员的装备显著改变了生物力学,以一种依赖于任务的方式.
- 干肌肉活动增加,关节反应力上升,脚扭矩增加在身体拖动与轮.
- 用轮爬楼梯显示脚扭矩下降,但膝盖和部扭矩增加,表明靠近关节的依赖.
- 腿部肌肉活动双边增加,除了在软管拖拉. 观察到不对称性,左膝盖扭矩更高,右脚/膝盖力更大.
- 左上半身在拖拉任务中产生了更多的能量.
结论:
- 消防员装备影响生物力学负载和肌肉激活模式.
- 具体任务分析对于理解轮效应至关重要.
- 识别的不对称性和关节负荷模式可以为有针对性的伤害预防策略和培训计划提供信息.

Absolute Motion Analysis- General Plane Motion
As the drone's propellers rotate, an upward force is generated that counteracts the force of gravity, enabling the drone to lift off from the ground. This initial movement of the drone is along a straight path, representing a form of translational motion. In this phase, every point on the...
Membrane Asymmetry Regulating Transporters
Flippase
Eukaryotic flippases are type-IV P-type ATPases or P4-ATPases belonging to P-type ATPase family proteins that are membrane-bound pumps involved in the ATP-mediated transport of ions and molecules across the membrane. Flippases flip specific phospholipids from the outer to the inner leaflet of a membrane. All P4-ATPases have one...
Relative Motion Analysis - Acceleration
Relative Motion Analysis - Velocity
When an external force is exerted, it sets the crank into a rotational movement. This, in turn, instigates the motion of the connecting rod, leading to what is referred to as a general plane motion. This process involves two key points - point A on the connecting rod...
Relative Motion Analysis using Rotating Axes
However, to express the relative position of point B relative to point A, an additional frame of reference, denoted as x'y', is necessary. This additional frame not only translates but also rotates relative to the fixed frame, making it...
