概括

山地自行车 (MTB) 骑手通常在跌倒时使用安全着陆策略,上肢支和踏步是最常见的. 大多数骑手使用多种技术来减轻伤害,与推的做法保持一致.

科学领域:

运动科学运动科学运动科学
生物力学生物力学
伤害预防预防伤害

背景情况:

在山地自行车 (MTB) 中,落很常见,经常发生在高速和具有挑战性的地形上.
虽然大多数MTB落不会导致严重伤害,但这可能归因于骑手使用保护性"安全着陆策略".
现有的研究尚未综合或验证这些通常讨论的策略.

研究的目的:

为了确定山地自行车 (MTB) 骑手是否在实际跌倒时采用推的安全着陆策略.
在现实生活中的MTB事件中确定使用最多和最少的安全着陆策略.

主要方法:

通过在线内容分析和对经验丰富的MTB骑手的调查,确定了11个推的安全着陆策略.
分析了300个现实MTB落的视频录像,使用结构化问卷来评估策略使用情况.
量化了每次秋季使用的策略的频率和数量.

主要成果:

上肢支架 (58.3%),肘部曲 (48.0%),踏步 (47.0%),膝盖曲 (43.0%) 和自行车分离 (40.0%) 是最常见的策略.
最少使用的是伸手抓住 (4.7%),使用手臂保护脸部 (6.3%) 和卸载 (6.7%).
96%的跌倒涉及至少一种推策略,平均每次跌倒使用3.04种策略.

结论:

山地自行车 (MTB) 跌倒触发运动策略与推的伤害避免技术相一致.
这些发现支持常见骑手行为在减轻跌倒相关伤害方面的有效性.
未来的研究应该探索运动干预措施,以加强安全降落反应和预防MTB伤害.

Survey Safety

Survey Safety

Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Friction: Problem Solving

Friction: Problem Solving

Friction is an essential force that influences the motion of objects in daily life. Depending on the situation, it can be either beneficial or problematic. Consider a bus with a mass of three megagrams and its center of mass at a specific point, moving along a banked road at a constant speed. The coefficient of static friction between the tires and the road is 0.5. Find the maximum angle of the banked road at which the bus would not slip or tip.
Initially, a visual representation of the...
