概括
临界速度 (CS) 和临界功率 (CP) 可以从习惯性训练数据,时间试验或休跑步者的3分钟全力测试中可靠地估计. 然而,超过临界速度 (D') 和超过临界功率 (W') 的工作估计显示出有限的协议,需要谨慎的解释.
科学领域:
- 运动生理学 运动生理学
- 运动科学 运动科学 运动科学
- 生物机械分析 生物机械分析
背景情况:
- 准确的生理标记,如临界速度 (CS) 和临界功率 (CP),对于耐力运动的训练处方至关重要.
- 估计这些标记物通常涉及最大的努力,这对休跑者来说可能很苛刻.
- 替代数据来源,如习惯性训练 (HAB),时间试验 (TTs) 和3分钟全力测试 (3MTs) 正在探索它们的实用性.
研究的目的:
- 为了比较常规训练 (HAB),计时试验 (TTs) 和休跑步者的3分钟全力测试 (3MTs) 中获得的临界速度 (CS) 和CS (D) 以上的工作,以及临界功率 (CP) 和CP (W) 以上的工作.
- 评估3MT对这些生理标记的测试-重新测试可靠性.
- 确定远程数据收集方法是否可以提供耐力性能参数的有效估计.
主要方法:
- 23名休跑者参加了超过8周的比赛,使用脚记录速度,高度和功率输出.
- CS和D',CP和W'从HAB数据中的最佳3分,7分和12分钟段计算出来.
- 估计还来自于在第7周和第8周进行的3次TTT和3次3MT.
主要成果:
- 从HAB,TT和3MT获得的CS/CP估计之间没有发现显著差异.
- 在HAB和TT之间观察到CS (r = .669) 和CP (r = .916) 的强烈一致.
- 对于D'/W'估计,发现的一致性有限,尽管CS/CP显示出3MT的优异的测试-重新测试可靠性.
结论:

Journal Bearings
Journal bearings are mechanical components that support and provide lateral stability to rotating shafts and axles. They are crucial in reducing friction, wear, and vibration in machinery such as engines, turbines, and pumps. The principle behind journal bearings is forming a thin lubricant film between the bearing surface and the rotating shaft, which minimizes direct contact and reduces frictional forces.

Mechanical Efficiency of Real Machines
The mechanical efficiency of a machine is a fundamental concept that describes how effectively a machine can convert input work into output work. According to this concept, the efficiency of a machine is equal to the ratio of the output work to the input work. An ideal machine, meaning a machine that has no energy losses, has an efficiency of one. This implies that the input work and the output work are equal.
However, in reality, no machine can be truly ideal, and all of them experience some...
