Estimation of the Physical Quantities01:05

Estimation of the Physical Quantities

4.1K
On many occasions, physicists, other scientists, and engineers need to make estimates of a particular quantity. These are sometimes referred to as guesstimates, order-of-magnitude approximations, back-of-the-envelope calculations, or Fermi calculations. The physicist Enrico Fermi was famous for his ability to estimate various kinds of data with surprising precision. Estimating does not mean guessing a number or a formula at random. Instead, estimation means using prior experience and sound...

Exercise Stress Test

166
Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

  • 时间感知研究 时间感知研究

背景情况:

  • 在24名健康成年人 (12名女性,12名男性) 接受调查后,研究了在消耗性运动之前和之后的时间估计.
  • 检查了生理兴奋,特别是血中乳酸盐水平的增加对时间判断的影响.

研究的目的:

  • 为了比较时间间隔估计能力 (1-5秒) 在有和没有心理计数的条件下.
  • 评估全面运动和随后的生理变化对时间感知的影响.

主要方法:

  • 参与者执行了时间估计任务,包括心理计数和非心理计数.
  • 运动前后测量时间感知和血中乳酸盐水平.

主要成果:

  • 运动显著改变了时间感知,影响因估计方法而异.
  • 头脑计数导致运动后时间过度估计减少.
  • 非心理计数任务显示,运动后的表现下降.
  • 在时间估计变化中没有观察到基于性别的差异.

结论:

  • 血中乳酸水平升高可能会起到生理性唤醒的作用,导致时间感知变化.
  • 在没有精神计数的情况下,时间感知障碍背后的确切机制仍然不清楚.
