虚拟现实跑步速度影响男性运动员的时间感知, 更快的光流使时间感觉更短,但没有影响耐力或疲劳水平.
科学领域:
- 运动生理学
- 运动科学
- 虚拟现实应用
背景情况:
- 视觉反对于运动至关重要,
- 虚拟现实为训练提供了沉浸式环境,但它对生理和感知反应的影响需要进一步研究.
- 了解虚拟现实中的视觉线索如何影响运动员的体验是优化训练方案的关键.
研究的目的:
- 调查虚拟环境中的光流 (OF) 速度对跑步机运行中的感知疲劳,疲劳时间 (TTE) 和时间感知的影响.
- 分析感知疲劳的潜在决定因素,包括身体压力,努力,情感价值和兴奋.
- 确定VR运行的时间感知是否会影响耐力表现.
主要方法:
- 十名男性耐力运动员完成了两次随机,单盲,交叉跑步,
- 在虚拟环境中进行跑步机匹配的OF (100%) 或加速的OF (170%).
- 测量了感知疲劳,TTE和心理生理反应,以及压力,努力,情感价值和兴奋的动态.
主要成果:
- 光学流速没有显著影响到疲劳的时间 (TTE) 或心理生理反应.
- 在这两种情况下,参与者认为运行时间比实际时间短 ("时间飞过").

Blood Flow
Blood is pumped by the heart into the aorta, the largest artery in the body, and then into increasingly smaller arteries, arterioles, and capillaries. The velocity of blood flow decreases with increased cross-sectional blood vessel area. As blood returns to the heart through venules and veins, its velocity increases. The movement of blood is encouraged by smooth muscle in the vessel walls, the movement of skeletal muscle surrounding the vessels, and one-way valves that prevent backflow.
Exercise and Cardiac Output
Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.

Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart rate...

Velocity and Acceleration in Steady and Unsteady Flow
In fluid mechanics, velocity and acceleration are key concepts for analyzing particle motion in both steady and unsteady flow. Consider a fluid particle moving along a pathline, where its velocity depends on its position and time. The particle's acceleration is obtained by differentiating the velocity with respect to time.
The acceleration can be generalized to any point in the flow, and expressed as components along three perpendicular directions, representing changes in velocity over time.

Rapidly Varying Flow
Rapidly varying flow (RVF) in open channels is characterized by abrupt changes in flow depth over a short distance, with the rate of depth change relative to distance often approaching unity. These flows are inherently complex due to their transient and multi-dimensional nature, making exact analysis difficult. However, approximate solutions using simplified models provide valuable insights into their behavior.Key Features of Rapidly Varying FlowRVF is commonly observed in scenarios involving...
