概括
主观的运动强度报告对于评估心血管结果是不可靠的. 客观测量对于准确评估运动员的运动负担至关重要.
科学领域:
- 运动生理学 运动生理学
- 心血管健康 心血管健康
- 运动科学 运动科学 运动科学
背景情况:
- 准确量化运动强度对于理解累积运动和心血管结果之间的关系至关重要.
- 运动负担,计算为强度和持续时间的积分,通常使用主观自我报告来估计,这些自我报告可能缺乏准确性.
研究的目的:
- 在耐力运动员中,评估主观自我报告的运动强度 (RPEWord和RPEBorg) 与客观措施 (心率,功率) 相比的准确性.
- 为了确定不同的主观和客观的运动强度指标在骑自行车训练期间和之后之间的协议.
主要方法:
- 40名耐力运动员 (41-69岁,训练超过10年) 进行了42公里的户外自行车测试.
- 持续测量心率和输出功率 (瓦特).
- 在运动期间和运动后30分钟使用Word和Borg尺度收集感知劳动力 (RPE) 的评级.
主要成果:
- 主观的RPE是高度可变的,低估了客观的运动强度指标.
- 在运动后30分钟报告时,RPE尺度和客观测量 (心率,METs) 之间发现不太一致.
- 在运动期间,RPEWord和RPEBorg之间的协议是好的,但在运动后显著下降.
- 较不健康的运动员表现出不同的心脏和新陈代谢概况,与更健康的运动员相比,心脏负担较大,但新陈代谢负担较低.
结论:
- 自我报告的运动强度指标 (MET,心率负担) 应谨慎解释.
- 客观的运动强度测量对于全面评估与长期运动方案相关的风险和益处是必要的.

01:20Exercise and Cardiovascular Response
739
Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

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.
