概括
对先天性心脏病 (CHD) 患者来说,准确的运动强度处方是具有挑战性的. 像%HRR和%HRmax这样的常见心率 (HR) 方法可能不有效,通常在炼强度的目标范围之外.
科学领域:
- 心脏病学 心脏病学
- 运动生理学 运动生理学
- 康复 康复 康复 康复
背景情况:
- 对于患有先天性心脏病 (CHD) 的人来说,运动训练至关重要.
- 对运动强度的准确处方在这个人群中是一个重大挑战.
- 目前基于心率 (HR) 估计运动强度的方法在心脏病患者中可能缺乏有效性.
研究的目的:
- 评估高峰心率 (%HR高峰) 和心率储备 (%HRR) 的百分比准确性,用于估计患有冠心病的人的运动强度.
- 为了比较基于HR的不同方法与已建立的氧气吸收 (VO2) 范围对运动强度的有效性.
主要方法:
- 对心肺运动测试 (2009-2017年) 的回顾性审查.
- 运动强度按峰值氧气吸收的百分比分类 (%VO2).
- 通过%HRR和%HR峰值方法获得的HRs与定义强度的参考HRs进行比较.
主要成果:
- %HRR和年龄预测最大HR (%HRmax) 方法显示了最高的准确性,但在65%以下的时间内处于指导范围内.
- %HRmax对轻度 (59%) 和中度 (63%) 的强度最准确.
- %HR峰值对强烈强度 (84%) 最准确,但倾向于低估强度,而%HRR倾向于高估强度.
结论:
- 基于HR的标准方法来估计运动强度可能对许多患有心脏病的人来说不可靠.
- %HRR和年龄预测的%HRmax是最准确的,但对于大约三分之一的研究队列来说仍然不准确.
- 需要进一步的研究来完善心脏病患者的运动强度处方.

730
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.

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.
