高强度间歇有氧运动延迟了健康成年人的心率变化恢复. 自主神经系统调节在一个小时内恢复到基线,不管运动强度如何.
科学领域:
- 运动生理学 运动生理学
- 心血管健康 心血管健康
- 自主神经系统功能 自主神经系统功能
背景情况:
- 心率变化 (HRV) 指数反映了自主神经系统 (ANS) 调节.
- 了解HRV对不同运动强度的反应对于临床实践和运动处方至关重要.
研究的目的:
- 在成年人中,系统地审查和元分析HRV对高强度间歇有氧运动 (HIIE) 的反应,与中等强度连续运动 (MICE) 相比.
- 为临床实践提供有关运动强度和恢复的信息.
主要方法:
- 系统地搜索四个数据库,直到2023年3月为随机对照试验.
- 评估HRV指数,包括SDNN,RMSSD,NN50,PNN50,HF,LF和LF/HF.
- 使用RoB 2工具进行偏差风险评估.
主要成果:
- 包括16项研究 (9项元分析),主要是健康的年轻人.
- 在运动后10分钟内,高频 (HF) 和低频 (LF) HRV指数的HIIE恢复到基线较慢 (SMD分别为-0.98和-0.42).
- 1小时后,没有观察到HRV恢复的显著差异. 在6项研究中发现了偏差的高风险.
结论:
- 在运动后的前10分钟内,HIIE会导致HF和LFHRV指数的短暂,延迟的恢复.
- 健康的个体在1小时内将ANS调节恢复到基线水平,无论运动强度如何.
- 临床影响建议监测HIIE后的短期康复.

Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...
Regulation of Heart Rates
The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...

Exercise and Cardiovascular Response
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...
Cardiac Output I:Effect of Heart Rate on 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...
Exercise Stress Test
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.
