男性和女性运动员对缓慢呼吸的自主调节反应不同. 虽然心率的变化和血压的变化有所不同,但自发巴罗反射灵敏度在两性之间保持不变.
科学领域:
- 心血管生理学心血管生理学
- 自主神经系统的调节规则
- 运动生理学 运动生理学
背景情况:
- 心率变化 (HRV),血压变化 (BPV) 和自发巴罗反射灵敏度 (BRS) 是自主心血管控制的关键指标.
- 之前的研究表明HRV和BRS的性别差异,但不是在运动员身上.
- 这项研究调查了运动员之间自主调节标志物的性别差异.
研究的目的:
- 为了比较男性和女性运动员之间的自主调节标志物 (BPV,HRV,BRS).
- 评估控制慢呼吸方案对两性运动员这些标记物的影响.
主要方法:
- 100名男性和65名女性运动员接受了基线季前评估.
- 休息时的节拍血压和R-R间隔使用光电脉学和心电图进行记录.
- 进行了5分钟的缓慢呼吸方案 (6次/分钟),随后进行了光谱和线性分析,包括BRS计算.
主要成果:
- 与女性相比,男性运动员的平均心率,RR间隔SD2/SD1和HRV%低频功率显著降低.
- 男性运动员在受控呼吸期间也表现出更高的血压高频功率.
- 在男性和女性运动员之间,没有观察到任何自发巴罗反射敏感度参数的显著差异.
结论:
- 男女运动员之间的心率变化和血压变化对缓慢呼吸的反应不同.
- 在男性和女性运动员之间,自发的呼吸反应对缓慢呼吸的敏感性反应并不不同.
- 这些发现突出了运动员的性别特异性自主适应.

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...
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...

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...
