抵抗训练显著提高了年轻成年人的心率变化 (HRV) 参数,包括RMSSD和SDNN. 这表明力量训练改善了副交感活动和潜在的心血管益处.
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) 是心血管健康的关键指标.
- 众所周知,有氧运动可以改善HRV,但抵抗训练的影响不太清楚.
研究的目的:
- 研究和比较一个抵抗训练计划对身体活跃的年轻成年人HRV参数的影响.
- 评估力量训练对自主调节的影响,与中等强度运动相比.
主要方法:
- 一项观察性研究涉及24名身体活跃的年轻成年人,分为抵抗训练和中等强度运动控制组.
- 使用极地RS800CX监视器测量休息时的HRV,分析时间域 (RMSSD,SDNN),频域 (HF,LF正常化) 和非线性 (SD1,SD2) 度量.
- 统计分析采用未配对的t测试,显著程度为p < 0.05.
主要成果:
- 与对照组相比,抵抗训练组的RMSSD和SDNN值显著更高 (p < 0.01).
- 在抵抗训练组中,非线性HRV指标SD1和SD2也显著升高,表明副交感活动增加.
- 这些发现表明,在接受抵抗训练的个体中,副交感调节更大.
结论:
- 抵抗训练与增强的副交感调制有关,这是改善自主功能的标志物.
- 这项研究表明,将抗力训练纳入运动规则中,可能会对心血管产生潜在的益处.
- 这些发现有助于了解超越肌肉缩的抵抗运动的生理适应.

Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...
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...
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...
Exercise and Muscle Performance
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
