高强度间歇训练 (HIIT) 在康复期间保持心率和氧气吸收的升高. 这种持续的心血管负荷表明,即使在运动停止后,HIIT也会显著影响生理反应.
科学领域:
- 运动生理学 运动生理学
- 心血管反应的反应
- 高强度间歇训练 高强度间歇训练
背景情况:
- 高强度间歇训练 (HIIT) 提高了最大的氧气吸收 (V·O2max).
- HIIT涉及到近最大V·O2或心率 (HRmax) 的延长时间.
- 在运动期间,HIIT协议可以延迟HR和V̇O2,在恢复间隔期间保持高值.
研究的目的:
- 为了比较运动和恢复期间的V·O2和HR反应.
- 在七项研究中分析了各种自行车HIIT协议的数据.
主要方法:
- 104名健康,活跃的参与者 (男性和女性),年龄为24±5岁.
- HIIT协议在持续时间 (30-60秒),强度 (70-85%Wmax) 和恢复 (10-75秒) 方面有所不同.
- 测量包括V̇O2,HR和血液中乳酸度 (BLa).
主要成果:
- 峰值HR达到了90.7 ± 6.2%HRmax.
- 在运动和恢复之间,平均HR (159 ± 14 vs 160 ± 15 b/min) 没有发现显著差异.
- 同样,在运动和恢复之间,没有观察到平均V̇O2 (1.97 ± 0.47对1.98 ± 0.48 L/min) 的显著差异.
结论:
- 在康复期间,HIIT会导致VO2和HR升高.
- 这表明间歇运动后的大量和持续的心血管负荷.
- 这些发现突出了HIIT对生理恢复的重大影响.

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...
