高强度功能训练 (HIFT) 作为"时间回合" (RFT) 诱导的生理压力比"每分钟每分钟" (EMOM) 协议更大. 与EMOM相比,RFT可能提供更好的心肺呼吸系统刺激.
科学领域:
- 运动生理学 运动生理学
- 运动科学 运动科学 运动科学
- 高强度功能训练 (HIFT) 是指高强度的功能训练.
背景情况:
- 高强度功能训练 (HIFT) 通常涉及最小的休息时间,例如"时间回合" (RFT) 或"尽可能多的回合或重复" (AMRAP).
- 另外,HIFT可以结合规定的休息间隔,如"每分钟每分钟" (EMOM),可能改变生理反应.
研究的目的:
- 为了比较EMOM和RFT HIFT协议之间的生理反应.
- 调查规定休息间隔与最小休息对代谢,心血管和感知标记在匹配的总工作量HIFT期间的影响.
主要方法:
- 12名受过培训的个人 (6名男性,6名女性) 完成了两个HIFT协议:EMOM和RFT,匹配了总工作量.
- 这两种方案都包括五轮的动力清洗,杆拉升,重推推进器和Burpees.
- 测量的生理标志物包括心率 (HR),氧气消耗 (VO2),感知劳力的评分 (RPE),血液乳酸 (BLA),肌酸激酶 (CK),运动后过量氧气消耗 (EPOC) 和肌肉氧气和 (SmO2).
主要成果:
- 在EMOM和RFT之间的时间域,HR,VO2,RPE和EPOC-AUC之间观察到显著差异,RFT引起更高的值.
- 在EMOM协议中,与RFT相比,运动后血乳酸 (BLA) 显著降低.
- 在两种方案中,肌酸激酶 (CK) 水平从运动前到运动后显著增加,两者之间没有显著差异.
结论:
- 与EMOM协议相比,RFT协议引起了更大的整体生理压力,突出了休息间隔结构的重大影响.
- RFT可能提供更实质性的心肺呼吸刺激,而EMOM可能更有利于训练有素个体的技术改进和恢复.

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...
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...

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...
