百分比的三角形 (%Δ) 方法显示在规定高强度间歇训练强度的高变性,表明它没有有效地规范个人炼. 这种变化超过了日复一日的波动,表明了%Δ方法本身的局限性.
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
- 培训要求 培训要求 培训要求
背景情况:
- 高强度间歇训练 (HIIT) 是有效的,但需要精确的强度控制.
- 百分比的三角形 (%Δ) 方法使用气体交换值和最大的氧气吸收 (V̇O2max) 来使相对运动强度正常化.
- 了解对%Δ-规定的HIIT反应的变化对于有效的训练至关重要.
研究的目的:
- 量化 HIIT 的性能,生理和感知反应的个体间和个体内变异性.
- 评估%Δ方法对HIIT的相对运动强度正常化的有效性.
- 为了确定日复一日的生物波动是否解释观察到的变异性.
主要方法:
- 重复措施,主体内设计与混合效果建模.
- 18名男性和4名女性骑自行车者完成了一项增量测试,以确定气体交换值和V̇O2max.
- 参与者进行了四次HIIT训练 (70%Δ,4分钟工作,2分钟休息) 以致疲劳,对反应的可变性进行了建模.
主要成果:
- 与个人内部水平 (11-50%) 相比,在个人间水平 (50-89%的总变异性) 观察到更大的变异性.
- 平均耗尽时间为20.3分钟,个体间标准偏差为9.3分钟 (46%CV),个体内标准偏差为4.5分钟 (22%CV).
- 性能,生理和感知反应显示出显著的个体间和个体内变化.
结论:
- %Δ方法由于高度可变性,在个人之间使详尽的HIIT相对强度正常化是无效的.
- 观察到的变异性远远大于日常生物波动或测量错误所能解释的.
- %Δ方法的局限性需要替代或调整的方法来准确的HIIT强度处方.

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...

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.
Purposes
Muscle Stimulation Frequency
Wave summation
At low firing rates, motor neurons induce individual twitch contractions in muscle fibers. These twitches...
Exercise and Cardiac Output
Sustained exercise increases the muscles' oxygen demand, which can be...
