概括

四组血流限制阻力练习 (BFR-RE) 的失败与75次重复计划的重复总数相匹配. 这种比较有助于理解BFR-RE协议中的机械等价性.

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
康复康复康复康复

背景情况:

低负荷阻力运动与血液流量限制 (BFR-RE) 通常使用任意肌肉衰竭或固定75重复方案.
之前的研究表明,这些方案之间的肌肉适应是可比的,但对匹配的运动量作用尚未完全理解.

研究的目的:

系统地审查和元分析四组低负荷BFR-RE到意志肌肉衰竭中执行的重复次数.
为了将这些体积与固定75重复方案 (例如,1x30,3x15) 进行比较.
为了确定两个协议是否产生相似的总和每组重复量.

主要方法:

10/31/2024 在PubMed和Scopus进行了系统的搜索,用于在BFR-RE中使用四组意志性肌肉衰竭的研究,负载≤50%的一次重复最大值 (1RM).
来自25项研究 (n=678) 的平均重复数据使用随机效应元分析进行了聚合.
一个样本的t测试比较每组和总体体积与参考75重复方案.

主要成果:

在四组中,执行到失败的重复总数平均为73.1 (95% CI: 61.1至85.2).
每组的平均重复分别为1至4组的36.0,14.7,11.5和10.4.
总体体积与固定75重复方案相似,但每组的分布有很大的差异.

结论:

四组BFR-RE到意志性肌肉衰竭导致总重复量与既定的75重复方案相似.
虽然总体量是匹配的,但在两个BFR-RE处方之间,重复的分布在各组之间有所不同.
这些发现为常用的BFR-RE协议的机械等价性提供了宝贵的见解.

Cardiac Output II: Effect of Stroke Volume on Cardiac Output

Cardiac Output II: Effect of Stroke Volume on Cardiac Output

Cardiac output (CO), the amount of blood the heart pumps per minute, is a parameter in cardiovascular physiology determined by stroke volume and heart rate. Stroke volume, the amount of blood pushed from one of the ventricles per heartbeat, is influenced by preload, afterload, and contractility.
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...

Exercise and Muscle Performance

Exercise and Muscle Performance

Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
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...

Regulation of Stroke Volume

Regulation of Stroke Volume

The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
