概括

半程马拉松的业余训练重塑左心室 (LA) 并改善其功能,特别是在年轻女性中. 完成比赛可以减少LA体积,而不会影响右心房 (RA).

科学领域:

心脏病学心脏病学
运动医学运动医学
生理学生理学生理学

背景情况:

竞争性跑步在精英运动员中诱导心脏重塑和血液动力学变化.
有限的数据存在于半程马拉松后的业余跑步者的心房适应.
这项研究调查了半程马拉松训练和完成后休跑步者的心房变化.

研究的目的:

分析训练和21.0975公里跑步对左 (LA) 和右 (RA) 心房解剖和功能的心声学参数的影响.
为了评估LA和RA形态和功能在10周的训练期和半程马拉松比赛之前和之后的变化.

主要方法:

52名业余跑者 (平均年龄为32.96岁,32名男性) 接受了心声回声评估.
评估是在训练前,赛前和赛后进行的.
使用二维成像,多普勒和斑点追踪技术来评估形态和功能参数.

主要成果:

十周的训练增加了LA维度和体积 (p < 0.001) 和LA收缩性应变 (LASct) (p = 0.030),特别是在年轻女性中 (p = 0.029).
在训练期间,在RA形态或功能上没有观察到显著的变化.
完成半程马拉松导致LA体积减少,但没有影响RA形态或功能.

结论:

对于半程马拉松的业余训练会诱导左心房重塑,并增强活跃收缩功能,特别是在年轻女性中.
半程马拉松比赛本身减少了左心房的体积.
无论是训练还是比赛都没有显著地影响休跑步者的右心房形态或功能.

关键词:

业余跑步者业余跑步者在心房重塑.一半马拉松跑步跑步左心房应变是左心房应变.右心房张力右心房张力斑点跟踪回声心脏图谱 (echocardiography) 是一种跟踪斑点心脏图谱的方法.

Electrocardiogram

Electrocardiogram

An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.
Three major waveforms are present in a typical ECG recording: the P wave, the QRS complex, and...

Imaging Studies for Cardiovascular System I:Echocardiography

Imaging Studies for Cardiovascular System I:Echocardiography

Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...

Imaging Studies for Cardiovascular System II:Types of Echocardiography

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...
