目前还不清楚，导致青少年足球运动员高水平有氧运动的潜在心血管机制是什么。该研究的目的是评估一组青春期前足球运动员在增量运动测试期间的整体和区域收缩和舒张功能标记。来自两个职业足球俱乐部的 22 名男性足球运动员 (SP)（年龄：12.0 +/- 0.3 岁）自愿参加了这项研究。还招募了 15 名年龄相近（年龄：11.7 +/- 0.2 岁）的休闲活跃男孩（CON）。所有男孩都接受了自行车测力计测试直至力竭。使用M型超声心动图确定心脏尺寸。在次最大和最大运动期间，使用连续波多普勒超声技术来得出每搏输出量（SVIndex）。组织多普勒成像用于量化休息时以及次最大和最大运动强度时的收缩功能（S'adj）和舒张功能（E；E'adj 和 E/E'）。使用斑点追踪超声心动图来确定次最大运动强度下的峰值纵向ε。 SP 表现显着（P
It is unclear, what the underlying cardiovascular mechanisms are that give rise to the high level of aerobic fitness seen in youth soccer players. The aim of the study was to evaluate global and regional markers of systolic and diastolic function in a group of pre-adolescent soccer players during an incremental exercise test. Twenty-two, male soccer players (SP) from two professional soccer clubs (age: 12.0 +/- 0.3 years) volunteered for the study. Fifteen recreationally active boys (CON), of similar age (age: 11.7 +/- 0.2 years) were also recruited. All boys underwent a cycle ergometer test to exhaustion. Cardiac dimensions were determined using M-mode echocardiography. During submaximal and maximal exercise, continuous-wave Doppler ultrasound techniques were used to derive stroke volume (SVIndex). Tissue-Doppler imaging was used to quantify systolic (S'adj) and diastolic function (E; E'adj and E/E') at rest and both submaximal and maximal exercise intensities. Speckle tracking echocardiography was used to determine peak longitudinal epsilon at submaximal exercise intensities. SP demonstrated significantly (P
