After aerobic training, the contractility of left ventricles is increased. Therefore, the stroke volume is increased.

有氧训练能增加左心室之收缩能力, 因此能增加心缩排血量.

It may also be sensed in healthy persons during exercise when stroke volume or rate increases.

健康人在运动时也可感觉心悸,因为这时的每搏量和心率才有增加.

Diminished venous return ( preload ) results in decreased ventricular filling and reduced stroke volume.

静脉回流减少 ( 前负荷 ) 导致心室充盈下降和每搏量减少.
