WebJul 6, 2016 · This increased stroke volume can be observed as a lower resting heart rate as well as a lower training heart rate. Perfectly logical, right? To pump the same amount of blood, your heart needs fewer beats because the volume per beat has increased.

WebChanges in ventricular preload dramatically affect ventricular stroke volume by what is called the Frank-Starling mechanism. Increased preload increases stroke volume, whereas decreased preload decreases stroke volume by altering the force of contraction of the cardiac muscle. The concept of preload can be applied to either the ventricles or atria.
