1.6 Starling's law Flashcards
1
Q
What is starlings law?
A
stroke volume increase in response to an increase in venous return
2
Q
what are the steps to starlings law?
A
increase in venous return
therefore greater diastolic filling of the heart
causes cardiac muscle to be stretched
resulting in more powerful contraction
and increased ejection fraction (stroke volume)
3
Q
What effect does starlings law have on sporting performance?
A
more oxygenated blood can be pumped to contracting muscles for aerobic respiration so runner able to run at sustained aerobic pace for longer (sustained high-intensity)
