(7 cards)
1
Q
what are 3 main factors regulating stroke volume
A
-preload
-afterload
-contractility
2
Q
what is the frank starling law
A
the more the heart stretches during preload, the more forcefully it will contract during pumping
3
Q
what is ejection factor
A
percent of blood the heart pumps out with each contraction
4
Q
what is the cardiac output equation
A
stroke volume x heart rate
5
Q
what is cardiovascular drift
A
heart rate slowly goes up during long exercise, even if you’re not working harder
6
Q
how do you determine intensity
A
-target heart rate
-karvonen formula
-borg scale of perceived exertion
7
Q
how to find target heart rate
A
(200-age)(% intensity)
