Heart rate and stroke volume response to exercise Flashcards
1
Q
what is heart rate
A
sub max, increases as exercise increases and decreases as intensity decreases
2
Q
what is the stroke volume response to exercise
A
when you start running it increases gradually and reaches a plateau at 120ml-140ml per beat
3
Q
what is the stroke volume response to exercise because of
A
venous recture and ventricles ability to stretch further and enlarge
4
Q
what is venour recture
A
increases in blood returning to heart
5
Q
what is the cardiac output response to exercise
A
co increases directly in line with exercise intensity from 5000ml / min up to 20,000 to 40,000 / min max in highly trained endurance athletes
6
Q
what does cardiac output increases to supply
A
increased demand for oxygen from our working muscles
