1
Q
short term effects of exercise on the cardiovascular system?
A
- increased heart rate
- increased stroke volume
- increased cardiac output
2
Q
heart rate
A
number of beats per minute
3
Q
stroke volume
A
the amount of blood pumped out of the left ventricle per beat
4
Q
Untrained at rest
A
heart rate - 72bpm
stroke volume - 60ml
cardiac output - 4.3l/min
5
Q
trained at rest
A
heart rate - 50bpm
stroke volume - 86ml
cardiac output - 4.3l/min
6
Q
submaximal exercise
A
any exercise that doesn’t succeed 85% maximum heart rate
7
Q
maximal exercise
A
any exercise that goes over 85% maximum heart rate
8

what’s anticipatory rise?
A
increase in heart rate is caused by an increase in activity of the sympathetic nervous system causing the adrenal glands to release adrenaline into the blood stream.
