Short term effects of exercise (cardiovascular)
- Cardiovascular
- Cardiac Output (Q) = SV x HR
- SV - Every time the heart beats,, blood is pumped out
- Ventricles contract with a higher force
- S.A Node
- 40-50% of blood is pumped out
- Heart Rate increases
- Adrenaline is released
- Trained athlete = Rest: SV (105ml/beat), HR = 60 BPM...
- Trained athlete = Maximum: SV (190mll/beat), HR = 192 BPM
- Increase in blood pressure
- Systolic value and diastolic value (120/80)
- Systolic = pressure in the artery, when your heart is beating.
- Diastolic value = pressure in the artery between beats
- Exercise tends to affect the systolic value more than the disatolic
- Blood redirects throught the vascular shunt
- 20% of your blood to muscles at rest
- Vasoconstriction
- Vasodilations
- 84% of your blood to the muscles when exercising
- Blood volume
- Goes down (10%)
