Cardio Vasuclar Drift, A-VO2 Difference/adaptions With Training

Question 1

What is cardiovascular drift

Answer 1

This is when your HR slowly climbs during steady state exercise.

Question 2

Why does cardiovascular drift occur

Answer 2

This is because as you exercise your stroke volume, and atrial pressure decreases due to you losing water in your blood through sweat.

This causes less plasma volume

Causes an increase in cardiac output

Causing a progressive rise in heart rate to cool body

Question 3

What is arterio venous difference

Answer 3

The difference in oxygen of the arterial blood arriving at the muscles and the venous blood leaving the muscles

Question 4

What is the arterial- venous difference at rest

Answer 4

There is not much difference as your muscles do not require that much oxygen

Question 5

What is the A -VO2 difference during exercise

Answer 5

It is high as your muscles need a lot of oxygen.
Training increases atrial venous difference as trained performers can extract more oxygen from their blood
