A-VO2 Difference

Question 1

Define A-VO2 difference

Answer 1

difference in oxygen content between arteial and venous blood

Question 2

How do we calculate A-VO2 difference

Answer 2

Oxygen content in arterial blood - oxygen content in venous blood

Question 3

How do we achieve best performance considering A-VO2 difference?

Answer 3

-increase oxygen dissociation/extraction from blood into the muscle (Bohr Shift/aerobic respiration)
- increase A-VO2 difference
-increase endurance

Question 4

How can we increase A-VO2 difference?

Answer 4

-Continuous/HIIT training (forms of aerobic training) increases endurance
-increase temperature increases the tendency for oxygen to dissociate from haemoglobin (Bohr Shift)
-an effective warm up

Question 5

What does a high A-VO2 difference tell us about the diffusion gradient and aerobic capacity

Answer 5

Steep duffusion gradient
High aerobic capacity

Question 6

What type of athletes would aim to have a high A-VO2 difference

Answer 6

Long distance runners
Long distance bikers
Long distance swimmers
