Question

differentiate between absolute and relative VO2?

Answer 1

Ans:-

concept :- absolute VO2 --- doesn't depend on mass and size of organism.

relative VO2 depends upon mass and size of organism.

absolute VO2 reflects the total (absolute) amount of oxygen consumed by a body, regardless of size, age or gender .

But relative VO2 indicates that score corrected to some reference, which happens to be a unit of mass or one kilogram (1 kg.). The units of measurement are all metric:

• Absolute VO2 = Liters per min (L/min)
• Relative VO2 = milliliters per minute per kilogram (a unit of mass)

For eg if Emma absolute VO2 is 5 lit / min. And her weight is 100 kgs.

Then relative VO2 of Emma is 50 ml / kg / min.

Relative VO2 is more imp for finding different datas related to metabolic rate of body.
