Exercise 5

Understand the contribution of heart rate, stroke volume, and the a-v O₂ difference in determining VO₂ max.

Step 1 of 3

The maximal oxygen uptake (VO₂ max) is the rate at which vital organs like muscles consume oxygen during exercise. It is expressed as ml oxygen/kg body mass/min. The various factors that determine the VO₂ max are as follows:

• Systemic blood flow

• Systemic oxygen extraction
