Exercise 6

Discuss how training increases VO₂ max.

Step 1 of 3

Maximal oxygen uptake or VO₂ max is the measure of the body’s capacity to use oxygen during exercise. The VO₂ max of an untrained person is relatively lower compared to a trained athlete. Several factors contribute to this increase in VO₂ max in trained individuals. The most important of these factors are cardiac output and a-O₂ difference (arteriovenous oxygen difference).
