Q

What happens to Inspiratory Reserve volume during vigorous exercise?

Q

What happens to expiratory reserve volume during vigorous exercise?

A

Expiratory reserve volume (ERV) will decrease but less than the inspiratory reserve volume. Although it is beneficial to blow out more air by using some of the ERV in order to remove as much carbon dioxide as possible, it takes significantly more muscle contraction to consume ERV compared to IRV.
