In general, athletes have trained to exhale quickly. (Oxygen loading only occurs during inspiration, and
expiration serves mainly to rid the body of carbon dioxide, so athletes train to actively expire quickly. Their
use of expiratory muscles assists in obtaining large measurements of FEV and MVV.) Due to the increased
resistance of airways in an asthmatic, their FEV and MVV measurements are reduced for the same level of
effort.
