Many studies have been conducted on the effects of ambient
(outdoor) air pollution exposure on cardiovascular fitness among
both adults and schoolchildren. One study, for example, found
children in higher pollution areas had lower VO2 max than those
in lower pollution areas (Yu et al., 2004). The study also suggested
if the students engaged in regular physical exercise in a highly
polluted environment, then there were few to no beneficial effects
on cardiopulmonary fitness. The majority of studies on the effects
of environmental pollutants on respiratory health have focused on using lung function measurements such as forced vital capacity,
forced expiratory volume, and peak flow rates, not VO2 max for
cardiovascular fitness as a measure of the predictive effect of
chemicals among exposed subjects.
