- Abstract
- Runners have increased numbers of neutrophils in the airways at rest and after
exercise compared with sedentary individuals. The aim of this study was to
determine whether Mediterranean seasonal changes in temperature, humidity or
airborne pollutants affect the airway cells of runners training outdoors in an
urban environment. In nine male amateur runners, cell composition, apoptosis, and
inflammatory mediators were measured in induced sputum collected at rest
(baseline) and the morning after races held in the fall (21 km), winter (12 km),
and summer (10 km). Concentrations of air pollutants were below the alert
threshold at all times. Neutrophil differential counts tended to increase after
all races (P = 0.055). Apoptosis of neutrophils increased with ozone (P < 0.005)
and particulate matter <10 microm (PM10) (P < 0.05) exposure. Bronchial
epithelial cell counts were low at all times and weakly correlated with ozone and
PM10 concentrations. Apoptotic bronchial epithelial cells increased after all
races (P < 0.05). Inflammatory mediators in induced sputum were low at baseline
and after the races, and correlated with neutrophil differential counts only at
rest. In conclusion, apoptosis of airway cells in runners appears to be affected
by both exercise and environmental conditions. Apoptosis of neutrophils increased
with exposure to environmental pollutants while apoptosis of bronchial epithelial
cells increased after intense exercise. Since no relationship was observed
between neutrophil counts and inflammatory mediators 20 h after races, airways
inflammation at this time point appears blunted in healthy runners and little
affected by exposure to mild seasonal changes and airborne pollutants. (literal)
