| Abstract: | Introduction. – Long-term effort and resistance in athletes are often associated with symptoms and signs of airway inflammation. The use of induced sputum is a convenient method of assessing airway inflammatory cells. In this study we investigate the effect of endurance exercise on total and differential airway cell counts.Synthesis. – Instead the absence of post-exercise respiratory symptoms or spirometric changes, airway cell counts change significantly: runners showed increased neutrophil and lymphocyte differential count (P < 0,01).Conclusion. – Physical exertion, particularly when prolonged, causes significant stress to the respiratory system. Associated hyperventilation and airway exposure to contaminants of inhaled air could explain cellular changes. |
