摘要：Exercise-induced bronchospasm (EIB) is more often in some sports. Risk from EIB is higher in asthmatics, as in atopic patients. Pollens and environmental pollutants can also contribute to development of EIB. The aim of this study was to explore whether this challenge can result in changes in spirometry that would be positive for bronchospasm in competitors during orienteering event. The study was conducted during orienteering event in classic distances. Twenty-two competitors participated in the study (5 women, 17 men). Peak expiratory flow (PEF) was measured before the event and warming up, and during first minute after crossing the finish line. Each participant completed a specific symptom questionnaire. Only two competitors reported PEF fall significant for EIB (fall PEF>15% after the event). One of them had asthma during childhood, and other sometimes during competitions feels chest pain, wheezing or shortness of breath. None of competitors had asthma. Seven mentioned allergies in anamnesis. All participants were asked three questions for EIB prediction; one answered positive on first question, three on second, and all answered on third question were negative. The results showed that statistical difference between basal PEF and PEF after event was not significant (P<0.05). Physical activity during orienteering event didn’t have significant influence on bronchoreactivity. Further researches of EIB during orienteering are needed before definitive conclusions.
