Sažetak
Physical activity is commonly prescribed as a rehabilitation treatment for asthma and allergic rhinitis (AR) although there are a high percentage of asthmatics with exercise-induced bronchospasm (EIB) and recent studies show beneficial effects of aerobic training on allergic inflammation. to test if the nose clip during the 6 minute free running test changes the magnitude of the EIB according to the severity of the AR. The study was conducted in 55 children with moderate persistent asthma and AR. Their asthma was controlled and they were daily participating in an aerobic fitness program. They were divided in two subgroups according to the median of intensity of their nasal symptoms (less nasal symptoms – LNS ; more nasal symptoms – MNS). The spirometry was performed before, 3’ and 20’ after 2 exercises (6 minutes free running with and without a nose clip) done a day apart. Subgroups were not significantly different according to their sensitization profile, asthma control, lung function and exhaled NO measurements and physical fitness. There was a significantly greater fall in FEV1 3’ after exercise with a nose clip in a LNS subgroup than in MNS subgroup and compared to testing without the nose clip. Contrary to the testing with the nose clip there were no significant differences in a FEV1 fall after exercise when the same patients were tested without the nose clip. It seems that regular mouth breathing due to nasal congestion somehow protects patients with asthma and AR from EIB.
