Abstract
The objective of this study was to examine pre- and postexercise pulmonary function of males (13 children with asthma, 8 children without asthma) performing controlled exercise in 3 indoor sport environments: ice rink, gymnasium, and swimming pool. A positive test was defined as a 20% decrease in any of the forced expiratory values. Three children with asthma and 2 children without asthma had a greater than 20% decrease in FEV1 and FHVT following activity in the rink. One child with asthma had a greater than a 20% decrease in FEV1 following pool activity. In general, results showed children with asthma had a significant (p < .05) decrease in both FEV1 and FEVT% 5 min following exercise in the ice rink. No similar decrease was found 5 min following gymnasium and pool activity of the same intensity. In general, children without asthma maintained normal pulmonary function in all 3 environments. Evidence from this study would seem to suggest that the environmental conditions of the indoor ice rink may potentiate bronchospasm in some children with asthma.
