All children showed an early asthmatic reaction to exercise (range 14-62% fall in FEV1). In two children, a significant interaction (p < 0.05) was found between test day and clock time. However, the difference in FEV1 between exercise and control days for each clock time did not exceed the 99.6% confidence limits of normal diurnal variation in any of the children. We conclude that, in children with mild-to-moderate asthma, a LAR to exercise does not occur. This suggests that exercise is only a symptomatic trigger of asthma. Whether exercise is capable of inducing inflammation needs to be further investigated.
