Primaire uitkomstmaten
Main objective of this study is the measurement of pulmonary function (change in FEV1, FEV0.5 and FEF50) during and post-exercise in young children with asthmatic features. Thus the percent change in pulmonary function (FEV1, FEV0.5 and FEF50) during and post-exercise.

Onderzoeksproduct en/of interventie
No intervention, other than the exercise provocation challenge, will be investigated. An exercise provocation challenge is part of the routine clinical evaluation of patients with exercise induced symptoms or asthma. However, an exercise provocation challenge in the evaluation of asthmatic children aged 5 till 7 years isn’t widely used and can therefore be seen as an intervention. Moreover, our newly designed exercise provocation challenge, using a jumping castle is experimental.
Thus the intervention used in our study is a newly designed exercise provocation challenge.
This exercise provocation challenge exists of jumping on a jumping castle for at least 4 minutes (target is a 6 minute lasting exercise at 80% of the predicted maximum heart rate). Before, during and after exercise, patients perform pulmonary function measurements (flow volume curves).
