NCT00798564

Brief Summary

The overall aim is to explore pathophysiological factors related to airway hyperresponsiveness to direct and indirect provocation stimuli in athletes with different sport activities, with special focus on epithelial reaction linked to CC16 and to eicosanoid related inflammatory response. The investigators also wish to compare indirect testing done as hyper osmotic challenge with Mannitol compared to a defined sport specific exercise challenge.
