Two very interesting studies. Thanks.
As previously described, nasal resistance to flow decreases with exercise, but it increases with cold inspired air. My questions are whether you controlled climatic conditions in your experiment and whether you have any data on the intra-nasal resistance in these subjects.
On another note, carrying on with Wilk's idea about psychological aspects, do you know which of your subjects were naiive to the notion of nasal breathing with exercise and which were knowledgable about it ?
Again, congratulations, Oded Bar-Or
