Bronchial hyperreactivity (BHR) may be present in rhinitis. The present study was aimed to compare airway responses in patients  with rhinitis symptoms alone following exercise challenge, and to  determine relationship of two different respiratory function tests. 98 subjects with rhinitis were investigated by spirometry and impulse oscillometry before and after exercise challenge. No  significant difference was detected  between spirometry and  impulse oscillometry measurements  before  and  after  exercise challenge in  subjects  with  rhinitis  alone.  No correlation between spirometry and impulse oscillometry indices was found in pre and post- exercise stages. We therefore conclude that exercise challenge is not an appropriate test to determine airway hyperresponsive in subjects with rhinitis symptoms alone and findings of spirometry and impulse oscillometry are not interrelated. https://ijaai.tums.ac.ir/index.php/ijaai/article/view/553 https://ijaai.tums.ac.ir/index.php/ijaai/article/download/553/490
