Are Questionnaires on Respiratory Symptoms Reliable Predictors of Airway Hyperresponsiveness in Athletes and Sedentary Subjects?

This study aimed at determining the frequency of respiratory symptoms in high-level athletes and whether respiratory questionnaires are reliable predictors of airway hyperresponsiveness (AHR) in this population compared with control subjects.

Description
Summary:This study aimed at determining the frequency of respiratory symptoms in high-level athletes and whether respiratory questionnaires are reliable predictors of airway hyperresponsiveness (AHR) in this population compared with control subjects. One hundred high-level athletes exercising in different conditions of ambient air (dry, humid, cold or mixed dry and humid) and 50 sedentary control subjects answered four question sets on exercise-induced symptoms of postnasal drip (Q1), breathlessness, chest tightness and wheezing (Q2), and cough (Q3). Another question set (Q4) evaluated the self-description of nociceptive sensations associated with respiratory symptoms. Methacholine inhalation tests were performed in all subjects to obtain a 20% fall in forced expiratory volume in 1 second (PC20). AHR could be detected by questionnaires in 37 of 44 (84%) subjects with a PC20
