Key Clinical Message Laryngoscopy is the gold standard to diagnose exercise‐induced laryngeal obstruction, though inspiratory flow‐volume loop may provide a clue. We combined tidal flow‐volume loop analysis plus laryngoscopy during exercise and found that cigar‐shaped – not flattened – inspiratory loops are associated with obstruction. Pursed‐lip breathing slows inhalation thereby reducing vocal fold adduction.
