Exercise Tolerance Center (Pediatric)

Our mission is to enable children to comfortably play without respiratory distress at any level, from the playground to the competitive arena.


Our Services

The Pediatric Exercise Tolerance Center addresses an unmet need for the evaluation of exercise intolerance and treatment of exercise-related respiratory dysfunction in otherwise healthy children, in children with special needs and chronic illness, and in high performance athletes. National Jewish Health possesses the personnel needed to make comprehensive evaluations, a state-of-the-art exercise physiology lab, and on-site therapists to aid in treatment.

We are one of a few centers in the world that can readily perform continuous laryngoscopy during exercise, a procedure which enables the visualization of the upper airway during intense exercise. This test is used in the evaluation of exercise-induced laryngeal obstruction (aka vocal cord dysfunction). To date, we have performed the test over 500 times in patients ranging in age from 6-72.
