Body Composition Related Evaluation of Airway Tone and Hyper-rEactivity Using Oscillometry

Purpose

This study will determine if airway resistance to airflow and pressure, measured by Oscillometry, is associated with abnormal findings on methacholine challenge testing and whether these findings are associated with body habitus,
