What this trial measures

  • Pulmonary Function: Lung VolumesChange from Baseline in differences between nonobese and obese children. Outcome measures will be assessed within 48-72 hours after completion of each study.

    Pulmonary function is comprised of several physiological variables but this study will primarily measure Lung Volume: FRC (liters) and TLC (liters)

  • Exercise Tolerance - Peak VO2Change from Baseline in differences between nonobese and obese children. Outcome measures will be assessed within 48-72 hours after completion of each study.

    Exercise Tolerances is represented by several physiological variables but the primary variable is Maximal oxygen uptake (L/min and percent predicted)

  • Dyspnea on ExertionChange from Baseline in differences between nonobese and obese children. Outcome measures will be assessed within 48-72 hours after completion of each study.

    Dyspnea on Exertion is represented using the Borg Scale which provides Ratings of Perceived Breathlessness (RPB) during constant load exercise cycling. The Borg Scale measures from 0-10, where 0 = no breathlessness and 10 = maximal breathlessness.
