Inclusion Criteria: * no history of smoking, no history or evidence of heart disease, no history of uncontrolled hypertension, no documented and/or diagnosed sleep disorders, no diagnosed diabetes, no metabolic disorders, no history of significant mental illness, no dietary restrictions, no serious health conditions, or no musculoskeletal abnormality that would preclude exercise. * Normal weight children with a body mass index between the 16th and 84th percentile * Obese children with a body mass index \> 95th percentile but less than 170% above the 95th percentile and less than an absolute body mass index of 40 kg·m2 * Pulmonary function criteria 1) forced vital capacity ≥ 80% predicted, 2) forced expiratory volume in the first second (FEV1) ≥ 75% predicted, and total lung capacity ≥ 80% predicted Exclusion Criteria: * Children with significant diseases other than obesity and mild asthma will be excluded. A significant disease is defined as either a disease that in the opinion of the PI or medical consultant Dr. Craig Nakamura may put the participant at risk because of participation in the study or a disease that may influence the results of the study or the patient's ability to participate in the study. * Children who cannot follow directions (e.g., eating before testing), adequately perform procedures (e.g., pulmonary function tests), or keep appointments (e.g., no shows for testing), will be excluded from study participation. * Because the risk of severe exercise induc…
