Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this study is to quantify energy metabolism using indirect calorimetry at rest, in the presence of excess energy following a meal, and in response to the demand for energy during exercise. The investigators also will examine the individual and joint associations of activity and obesity status on neurocognitive domains of appetite control. Participants will include adolescent males and females (N=80) using a 2 x 2 cross-sectional study design, stratified by body weight (normal vs overweight/obese) and physical activity level (sedentary vs. active).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The investigators hypothesize that low levels of fitness and MVPA result in impaired metabolic function in adolescents. For this pilot study, the investigators will quantify variations in metabolic characteristics using a 2 x 2 cross-sectional study design, stratified by body weight (normal vs overweight/obese) and physical activity (sedentary vs. active). The goal is to identify metabolic factors that influence the energy balance system to directly inform interventions designed to prevent or reduce the prevalence of pediatric obesity.
