Research Project: Room Calorimeter Evaluation of Ambulatory Metabolic Monitoring System that Predicts Metabolic Fuel Use

Location: Food Components and Health Laboratory

Project Number: 8040-51530-011-17-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Jul 1, 2020
End Date: Jun 30, 2021

Objective:
The objectives of this research are to: 1) compare a portable respiratory gas monitoring system to observations made in a stationary room sized calorimeter, and 2) further develop a metabolic fuel model useful for identifying the relationship of various metabolic measure to whole body glucose regulation and subsequent body health outcomes.

Approach:
Calorimeter measurements will be made in the USDA Room Sized Calorimeter (RC) with simultaneously collected data from 1) a Continuous Glucose Monitor (CGM), 2) “Carbon dioxide/Oxygen Breath and Respiration Analyzer (COBRA)”, and 3) a “Real-Time Physiological Status Monitoring (RT-PSM) system named OBAN (Open Body Area Network). These data will be used to compare stationary and portable methodolgies. Real time metabolic data will be used for the further development of a metabolic fuel model useful for identifying the relationship of various metabolic measures to whole body glucose regulation and subsequent body health outcomes.
