Large Indirect Calorimeter Rooms
Two of the four calorimeters rooms are large ~3mx4mx2.5m (30,000 liter volume) designed as livable quarters for studies that extend over multi-day periods.
Small Indirect Calorimeter Rooms
Two of the four calorimeters rooms are small ~2.5mx3mx2.5m (18,000 liter volume) designed for studies with young children and shorter time periods.
Infant Calorimeter
A smaller infant calorimeter (480 liters) is also available to measure sleeping energy expenditure in neonates through two years old.
Whole Room Indirect Calorimeters
Each calorimeter precisely measures the oxygen uptake (VO2)and carbon dioxide production (VCO2) of research subjects from childhood through adulthood, including pregnant and lactating women, in a controlled environmental chamber. The VO2 and VCO2 (in liters per minute) are measured in real time and are converted into kilocalories per minute to provide measurements in sleeping metabolic rate, basal metabolic rate, 24 hour total energy expenditure, and exercise energy expenditure (e.g. biking, walking, running, aerobics, or video game play). All research volunteers are closely monitored during the entire stay in the calorimeter whether short or long term. Heart rate, activity, body temperature, blood and urine collection are also available to be measured during any calorimeter study.
