Room Calorimeter

Room Calorimeter

Includes two room calorimeters to measure human energy expenditure and substrate utilization for periods of up to 24 hrs or longer. A large chamber that includes a bed, toilet, sink, computer, TV and exercise equipment allowing a participant to live in the space for extended time periods (e.g. 24 -48 hrs). The smaller chamber has two purposes:

  1. to assess basal (resting) energy expenditure and substrate utilization,
  2. to assess short term (up to ~2 hrs) energy expenditure and substrate utilization during cycle ergometer exercise.

The large chamber, where participants will live in the space for generally 24-48 hrs will allow us the precise measurement of human energy metabolism (energy expenditure) to calibrate newly designed and commercially available wearable sensors designed to estimate energy expenditure. We will have the capability to translate sensor signals into energy expenditure by creating algorithms to process sensor signals into estimates of energy expenditure. In addition, the large calorimeter will be used in studies of human energy metabolism for projects in energy balance and weight management (e.g. metabolic responses to bariatric surgery), insulin resistance, muscle function and fatigue, aging, sleep quality, and cognition which leverages the expertise of faculty from nutrition, psychology, and kinesiology. The smaller resting metabolism chamber will allow us to:

  1. precisely determine the basal level of energy expenditure that is needed to obtain a comprehensive understanding of the individual components of total energy expenditure,
  2. assess energy expenditure and substrate utilization during short term exercise studies.
