MONTAURIER Christophe

Engineer, Manager of the Technical Platform "Indirect Calorimetry", and developer of computer applications.

 

The technical platform is a common resource that includes facilities located on two sites:

 

* 2 Calorimetric Chambers of 10 m² located in Clermont Ferrand at CRNH d'Auvergne. They allow calculations of energy expenditure and human RQ continuously over long periods of time, based on measurements of respiratory exchanges (Indirect Calorimetry), in the following areas:

    - accurate calculation of the energy balance over 24h from the monitoring of inputs and expenses

    - determination of the kinetics of energy expenditure

    - evaluation of the nutritional needs of a specific population (eg athletes)

    - determination of metabolic disturbances

    - study of the thermogenic properties of nutrients, medicines and nutritional formulas (diets)

    - Exploration of energy expenditure under usual conditions of life

The calorimetric chambers allow to accurately estimate the energy expenditure and the use of energy substrates (proteins, lipids, carbohydrates) of an individual living under conditions allowing precise control of his physical activity and diet.

 

* 4 Calorimetric cages for rats or mice located at the UNH animal facility at the INRA site in Theix. The principle of measuring the energy expenditure of rats and mice is here also based on indirect calorimetry.

 

The management of these facilities and the exploitation of the data generated require the development of specific programs, particularly in VBA and Matlab.
