Protocols

The Calorimetrics Chambers housed at Clermont-Ferrand have played a key role in the development of an array of research protocols, several of which are currently underway.
Below is a shortlist highlighting research focuses that have led to published papers:

• Study on energy expenditure in the elderly — ageing processes.
• Study on day-to-day variations in energy expenditure in elderly subjects over the course of a physical training programme.
• Study on daily energy expenditure in physically active versus inactive adolescents during different types of activity. Relationships identified between HR, EE and accelerometers.
• Study on whole-body and muscle lipid oxidation: influence of age and regular physical activity.
• Study on energy expenditure during sustained, long-haul physical activity, and patterns of energy expenditure change over a round-the-world bike ride.
• Study of the energy value of hydrogenated starch.
• Study on the oxidative metabolism of fatty acids in muscle tissue in elderly human according to physical activity levels.
• Study of energy balance, hydroelectrolytic balance, and fluid distribution in different body compartments during a simulated 4-day ultra-endurance challenge.
• Study of the net energy value of a starch product, and the effects on mineral absorption and the faecal excretion of cholesterol and bile salts in healthy human subjects.
• Study on patterns of change in energy expenditure in obese adolescents during a dieting-and-activity-based care programme at a paediatric healthcare clinic. Shift in HR-EE ratios.
• Oxidative metabolism of fatty acids in muscle tissue: effect of ageing and physical activity.
• Mechanisms driving weight-gain in Parkinson's patients following subthalamic deep-brain stimulation.

A grand total of 400 volunteers have completed one or more short or long-stay study programmes in the Clermont-Ferrand centre's Calorimetrics chambers.
This equates to over 600 in-chamber residencies, clocking up over 20,000 hours of calorimetrics records.
