Influence of Ambient Temperature on Resting Energy Expenditure of Healthy Adults

Not Applicable
Completed
Conditions
Resting Energy Expenditure
Registration Number
NCT05505240
Lead Sponsor
University of Bonn
Brief Summary

The aim of this study is to investigate the influence of four different ambient temperatures (18, 22, 28, 38°C) on the resting energy expenditure of healthy adults by respiratory gas analysis. It is assumed that the resting energy expenditure is higher at 18°C and 38°C than at the temperatures in between.

Detailed Description

In a crossover-design, 32 healthy men and women participate in four interventions. Each intervention includes a measurement of the resting energy expenditure by respiratory gas analysis at a different ambient temperature (18,22, 28 and 38°C). During this time body core- and surface temperature are assessed, as well as body composition via bioelectrical impedance analysis. For each participant the four individual study days take place in a randomized order on consecutive weekdays within a week.
