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.
