Influence of Ambient Temperature on Resting Energy Expenditure in Metabolically Healthy Males and Females.

ABSTRACT:

Background

It is not yet clear to what extent the physiologic regulatory mechanisms that maintain core body temperature are reflected by changes in resting energy expenditure (REE). Particularly, in indirect calorimetry with a canopy, the effects of short-term temperature exposures have not yet been investigated. This can be of relevance for the determination of REE in practice.

Objectives

This randomized crossover study investigated the influence of a 30-min exposure to 18 °C (cool room temperature), 22 °C (room temperature), 28 °C (thermoneutral zone), and 38 °C (heat) on REE determined by assessing the inhaled oxygen volume and the exhaled carbon dioxide volume via indirect calorimetry on 4 consecutive days.

Methods

In total, 32 metabolically healthy participants [
