AEEActi, AEE obtained by means of the Actiheart; AEEIDEEA, AEE obtained by means of the Intelligent Device for Energy Expenditure and Physical Activity (IDEEA); AEERT3, AEE obtained by means of the RT3; AEEref, total energy expenditure measured using the doubly labelled water method during days 1–15 minus BMR measured using indirect calorimetry; AEE5dresult, total energy expenditure, measured using the doubly labelled water method during days 1–5 minus BMR measured using indirect calorimetry.
* Mean value was significantly different from that for AEEref (P < 0·001).
† Mean value was significantly different from that for AEE5dresult (P < 0·001).
