Physical characteristics of the participants and energy expenditure (mean ± SD).

	Normal-weight (n = 19)	Overweight (n = 26)	p
Age (year)	10.5 ± 1.1	10.5 ± 1.0	0.84
Weight (kg)	39.1 ± 7.4	58.9 ± 11.3	<0.01
Height (m)	1.46 ± 0.10	1.49 ± 0.10	0.17
BMI (kg/m2)	18.3 ± 2.2	26.0 ± 2.5	<0.01
TEE (kJ/day)	8615 ± 1789	10,458 ± 1958	<0.01*
RMR (kJ/day)	5338 ± 813	6934 ± 1038	<0.01*
PAL	1.61 ± 0.26	1.51 ± 0.15	0.56*
PAEE (kJ/day)	2415 ± 1203	2588 ± 951	0.45*

Notes: RMR and TEE were assessed using the Douglas bag and doubly labeled water methods, respectively. PAL is calculated as TEE/RMR. PAEE is calculated as 0.9 × TEE − RMR.

Abbreviations: BMI = body mass index; PAEE = physical activity energy expenditure; PAL = physical activity level; RMR = resting metabolic rate; TEE = total energy expenditure.
