Data expressed as mean ± standard deviation.
♀: females; ♂: males; BM: body mass; BMI: Body Mass Index; FFM: fat-free mass; FM: fat mass; RMR: resting metabolic rate; TEE: total energy expenditure; PAEE: Physical activity energy expenditure; PAL: physical activity level (TEE/RMR); VM CPM: vector magnitude counts per minute per day.
*Significant differences by sex (T-Student test, p-value < 0.05).
†Significant difference with the total sample (T-Student test, p-value < 0.05).
#Three females were excluded for Steps/d and VM CPM due to accelerometry criteria for valid days.
