  1. Data expressed as mean ± standard deviation.
  2. ♀: 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.
  3. *Significant differences by sex (T-Student test, p-value < 0.05).
  4. †Significant difference with the total sample (T-Student test, p-value < 0.05).
  5. #Three females were excluded for Steps/d and VM CPM due to accelerometry criteria for valid days.
