How Children Move: Activity Pattern Characteristics in Lean and Obese Chinese Children

Table 2

Activity pattern characteristics during school days and at the weekend in lean and obese Chinese children.

		Bouts per day	Mean duration of bouts (s)	Mean duration of between-bout intervals (s)	Mean peak intensity of bouts (RT3vmag.s^−1)
Lean (𝑛=42)	Weekday	961 ± 150	12.8 ± 1.6	23.7 ± 8.5	16.4 ± 2.1
Obese (𝑛=42)	Weekday	788 ± 220**	12.4 ± 1.5	38.5 ± 26.7**	15.2 ± 1.7*
Lean (𝑛=40)	Weekend	677 ± 218	13.7 ± 2.0	47.0 ± 32.2	16.4 ± 1.3
Obese (𝑛=39)	Weekend	483 ± 241**	14.5 ± 5.9	134.2 ± 167.8*	16.7 ± 4.9

Values are expressed as mean ± SD.
RT3 intensity cutoffs (RT3_vmag⋅s⁻¹): sedentary <7.0; low intensity ≥7.0 to <31.0; moderate intensity ≥31.0 to <68.5; vigorous intensity ≥68.5.
*significant difference between lean and obese, 𝑃<.01; **significant difference between lean and obese, 𝑃<.001.
