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 (RT3vmag · 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.
