| Popis: | Aim: To objectively evaluate physical activity and energy expenditure in overweight and normal-weight 11-year-old children. Methods: The final sample consisted of 91 children (32 overweight and 59 normal-weight children), mean age (SD) = 11.3 (0.2) years. Energy expenditure and physical activity were assessed during two weekdays and two weekend days using a multiple- sensor body monitor (SenseWear Armband ; BodyMedia Inc., Pittsburgh, PA, USA). Time spent in physical activity was higher in normal-weight compared with overweight children (p = 0.002). The highest level of physical activity was noted in normal-weight boys [mean (SD) = 258 (114) min/day] and the lowest in overweight girls [mean (SD) = 136 (59) min/day] (p = 0.002). In contrast, energy expended during physical activity did not differ between normal-weight and overweight children (2.6 and 2.7 MJ/day, respectively, p = 0.89). The average decrease in physical activity at weekends was 39 min in overweight children (from 166 to 127 min/day) and 27 min in their normal-weight counterparts (from 230 to 203 min/day). Overweight children engaged in less physical activity of both moderate and vigorous intensity compared with their normal-weight peers. Both overweight and normal-weight children were less active at weekends than on weekdays. Initiatives aiming to increase physical activity of overweight children at weekends are warranted. |
