Participation in physical activity (PA) is fundamental to children's future health. Studies examining the temporal pattern of PA between weekdays and weekends in British preschool children are lacking. Therefore, the aim of this study was to compare PA levels between week and weekend days for UK preschool children, using objective measurements. One hundred and eighty-five preschool children (99 boys, 86 girls, aged 4-5 years), from central England wore a triaxial accelerometer (GENEActiv) for 4 days to determine PA. The time (min) and percentage (%) of time spent in light, moderate and vigorous PA (MVPA) was determined using specific cut-points for counts per minute related to 3-5 year olds. Of the sample, none of the children met the UK recommended 180 min or more of PA per day. A significant difference ( < 0.05) was observed between the amount of time that preschool children spent in sedentary behaviours on weekdays (91.9%) compared to weekend days (96.9%). During weekdays and weekend days, 6.3% and 2.0% of time was spent in MVPA, respectively. Therefore, a substantial proportion of British preschool children's day is spent in sedentary behaviours, with less MVPA accrued during the weekend. Regular engagement during the weekdays provides opportunities to accrue PA, which may not be present on weekend days.
参与体育活动对儿童未来的健康至关重要。目前缺乏对英国学龄前儿童工作日和周末体育活动时间模式的研究。因此，本研究的目的是通过客观测量来比较英国学龄前儿童工作日和周末的体育活动水平。来自英格兰中部的185名学龄前儿童（99名男孩，86名女孩，年龄4 - 5岁）佩戴三轴加速度计（GENEActiv）4天以确定体育活动情况。根据与3 - 5岁儿童每分钟计数相关的特定切点，确定了在轻度、中度和剧烈体育活动（MVPA）中花费的时间（分钟）和时间百分比（%）。在样本中，没有儿童达到英国建议的每天180分钟或更多的体育活动时间。观察到学龄前儿童在工作日久坐行为的时间量（91.9%）与周末（96.9%）之间存在显著差异（<0.05）。在工作日和周末，分别有6.3%和2.0%的时间用于MVPA。因此，英国学龄前儿童一天中的大部分时间都处于久坐行为，周末的MVPA较少。工作日的定期参与提供了积累体育活动的机会，而周末可能不存在这种机会。
