了解孩子如何以及在何处积累他们的体育锻炼（PA）和久坐的几分钟对行为干预具有重要意义。
这项研究的目的是检查临时PA和久坐时间（SED）在前儿童中和远离学校的持续时间和强度。
在上学期间检查了21名7-11岁儿童（57％的女孩； 57％的非白人； 24％的超重/肥胖）。 （学校内和校外）和非学校通过加速度计。
在上学期间将上学时间与非学校时间进行比较时，儿童在学校内的较高比例的灯光下降[49.3％（即5分钟18秒），而39.6％（即3小时53分钟），p = 0.01 ]。与校外相比[30分钟的不间断SED 52.4％（即11个孩子）比85.7％（即18个孩子），p = 0.02]。
这些发现表明，在学校时，儿童是最活跃的，最不久坐的，但在这种环境下，儿童仅积累了大约18分钟的中度到vig虫的PA。
这些初步发现可以帮助告知旨在促进儿童终身体育锻炼行为的体育活动节目。
Understanding how and where children accumulate their physical activity (PA) and sedentary minutes throughout the day has important implications for behavioral interventions. The purpose of this study was to examine the duration and intensity of habitual PA and sedentary time (SED) at and away from school among preadolescent children. Data from twenty-one children ages 7–11 (57% girls; 57% non-white; 24% overweight/obese) were included in this analysis. Proportion of time spent in PA, SED, and SED bouts were examined on school days (in-school and out-of-school) and non-school days via accelerometry. When comparing school time with non-school time on school days, children accumulated a higher proportion of light PA while in-school [49.3% (i.e. 5 minutes 18 seconds) vs. 39.6% (i.e. 3 hours 53 minutes), p=0.01]. While at school, the proportion of time spent in SED was less [46.3% (i.e. 3 hours 7 minutes) vs. 56.3% (i.e. 5 hours 32 minutes), p=0.01] and fewer children spent time engaged in prolonged sitting compared to out-of-school [uninterrupted SED for 30 minutes 52.4% (i.e. 11 children) vs. 85.7% (i.e. 18 children), p=0.02]. These findings suggest children are proportionately most active and least sedentary when at school, yet children only accumulated approximately 18 minutes of moderate-to-vigorous PA in this environment. These preliminary findings can help to inform physical activity programming designed to promote life-long physical activity behaviors in children.
