To use a predominately objective measurement approach to assess and describe: (1) the amount of time that children aged 10-13 years spend participating in outdoor active play, active travel, curriculum-based physical activity at school, and organized sport; (2) the movement intensity composition of these four types of physical activity (i.e., % of time spent at a sedentary, light, or moderate-to-vigorous intensity); and (3) the proportion of each movement intensity obtained by participating in these four types of physical activity.
Three hundred seventy-seven children aged 10-13 years from Kingston, Canada, were studied. Children wore an accelerometer and GPS watch for 7 days and recorded the start and end times of the school day, recess periods, and organized sport sessions on a log. These data were used to estimate time spent in the four types of physical activity and the movement intensity composition of these activities.
Time spent in outdoor active play (36 min/day) and organized sport (40 min/day) was higher than that for active travel (17 min/day) and curriculum-based physical activity (26 min/day). With the exception of organized sport, values were higher for boys than for girls. Older children accumulated less outdoor active play and more active travel than younger children. The greatest proportion of light- and moderate-to-vigorous-intensity movement was attributed to outdoor active play.
We used a primarily objective measurement approach to assess and describe the amount of time children aged 10-13 participate in four types of physical activity. These descriptive findings could be used to identify target areas for physical activity interventions and policies.
使用主要的客观测量方法来评估和描述：（1）10-13 岁儿童参与户外活动、积极出行、学校课程相关体育活动和组织运动的时间量；（2）这四种体育活动的运动强度组成（即，处于久坐、低强度、中高强度的时间比例）；以及（3）通过参与这四种体育活动获得的每种运动强度的比例。
对来自加拿大金斯顿的 377 名 10-13 岁儿童进行了研究。儿童佩戴加速度计和 GPS 手表 7 天，并在日志上记录上学日、课间休息和组织运动课程的开始和结束时间。这些数据用于估计四种体育活动的时间和这些活动的运动强度组成。
户外活动（36 分钟/天）和组织运动（40 分钟/天）的时间高于积极出行（17 分钟/天）和课程相关体育活动（26 分钟/天）。除了组织运动，男孩的时间高于女孩。年龄较大的儿童比年龄较小的儿童进行的户外活动较少，积极出行较多。中高强度运动的最大比例归因于户外活动。
我们使用主要的客观测量方法来评估和描述 10-13 岁儿童参与四种类型体育活动的时间量。这些描述性发现可用于确定体育活动干预和政策的目标领域。
