背景：步行上学与较高水平的身体活动相关，但上学途中本身对上学前身体活动的贡献尚不明确。
目的：本研究结合加速度计和全球定位系统（GPS）数据，以调查步行上学儿童身体活动的水平和位置。
方法：参与者是来自英国伦敦的137名儿童（年龄11.3±0.3岁），于2006年6月 - 7月进行测量。身体活动通过加速度计测量，位置通过GPS接收器确定。出行方式为自我报告。加速度计和GPS数据进行时间匹配，以便在两者都可用的情况下，为每10秒的时间段提供活动水平和位置。行程在地理信息系统（GIS）中绘制。
结果：步行上学的儿童上学前（上午8点到9点）每分钟的平均加速度计数比乘车上学的儿童高43%（878.8±387.6对608.7±264.1计数/分钟[cpm]，p（此处似乎内容不完整）
Background: Walking to school is associated with higher levels of physical activity, but the contribution of the journey itself to physical activity before school is unknown.Purpose: This study combined accelerometer and GPS data to investigate the level and location of physical activity in children walking to schoolMethods: Participants were 137 children (aged 11.3 +/- 0.3 years) from London, England, measured in June-July 2006 physical activity was measured by accelerometry, and location was determined with a GPS receiver Travel mode was self-reported Accelerometer and GPS data were time-matched to provide activity level and location for each 10-second epoch where both were available. Journeys were mapped in a GIS.Results: Mean accelerometer counts per minute before school (8:00AM to 9:00AM) were 43% higher in those who walked to school than those traveling by car (878.8 +/- 387.6 vs 608.7 +/- 264.1 counts per minute [cpm], p
