39 3- to 5-year-old children wore heart-rate monitors for 12 hr. on three consecutive days to examine physical activity patterns. Parent logs supplied additional information on type and location of activity. The highest number of accumulated minutes of moderate to vigorous physical activity was recorded during the weekday (38.6 min.) and weekend (31.4 min.) afternoons, a time period when more activity occurred outdoors. Sustained activity was mostly short in duration, but many children (71%) accumulated recommended amounts of activity on the weekday, fewer (46%) on the weekend. Spearman rank correlations for weekday (r=.50, p=.004) and weekend (r=.58, p=.004) activity were significant. Considering health risk factors associated with physical inactivity, early educators must look to the essence of young children's physical activity patterns in designing programs. Large motor activity that is intense and that occurs outdoors is a good place to start.
39名3至5岁的儿童连续三天佩戴心率监测器12小时，以检查身体活动模式。家长日志提供了有关活动类型和地点的额外信息。中度至剧烈身体活动累计分钟数最多的记录出现在工作日（38.6分钟）和周末（31.4分钟）的下午，这是户外活动较多的时间段。持续活动大多持续时间较短，但许多儿童（71%）在工作日积累了建议的活动量，在周末积累的儿童较少（46%）。工作日（r = 0.50，p = 0.004）和周末（r = 0.58，p = 0.004）活动的斯皮尔曼等级相关性显著。考虑到与缺乏身体活动相关的健康风险因素，早期教育工作者在设计项目时必须关注幼儿身体活动模式的本质。在户外进行的高强度大肌肉活动是一个很好的起点。
