The purpose of the current study was to develop and test a method for assessing the effect of outdoor activity context on level of physical activity in preschool children. The observational system for recording physical activity in children was used to define the test conditions and various levels of physical activity within a multielement design. In general, all participants were fairly sedentary during the analysis. The fixed playground equipment condition produced the most moderate-to-vigorous physical activity, a finding that does not correspond to the descriptive assessment literature on childhood physical activity.
本研究旨在开发和测试一种评估户外活动环境对学龄前儿童身体活动水平影响的方法。儿童身体活动观测系统用于定义测试条件和多元素设计中的各种身体活动水平。总的来说，在分析过程中，所有参与者都相当久坐。固定操场设备条件产生了最多的中等到剧烈的身体活动，这一发现与儿童身体活动的描述性评估文献不一致。
