目标。一项随机对照试验研究，以检验增加学龄前儿童户外自由游戏时间可以增加他们日常身体活动水平的假设。方法。在一个低收入家庭的学前班就读的32名拉丁裔儿童（3.6 +/- 0.5岁），通过加速度计连续4个上学日对他们的身体活动进行了评估。经过两天的基线体力活动评估，参与者被随机分配到干预组（休会组，n = 17）或对照组（CON组，n = 15）。课间休息组每天额外获得两次30分钟的户外自由玩耍时间，持续两天。CON组遵循正常的上课时间表。采用Wilcoxon秩和检验检验组间体力活动变量的差异。结果。在平均每日总次数（CON, 48.2 +/- 114.5； RECESS, 58.2 +/- 74.6）和在校期间（CON, 64.6 +/- 181.9； RECESS, 59.7 +/- 79.1）每分钟计数，或每天总次数（CON, 0.4 +/- 1.3； RECESS, 0.3 +/- 0.8）和在校期间（CON, 0.6 +/- 2.1,- RECESS, 0.5 +/- 0.8）中至剧烈体育活动时间的变化方面，组间无统计学差异。结论。大量增加学龄前儿童的户外自由游戏时间并没有增加他们的身体活动水平。
Objective. A randomized controlled pilot study to test the hypothesis that increasing preschool children's outdoor free play time increases their daily physical activity levels. Methods. Physical activity was assessed by accelerometers for four consecutive school days in thirty-two Latino children (3.6 +/- 0.5 years) attending a preschool for low-income families. After two days of baseline physical activity assessment, participants were randomly assigned to an intervention (RECESS, n = 17) or control (CON; n = 15) group. The RECESS group received two additional 30-minute periods of outdoor free play time per day for two days. The CON group followed their normal classroom schedule. Between group differences in physical activity variables were tested with a Wilcoxon rank-sum test. Results. There were no statistically significant differences between groups in changes from baseline in average total daily (CON, 48.2 +/- 114.5; RECESS, 58.2 +/- 74.6) and during school day (CON, 64.6 +/- 181.9; RECESS, 59.7 +/- 79.1) counts per minute, or total daily (CON, 0.4 +/- 1.3; RECESS, 0.3 +/- 0.8) and during school day (CON, 0.6 +/- 2.1,- RECESS, 0.5 +/- 0.8) percent of time spent in moderate to vigorous physical activity. Conclusions. Substantially increasing preschoolers' outdoor free play time did not increase their physical activity levels.
