目的。研究课后 NutriActive 计划对幼儿的人体测量、运动技能和健康水平的影响。设计。在这项准实验研究中，在为期 4 周的干预后以及暑假（4 个月）后，对干预学生和对照组学生的人体测量、运动技能和体能测量进行了比较。环境。两所干预小学和两所控制微城市小学。科目。 42 名干预儿童和 28 名对照幼儿园和一年级学生（50% 是男孩，82% 是白人）。干涉。为期 4 周的计划包括每天早上散步和课后体育活动课程，重点是运动技能发展、营养/健康课程、零食和非结构化主动游戏。措施。体重指数、腰围以及健身和运动技能水平。分析。方差、t 检验和逐步回归的重复测量分析。结果。 4 周时，干预组在一些体能测试和所有运动技能测试中得分明显更高。体能和技能水平的提高从 30% 到 270% 不等。 4 个月时，各组之间的差异有所缩小，但仍然显着，干预组在某些测试中得分更高。 4 个月时，技能水平成为心血管健康的预测指标。在任何时间点，各组之间的人体测量结果都没有差异。结论。短期、密集的课外活动可以显着、可持续地提高幼儿的运动技能和健身水平。
Purpose. To examine the effects of an after-school NutriActive program on anthropometric measurements, motor skills, and fitness levels of young children. Design. In this quasi-experimental study, anthropometric, motor skill, and fitness measurements were compared between intervention and control students at baseline, following a 4-week intervention, and after a summer break (4 months). Setting. Two intervention and two control microurban elementary schools. Subjects. Forty-two intervention and 28 control kindergarten and first-grade students (50% boys, 82% Caucasian). Intervention. A 4-week program consisted daily of a morning walk and an after-school physical activity lesson with an emphasis on motor skill development, nutrition/health lesson, snack, and nonstructured active play. Measures. Body mass index, waist circumference, and fitness and motor skill levels. Analysis. Repeated-measures analysis of variance, t-test, and stepwise regression. Results. The intervention group scored significantly better on some fitness and all motor skill tests at 4 weeks. The improvements in fitness and skill levels ranged from 30% to 270%. At 4 months, differences between the groups diminished but remained significant, with better scores for the intervention group on some tests. Skill levels emerged as predictors of cardiovascular fitness at 4 months. Anthropometric measurements did not differ between the groups at any time point. Conclusion. A short, intense after-school program can produce significant, sustainable improvements in motor skill and fitness levels of young children.
