This study aimed at evaluating the effect of the "Walk," an 8-month physical activity (PA) program led by classroom and physical education teachers, on the motor competence (MC) and PA of 5- to 6-year-old children.
A total of 143 children (mean age = 61.51 [1.85] mo) participated in the study and were randomly assigned to the experimental and control groups. Children's MC was assessed by the Körperkoordination Test für Kinder (KTK), and PA was objectively measured by Omron HJ-720IT-E2 pedometers. Measurements were performed at baseline, midintervention, and postintervention. A 1-sample t test computed at baseline step counts revealed that children presented significantly lower PA than recommended for their age (P < .001). To examine the effect of the intervention on children's MC and PA, several repeated-measures analyses of variance were utilized on (1) KTK item scores and (2) pedometer data.
The results revealed that the Walk project led to practically significant changes in the experimental group compared with the control group in both MC (P < .001, η > .14 for all KTK items) and PA (P < .001, η = .23).
This study highlights the efficacy of a PA project, involving both classroom and physical education teachers, for the enhancement of children's MC and PA.
本研究旨在评估“Walk”项目对 5 至 6 岁儿童运动能力(MC)和身体活动(PA)的影响。该项目为期 8 个月,由课堂和体育教师主导。
共有 143 名儿童(平均年龄 61.51 [1.85] 个月)参与了研究,并被随机分配到实验组和对照组。儿童的 MC 通过 Körperkoordination Test für Kinder(KTK)进行评估,PA 通过欧姆龙 HJ-720IT-E2 计步器进行客观测量。在基线、中期干预和后期干预时进行测量。基线步数的 1 样本 t 检验显示,儿童的 PA 明显低于其年龄推荐值(P <.001)。为了检验干预对儿童 MC 和 PA 的影响,我们对 KTK 项目得分和计步器数据进行了多次重复测量方差分析。
结果显示,与对照组相比,实验组在 MC(P <.001,所有 KTK 项目的η >.14)和 PA(P <.001,η =.23)方面均发生了具有实际意义的变化。
本研究强调了一个涉及课堂和体育教师的 PA 项目对提高儿童 MC 和 PA 的有效性。
