Exergaming has been considered a fun solution to promoting a physically active lifestyle. This study examined the impact of an exergaming-based program on urban children's physical activity participation, body composition and perceptions of the program.
A sample of 185 children's physical activity was measured in August 2009 (pretest), and percent body fat was used as index of body composition. Fourth graders were assigned to intervention group engaging in 30 minutes exergaming-based activities 3 times per week, while third and fifth graders were in comparison group. Measurements were repeated 9 months later (posttest). Interviews were conducted among 12 intervention children.
ANCOVA with repeated measures revealed a significant main effect for intervention, F(1, 179) = 10.69, P < .01. Specifically, intervention children had significantly greater increased physical activity levels than comparison children. Logistic regression for body composition indicated intervention children did not differ significantly in percent body fat change from comparison children, Chi square = 5.42, P = .14. Children interviewed reported positive attitudes toward the intervention.
The implementation of exergaming-based program could have a significantly positive effect on children's physical activity participation and attitudes. Meanwhile, long-term effect of the program on children's body composition deserves further investigation.
电子游戏健身被认为是促进积极生活方式的一种有趣方式。本研究探讨了基于电子游戏的项目对城市儿童身体活动参与度、身体成分以及对该项目认知的影响。
2009年8月对185名儿童的身体活动进行了测量(预测试),并将体脂百分比作为身体成分指标。四年级学生被分配到干预组,每周进行3次、每次30分钟的电子游戏健身活动,而三年级和五年级学生作为对照组。9个月后重复测量(后测试)。对12名干预组儿童进行了访谈。
重复测量的协方差分析显示干预有显著的主效应,F(1, 179) = 10.69,P <.01。具体而言,干预组儿童的身体活动水平显著高于对照组儿童。身体成分的逻辑回归表明,干预组儿童与对照组儿童在体脂百分比变化上没有显著差异,卡方 = 5.42,P =.14。接受访谈的儿童对干预持积极态度。
基于电子游戏的项目实施对儿童的身体活动参与度和态度有显著的积极影响。同时,该项目对儿童身体成分的长期影响值得进一步研究。
