BACKGROUND
This study examined the effects of a 4-week technology-enhanced physical activity (PA) interventions on students’ real-time daily PA and aerobic fitness levels.
METHODS
116 fifth-graders were assigned to one intervention group ( = 31) participating in daily physical activity engaging the brain with Fitbit Challenge (PAEB-C), another intervention group ( = 29) wearing Fitbits only (Fitbit-O) daily, five days per week, or the comparison group ( = 56). Four-week real-time PA data were collected from the intervention students via Fitbase. Three groups were pre- and post-tested aerobic fitness.
RESULTS
The PAEB-C students showed significantly higher steps and minutes of being very active and fairly active ( = 7.999, = 0.014, = 0.121; = 5.667, = 0.021, = 0.089; = 10.572, = 0.002, = 0.154) and lower minutes of being sedentary daily ( = 4.639, = 0.035, = 0.074) than the Fitbit-O group. Both Fitbit groups exhibited significantly greater increases in aerobic fitness scores than the comparison group over time ( = 21.946, = 0.001, = 0.303). Boys were more physically active and fit than girls.
CONCLUSIONS
Technology-enhanced PA intervention was effective for improving real-time PA and aerobic fitness.
背景
本研究探讨了为期4周的技术增强型体育活动（PA）干预对学生实时日常体育活动和有氧适能水平的影响。
方法
116名五年级学生被分为一个干预组（n = 31），参与通过Fitbit挑战让大脑参与的日常体育活动（PAEB - C）；另一个干预组（n = 29），每周五天每天仅佩戴Fitbit（Fitbit - O）；以及对照组（n = 56）。通过Fitbase从干预组学生中收集了为期4周的实时体育活动数据。对三组进行了有氧适能的前后测试。
结果
与Fitbit - O组相比，PAEB - C组学生的步数、非常活跃和较为活跃的分钟数显著更高（F = 7.999，p = 0.014，η² = 0.121；F = 5.667，p = 0.021，η² = 0.089；F = 10.572，p = 0.002，η² = 0.154），而每日久坐分钟数更低（F = 4.639，p = 0.035，η² = 0.074）。随着时间的推移，两个Fitbit组的有氧适能得分增幅均显著高于对照组（F = 21.946，p = 0.001，η² = 0.303）。男孩比女孩身体更活跃且更健康。
结论
技术增强型体育活动干预对于改善实时体育活动和有氧适能是有效的。
