Despite well-documented evidence that physical activity is beneficial to children, average fitness levels of US children have declined. Lack of physical activity has been associated with childhood obesity. We evaluated the effects of a physical activity program in the elementary school classroom on health outcomes.
Three schools in the Independence School District in Independence, Missouri, were assigned to receive the ABC (Activity Bursts in the Classroom) for Fitness program, and 2 comparable schools served as controls. The program, led by classroom teachers, provides multiple, brief, structured physical activity breaks throughout the day. Baseline data for the study were collected in September 2007, and follow-up data were collected in April 2008.
Physical fitness measures of upper-body strength, abdominal strength, and trunk extensor improved (P <.001). Medication use for asthma (P = .03), attention-deficit hyperactivity disorder (P = .07), or either medication combined (P = .005) decreased.
The effects of the program on daily physical activity, fitness, and measures of health are beneficial.
尽管有大量文献证明身体活动有益于儿童，但美国儿童的平均健康水平却在下降。缺乏身体活动与儿童肥胖有关。我们评估了在小学课堂上开展身体活动计划对健康结果的影响。
密苏里州独立学区的 3 所学校被分配到接受 ABC（课堂活动爆发）健身计划，而 2 所可比学校作为对照组。该计划由课堂教师领导，全天提供多次短暂的结构化身体活动休息。该研究的基线数据于 2007 年 9 月收集，随访数据于 2008 年 4 月收集。
上半身力量、腹部力量和躯干伸展力量等身体健身指标均有所改善（P<0.001）。哮喘（P=0.03）、注意缺陷多动障碍（P=0.07）或两者同时用药（P=0.005）的用药减少。
该计划对日常身体活动、健身和健康指标的影响是有益的。
