To evaluate the effects of a comprehensive physical activity (PA) promotion programme in elementary schools on children's total PA levels, leisure-time PA, physical fitness and psychosocial correlates of PA.
A pre-test-post-test design over two school years.
Sixteen elementary schools (764 children, mean age: 11.2 +/- 0.7 years) were randomly assigned to the intervention condition (n = 8) and the control condition (n = 8). The intervention included a health-related physical education programme, an extracurricular PA promotion programme and classroom-based PA education lessons. In the total sample, leisure-time PA, psychosocial correlates of PA and physical fitness were measured using a PA questionnaire and the Eurofit test battery. In a sub-sample, total PA levels were measured using an accelerometer.
According to accelerometer data, children's moderate PA and moderate-to-vigorous PA (MVPA) levels decreased less in the intervention schools than in the control schools (P < 0.01). The average time spent on MVPA decreased by 9 min per day in the intervention schools compared with 33 min per day in the control schools. Children in the intervention schools reported significantly more moderate PA in leisure time than the controls (P < 0.05). No overall improvement of physical fitness and no effects on the psychosocial correlates of PA were found.
The comprehensive PA promotion programme was successful in preventing a decline in children's total activity levels. Furthermore, the intervention increased children's PA engagement in leisure time. Therefore, implementation needs to be encouraged.
评估小学综合体育活动（PA）促进项目对儿童总PA水平、休闲时间PA、身体素质以及PA的心理社会相关因素的影响。
为期两个学年的前后测设计。
16所小学（764名儿童，平均年龄：11.2±0.7岁）被随机分为干预组（n = 8）和对照组（n = 8）。干预措施包括与健康相关的体育教育项目、课外PA促进项目以及基于课堂的PA教育课程。在总样本中，使用PA问卷和欧洲体适能测试套件测量休闲时间PA、PA的心理社会相关因素和身体素质。在一个子样本中，使用加速度计测量总PA水平。
根据加速度计数据，干预学校儿童的中度PA和中度至剧烈PA（MVPA）水平下降幅度小于对照学校（P < 0.01）。干预学校每天MVPA的平均时间减少9分钟，而对照学校为每天33分钟。干预学校的儿童报告说，他们在休闲时间的中度PA明显多于对照组（P < 0.05）。未发现身体素质有整体改善，也未发现对PA的心理社会相关因素有影响。
综合PA促进项目成功地防止了儿童总活动水平的下降。此外，干预增加了儿童在休闲时间的PA参与度。因此，需要鼓励实施该项目。
