This study was constructed as a comparison group pre-test/post-test quasi-experiment to assess the effect of the implementation of the PE curriculum by specialist PE teachers on children's physical development and physical fitness.
146 classes from 66 Slovenian primary schools were assigned to quasi-test (71) and quasi-control (75) groups. Data from the SLOFIT database was used to compare the differences in physical fitness and development between groups of children whose PE lessons were delivered by specialist PE teachers from the second grade onwards (quasi-test, n = 950) or by generalist teachers in all first three grades (quasi-control, n = 994). The Linear Mixed Model was used to test the influence of specialist PE teachers' teaching.
The quasi-control group showed significantly lower improvement of physical fitness by -0.07 z-score units (95% CI -0.12 to 0.02) compared to the quasi-test group. A significant difference of -0.20 (-0.27 to -0.13) was observed in explosive strength, and of -0.15 (-0.23 to -0.08) in running speed, and in flexibility by -0.22 (-0.29 to -0.14). No significant differences in physical development were observed.
Specialist PE teachers were more successful than generalist teachers in achieving greater improvement of children's physical fitness, but no differences were observed in physical development of quasi-test and quasi-control group.
本研究构建了一个对照组前测/后测准实验，以评估由专业体育教师实施体育课程对儿童身体发育和身体素质的影响。
从 66 所斯洛文尼亚小学中抽取 146 个班级，分为准实验组（71 个班级）和准对照组（75 个班级）。使用 SLOFIT 数据库的数据，比较由专家体育教师从二年级开始教授体育课的儿童（准实验组，n = 950）与由普通教师在所有前三年教授体育课的儿童（准对照组，n = 994）的身体素质和发育差异。使用线性混合模型测试专家体育教师教学的影响。
与准实验组相比，准对照组的身体素质改善显著较低，为-0.07 个 z 分数单位（95%CI：-0.12 至 0.02）。在爆发力方面，差异显著，为-0.20（-0.27 至 -0.13）；在跑步速度方面，差异显著，为-0.15（-0.23 至 -0.08）；在灵活性方面，差异显著，为-0.22（-0.29 至 -0.14）。在身体发育方面未观察到显著差异。
专业体育教师比普通教师更成功地提高了儿童的身体素质，但在准实验组和准对照组的身体发育方面未观察到差异。
