Physical activity (PA) in school physical education (PE) is a signature component of health promotion and health education. The study's aim was to explore PA levels and sedentary time in German elementary school PE lessons and relate them to selected personal and environmental PA determinants. Accelerometer measurements were collected from 328 students (47% male, mean age 8.7 ± 1.2 years) in 11 elementary schools in Baden-Wuerttemberg (Germany). PA levels and sedentary time were analyzed regarding gender, grade, body mass index, selected correlates of active living and health behaviors, as well as the PE teachers' PE education status. In line with previous research, the analyses of PA levels and sedentary time confirm gender and grade differences and highlight older girls as the less active group. Deviant weight status and parents' PA levels were found to be important determinants for PA levels and sedentary time of girls and offer starting points for intervention studies as well as gender-appropriate PE in elementary schools. Specialist PE teacher status proved to be a negative determinant of PA levels and sedentary time for boys and girls and should be investigated in further studies, especially regarding the didactic and methodological background.
学校体育教育（PE）中的身体活动（PA）是健康促进和健康教育的一个标志性组成部分。该研究的目的是探讨德国小学体育课中的身体活动水平和久坐时间，并将它们与选定的个人和环境身体活动决定因素联系起来。从德国巴登-符腾堡州11所小学的328名学生（47%为男性，平均年龄8.7±1.2岁）中收集了加速度计测量数据。对身体活动水平和久坐时间进行了分析，涉及性别、年级、体重指数、积极生活和健康行为的选定相关因素，以及体育教师的体育教育状况。与先前的研究一致，对身体活动水平和久坐时间的分析证实了性别和年级差异，并突出显示年龄较大的女孩是活动较少的群体。发现体重状况异常和父母的身体活动水平是女孩身体活动水平和久坐时间的重要决定因素，为干预研究以及小学阶段适合性别的体育教育提供了切入点。事实证明，专业体育教师身份是男孩和女孩身体活动水平和久坐时间的一个负面决定因素，应在进一步研究中进行调查，特别是关于教学和方法背景方面。
