Abstract

We investigated if 12 min of high-intensity exercise performed within a regular school break lead to an increase in cortisol levels in primary school students. 53 students of a 4th grade (9-10 years of age) were randomly assigned to an experimental (EG) and a control group (CG). Saliva collection took place after a normal school lesson (pre-test) and after 12 min of intensive exercise in a defined heart rate (HR) interval (EG, n=32) and control condition (movie watching) (CG, n=21), respectively (post-test). Saliva was analyzed for cortisol. We observed a significant group by test interaction indicating a different pre-to-post-test development for EG as compared to CG. The interaction effect, however, was caused by an attenuated cortisol concentration in the control group. We argue that the control condition, in which the students watched a joyful movie, acted as a distractor, which led to a reduction of general school stress.

摘要

我们研究了在学校课间休息期间进行 12 分钟的高强度运动是否会导致小学生的皮质醇水平升高。将 4 年级的 53 名学生（9-10 岁）随机分配到实验组（EG）和对照组（CG）。分别在正常的学校课程后（前测）和在特定的心率（HR）区间内进行 12 分钟的剧烈运动（EG，n=32）和对照条件（观看电影）（CG，n=21）后（后测）采集唾液样本。对唾液中的皮质醇进行分析。我们观察到组间测试的交互作用显著，表明与 CG 相比，EG 的前后测试发展情况不同。然而，这种交互作用是由对照组皮质醇浓度降低引起的。我们认为，学生观看愉快的电影的对照条件起到了分散注意力的作用，从而减轻了一般的学校压力。
