Both, psychosocial stress and exercise in the past have been used as stressors to elevate saliva cortisol and change state anxiety levels. In the present study, high-school students at the age of 14 were randomly assigned to three experimental groups: (1) an exercise group (n = 18), that was running 15 minutes at a medium intensity level of 65-75% HRmax, (2) a psychosocial stress group (n = 19), and (3) a control group (n = 18). The psychosocial stress was induced to the students by completing a standardized intelligence test under the assumption that their IQ scores would be made public in class. Results display that only psychosocial stress but not exercise was able to significantly increase cortisol levels but decreased cognitive state anxiety in adolescents. The psychosocial stress protocol applied here is proposed for use in future stress studies with children or adolescents in group settings, e.g., in school.
过去，心理社会压力和运动都被用作应激源来提高唾液皮质醇水平并改变状态焦虑水平。在本研究中，14岁的高中生被随机分为三个实验组：（1）运动组（n = 18），以65 - 75% HRmax的中等强度水平跑步15分钟；（2）心理社会压力组（n = 19）；（3）对照组（n = 18）。通过让学生完成一项标准化智力测试来诱导心理社会压力，前提是他们的智商分数将在课堂上公布。结果显示，只有心理社会压力而非运动能够显著提高青少年的皮质醇水平，但降低认知状态焦虑。这里应用的心理社会压力方案建议在未来针对儿童或青少年的团体环境（如学校）压力研究中使用。
