本研究的目的是评估一项旨在提高青少年体育课情感体验的干预措施的实施和近端影响。健康青少年（N= 74）被随机分配到基于情感或传统的运动处方。干预日志、观察和访谈记录了干预的实施情况。参与者在干预前后完成了一项30分钟的锻炼任务，其强度对他们来说是“良好的”。学习程序成功实施，学生享受学习参与。干预对体育运动期间的运动强度或“感觉良好”的运动任务没有影响。在对中等强度运动表现出消极情感反应的青少年中，在“感觉良好”任务中选择的强度随着时间的推移而增加。干预措施可能太弱，无法影响高质量的体育项目之外的行为。然而，研究结果确实表明，在经历了高质量的体育锻炼项目并结合心率监测后，不愿意锻炼的人可能会选择更高强度的锻炼。
The objective of this study was to evaluate the implementation and proximal impact of an intervention designed to enhance adolescents' affective experience during Physical Education (PE). Healthy adolescents (N= 74) were randomly assigned to an affect-based or a traditional exercise prescription. Intervention logs, observations and interviews documented the implementation of the intervention. Participants completed a 30-min exercise task at an intensity that felt "good" to them before and after the intervention. Study procedures were implemented successfully and students enjoyed study participation. The intervention had no impact on exercise intensity during PE or during the "feels-good" exercise task. Among adolescents who manifested a negative affective response to moderate-intensity exercise at baseline, the selected intensity during the "feels-good" task increased over time. The intervention may have been too weak to impact behavior over and above a high-quality PE program. The results do suggest, however, that reluctant exercisers may choose to exercise at a higher intensity after experiencing a high-quality PE program in combination with heart rate monitoring.
