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.
本研究旨在评估一项旨在增强青少年在体育课中情感体验的干预措施的实施情况及其近期影响。健康青少年（N=74）被随机分配到基于情感的干预组或传统运动处方组。干预日志、观察和访谈记录了干预措施的实施情况。参与者在干预前后完成了 30 分钟的运动任务，强度让他们感觉“良好”。研究程序成功实施，学生也乐于参与研究。该干预措施对体育课或“感觉良好”的运动任务中的运动强度没有影响。在基线时对中等强度运动表现出消极情感反应的青少年中，“感觉良好”任务中的选择强度随时间增加。该干预措施可能过于微弱，无法在高质量的体育课计划之外影响行为。然而，结果确实表明，在经历了高质量的体育课计划和心率监测后，不情愿的锻炼者可能会选择以更高的强度进行锻炼。
