Although high-intensity interval training (HIIT) is perceived to be an efficient way to meet health outcomes in physical education (PE), the effect of HIIT on the learning environment of students is unknown. Purpose: This study compared two PE interventions lasting 8 weeks and assessed the potential efficacy of embedding HIIT into a PE program to meet concurrent health and educative outcomes. Methods: Participants (N = 166; mean age = 12.91 years) were assigned to one of two study conditions according to intact groupings: HIIT program (n = 84) and dynamic PE (DPE) program (n = 82). Assessments occurred at baseline and postintervention. A repeated-measures analysis of variance was used to test the intervention effects in each group. Results: Postintervention analysis demonstrated increases in health indices of both groups and comparing the effect size of each intervention revealed no difference. Systematic direct observation revealed effects for the provision of terminal feedback within the HIIT intervention (g = 1.03) when compared with the DPE intervention. A self-report questionnaire revealed changes in motivation toward PE among students allocated to the HIIT group were trivial, whereas students exposed to the DPE program displayed increased levels of motivation toward their PE experience. Conclusions: This study demonstrates that HIIT may elicit positive changes in PE settings by creating a “time potential” leading to an increased opportunity to learn without negating health gains. The DPE program proved to be move favorable in terms of student motivations to learn during PE.

高强度间歇训练与健康优化体育：在中等体育教育中实现健康和教育成果——一项非随机对照试验

尽管高强度间歇训练 (HIIT) 被认为是实现体育教育 (PE) 健康成果的有效方式，但 HIIT 对学生学习环境的影响尚不清楚。目的：本研究比较了两种持续 8 周的 PE 干预措施，并评估了将 HIIT 嵌入 PE 计划以同时满足健康和教育结果的潜在功效。方法：参与者（N = 166；平均年龄 = 12.91 岁）根据完整分组被分配到两种研究条件之一：HIIT 计划（n = 84）和动态 PE (DPE) 计划（n = 82）。评估发生在基线和干预后。重复测量方差分析用于检验各组的干预效果。结果：干预后分析表明两组的健康指数都有所增加，比较每种干预措施的效果大小没有发现差异。与 DPE 干预相比，系统直接观察揭示了在 HIIT 干预中提供终端反馈的效果 (g = 1.03)。一份自我报告问卷显示，分配到 HIIT 组的学生体育动机的变化微不足道，而接触 DPE 项目的学生表现出对体育体验的动机水平提高。结论：这项研究表明，HIIT 可以通过创造“时间潜力”，在不影响健康的情况下增加学习机会，从而引发体育环境的积极变化。事实证明，就学生在体育期间学习的动机而言，DPE 计划是有利的。
