High-intensity interval training (HIIT) is an effective strategy for improving a variety of health outcomes within the school setting. However, there is limited research on the implementation of school-based HIIT interventions and the integration of HIIT within the Health and Physical Education (HPE) curriculum. The aims of the Making a HIIT study are to: 1) describe the methodology and evaluate the feasibility of co-designing HIIT workouts with students and teachers in HPE; 2) determine the effect of co-designed HIIT workouts on cardiorespiratory and muscular fitness, and executive function; 3) understand the effect of co-design on students' motivation, enjoyment, and self-efficacy towards the workouts; and 4) evaluate the implementation of the intervention.
Three schools will participate. Within each school, three different groups will be formed from Year 7 and 8 classes: 1) Co-Designers; 2) HIIT Only; and 3) Control. The study will include two phases. In phase one, Group 1 will co-design HIIT workouts as part of the HPE curriculum using an iterative process with the researcher, teacher, and students as collaborators. This process will be evaluated using student discussions, student surveys, and teacher interviews. In phase two, Groups 1 and 2 will use the co-designed 10-minute HIIT workouts in HPE for 8-weeks. Group 3 (control) will continue their regular HPE lessons. All students will participate in cardiorespiratory fitness, muscular fitness, and executive function assessments before and after the HIIT program or control period. Students will complete questionnaires on their motivation, enjoyment, and self-efficacy of the workouts. Differences between groups will be assessed using linear regressions to account for covariates. Heart rate and rating of perceived exertion will be collected during each HIIT session. The implementation will be evaluated using the Framework for Effective Implementation. Ethical approval was granted by the University of Queensland Human Research Ethics Committee and other relevant bodies.
This study will be the first to co-design HIIT workouts with teachers and students within the HPE curriculum. As this study relies on co-design, each HIIT workout will differ, which will add variability between HIIT workouts but increase the ecological validity of the study.

高强度间歇训练（HIIT）是在学校环境中改善各种健康结果的有效策略。然而，关于基于学校的 HIIT 干预措施的实施以及将 HIIT 融入健康和体育教育（HPE）课程的研究有限。“制作 HIIT”研究的目的是：1）描述与 HPE 中的学生和教师共同设计 HIIT 锻炼的方法，并评估其可行性；2）确定共同设计的 HIIT 锻炼对心肺和肌肉健康以及执行功能的影响；3）了解共同设计对学生对锻炼的动机、享受和自我效能的影响；4）评估干预措施的实施情况。
将有 3 所学校参与。在每所学校中，将从 7 年级和 8 年级的班级中组成 3 个不同的小组：1）共同设计者；2）仅 HIIT；3）对照组。该研究将包括两个阶段。在第一阶段，第 1 组将与研究人员、教师和学生一起，通过迭代过程共同设计 HIIT 锻炼，作为 HPE 课程的一部分。将使用学生讨论、学生调查和教师访谈来评估此过程。在第二阶段，第 1 组和第 2 组将在 HPE 中使用共同设计的 10 分钟 HIIT 锻炼 8 周。第 3 组（对照组）将继续进行常规的 HPE 课程。所有学生将在 HIIT 计划或对照期之前和之后参加心肺功能、肌肉力量和执行功能评估。学生将完成关于他们对锻炼的动机、享受和自我效能的问卷。将使用线性回归来评估组间差异，以考虑协变量。在每次 HIIT 期间，将收集心率和感知用力程度。将使用有效的实施框架来评估实施情况。昆士兰大学人类研究伦理委员会和其他相关机构已批准该研究的伦理。
这将是首次在 HPE 课程中与教师和学生共同设计 HIIT 锻炼。由于本研究依赖于共同设计，因此每个 HIIT 锻炼都会有所不同，这将增加 HIIT 锻炼之间的变异性，但会增加研究的生态有效性。
