PURPOSE The aim of this study was to determine the feasibility of generalist school teachers delivering curriculum connected high-intensity interval training in a school's physical education class time. METHOD Two schools volunteered to participate. A total of 84 students (11.9 [0.5] y, M = 64 and F = 19) volunteered to participate. Four classes from 2 schools were randomized to either intervention (n = 53) or control (n = 31) for one school term (8 wk). Intervention class teachers participated in a 1-day workshop instructing them how to deliver twice weekly, high-intensity interval training sessions. The control classes continued with their usual physical education curriculum. Recruitment, intervention fidelity, and program satisfaction were assessed. Preliminary efficacy (primary outcome cardiorespiratory fitness) was quantified using generalized linear mixed models, expressed as effect size. A range of secondary outcomes was also assessed. RESULTS The recruitment rate was 88%. About 84% of the sessions were delivered. The heart rate peak over all sessions was 89.6% (13%) of the predicted maximum. The intervention teachers reported high levels of satisfaction. Almost all student participants were positive about participating. No adverse events occurred. The adjusted between-group difference for cardiorespiratory fitness was trivial (effect size 0.02). CONCLUSIONS This teacher-delivered high-intensity interval training program was feasible and acceptable to both teachers and student participants. It is therefore potentially scalable.

将高强度间歇训练嵌入体育课的可行性和初步效果:一项集群随机对照试验。

目的 本研究的目的是确定通才学校教师在学校体育课时间提供课程相关的高强度间歇训练的可行性。方法 两所学校自愿参加。共有 84 名学生(11.9 [0.5] y,M = 64 和 F = 19)自愿参加。来自 2 所学校的 4 个班级被随机分配到干预组(n = 53)或控制组(n = 31),为期一个学期(8 周)。干预班教师参加了为期 1 天的研讨会,指导他们如何每周进行两次高强度间歇训练课程。控制班继续他们通常的体育课程。对招募、干预保真度和项目满意度进行了评估。使用广义线性混合模型量化初步疗效(主要结果心肺健康),表示为效应大小。还评估了一系列次要结果。结果 录用率为88%。大约 84% 的会话已交付。所有会话的心率峰值是预测最大值的 89.6% (13%)。干预教师报告了很高的满意度。几乎所有的学生参与者都对参与持积极态度。未发生不良事件。调整后的心肺健康组间差异微不足道(效应大小 0.02)。结论 这种由教师提供的高强度间歇训练计划是可行的,并且为教师和学生参与者所接受。因此,它具有潜在的可扩展性。还评估了一系列次要结果。结果 录用率为88%。大约 84% 的会话已交付。所有会话的心率峰值是预测最大值的 89.6% (13%)。干预教师报告了很高的满意度。几乎所有的学生参与者都对参与持积极态度。未发生不良事件。调整后的心肺健康组间差异微不足道(效应大小 0.02)。结论 这种由教师提供的高强度间歇训练计划是可行的,并且为教师和学生参与者所接受。因此,它具有潜在的可扩展性。还评估了一系列次要结果。结果 录用率为88%。大约 84% 的会话已交付。所有会话的心率峰值是预测最大值的 89.6% (13%)。干预教师报告了很高的满意度。几乎所有的学生参与者都对参与持积极态度。未发生不良事件。调整后的心肺健康组间差异微不足道(效应大小 0.02)。结论 这种由教师提供的高强度间歇训练计划是可行的,并且为教师和学生参与者所接受。因此,它具有潜在的可扩展性。干预教师报告了很高的满意度。几乎所有的学生参与者都对参与持积极态度。未发生不良事件。调整后的心肺健康组间差异微不足道(效应大小 0.02)。结论 这种由教师提供的高强度间歇训练计划是可行的,并且为教师和学生参与者所接受。因此,它具有潜在的可扩展性。干预教师报告了很高的满意度。几乎所有的学生参与者都对参与持积极态度。未发生不良事件。调整后的心肺健康组间差异微不足道(效应大小 0.02)。结论 这种由教师提供的高强度间歇训练计划是可行的,并且为教师和学生参与者所接受。因此,它具有潜在的可扩展性。
