Previous school-based high-intensity interval training (HIIT) interventions have focused on the quantity of physical activity (PA) achieved during physical education (PE) rather than students' PE experiences, including enjoyment. : To evaluate the feasibility of a fitness- and skill based HIIT intervention guided by the Self Determination Theory. : For this pretest-posttest randomized controlled 6-week pilot study, 4-5 grade students (15 boys, 30 girls; age = 10.5 ± 0.9 years) completed a 16-19-minute HIIT circuit (INT); whereas, 22 students (10 boys, 12 girls; age = 10.5 ± 0.9 years) engaged in regular PE (CON). Two-way mixed ANCOVA tests were performed to assess preliminary efficacy. : Participants reported favorable program satisfaction (mean 3.6 ± 1.5 out of 5). The physical educator reported a high feasibility survey score (31/35), and themes emerging from a program acceptability interview included positive perceptions of the HIIT program and strategies for future implementation. A large effect size was evident for cardiorespiratory fitness (ηp = 0.26), as VO increased in INT from 53.6 ± 6.1 to 56.9 ± 7.3 ml/kg/min and decreased in CON (53.9 ± 7.0 to 52.4 ± 10.4 ml/kg/min). Students in INT exhibited greater amounts of moderate-to-vigorous PA and vigorous PA during PE versus CON, based on accelerometer data (23.4 ± 5.0 vs. 15.7 ± 4.7 min/hr, ηp = 0.45; 4.5 ± 2.6 vs. 2.3 ± 1.3 min/hr; ηp = 0.27, respectively). : Findings support the feasibility of this fitness- and skill-based HIIT program and may be a valuable addition to elementary school PE programs.
先前基于学校的高强度间歇训练（HIIT）干预措施侧重于体育课（PE）期间实现的身体活动（PA）的数量，而不是学生的 PE 体验，包括享受。：评估由自我决定理论指导的基于健身和技能的 HIIT 干预的可行性。：在这项为期 6 周的预测试后随机对照试验中，4-5 年级学生（15 名男孩，30 名女孩；年龄= 10.5±0.9 岁）完成了 16-19 分钟的 HIIT 循环（INT）；而 22 名学生（10 名男孩，12 名女孩；年龄= 10.5±0.9 岁）则参加了常规的体育课（CON）。进行了双向混合方差分析检验以评估初步疗效。：参与者报告了对该项目的满意（平均值为 5 分制中的 3.6±1.5 分）。体育教师报告了较高的可行性调查评分（31/35），从项目可接受性访谈中出现的主题包括对 HIIT 项目的积极看法和未来实施的策略。心肺功能适应性的效果大小很大（ηp=0.26），因为 INT 中的 VO 从 53.6±6.1 增加到 56.9±7.3ml/kg/min，而 CON 则下降（53.9±7.0 到 52.4±10.4ml/kg/min）。基于加速度计数据，INT 中的学生在体育课上比 CON 中表现出更多的中等到剧烈的 PA 和剧烈的 PA（分别为 23.4±5.0 比 15.7±4.7min/hr，ηp=0.45；4.5±2.6 比 2.3±1.3min/hr，ηp=0.27）。：研究结果支持基于健身和技能的 HIIT 计划的可行性，可能是小学体育课的有价值补充。
