: The aim of this study is to investigate the effects of a school-based high-intensity interval training (HIIT) program on quality of life and physical fitness in adolescents. : The study included 60 male adolescents (16.2 ± 0.6 years), randomly assigned to one of two groups: the HIIT group (n = 30) and the control group (CG, n = 30). Participants completed the KIDSCREEN-27 questionnaire to evaluate quality of life and physical fitness tests, including vertical jump, repetitive strength, agility, and flexibility. The experimental program consisted of a 12-week intervention integrated into the warm-up phase of regular physical education (PE) classes. Each PE class lasted 45 min, with the HIIT regimen occupying 10 min of the warm-up phase. The HIIT sessions followed a Tabata-style structure, performed twice weekly. A two-way ANOVA with repeated measures assessed group and time interaction effects. : The results revealed changes in physical well-being following the HIIT intervention ( = 0.01) compared to the control group ( = 0.42). The results of the two-way ANOVA with repeated measures revealed interaction effects between group and time for the various fitness tests, countermovement jump ( = 0.04), 4 × 10 m agility test ( = 0.02), medicine ball throw test ( = 0.04), and sit-ups (30 s) ( = 0.01). : This study highlights the effectiveness of school-based HIIT in significantly enhancing physical well-being and physical fitness among adolescents.
本研究旨在调查一项基于学校的高强度间歇训练（HIIT）计划对青少年生活质量和身体素质的影响。该研究纳入了60名男性青少年（16.2±0.6岁），随机分为两组：HIIT组（n = 30）和对照组（CG，n = 30）。参与者完成了KIDSCREEN - 27问卷以评估生活质量，并进行了身体素质测试，包括垂直跳跃、重复力量、敏捷性和柔韧性。实验计划包括一个为期12周的干预，融入常规体育课的热身阶段。每节体育课持续45分钟，HIIT方案占热身阶段的10分钟。HIIT课程采用田畑式结构，每周进行两次。采用重复测量的双向方差分析评估组间和时间交互作用。结果显示，与对照组（P = 0.42）相比，HIIT干预后身体幸福感有变化（P = 0.01）。重复测量的双向方差分析结果显示，在各种体能测试中，组间和时间存在交互作用，包括反向移动跳跃（P = 0.04）、4×10米敏捷性测试（P = 0.02）、药球投掷测试（P = 0.04）和仰卧起坐（30秒）（P = 0.01）。本研究强调了基于学校的HIIT在显著提高青少年身体幸福感和身体素质方面的有效性。
