| Summary: | <b>Background</b>: 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. <b>Methods</b>: 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. <b>Results</b>: The results revealed changes in physical well-being following the HIIT intervention (<i>p</i> = 0.01) compared to the control group (<i>p</i> = 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 (<i>p</i> = 0.04), 4 × 10 m agility test (<i>p</i> = 0.02), medicine ball throw test (<i>p</i> = 0.04), and sit-ups (30 s) (<i>p</i> = 0.01). <b>Conclusions</b>: This study highlights the effectiveness of school-based HIIT in significantly enhancing physical well-being and physical fitness among adolescents. |
