High-intensity interval training (HIIT) in school settings has been much less studied in adolescents. The aim of this study was to examine the impact of HIIT on health-related fitness in adolescents.
The total sample consisted of 60 adolescents (age 16.33 ± 0.62 years) from secondary Grammar school, randomly divided into two groups: the experimental (EG) (30) and the control group (CG) (30). The experimental program (12-weeks; 2 times per week) involved two Tabata sessions during one physical education class lasting 4 min each. Participants were tested for health-related fitness components-cardiorespiratory fitness (The Shuttle Run Test (SRT) and strength, hand grip test, standing long jump (SLJ) and counter movement jump (CMJ).
Both the EG and the CG experienced significant positive changes in SRT (meters) and VO values compared to baseline value ( < 0.05), however, the increase in the EG was significantly higher than that in the CG (SRT - η = 0.111; VO - η = 0.111, < 0.01). The EG showed significant improvement in SRT (meters) and VO values compared to the CG ( < 0.01). Regarding the hand grip test results, a significant time × group interaction was found only for right hand ( < 0.01). Moreover, the improvements in SLJ and CMJ values was greater in EG than that in the CG group (SLJ- η = 0.182; CMJ- η = 0.112, < 0.01).
Findings indicate that HIIT implemented into physical education classes can result in significant improvements in selected health related fitness components in adolescents.
在学校环境中，针对青少年的高强度间歇训练（HIIT）研究较少。本研究旨在探讨HIIT对青少年健康相关体能的影响。
样本总量为60名来自文法中学的青少年（年龄16.33±0.62岁），随机分为两组：实验组（EG）（30人）和对照组（CG）（30人）。实验方案（为期12周；每周两次）包括在一节体育课中进行两次塔巴塔训练，每次持续4分钟。对参与者进行与健康相关的体能成分测试——心肺适能（穿梭跑测试（SRT））、力量（手握力测试）、立定跳远（SLJ）和纵跳（CMJ）。
与基线值相比，EG组和CG组的SRT（米）和VO值均有显著正向变化（P<0.05），然而，EG组的增加幅度显著高于CG组（SRT - η² = 0.111；VO - η² = 0.111，P<0.01）。与CG组相比，EG组的SRT（米）和VO值有显著改善（P<0.01）。关于手握力测试结果，仅在右手发现了显著的时间×组间交互作用（P<0.01）。此外，EG组的SLJ和CMJ值的改善幅度大于CG组（SLJ - η² = 0.182；CMJ - η² = 0.112，P<0.01）。
研究结果表明，在体育课中实施HIIT可使青少年某些与健康相关的体能成分得到显著改善。
