This study aims to investigate the combining effects of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) compared to MICT alone on physical fitness, academic performance, and anxiety levels among adolescents in a school setting.
Sixty male adolescents were randomly assigned to either an experimental group (HIIT + MICT) or a control group (MICT only) for 12 weeks. Physical fitness was assessed using lung capacity, a 50-meter sprint, a standing long jump, and a 1000-meter run. Anxiety levels were measured using the Zung Self-Rating Anxiety Scale, and cognitive performance through academic evaluations. Statistical analyses included Shapiro-Wilk, Mann-Whitney U, unpaired t-tests, chi-square, and McNemar tests.
After 12 weeks, the experimental group showed a significant increase in lung capacity (10.30 ml/kg) compared to the control group (3.18 ml/kg, P = 0.03). Sprint and run completion times were also significantly faster in the experimental group (P < 0.01 and P = 0.02), with greater improvements in the long jump (P = 0.01). Academic performance and anxiety levels improved significantly in the experimental group (P = 0.02 and P < 0.01), while the control group exhibited no significant changes.
This study demonstrated that combining HIIT with MICT results in greater improvements in adolescent cardiorespiratory fitness, anaerobic performance, academic outcomes, and anxiety levels compared to MICT alone. These findings support the incorporation of HIIT alongside traditional MICT in adolescents.
The study was retrospectively registered in the clinical trials registry on 26/04/2023 (ChiCTR2300070895).
本研究旨在探讨在学校环境中，与单独进行中等强度持续训练（MICT）相比，高强度间歇训练（HIIT）与中等强度持续训练相结合对青少年身体素质、学业成绩和焦虑水平的综合影响。
60名男性青少年被随机分为实验组（HIIT + MICT）或对照组（仅MICT），为期12周。使用肺活量、50米短跑、立定跳远和1000米跑评估身体素质。使用zung自评焦虑量表测量焦虑水平，并通过学业评估测量认知表现。统计分析包括Shapiro-Wilk检验、Mann-Whitney U检验、非配对t检验、卡方检验和McNemar检验。
12周后，与对照组（3.18毫升/千克，P = 0.03）相比，实验组的肺活量显著增加（10.30毫升/千克）。实验组的短跑和跑步完成时间也显著更快（P < 0.01和P = 0.02），跳远成绩有更大改善（P = 0.01）。实验组的学业成绩和焦虑水平显著改善（P = 0.02和P < 0.01），而对照组没有显著变化。
本研究表明，与单独进行MICT相比，将HIIT与MICT相结合能使青少年的心肺功能、无氧运动能力、学业成绩和焦虑水平得到更大改善。这些发现支持在青少年中同时采用HIIT和传统的MICT。
该研究于2023年4月26日在临床试验注册中心进行回顾性注册（ChiCTR2300070895）。
