目的新兴的文献表明，体育活动和健身可能对青少年的认知和心理健康产生积极影响。本研究的目的是评估两种高强度间歇训练（HIIT）方案对改善认知和心理健康结果的有效性（执行功能、心理健康、心理困扰和身体自我概念）。方法（n = 65;平均年龄= 15.8 ± 0.6岁）被随机分为三个条件：有氧运动计划（AEP; n = 21），阻力和有氧计划（RAP; n = 22），和控制（n = 22）。HIIT课程（每次8-10分钟）在体育课期间或午餐时间进行，每周三次，共8周。在基线和干预后立即进行评估，以检测执行功能（连线测试），心理健康，心理困扰和身体自我描述的变化，由对治疗分配不知情的研究人员进行。采用线性混合模型对干预效果进行了检验。科恩的d效应大小和临床推理也计算。结果虽然结果并不显着，执行功能的小改善，（平均变化（95% CI）-6.69（-22.03，8.64），d = -0.32）和心理健康（平均变化（95%CI）2.81（-2.06，7.68），d = 0.34）;以及执行功能的适度改善（平均变化（95% CI）-10.73（-26.22，4.76），d = -0.51），幸福感略有改善（平均变化（95%CI）2.96（-1.82，7.75），d = 0.36）和感觉外观（平均变化（95%CI）0.32（-0.25，0.86），d = 0.35）。平均感觉状态分数改善，从preworkout到postworkout在两个HIIT条件下，具有显着的结果为AEP（P = 0.001）。结论本研究强调了嵌入HIIT在学校的一天，改善青少年的认知和心理健康的潜力。
Purpose Emerging literature suggests that physical activity and fitness may have a positive effect on cognitive and mental health in adolescents. The purpose of the current study was to evaluate the efficacy of two high-intensity interval training (HIIT) protocols for improving cognitive and mental health outcomes (executive function, psychological well-being, psychological distress, and physical self-concept) in adolescents.Methods Participants (n = 65; mean age = 15.8 0.6 yr) were randomized to three conditions: aerobic exercise program (AEP; n = 21), resistance and aerobic program (RAP; n = 22), and control (n = 22). HIIT sessions (8-10 min per session) were delivered during physical education lessons or at lunchtime three times per week for 8 wk. Assessments were conducted at baseline and immediately postintervention to detect changes in executive function (trail making test), psychological well-being, psychological distress, and physical self-description by researchers blinded to treatment allocation. Intervention effects were examined using linear mixed models. Cohen's d effect sizes and clinical inference were also calculated.Results While results were not significant, small improvements in executive function (mean change (95% CI) -6.69 (-22.03, 8.64), d = -0.32) and psychological well-being (mean change (95% CI) 2.81 (-2.06, 7.68), d = 0.34) were evident in the AEP group; and moderate improvements in executive function (mean change (95% CI) -10.73 (-26.22, 4.76), d = -0.51), and small improvements in well-being (mean change (95% CI) 2.96 (-1.82, 7.75), d = 0.36) and perceived appearance (mean change (95% CI) 0.32 (-0.25, 0.86), d = 0.35), were observed for the RAP group. Mean feeling state scores improved from preworkout to postworkout in both HIIT conditions, with significant results for the AEP (P = 0.001).Conclusions This study highlights the potential of embedding HIIT within the school day for improving cognitive and mental health among adolescents.
