/Objective: This study aimed to compare the effects of two combined training methods on health-related physical fitness components in adolescents.
Seventy-six adolescents (16.1 ± 1.1 years, n = 44 female) were randomized into groups of moderate-intensity continuous training combined with resistance training (MICT + RT), high-intensity interval training combined with resistance training (HIIT + RT), or Control. The training sessions were performed twice weekly for 12 weeks. The health-related physical fitness components evaluated were: body composition, muscular and cardiorespiratory fitness.
The intervention groups had a significant reduction in body fat percentage and improvement in abdominal repetitions and VO after 12 weeks of combined exercise program (p < 0.001). Intervention effects were found to significantly reduce body fat percentage for the MICT + RT and HIIT + RT groups compared to the control group (mean difference: -3.8; 95% CI: -6.2; -1 0.3; mean difference: -4.7; 95%CI: -7.1; -2.3, respectively). For muscle fitness, significant effects of the intervention were found in increasing the number of abdominal repetitions favoring the MICT + RT group compared to the control group (mean difference: 9.5; 95% CI: 4.4; 14.7) and HIIT + RT compared to the control group (mean difference: 14.1; 95% CI 9; 19.3). For cardiorespiratory fitness, significant effects of the intervention on improving VO were found in the experimental groups (MICT + RT vs Control group: mean difference: 4.4; 95% CI: 2.2; 6.6; and HIIT + RT vs. Control group: mean difference: 5.5, 95% CI: 3.3; 7.7).
The results suggest that 12 weeks of training using MCIT + RT or HIIT + RT showed a similar effect for health-related physical fitness components in adolescents.
/目的：本研究旨在比较两种联合训练方法对青少年健康相关身体素质成分的影响。
76名青少年（16.1±1.1岁，44名女性）被随机分为中等强度持续训练联合阻力训练组（MICT+RT）、高强度间歇训练联合阻力训练组（HIIT+RT）或对照组。训练课程每周进行两次，共12周。评估的健康相关身体素质成分包括：身体成分、肌肉和心肺功能。
经过12周的联合运动计划后，干预组的体脂百分比显著降低，腹部重复次数和VO有所改善（p<0.001）。与对照组相比，发现MICT+RT组和HIIT+RT组的干预效果显著降低了体脂百分比（平均差异：-3.8；95%置信区间：-6.2；-10.3；平均差异：-4.7；95%置信区间：-7.1；-2.3）。对于肌肉功能，与对照组相比，干预对增加腹部重复次数有显著影响，有利于MICT+RT组（平均差异：9.5；95%置信区间：4.4；14.7）和HIIT+RT组与对照组相比（平均差异：14.1；95%置信区间9；19.3）。对于心肺功能，实验组干预对改善VO有显著影响（MICT+RT组与对照组：平均差异：4.4；95%置信区间：2.2；6.6；HIIT+RT组与对照组：平均差异：5.5，95%置信区间：3.3；7.7）。
结果表明，使用MCIT+RT或HIIT+RT进行12周训练对青少年健康相关身体素质成分显示出相似的效果。
