BACKGROUND
This study aimed to analyze the effects of a three-month remote High-Intensity Interval Training (HIIT) program as an adjunct to a multi-component clinical obesity treatment on body composition, physical fitness, movement behaviors, and nutritional habits in adolescents with obesity.
METHODS
This study was designed as a non-randomized controlled trial involving a total of 100 adolescents with obesity (BMI z-score ≥2), aged 12-17, divided into a control group (CG, receiving only standard care, i.e., medical and nutritional guidance, n = 50), and an experimental group (EG, exposed to a remote HIIT program four times/week (∼20 min/session) for 3 months, additionally to standard care, n = 50). Intervention effect was analyzed based on adherence (presence in ≥80 % of sessions). Anthropometrics, body composition, and physical fitness data were assessed at baseline and at the end of the intervention. Changes in body composition and physical fitness were the primary outcomes, while movement behaviors and nutritional habits were considered secondary outcomes.
RESULTS
Six participants were excluded from the analysis due to missing post-intervention assessments. Among the 44 (88 %) adolescents who completed the 3-month assessments, 28 were included in the adherents' group (AG) and 16 in non-adherents (non-AG). BMI z-score significantly decreased over time (β = -0.08, p = 0.001), with the AG showing a more significant reduction than non-AG (β = -0.3, p < 0.001) and CG (β = -0.29, p < 0.001). Flexibility (β = 3.5, p < 0.001) and Core strength improved (β = 2.9, p = 0.002), with no differences between the AG and non-AG. Water consumption also increased (β = 0.2, p = 0.022), but only in the AG.
CONCLUSION
The remote HIIT program was effective in improving body composition and physical fitness in adolescents with obesity. These findings highlight the potential of remote exercise interventions as a feasible and beneficial strategy within multi-component obesity treatments.
背景
本研究旨在分析为期三个月的远程高强度间歇训练（HIIT）计划作为多成分临床肥胖治疗辅助手段，对肥胖青少年的身体成分、体能、运动行为和营养习惯的影响。
方法
本研究设计为非随机对照试验，共纳入100名12至17岁的肥胖青少年（BMI z评分≥2），分为对照组（CG，仅接受标准护理，即医学和营养指导，n = 50）和实验组（EG，除标准护理外，每周接受4次远程HIIT计划（每次约20分钟），为期3个月，n = 50）。根据依从性（参加≥80%的课程）分析干预效果。在基线和干预结束时评估人体测量学、身体成分和体能数据。身体成分和体能的变化是主要结果，而运动行为和营养习惯被视为次要结果。
结果
由于干预后评估缺失，6名参与者被排除在分析之外。在完成3个月评估的44名（88%）青少年中，28名被纳入依从组（AG），16名被纳入非依从组（非AG）。BMI z评分随时间显著降低（β = -0.08，p = 0.001），AG组的降低幅度比非AG组（β = -0.3，p < 0.001）和CG组（β = -0.29，p < 0.001）更显著。柔韧性（β = 3.5，p < 0.001）和核心力量有所改善（β = 2.9，p = 0.002），AG组和非AG组之间无差异。饮水量也有所增加（β = 0.2，p = 0.022），但仅在AG组中。
结论
远程HIIT计划对改善肥胖青少年的身体成分和体能有效。这些发现凸显了远程运动干预作为多成分肥胖治疗中一种可行且有益策略的潜力。
