BACKGROUND
High-intensity interval training (HIIT) may be a feasible and efficacious strategy for improving health-related fitness in young people. The objective of this systematic review and meta-analysis was to evaluate the utility of HIIT to improve health-related fitness in adolescents and to identify potential moderators of training effects.
METHODS
Studies were considered eligible if they: (1) examined adolescents (13-18 years); (2) examined health-related fitness outcomes; (3) involved an intervention of ≥4 weeks in duration; (4) included a control or moderate intensity comparison group; and (5) prescribed high-intensity activity for the HIIT condition. Meta-analyses were conducted to determine the effect of HIIT on health-related fitness components using Comprehensive Meta-analysis software and potential moderators were explored (ie, study duration, risk of bias and type of comparison group).
RESULTS
The effects of HIIT on cardiorespiratory fitness and body composition were large, and medium, respectively. Study duration was a moderator for the effect of HIIT on body fat percentage. Intervention effects for waist circumference and muscular fitness were not statistically significant.
CONCLUSIONS
HIIT is a feasible and time-efficient approach for improving cardiorespiratory fitness and body composition in adolescent populations.
背景
高强度间歇训练（HIIT）可能是提高年轻人健康相关体能的一种可行且有效的策略。本系统评价和荟萃分析的目的是评估 HIIT 对改善青少年健康相关体能的效用，并确定训练效果的潜在调节因素。
方法
如果研究符合以下标准，则被认为是合格的：（1）研究对象为青少年（13-18 岁）；（2）研究健康相关体能结果；（3）干预持续时间≥4 周；（4）包括对照组或中等强度比较组；（5）为 HIIT 条件规定高强度活动。使用 Comprehensive Meta-analysis 软件进行荟萃分析，以确定 HIIT 对健康相关体能成分的影响，并探讨潜在的调节因素（即研究持续时间、偏倚风险和比较组类型）。
结果
HIIT 对心肺功能和身体成分的影响分别较大和中等。研究持续时间是 HIIT 对体脂百分比影响的调节因素。HIIT 对腰围和肌肉力量的干预效果不具有统计学意义。
结论
HIIT 是提高青少年人群心肺功能和身体成分的一种可行且高效的方法。
