目的 系统评价不同强度间歇训练对超重/肥胖青少年身体成分的影响。方法 检索PubMed、Web of Science、ScienceDirect、中国知网、万方等数据库及ClinicalTrials.gov、ISRCTN等注册平台发表的相关研究。使用Stata 17.0进行网状Meta分析,并计算累积排名曲线下面积(surface under the cumulative ranking curve,SUCRA)对不同训练方案进行排序。结果 共纳入33篇文献,共计1051名超重/肥胖青少年。与对照组相比,高强度间歇训练(high-intensity interval training,HIIT)、中等强度间歇训练(moderate-intensity interval training,MIIT)、冲刺间歇训练(sprint interval training,SIT)及中等强度持续训练(moderate-intensity continuous training,MICT)均可改善体脂率、体质量和腰围等指标;网状比较显示,HIIT在降低体脂率、体质量及腰围方面的综合排序最优,而MICT在降低体质量指数(body mass index,BMI)方面相对更优。结论 不同强度间歇训练均有助于改善超重/肥胖青少年的身体成分,其中HIIT可能是减脂与控制腰围的优选方式,干预周期12周,2~4次/周;BMI改善可优先考虑MICT,建议周期为12周,3次/周。

Objective To systematically evaluate the effects of different intensities of interval training on body composition in overweight/obese adolescents.Methods Relevant studies published in databases including PubMed, Web of Science, ScienceDirect, CNKI, Wanfang, and trial registries such as ClinicalTrials.gov and ISRCTN were searched.A network Meta-analysis was conducted using Stata 17.0,and the surface under the cumulative ranking curve (SUCRA) was calculated to rank different training protocols.Results A total of 33 studies involving 1,051 overweight/obese adolescents were included.Compared with the control group,high-intensity interval training (HIIT),moderate-intensity interval training (MIIT),sprint interval training (SIT),and moderate-intensity continuous training (MICT) all improved body fat percentage, body mass, and waist circumference.Network comparisons showed that HIIT ranked best for reducing body fat percentage,body mass,and waist circumference,while MICT was relatively better for reducing body mass index (BMI).Conclusions Different intensities of interval training all help improve body composition in overweight/obese adolescents.HIIT may be the preferred approach for fat loss and waist circumference control,with an intervention period of 12 weeks,2-4 times per week.For BMI improvement,MICT may be prioritized,with a recommended period of 12 weeks,3 times per week.
