高强度间歇训练与中强度持续训练对超重/肥胖成人体成分干预作用的比较:Meta分析

摘要： 目的:探讨高强度间歇训练(HIIT)相比中强度持续训练(MICT)对超重/肥胖成人体重与体脂率的干预是否更具优势。方法:通过检索PubMed、Embase、Web of Science与中国知网(中文核心期刊)数据库,搜集HIIT与MICT干预超重/肥胖成人体重与体脂率的随机对照试验(RCT)与临床对照试验(CCT),采用风险偏倚评价对纳入文献进行质量评估,STATA 13.1软件进行合并效应量分析和亚组分析。结果:共纳入文献10篇,其中低、中度与高风险文献分别为4篇、4篇与2篇。纳入文献中HIIT与MICT组总样本量分别为119个与114个。Meta分析结果发现,与MICT相比,HIIT对超重/肥胖成人体重(WMD=-0.18,95% CI:-1.03～0.66,P=0.67)与体脂率(WMD=-0.38,95% CI:-1.02～0.27,P=0.25)的影响均不显著。亚组分析结果显示,超重指标中多训练次数的“≥48次”亚组(WMD=-1.51,95% CI:-2.73～-0.29,P=0.016)具有统计学意义;体脂率指标中长周期的“12周”亚组(WMD =-0.73,95% CI:-1.49～0.03,P=0.061)与多训练次数的“≥48次”亚组(WMD=-1.14,95% CI:-2.43～0.15,P=0.084)均出现边界显著效应。结论:HIIT与MICT相比在降低超重/肥胖成人的体重与体脂率方面的作用无明显差异。

Abstract: Objective: To determine the effectiveness of high-intensity interval training (HIIT) on body mass and body fat percentage in overweight and obese adults, in comparison with moderate-intensity continuous training (MICT). Methods: Four electronic databases (PubMed, Embase, Web of Science, and the China National Knowledge Infrastructure) were searched for randomized controlled trial (RCT) or clinical controlled trial (CCT) comparing the effect of HIIT and MICT on body mass and fat percentage in overweight and obese adults. The risk of bias assessment was performed for each of the included studies. The meta-analysis was performed by using STATA 13.1. Results: Ten studies, including 119 participants in HIIT and 114 participants in MICT, met the eligibility criteria and were included in the meta-analysis. No statistically significant difference between HIIT and MICT was observed for body mass (WMD=-0.18,95% CI:-1.03～0.66,P=0.67) and fat percentage (WMD=-0.38, 95% CI: -1.02～0.27, P=0.25). However, a significant reduction in body mass following HIIT compared with MICT was observed in subgroups "48 times" (WMD=-1.51,95% CI:-2.73～-0.29,P=0.016), while marginally significant reduction in fat% following HIIT compared with MICT was observed in subgroups "12 weeks" (WMD =-0.73, 95% CI: -1.49～0.03, P=0.061) and "48 times" (WMD=-1.14,95% CI:-2.43～0.15,P=0.084). Conclusion: The effects of HIIT and MICT
