摘要： 目的:探討高強度間歇訓(xùn)練(HIIT)相比中強度持續(xù)訓(xùn)練(MICT)對超重/肥胖成人體重與體脂率的干預(yù)是否更具優(yōu)勢。方法:通過檢索PubMed、Embase、Web of Science與中國知網(wǎng)(中文核心期刊)數(shù)據(jù)庫,搜集HIIT與MICT干預(yù)超重/肥胖成人體重與體脂率的隨機對照試驗(RCT)與臨床對照試驗(CCT),采用風(fēng)險偏倚評價對納入文獻(xiàn)進(jìn)行質(zhì)量評估,STATA 13.1軟件進(jìn)行合并效應(yīng)量分析和亞組分析。結(jié)果:共納入文獻(xiàn)10篇,其中低、中度與高風(fēng)險文獻(xiàn)分別為4篇、4篇與2篇。納入文獻(xiàn)中HIIT與MICT組總樣本量分別為119個與114個。Meta分析結(jié)果發(fā)現(xiàn),與MICT相比,HIIT對超重/肥胖成人體重(WMD=-0.18,95% CI:-1.03～0.66,P=0.67)與體脂率(WMD=-0.38,95% CI:-1.02～0.27,P=0.25)的影響均不顯著。亞組分析結(jié)果顯示,超重指標(biāo)中多訓(xùn)練次數(shù)的“≥48次”亞組(WMD=-1.51,95% CI:-2.73～-0.29,P=0.016)具有統(tǒng)計學(xué)意義;體脂率指標(biāo)中長周期的“12周”亞組(WMD =-0.73,95% CI:-1.49～0.03,P=0.061)與多訓(xùn)練次數(shù)的“≥48次”亞組(WMD=-1.14,95% CI:-2.43～0.15,P=0.084)均出現(xiàn)邊界顯著效應(yīng)。結(jié)論:HIIT與MICT相比在降低超重/肥胖成人的體重與體脂率方面的作用無明顯差異。

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
