短期冲刺间歇训练对普通健康人群最大摄氧量影响的Meta分析

Meta-Analysis of the Effect of Short-Term Sprint Interval Training on Maximal Oxygen Uptake in Normal Healthy People

目的:探究短期冲刺间歇训练(Short-Term Sprint Interval Training,SIT)对提高普通健康人群最大摄氧量(VO_(2max))的影响。方法 :通过检索PubMed、Web of Science、CNKI等数据库,检索SIT对普通健康人群VO_(2max)影响的随机对照组实验(Randomized Controlled Trial,RCT),按照纳入和排除标准筛选文献、提取资料并评价纳入文献的方法学质量后,采用Review Manager 5.3软件对纳入文献的结局指标进行Meta分析。SIT对VO_(2max)的提升效果优于CON组,亚分组分析显示:与无干预组相比,2 10周干预,SIT对VO_(2max)的提升效果有显著作用;与中等强度有氧训练(ET)比较,2～4周与6～8周干预,SIT提升VO_(2max)的水平不存在统计学差异(P>0.05),10周干预SIT优于ET组。结论:SIT可提高普通健康人群VO_(2max);相对于ET,SIT在2～4周与6～8周内干预效果相同,可作为替代训练,10周干预SIT干预效果优于ET,但由于相关研究较少且方法学质量评价较低,因此10周干预效果仍需进一步研究验证。······

Objective:To Explore the effect of short-term sprint interval training(SIT)on maximal oxygen(VO2max)uptake in normal healthy people.Method:By searching for databases such as PubMed,Web of Science,CNKI,etc,we found the effect of SIT on VO2max in normal healthy people in randomized controlled trial(RCT).After including and excluding criteria,we have screened literature,extracted data,and evaluated the methodological quality of the chosen literature.After that,meta-analysis of outcome indicators of the chosen literature has been done via Review Manager 5.3.The results of meta-analysis showed that SIT improved the VO2max better than the CON group,and the sub-group analysis showed that compared with the no intervention group,SIT had a significant effect on the improvement of VO2max after 2~10 weeks intervention.Compared with ET,there was no statistical difference(P>0.05)in VO2max improved by SIT between 2~4 weeks intervention and 6~8 weeks intervention;and the effect of 10 weeks SIT intervention was better than ET group.Conclusion:SIT can increase VO2max in normal healthy people.Compared with ET,SIT can be used as an alternative training because the SIT intervention effects are the same between 2~4 weeks and 6~8 weeks;and 10 weeks intervention effect of SIT is better than ET.However,due to the lack of relevant research and low evaluation of methodological quality,the effect of 10-week intervention still needs further research and verification.
