Meta analysis of the effects of high intensity interval training on metabolic syndrome in overweight college students / 中国学校卫生

ABSTRACT

Objective@#In this study, a meta analysis was conducted to evaluate and compare the effects of different types of interval training, such as, repeated sprint training(RST), high intensity interval training(HIIT) and sprint interval training(SIT) on body index of overweight/obese college students and the effect of moderate intensity continuous training(MICT), so as to provide a reference for taking appropriate exercise measures.@*Methods@#The data was searched and selected from the database of Web of Science, PubMed, Scopus, The Cochrane Library and CNKI, and from the articles about random research on the effects of HIIT, SIT, RST, and MICT on overweight/obese college students for the evaluation of bias risk. And Stata 16.0 software was used for Meta analysis and network analysis.@*Results@#Totally 815 samples selected from 18 articles were included in the study. Meta analysis showed that HIIT( SMD=-0.26, 95%CI =-0.52--0.00, P <0.05) and SIT( SMD=-0.39, 95%CI =-0.72--0.07, P <0.05) could make greater effects on BMI than MICT. The differences between RST and MICT were of no statistical significance( SMD=0.28, 95%CI =0.32-0.87, P >0.05). According to the SUCRA method combined with effect size, the best effect on improving MetS related physiological indexes of overweight college students was found in SIT( SUCRA =79.3), followed by HIIT( SUCRA =78.2), RST( SUCRA =56.8), and MICT( SUCRA =35.7).@*Conclusion@#Compared with MICT, high intensity interval training can greatly improve BMI of the obese/overweight college students, and could achieve the optimal effect of reducing the fat by exercising through SIT.
