Interval training for cardiopulmonary fitness of college students: a network Meta-analysis / 中国学校卫生

ABSTRACT

Objective@#To compare the effects of different types of high-intensity interval training and moderate-intensity steady training on improving cardiorespiratory fitness of college students, and to provide evidence supporting intervention methods for health promotion of college students.@*Methods@#By using the method of Meta-analysis, Web of science, PubMed, Scopus and CNKI database was searched for randomized control trails regarding high-intensity intervention (HIIT), repeated-sprint training (RST) and sprint-interval training (SIT) among sedentary college students in April 1, 2020. Two independent researchers conducted literature filtering, data extraction, risk of bias assessment, as well as traditional Meta-analysis and network Meta-analysis by using Stata software version 16.0.@*Results@#A total of 21 articles and 728 participants were included. Meta-analysis showed that HIIT (SMD=0.35, 95%CI=0.10-0.60, P<0.05) and SIT (SMD=0.38, 95%CI=0.05-0.70, P<0.05) were significantly better than MICT, there was no statistical difference in RST (SMD=-0.08, 95%CI=-0.41-0.25, P>0.05) compared with MICT; HIIT (SMD=0.40, 95%CI=0.08-0.72, P<0.05) and SIT (SMD=0.35, 95%CI=0.03-0.67, P<0.05) were significantly better than RST, there was no significant difference between HIIT and SIT(SMD=0.05, 95%CI=-0.25-0.36, P>0.05). The ranking of the four training methods for improving the effect size of VO 2max index was HIIT>SIT>RST>MICT.@*Conclusion@#The overall effect of high intensity interval training on VO 2max is better than MICT, and HIIT training may be the best.
