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.
【摘要】 目的 比较不同类型间歇训练与持续训练对改善大学生心肺适能的效果, 为大学生健康促进提供干预方法的证 据支持。 方法 米用 Meta 分析的方法, 检索 Web of Science、PubMed、Science Direct、Scopus、the Cochrane Library 和 CNKI 等 数据库中建库至 2020 年 4 月 1 日关于传统高强度间歇训练 (high-intensity interval training, HIIT)、重复冲刺训练 (repeated-sprint training, RST) 及短跑间歇训练 (sprint-interval training, SIT) 干预久坐不运动大学生的随机对照实验研究文献, 由 2 名研究者独立对文献进行筛选、数据提取及偏倚风险的评估, 采用 Stata 16.0 软件依次进行传统 Meta 分析及网状 Meta 分 析。 结果 共纳入 21 篇文献 728 名样本; Meta 分析显示 HIIT ( SMD = 0.35, 95% CI = 0.10~0.60, P<0.05), SIT ( SMD = 0.38, 95%CI =0.05~0.70, P<0.05)在提高 VO 2 max 指标上优于中等强度持续运动 (moderate-intensity continuous training, MICT)、RST ( SMD = –0.08, 95% CI = –0.41~0.25, P>0.05)对比 MICT 差异无统计学意义; HIIT ( SMD = 0.40, 95% CI =0.08 ~0.72, P< 0.05)、SIT ( SMD = 0.35, 95% CI = 0.03 ~0.67, P<0.05) 提高 VO 2 max 指标方面优于 RST, HIIT 与 SIT ( SMD = 0.05, 95% CI = –0.25~0.36, P>0.05) 之间差异无统计学意义; 4 种训练方式提高 VO 2 max 指标的效果大小可能性排序为 HIIT 与 SIT 高于RST及 MICT, 且HIIT高于SIT, RST 高于 MICT。 结论 高强度间歇训练改善 VO 2 max 的效果整体优于 MICT, 且采用 HIIT 进行训练可能效果最好。
