Interval training for cardiopulmonary fitness of college students: a network Meta-analysis

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.

【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。
