BACKGROUND
Enhancement in maximal oxygen consumption (VO) induced by hypoxic training is important for both athletes and non-athletes. However, the lack of comparison of multiple paradigms and the exploration of related modulating factors leads to the inability to recommend the optimal regimen in different situations. This study aimed to investigate the efficacy of seven common hypoxic training paradigms on VO and associated moderators.
METHODS
Electronic (i.e., five databases) and manual searches were performed, and 42 studies involving 1246 healthy adults were included. Pairwise meta-analyses were conducted to compare different hypoxic training paradigms and hypoxic training and control conditions. The Bayesian network meta-analysis model was applied to calculate the standardised mean differences (SMDs) of pre-post VO alteration among hypoxic training paradigms in overall, athlete, and non-athlete populations, while meta-regression analyses were employed to explore the relationships between covariates and SMDs.
RESULTS
All seven hypoxic training paradigms were effective to varying degrees, with SMDs ranging from 1.45 to 7.10. Intermittent hypoxia interval training (IHIT) had the highest probability of being the most efficient hypoxic training paradigm in the overall population and athlete subgroup (42%, 44%), whereas intermittent hypoxic training (IHT) was the most promising hypoxic training paradigm among non-athletes (66%). Meta-regression analysis revealed that saturation hours (coefficient, 0.004; = 0.038; 95% CI [0.0002, 0.0085]) accounted for variations of VO improvement induced by IHT.
CONCLUSION
Efficient hypoxic training paradigms for VO gains differed between athletes and non-athletes, with IHIT ranking best for athletes and IHT for non-athletes. The practicability of saturation hours is confirmed with respect to dose-response issues in the future hypoxic training and associated scientific research.

背景
低氧训练诱导的最大摄氧量（VO）增强对运动员和非运动员都很重要。然而，缺乏多种训练模式的比较以及相关调节因素的探索，导致无法在不同情况下推荐最佳训练方案。本研究旨在调查七种常见低氧训练模式对VO及相关调节因素的效果。
方法
进行了电子检索（即五个数据库）和手动检索，纳入了42项涉及1246名健康成年人的研究。进行成对荟萃分析以比较不同的低氧训练模式以及低氧训练与对照条件。应用贝叶斯网络荟萃分析模型计算总体、运动员和非运动员群体中低氧训练模式前后VO变化的标准化平均差异（SMD），同时采用荟萃回归分析来探索协变量与SMD之间的关系。
结果
所有七种低氧训练模式都有不同程度的效果，SMD范围为1.45至7.10。间歇性低氧间歇训练（IHIT）在总体人群和运动员亚组中成为最有效的低氧训练模式的概率最高（分别为42%、44%），而间歇性低氧训练（IHT）在非运动员中是最有前景的低氧训练模式（66%）。荟萃回归分析显示，饱和小时数（系数，0.004； = 0.038；95% CI [0.0002, 0.0085]）解释了IHT引起的VO改善的差异。
结论
运动员和非运动员增加VO的有效低氧训练模式不同，IHIT对运动员最佳，IHT对非运动员最佳。在未来的低氧训练及相关科研中，就剂量反应问题而言，饱和小时数的实用性得到了证实。
