通过峰值摄氧量（vo2峰值）测量，衰老与心肺适能（CRF）的逐渐下降具有内在联系。通过体育活动改善CRF有助于更好、更健康地步入老年。高强度间歇训练（HIIT）是提高老年人CRF的有效方法，但这种训练与传统耐力训练（ET）之间的比较是模棱两可的，尤其是在老年人中。目的分析HIIT和ET对65岁及以上老年人vo2峰值的影响，并对两者进行比较。方法采用关键词在Embase、Medline、PubMed Central、ScienceDirect、Scopus和Web of Science等数据库中对论文进行全面、系统的检索。两名评论者独立评估了介入研究的潜在纳入。15项随机对照试验（rct）共纳入480名65岁及以上的老年人。在整个试验中，没有测量到高偏倚风险。结果在rct的合并分析中，与对照组相比，ET训练后的vo2峰值显著升高（平均差异- md = 1.35； 95%可信区间- ci: 0.73-1.96）。此外，发现VO2peak不仅在HIIT与对照组相比明显更高（MD = 4.61; 95% CI: 3.21-6.01），而且在HIIT与ET相比（MD = 3.76; 95% CI: 2.96-4.56）。结论高强度间歇训练和ET均能显著提高65岁及以上老年人的vo2峰值。与ET相比，HIIT后VO2peak的增益更大。然而，需要进一步的随机对照试验来证实我们在老年人群中的结果。
Background Ageing is intrinsically associated with a progressive decline in cardiorespiratory fitness (CRF) as measured by peak oxygen uptake (VO2peak). Improving CRF through physical activity contribute to better and healthy ageing. High-intensity interval training (HIIT) is a potent method of improving CRF among seniors, yet comparisons between this type of training and traditional endurance training (ET) are equivocal especially among older adults.Purpose To analyse the effects of HIIT and ET on the VO2peak of seniors aged 65 years or older when compared with controls and also when the two types of training were compared with one another.Methods A comprehensive, systematic database search for manuscripts was performed in Embase, Medline, PubMed Central, ScienceDirect, Scopus and Web of Science using key words. Two reviewers independently assessed interventional studies for potential inclusion. Fifteen randomized controlled trials (RCTs) were included totalling 480 seniors aged 65 years or over. Across the trials, no high risk of bias was measured.Results In pooled analysis of the RCTs, the VO2peak was significantly higher after ET sessions compared with controls (mean difference-MD = 1.35; 95% confidence interval-CI: 0.73-1.96). Furthermore, VO2peak was found significantly higher not only when compared HIIT with controls (MD = 4.61; 95% CI: 3.21-6.01), but also when compared HIIT with ET (MD = 3.76; 95% CI: 2.96-4.56).Conclusion High-intensity interval training and ET both elicit large improvements in the VO2peak of older adults aged 65 or over. When compared with ET, the gain in VO2peak was greater following HIIT. Nevertheless, further RCTs are therefore needed to confirm our results in senior's population.
