To evaluate the effects of high-intensity interval training (HIIT), in comparison with those of continuous exercise, on functional capacity and cardiovascular variables in patients with COPD, through a systematic review and meta-analysis of randomized controlled trials.
We searched PubMed, the Physiotherapy Evidence Database, the Cochrane Central Register of Controlled Trials, and EMBASE, as well as performing hand searches, for articles published up through January of 2017. We included studies comparing exercise regimens of different intensities, in terms of their effects on functional capacity and cardiovascular variables in patients with COPD.
Of the 78 articles identified, 6 were included in the systematic review and meta-analysis. Maximal oxygen consumption (VO2max) did not differ significantly between HIIT and control interventions. That was true for relative VO2max (0.03 mL/kg/min; 95% CI: -3.05 to 3.10) and absolute VO2max (0.03 L/min, 95% CI: -0.02 to 0.08).
The effects of HIIT appear to be comparable to those of continuous exercise in relation to functional and cardiovascular responses. However, our findings should be interpreted with caution because the studies evaluated present a high risk of bias, which could have a direct influence on the results.
通过对随机对照试验的系统评价和荟萃分析，评估高强度间歇训练（HIIT）与持续运动相比对 COPD 患者功能能力和心血管变量的影响。
我们检索了 PubMed、物理治疗证据数据库、Cochrane 对照试验中心注册库和 EMBASE，并进行了手工检索，以查找截至 2017 年 1 月发表的文章。我们纳入了比较不同强度运动方案对 COPD 患者功能能力和心血管变量影响的研究。
在确定的 78 篇文章中，有 6 篇被纳入系统评价和荟萃分析。HIIT 与对照组干预措施相比，最大摄氧量（VO2max）没有显著差异。相对 VO2max（0.03 mL/kg/min；95%CI：-3.05 至 3.10）和绝对 VO2max（0.03 L/min，95%CI：-0.02 至 0.08）也是如此。
HIIT 的效果似乎与持续运动相当，与功能和心血管反应有关。然而，由于评估的研究存在高偏倚风险，这可能直接影响结果，因此我们的发现应谨慎解释。
