Background

The combination of interval training and resistance training has showed interesting results in chronic heart failure patients, corroborating the benefits of physiological adaptations of both protocols.

Objective

To evaluate the effect of the combination of interval training and resistance training program when compared to interval training alone and/or without intervention group on cardiorespiratory fitness in patients with chronic heart failure.

Methods

We search MEDLINE via PubMed, ScienceDirect, Sportdiscus, BIREME and Scielo, from their inception to December 2018. Were included both randomized and non-randomized controlled trials comparing the effect of combined training, interval training alone and/or WI group on VO_2peak (expressed in ml/kg/min), in people with chronic heart failure patients. The meta-analysis was conducted via Review Manager v 5.3 software, using random effect model.

Results

Ten articles were selected (nine randomized controlled trial), involving 401 participants. Six studies compared combined training with interval training and six studies compared combined training with the without intervention group. Eighty percent of the trials presented moderate risk of bias and twenty percent low risk of bias. Data showed significant difference and major increase in VO_2peak in favor to combined training group compared to interval training group (SMD = 0.25; CI = 0.04–0.46) and without intervention group (SMD = 0.46; CI = 0.29–0.64), respectively.

Conclusion

The combination of interval training and resistance training showed more effective in increasing cardiorespiratory fitness in patients with heart failure than interval training alone and non-exercise therapy. However, further studies should be conducted to increase the understanding of this combined training method.

联合间歇训练对心力衰竭患者心肺健康的影响：系统评价和荟萃分析。

背景

间歇训练和阻力训练的结合在慢性心力衰竭患者中显示出有趣的结果，证实了这两种方案的生理适应的益处。

客观的

评估间歇训练和阻力训练计划相结合与单独间歇训练和/或无干预组相比对慢性心力衰竭患者心肺健康的影响。

方法

我们通过 PubMed、ScienceDirect、Sportdiscus、BIREME 和 Scielo 搜索 MEDLINE，从它们成立到 2018 年 12 月。纳入了随机和非随机对照试验，比较组合训练、单独间歇训练和/或 WI 组对 VO 2peak 的_影响（以毫升/公斤/分钟表示），在慢性心力衰竭患者中。荟萃分析是通过 Review Manager v 5.3 软件使用随机效应模型进行的。

结果

选择了 10 篇文章（9 篇随机对照试验），涉及 401 名参与者。六项研究将联合训练与间歇训练进行比较，六项研究将联合训练与无干预组进行比较。百分之八十的试验存在中等偏倚风险，百分之二十的试验存在低偏倚风险。数据显示，与间歇训练组（SMD = 0.25；CI = 0.04–0.46）和无干预组（SMD = 0.46；CI = 0.29–0.64）相比，联合训练组的 VO 2peak 显着差异且显着_增加。

结论

间歇训练和阻力训练的结合在提高心力衰竭患者的心肺健康方面比单独间歇训练和非运动治疗更有效。然而，应该进行进一步的研究以增加对这种组合训练方法的理解。
