Existing literature has shown that patients with coronary artery disease (CAD) can benefit greatly from the strength training; therefore, the strength training should play a more important role in cardiac rehabilitation. However, the medical community may still have conservation to apply the strength training owing to no comprehensive study so far to compare the effectiveness of the strength training to the other trainings, such as aerobic training.
To evaluate the effect of strength training on motor function in patients with CAD.
Published articles from the earliest date available to July 2015 were identified using electronic searches. Two reviewers selected independently relevant randomized controlled trials (RCTs) investigating exercise program with strength training versus control interventions (exercise without strength training, including aerobic training and no exercise group) for the treatment of CAD patients. We examined effects of exercise with strength training versus control interventions on peak oxygen uptake (VO2peak), duration of exercise test and muscle strength. Two reviewers extracted data independently.
Twenty seven trials that represented 1151 participants passed the selection criteria and were evaluated for the effects of strength training in CAD patients. For improving VO2peak [SMD (95%CI) = 0.58 (0.11, 1.06)] and muscle strength [upper limb, SMD (95% CI) =0.44 (0.34, 0.55); lower limb, SMD (95% CI) =0.33 (0.16, 0.50)], exercise program with strength training were significantly more effective than one without it. But there is no significantly difference on duration of exercise test [SMD (95%CI) = 0.17 (-0.04, 0.39)] in strength training group than in control group.
We conclude strength training is effective in improving muscle strength and VO2peak, in CAD patients, when compared to patients with control group. Furthermore, our evaluations suggest that strength training does not compromise clinical trial completion or safety.
现有文献表明，冠心病（CAD）患者能从力量训练中大幅获益；因此，力量训练在心脏康复中应发挥更重要的作用。然而，由于目前尚无全面研究比较力量训练与其他训练（如有氧训练）的效果，医学界在应用力量训练方面可能仍有所保留。
评估力量训练对CAD患者运动功能的影响。
通过电子检索确定从最早可获取日期至2015年7月发表的文章。两名评审员独立选择相关随机对照试验（RCT），这些试验研究了针对CAD患者的力量训练运动方案与对照干预措施（无力量训练的运动，包括有氧训练和无运动组）。我们检查了力量训练运动与对照干预措施对峰值摄氧量（VO2peak）、运动测试持续时间和肌肉力量的影响。两名评审员独立提取数据。
27项试验（代表1151名参与者）通过了选择标准，并对CAD患者力量训练的效果进行了评估。对于改善VO2peak [标准化均数差（SMD）（95%置信区间）=0.58（0.11，1.06）]和肌肉力量[上肢，SMD（95%置信区间）=0.44（0.34，0.55）；下肢，SMD（95%置信区间）=0.33（0.16，0.50）]，有力量训练的运动方案比无力量训练的方案显著更有效。但力量训练组与对照组在运动测试持续时间[SMD（95%置信区间）=0.17（-0.04，0.39）]上无显著差异。
我们得出结论，与对照组患者相比，力量训练对改善CAD患者的肌肉力量和VO2peak有效。此外，我们的评估表明，力量训练不会影响临床试验的完成或安全性。
