目得：这项随机对照研究评估了增加高强度力量训练计划是否（最大值的80%）进行门诊心脏康复治疗是一种安全有效的改善肌肉力量和身体成分的方法。38名心脏病患者志愿者（29名男性和9名女性）被随机分配到高强度力量训练或灵活性训练，同时加入12-每周门诊心脏康复有氧运动计划。在训练完成前后测量肌肉力量、局部肌肉耐力、关节柔韧性、最大跑台耐受时间和身体成分。力量训练的患者（n = 18）的平均力量增加更大（90 +/- 19%对9 +/-4%，P < 0.0001）和局部肌肉耐力（20次对6次，P < 0.0001），并且对于提升初始一次重复最大负荷的平均感知用力降低（11 +/- 1对15 +/- 1，P < 0.0001），与灵活性训练的患者（n = 16）相比。力量组减掉了更多的身体脂肪（2.8 +/- 2.0 vs 1.3 +/- 2.0 kg，P < 0.01），倾向于获得更多瘦肉组织（1.5 +/- 2.3 vs 0.5 +/- 1.2 kg，P < 0.10），并且在跑台时间上有更大的改善（2.3 +/- 1.3对1.2 +/- 1.0分钟，P < 0.02）。每组的关节灵活性改善情况相似。没有一个科目有证据表明，心脏缺血或心律失常的训练sessions.CONCLUSIONS：医疗监督的高强度力量训练是耐受性良好的，当添加到有氧训练的心脏康复计划，并允许患者积极获得的力量和耐力，他们将需要完成日常生活任务，在较低的感知努力。力量训练还通过改善身体成分和最大跑步机运动时间来降低心脏病风险因素。
PURPOSE: This randomized controlled study assessed whether adding a program of high-intensity strength training (80% of maximum) to an outpatient cardiac rehabilitation program would be a safe and effective means of improving muscle strength and body composition.METHODS: Thirty-eight cardiac patient volunteers (29 men and 9 women) were randomized to either high-intensity strength training or flexibility training added concurrently to a 12-week outpatient cardiac rehabilitation aerobic exercise program. Muscle strength, local muscle endurance, joint flexibility, maximum treadmill tolerance time, and body composition were measured before and after completion of the training.RESULTS: The strength-trained patients (n = 18) had greater increases in mean strength (90 +/- 19% versus 9 +/- 4%, P < 0.0001) and local muscle endurance (20 versus 6 times, P < 0.0001), and decreases in mean perceived exertion for lifting the initial one repetition maximum load (11 +/- 1 versus 15 +/- 1, P < 0.0001) when compared with flexibility-trained patients (n = 16). The strength group lost more body fat (2.8 +/- 2.0 versus 1.3 +/- 2.0 kg, P < 0.01), tended to gain more lean tissue (1.5 +/- 2.3 versus 0.5 +/- 1.2 kg, P < 0.10), and had greater improvements in treadmill time (2.3 +/- 1.3 versus 1.2 +/- 1.0 minute, P < 0.02) than did the flexibility group. Improvements in joint flexibility were similar for each group. None of the subjects had evidence of cardiac ischemia or arrhythmia during the training sessions.CONCLUSIONS: Medically supervised high-intensity strength training is well tolerated when added to the aerobic training of cardiac rehabilitation programs and allows patients to aggressively gain the strength and endurance they will need to complete daily living tasks at lower perceived efforts. Strength training also reduces cardiac risk factors by improving body composition and maximum treadmill exercise time.
