Cardiac rehabilitation programs have not consistently been shown to improve the psychological well being of their patients. In our study of 38 cardiac patients (29 men and 9 women), a variety of quality-of-life parameters were assessed before and after they completed either 12 weeks of high-intensity strength training or flexibility training added to their outpatient cardiac rehabilitation aerobic exercise program. The strength-trained patients increased their self-efficacy scores for lifting (29% vs 4%, p <0.05), push-ups (65% vs. 17%, p <0.01), climbing (36% vs 0%, p <0.001), and jogging (100% vs -9%, p <0.001), when compared with the flexibility-trained patients. The strength group also had greater improvements in Profile of Mood States dimensions: total mood disturbance (123% vs 18%, p <0.05), depression/dejection (73% vs 15%, p <0.05), and fatigue/inertia (42% vs 3% p <0.05), than did the flexibility group. The Medical Outcome Survey Short Form 36 role emotional health domain scores were significantly improved in the strength group when compared with the flexibility group (64% vs 0%, p <0.05), and the role limitation scores improved in both groups. Increases in strength were associated with enhanced self efficacy and improved mood and well-being scores (n = 34, r = 0.30 to 0.53, p <0.05). High-intensity strength training added to a cardiac rehabilitation program of selected patients leads to improvements in quality-of-life parameters. These data, in conjunction with improvements in strength, strongly support the value of adding high-intensity strength training to cardiac rehabilitation programs.
心脏康复项目并未始终如一地被证明能改善患者的心理健康。在我们对38名心脏病患者（29名男性和9名女性）的研究中，在他们完成12周的高强度力量训练或在门诊心脏康复有氧运动项目中加入柔韧性训练之前和之后，评估了各种生活质量参数。与接受柔韧性训练的患者相比，接受力量训练的患者在举重（自我效能得分提高29% 对4%，p<0.05）、俯卧撑（65% 对17%，p<0.01）、攀爬（36% 对0%，p<0.001）和慢跑（100% 对 -9%，p<0.001）方面的自我效能得分有所提高。力量训练组在情绪状态剖面图维度上也比柔韧性训练组有更大改善：总情绪紊乱（123% 对18%，p<0.05）、抑郁/沮丧（73% 对15%，p<0.05）和疲劳/惰性（42% 对3%，p<0.05）。与柔韧性训练组相比，力量训练组的医学结果调查简表36角色情绪健康领域得分显著提高（64% 对0%，p<0.05），两组的角色限制得分均有所改善。力量的增加与自我效能的提高以及情绪和幸福感得分的改善相关（n = 34，r = 0.30至0.53，p<0.05）。在选定患者的心脏康复项目中加入高强度力量训练可改善生活质量参数。这些数据，连同力量的改善，有力地支持了在心脏康复项目中加入高强度力量训练的价值。
