本研究评估了12周有监督的训练，每周两次，每次至少45分钟，对心肌梗死（MI）后的身体表现和心理健康的长期影响。69名患者被随机分为运动组和非运动组。心肌梗死后6周的最大运动能力与血清中天门冬氨酸转氨酶的急性峰值值呈负相关，作为梗死面积的指标。心肌梗死后一年，训练组的健身水平（10%）的增加没有显著超过对照组（2%）（p = 0.10）。在自我评定的心理健康和身体得分或重返工作岗位率方面，没有组间差异。在训练组中，而不是在对照组中，在休闲时间活动中感知到的呼吸困难的变化与客观测量的峰值运动能力呈正相关。我们得出的结论是，在训练结束后6个月，心肌梗死后的身体表现只有轻微的改善，与常规护理方案相比，没有明显的长期心理益处。因此，在心肌梗死后进行有监督的常规锻炼计划的适应性影响受到质疑。
This study evaluated long-term effects of 12 weeks of supervised training, of at least 45 minutes duration with two sessions per week, on physical performance and psychological well-being after myocardial infarction (MI). Sixty-nine patients were randomized to either an exercise or a nonexercise group. Maximum exercise capacity 6 weeks post-MI was inversely related to the acute peak aspartate aminotransferase values in serum, as an index of infarct size. One year post-MI, the increase in level of fitness (10%) in the training group did not significantly exceed (p = .10) that of the controls (2%). No intergroup differences were registered in self-rated psychological well-being and physical scores or in the return to work rate. In the training group, but not in the controls, the change in perceived dyspnoea at leisure-time activities was positively related to the objectively measured peak exercise capacity. We conclude that after MI only marginal improvements in physical performance are achieved 6 months after training is finished, with no long-term psychological benefits apparent versus a usual care program. The adaptive implications of supervised conventional exercise programs post-MI are therefore questioned.
