In previous investigations, we have been able to demonstrate that healthy individuals and CHD patients with normal exercise capacity experience changes in cardiovascular parameters, metabolism and sympathetic activity during light swimming exercise, changes which are not observed in seated bicycle ergometry at an exercise level of less than 2 W/kg-1. We have now examined 12 post-infarction patients (54.3 +/- 6 years) with limited exercise capacity (1.2 +/- 0.3 W/kg-1), who have been participating in physical therapy for 29 months (median time) under continuous medication. The examination comprised incremental seated bicycle ergometry and, approximately 60 min later, light swimming (2 to 3 x 2 min; speed v = 0.33 +/- 0.02 m.s-1; T = 28 degrees C). The changes in heart rate, blood pressure, lactate, glucose, adrenaline and noradrenaline levels during the swimming exercise were equivalent in mean value to ergometry at the 100 W level. Three patients had to discontinue swimming before the scheduled time, due to considerable arrhythmias. Three other patients stopped swimming because of subjective overexertion. The exercise reaction was less favorable among those unaccustomed to swimming than among regular swimmers.
在先前的研究中，我们已经能够证明，健康个体以及运动能力正常的冠心病患者在轻度游泳运动期间心血管参数、代谢和交感神经活动会发生变化，而在低于2W/kg-1运动水平的坐姿自行车测力计测试中未观察到这些变化。我们现在检查了12名心肌梗死后患者（年龄54.3±6岁），他们的运动能力有限（1.2±0.3W/kg-1），在持续药物治疗下参加了29个月（中位时间）的物理治疗。检查包括递增式坐姿自行车测力计测试，大约60分钟后进行轻度游泳（2至3次，每次2分钟；速度v = 0.33±0.02m·s-1；水温T = 28摄氏度）。游泳运动期间心率、血压、乳酸、葡萄糖、肾上腺素和去甲肾上腺素水平的变化平均值与100W水平的测力计测试相当。三名患者因严重心律失常不得不在预定时间前停止游泳。另外三名患者因主观上过度劳累而停止游泳。不习惯游泳的患者的运动反应不如经常游泳的患者。
