The effect of interval exercise training on the peak coital heart rate in post myocardial infarction patients was studied. Sixteen men (ages 46-54) underwent a 16-week bicycle ergometer training program 12 to 15 weeks following their first myocardial infarction. Portable ECG tape recorders were used to record the ECG during coitus twice before and twice after the training program. The maximum minute oxygen consumption (VO2max) was measured in each subject during bicycle ergometer ECG examinations before and after the training program. A control group of six post myocardial infarction patients who were not trained was evaluated in the same manner. The exercise-trained group had an average increase in VO2max of 11.5%(2.7 to 3.0 L/min) and an average decrease in peak coital heart rate of 5.5%(127/min to 120/min). The control group demonstrated a 2% increase in VO2max and no significant change in peak coital heart rate. The increase in aerobic capacity (VO2max) and the consequent reduction in peak coital heart rate in our trained group suggests the potential value of exercise training in improving sexual function in the patient with angina during coitus.
研究了间歇运动训练对心肌梗死后患者性交时最高心率的影响。16名男性（年龄46 - 54岁）在首次心肌梗死后12至15周接受了为期16周的自行车测力计训练计划。在训练计划前后，使用便携式心电图磁带记录器在性交期间记录心电图两次。在训练计划前后的自行车测力计心电图检查期间，测量每个受试者的最大分钟耗氧量（VO2max）。以同样的方式评估了6名未经训练的心肌梗死后患者的对照组。运动训练组的VO2max平均增加了11.5%（从2.7升至3.0升/分钟），性交时最高心率平均降低了5.5%（从127次/分钟降至120次/分钟）。对照组的VO2max增加了2%，性交时最高心率无显著变化。我们训练组有氧能力（VO2max）的增加以及随之而来的性交时最高心率的降低表明，运动训练对于改善心绞痛患者性交时的性功能具有潜在价值。
