Twenty-five myocardial infarction patients, included in a comprehensive cardiac rehabilitation programme, were studied in order to assess the physical training effects upon several physiological parameters in a country with a tropical climate. Training consisted of three-times weekly supervised sessions with running, under telemetric control, accomplished continuously, during thirty minutes at 120 m/min as mean speed. Symptom-limited exercise stress testing was initially performed and repeated after three months of training. 88% of patients showed an increase in physical working capacity, 84% in exercise time duration and 80% in the myocardial efficiency index at subsequent ergometries. A decrease of double product and submaximal heart rate was observed. Angina, ECG ischaemic alterations and arrhythmias during exercise in the first test disappeared or occurred with higher workload in the second ergometry. Mean resting acid concentration, 1.28 +/- 0.36 mmol/l, increased immediately after exercise to 2.03 +/- 0.58 mmol/l. The prescribed physical training programme showed satisfactory results and increased the patients' quality of life, even in a humid and moderately hot climate.
25名纳入综合心脏康复计划的心肌梗死患者接受了研究，目的是评估在热带气候国家进行体育锻炼对若干生理参数的影响。训练包括每周三次在遥测控制下进行的有监督的跑步训练，持续进行30分钟，平均速度为120米/分钟。最初进行了症状限制运动应激测试，并在训练三个月后重复进行。在随后的测力计测试中，88%的患者体力工作能力增加，84%的患者运动持续时间增加，80%的患者心肌效率指数增加。观察到双乘积和次极量心率降低。第一次测试中运动期间的心绞痛、心电图缺血性改变和心律失常在第二次测力计测试中消失或在更高负荷时出现。平均静息酸浓度为1.28±0.36毫摩尔/升，运动后立即升至2.03±0.58毫摩尔/升。规定的体育锻炼计划显示出令人满意的结果，即使在潮湿和适度炎热的气候下，也提高了患者的生活质量。
