从我们的档案中回顾选择了24名年龄在70岁及以上的受试者，对他们进行了心血管疾病症状的筛查。所有受试者的基线运动试验心肌缺血均为阴性。所有受试者都完成了为期8周的计划，根据不同的适应症进行，包括有氧体育训练计划，包括每周骑自行车30分钟，每周三次，最大心率的65%到75%，在注册时进行运动测试，教育干预，饮食建议，和心理支持。所有受试者在运动训练前和运动结束时进行心肺运动试验(CPX)。在每次CPX结束时，记录最大摄氧量(VO2峰值)、每单位二氧化碳产生增加的通气量增加率(VE/VCO2斜率)和心率。25例年龄在60岁以下、无运动性心肌缺血证据且未参加任何运动训练的健康受试者，也是从我们的档案中回顾性选取的25名健康受试者，作为对照组进行HRR分析。这些患者相隔几周进行了两次运动测试。一些研究表明，迷走神经张力的变化可以作为一种结果工具，帮助识别患有或不患有心血管疾病的患者或受试者发生心血管事件的风险，尽管HRR在没有心血管疾病的老年受试者中具有预后价值的证据相当有限。在这项研究中，运动训练改善了健康老年人的HRR，这表明运动训练也改善了没有心血管疾病的老年人的迷走神经/交感神经平衡。观察到的HRR的改善是否具有长期有益的预后影响并不是研究的目的，尽管根据Framingham的数据，可能会有有益的影响
Twenty-four subjects aged 70 and older were retrospectively selected from our archives and screened for symptoms of cardiovascular disease. Baseline exercise test was negative for myocardial ischemia in all subjects. All subjects had completed an 8-week program, performed for a variety of indications and consisting of an aerobic physical training program including 30 minutes of cycling three times per week at 65% to 75% of maximum heart rate achieved at peak exercise test performed at enrollment, an educational intervention, dietary advice, and psychological support. All subjects underwent a cardiopulmonary exercise test (CPX) before and at the end of exercise training. At the end of each CPX, peak oxygen uptake (VO2peak), the rate of increase of ventilation per unit of increase of carbon dioxide production (VE/VCO2slope), and HRR were recorded. Twenty-five healthy subjects younger than 60 with no evidence of exercise-induced myocardial ischemia and not enrolled in any exercise training program were also retrospectively selected from our archives and used as a control group for analyzing HRR. These patients performed two exercise tests several weeks apart. Several studies have shown that changes in vagal tone can be used as an outcome tool that helps identify patients or subjects with or without cardiovascular disease at risk for a cardiovascular event, although the evidence of a prognostic value of HRR in older subjects without cardiovascular disease is rather poor. In this study, exercise training resulted in HRR improvement in healthy elderly subjects, suggesting that exercise training improves vagal/sympathetic balance in older subjects without cardiovascular disease as well. Whether the observed improvement in HRR may have long-term beneficial prognostic effects was not the aim of the study, although a beneficial effect might be postulated, in light of the Framingham data
