This study assessed the effects of aerobic exercise training on cardiovascular responses to a 5-min reaction time competition task. Twenty-seven Type A men (aged 30-56) participated in this randomized study in which 14 underwent supervised aerobic training and 13 strength training, with sessions scheduled three times per week for 12 consecutive weeks. Aerobic exercise training was associated with a 13.6% increase in VO2max compared to 2.9% for the strength group. The effects of aerobic exercise training were most evident in subjects whose initial casual blood pressure readings fell in the borderline hypertensive range (N = 5). These individuals exhibited a general reduction in diastolic blood pressure (i.e., during rest, competition, and recovery) which was associated with a fall in both heart rate and total peripheral vascular resistance. Furthermore, diastolic pressure reactivity to the competition task was attenuated in borderline hypertensive subjects who underwent aerobic conditioning. These data are interpreted as preliminary findings suggesting that borderline hypertensives may be particularly responsive to the cardiovascular benefits of aerobic conditioning. For patients who have progressed to this stage of hypertensive disease, aerobic exercise may be of ameliorative value.
本研究评估了有氧运动训练对5分钟反应时间竞赛任务心血管反应的影响。27名A型男性（年龄30 - 56岁）参与了这项随机研究，其中14人接受了有监督的有氧运动训练，13人进行了力量训练，训练课程安排为每周三次，连续进行12周。与力量训练组2.9%的增幅相比，有氧运动训练使最大摄氧量增加了13.6%。有氧运动训练的效果在初始随机血压读数处于临界高血压范围的受试者中最为明显（N = 5）。这些个体的舒张压普遍降低（即在休息、竞赛和恢复期间），这与心率和总外周血管阻力的下降有关。此外，在接受有氧训练的临界高血压受试者中，对竞赛任务的舒张压反应性减弱。这些数据被解释为初步研究结果，表明临界高血压患者可能对有氧训练带来的心血管益处特别敏感。对于已发展到高血压疾病这一阶段的患者，有氧运动可能具有改善作用。
