高体力活动或有氧运动训练增加老年人的中央动脉扩张性。然而，单次运动对老年人中心动脉扩张性的影响尚不清楚。此外，运动训练对运动期间中心动脉扩张性的影响尚不清楚。我们调查了老年人急性运动后全身动脉顺应性（SAC）是否发生变化，如果是这样，SAC的这种变化是否会通过有氧运动训练得到增强。7名未经训练的老年妇女（61-69岁）参加了为期6个月的运动干预研究。我们在有氧运动训练6个月之前和之后测量了急性运动（以80%的个人训练阈值骑自行车运动30分钟）后的SAC。运动训练后，个体辨别阈显著提高。此外，无论是在休息时，急性运动后30分钟的SAC显着增加后，运动训练计划。运动训练前，急性运动后SAC无显著增加，而运动训练后，急性运动后30 min SAC显著增加。本研究表明，有氧运动训练后，SAC增加急性运动后，在老年人，和SAC在休息和急性运动后，通过有氧运动训练增强，从而导致有效的适应增加心输出量在运动过程中。
High physical activity or aerobic exercise training increases central arterial distensibility in older humans. However, the effect of a single bout of exercise on central arterial distensibility in older humans is unknown. Furthermore, the effect of exercise training on central arterial distensibility during exercise is unclear. We investigated whether systemic arterial compliance (SAC) changes after acute exercise in older humans, and, if so, whether this change in SAC is enhanced by aerobic exercise training. Seven untrained older women (61–69 years old) participated in a 6-month exercise intervention study. We measured SAC after acute exercise (cycling exercise at 80% of their individual ventilatory threshold for 30 min) before and after 6 months of aerobic exercise training. After exercise training, the individual ventilatory threshold was significantly increased. In addition, both the SAC at rest and that 30 min after acute exercise were significantly increased after the exercise training program. Before exercise training, there was no significant increase in SAC after acute exercise, whereas, after exercise training, the SAC was significantly increased 30 min after acute exercise. The present study suggests that, after aerobic exercise training, SAC increases after acute exercise in older humans, and that the SAC at rest and after acute exercise is enhanced by aerobic exercise training, thereby causing an effective adaptation in increase in cardiac output during exercise.
