摘　　要：目的 通过随机对照研究观察12周有氧运动训练对缺乏锻炼习惯的老年人肱踝脉搏波速度（baPWV）的影响,探讨有氧运动训练对动脉功能的改善作用.方法 将符合入选标准的35例平均年龄为74.7岁的老年人分为运动组17例和对照组18例.运动组进行运动强度渐进性增加的有氧运动训练,每周3次,共12周;对照组不参加运动训练计划,只作对照的项目测定.2组均在训练计划开始前及结束时测定心率、血压和baPWV.结果 运动组baPWV在有氧训练后出现明显降低,平均值从（15.88±1.67）m/s降为（14.63±1.83）m/s（P〈0.05）,同时伴有收缩压和舒张压的降低.对照组各项指标在12周的随访期间没有显著变化.结论 短期运动强度渐进性增加的有氧运动训练有助于改善缺乏良好运动习惯老年人的动脉弹性.Objective To determine the effects of a 12-week aerobic exercise program on brachial-ankle pulse wave velocity （ baPWV） in sedentary and under-exercised healthy older adults. Methods A total of 35 sedentary and unfit but healthy older adults with mean age of 74.7 years were randomly assigned to a progressively increased intensity aerobic exercise group （ n = 17） or a control group （ n = 18）. The exercise group performed aerobic exercise 3 times each week for 12 weeks. The control group didn＇t participate in the exercise program. Heart rate,blood pressure and baPWV were evaluated at admission to the aerobic exercise program and at the end of the 12 weeks in both groups. Results The mean baPWV in the aerobic exercise group decreased from 15.88 m/s to 14.62 m/s after exercise, a significant reduction. Blood pressure in the exercise group showed a decrease which was not significant. No significant improvement was identified in the control group. Conclusions Only 12 weeks of aerobic exercise with progressively increased intensity can improve arterial elasticity in sedentary and unfit older adults.
