摘要
目的探讨不同运动强度对老老年单纯收缩期高血压(ISH)患者血管功能的影响。方法 ISH患者306例随机分为低强度运动组(低强度组,n=102)、中强度运动组(中强度组,n=100),自然活动组(对照组,n=104),在血压控制达标的前提下按设定运动强度运动12 w。以踝肱指数(ABI)和脉搏波传导速度(PWV)作为血管功能的评价指标,观察不同强度的运动对老老年ISH患者血管功能的影响。结果 ABI值和PWV值均与增龄密切相关,80岁以上老老年人群,年龄每增加1岁,ABI降低0. 019,PWV则增加0. 609 m/s。运动后低、中强度组收缩压(SBP)均显著降低〔(127. 4±8. 6) vs(126. 8±7. 3) mm Hg,P<0. 05〕、〔(128. 8±7. 0) vs(127. 1±5. 7) mm Hg,P<0. 01〕,中强度组舒张压(DBP)显著降低〔(82. 4±3. 5) vs(80. 8±2. 8) mm Hg,P<0. 01〕。运动后低、中强度组ABI值均显著增高〔(0. 78±0. 08) vs (0. 79±0. 07),P <0. 01〕、〔(0. 76±0. 07) vs(0. 82±0. 08),P<0. 01〕; PWV值均显著降低〔(16. 95±2. 54) vs(15. 57±2. 16) m/s,P<0. 01〕、〔(16. 92±3. 22)比(15. 11±2. 85) m/s,P<0. 01〕。与对照组比较,低强度组、中强度组前后ABI增幅均显著大(均P <0. 01),PWV降幅均显著大(均P <0. 01);与低强度组比较,中强度组对ABI和PWV的改变显著优于低强度组(P<0. 01,P<0. 05)。结论老老年人群血管功能与增龄密切相关(其中ABI与增龄呈负相关,PWV与增龄呈正相关)。低中强度运动均能降低老老年ISH患者的血管硬化度,且中强度优于低强度。
