The purpose of this study was to examine the effects of walking on resting systolic and diastolic blood pressure in adults.
A total of 24 primary outcomes from 16 studies and 650 subjects (410 exercise, 240 control) met the criteria for inclusion: (1) randomized and nonrandomized controlled trials, (2) walking as the only intervention, (3) subjects apparently sedentary, (4) adult humans > or =18 years of age, (5) English-language studies published between January 1966 and December 1998, (6) resting blood pressure assessed, (7) training studies > or =4 weeks.
Using a random effects model, statistically significant decreases of approximately 2% were found for both resting systolic and diastolic blood pressure (systolic, mean +/- SEM = -3 +/- 1 mm Hg, 95% confidence interval: -5 to -2 mm Hg; diastolic, mean +/- SEM = -2 +/- 1 mm Hg, 95% confidence interval: -3 to -1 mm Hg).
Walking exercise programs reduce resting blood pressure in adults.
本研究的目的是探讨步行对成年人静息收缩压和舒张压的影响。
16项研究中的24项主要结果以及650名受试者（410名运动组，240名对照组）符合纳入标准：（1）随机和非随机对照试验；（2）步行作为唯一干预措施；（3）受试者明显久坐不动；（4）18岁及以上的成年人；（5）1966年1月至1998年12月发表的英文研究；（6）评估静息血压；（7）训练研究持续4周及以上。
使用随机效应模型，发现静息收缩压和舒张压均有统计学意义的显著下降，约2%（收缩压，均值±标准误=-3±1mmHg，95%置信区间：-5至-2mmHg；舒张压，均值±标准误=-2±1mmHg，95%置信区间：-3至-1mmHg）。
步行锻炼计划可降低成年人的静息血压。
