太极拳锻炼的降血压作用:一项元分析

Curative Effect of Tai Chi on Blood Pressure:a Mate-Analysis

目的:习练我国民族传统体育运动项目太极拳,有利于增进人们健康。近来不少研究关注太极拳锻炼对血压的积极影响,这项元分析的目的就是要更加准确地评估这种影响。方法:使用中、英文关键词"太极拳、Tai Chi",通过计算机检索4个数据库。使用RveMan4.2软件,采用标准均差方法计算总效果量和95%置信区间。研究结果:共检索到3339篇中、英文文献,根据纳入标准,最后确定33篇文献纳入元分析,其中设随机对照组文献15篇、自身前后对照文献18篇,总样本量n=1633。太极拳锻炼对收缩压作用的总效果量为d=-0.93,95%置信区间为(-1.18,10.68);对舒张压作用的总效果量为d=-0.779,5%置信区间为(-1.02,-0.52)。结论:太极拳锻炼能有效地降低收缩压与缩张压,效果量分别达到大效果和中效果。

PURPOSE ： Tai Chi exercise is a traditional Chinese exercise and is proved to be beneficial for health. Some research have recently focus on its potential effect on blood pressure. A goal of this meta -analysis was to estimate this effect of Tai Chi. METHODS： A computerized search of 4 databases were done using key words and the two languages of English and Chinese. RveMand. 2 software was used to calculate the standardized mean differences （ESsm） and the 95% confidence intervals （CI） RESULTS： Of 3339 citations obtained, only 33 papers focused on blood pressure in response to Tai Chi exercise with 1633 subjects. Systolic blood pressure effect of Tai Chi Exercise on the total effect size was d = - 0. 93,95% confidence interval （-1.18,10.68） ; Tai Chi exercise on diastolic function of the overall effect size was d = - 0.77,95% confidence interval is （ - 1.02, - 0.52）. CONCLUSIONS： This meta-analysis suggests that Tai Chi may be an good treatment of high blood pressure, lowing both SBP and DBP.
