Abstract:

Objective To provide a reasonable exercise intervention program for patients with essential hypertension(EH) by systematically reviewing, the aiming is to assess if the continuous cycle of Tai Chi Chuan exercise impacts the therapeutic effects on EH patients by the meta-analysis. Methods The randomized controlled trials(RCT) of Tai Chi Chuan treating EH were retrieved from electronic databases involving CNKI,WANFANG Database,PubMed,Cochrane Library,Science Direct and Web Of Science,and the meta-analysis was conducted by RevMan5.3 software. Results Twenty-one papers with 2 129 participants were finally selected. Meta-analysis results showed that Tai Chi Chuan exercise lasting over 12 weeks was more conductive to the decreased level of systolic blood pressure [ M D=-10.20,95% C I(-14.57,-5.83)] and diastolic blood pressure [ M D=5.12,95% C I(-7.63,-2.60)] compared with the control group. Tai Chi Chuan was found to increase the NO content of EH patients [ M D=6.87,95% C I(4.83,8.90)], improve blood lipid metabolism level including total cholesterol (TC) [ M D=0.51, 95% C I(-0.69,-0.33)], triglyceride (TG)[ M D=0.72,95% C I(-1.09,-0.36)],low-density lipoprotein cholesterol (LDL-C) [ M D=0.59,95% C I(-0.87,-0.32)] excluding high-density lipoprotein cholesterol (HDL-C). The results of subgroup analysis showed that exercise frequency ≥5 times/week and exercise duration< 60 min/d had better antihypertensive effect. Conclusion Meta-analysis indicate that Tai Chi Chuan exercise with the continuous cycle>12 weeks, the frequency ≥5 times/week and exercise duration< 60min/d demonstrates obvious effect in reducing blood pressure level and improving NO content and lipid metabolism, being worthy of promotion in clinic practices.
