Meta-Analysis of Randomized Controlled Trials of the Effects of Tai Chi on Blood Pressure

Abstract EN

Objectives.

The purpose of this study was to investigate the influences of Tai Chi on blood pressure (BP) using the meta-analysis.

Methods.

This paper used 6 e-resource databases, and randomized controlled trials on the role of Tai Chi on blood pressure were retrieved.

Besides, the meta-analysis was conducted according to the guidelines of the Moose-recommendations and applied with Review Manager 5.3, and the risk of bias assessment was performed with the Cochrane Collaboration’s tool.

The inclusion, data extraction, and risk of bias assessment were independently finished by two researchers.

Results.

There are 24 trials meeting the criteria of inclusion and the results were reviewed.

The meta-analysis indicates that, compared with no exercise, Tai Chi had the influence of lowering systolic blood pressure (mean difference = −6.07, 95%CI (−8.75, −3.39), P<0.00001) and diastolic blood pressure (mean difference MD = −3.83, 95%CI (−4.97, −2.69), P<0.00001).

No significant discrepancies in all outcomes between Tai Chi and other aerobic exercises were discovered.

Conclusion.

Tai Chi can significantly reduce systolic and diastolic pressure than inactivity.

However, Tai Chi does not show advantages in reducing blood pressure compared to other aerobic exercises.

The trial is registered with CRD42020175306.
