Abstract

BACKGROUND

Heart rate variability (HRV) as an accurate, noninvasive measure of the Autonomous Nervous System (ANS) can reflect mental health (e.g., stress, depression, or anxiety). Tai Chi and Yoga (Tai Chi/Yoga), as the most widely practiced mind⁻body exercises, have shown positive outcomes of mental health. To date, no systematic review regarding the long-lasting effects of Tai Chi/Yoga on HRV parameters and perceived stress has been conducted.

OBJECTIVE

To critically evaluate the existing literature on this topic.

METHODS

Five electronic databases (Web of Science, PubMed, Scopus, SportDiscus and Cochrane Library) were searched from the start of the research project to July 2018. Study selection, data extraction, and study quality assessment were independently carried out by two reviewers. The potentially identified randomized controlled trials (RCT) reported the useful quantitative data that were included only for meta-analysis.

RESULTS

meta-analysis of 17 medium-to-high quality RCTs showed significantly beneficial effects on HRV parameters (normalized low-frequency, Hedge's g = -0.39, 95% CI -0.39 to -0.56, < 0.001, I2 = 11.62%; normalized high-frequency, Hedge's g = 0.37, 95% CI 0.22 to -0.52, < 0.001, I2 = 0%; low-frequency to high-frequency ratio, Hedge's g = -0.58, 95% CI -0.81 to -0.35, < 0.001, I2 = 53.78%) and stress level (Hedge's g = -0.80, 95% CI -1.17 to -0.44, < 0.001, I2 = 68.54%).

CONCLUSIONS

Stress reduction may be attributed to sympathetic-vagal balance modulated by mind⁻body exercises. Tai Chi/Yoga could be an alternative method for stress reduction for people who live under high stress or negative emotions.

摘要

背景

心率变异性（HRV）作为一种准确、无创的自主神经系统（ANS）测量方法，能够反映心理健康状况（如压力、抑郁或焦虑）。太极拳和瑜伽（太极/瑜伽）作为最广泛练习的身心锻炼方式，已显示出对心理健康的积极影响。迄今为止，尚未有关于太极/瑜伽对HRV参数和感知压力的长期影响的系统综述。

目的

批判性地评估关于该主题的现有文献。

方法

从研究项目开始至2018年7月，检索了五个电子数据库（科学网、PubMed、Scopus、SportDiscus和Cochrane图书馆）。由两名评审员独立进行研究选择、数据提取和研究质量评估。潜在识别出的随机对照试验（RCT）报告了仅用于荟萃分析的有用定量数据。

结果

对17项中高质量RCT的荟萃分析显示，对HRV参数（归一化低频，Hedge's g = -0.39，95% CI -0.39至 -0.56，<0.001，I2 = 11.62%；归一化高频，Hedge's g = 0.37，95% CI 0.22至 -0.52，<0.001，I2 = 0%；低频与高频比值，Hedge's g = -0.58，95% CI -0.81至 -0.35，<0.001，I2 = 53.78%）和压力水平（Hedge's g = -0.80，95% CI -1.17至 -0.44，<0.001，I2 = 68.54%）有显著有益影响。
