“…To further substantiate the potential beneficial effect of prolonged Tai Chi/Yoga training for autonomic nervous function, a growing number of experimental studies have recently been conducted [ 27 , 28 , 29 , 30 , 31 , 32 , 33 ]. As the number of trials increases, two research groups attempted to systematically evaluate the existing literature regarding the effects of Tai Chi [ 34 ] or Yoga [ 35 ] on HRV. However, they either used qualitative synthesis [ 34 ] or meta-analyzed data about expiratory-to-inspiratory ratio, with inclusion of all age group and acute effects of yoga [ 35 ].…”

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, p < 0.001, I2 = 11.62%; normalized high-frequency, Hedge’s g = 0.37, 95% CI 0.22 to −0.52, p < 0.001, I2 = 0%; low-frequency to high-frequency ratio, Hedge’s g = −0.58, 95% CI −0.81 to −0.35, p < 0.001, I2 = 53.78%) and stress level (Hedge’s g = −0.80, 95% CI −1.17 to −0.44, p < 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.

“…Similarly, Christa E et al 4 observed in their study in frequency domain indices Our finding shows backward bending is superior to forward bending and should be included in lifestyle intervention to reduce stress and anxiety disorder; also reported by Chu I.H et al 5 in his study that a 12-week yoga program was effective in increasing parasympathetic tone and reducing depressive symptoms and perceived stress in women with elevated depressive symptom. Prevesioly Hewett ZL et al 6 found that a 16-week Bikram Yoga program did not increase the high-frequency power components of HRV.…”

Modulation of cardiac autonomic tone is a topic of current interest in research because of its association with several cardiovascular autonomic diseases of public health importance. Yoga has proven benefit in balancing the cardiac autonomic tone. This study aimed to explore the intricate mind body mechanisms with special reference to the immediate effect of Padahastasana (PD) and Ardha Chakrasana (AD) on cardiac autonomic nervous system and to quantify the cardiovascular ANS response to different yogic asana. Materials and Methods: This was a Cross Sectional Study, conducted in autonomic function lab, of

“…Many of the previous trials were conducted in healthy or normotensive populations [5][6][7][8][9][10][11][12][13][14], recruited participants from the workplace [9,11,15] or academic settings [8,10], and used the respective centres [8][9][10][11]14,16] or separate yoga studios [17][18][19] for the intervention. However, little evidence is available to demonstrate the impact of health-worker-led yoga interventions on blood pressure reduction in low-resource, primary care settings.…”

Background International guidelines for hypertension treatment recommend the use of yoga, particularly among low-risk patients. However, evidence is lacking on the implementation potential of health-worker-led yoga interventions in low-resource, primary care settings. Objective To assess barriers to and facilitators of the implementation of a yoga intervention for hypertensive patients in primary care in Nepal. Methods The study was conducted using focus group discussions, in-depth interviews, key informant interviews, and telephone interviews. Data were collected from the ‘Yoga and Hypertension’ (YoH) trial participants, YoH intervention implementers, and officials from the Ministry of Health and Population in Nepal. Results Most YoH trial participants stated that: (1) it was easy to learn yoga during a five-day training period and practise it for three months at home; (2) practising yoga improved their health; and (3) group yoga sessions in a community centre would help them practise yoga more regularly. Most YoH intervention implementers stated that: (1) they were highly motivated to implement the intervention; (2) the cost of implementation was acceptable; (3) they did not need additional staff to effectively implement the intervention; (4) providing remuneration to the staff involved in the intervention would increase their motivation; and (5) the yoga programme was ‘simple and easy to follow’ and ‘easily performed by participants of any age’. The government officials stated that: (1) yoga is considered as a key health promotional activity in Nepal; and (2) the integration of the yoga intervention into the existing health care programme would not be too challenging, because the existing personnel and other resources can be utilised. Conclusion While there is a good potential that a yoga intervention can be implemented in primary care, capacity development for health workers and the involvement of community yoga centres in the delivery of the interventions may be required to facilitate this implementation.
