“…BPV could be reduced also through corrections of lifestyle factors, like heavy alcohol use, or of clinical conditions, like obstructive sleep apnoea [169,170], or by implementing regular physical exercise or meditation [171,172,173]. Table S3, Supplemental Digital Content, http://links.lww.com/HJH/C121 provides a list of studies investigating the effects on BPV by different drugs.…”

Blood pressure is not a static parameter, but rather undergoes continuous fluctuations over time, as a result of the interaction between environmental and behavioural factors on one side and intrinsic cardiovascular regulatory mechanisms on the other side. Increased blood pressure variability (BPV) may indicate an impaired cardiovascular regulation and may represent a cardiovascular risk factor itself, having been associated with increased all-cause and cardiovascular mortality, stroke, coronary artery disease, heart failure, end-stage renal disease, and dementia incidence. Nonetheless, BPV was considered only a research issue in previous hypertension management guidelines, because the available evidence on its clinical relevance presents several gaps and is based on heterogeneous studies with limited standardization of methods for BPV assessment. The aim of this position paper, with contributions from members of the European Society of Hypertension Working Group on Blood Pressure Monitoring and Cardiovascular Variability and from a number of international experts, is to summarize the available

“…Typically, yoga practitioners have been compared to nonpractitioners in the parasympathetic activity studies. In one study, for example, 40 yoga practitioners were compared with 40 nonpractitioners [56]. The practitioners were noted to have lower heart rate and greater heart rate variability in a supine resting position.…”

Yoga Therapy Research: A Narrative Review

2023

Curr Res Cmpl Alt Med

This narrative review on yoga therapy research that was published during the years 2020 to 2023 includes 58 papers. The publications of this period are primarily systematic reviews and meta-analyses of randomized controlled trials. Many of these (15%) are focused on yoga reducing anxiety and depression during pregnancy. Pediatric research has included yoga for motor and cognitive performance in youth and adult research has been focused on yoga for depression, migraines, diabetes and cancer. Surprisingly, studies on older adults including yoga for cognitive dysfunction and for Parkinson's comprise a significant number of the yoga publications (18%). Other studies include comparisons of Tele-yoga and in-person yoga and different yoga styles. Underlying mechanism research suggests that increased parasympathetic activity occurs following yoga as well as a reduction in cortisol and pro-inflammatory cytokines. Methodological problems continue to relate to the combined assessment of multiple yoga styles and their differing intensity and the more frequent measurement of psychological versus physical effects, although the mechanism studies highlight the positive physical effects of yoga.This narrative review involved entering the terms yoga and the years 2020-2023 into PubMed and PsycINFO. The search yielded 349 papers for the last four years. However, following exclusion criteria, including case studies, non-English papers and study protocols, this review is a summary of the research reported in 58 papers. The recent literature on yoga is predominantly focused on the reduction of anxiety and depression during pregnancy and on improving cognitive function in older adults including those with Parkinson's. Other research involves yoga for youth for motor skills and cognitive performance and for adults to reduce depression, migraines and cancer symptoms as well as historical trends in the research and comparisons of different yoga styles including traditional yoga, exercise yoga and restorative yoga. This narrative review is accordingly divided into sections on research trends, comparisons of yoga styles, different age groups and conditions, potential underlying biological mechanisms and methodological limitations. Research TrendsIn a paper entitled "A PubMed-based exploration of the course of yoga research 1948 to 2020" different types of yoga research are given for each of several time periods [1]. One per cent of the yoga research from 1948 to 2020 occurred during the period 1948 to 1970 and was focused on the exceptional abilities of yoga practitioners. Seven percent of the research was published during the years 1971 to 2000 and was focused on health and therapy. Ninety-two percent of the research was published during the subsequent years 2001 to 2020 and was focused also on health and therapy but with fewer randomized controlled trials compared to systematic reviews and meta-analyses. More specifically from 1981 to 1990 the health and therapy articles were primarily on asthma, stress and diabetes. In the period 1991 to...

Background: COVID-19 pandemic posed a huge stress on health-care givers affecting their physical and mental health. Wellness strategies like yoga can improve flexibility, resilience, and outlook. Aim: The present study explored the effect of 8-week standard common yoga protocol (CYP) intervention on autonomic functions, emotional stress, oxidative stress, and inflammation markers in the nurse group of health-care givers. Materials and Methods: It is a randomized controlled trial where 50 nurses underwent CYP and 50 participated as controls. Anthropometric parameters, cardiovascular parameters, autonomic function including time and frequency domain parameters, biochemical parameters, and psychological stress using the questionnaire were assessed before and after 8-week CYP. Results: Total 88 nurses completed the study with 42 and 46 participants, respectively, in the CYP and control groups. CYP intervention resulted in a significant reduction in cardiovascular parameters systolic blood pressure, diastolic blood pressure, mean arterial pressure, pulse pressure, and rate pressure product (P < 0.001, P < 0.001, P < 0.001, P < 0.001, and P = 0.002, respectively), perceived stress score and Depression, Anxiety, and Stress Scale psychological variables of depression, anxiety, and stress, and serum lipid parameters compared to the control group. CYP significantly increased total power, low frequency, high frequency, root mean square of successive differences between adjacent NN intervals, change in successive normal sinus (NN) intervals exceeds 50 ms, and pNN50% (P < 0.001, P = 0.006, P = 0.006, P = 0.039, P < 0.001, and P = 0.013, respectively) suggesting improved resting autonomic modulation and parasympathodominance due to higher vagal efferent activity. There were significant reductions in serum cortisol, tumor necrosis factor-alpha, interleukin (IL)-1, and IL-6 in both the groups. Serum telomerase significantly reduced (P = 0.024) and total antioxidant capacity (P = 0.036) increased in the CYP group post intervention. Conclusion: CYP intervention was beneficial in improving psychophysiological, autonomic, and biochemical profile of the nurse group of health-care workers.
