Eight-week stress management exercise program improves mental health and autonomic nervous system of adults exposed to chronic stress

BACKGROUND

This study investigated a stress management exercise program's effect on mental health, muscle pain, and autonomic nervous system activity in adults exposed to chronic stress.

METHODS

Thirty mothers between 40 to 59 years old raising children with disabilities were equally allocated into the yoga (YG) or control group (CG). The YG participated in 16 prop-assisted yoga sessions twice weekly for eight weeks, focusing on relaxing and strengthening neck, shoulder, back, and waist stress-related muscles. The Beck Depression Inventory, State-Trait Anxiety Inventory, Parenting Stress Scale, Stress Response Inventory, and Brief Resilience Scale assessed mental health variable changes. Visual Analog Scales (VAS) were used to self-report neck, shoulders, back, and waist pain and assess stress, anxiety, relaxation, and confidence. We also measured pain, psychological VAS, and Heart Rate Variability (HRV) immediately before and after each yoga session.

RESULTS

The YG exhibited significant reductions in muscle pain, depression, stress response, fatigue, and frustration, whereas the CG expressed no change. Prop-assisted yoga immediately improved pain and psychological VAS. HRV analyses revealed instantly reduced heart rates and an R-R interval and standard deviation normal to normal (SDNN) increase.

CONCLUSIONS

Prop-assisted yoga may serve as a viable, safe, and efficient alternative therapeutic modality for managing chronic stress-related conditions.

Preliminary effects of a yoga intervention for lung cancer dyads: benefits for care partners

PURPOSE

Lung cancer is a disease with high mortality and morbidity, impacting both the patient and their closest contact, referred to in this paper as their care partner. There is limited evidence on how to support mental health and quality of life (QOL) for patient-care partner dyads during cancer treatment. This pilot study examines yoga as an intervention to improve well-being for the dyad.

METHODS

A single-group, 12-week pilot trial of yoga for patients and their care partners recruited from two hospitals during cancer treatment (N = 23 patient-partner dyads or 46 individuals). Most care partners were spouses (70%), with the remainder being adult children (22%), a sibling (4%), or a friend (4%). Descriptive statistics, Cohen's d effect sizes, and paired t-tests for validated psychosocial measures were calculated at baseline and 12 weeks.

RESULTS

Sixty-five percent of dyads (N = 13) completed the study, with withdrawals mostly due to disease progression. Among care partners, there was a decrease in depression symptomology on the PHQ-8 (p = 0.015, Cohen's d = 0.96) and improvement in QOL on the Caregiver QOL-Cancer scale (p = 0.001, Cohen's d = 0.61). Fifty percent of dyads experienced concordant improvement in depressive symptoms and 77% in QOL.

CONCLUSION

Patient-partner yoga is a promising intervention for improving mental health and QOL for patient-partner dyads among lung cancer survivors. This study demonstrates yoga to be acceptable, feasible, and with high concordance within patient-partner dyads for improvements in QOL. Yoga shows promise for patients and care partners to alleviate the negative psychosocial impacts of lung cancer, though more research is needed to confirm effects.

Effects of a Yoga Program Combined with a Mediterranean Diet on Nutritional Status and Functional Capacity in Community-Dwelling Older Adults: A Randomized Controlled Clinical Trial

(1) Background: With the aging population, effective interventions are needed to enhance the health of older adults. This study investigated the combined effects of yoga and the Mediterranean diet on various health outcomes in community-dwelling older adults; (2) Methods: The study employed a randomized controlled trial design with a total of 116 older adults randomized to an experimental group (n = 57) that underwent a combined yoga and Mediterranean diet program and a control group (n = 59) that did not receive any intervention. Nutritional status was assessed using the Mini Nutritional Assessment, flexibility with the Back Scratch Test and the Chair Sit-and-Reach Test, balance, gait, and fall risk with the Tinetti Scale, and muscle strength with a dynamometer and the 30 s Chair Stand Test; (3) Results: Regarding nutritional status, there were significant differences between the experimental group and the control group (Cohen's d = 0.02). The participants in the experimental group showed greater balance (11.12 ± 3.01 vs. 10.03 ± 2.35, Cohen's d = 0.41 and gait (7.63 ± 1.96 vs. 6.69 ± 2.50, Cohen's d = 0.44) with respect to the control group. In terms of flexibility, the experimental group showed statistically significant improvements in the right arm (Cohen's d = 0.43), left arm (Cohen's d = 0.64), right perineum (Cohen's d = 0.42), and left leg (Cohen's d = 0.37) Finally, in terms of strength, participants in the experimental group experienced statistically significant improvements in grip strength and lower body strength (Cohen's d = 0.39 and 0.81, respectively); (4) Conclusions: The study highlights the potential benefits of a 12-week intervention combining yoga with a Mediterranean diet to improve the health and functional capacities of community-dwelling older adults.

An Intervention to Improve Mental and Physical Health of Undergraduate Nursing Students

BACKGROUND

Nursing students experience poorer mental and physical health relative to students in other health-related disciplines and young adults of similar age outside post-secondary school. Compromised mental and physical health has numerous negative impacts on nursing students and can result in burnout and development of chronic diseases.

PURPOSE

To determine whether an asynchronous online yoga intervention would improve mental and physical health of students.

METHODS

An asynchronous online 6-week yoga intervention was carried out between January and December 2021, using a pre/post design. Participants' symptoms of depression, anxiety, stress, and self-compassion were assessed using the Depression, Anxiety, and Stress Scale and Self-Compassion Scale and core endurance was assessed using the Mackenzie Core Endurance Test prior to commencement and at the conclusion of the program.

RESULTS

Of 114 participants, 68 completed the online program and pre and post measures showed that the mean depression, anxiety, stress, self-compassion and core endurance scores improved significantly (p<0.001) between baseline and study completion.

CONCLUSION

A six-week virtual yoga program significantly improved mental and physical health of undergraduate nursing students. Targeted modifications to the yoga program might enhance participant retention.

Perceived delivery of essential yoga properties within in-person and remote weight loss maintenance interventions

OBJECTIVES

While previous research has utilized remote delivery of yoga interventions, no research has specifically interrogated the effectiveness of remote yoga intervention delivery. In this secondary analysis of weight-maintenance trial data, we examined participant perceptions of essential yoga properties across in-person and remote formats, hypothesizing that perceptions would not differ following remote delivery.

METHODS

24 women with overweight or obesity (34.6±4.1 kg/m2, 48.2±9.9 years) received a 12-week Iyengar yoga intervention (2x/week) following a 3-month behavioral weight loss program. Of 23 participants who completed follow-up questionnaires, 12 received the planned in-person intervention and 11 received a remote intervention (delivered live) due to the COVID-19 pandemic. The Essential Properties of Yoga Questionnaire (EPYQ) was completed online by participants and by the instructors to measure the perceptions of the relative emphasis placed on the essential components of the yoga intervention via 14 subscales. Linear regression models were used to compare perceptions of each EPYQ dimension across in-person and remote delivery methods, as well as between participants and instructors, independent of delivery method.

RESULTS

13 of the 14 subscales did not differ between delivery modalities (p>0.05). Participants perceived more individual attention within in-person yoga (p = 0.003). For both delivery methods, instructors perceived breathwork, restorative postures, and body locks to be incorporated to a lesser degree compared to participants (β = -1.28, p = 0.003; β = -1.57, p = 0.019; β = -1.39, p = 0.036; respectively). No other significant differences across the participant and instructor scores were observed.

CONCLUSIONS

Findings provide preliminary support for the use of live remote delivery of yoga, effectively communicating most essential yoga properties when compared to in-person classes. However, participants perceived more individual attention with in-person versus remote delivery; thus, future remote-based yoga interventions may benefit from providing additional individualized feedback.

Exploring the Impact of a Trauma-informed Yoga and Mindfulness Curriculum for Multiple Populations: A Pilot Study

Individuals with trauma experience negative mental health impacts and are at risk of poor cardiovascular outcomes. Unmanaged, these conditions may worsen, compromising healing and wellbeing. Yoga, particularly trauma-informed, may improve outcomes. The current pilot study explores the impact of a novel trauma-informed yoga and mindfulness curriculum on wellbeing in two parts. The first examined mental health (stress, mood) outcomes in four trauma-impacted populations: adults who were incarcerated (INC), individuals in recovery from substance use disorders (SU), veterans (VA), and vulnerable youth (YTH) assessing both the impact of individual class participation and impact of attending at least four curriculum sessions. For the subgroup of incarcerated individuals, impact by theme was examined. After curriculum sessions, stress was reduced, and mood improved. Across multiple sessions both the largest decreases in stress and greatest increase in mood occurred after participant in the first session. Further, a specific exploration of curriculum class impact by theme for participants who were incarcerated indicated no difference in impact by theme. The second part of this study explored cardiovascular outcomes for the population of those in recovery from substance use. Reductions in systolic blood pressure occurred immediately after the first curriculum session, and diastolic blood pressure reduced over three consecutive sessions.

Application of mobility training methods in sporting populations: A systematic review of performance adaptations

This systematic review investigates influences of mobility training in sporting populations on performance outcomes. The search strategy involved Embase, MEDLINE Complete, Sports Discus and manual search from inception to March 2022. Mobility training studies with a minimum three-week, or 10-session duration in healthy sporting populations of any age were included. Twenty-two studies comprising predominantly young adult or junior athletes were analysed from 319 retrieved articles. Performance outcomes were strength, speed, change of direction, jumping, balance, and sport-specific skills. Fifteen studies randomized participants with only four indicating systematic allocation concealment and blinding of outcomes assessors in only one study. In 20 of 22 studies mobility training was of some benefit or helped to maintain sports performance to a larger degree than control conditions. Control conditions, which were generally no activity conditions, were primarily non-significant. The majority of evidence suggests that a range of mobility training methods may improve key sports performance variables or are unlikely to impair performance over time. Therefore, coaches can consider the potential benefits of including comprehensive mobility programmes with minimal risk of impairing performance. Higher-quality studies in homogenous populations are necessary to confirm performance changes.

Effect of tele-yoga on aerobic capacity, respiratory muscle strength, and cognitive performance in patients with obstructive sleep apnea syndrome

BACKGROUND

Obstructive sleep apnea syndrome (OSAS) causes a decrease in aerobic capacity, respiratory muscle strength, and cognitive function, negatively affecting health-related quality of life.

OBJECTIVES

This study aimed to compare aerobic capacity, respiratory muscle strength, cognitive performance, functional capacity, sleep quality and daytime sleepiness in OSAS patients practicing and not practicing tele-yoga (TY).

METHODS

44 OSAS patients (40 M, 4F) were randomized into TY and control groups. TY group underwent live synchronous group-based TY sessions, 60 min/day, three days/week, for 12 weeks. Control group performed unsupervised thoracic expansion exercises at home 4 times daily for 12 weeks. The following were evaluated at baseline and at the end of the 6th and 12th weeks: inspiratory and expiratory respiratory muscle strength (MIP, MEP), cardiopulmonary exercise test, Corsi Block Tapping Test (CBTT) and Stroop TBAG test, six-minute walk test (6MWT), Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS).

RESULTS

TY significantly improved MIP, and exercise test parameters (VE, HRmax,%HR, heart rate recovery in the first minute and RQmax), CBTT (forward) and Stroop TBAG test scores (parts of 3,4,5) compared to the controls (p<0.05). There were no significant changes 6MWT in the TY group compared to the control group (p > 0.05). Sleep duration (min), sleep efficiency, sleep quality of PSQI and ESS score improved significantly in the TY group compared to the control group (p < 0.05).

CONCLUSION

We suggest including TY intervention as a method of exercise in addition to CPAP treatments since it improves the health-related parameters of OSAS patients.

Effect of yoga on adipokine levels among overweight and obese people: A systematic review

BACKGROUND

Adipokines have an important role in the pathophysiology of overweight and obesity and associated inflammatory diseases.

OBJECTIVE

The present review aims to evaluate the role of Yoga on adipokines among people with overweight and obesity.

METHODS

Authors performed a systematic search for relevant research studies as per the PRISMA guidelines in Google Scholar, Medline/Pubmed, Scopus, Web of Science, PsychInfo electronic databases. Two independent authors conducted the selection of articles, data extraction, assessment of the risk of bias for individual studies. Any disagreements were resolved by discussion with the third author.

RESULTS

Eight randomized trials and four uncontrolled trials involving a total of 1054 participants were included. Yoga with varying frequencies was administered for different durations. The studied adipokines among overweight and obese were leptin, adiponectin, interleukin-6 (IL-6), Tumor necrosis factor-alpha (TNF-α), chemerin, visfatin, plasminogen activator inhibitor-1 (PAI-1), and transforming growth factor-beta (TGF-β). The methodological quality of the included studies was low to moderate on the Cochrane risk of bias tool and Newcastle-Ottawa Quality Assessment Scale. The higher the frequency and duration of Yoga practice, the more significant changes in the adipokine levels were seen.

CONCLUSION

The present review indicates that Yoga practices positively impacts adipokines among people with overweight and obesity. However, the present study precludes the generalizability of results due to the methodological heterogeneity, the type of Yoga intervention, and settings.

Recommending yoga for health: A survey of perceptions among healthcare practitioners in the UK

BACKGROUND

Yoga has the potential to support patients across various health conditions. It is slowly being integrated into healthcare worldwide. While healthcare practitioners (HCPs) are critical to integration, there are currently no studies investigating their perceptions of yoga for health, their openness to recommending yoga to patients, and barriers to doing so. This novel UK study aims to address this.

METHOD

An online survey was conducted among practising UK HCPs. Recruitment was through multi-modal convenience sampling. The COM-B model was used as a framework. Regression analysis examined predictors of HCPs' likelihood to recommend yoga. Open-end responses were analysed through thematic analysis.

RESULTS

198 HCPs were included in the analysis, including general practitioners (GPs, 18.8%), psychologists (18.3%), and nurses/health visitors (14.7%). A high proportion (68.8%) practised yoga at least monthly. The likelihood of recommending yoga to patients was high (M = 4.03, SD = 0.94; 5-point scale). Older age, not being a GP, and greater capability and motivation significantly predicted a greater likelihood of recommending yoga, explaining 41.4% of the variance (p < 0.001). Barriers to recommending yoga were mostly related to the lack of opportunity.

CONCLUSIONS

HCPs in this study had high levels of personal engagement with yoga and were open to recommending yoga to patients, but still faced several barriers. Workplace support, particularly for GPs, and information about how patients can access appropriate and affordable yoga instruction would facilitate referral. Further research with a representative sample is warranted to understand perceptions of HCPs less engaged with yoga.

Increased Effect Sizes in a Mindfulness- and Yoga-Based Intervention After Adjusting for Response Shift with Then-Test

Objectives

Response shift refers to variations in self-reported evaluations at different times from changes in one’s internal standards, values, and meanings. The current study explored the utility of the then-test to detect a potential mindfulness-based response shift occurrence during a mindfulness- and yoga-based intervention for student musicians, and to ascertain to what extent effect sizes could differ when adjusting for it.

Method

Participants (n = 31) completed the Five Facet Mindfulness Questionnaire (FFMQ) halfway through the intervention (Time 1-FFMQ), post-intervention (Time 2-FFMQ), and immediately after Time 2-FFMQ with a then-test approach that asked participants to rate the FFMQ based on retrospective reflections on their mindfulness at Time 1 (then-test-FFMQ). Paired t-tests and Hedges’ g effect sizes were computed to estimate three potential effects: response shift (Time 1-FFMQ minus then-test-FFMQ), the conventional intervention effect (Time 2-FFMQ minus Time 1-FFMQ), and the effect after adjusting for response shift (i.e., actual intervention effect = Time 2-FFMQ minus then-test-FFMQ).

Results

Response shift was significant for the FFMQ Observe subscale (g = 0.41) and total scale (g = 0.37). The adjusted scores in all subscales (Observe, g = 0.47; Describe, g = 0.25; Act Aware, g = 0.40; Non-judge, g = 0.28; Non-react, g = 0.57) and total scale (g = 0.60) achieved significance and yielded larger effect sizes than the conventional results, for which only Act Aware (g = 0.28), Non-react (g = 0.36), and total scale (g = 0.28) were significant.

Conclusions

Notwithstanding some methodological limitations, this study lends support to the utility of the then-test to quantify response shift. When adjusting for it, effect sizes from a mindfulness- and yoga-based intervention were generally amplified.

Going within, between and beyond: An exploration of regular Ashtanga Yoga practitioners' conceptualizations of five dimensions of wellbeing

Yoga is an embodied practice underpinned by philosophical elements, seeking to evolve different dimensions of human existence for optimal functioning in relation to oneself, others and beyond. This mixed-methods research focused on 137 regular Ashtanga Yoga practitioners (AYPs) by investigating their conceptualizations of five dimensions of wellbeing (i.e., physical, emotional, psychological, social, spiritual). Conceptualizations were analysed through word count analysis and Reflexive Thematic Analysis separately for each dimension, yielding four themes in each case, which partly aligned with existing wellbeing and yoga models, and partly extended on the existing literature. Further higher level analysis identified shared meanings across these five dimensions, expressed in themes grouped within five topics (i.e., freedom from and managing suffering, a positive and integrated sense of self, a sense of equanimity and steadiness, the self in relation to others and the world, meta-awareness). Furthermore, it also portrayed each dimension as multileveled, represented in three levels of human functioning. The foundational level encompassed the absence and managing suffering, representing functioning in coping and recovery mode. The optimal functioning level included a positive and integrated sense of self, a sense of equanimity and steadiness, and the self in relation to others and the world, representing functioning in personal development and growth mode. The contemplative and transcendental level involved meta-awareness in every dimension of wellbeing, representing functioning in transpersonal mode. As a result, we propose a preliminary model informed both by this empirical work and previous theories. While the continuousness of themes across dimensions reinforces the importance of embodiment and transcendence in wellbeing frameworks, the notion of the self as a multi-level system could be further explored in relation to knowing about and cultivating wellbeing.

Physical exercise interventions for perinatal depression symptoms in women: A systematic review and meta-analysis

Background

The previous meta-analysis indicated that physical exercise could play a crucially therapeutic role in reducing perinatal depression symptoms in women. However, the efficacy varies across different exercise types, forms, intensities, and duration.

Aim

The purpose of this study was to review and evaluate the effects of different types, forms, intensities, and duration of exercise for improving perinatal depressive symptoms.

Design

A systematic review and meta-analysis.

Methods

Randomized controlled trials until December 2021 were searched from seven databases, including PubMed, EMBASE, Medline, CINAHL, Web of Science, Cochrane Library, and PsycINFO. The risk of bias in eligible trials was evaluated using the Cochrane Risk of Bias tool. When high heterogeneity was tested, we used random-effects models. A funnel plot was used to assess the publication bias. This review was performed under the PRISMA guidelines, Consensus on Exercise Reporting (CERT) checklist and Cochrane Handbook. The certainty of the body of evidence was assessed using the GRADE method.

Results

Of 1,573 records, 20 trials were identified in this study. The results of this review revealed that women with perinatal depression symptoms gained benefits from physical exercise [OR = 0.62, 95% CI (0.45, 0.86), P = 0.004; MD = -0.57, 95% CI (-0.83, -0.30), P < 0.0001]. Type of walking [SMD = -1.06, 95% CI (-1.92, -0.19), P < 0.00001], form of "Individual + group-based"exercise [SMD = -0.91, 95% CI (-0.80, -0.03), P = 0.04], intensity of ≥150 min per week [SMD = -0.84, 95% CI (-1.53, -0.15), P = 0.02], and ≥12 weeks duration [SMD = -0.53, 95% CI (-0.75, -0.31), P < 0.00001] seemed to generate more prominent improvement on perinatal depression symptoms.

Conclusion

Physical exercise showed a significant effect on reducing perinatal depressive symptoms. This meta-analysis provides an important update on exercise's efficacy in treating perinatal depression. Further higher quality and large-scale trials are needed to substantiate our findings.

Bibliometric and visualized analysis of exercise and osteoporosis from 2002 to 2021

Background

Bibliometric analysis was designed to investigate a systematic understanding of developments in exercise and osteoporosis research over the past 20 years.

Methods

Relevant publications from the Web of Science Core Collection were downloaded on April 26, 2022. CiteSpace, VOSviewer, and the online bibliometric analysis platform were used to conduct this scientometric study.

Results

A total of 5518 publications were in 1202 academic journals with 137405 co-cited references in by 5637 institutions from 98 countries/regions. The country leading the research was the USA. The University of Melbourne was the most active institution. Osteoporosis International was the most productive journal concerning exercise and osteoporosis research. According to the burst references, "low-level vibration," "high-frequency" and "resistance exercise" have been recognized as the hotspots research in the domain. The keywords co-occurrence analysis identified "skeletal muscle," "sarcopenia" and "mesenchymal stem cell" as the important future research directions.

Conclusion

This study was the first comprehensive metrological and statistical analysis of exercise and osteoporosis research over the past 20 years. Our findings would provide guidance to understand the research frontiers and hot directions in the near future.

Effects of vibrotactile feedback on yoga practice

Participating in physical exercise using remote platforms is challenging for people with vision impairment due to their lack of vision. Thus, there is a need to provide nonvisual feedback to this population to improve the performance and safety of remote exercise. In this study, the effects of different nonvisual types of feedback (verbal, vibrotactile, and combined verbal and vibrotactile) for movement correction were tested with 22 participants with normal vision to investigate the feasibility of the feedback system and pilot tested with four participants with impaired vision. The study with normal-vision participants found that nonvisual feedback successfully corrected an additional 11.2% of movements compared to the no-feedback condition. Vibrotactile feedback was the most time-efficient among other types of feedback in correcting poses. Participants with normal vision rated multimodal feedback as the most strongly preferred modality. In a pilot test, participants with impaired vision also showed a similar trend. Overall, the study found providing vibrotactile (or multimodal) feedback during physical exercise to be an effective way of improving exercise performance. Implications for future training platform development with vibrotactile or multimodal feedback for people with impaired vision are discussed.

Yoga Module Development and Validation: A Systematic Review with Methodological Guidelines

In the past decades, more than fifty different yoga styles have been implemented in the therapeutic context to manage various diseases. Yet, not all of these yoga styles have been validated or standardized as a program. The aim of this article is to review the different methodologies used for yoga module development and to assess their quality. Three databases (PubMed, Web of Science, and Scopus) were searched using the following keywords and Boolean operators: (validation OR development OR design) AND (yoga OR mind-body) AND (module OR protocol OR program). Three thousand six hundred and seventy-one articles were enlisted, and based on the inclusion and exclusion criteria, 37 articles were narrowed down for review. Since no checklist exists to assess the quality of yoga modules, the authors designed a 23-item checklist to categorize each having low, medium, or high quality. As per the yoga module quality checklist, only 21.6% of the studies had high quality, while 75.3% of the articles had medium quality and 8.11% had low quality. A commonly used development method was literature review, while for validation, experts' scoring of the Likert scale was the preferred means. The feasibility of the module was carried out only by half of the studies. Few diseases such as cardiovascular disease, diabetes mellitus, obesity, Parkinson's disease, and obesity had more than one yoga module developed. The findings of this systematic review have shed some light on the growing need for standardized methods of yoga module development. The 23-item checklist can guide researchers in the homogeneous development strategies when designing yoga interventions in the future.

Analysis of Retinal Blood Vessel Diameters in Pregnant Women Practicing Yoga: A Feasibility Study

Studies have shown that practicing yoga during pregnancy beneficially affects maternal and neonatal outcomes. The objective of this study was to determine the effect of prenatal yoga on the microvascular circulatory system via non-invasive measurements of retinal blood vessels. We included 29 women who practiced prenatal yoga in the study. There were no statistically significant differences in arteriolar and venular diameters pre- vs. post-90 min yoga practice (150.5 ± 11.4 μm pre- vs. 151.2 ± 10.2 μm post-yoga; p = 0.53 for arteriolar and 221.8 ± 16.1 μm pre- vs. 223.2 ± 15.7 μm post-yoga; p = 0.51 for venular diameters). The current study demonstrated the feasibility of the setup. More extensive studies are needed to determine the potential microvascular effects of practicing yoga throughout pregnancy.

Yoga and Qigong for Health: Two Sides of the Same Coin?

Yoga and qigong are ancient mind–body practices used in the East for thousands of years to promote inner peace and mental clarity. Both share breathing techniques and slow movements and are being used as alternative/complementary approaches to the management of disease, especially chronic problems with no effective conventional treatments. However, information comparing the health benefits of both approaches is scarce, and the choice between yoga or qigong practice may only depend on patients’ preferences or practice availability. The aim of the present paper was to overview yoga and qigong use for health benefits under different pathological conditions. Yoga and qigong seem to have similar effects, which might be expected, since both are similar mind–body approaches with the same concept of vital life-force energy and the practice of meditative movements. Problematic research issues within the literature on yoga and qigong are the small sample sizes, use of different styles, significant variance in practice duration and frequency, short duration of intervention effects, and the usage of a non-active control group, thus emphasizing the need for further high-quality randomized trials. Studies comparing yoga and qigong are warranted in order to assess differences/similarities between the two approaches for health benefits.

Methodological issues in conducting yoga- and meditation-based research: A narrative review and research implications

Yoga and meditation-based interventions have been extensively utilized in the field of contemporary complementary and alternative medicine for various physical and mental health conditions. Ongoing COVID-19 pandemic has rekindled the interest of researchers in yoga and meditation for its preventive and therapeutic utilities. However, the available literature in this area has several methodological concerns, limiting formers’ clinical utility. A comprehensive literature on this topic would stimulate researchers and guide them to conduct research on this topic with robust methodologies. The current review highlights the methodological issues with the yoga and meditation-based Research (henceforth, MBR), discusses some of the contentious issues, and provides future directions. The PubMed, Medline, and google scholar databases were searched to screen records dealing with the methodological issues on MBR. The search yielded 299 records, upon screening, only 24 articles were found suitable for the current study. Common methodological issues with MBR: lack of the consensus definitions of the yoga and meditations, interventions lacking theoretical framework of meditation; inadequate description of the study design; difficulty with participants recruitment, setting up the control groups, and blinding; difficulty in assessing the baseline characteristics of the participants, and validity issues with the outcome measures. A few research, however, have also highlighted the potential measures to overcome these methodological challenges. Yoga and meditation-based interventions are promising for several health conditions. However, literature suffers from considerable methodological issues, thus, limiting its utility in modern clinical practice. The study findings can stimulate and guide future research on this topic.

Hot Yoga Leads to Greater Well-being: A Six-week Experience-sampling RCT in Healthy Adults

Practicing hot yoga may bring significant psychological benefits, but it is largely unstudied. We examined the effects of hot yoga on multifaceted well-being indicators with 290 healthy yoga-naïve volunteers partaking in a six-week randomized controlled trial. Participants completed questionnaires pre- and post-intervention, and reported their emotional experiences four times per day throughout an experience-sampling study. Results revealed that the hot yoga group (n = 137) improved their well-being from pre- to post-treatment, comparing to the wait-list control group (n = 153). These improvements included life satisfaction, general health, mindfulness, peace of mind, and eudaimonic well-being (ΔR² ranging from .01 to .08)-but not flourishing, which describes major aspects of social-psychological functioning. Multilevel analyses demonstrated that momentary positive emotional experiences increased significantly throughout the trial in the yoga group only (conditional R² = .68), particularly when attending a yoga class (conditional R² = .50). Interestingly, this increase in momentary positive emotion explained the improvement in post-intervention mindfulness, peace of mind, and general health by 21%, 31%, and 11%, respectively. Finally, the benefits of hot yoga were more notable in individuals with lower levels of baseline eudaimonic well-being (conditional R² = .45), flourishing (conditional R² = .61), and mental well-being (conditional R² = .65), even after ruling out any possible ceiling effects. To sum up, this study demonstrated multiple psychological benefits of hot yoga and its potential to be an effective positive psychology intervention. Future research-especially considering an active control group-is warranted.

Integration of hatha yoga and evidence-based psychological treatments for common mental disorders: An evidence map

BACKGROUND

Interest in the use of yoga to enhance engagement with and augment the benefits of psychological treatment has grown. However, a systematic approach to reviewing existing research examining the use of yoga with psychological treatment is lacking.

MATERIALS AND METHODS

This mapping review identified and synthesised research trialling yoga as an integrated or adjunct therapy with evidence-based psychological interventions for the treatment of anxiety, depression, PTSD, and eating disorders.

RESULTS

Overall, the review identified ten published and three unpublished studies, representing either single group or small quasi-experimental research designs.

DISCUSSION

Limited but promising findings were shown for yoga with CBT for anxiety and depression, and the integration of yoga within intensive treatment models for PTSD.

CONCLUSIONS

Future research is encouraged to focus on controlled trials that enable examination of the component effect of yoga when applied with evidence-based psychological treatment and acceptability and feasibility data to further knowledge regarding a role for yoga in clinical practice.

When Eastern Meets Western Medicine to Manage SARS-CoV-2/COVID-19 Patient: a Case Report

Psychological and psychosocial issues are one of the prime areas to be focused on in SARS-CoV-2/COVID-19. However, those patients' mental, social, and emotional parts are still not being focused on while treating the SARS-CoV-2/COVID-19. Thus, we integrated both eastern and western medicine to discuss its impact on the mental and psychological issues of the patient. We treated a 52-year-old man who was infected with COVID-19/SARS-CoV-2 and had a sign and symptoms of fever, sore throat, running nose, cough, and tiredness. The patient was treated with integrated medicine, where we combined both eastern and western medicine to treat all aspects of health, i.e., physical, mental, emotional, and social. With the intervention we applied, his health was getting better day by day, and on the 16th day, his SARS-CoV-2 came negative. In addition, his mental health was also much better than the initial days of intervention. The integrated medicine therapeutic strategy effectively treats COVID-19 patients in all dimensions of health.

A systematic review of in vivo stretching regimens on inflammation and its relevance to translational yoga research

OBJECTIVE

To conduct a systematic review evaluating the impact of stretching on inflammation and its resolution using in vivo rodent models. Findings are evaluated for their potential to inform the design of clinical yoga studies to assess the impact of yogic stretching on inflammation and health.

METHODS

Studies were identified using four databases. Eligible publications included English original peer-reviewed articles between 1900-May 2020. Studies included those investigating the effect of different stretching techniques administered to a whole rodent model and evaluating at least one inflammatory outcome. Studies stretching the musculoskeletal and integumentary systems were considered. Two reviewers removed duplicates, screened abstracts, conducted full-text reviews, and assessed methodological quality.

RESULTS

Of 766 studies identified, 25 were included for synthesis. Seven (28%) studies had a high risk of bias in 3 out of 10 criteria. Experimental stretching protocols resulted in a continuum of inflammatory responses with therapeutic and injurious effects, which varied with a combination of three stretching parameters--duration, frequency, and intensity. Relative to injurious stretching, therapeutic stretching featured longer-term stretching protocols. Evidence of pro- and mixed-inflammatory effects of stretching was found in 16 muscle studies. Evidence of pro-, anti-, and mixed-inflammatory effects was found in nine longer-term stretching studies of the integumentary system.

CONCLUSION

Despite the overall high quality of these summarized studies, evaluation of stretching protocols paralleling yogic stretching is limited. Both injurious and therapeutic stretching induce aspects of inflammatory responses that varied among the different stretching protocols. Inflammatory markers, such as cytokines, are potential outcomes to consider in clinical yoga studies. Future translational research evaluating therapeutic benefits should consider in vitro studies, active vs. passive stretching, shorter-term vs. longer-term interventions, systemic vs. local effects of stretching, animal models resembling human anatomy, control and estimation of non-specific stresses, development of in vivo self-stretching paradigms targeting myofascial tissues, and in vivo models accounting for gross musculoskeletal posture.

Effect of Trataka (Yogic Visual Concentration) on the Performance in the Corsi-Block Tapping Task: A Repeated Measures Study

Background and Objective: Attention and memory are essential aspects of cognitive health. Yogasanas, pranayama, and meditation have shown to improve cognitive functions. There has been no assessment of Trataka (yogic visual concentration) on working or on spatial memory. The present study was planned to assess the immediate effects of Trataka and of eye exercise sessions on the Corsi-block tapping task (CBTT). Methods: A total of 41 healthy volunteers of both genders with age 23.21 ± 2.81 years were recruited. All participants underwent baseline assessment, followed by 2 weeks of training in Trataka (including eye exercise). Each training session lasted for 20 min/day for 6 days a week. After completion of the training period, a 1-week washout period was given. Each participant then was assessed in two sessions in Trataka and in eye exercise on two separate days, maintaining the same time of the day. Repeated measure analysis of variance with Holm's adjustment was performed to check the difference between the sessions. Results: Significant within-subjects effects were observed for forward Corsi span andforward total score (p < 0.001), and also for backward Corsi span (p < 0.05) and backward total score (p < 0.05). Post hoc analyses revealed Trataka session to be better than eye exercises and baseline. The eye exercise session did not show any significant changes in the CBTT. Conclusion: The result suggests that Trataka session improves working memory, spatial memory, and spatial attention.

Practice or performance? A content analysis of yoga-related videos on Instagram

Representations of yoga within media have become increasingly idealised, depicting typical practitioners as young, thin, and physically competent. While previous content analyses of yoga have focused on still images, social media platforms such as Instagram encourage the use of video to enhance viewer engagement. Video may contain features which reflect a more nuanced view of the body, and therefore the current study analysed 400 women in yoga-related videos on Instagram for appearance characteristics, body conceptualisation, yoga pose type, risk, and perceived intention. The vast majority of women were perceived to be in their 20s and thin or athletic. Only 13.2 % of women showed average visible levels of body fat, while more than a third displayed visible muscularity across multiple muscle groups. There was little presence of objectification with the majority of women in active poses, though more than 60 % of poses/sequences were advanced and potentially risky. The vast majority of videos appeared to be for the purpose of demonstrating skill rather than instructing the viewer. The findings show that videos on Instagram perpetuate unrealistic appearance ideals in yoga and also provide a platform for content creators to engage viewers by representing yoga as a highly performative, predominantly advanced physical activity.

Is Weekly Frequency of Yoga Practice Sufficient? Physiological Effects of Hatha Yoga Among Healthy Novice Women

Beneficial physical and physiological health outcomes of yoga practice are well-supported by empirical data. However, whether weekly frequency of training is sufficient to evoke positive changes, is still an open question. The present intervention study investigated the effects of 10 weekly sessions of beginner level hatha yoga with respect to indicators of physical fitness and physiological markers. 82 young women (mean age of 22.0 ± 3.83 years) participated in the study. The yoga group (N = 49) attended a yoga course consisting of 10 sessions (1.5 h each) on a weekly basis. The control group (N = 33) did not receive any intervention. BMI, body fat percentage, balance (one-leg-stand test with open and closed eyes, functional reach test), flexibility (side bend test, modified sit and reach test) core muscle strength (plank test) as well as resting heart rate (HR), and heart rate variability (HRV) were assessed 1 week before and after the course. Both frequentist and Bayesian analysis showed an improvement in flexibility and balance in the yoga group compared to the control group. The yoga group showed also increased core muscle strength. No changes with respect to BMI, body fat percentage, resting HR and HRV were found. Ninety minute beginner level hatha yoga classes were characterized by 93.39 HR and 195 kcal energy consumption on average. The present findings suggest that weekly setting of a 10-session long hatha yoga training leads to improvements in balance, flexibility and core muscle strength among healthy young women. However, for changes in BMI, body fat percentage, resting HR and HRV longer, and/or more intense interventions are needed.

The necessity of integrated medicine to treat SARS-Cov-2/COVID-19 patient: A case report

Health policymakers and clinicians should also prioritize mental, emotional and social health while treating SARS-CoV-2/COVID-19, and for this, different treatment varieties of eastern medicine would be a better option to integrate into western medicine so that we could have a better result in all dimensions of health.

The prevalence and characteristics of yoga or meditation users in Iceland: Results of a national health survey

BACKGROUND

Use of yoga or meditation has increased decisively in recent years. Factors associated with the use of yoga and meditation are not well understood. The aim was to focus on the relationship of yoga and meditation to sociodemographic background, religiosity, healthcare-related attitudes, mental and physical health, and physician visits.

MATERIALS AND METHODS

This study builds on data from a national health survey of a random sample of Icelandic adults, aged 18-75 (n = 1599; response rate of 58%).

RESULTS

The overall use of yoga or meditation reached 19.3% in 2015. This is an increase of 12.5% points over a nine-year period. The increase was much greater for women. Yoga or meditation use was positively related to the female gender, younger age, higher levels of education, and not belonging to a religious denomination. It was also positively related to higher anxiety, previous visits to a physician, and a positive attitude toward CAM services, but it was negatively related to having chronic medical conditions.

CONCLUSION

Increased use of yoga or meditation may reflect public interest in Icelander's self-care and health promotion. Further studies are needed to better understand the predictors and effects of yoga and meditation.

Diversification of Physical Activities: An Exploration of Provision Characteristics of Holistic Movement Practices in a Large Australian City

Holistic movement practices (HMPs) are an emerging category of physical activity, contributing to the diversification of physical activity opportunities. Purposefully incorporating not only physical but also mental, social, and/or spiritual elements, HMPs have received limited research attention with respect to participation parameters. The purpose of this study was to begin to map HMPs' participation potential by exploring the provision features of HMPs in Melbourne. Data were collected via internet searches, with a focus on events offered. Event features, including type, cost, duration, venue address, and target groups, were recorded. Associated neighbourhood characteristics were also explored by linking venue locations to selected census information. Provision was documented for Yoga and Pilates in central Melbourne (1011 events), for Tai Chi and Qigong (323 events), and for a range of smaller HMPs (149 events) across Greater Melbourne. Results indicated a wide range in provision features. Affinities with the holistic nature of HMPs were noticeable in venue choices and neighbourhood socio-demographics. Mention of specific target groups was infrequent. Results are discussed in light of implications for uptake. HMPs exemplify the increasing diversity of physical activity opportunities in modern-day societies. Further research to elucidate their place in the landscape of physical activities is warranted.

A Population-Practice-Based Model to Understand How Yoga Impacts on Human Global Functioning: A Qualitative Study

Introduction:Research is increasingly demonstrating a range of benefits of practicing yoga, such as improved physical and mental health, social connectedness, and self-care. Mechanisms of action are less well understood, but may include both psychological and physiological changes. The aim of this study was to understand more about benefits and mechanisms of yoga practice, using qualitative data collected from a large-scale survey of yoga use in the United Kingdom. Methods: The mixed methods, cross-sectional online survey collected data on yoga use and perceived benefits from 2434 U.K. yoga practitioners. The qualitative survey element used open-ended questions to gain "real life" data regarding practice and perceived benefits. Data were analyzed thematically and deductively. A practice-based model describing yoga practice, mechanisms, and benefits, based on the Khalsa logic model of yoga, was developed to explain the data. Findings: Findings highlighted that a diverse range of yoga practices and nonspecific contextual factors related to practicing yoga, needed to be considered to understand how yoga was benefitting people. These practices encompassed both modern and traditional conceptions of yoga as a deeper lifestyle practice. Key mechanisms for change included improvements in physical strength and flexibility, stress regulation, resilience, equanimity, mind-body awareness, and spiritual/personal growth. These mechanisms resulted in diverse improvements in global health functioning, particularly physical and mental health and well-being. Conclusions: The Khalsa model provided a useful base upon which to guide the new population-practice-based model, to understand participants' "real life" experiences of yoga, how yoga is helping people and why. It provides important information for practitioners, teachers, and those delivering yoga interventions as to the range of skills and potential benefits of yoga practice. In addition, findings indicate directions for future research, by highlighting key yoga mechanisms that researchers may choose to focus on in future studies.

The Relationship Between Yoga and Spirituality: A Systematic Review of Empirical Research

OBJECTIVE

Both yoga practice and spirituality are associated with beneficial mental health outcomes. Within yoga research, however, spirituality is still a widely neglected area. The present systematic review aims to explore empirical studies, which do, in fact, investigate the relationship between yoga and spirituality in order to provide an overview and future directions for research on this topic. The review examines whether available empirical research supports an association between yoga practice and spirituality and, if so, which specific aspects of spirituality are associated with yoga practice.

METHODS

The systematic review followed the PRISMA guideline (Prospero registration number: CRD42020155043). Empirical studies written in English, German, or Hungarian language were selected from a database search in Google Scholar, PsycINFO, and Science Direct. A total of 30 studies met the final inclusion criteria.

RESULTS

According to the quantitative and qualitative studies reviewed, yoga practice seems to be positively associated with spirituality. This association concerns various aspects of spirituality, such as spiritual aspirations, a search for insight/wisdom, an integrative worldview, a sense of meaning and peace, faith, hope, compassion, and happiness within. To harness the potential spiritual benefits of yoga, regular practice appears to be essential. Yoga practitioners seem to have both physical and spiritual motives for practicing. At least in Western societies, however, physical intentions are more prevalent than spiritual ones. The meaning of spirituality for yoga practitioners is also discussed. Due to risk of bias of the majority of the reviewed studies, however, outcomes must be taken with caution.

CONCLUSION

Yoga practice may be positively associated with several aspects of spirituality. For more evidence, further investigation of the topic is suggested. Particularly, we propose the inclusion of holistic forms of yoga practice and a comparison of Eastern and Western approaches to yoga.

Effects of a 12-week yoga versus a 12-week educational film intervention on symptoms of restless legs syndrome and related outcomes: an exploratory randomized controlled trial

STUDY OBJECTIVES

To assess the effects of a yoga versus educational film (EF) program on restless legs syndrome (RLS) symptoms and related outcomes in adults with RLS.

METHODS

Forty-one community-dwelling, ambulatory nonpregnant adults with moderate to severe RLS were randomized to a 12-week yoga (n = 19) or EF program (n = 22). In addition to attending classes, all participants completed practice/treatment logs. Yoga group participants were asked to practice at home 30 minutes per day on nonclass days; EF participants were instructed to record any RLS treatments used on their daily logs. Core outcomes assessed pretreatment and posttreatment were RLS symptoms and symptom severity (International RLS Study Group Scale (IRLS) and RLS ordinal scale), sleep quality, mood, perceived stress, and quality of life (QOL).

RESULTS

Thirty adults (13 yoga, 17 EF), aged 24 to 73 (mean = 50.4 ± 2.4 years), completed the 12-week study (78% female, 80.5% white). Post-intervention, both groups showed significant improvement in RLS symptoms and severity, perceived stress, mood, and QOL-mental health (P ≤ .04). Relative to the EF group, yoga participants demonstrated significantly greater reductions in RLS symptoms and symptom severity (P ≤ .01), and greater improvements in perceived stress and mood (P ≤ .04), as well as sleep quality (P = .09); RLS symptoms decreased to minimal/mild in 77% of yoga group participants, with none scoring in the severe range by week 12, versus 24% and 12%, respectively, in EF participants. In the yoga group, IRLS and RLS severity scores declined with increasing minutes of homework practice (r = .7, P = .009 and r = .6, P = .03, respectively), suggesting a possible dose-response relationship.

CONCLUSIONS

Findings of this exploratory RCT suggest that yoga may be effective in reducing RLS symptoms and symptom severity, decreasing perceived stress, and improving mood and sleep in adults with RLS.

Association of yogic breathing with perceived stress and conception of strengths and difficulties in teenagers

BACKGROUND

Mental health problems are increasing at an alarming rate throughout the world, and teenagers are no exception. They experience high levels of stress in their formative years which often leads to poor social behavior. In the present study, we examine the effect of Sudarshan Kriya Yoga (SKY), a yogic breathing technique on perceived stress and social behavior of school going teenagers.

METHOD

A cross-sectional survey was conducted. Teenagers who practiced SKY daily constituted the study group and teenagers who did not practice any form of yoga or meditation formed the control group. Child Perceived Stress scale (C-PSS) and Strength and Difficulty questionnaire (SDQ) were used to evaluate the mental health and social behavior of both groups.

RESULTS

Lower stress scores were observed among students who practiced SKY compared to their peers. A significant difference was observed between the groups with respect to emotional problems, conduct problems, peer problems, and pro-social behavior. Gender wise comparison highlighted that the females from the SKY group scored lower on emotional problems sub-scale compared to their counterparts from control group. Results also highlighted an improved peer to peer interaction among both boys and girls in the SKY group.

CONCLUSION

The results indicate the practice of SKY is associated with reduced stress, improved self-awareness, and social behavior.

The integration of yoga in physical therapy clinical practice

Health professionals are beginning to use yoga as a treatment modality. However, evidence explaining physical therapists' integration of yoga in clinical practice is lacking.

OBJECTIVE

The purpose of this study was to explore how, why, and with whom physical therapists integrate yoga into clinical practice.

DESIGN

This study is a secondary analysis of qualitative data collected during a larger multi-methods study. Thematic analysis of 13 interviews was conducted.

RESULTS

Analysis indicated four themes, and six subthemes. Facilitating yoga in clinical practice and yoga training themes; including evaluation of outcomes, billing, terminology, and safety subthemes describe how physical therapists are using yoga in clinical practice. The perceived client outcomes theme, including physical and psychosocial outcomes explain why physical therapists use yoga in practice. The yoga with clinical populations theme addresses with whom physical therapists are using yoga.

CONCLUSION

Physical therapists are using yoga with individuals with various health conditions to improve their physical and mental health. Findings support the need for physical therapists to increase their assessment and documentation of functional outcomes associated with client's yoga participation. Documentation could contribute to evidence-based literature related to how, why, and with whom physical therapists are using yoga. Documented outcomes could also provide rationale for yoga to receive classification as a reimbursable complementary and integrative health approach. Future research involving a larger, diverse sample (e.g., physical therapists with varying levels of education and yoga training) focused on how, why, and with whom physical therapists integrate yoga into clinical practice is recommended.

Association between yoga, physiologic and psychologic health: A cross sectional study

PURPOSE

To compare markers of health associated with chronic diseases between yoga and non-yoga participants.

METHODS

30 participants were categorized as either: 1) "Yoga" engaging in yoga ≥2 times/week for ≥6 months, or 2) "Non-yoga" not engaging in yoga.

RESULTS

Perceived Stress Scale (PSS) and Beck Depression Inventory-II (BDI-II) scores were significantly different between the yoga and non-yoga groups (PSS: 8.0 vs. 17.5, respectively, p < 0.05; BDI-II: 1.0 vs. 5.5, respectively, p < 0.05). No significant differences were evident between groups for inflammatory markers nor Complex V of the mitochondrial electron transport chain. The erythrocyte sedimentation rate values differed between groups based on clinical cutoffs, with yoga participants categorized as normal (11.0 mm) and non-yoga above normal (21.5 mm).

CONCLUSION

This research supports that yoga participation is associated with lower PSS and BDI-II scores but does not support a relationship with markers of inflammation. Further research is warranted.

A systematic review of yoga interventions for helping health professionals and students

Helping Health Professionals (HHP) and HHP students are among the highest risk occupational groups for compromised mental and physical health. There is a paucity of information regarding preventive interventions for mental and physical health in this group of healthcare providers.

OBJECTIVE

The objective of this review was to examine the effectiveness of yoga interventions for the prevention and reduction of mental and physical disorders among HHPs and HHP students.

DESIGN

An exhaustive systematic search was conducted in May 2020. Databases searched in the OVID interface included: MEDLINE(R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations and Daily, Embase, and PsycINFO. EbscoHost databases searched included: CINAHL Plus with Full Text, SPORTDiscus with Full Text, Alt HealthWatch, Education Research Complete, SocINDEX with Full Text, ERIC, and Academic Search Complete. Scopus was also searched.

RESULTS

The search yielded 4,973 records, and after removal of duplicates 3197 records remained. Using inclusion and exclusion criteria, titles and abstracts were screened and full text articles (n = 82) were retrieved and screened. Twenty-five studies were identified for inclusion in this review. Most frequently reported findings of yoga interventions in this population included a reduction in stress, anxiety, depression, and musculoskeletal pain.

CONCLUSION

It is our conclusion that mental and physical benefits can be obtained through implementation of yoga interventions for HHPs and HHP students across a variety of settings and backgrounds. However, researchers would benefit from following recommended guidelines for the design and reporting of yoga interventions to improve study quality and rigour.

Telemedicine for Musculoskeletal Rehabilitation and Orthopedic Postoperative Rehabilitation

Telehealth visits result in high-quality care, with high patient and provider satisfaction. Strong evidence suggests that virtual physical therapy is noninferior to conventional face-to-face physical therapy for a variety of musculoskeletal disorders. Postoperative telerehabilitation has a strong positive effect on clinical outcomes, and the increased intensity telerehabilitation programs offer is a promising option for patients. Studies demonstrate effective virtual postoperative management. The novel coronavirus disease 2019 pandemic has led to improved reimbursement for telehealth visits and accelerated widespread implementation of telemedicine. This article establishes experience and evidence-based practice guidelines for conducting telemedicine visits, with emphasis on the virtual physical examination.

Effect of Exercise Intensity on Cell-Mediated Immunity

Moderate-intensity exercise is considered to enhance immune function and to be useful for preventing acute upper respiratory infections and similar conditions. Many people practice low-intensity short-duration exercise with the expectation of a beneficial effect on immunocompetency. However, it is difficult to affirm the existence of definite evidence of such a benefit. In this article, we discuss the effects of low-intensity short-duration exercise on cell-mediated immunity, and contrast them to the effects of high-intensity and long-duration exercise. Whereas high-intensity exercise induces inflammation and reduces cell-mediated immune system function, low-intensity exercise does not appear to have a large effect on either inflammation or cell-mediated immune function. Low-intensity exercises such as walking and yoga, which are helpful to relieve stress, cannot be considered as harmful to the immune system. Although yoga was shown to impose fewer restrictions on breathing and physical strain, the evidence that yoga enhances cell-mediated immunity remains insufficient. Therefore, further studies are needed to examine the exercise mode that may be most effective for improvement of immune functions.

Effects of body-oriented yoga: a RCT study for patients with major depressive disorder

The major depressive disorder is one of the most common mental illnesses worldwide. Current treatment standards recommend a combined therapy with medication and psychotherapy. As an additive component and to further improvements in treatment, physical activity such as yoga may be integrated into conventional treatment. This study investigates the impact of a 3-month body-oriented yoga in patients with major depressive disorder (MDD). In total, n = 83 patients were included. An intervention group received a vigorous Ashtanga-Yoga three times a week. The waiting-list control group obtained a treatment as usual (TAU). As a primary outcome depression scores (Beck Depression Inventory-II (BDI-II), Montgomery Asberg Depression Rating Scale (MADRS)) were tested at three time points. Secondary outcome was the positive and negative affect [Positive and Negative Affect Scale (PANAS)] and remission rates. To analyze the data, multilevel models and effect sizes were conducted. The results showed an improvement in BDI-II scores for both groups over time [γ =  -  3.46, t(165) =  - 7.99, p < 0.001] but not between groups [γ = 0.98, t(164) = 1.12, p = 0.263]. An interaction effect (time x group) occurred for MADRS [γ = 2.10, t(164) = 2.10, p < 0.038]. Positive affects improved over time for both groups [γ = 1.65, t(165) = 4.03, p < 0.001]. Negative affects decreased for all over time [γ =  -  1.00, t(165) = - 2.51, p = 0.013]. There were no significant group differences in PANAS. Post hoc tests revealed a greater symptom reduction within the first 6 weeks for all measurements. The effect sizes for depression scores showed a positive trend. Remission rates indicated a significant improvement in the yoga group (BDI-II: 46.81%, MADRS: 17.02%) compared to the control group (BDI: 33.33%, MADRS: 8.33%). The findings suggest that there is a trendsetting additive effect of Ashtanga-Yoga after 3 months on psychopathology and mood with a greater improvement at the beginning of the intervention. Further research in this field can help to achieve more differentiated results.

Effectiveness of Interventions Based on Yogic Breathing Practices (IB-YBP) on Substance Use Disorders-A Systematic Review of the Randomized Control Trials and Quasi-Experimental Trials

Interventions based on Yogic Breathing Practices (IB-YBP) have shown promising results for substance use disorders (SUD). Research in this area is methodologically heterogeneous and only a few, but restricted, systematic reviews are available. The current systematic review aims to assess the effectiveness of IB-YBP for SUD. Materials and Methods: PubMed, Cochrane's Library, EBSCO-Medline, and Google Scholar databases were searched for the randomized- (RCTs) and quasi-randomized trials. Research involving participants with SUD, of either gender or any age, assessing the effectiveness of the IB-YBP either as a standalone intervention or as an adjuvant to standard treatment versus standard pharmacological/non-pharmacological treatment or no-intervention control were included. Studies having participants with co-morbid psychiatric illness and interventions not having IB-YBP as the predominant component were excluded. Results: The initial literature search yielded 396 articles and upon screening, only 14 studies were found eligible for this review. Most studies have researched IB-YBP as an adjunct to the standard treatment for SUD. Evidence for the effectiveness of IB-YBP is mostly available for tobacco and opioid use disorders, though only for short-term outcomes; however, literature is scarce for alcohol- and cocaine-use disorders. This review documented the effectiveness of the IB-YBP for substance use-related outcome parameters such as abstinence, quality of life (QoL), mood, craving, and withdrawal symptoms. Conclusion: IB-YBP may be an effective adjuvant to standard treatment for various SUD. However, more research is required to compare its effectiveness with standard treatment, and assessing its long-term efficacy, for it to be strongly recommended as a treatment strategy.

Mind-Body Physical Activity Interventions and Stress-Related Physiological Markers in Educational Settings: A Systematic Review and Meta-Analysis

Mind–Body Physical Activity (MBPA) in educational settings is one possible preventive strategy for ameliorating stress-related physiological health parameters. The objectives of this study were to conduct a systematic review of the literature with meta-analyses on the effects of MBPA on stress-related physiological health markers in primary, secondary, and higher education students. In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, the search for peer-reviewed articles published in English was conducted in PubMed, EBSCOhost, PsychInfo, Scopus, and Cochrane Library databases. Criteria for inclusion consisted of empirical studies targeting the student population (primary, secondary, higher education), studies examining the effectiveness of an MBPA intervention, studies including a control or comparison group (pre-test/post-test studies excluded), studies targeting physiological marker outcomes such as heart rate, blood glucose, cortisol, and blood pressure, and finally, studies examining interventions implemented within educational settings. Twenty-six interventions were eligible for the review and quantitative synthesis, which comprised a total of 1625 participants, with 783 students serving within the control/comparison group. There were statistically significant and large pooled effects for MBPA effectiveness for lowering heart rate (Hedges’ g = −1.71, 95% Confidence Interval (CI): −2.43, −0.98), cortisol (Hedges’ g = −1.32, 95% CI: −2.50, −0.16), and systolic and diastolic blood pressure (Hedges’ g = −1.04, 95% CI: −1.53, −0.58). These effects tended to be stronger in older students compared to younger students. Most analyses were characterized as having high heterogeneity and only 10 of the 26 studies were characterized as good quality (38.4%). MBPA interventions may have a positive impact on specific physiological health markers in students, especially in students within higher education. However, higher-quality research is needed in this area.
