Therefore, we hypothesized that the experience of yoga may result in adaptation to acute hemodynamic changes. To decipher the long-term effects of yoga on cardiovascular variability, yoga practitioners were compared to yoga-naïve subjects during exposure to -40 mm Hg lower-body negative pressure (LBNP). A comparative study was conducted on 40 yoganaïve subjects and 40 yoga practitioners with an average age of 31.08 ± 7.31 years and 29.93 ± 7.57 years, respectively. Heart rate variability, blood pressure variability, baroreflex sensitivity, and correlation between systolic blood pressure and RR interval were evaluated at rest and during LBNP. In yoga practitioners, the heart rate was lower in supine rest (p = 0.011) and during LBNP (p = 0.043); the pNN50 measure of heart rate variability was higher in supine rest (p = 0.011) and during LBNP (p = 0.034). The yoga practitioners' standard deviation of successive beat-to-beat blood pressure intervals of systolic blood pressure variability was lower in supine rest (p = 0.034) and during LBNP (p = 0.007), with higher sequence baroreflex sensitivity (p = 0.019) and ~ high-frequency baroreflex sensitivity. Mean systolic blood pressure and RR interval were inversely correlated in the yoga group (r = -0.317, p = 0.049). The yoga practitioners exhibited higher parasympathetic activity and baroreflex sensitivity with lower systolic blood pressure variability, indicating better adaptability to LBNP compared to the yoga-naïve group. Our findings indicate that the yoga module was helpful in conditions of hypovolemia in healthy subjects; it is proposed to be beneficial in clinical conditions associated with sympathetic dominance, impaired barore-flex sensitivity, and orthostatic intolerance.</p>","PeriodicalId":38682,"journal":{"name":"International journal of yoga therapy","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39198805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, training sessions typically involve fielding-specific drills and conditioning exercises. Scientific evidence for inclusion of a comprehensive yoga intervention in daily training and exercise sessions remains unexplored. The present study explored the effect of yoga on bowling performance and physical fitness in cricket bowlers. Sports fitness testing and training were conducted among 60 non-elite recreational-club male cricket players aged 13-25 years. Cricket-bowling speed was e valuated using a speed radar gun, accuracy with a test developed by Portus et al., cardiorespiratory endurance using the yo-yo intermittent recovery test, lower-extremity and trunk strength using a back-leg dynamometer, upper-limb power using a medicine ball-throw test, power using a vertical-jump test, and flexibility using a sit-and-reach test. In addition to bowling practice, the yoga intervention group (n = 30) performed pranayama and standing and prone asana, whereas the control group (n = 30) practiced conventional conditioning exercises, for 45 minutes/day, three times a week, for 12 weeks. Improvement in bowling speed, accuracy, cardiorespiratory endurance, muscle strength, and flexibility were comparable between the two groups. Statistically significant improvements in baseline scores in bowling speed, accuracy, cardiorespiratory endurance, muscle flexibility, strength, and power were comparable between the two groups of non-elite male cricket players. Bowling speed improved by 6.52% in the yoga group and by 5.18% in the control group. Bowling accuracy improved by 35.40% in the yoga group and by 31.29% in the control group. Additional research on long-duration intervention in elite players may help to establish the role of yoga in conventional cricket-bowling training.</p>","PeriodicalId":38682,"journal":{"name":"International journal of yoga therapy","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39438942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Publications on yoga between 1948 and 1970 (1.25%) focused on exceptional abilities of experienced yoga practitioners, apparently related to the spiritual goal of yoga; from 1971 to 2000 (6.87%), the focus was on yoga in health and therapy; and from 2001 to 2020 (91.88%), research publications on yoga increased and continued to focus on health and therapy, with fewer RCTs relative to the SRs and MAs on yoga in PubMed. Publications on yoga reported the following health conditions most often: from 1981 to 1990, (1) asthma, (2) stress, and (3) diabetes; from 1991 to 2000, (1) stress followed by (2) asthma, anxiety, and pain (all three with equal percentages); from 2001 to 2010, (1) depression, (2) stress, and (3) anxiety; and from 2011 to 2020, (1) stress, (2) depression, and (3) pain. The journals publishing research on yoga in PubMed have changed between 1971 and 2020 as follows: highly clinically relevant, broad-interest medical journals (1971 to 1990); journals relevant to mind-body interventions (1991 to 2000); and specialized journals for complementary and alternative medicine, particular branches of medicine, or research study designs (2001 to 2020).

Therapies are often geared to improve inspiratory muscle performance. Yoga has been shown to improve exercise capacity, quality of life, and some pulmonary function measures in COPD, but little research has examined the effects of yoga training on inspiratory muscle performance. The purpose of this study was to investigate the effects of yoga training on inspiratory muscle performance in military veterans using the Test of Incremental Respiratory Endurance (TIRE). A prospective pilot study examined a 6-week yoga training program consisting of asana (poses) and pranayama (controlled breathing). Subjects had baseline inspiratory muscle weakness. The TIRE measured inspiratory muscle performance via the PrO2 device, providing maximal inspiratory pressure, sustained maximal inspiratory pressure, and inspiratory duration. Secondary measures included 6-minute walk distance, St. George Respiratory Questionnaire, Hospital Anxiety and Depression Scale, and spirometry. Mean age and BMI of subjects were 67 ± 3.6 years and 20.7 ± 3.3, respectively. The majority of subjects had severe (28.7%) or very severe (57.1%) COPD. Statistically significant improve m e n t s were seen in maximal inspiratory pressure (39.0 ± 14.1 cmH2O to 56.4 ± 20.6 cmH2O) and sustained maximal inspiratory pressure (244.1 ± 100.6 PTU to 308.1 ± 121.2 PTU). No statistically significant improvements we re observed in 6-minute walk distance, St. George Respiratory Questionnaire, Hospital Anxiety and Depression Scale, or spirometry.

The current study, the first of its kind, addresses existing gaps in the literature by examining the social and emotional effects of mindfulness on instructors of color, a largely understudied population. All trainees (n = 25) in a year-long, mindfulness-based workforce development program in Baltimore were invited to participate in this qualitative descriptive study that involved semistructured interviews regarding the personal emotional impact of participating in the program, as well as possible changes in the subjects' perceptions of yoga and the potential role of yoga in their communities. We applied a transcript-based analysis approach to the data from the individual interviews and derived themes using the constant comparative method. Twenty-one trainees (84%) participated in semistructured interviews. Participants were between the ages of 18 and 29 and were predominantly male (71.4%) and African-American (85.7%). We identified four key themes related to participating in the program: (1) changes in emotional functioning and self-perception, (2) changes in interactions with others, (3) changes in perception of yoga and mindfulness, and (4) perceived real-world application of yoga and mindfulness. The current study adds to the literature by exploring the public health implications of mindfulness, particularly in addressing effects of chronic trauma in low-income communities of color. The workforce development program also merits further evaluation as a potential model for enabling local and national nonprofit organizations to offer low-income youth and youth of color employment options that enhance resources in trauma-affected communities.</p>","PeriodicalId":38682,"journal":{"name":"International journal of yoga therapy","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38818417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purposes of this study were to: (1) assess the readiness of PTs (those who do not currently prescribe TY to patients) to integrate TY into treatment, and (2) determine the feasibility of a 5-week online TY training to improve the readiness of PTs to utilize TY in their practices. Licensed PTs (n = 103) were recruited nationally through social media and email. Eligible and consented PTs registered for a 5-week online TY training course. PTs' perceptions of TY and the role of safety and confidence in prescribing TY to patients were measured at baseline and postintervention. Feasibility outcomes were measured after completion of the course. Benchmarks included: (1) > 70% of PTs would find the course acceptable; (2) > 60% would finish the course; and (3) there would be significant improvements in PTs' perceptions of TY. A total of 95 eligible PTs consented and registered for the course, with 60 (63.1%) completing the intervention.
