1 1811 133 PROFILE OF MOOD STATES AND STRESS-RELATED BIOCHEMICAL INDICES IN LONG-TERM YOGA PRACTITIONERS. BACKGROUND: PREVIOUS STUDIES HAVE SHOWN THE SHORT-TERM OR INTERMEDIATE-TERM PRACTICE OF YOGA TO BE USEFUL FOR AMELIORATING SEVERAL MENTAL DISORDERS AND PSYCHOSOMATIC DISORDERS. HOWEVER, LITTLE IS KNOWN ABOUT THE LONG-TERM INFLUENCES OF YOGA ON THE MENTAL STATE OR STRESS-RELATED BIOCHEMICAL INDICES. IF YOGA TRAINING HAS A STRESS-REDUCTION EFFECT AND ALSO IMPROVES AN INDIVIDUAL'S MENTAL STATES FOR A LONG TIME, LONG-TERM YOGA PRACTITIONERS MAY HAVE A BETTER MENTAL STATE AND LOWER STRESS-RELATED BIOCHEMICAL INDICES IN COMPARISON TO NON-EXPERIENCED PARTICIPANTS. THIS STUDY SIMULTANEOUSLY EXAMINED THE DIFFERENCES IN MENTAL STATES AND URINARY STRESS-RELATED BIOCHEMICAL INDICES BETWEEN LONG-TERM YOGA PRACTITIONERS AND NON-EXPERIENCED PARTICIPANTS. METHODS: THE PARTICIPANTS WERE 38 HEALTHY FEMALES WITH MORE THAN 2 YEARS OF EXPERIENCE WITH YOGA (LONG-TERM YOGA GROUP) AND 37 AGE-MATCHED HEALTHY FEMALES WHO HAD NOT PARTICIPATED IN YOGA (CONTROL GROUP). THEIR MENTAL STATES WERE ASSESSED USING THE PROFILE OF MOOD STATES (POMS) QUESTIONNAIRE. THE LEVEL OF CORTISOL, 8-HYDROXYDEOXYGUANOSINE (8-OHDG) AND BIOPYRRIN IN URINE WERE USED AS STRESS-RELATED BIOCHEMICAL INDICES. RESULTS: THE AVERAGE SELF-RATED MENTAL DISTURBANCE, TENSION-ANXIETY, ANGER-HOSTILITY, AND FATIGUE SCORES OF THE LONG-TERM YOGA GROUP WERE LOWER THAN THOSE OF THE CONTROL GROUP. THERE WAS A TREND TOWARD A HIGHER VIGOR SCORE IN THE LONG-TERM YOGA GROUP THAN THAT IN THE CONTROL GROUP. THERE WERE NO SIGNIFICANT DIFFERENCES IN THE SCORES FOR DEPRESSION AND CONFUSION IN THE POMS BETWEEN THE TWO GROUPS. THE URINE 8-OHDG CONCENTRATION SHOWED A TREND TOWARD TO BEING LOWER IN THE LONG-TERM YOGA GROUP IN COMPARISON TO THE CONTROL GROUP. THERE WERE NO SIGNIFICANT DIFFERENCES IN THE LEVELS OF URINE BIOPYRRIN OR CORTISOL. CONCLUSIONS: THE PRESENT FINDINGS SUGGEST THAT LONG-TERM YOGA TRAINING CAN REDUCE THE SCORES RELATED TO MENTAL HEALTH INDICATORS SUCH AS SELF-RATED ANXIETY, ANGER, AND FATIGUE.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
2 2001  40 STRESS, INFLAMMATION, AND YOGA PRACTICE. OBJECTIVE: TO ADDRESS THE MECHANISMS UNDERLYING HATHA YOGA'S POTENTIAL STRESS-REDUCTION BENEFITS, WE COMPARED INFLAMMATORY AND ENDOCRINE RESPONSES OF NOVICE AND EXPERT YOGA PRACTITIONERS BEFORE, DURING, AND AFTER A RESTORATIVE HATHA YOGA SESSION, AS WELL AS IN TWO CONTROL CONDITIONS. STRESSORS BEFORE EACH OF THE THREE CONDITIONS PROVIDED DATA ON THE EXTENT TO WHICH YOGA SPEEDED AN INDIVIDUAL'S PHYSIOLOGICAL RECOVERY. METHODS: A TOTAL OF 50 HEALTHY WOMEN (MEAN AGE, 41.32 YEARS; RANGE, 30-65 YEARS), 25 NOVICES AND 25 EXPERTS, WERE EXPOSED TO EACH OF THE CONDITIONS (YOGA, MOVEMENT CONTROL, AND PASSIVE-VIDEO CONTROL) DURING THREE SEPARATE VISITS. RESULTS: THE YOGA SESSION BOOSTED PARTICIPANTS' POSITIVE AFFECT COMPARED WITH THE CONTROL CONDITIONS, BUT NO OVERALL DIFFERENCES IN INFLAMMATORY OR ENDOCRINE RESPONSES WERE UNIQUE TO THE YOGA SESSION. IMPORTANTLY, EVEN THOUGH NOVICES AND EXPERTS DID NOT DIFFER ON KEY DIMENSIONS, INCLUDING AGE, ABDOMINAL ADIPOSITY, AND CARDIORESPIRATORY FITNESS, NOVICES' SERUM INTERLEUKIN (IL)-6 LEVELS WERE 41% HIGHER THAN THOSE OF EXPERTS ACROSS SESSIONS, AND THE ODDS OF A NOVICE HAVING DETECTABLE C-REACTIVE PROTEIN (CRP) WERE 4.75 TIMES AS HIGH AS THAT OF AN EXPERT. DIFFERENCES IN STRESS RESPONSES BETWEEN EXPERTS AND NOVICES PROVIDED ONE PLAUSIBLE MECHANISM FOR THEIR DIVERGENT SERUM IL-6 DATA; EXPERTS PRODUCED LESS LIPOPOLYSACCHARIDE-STIMULATED IL-6 IN RESPONSE TO THE STRESSOR THAN NOVICES, AND IL-6 PROMOTES CRP PRODUCTION. CONCLUSION: THE ABILITY TO MINIMIZE INFLAMMATORY RESPONSES TO STRESSFUL ENCOUNTERS INFLUENCES THE BURDEN THAT STRESSORS PLACE ON AN INDIVIDUAL. IF YOGA DAMPENS OR LIMITS STRESS-RELATED CHANGES, THEN REGULAR PRACTICE COULD HAVE SUBSTANTIAL HEALTH BENEFITS.	2010	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
3 2760  44 YOGA PRACTITIONERS UNIQUELY ACTIVATE THE SUPERIOR PARIETAL LOBULE AND SUPRAMARGINAL GYRUS DURING EMOTION REGULATION. CHRONIC STRESS CONTRIBUTES TO BOTH MENTAL AND PHYSICAL ILLNESS. A HIGH PREVALENCE AND COST OF STRESS-RELATED ILLNESSES NORTH AMERICA WARRANTS INVESTIGATION INTO ALTERNATIVE OR COMPLEMENTARY THERAPIES WHICH MAY HELP REDUCE ADVERSE REACTIONS TO STRESSFUL STIMULI. EMOTION REGULATION IS THE PROCESS OF MONITORING AND ADJUSTING EMOTIONAL RESPONSES TO ENVIRONMENTAL STIMULI AND STRESSORS. INDIVIDUALS WHO PARTICIPATE IN PHYSICAL ACTIVITY ARE LESS LIKELY TO HAVE ADVERSE RESPONSES TO POTENTIALLY STRESSFUL SITUATIONS, POTENTIALLY DUE TO ADAPTIONS IN EMOTION REGULATION. YOGA IS A FORM OF PHYSICAL ACTIVITY INVOLVING STRETCHING EXERCISES AND MEDITATION, THAT MAY LESSEN INDIVIDUALS' LEVELS OF STRESS AND ANXIETY AND IMPROVE EMOTION REGULATION. HIGH-FREQUENCY HEART RATE VARIABILITY (HF-HRV) IS CONSIDERED A MEASURE OF PARASYMPATHETIC NERVOUS SYSTEM (PNS) ACTIVITY DURING THE EMOTION REGULATION. MEASURING HRV AND BRAIN ACTIVITY USING FUNCTIONAL MAGNETIC RESONANCE IMAGING (FMRI) OFFERS A USEFUL, NONINVASIVE APPROACH TO EVALUATING "NEUROVISCERAL" COMPONENTS OF EMOTION REGULATION. WE AIMED TO DETERMINE WHETHER YOGA PRACTITIONERS (YP) EXHIBIT DIFFERENT PATTERNS OF BRAIN ACTIVATION COMPARED TO RECREATIONAL ATHLETES (RA) WITHOUT CURRENT YOGA EXPERIENCE, WHILE VIEWING EMOTIONALLY AROUSING VISUAL STIMULI. OUR SECONDARY AIM WAS TO EXAMINE POTENTIAL DIFFERENCES ACROSS GROUPS IN HRV THROUGHOUT THE PRESENTATION OF THESE STIMULI. ANALYSIS OF FMRI DATA DURING EXPOSURE TO EMOTION-EVOKING (EE) STIMULI REVEALED THAT THE YP GROUP ACTIVATED TWO UNIQUE BRAIN AREAS, NAMELY THE SUPERIOR PARIETAL LOBULE AND THE SUPRAMARGINAL GYRUS. THESE AREAS HAVE BEEN ASSOCIATED WITH ATTENTIONAL AWARENESS AND REDUCED EGOCENTRIC BIAS, PROCESSES THAT HAVE BEEN IMPLICATED IN EMOTION REGULATION BY OTHERS. THE RA GROUP ACTIVATED THE INFERIOR MIDDLE FRONTAL CORTEX, AN AREA ASSOCIATED WITH COGNITIVE REAPPRAISAL DURING EMOTION REGULATION. THE YP GROUP ALSO DEMONSTRATED A TREND TOWARDS A HIGHER RATIO OF LOW- TO HIGH-FREQUENCY HRV COMPARED TO THE RA GROUP. THE PRESENT FINDINGS SUPPORT THE PRESENCE OF EXPERIENCE-DEPENDENT NEUROVISCERAL MECHANISMS ASSOCIATED WITH EMOTION REGULATION. INDIVIDUALS WHO PRACTICE YOGA REGULATE THEIR NEUROVISCERAL RESPONSES TO POTENTIALLY STRESSFUL EXTERNAL STIMULI IN A DIFFERENT MANNER THAN RECREATIONAL ATHLETES WHO DO NOT ENGAGE IN YOGA PRACTICE. THE PRESENT STUDY HAD A SMALL SAMPLE SIZE (RA: N = 12; YP: N = 19), WHICH SHOULD BE TAKEN INTO ACCOUNT WHEN INTERPRETING THE RESULTS.	2018	

4 1319  36 HEART RATE VARIABILITY, FLOW, MOOD AND MENTAL STRESS DURING YOGA PRACTICES IN YOGA PRACTITIONERS, NON-YOGA PRACTITIONERS AND PEOPLE WITH METABOLIC SYNDROME. HEART RATE VARIABILITY (HRV) AND RESPIRATORY SINUS ARRHYTHMIA ARE DIRECTLY ASSOCIATED WITH AUTONOMIC FLEXIBILITY, SELF-REGULATION AND WELL-BEING, AND INVERSELY ASSOCIATED WITH PHYSIOLOGICAL STRESS, PSYCHOLOGICAL STRESS AND PATHOLOGY. YOGA ENHANCES AUTONOMIC ACTIVITY, MITIGATES STRESS AND BENEFITS STRESS-RELATED CLINICAL CONDITIONS, YET THE RELATIONSHIP BETWEEN AUTONOMIC ACTIVITY AND PSYCHOPHYSIOLOGICAL RESPONSES DURING YOGA PRACTICES AND STRESSFUL STIMULI HAS NOT BEEN WIDELY EXPLORED. THIS EXPERIMENTAL STUDY EXPLORED THE RELATIONSHIP BETWEEN HRV, MOOD STATES AND FLOW EXPERIENCES IN REGULAR YOGA PRACTITIONERS (YP), NON-YOGA PRACTITIONERS (NY) AND PEOPLE WITH METABOLIC SYNDROME (METS), DURING MENTAL ARITHMETIC STRESS TEST (MAST) AND VARIOUS YOGA PRACTICES. THE STUDY FOUND THAT THE MAST PLACED A CARDIO-AUTONOMIC BURDEN IN ALL PARTICIPANTS WITH THE YP GROUP SHOWING THE GREATEST REACTIVITY AND THE MOST RAPID RECOVERY, WHILE THE METS GROUP HAD SIGNIFICANTLY BLUNTED RECOVERY. THE YP GROUP ALSO REPORTED A HEIGHTENED EXPERIENCE OF FLOW AND POSITIVE MOOD STATES COMPARED TO NY AND METS GROUPS AS WELL AS HAVING A HIGHER VAGAL TONE DURING ALL RESTING CONDITIONS. THESE RESULTS SUGGEST YOGA PRACTITIONERS HAVE A GREATER HOMEOSTATIC CAPACITY AND AUTONOMIC, METABOLIC AND PHYSIOLOGICAL RESILIENCE. FURTHER STUDIES ARE NOW NEEDED TO DETERMINE IF REGULAR YOGA PRACTICE MAY IMPROVE AUTONOMIC FLEXIBILITY IN NON-YOGA PRACTITIONERS AND METABOLIC SYNDROME PATIENTS.

5 2014  33 SUDARSHAN KRIYA YOGA: BREATHING FOR HEALTH. BREATHING TECHNIQUES ARE REGULARLY RECOMMENDED FOR RELAXATION, STRESS MANAGEMENT, CONTROL OF PSYCHOPHYSIOLOGICAL STATES, AND TO IMPROVE ORGAN FUNCTION. YOGIC BREATHING, DEFINED AS A MANIPULATION OF BREATH MOVEMENT, HAS BEEN SHOWN TO POSITIVELY AFFECT IMMUNE FUNCTION, AUTONOMIC NERVOUS SYSTEM IMBALANCES, AND PSYCHOLOGICAL OR STRESS-RELATED DISORDERS. THE AIM OF THIS STUDY WAS TO ASSESS AND PROVIDE A COMPREHENSIVE REVIEW OF THE PHYSIOLOGICAL MECHANISMS, THE MIND-BODY CONNECTION, AND THE BENEFITS OF SUDARSHAN KRIYA YOGA (SKY) IN A WIDE RANGE OF CLINICAL CONDITIONS. VARIOUS ONLINE DATABASES SEARCHED WERE MEDLINE, PSYCHINFO, EMBASE, AND GOOGLE SCHOLAR. ALL THE RESULTS WERE CAREFULLY SCREENED AND ARTICLES ON SKY WERE SELECTED. THE REFERENCES FROM THESE ARTICLES WERE CHECKED TO FIND ANY OTHER POTENTIALLY RELEVANT ARTICLES. SKY, A UNIQUE YOGIC BREATHING PRACTICE, INVOLVES SEVERAL TYPES OF CYCLICAL BREATHING PATTERNS, RANGING FROM SLOW AND CALMING TO RAPID AND STIMULATING. THERE IS MOUNTING EVIDENCE TO SUGGEST THAT SKY CAN BE A BENEFICIAL, LOW-RISK, LOW-COST ADJUNCT TO THE TREATMENT OF STRESS, ANXIETY, POST-TRAUMATIC STRESS DISORDER, DEPRESSION, STRESS-RELATED MEDICAL ILLNESSES, SUBSTANCE ABUSE, AND REHABILITATION OF CRIMINAL OFFENDERS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
6 1640  35 MOLECULAR SIGNATURE OF THE IMMUNE RESPONSE TO YOGA THERAPY IN STRESS-RELATED CHRONIC DISEASE CONDITIONS: AN INSIGHT. THE WORLD HEALTH ORGANIZATION DEFINES HEALTH AS COMPLETE WELL-BEING IN TERMS OF PHYSICAL, MENTAL AND SOCIAL, AND NOT MERELY THE ABSENCE OF DISEASE. TO ATTAIN THIS, INDIVIDUAL SHOULD ADAPT AND SELF-MANGE THE SOCIAL, PHYSICAL AND EMOTIONAL CHALLENGES OF LIFE. EXPOSURE TO CHRONIC STRESS DUE TO URBANIZATION, WORK STRESS, NUCLEAR FAMILY, POLLUTION, UNHEALTHY FOOD HABITS, LIFESTYLE, ACCIDENTAL DEATH IN THE FAMILY, AND NATURAL CALAMITIES ARE THE TRIGGERING FACTORS, LEADING TO HORMONAL IMBALANCE AND INFLAMMATION IN THE TISSUE. THE RELATIONSHIP BETWEEN STRESS AND ILLNESS IS COMPLEX; ALL CHRONIC ILLNESSES SUCH AS CARDIOVASCULAR DISEASE AND ASTHMA HAVE THEIR ROOT IN CHRONIC STRESS ATTRIBUTED BY INFLAMMATION. IN RECENT TIMES, YOGA THERAPY HAS EMERGED AS AN IMPORTANT COMPLEMENTARY ALTERNATIVE MEDICINE FOR MANY HUMAN DISEASES. YOGA THERAPY HAS A POSITIVE IMPACT ON MIND AND BODY; IT ACTS BY INCORPORATING APPROPRIATE BREATHING TECHNIQUES AND MINDFULNESS TO ATTAIN CONSCIOUS DIRECTION OF OUR AWARENESS OF THE PRESENT MOMENT BY MEDITATION, WHICH HELPS ACHIEVE HARMONY BETWEEN THE BODY AND MIND. STUDIES HAVE ALSO DEMONSTRATED THE IMPORTANT REGULATORY EFFECTS OF YOGA THERAPY ON BRAIN STRUCTURE AND FUNCTIONS. DESPITE THESE ADVANCES, THE CELLULAR AND MOLECULAR MECHANISMS BY WHICH YOGA THERAPY RENDERS ITS BENEFICIAL EFFECTS ARE INADEQUATELY KNOWN. A GROWING BODY OF EVIDENCE SUGGESTS THAT YOGA THERAPY HAS IMMUNOMODULATORY EFFECTS. HOWEVER, THE PRECISE MECHANISTIC BASIS HAS NOT BEEN ADDRESSED EMPIRICALLY. IN THIS REVIEW, WE HAVE ATTEMPTED TO HIGHLIGHT THE EFFECT OF YOGA THERAPY ON IMMUNE SYSTEM FUNCTIONING WITH AN AIM TO IDENTIFY IMPORTANT IMMUNOLOGICAL SIGNATURES THAT INDEX THE EFFECT OF YOGA THERAPY. TOWARD THIS, WE HAVE SUMMARIZED THE AVAILABLE SCIENTIFIC EVIDENCE SHOWING POSITIVE IMPACTS OF YOGA THERAPY. FINALLY, WE HAVE EMPHASIZED THE EFFICACY OF YOGA IN IMPROVING PHYSICAL AND MENTAL WELL-BEING. YOGA HAS BEEN A PART OF INDIAN CULTURE AND TRADITION FOR LONG; NOW, THE TIME HAS COME TO SCIENTIFICALLY VALIDATE THIS AND IMPLEMENT THIS AS AN ALTERNATIVE TREATMENT METHOD FOR STRESS-RELATED CHRONIC DISEASE.	2020	
                                                                                                                                                                                                                                                                                                                                                                               
7  661  80 EFFECT OF 12 WEEKS OF YOGA TRAINING ON THE SOMATIZATION, PSYCHOLOGICAL SYMPTOMS, AND STRESS-RELATED BIOMARKERS OF HEALTHY WOMEN. BACKGROUND: PREVIOUS STUDIES HAVE SHOWN THAT THE PRACTICE OF YOGA REDUCES PERCEIVED STRESS AND NEGATIVE FEELINGS AND THAT IT IMPROVES PSYCHOLOGICAL SYMPTOMS. OUR PREVIOUS STUDY ALSO SUGGESTED THAT LONG-TERM YOGA TRAINING IMPROVES STRESS-RELATED PSYCHOLOGICAL SYMPTOMS SUCH AS ANXIETY AND ANGER. HOWEVER, LITTLE IS KNOWN ABOUT THE BENEFICIAL EFFECTS OF YOGA PRACTICE ON SOMATIZATION, THE MOST COMMON STRESS-RELATED PHYSICAL SYMPTOMS, AND STRESS-RELATED BIOMARKERS. WE PERFORMED A PROSPECTIVE, SINGLE ARM STUDY TO EXAMINE THE BENEFICIAL EFFECTS OF 12 WEEKS OF YOGA TRAINING ON SOMATIZATION, PSYCHOLOGICAL SYMPTOMS, AND STRESS-RELATED BIOMARKERS. METHODS: WE RECRUITED HEALTHY WOMEN WHO HAD NO EXPERIENCE WITH YOGA. THE DATA OF 24 PARTICIPANTS WHO WERE FOLLOWED DURING 12 WEEKS OF YOGA TRAINING WERE ANALYZED. SOMATIZATION AND PSYCHOLOGICAL SYMPTOMS WERE ASSESSED BEFORE AND AFTER 12 WEEKS OF YOGA TRAINING USING THE PROFILE OF MOOD STATE (POMS) AND THE SYMPTOM CHECKLIST-90-REVISED (SCL-90-R) QUESTIONNAIRES. URINARY 8-HYDROXYDEOXYGUANOSINE (8-OHDG), BIOPYRRIN, AND CORTISOL LEVELS WERE MEASURED AS STRESS-RELATED BIOMARKERS. THE WILCOXON SIGNED-RANK TEST WAS USED TO COMPARE THE STRESS-RELATED BIOMARKERS AND THE SCORES OF QUESTIONNAIRES BEFORE AND AFTER 12 WEEKS OF YOGA TRAINING. RESULTS: AFTER 12 WEEKS OF YOGA TRAINING, ALL NEGATIVE SUBSCALE SCORES (TENSION-ANXIETY, DEPRESSION, ANGER-HOSTILITY, FATIGUE, AND CONFUSION) FROM THE POMS AND SOMATIZATION, ANXIETY, DEPRESSION, AND HOSTILITY FROM THE SCL-90-R WERE SIGNIFICANTLY DECREASED COMPARED WITH THOSE BEFORE STARTING YOGA TRAINING. CONTRARY TO OUR EXPECTATION, THE URINARY 8-OHDG CONCENTRATION AFTER 12 WEEKS OF YOGA TRAINING SHOWED A SIGNIFICANT INCREASE COMPARED WITH THAT BEFORE STARTING YOGA TRAINING. NO SIGNIFICANT CHANGES WERE OBSERVED IN THE LEVELS OF URINARY BIOPYRRIN AND CORTISOL AFTER THE 12 WEEKS OF YOGA TRAINING. CONCLUSIONS: YOGA TRAINING HAS THE POTENTIAL TO REDUCE THE SOMATIZATION SCORE AND THE SCORES RELATED TO MENTAL HEALTH INDICATORS, SUCH AS ANXIETY, DEPRESSION, ANGER, AND FATIGUE. THE PRESENT FINDINGS SUGGEST THAT YOGA CAN IMPROVE SOMATIZATION AND MENTAL HEALTH STATUS AND HAS IMPLICATIONS FOR THE PREVENTION OF PSYCHOSOMATIC SYMPTOMS IN HEALTHY WOMEN.

8 1211  32 EXPLORING HOW DIFFERENT TYPES OF YOGA CHANGE PSYCHOLOGICAL RESOURCES AND EMOTIONAL WELL-BEING ACROSS A SINGLE SESSION. OBJECTIVES: YOGA DEMONSTRATES BENEFICIAL EFFECTS IN MANY POPULATIONS, YET OUR UNDERSTANDING OF HOW YOGA BRINGS ABOUT THESE EFFECTS IS QUITE LIMITED. AMONG THE PROPOSED MECHANISMS OF YOGA ARE INCREASING PSYCHOLOGICAL RESOURCES (MINDFULNESS, BODY CONSCIOUSNESS, SELF-TRANSCENDENCE, SPIRITUAL PEACE, AND SOCIAL CONNECTEDNESS) THAT MAY BRING ABOUT SALUTARY EFFECTS ON EMOTIONAL WELLBEING. FURTHER, YOGA IS A COMPLEX PRACTICE COMPRISING MEDITATION, ACTIVE AND RESTORATIVE POSTURES, AND BREATHWORK; HOWEVER LITTLE IS KNOWN ABOUT HOW DIFFERENT COMPONENTS MAY AFFECT MECHANISMS. WE AIMED TO DETERMINE HOW AN ACUTE SESSION OF YOGA (AND ITS SPECIFIC COMPONENTS) RELATED TO PRE- TO POST- SESSION CHANGES IN PROPOSED MECHANISMS (PSYCHOLOGICAL RESOURCES) AND WHETHER THOSE CHANGES WERE ASSOCIATED WITH POSITIVE CHANGES IN EMOTIONS. DESIGN: 144 REGULAR YOGA PRACTITIONERS COMPLETED MEASURES OF MINDFULNESS, BODY CONSCIOUSNESS, SELF-TRANSCENDENCE, SOCIAL CONNECTEDNESS, SPIRITUAL PEACE, AND EXERCISE-INDUCED EMOTIONS (POSITIVE ENGAGEMENT, REVITALIZATION, TRANQUILITY, EXHAUSTION) IMMEDIATELY BEFORE AND AFTER A YOGA SESSION (N=11 SESSIONS, EACH A DIFFERENT TYPE OF YOGA). PERCEIVED PROPERTIES OF EACH YOGA SESSION, EXERCISE EXERTION AND ENGAGEMENT WITH THE YOGA TEACHER WERE ASSESSED IMMEDIATELY FOLLOWING THE SESSION. RESULTS: PRE-TO POST- YOGA, LEVELS OF POSITIVE EMOTIONS (ENGAGEMENT, TRANQUILITY AND REVITALIZATION) INCREASED WHILE EXHAUSTION DECREASED. FURTHER, ALL PSYCHOLOGICAL RESOURCES INCREASED AND CLOSELY TRACKED IMPROVED EMOTIONS. ADDITIONALLY, ASPECTS OF THE YOGA SESSION CORRELATED WITH CHANGES IN PSYCHOLOGICAL RESOURCES (MECHANISMS) AND EMOTIONS. CONCLUSIONS: YOGA MAY INFLUENCE MULTIPLE PSYCHOLOGICAL MECHANISMS THAT INFLUENCE EMOTIONAL WELL-BEING. FURTHER, DIFFERENT TYPES OF YOGA MAY AFFECT DIFFERENT MECHANISMS. RESULTS CAN INFORM YOGA INTERVENTIONS AIMING TO OPTIMIZE EFFECTS THROUGH SPECIFIC MECHANISMS SUCH AS MINDFULNESS OR SPIRITUALITY.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
9 1882  26 REDUCING ALLOSTATIC LOAD IN DEPRESSION AND ANXIETY DISORDERS: PHYSICAL ACTIVITY AND YOGA PRACTICE AS ADD-ON THERAPIES. THE ALLOSTATIC LOAD (AL) INDEX CONSTITUTES A USEFUL TOOL TO OBJECTIVELY ASSESS THE BIOLOGICAL ASPECTS OF CHRONIC STRESS IN CLINICAL PRACTICE. AL INDEX HAS BEEN POSITIVELY CORRELATED WITH CUMULATIVE CHRONIC STRESS (PHYSICAL AND PSYCHOSOCIAL STRESSORS) AND WITH A HIGH RISK TO DEVELOP PATHOLOGICAL CONDITIONS (E.G., METABOLIC SYNDROME, CARDIOVASCULAR PATHOLOGY, INFLAMMATORY DISORDERS) AND THE SO-CALLED STRESS-RELATED PSYCHIATRIC DISORDERS, INCLUDING ANXIETY AND DEPRESSIVE DISORDERS. CHRONIC STRESS HAS NEGATIVE EFFECTS ON BRAIN NEUROPLASTICITY, ESPECIALLY ON HIPPOCAMPAL NEUROGENESIS AND THESE EFFECTS MAY BE REVERSED BY ANTIDEPRESSANT TREATMENTS. SEVERAL EVIDENCES INDICATE THAT NON-PHARMACOLOGICAL INTERVENTIONS BASED ON PHYSICAL ACTIVITY AND YOGA PRACTICE MAY ADD SYNERGIZING BENEFITS TO CLASSICAL TREATMENTS (ANTIDEPRESSANT AND BENZODIAZEPINES) FOR DEPRESSION AND ANXIETY, REDUCING THE NEGATIVE EFFECTS OF CHRONIC STRESS. THE AIM OF THIS REVIEW IS TO PROVIDE A GENERAL OVERVIEW OF CURRENT KNOWLEDGE ON AL AND CHRONIC STRESS IN RELATION TO DEPRESSION AND ANXIETY, PHYSICAL ACTIVITY AND YOGA PRACTICE.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
10 1879  35 REASONS, YEARS AND FREQUENCY OF YOGA PRACTICE: EFFECT ON EMOTION RESPONSE REACTIVITY. YOGA PRACTICE, EVEN IN THE SHORT TERM, IS SUPPOSED TO ENHANCE WELLBEING AND COUNTERACT PSYCHOPATHOLOGY THROUGH MODIFICATION OF EMOTION REACTIVITY. YOGA TEACHES THAT EMOTIONAL RESPONSES MAY BE LESS PRONOUNCED WITH LONGER AND MORE FREQUENT PRACTICE, AND POTENTIALLY WHEN PEOPLE PERFORM YOGA FOR MENTAL RATHER THAN PHYSICAL REASONS. WE TESTED 36 YOGA PRACTITIONERS OF VARYING EXPERIENCE (BETWEEN 6 MONTHS AND 11 YEARS OF PRACTICE). WE ASSESSED PARTICIPANTS' SELF-REPORTED EMOTIONAL EXPERIENCE AND PERIPHERAL PHYSIOLOGICAL REACTIONS (HEART RATE, SKIN CONDUCTANCE, RESPIRATION) WHEN SEEING POSITIVE AND NEGATIVE PICTURES. RESULTS WERE ANALYZED AS A FUNCTION OF THE YEARS OF, FREQUENCY OF, AND REASONS FOR YOGA PRACTICE. WE FOUND A HEART RATE INCREASE WITH THE DEGREE PARTICIPANTS PERFORMED YOGA FOR MENTAL REASONS. IN ADDITION, YEARS OF YOGA PRACTICE WERE SIGNIFICANTLY ASSOCIATED WITH REDUCED ABDOMINAL RESPIRATORY RATE WHEN FACING NEGATIVE PICTURES, SPEAKING IN FAVOR OF REDUCED AROUSAL WITH YOGA EXPERIENCE. FINALLY, REGARDING FREQUENCY OF PRACTICE, A HIGHER FREQUENCY IN THE LAST MONTH WAS LINKED TO LESS NEGATIVE AND POSITIVE EXPERIENCES AS WELL AS A REDUCED ABDOMINAL RESPIRATORY AMPLITUDE WHEN VIEWING POSITIVE PICTURES. ALTOGETHER, THESE RESULTS DEMONSTRATE THAT INTENSE SHORT-TERM YOGA PRACTICE MIGHT RELATE TO A (I) DECREASE IN THE INTENSITY OF SELF-REPORTED EMOTIONAL EXPERIENCES AND (II) DEEPENED RESPIRATION. SHORT-TERM EFFECTS MIGHT BE SHAPED BY WHAT PARTICIPANTS EXPECT AS PRACTICE BENEFITS. HOWEVER, SEVERAL YEARS OF PRACTICE MIGHT BE NEEDED TO DECREASE RESPIRATORY AROUSAL IN THE FACE OF NEGATIVE SITUATIONS, WHICH LIKELY IS A MANIFESTATION OF AN EVOLUTION IN THE EMOTION REGULATION PROCESS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
11 1336  29 HOW DOES YOGA REDUCE STRESS? A CLINICAL TRIAL TESTING PSYCHOLOGICAL MECHANISMS. YOGA INTERVENTIONS CAN REDUCE STRESS, BUT THE MECHANISMS UNDERLYING THAT STRESS REDUCTION REMAIN LARGELY UNIDENTIFIED. UNDERSTANDING HOW YOGA WORKS IS ESSENTIAL TO OPTIMIZING INTERVENTIONS. THE PRESENT STUDY TESTED FIVE POTENTIAL PSYCHOSOCIAL MECHANISMS (INCREASED MINDFULNESS, INTEROCEPTIVE AWARENESS, SPIRITUAL WELL-BEING, SELF-COMPASSION AND SELF-CONTROL) THAT HAVE BEEN PROPOSED TO EXPLAIN YOGA'S IMPACT ON STRESS. FORTY-TWO PARTICIPANTS (62% FEMALE; 64% WHITE) IN A YOGA PROGRAM FOR STRESS REDUCTION COMPLETED SURVEYS AT BASELINE (T1), MID-INTERVENTION (T2) AND POST-INTERVENTION (12 WEEKS; T3). WE MEASURED TWO ASPECTS OF STRESS, PERCEIVED STRESS AND STRESS REACTIVITY. CHANGES WERE ASSESSED WITH PAIRED T-TESTS; ASSOCIATIONS BETWEEN CHANGES IN MECHANISMS WERE TESTED IN RESIDUAL CHANGE MODELS. ONLY STRESS REACTIVITY DECREASED, ON AVERAGE, FROM T1 TO T3. EXCEPT FOR SELF-COMPASSION, ALL PSYCHOSOCIAL MECHANISMS INCREASED FROM T1 TO T3, WITH MINIMAL CHANGES FROM T2 TO T3. EXCEPT FOR SELF-CONTROL, INCREASES IN EACH MECHANISM WERE STRONGLY ASSOCIATED WITH DECREASES IN BOTH MEASURES OF STRESS BETWEEN T1 AND T2 AND DECREASES IN PERCEIVED STRESS FROM T1 TO T3 (ALL P'S < 0.05). INCREASED PSYCHOSOCIAL RESOURCES ARE ASSOCIATED WITH STRESS REDUCTION. YOGA INTERVENTIONS TARGETING THESE RESOURCES MAY SHOW STRONGER STRESS REDUCTION EFFECTS. FUTURE RESEARCH SHOULD TEST THESE LINKAGES MORE RIGOROUSLY USING ACTIVE COMPARISON GROUPS AND LARGER SAMPLES.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
12  588  30 DETERMINING PSYCHONEUROIMMUNOLOGIC MARKERS OF YOGA AS AN INTERVENTION FOR PERSONS DIAGNOSED WITH PTSD: A SYSTEMATIC REVIEW. THERE IS A GROWING BODY OF RESEARCH ON YOGA AS A THERAPEUTIC INTERVENTION FOR PSYCHOLOGICAL SYMPTOMS OF POST-TRAUMATIC STRESS DISORDER (PTSD) ACCOMPANIED BY SPECULATIONS ON UNDERLYING PHYSIOLOGIC MECHANISMS. THE PURPOSE OF THIS SYSTEMATIC REVIEW IS TO IDENTIFY, QUALITATIVELY EVALUATE, AND SYNTHESIZE STUDIES OF YOGA AS AN INTERVENTION FOR PTSD THAT MEASURED PHYSIOLOGIC OUTCOMES IN ORDER TO GAIN INSIGHTS INTO POTENTIAL MECHANISMS. THE FOCUS IS ON STUDIES EVALUATING YOGA AS A THERAPEUTIC INTERVENTION FOR PTSD RATHER THAN FOR TRAUMA EXPOSURE, PTSD PREVENTION, OR SUBCLINICAL PTSD. MULTIPLE DATABASES WERE SEARCHED FOR PUBLICATIONS FROM THE PAST TWO DECADES USING TERMS DERIVED FROM THE QUESTION, "IN PEOPLE WITH PTSD, WHAT IS THE EFFECT OF YOGA ON OBJECTIVE OUTCOMES?" ELIGIBILITY CRITERIA INCLUDED YOGA-ONLY MODALITIES TESTED AS AN INTERVENTION FOR FORMALLY DIAGNOSED PTSD WITH AT LEAST ONE PHYSIOLOGIC OUTCOME. RESULTS OF THIS REVIEW CONFIRMED THAT, THOUGH MUCH OF THE PUBLISHED LITERATURE PROPOSES PHYSIOLOGICAL MECHANISMS UNDERLYING YOGA'S EFFECTS ON PTSD, VERY FEW STUDIES ( N = 3) HAVE ACTUALLY EVALUATED PHYSIOLOGICAL EVIDENCE. ADDITIONALLY, SEVERAL STUDIES HAD METHODOLOGICAL LIMITATIONS. IN LIGHT OF THE LIMITED DATA SUPPORTING YOGA'S BENEFICIAL EFFECTS ON AUTONOMIC NERVOUS SYSTEM DYSREGULATION, WE PRESENT A THEORETICAL MODEL OF THE PSYCHONEUROIMMUNOLOGIC PROCESSES ASSOCIATED WITH PTSD AND THE EFFECTS YOGA MAY HAVE ON THESE PROCESSES TO GUIDE FUTURE RESEARCH. GAPS IN THE LITERATURE REMAIN FOR MECHANISMS RELATED TO ACTIVATION OF THE HYPOTHALAMIC-PITUITARY-ADRENAL AXIS AND INFLAMMATION. ADDITIONAL RIGOROUS MECHANISTIC STUDIES ARE NEEDED TO GUIDE DEVELOPMENT OF EFFECTIVE YOGA INTERVENTIONS FOR PTSD TO AUGMENT EXISTING EVIDENCE-BASED PTSD TREATMENTS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
13 2013  30 SUDARSHAN KRIYA YOGA: A BREATH OF HOPE DURING COVID-19 PANDEMIC. IMPORTANT COUNTER MEASURES TO COMBAT AN INFECTIOUS DISEASE PANDEMIC INCLUDE VACCINATION, ANTIVIRAL THERAPY, AND IMMUNOMODULATION THERAPY. VACCINATIONS ARE DISEASE SPECIFIC AND MOREOVER STRAIN SPECIFIC, SO THE PROTECTION PROVIDED IS ALSO SPECIFIC AND LIMITED. ANTIVIRAL THERAPIES ARE COSTLY AND REQUIRE BULK PRODUCTION OF DRUGS, HENCE GLOBALLY THERE IS AN INCREASED INTEREST TOWARD LOW-RISK, COST-EFFECTIVE COMPLEMENTARY ALTERNATIVE THERAPIES, SUCH AS YOGA AND AYURVEDA TO TACKLE THE INFECTIOUS PANDEMIC, CORONAVIRUS DISEASE 2019 (COVID-19). THERE IS CLINICAL EVIDENCE AVAILABLE ON THE POTENTIAL COMPLEMENTARY ROLE OF YOGIC PRACTICES IN THE MANAGEMENT OF NONCOMMUNICABLE AND COMMUNICABLE DISEASES. VARIOUS ONLINE DATABASES WERE SEARCHED FOR ARTICLES PUBLISHED BETWEEN 2000 AND 2020. DATABASES EXPLORED WERE MEDLINE, EMBASE, INDIAN CITATION INDEX, PSYCINFO, INDEX MEDICUS FOR SOUTH-EAST ASIA REGION, AND GOOGLE SCHOLAR. ALL SEARCH RESULTS WERE SCREENED, AND ARTICLES RELATED TO KEYWORDS SUCH AS COVID-19, YOGA THERAPY, AND SUDARSHAN KRIYA YOGA (SKY) WERE SELECTED FOR DATA EXTRACTION. QUALITY OF THE STUDIES INCLUDED WAS EVALUATED ON THE BASIS OF THE CONSTRUCT VALIDITY, CONTENT VALIDITY, RELEVANCE, BIAS, CREDIBILITY RELATING TO INFORMATION, AND DATA SOURCES. SKY IS A UNIQUE YOGIC PRACTICE THAT INCLUDES SPECIFIC SEQUENTIAL BREATHING TECHNIQUES. IT BALANCES THE AUTONOMIC NERVOUS SYSTEM AND THUS CAN ALLEVIATE ANXIETY, ROUTINE STRESS, DEPRESSION, STRESS-RELATED MEDICAL DISORDERS, AND POSTTRAUMATIC STRESS. IT POTENTIATES NATURAL HOST IMMUNE DEFENSES THAT ARE ESSENTIAL TO TACKLE A PLETHORA OF MICROBIAL INFECTIONS. THIS NARRATIVE REVIEW ARTICLE PROVIDES AN OVERVIEW OF POTENTIAL THERAPEUTIC BENEFITS THAT SKY CAN OFFER TO THE POPULATION AT LARGE DURING THIS COVID-19 PANDEMIC.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
14 1575  32 MANAGING MENTAL HEALTH DISORDERS RESULTING FROM TRAUMA THROUGH YOGA: A REVIEW. THERE ARE MANY AND VARIED TYPES OF TRAUMA. THE EXTENT TO WHICH TRAUMA INFLUENCES THE MENTAL HEALTH OF AN INDIVIDUAL DEPENDS ON THE NATURE OF TRAUMA, AS WELL AS ON THE INDIVIDUAL'S COPING CAPABILITIES. OFTEN TRAUMA IS FOLLOWED BY DEPRESSION, ANXIETY, AND PTSD. AS THE PHARMACOLOGICAL REMEDIES FOR THESE CONDITIONS OFTEN HAVE UNDESIRABLE SIDE-EFFECTS, NONPHARMACOLOGICAL REMEDIES ARE THOUGHT OF AS A POSSIBLE ADD-ON TREATMENT. YOGA IS ONE SUCH MIND-BODY INTERVENTION. THIS PAPER COVERS ELEVEN STUDIES INDEXED IN PUBMED, IN WHICH MENTAL HEALTH DISORDERS RESULTING FROM TRAUMA WERE MANAGED THROUGH YOGA INCLUDING MEDITATION. THE AIM WAS TO EVALUATE THE USE OF YOGA IN MANAGING TRAUMA-RELATED DEPRESSION, ANXIETY, PTSD AND PHYSIOLOGICAL STRESS FOLLOWING EXPOSURE TO NATURAL CALAMITIES, WAR, INTERPERSONAL VIOLENCE, AND INCARCERATION IN A CORRECTIONAL FACILITY. AN ATTEMPT HAS ALSO BEEN MADE TO EXPLORE POSSIBLE MECHANISMS UNDERLYING BENEFITS SEEN. AS MOST OF THESE STUDIES WERE NOT DONE ON PERSONS EXPOSED TO TRAUMA THAT HAD PRACTICED YOGA, THIS IS A DEFINITE AREA FOR FURTHER RESEARCH.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
15 1604  29 MENTAL HEALTH PROMOTION FOR YOUNG PEOPLE - THE CASE FOR YOGA IN SCHOOLS. BACKGROUND: MENTAL WELLBEING AMONG YOUNG PEOPLE IS DETERIORATING. POOR MENTAL WELLBEING CAN BE RELATED TO UNMANAGED STRESS. ADVERSE CHILDHOOD EXPERIENCES ARE WIDESPREAD AND RESULT IN YOUNG PEOPLE HAVING STRESSFUL LIVES. STRESS HAS MANY MANIFESTATIONS, AND COPING WITH IT CAN LEAD TO RISKY HEALTH-RELATED BEHAVIOURS. MAIN BODY: A SAFE, SCIENTIFICALLY-SUPPORTED, EFFICIENT AND EFFECTIVE SET OF STRESS-REDUCTION SKILLS IS PROVIDED BY THE PRACTICE OF YOGA. AT PRESENT, YOGA IS AVAILABLE PRIVATELY, NOT PUBLICLY. AFTER APPROPRIATELY DESIGNED AND EVALUATED INTERVENTIONS, THE PUBLIC PROVISION OF YOGA COULD BE INTEGRATED WITHIN THE SCHOOL CURRICULUM, THEREBY REDUCING THE HIGH PREVALENCE OF PRESCRIPTION MEDICATION AND OFFERING A PREVENTATIVE STRATEGY TO PROMOTE POSITIVE MENTAL HEALTH AMONG YOUNG PEOPLE. SHORT CONCLUSION: WE SUGGEST THAT THE LONG-TERM BENEFITS OF AN INVESTMENT IN A CURRICULUM-EMBEDDED SCHOOL-BASED YOGA PROGRAMME WOULD DO MUCH TO REDUCE STRESS BOTH NOW FOR FUTURE GENERATIONS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
16 1337  31 HOW DOES YOGA REDUCE STRESS? A SYSTEMATIC REVIEW OF MECHANISMS OF CHANGE AND GUIDE TO FUTURE INQUIRY. YOGA IS INCREASINGLY USED IN CLINICAL SETTINGS FOR A VARIETY OF MENTAL AND PHYSICAL HEALTH ISSUES, PARTICULARLY STRESS-RELATED ILLNESSES AND CONCERNS, AND HAS DEMONSTRATED PROMISING EFFICACY. YET THE WAYS IN WHICH YOGA REDUCES STRESS REMAIN POORLY UNDERSTOOD. TO EXAMINE THE EMPIRICAL EVIDENCE REGARDING THE MECHANISMS THROUGH WHICH YOGA REDUCES STRESS, WE CONDUCTED A SYSTEMATIC REVIEW OF THE LITERATURE, INCLUDING ANY YOGA INTERVENTION THAT MEASURED STRESS AS A PRIMARY DEPENDENT VARIABLE AND TESTED A MECHANISM OF THE RELATIONSHIP WITH MEDIATION. OUR ELECTRONIC DATABASE SEARCH YIELDED 926 ABSTRACTS, OF WHICH 71 WERE CHOSEN FOR FURTHER INSPECTION AND 5 WERE SELECTED FOR THE FINAL SYSTEMATIC REVIEW. THESE FIVE STUDIES EXAMINED THREE PSYCHOLOGICAL MECHANISMS (POSITIVE AFFECT, MINDFULNESS AND SELF-COMPASSION) AND FOUR BIOLOGICAL MECHANISMS (POSTERIOR HYPOTHALAMUS, INTERLEUKIN-6, C-REACTIVE PROTEIN AND CORTISOL). POSITIVE AFFECT, SELF-COMPASSION, INHIBITION OF THE POSTERIOR HYPOTHALAMUS AND SALIVARY CORTISOL WERE ALL SHOWN TO MEDIATE THE RELATIONSHIP BETWEEN YOGA AND STRESS. IT IS STRIKING THAT THE LITERATURE DESCRIBING POTENTIAL MECHANISMS IS GROWING RAPIDLY, YET ONLY SEVEN MECHANISMS HAVE BEEN EMPIRICALLY EXAMINED; MORE RESEARCH IS NECESSARY. ALSO, FUTURE RESEARCH OUGHT TO INCLUDE MORE RIGOROUS METHODOLOGY, INCLUDING SUFFICIENT POWER, STUDY RANDOMISATION AND APPROPRIATE CONTROL GROUPS.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
17 1193  36 EXAMINING MECHANISMS OF CHANGE IN A YOGA INTERVENTION FOR WOMEN: THE INFLUENCE OF MINDFULNESS, PSYCHOLOGICAL FLEXIBILITY, AND EMOTION REGULATION ON PTSD SYMPTOMS. OBJECTIVE: THIS STUDY EXPLORED POSSIBLE MECHANISMS THROUGH WHICH SYMPTOMS OF POSTTRAUMATIC STRESS DISORDER (PTSD) WERE REDUCED IN A RANDOMIZED CONTROLLED TRIAL COMPARING THE EFFECT OF A YOGA INTERVENTION WITH AN ASSESSMENT CONTROL. METHOD: WE EXAMINED WHETHER CHANGES IN PSYCHOLOGICAL FLEXIBILITY, MINDFULNESS, AND EMOTION REGULATION STRATEGIES (EXPRESSIVE SUPPRESSION AND REAPPRAISAL) WERE ASSOCIATED WITH POSTTREATMENT PTSD SYMPTOMS FOR 38 WOMEN WITH DIAGNOSTIC AND STATISTICAL MANUAL OF MENTAL DISORDERS FOURTH EDITION FULL OR SUBTHRESHOLD PTSD. RESULTS: HIERARCHICAL LINEAR REGRESSION MODELS REVEALED THAT EXPRESSIVE SUPPRESSION SIGNIFICANTLY DECREASED FOR THE YOGA GROUP RELATIVE TO THE ASSESSMENT CONTROL. PSYCHOLOGICAL FLEXIBILITY INCREASED SIGNIFICANTLY FOR THE CONTROL BUT NOT YOGA GROUP. HOWEVER, INCREASES IN PSYCHOLOGICAL FLEXIBILITY WERE ASSOCIATED WITH DECREASES IN PTSD SYMPTOMS FOR THE YOGA BUT NOT CONTROL GROUP. CONCLUSION: PRELIMINARY FINDINGS SUGGEST THAT YOGA MAY REDUCE EXPRESSIVE SUPPRESSION AND MAY IMPROVE PTSD SYMPTOMS BY INCREASING PSYCHOLOGICAL FLEXIBILITY. MORE RESEARCH IS NEEDED TO REPLICATE AND EXTEND THESE FINDINGS.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
18  226  33 A SYSTEMATIC REVIEW OF RANDOMISED CONTROL TRIALS ON THE EFFECTS OF YOGA ON STRESS MEASURES AND MOOD. STRESS RELATED DISORDERS SUCH AS DEPRESSION AND ANXIETY ARE LEADING SOURCES OF DISABILITY WORLDWIDE, AND CURRENT TREATMENT METHODS SUCH AS CONVENTIONAL ANTIDEPRESSANT MEDICATIONS ARE NOT BENEFICIAL FOR ALL INDIVIDUALS. THERE IS EVIDENCE THAT YOGA HAS MOOD-ENHANCING PROPERTIES POSSIBLY RELATED TO ITS INHIBITORY EFFECTS ON PHYSIOLOGICAL STRESS AND INFLAMMATION, WHICH ARE FREQUENTLY ASSOCIATED WITH AFFECTIVE DISORDERS. HOWEVER THE BIOLOGICAL MECHANISMS VIA WHICH YOGA EXERTS ITS THERAPEUTIC MOOD-MODULATING EFFECTS ARE LARGELY UNKNOWN. THIS SYSTEMATIC REVIEW INVESTIGATES THE EFFECTS OF YOGA ON SYMPATHETIC NERVOUS SYSTEM AND HYPOTHALAMIC PITUITARY ADRENAL AXIS REGULATION MEASURES. IT FOCUSES ON STUDIES COLLECTING PHYSIOLOGICAL PARAMETERS SUCH AS BLOOD PRESSURE, HEART RATE, CORTISOL, PERIPHERAL CYTOKINE EXPRESSION AND/OR STRUCTURAL AND FUNCTIONAL BRAIN MEASURES IN REGIONS INVOLVED IN STRESS AND MOOD REGULATION. OVERALL THE 25 RANDOMISED CONTROL STUDIES DISCUSSED PROVIDE PRELIMINARY EVIDENCE TO SUGGEST THAT YOGA PRACTICE LEADS TO BETTER REGULATION OF THE SYMPATHETIC NERVOUS SYSTEM AND HYPOTHALAMIC-PITUITARY-ADRENAL SYSTEM, AS WELL AS A DECREASE IN DEPRESSIVE AND ANXIOUS SYMPTOMS IN A RANGE OF POPULATIONS. FURTHER RESEARCH IS WARRANTED TO CONFIRM THESE PRELIMINARY FINDINGS AND FACILITATE IMPLEMENTATION IN CLINICAL SETTINGS.	2015

THE PURPOSE OF THIS RANDOMIZED CONTROLLED TRIAL IS TO COMPARE ISHA YOGA PRACTITIONERS TO CONTROLS ON PERCEIVED STRESS, RESILIENCE, WELLBEING, AND PROTECTION AND RECOVERY FROM COVID-19. TRIAL DESIGN. IN THIS PROSPECTIVE RANDOMIZED CONTROL TRIAL, THE EFFECTS OF YOGA PRACTICES ARE BEING COMPARED BETWEEN SEASONED YOGA PRACTITIONERS WITH TWO CONTROLS WHO ARE AGE (+/-3 YEARS), GENDER MATCHED, AND LIVING IN THE SAME NEIGHBORHOOD. METHODS: PARTICIPANTS WILL BE ASKED TO COMPLETE A SERIES OF WEB-BASED SURVEYS AT BASELINE, SIX WEEKS, AND 12 WEEKS. THESE SURVEYS INCLUDE VALIDATED SCALES AND OBJECTIVE QUESTIONS ON COVID-19 INFECTION AND MEDICAL HISTORY. THE VALIDATED QUESTIONNAIRES ASSESS STRESS, MOOD STATES, RESILIENCE, AND OVERALL WELLBEING. QUESTIONNAIRES, WEEKLY ACTIVITY DIARIES, AND MEDICAL HISTORY, WILL BE COLLECTED USING REDCAP. RESULTS: WE HYPOTHESIZE THAT ROUTINE YOGA PRACTICE DURING THE COVID-19 PANDEMIC WILL REDUCE STRESS, ENHANCE WELL-BEING, AND PROVIDE PROTECTIVE EFFECTS AGAINST COVID-19. CONCLUSION: WITH THE GROWING CONCERN ABOUT THE PHYSICAL AND MENTAL IMPACTS OF COVID-19 AND INCREASED INTEREST IN ALTERNATIVE PRACTICES SUCH AS YOGIC PRACTICES, THIS STUDY WILL CONTRIBUTE TO THE GROWING BODY OF EVIDENCE ABOUT THE SAFETY AND EFFICACY OF YOGA FOR EMOTIONAL, MENTAL, AND PHYSICAL HEALTH CONDITIONS.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
20 1723  35 PERCEPTIONS OF HATHA YOGA AMONGST PERSISTENTLY DEPRESSED INDIVIDUALS ENROLLED IN A TRIAL OF YOGA FOR DEPRESSION. OBJECTIVES: TO UNDERSTAND DEPRESSED INDIVIDUALS' EXPERIENCES IN A 10-WEEK HATHA YOGA PROGRAM. DESIGN: IN A RANDOMIZED CONTROLLED TRIAL, PARTICIPANTS WERE ASSIGNED TO EITHER 10 WEEKS OF HATHA YOGA CLASSES OR A HEALTH EDUCATION CONTROL GROUP. THIS REPORT INCLUDES RESPONSES FROM PARTICIPANTS IN YOGA CLASSES. AT THE START OF CLASSES, AVERAGE DEPRESSION SYMPTOM SEVERITY LEVEL WAS MODERATE. MAIN OUTCOME MEASURES: AFTER 10 WEEKS OF YOGA CLASSES, WE ASKED PARTICIPANTS (N=50) TO PROVIDE WRITTEN RESPONSES TO OPEN-ENDED QUESTIONS ABOUT WHAT THEY LIKED ABOUT CLASSES, WHAT THEY DID NOT LIKE OR DID NOT FIND HELPFUL, AND WHAT THEY LEARNED. WE ANALYZED QUALITATIVE DATA USING THEMATIC ANALYSIS. RESULTS AND CONCLUSIONS: ELEMENTS OF YOGA CLASSES THAT MAY INCREASE ACCEPTABILITY FOR DEPRESSED INDIVIDUALS INCLUDE HAVING INSTRUCTORS WHO PROMOTE A NON-COMPETITIVE AND NON-JUDGMENTAL ATMOSPHERE, WHO ARE KNOWLEDGEABLE AND ABLE TO PROVIDE INDIVIDUALIZED ATTENTION, AND WHO ARE KIND AND WARM. INCLUDING DEPRESSION-RELATED THEMES IN CLASSES, TEACHING MINDFULNESS, TEACHING BREATHING EXERCISES, AND PROVIDING GUIDANCE FOR TRANSLATING CLASS INTO HOME PRACTICE MAY HELP TO MAKE YOGA EFFECTIVE FOR TARGETING DEPRESSION. PARTICIPANTS' COMMENTS REINFORCED THE IMPORTANCE OF ASPECTS OF MINDFULNESS, SUCH AS ATTENTION TO THE PRESENT MOMENT AND ACCEPTANCE OF ONE'S SELF AND ONE'S EXPERIENCE, AS POTENTIAL MECHANISMS OF ACTION. OTHER POTENTIAL MECHANISMS INCLUDE USE OF BREATHING PRACTICES IN EVERYDAY LIFE AND THE BIOLOGICAL MECHANISMS THAT UNDERLIE THE POSITIVE IMPACT OF YOGIC BREATHING. THE MOST SERIOUS CONCERN HIGHLIGHTED BY A FEW PARTICIPANTS WAS THE CONCERN THAT THE YOGA CLASSES WERE TOO DIFFICULT GIVEN THEIR PHYSICAL ABILITIES.	2017
