1 2272 151 THE ROLE OF YOGA IN INFLAMMATORY MARKERS. YOGA IS AN ANCIENT SYSTEM FOR INTEGRATING THE MIND, BODY, AND SPIRIT. IN THE HATHA YOGA ASHTANGA TRADITION (THE EIGHT LIMB PATANJALI YOGA), THREE OF THE LIMBS ARE MEDITATION, BREATHWORK (PRANAYAMA) AND PHYSICAL POSTURES (ASANA), WHICH ARE WIDELY PRACTISED IN YOGA CLASSES. THE BENEFITS OF YOGA FOR MENTAL AND PHYSICAL HEALTH ARE ROOTED IN THE PRACTICE'S ORIGINS: IN YOGA, STRESS IS SAID TO BE THE ROOT OF ALL DISEASES. THE ESTABLISHED FIELDS OF PSYCHONEUROIMMUNOLOGY AND IMMUNOPSYCHIATRY STUDY THE INTERPLAY BETWEEN THE IMMUNE SYSTEM AND MOOD OR MENTAL STATES. THIS MINI-REVIEW HAS SHIFTED THE EMPHASIS FROM RESEARCH THAT FOCUSES ON YOGA'S BENEFITS FOR STRESS, THE MOST COMMONLY STUDIED OUTCOME OF YOGA RESEARCH, TO A SUMMARY OF THE RESEARCH ON THE EFFECTS OF YOGA PRACTICES ON THE IMMUNE SYSTEM. THE CURRENT LITERATURE BEARS STRONG EVIDENCE FOR THE BENEFITS OF YOGA ON THE LEVELS OF CIRCULATING CORTISOL AND CLASSICAL INFLAMMATORY MARKERS, SUCH AS C-REACTIVE PROTEIN (CRP) AND CYTOKINES SUCH AS INTERLEUKIN-1 BETA (IL-1BETA), INTERLEUKIN 6 (IL-6), TUMOUR NECROSIS FACTOR-ALPHA (TNF-ALPHA) AND INTERFERON-GAMMA (INF-GAMMA). THE EVIDENCE FOR OTHER LESS STUDIED MARKERS, TELOMERASE ACTIVITY, BETA-ENDORPHINS, IMMUNOGLOBULIN A (IGA) AND BRAIN-DERIVED NEUROTROPHIC FACTOR (BDNF) IS ALSO GROWING. THIS MINI-REVIEW CENTRES AROUND THE INTERPLAY BETWEEN YOGA AND THESE MARKERS IN STRESS MANAGEMENT AND DEPRESSION, VASCULAR AND IMMUNE FUNCTION IN THE OLDER POPULATION, CARDIOVASCULAR AND METABOLIC DISEASES, AUTO-IMMUNE DISEASES, BREAST CANCER AND PREGNANCY. OVERALL, THE LITERATURE EXAMINED REVEALS THE NOVELTY OF THIS FIELD OF RESEARCH AND SHEDS LIGHT ON METHODOLOGICAL CHALLENGES; HOWEVER, IT UNCOVERS THE POTENTIAL FOR YOGA TO BE USED AS ADJUVANT THERAPY IN CONDITIONS WITH AN INFLAMMATORY COMPONENT.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
2 2835  37 YOGA'S EFFECTS ON THE CARDIOVASCULAR SYSTEM OF HEALTHY WOMEN: IMPLICATIONS FOR BEST PRACTICES. CONTEXT: YOGA AS A FORM OF PHYSICAL ACTIVITY IS GROWING IN POPULARITY. DURING YOGA, INDIVIDUALS INTERRUPT THE STRESS RESPONSE, WHICH IS TYPICALLY ASSOCIATED WITH HIGH BLOOD PRESSURE (BP), IMPAIRED FOCUS, AND HIGH LEVELS OF ANXIETY. CONSEQUENTLY, RESEARCH INTO YOGA'S EFFECTS ON STRESS SHOULD PLACE A SPECIAL EMPHASIS UPON THE INTERPLAY OF THE NERVOUS AND CARDIOVASCULAR SYSTEMS DURING YOGA PRACTICE. OBJECTIVE: THE PURPOSE OF THIS STUDY WAS TO DELINEATE THE IMMEDIATE CARDIOVASCULAR EFFECTS OF 12 HATHA YOGA POSES BY MEANS OF RR (BEAT-TO-BEAT) INTERVALS AND JT (CARDIAC REPOLARIZATION) INTERVALS. DESIGN: THE RESEARCH TEAM DESIGNED CONTROLLED PILOT STUDIES BASED ON HALF-YEAR PERIODS. SETTING: THE STUDY TOOK PLACE AT THE LITHUANIAN UNIVERSITY OF HEALTH SCIENCES IN KAUNAS, LITHUANIA. PARTICIPANTS: PARTICIPANTS WERE WOMEN WHO WERE LONG-TERM YOGA PRACTITIONERS. THREE STUDIES OCCURRED: (1) STUDY 1-10 WOMEN WITH A MEAN AGE OF 30.1 +/- 1.9 YEARS, (2) STUDY 2-10 WOMEN WITH A MEAN AGE OF 29.9 +/- 1.9 YEARS, AND (3) STUDY 3-22 WOMEN WITH A MEAN AGE OF 32.9 +/- 1.8 YEARS. INTERVENTION: THE STUDY EXAMINED THE ACUTE CARDIOVASCULAR EFFECTS OF 12 HATHA YOGA POSES BY MEANS OF ELECTROCARDIOGRAM PARAMETERS. OUTCOME MEASURES: ANTHROPOMETRICAL AND PHYSIOLOGICAL PARAMETERS WERE MEASURED: (1) HEIGHT AND WEIGHT; (2) BODY MASS INDEX (BMI); (3) HEART RATE (HR); (4) SYSTOLIC AND DIASTOLIC BLOOD PRESSURE (DBP); AND (5) ELECTROCARDIOGRAM (ECG) RR AND JT INTERVALS. RESULTS: THE LOWEST RR INTERVAL VALUE WAS RECORDED DURING THE CHATURANGA DANDASANA, AT 456.0 +/- 16.5 MS IN STUDY 3, WITH P < .001 COMPARED TO THE INTERVALS FOR ALL THE OTHER POSES. SIGNIFICANT DIFFERENCES IN THE JT INTERVAL ALSO EMERGED DURING THE CHATURANGA DANDASANA, AT 177.3 +/- 6.0 MS IN STUDY 3 WITH P < .001 COMPARED TO ALL THE OTHER POSES. THE NEXT LOWEST RR INTERVAL VALUE WAS RECORDED IN STUDY 3 DURING THE UTKATASANA, AT 569.4 +/- 17.6 MS. IN THE SAVASANA PRIOR TO THE PROGRAM, THE RR INTERVAL INCREASED IN STUDY 1 AND DECREASED IN STUDIES 2 AND 3. THE JT INTERVAL IN THE SAVASANA PRIOR TO THE PROGRAM INCREASED IN STUDIES 1 AND 2 BUT DECREASED IN STUDY 3. CONCLUSIONS: HEALTHY WOMEN CAN PRACTICE A MODIFIED AND/OR A SHORTER DURATION OF THE CHATURANGA DANDASANA. ADJUSTMENTS IN THE UTKATASANA, INCLUDING HAVING THE ARMS IN THE PRAYER POSITION, MAY HELP PREVENT STRAIN TO THE CARDIOVASCULAR SYSTEM. ALSO, PRACTICING POSES WITH A LONGER RR INTERVAL MAY AID STRESS-RELATED HEALTH PROBLEMS.	2020	

3 1913  33 ROLE OF BREATHING EXERCISES IN ASTHMA-YOGA AND PRANAYAMA. ASTHMA IS A CHRONIC AIRWAY INFLAMMATORY DISEASE THAT RESULTS FROM A COMPLEX INTERPLAY OF GENETIC, ENVIRONMENTAL, AND LIFESTYLE FACTORS. THERE IS NO CURE FOR ASTHMA, AND THE MANAGEMENT IS USUALLY AS PER PUBLISHED GUIDELINES. AS IN MANY CHRONIC DISEASES CONDITIONS, VARIOUS ALTERNATIVE OR COMPLIMENTARY THERAPIES HAVE BEEN TRIED. OF THESE, YOGA AND PRANAYAMA HAVE GAINED WIDER ATTENTION IN RECENT YEARS. WHILE THE TERM YOGA IS A COMPLEX TERM ENCOMPASSING EIGHT LIMBS AS PER PATAMJAI IN THE YOGA SUTRAS, IN SIMPLE TERMS, YOGA IS DESCRIBED AS A COMBINATION OF 'ASANA' (PHYSICAL EXERCISES) AND 'PRANAYAMA' (BREATHING EXERCISE). THE TERM "ASTHMA" HAS BEEN DERIVED FROM THE GREEK WORD "PANTING,", WHICH INDICATES A RAPID AND SHALLOW BREATHING. THE MAIN AIM OF YOGA AND PRANAYAMA IN ASTHMA IS TO SYNCHRONIZE AND CONTROL BREATHING, THUS DECREASING HYPERVENTILATION. BESIDES THIS, THEY ALSO DECREASE THE STRESS/STRAIN/ANXIETY, CHANGE IN BEHAVIOR, BOOST IMMUNITY, AND IMPROVE STRENGTH/ENDURANCE OF RESPIRATORY MUSCLES THAT ARE HELPFUL IN ANY SUBJECT WITH ASTHMA. THERE HAVE BEEN A GOOD NUMBER OF STUDIES INCLUDING CLINICAL TRIALS IN CHILDREN WITH ASTHMA THAT HAVE FOUND SOME BENEFICIAL EFFECTS. IN THE PRESENT REVIEW, THE PHYSIOLOGY OF YOGA AND PRANAYAMA, RATIONALE FOR THEIR USE IN CHILDREN WITH ASTHMA ALONG WITH A SUMMARY OF VARIOUS STUDIES CONDUCTED TILL DATE, HAVE BEEN DISCUSSED. THESE ARE FOLLOWED BY RECOMMENDATIONS REGARDING THEIR INCORPORATION IN THE STANDARD OF CARE OF CHILDREN WITH ASTHMA.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
4 1675  31 OBESITY-RELATED INFLAMMATION & CARDIOVASCULAR DISEASE: EFFICACY OF A YOGA-BASED LIFESTYLE INTERVENTION. OBESITY IS A GLOBAL HEALTH BURDEN AND ITS PREVALENCE IS INCREASING SUBSTANTIALLY DUE TO CHANGING LIFESTYLE. CHRONIC ADIPOSITY IS ASSOCIATED WITH METABOLIC IMBALANCE LEADING TO DYSLIPIDAEMIA, DIABETES, HYPERTENSION AND CARDIOVASCULAR DISEASES (CVD). ADIPOSE TISSUE ACTS AS AN ENDOCRINE ORGAN RELEASING SEVERAL ADIPOCYTOKINES, AND IS ASSOCIATED WITH INCREASED LEVELS OF TISSUE AND CIRCULATING INFLAMMATORY BIOMOLECULES CAUSING VASCULAR INFLAMMATION AND ATHEROGENESIS. FURTHER, INFLAMMATION IS ALSO ASSOCIATED INDEPENDENTLY WITH OBESITY AS WELL AS CVD. KEEPING THIS IN VIEW, IT IS POSSIBLE THAT A REDUCTION IN WEIGHT MAY LEAD TO A DECREASE IN INFLAMMATION, RESULTING IN CVD RISK REDUCTION, AND BETTER MANAGEMENT OF PATIENTS WITH CVD. LIFESTYLE INTERVENTION HAS BEEN ENDORSED BY SEVERAL HEALTH AUTHORITIES IN PREVENTION AND MANAGEMENT OF CHRONIC DISEASES. A YOGA-BASED LIFESTYLE INTERVENTION APPEARS TO BE A PROMISING OPTION IN REDUCING THE RISK FOR CVD AS WELL AS MANAGEMENT OF PATIENTS WITH CVD AS IT IS SIMPLE TO FOLLOW AND COST-EFFECTIVE WITH HIGH COMPLIANCE. THE EFFICACY OF SUCH LIFESTYLE INTERVENTION PROGRAMMES IS MULTIFACETED, AND IS ACHIEVED VIA REDUCTION IN WEIGHT, OBESITY-RELATED INFLAMMATION AND STRESS, THEREBY CULMINATING INTO RISK REDUCTION TOWARDS SEVERAL CHRONIC DISEASES INCLUDING CVD. IN THIS REVIEW, THE ASSOCIATION BETWEEN OBESITY-RELATED INFLAMMATION AND CVD, AND THE ROLE OF YOGA-BASED LIFESTYLE INTERVENTION IN PREVENTION AND MANAGEMENT OF CVD ARE DISCUSSED.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
5 1988  31 SPECTRAL PARAMETERS OF HRV IN YOGA PRACTITIONERS, ATHLETES AND SEDENTARY MALES. PHYSICAL INACTIVITY IS AN IMPORTANT RISK FACTOR FOR CARDIOVASCULAR MORTALITY AND MORBIDITY. EXERCISE IS CONSIDERED AN ACCEPTABLE METHOD FOR IMPROVING AND MAINTAINING PHYSICAL AND EMOTIONAL HEALTH. ALTHOUGH YOGA IS HISTORICALLY A SPIRITUAL DISCIPLINE, A GROWING BODY OF EVIDENCE SUPPORTS THE BELIEF THAT YOGA BENEFITS PHYSICAL AND MENTAL HEALTH. THE OBJECTIVE OF THIS STUDY WAS TO EVALUATE HEART RATE VARIABILITY WHICH REFLECTS AUTONOMIC CONTROL OF HEART AMONG YOGA PRACTITIONERS, ATHLETES AND INDIVIDUALS WITH SEDENTARY LIFESTYLE. THE STUDY WAS CARRIED OUT IN THE DEPARTMENTS OF PHYSIOLOGY AT MAMC AGROHA, HISAR AND PT. BD SHARMA PGIMS ROHTAK, HARYANA. THE STUDY GROUP COMPRISED OF 1200 HEALTHY MALE VOLUNTEERS OF 16 TO 55 YEARS OF AGE. THE STUDY GROUP WAS DIVIDED INTO FOUR AGE GROUPS: GROUP A OF AGE 16 TO 25 YEARS; GROUP B OF AGE 26 TO 35 YEARS; GROUP C OF AGE 36 TO 45 YEARS AND GROUP D OF AGE 46 TO 55 YEARS. ALL AGE GROUPS WERE FURTHER DIVIDED INTO THREE CATEGORIES I.E ATHLETE (RUNNER), YOGA (YOGA PRACTITIONERS) AND SEDENTARY IN WHICH INDIVIDUALS WITH SEDENTARY LIFE STYLE WERE INCLUDED. THE BASAL RECORDING OF ECG IN LEAD II WAS DONE FOR 5 MINUTES. THE POLYRITE-D ECG DATA WAS USED FOR ANALYSIS OF HEART RATE VARIABILITY BY FREQUENCY DOMAIN METHOD. TWO SPECTRAL COMPONENTS WERE RECORDED NAMELY HIGH FREQUENCY (HF) COMPONENT (0.15-0.4 HZ), AN INDICATOR OF VAGAL EFFERENT ACTIVITY AND LOW FREQUENCY (LF) COMPONENT (0.04-.15 HZ), REPLICATOR OF COMPOSITE SYMPATHO-VAGAL INTERPLAY. HF COMPONENT IN NORMALIZED UNIT WAS FOUND SIGNIFICANTLY HIGH IN AGE GROUP B AND C IN YOGA PRACTITIONERS AND ATHLETES AS COMPARED TO SEDENTARY INDIVIDUALS AND IN AGE GROUP D SIGNIFICANTLY HIGH IN YOGA PRACTITIONERS AS COMPARED TO ATHLETES AND SEDENTARY INDIVIDUALS. SIGNIFICANTLY DECREASED LF/HF RATIO WAS FOUND IN AGE GROUP B AND C IN YOGA AND ATHLETE SUBJECTS AS COMPARED TO SEDENTARY INDIVIDUALS AND IN AGE GROUP D IN YOGA PRACTITIONERS AS COMPARED TO ATHLETES AND SEDENTARY INDIVIDUALS. THIS INDICATES THAT PARASYMPATHETIC ACTIVITY IS SUBSTANTIALLY GREATER IN YOGA PRACTITIONERS.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                              
6 1640  48 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  565  39 CURRENT STATUS OF YOGA IN MENTAL HEALTH SERVICES. YOGA (DERIVED FROM 'YUJ' WHICH MEANS TO YOKE TOGETHER OR UNITE) HAS BEEN USED FOR MILLENNIA AS A TOOL FOR SELF-IMPROVEMENT, WITH THE ULTIMATE GOAL OF UNITING THE INDIVIDUAL CONSCIOUSNESS WITH THE UNIVERSAL. THE PHYSICAL ELEMENTS OF YOGA, ALTHOUGH SEEN AS NECESSARY IN THE PATH TO ACHIEVE THE GOAL, THEY WERE NOT CONSIDERED AS THE ENDPOINT FOR A PRACTITIONER. SAGE PATANJALI, WHO CODIFIED THE PRACTICES INTO AN EIGHT-LIMBED MODEL (ASHTANGA YOGA) IN THE PATANJALI YOGA SUTRAS, MAKES IT CLEAR THAT THE TARGET OF YOGA IS PRIMARILY THE MIND. HOWEVER, IN THE MODERN WORLD, YOGA PRACTICES HAVE BECOME IMMENSELY POPULAR AS AIDS TO IMPROVE HEALTH. YOGA-BASED PRACTICES ARE BEING EXTENSIVELY USED AS THERAPEUTIC INGREDIENTS, ALONE OR AS ADJUNCTS TO OTHER THERAPIES IN A VARIETY OF DISORDERS, BOTH PHYSICAL AND MENTAL. THERE IS NOW STRONG EVIDENCE TO SUGGEST THAT YOGA-BASED INTERVENTIONS ARE BENEFICIAL IN SEVERAL LIFESTYLE DISORDERS. RECENT RESEARCH HAS ALSO SHOWN SIGNIFICANT BENEFITS IN MENTAL DISORDERS SUCH AS DEPRESSION, ANXIETY, AND PSYCHOSIS. THIS PAPER DISCUSSES THE PLACE OF YOGA AS ONE OF THE THERAPEUTIC STRATEGIES IN THE HOLISTIC APPROACH TO MENTAL DISORDERS, AND THE CHALLENGES INHERENT TO RESEARCH IN THIS AREA.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
8 2847  47 YOGA, MEDITATION AND MIND-BODY HEALTH: INCREASED BDNF, CORTISOL AWAKENING RESPONSE, AND ALTERED INFLAMMATORY MARKER EXPRESSION AFTER A 3-MONTH YOGA AND MEDITATION RETREAT. THIRTY-EIGHT INDIVIDUALS (MEAN AGE: 34.8 YEARS OLD) PARTICIPATING IN A 3-MONTH YOGA AND MEDITATION RETREAT WERE ASSESSED BEFORE AND AFTER THE INTERVENTION FOR PSYCHOMETRIC MEASURES, BRAIN DERIVED NEUROTROPHIC FACTOR (BDNF), CIRCADIAN SALIVARY CORTISOL LEVELS, AND PRO- AND ANTI-INFLAMMATORY CYTOKINES. PARTICIPATION IN THE RETREAT WAS FOUND TO BE ASSOCIATED WITH DECREASES IN SELF-REPORTED ANXIETY AND DEPRESSION AS WELL AS INCREASES IN MINDFULNESS. AS HYPOTHESIZED, INCREASES IN THE PLASMA LEVELS OF BDNF AND INCREASES IN THE MAGNITUDE OF THE CORTISOL AWAKENING RESPONSE (CAR) WERE ALSO OBSERVED. THE NORMALIZED CHANGE IN BDNF LEVELS WAS INVERSELY CORRELATED WITH BSI-18 ANXIETY SCORES AT BOTH THE PRE-RETREAT (R = 0.40, P < 0.05) AND POST-RETREAT (R = 0.52, P < 0.005) SUCH THAT THOSE WITH GREATER ANXIETY SCORES TENDED TO EXHIBIT SMALLER PRE- TO POST-RETREAT INCREASES IN PLASMA BDNF LEVELS. IN LINE WITH A HYPOTHESIZED DECREASE IN INFLAMMATORY PROCESSES RESULTING FROM THE YOGA AND MEDITATION PRACTICES, WE FOUND THAT THE PLASMA LEVEL OF THE ANTI-INFLAMMATORY CYTOKINE INTERLEUKIN-10 WAS INCREASED AND THE PRO-INFLAMMATORY CYTOKINE INTERLEUKIN-12 WAS REDUCED AFTER THE RETREAT. CONTRARY TO OUR INITIAL HYPOTHESES, PLASMA LEVELS OF OTHER PRO-INFLAMMATORY CYTOKINES, INCLUDING INTERFERON GAMMA (IFN-GAMMA), TUMOR NECROSIS FACTOR (TNF-ALPHA), INTERLEUKIN-1BETA (IL-1BETA), INTERLEUKIN-6 (IL-6), AND INTERLEUKIN-8 (IL-8) WERE INCREASED AFTER THE RETREAT. GIVEN EVIDENCE FROM PREVIOUS STUDIES OF THE POSITIVE EFFECTS OF MEDITATIVE PRACTICES ON MENTAL FITNESS, AUTONOMIC HOMEOSTASIS AND INFLAMMATORY STATUS, WE HYPOTHESIZE THAT THESE FINDINGS ARE RELATED TO THE MEDITATIVE PRACTICES THROUGHOUT THE RETREAT; HOWEVER, SOME OF THE OBSERVED CHANGES MAY ALSO BE RELATED TO OTHER ASPECTS OF THE RETREAT SUCH AS PHYSICAL EXERCISE-RELATED COMPONENTS OF THE YOGA PRACTICE AND DIET. WE HYPOTHESIZE THAT THE PATTERNS OF CHANGE OBSERVED HERE REFLECT MIND-BODY INTEGRATION AND WELL-BEING. THE INCREASED BDNF LEVELS OBSERVED IS A POTENTIAL MEDIATOR BETWEEN MEDITATIVE PRACTICES AND BRAIN HEALTH, THE INCREASED CAR IS LIKELY A REFLECTION OF INCREASED DYNAMIC PHYSIOLOGICAL AROUSAL, AND THE RELATIONSHIP OF THE DUAL ENHANCEMENT OF PRO- AND ANTI-INFLAMMATORY CYTOKINE CHANGES TO HEALTHY IMMUNOLOGIC FUNCTIONING IS DISCUSSED.	2017	
                                                                     
9  758  26 EFFECT OF SLOW BREATHING ON AUTONOMIC TONE & BAROREFLEX SENSITIVITY IN YOGA PRACTITIONERS. BACKGROUND & OBJECTIVES: SLOW BREATHING INCREASES PARASYMPATHETIC ACTIVITY AND BAROREFLEX SENSITIVITY (BRS) IN HEALTHY INDIVIDUALS, ALSO SIMILARLY OBSERVED IN YOGA PRACTITIONERS. PRANAYAMA WHICH IS AN IMPORTANT COMPONENT OF YOGA WHEN PRACTICED AT A SLOW PACE WAS AT A RESPIRATORY FREQUENCY OF AROUND 0.1 HZ (6 BREATHS/MIN). THEREFORE, IT WAS HYPOTHESIZED THAT YOGA PRACTITIONERS MIGHT HAVE ADAPTED TO SLOW BREATHING. THIS STUDY WAS AIMED TO DECIPHER THE ROLE OF YOGA ON CARDIOVASCULAR VARIABILITY DURING SLOW BREATHING (0.1 HZ) IN YOGA PRACTITIONERS. METHODS: A CROSS-SECTIONAL STUDY WAS UNDERTAKEN IN NAIVE-TO-YOGA INDIVIDUALS (N=40) AND YOGA PRACTITIONERS (N=40) WITH AN AVERAGE AGE OF 31.08 +/- 7.31 AND 29.93 +/- 7.57 YR, RESPECTIVELY. THE ANALYSIS OF HEART RATE VARIABILITY, BLOOD PRESSURE VARIABILITY (BPV) AND BRS DURING SPONTANEOUS AND SLOW BREATHING WAS COMPARED BETWEEN THE TWO GROUPS. RESULTS: DURING SLOW BREATHING, THE HEART RATE (P<0.01) WAS LOWER, RESPIRATORY RATE INTERVAL (P<0.05) AND PNN50 PER CENT (P=0.01) WERE HIGHER, MEAN SYSTOLIC BP (SBP) (P<0.05) AND SDSD (STANDARD DEVIATION OF SUCCESSIVE BEAT TO BEAT SYSTOLIC BLOOD PRESSURE DIFFERENCES) (P<0.01) OF SBP VARIABILITY WERE LOWER WITH SEQUENCE BRS (P<0.001) AND ALPHA LOW FREQUENCY (P<0.01) AND ALPHA HIGH FREQUENCY (P<0.001) OF SPECTRAL BRS WERE HIGHER IN YOGA PRACTITIONERS. INTERPRETATION & CONCLUSIONS: THE PRESENT STUDY INDICATED HIGHER PARASYMPATHETIC ACTIVITY AND BRS WITH LOWER SBP VARIABILITY AT REST AND DURING SLOW BREATHING IN YOGA PRACTITIONERS COMPARED TO NAIVE GROUP. FINDINGS INDICATE THAT THE SHORT-TERM PRACTICE OF SLOW BREATHING COMPLEMENTS THE AUGMENTED PARASYMPATHETIC ACTIVITY AND BRS IN THE YOGA GROUP.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
10 2454  34 YOGA AS A COMPLEMENTARY THERAPY FOR METABOLIC SYNDROME: A NARRATIVE REVIEW. METABOLIC SYNDROME (MS) IS ASSOCIATED WITH A SEDENTARY AND STRESSFUL LIFESTYLE AND AFFECTS UNDERACTIVE PEOPLE DISPROPORTIONATELY. YOGA IS CONSIDERED TO BE A LOW-IMPACT MIND-BODY STRESS-RELIEVING EXERCISE, AND RESEARCHERS ARE INCREASING THEIR FOCUS ON THE BENEFITS OF YOGA FOR MANAGING METABOLIC DISORDERS. IT IS ALSO IMPORTANT FOR PHYSICIANS AND HEALTH CARE PROFESSIONALS TO UNDERSTAND THE THERAPEUTIC EFFICACY OF YOGA INTERVENTION, IN TERMS OF ITS TYPE, DURATION AND FREQUENCY ON VARIOUS MS RISK FACTORS. THE PRESENT REVIEW SUMMARIZES THE CURRENT SCIENTIFIC UNDERSTANDING OF THE EFFECTS OF YOGA ON MS RISK FACTORS SUCH AS GLUCOSE HOMEOSTASIS MARKERS, LIPID PROFILE, ADIPOCYTOKINES AND CARDIOVASCULAR RISK FACTORS, AND DISCUSSES THE POSSIBLE MECHANISMS OF ACTION. MEDLINE, PUBMED, SCOPUS AND COCHRANE LIBRARY WERE SEARCHED FROM THEIR INCEPTION UP TO DECEMBER 2019, USING THE KEYWORDS "METABOLIC SYNDROME," "DIABETES," "CARDIOVASCULAR DISEASES," "OBESITY" AND "YOGA." THE LITERATURE SUMMARIZED IN THIS REVIEW HAVE SHOWN MIXED EFFECTS OF YOGA ON MS RISK FACTORS AND DO NOT PROVIDE ROBUST EVIDENCE FOR ITS EFFICACY. MORE RIGOROUS RESEARCH AND WELL-DESIGNED TRIALS THAT HAVE A HIGHER STANDARD OF METHODOLOGY AND EVALUATE YOGA'S LONG-TERM IMPACTS ON MS ARE NEEDED. UNDERSTANDING YOGA'S BIOCHEMICAL AND MOLECULAR MECHANISMS OF ACTION ON VARIOUS METABOLIC PATHWAYS IS ALSO NEEDED.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
11   93  35 A NARRATIVE REVIEW OF YOGA AND MINDFULNESS AS COMPLEMENTARY THERAPIES FOR ADDICTION. THIS PAPER REVIEWS THE PHILOSOPHICAL ORIGINS, CURRENT SCIENTIFIC EVIDENCE, AND CLINICAL PROMISE OF YOGA AND MINDFULNESS AS COMPLEMENTARY THERAPIES FOR ADDICTION. HISTORICALLY, THERE ARE EIGHT ELEMENTS OF YOGA THAT, TOGETHER, COMPRISE ETHICAL PRINCIPLES AND PRACTICES FOR LIVING A MEANINGFUL, PURPOSEFUL, MORAL AND SELF-DISCIPLINED LIFE. TRADITIONAL YOGA PRACTICES, INCLUDING POSTURES AND MEDITATION, DIRECT ATTENTION TOWARD ONE'S HEALTH, WHILE ACKNOWLEDGING THE SPIRITUAL ASPECTS OF ONE'S NATURE. MINDFULNESS DERIVES FROM ANCIENT BUDDHIST PHILOSOPHY, AND MINDFULNESS MEDITATION PRACTICES, SUCH AS GENTLE HATHA YOGA AND MINDFUL BREATHING, ARE INCREASINGLY INTEGRATED INTO SECULAR HEALTH CARE SETTINGS. CURRENT THEORETICAL MODELS SUGGEST THAT THE SKILLS, INSIGHTS, AND SELF-AWARENESS LEARNED THROUGH YOGA AND MINDFULNESS PRACTICE CAN TARGET MULTIPLE PSYCHOLOGICAL, NEURAL, PHYSIOLOGICAL, AND BEHAVIORAL PROCESSES IMPLICATED IN ADDICTION AND RELAPSE. A SMALL BUT GROWING NUMBER OF WELL-DESIGNED CLINICAL TRIALS AND EXPERIMENTAL LABORATORY STUDIES ON SMOKING, ALCOHOL DEPENDENCE, AND ILLICIT SUBSTANCE USE SUPPORT THE CLINICAL EFFECTIVENESS AND HYPOTHESIZED MECHANISMS OF ACTION UNDERLYING MINDFULNESS-BASED INTERVENTIONS FOR TREATING ADDICTION. BECAUSE VERY FEW STUDIES HAVE BEEN CONDUCTED ON THE SPECIFIC ROLE OF YOGA IN TREATING OR PREVENTING ADDICTION, WE PROPOSE A CONCEPTUAL MODEL TO INFORM FUTURE STUDIES ON OUTCOMES AND POSSIBLE MECHANISMS. ADDITIONAL RESEARCH IS ALSO NEEDED TO BETTER UNDERSTAND WHAT TYPES OF YOGA AND MINDFULNESS-BASED INTERVENTIONS WORK BEST FOR WHAT TYPES OF ADDICTION, WHAT TYPES OF PATIENTS, AND UNDER WHAT CONDITIONS. OVERALL, CURRENT FINDINGS INCREASINGLY SUPPORT YOGA AND MINDFULNESS AS PROMISING COMPLEMENTARY THERAPIES FOR TREATING AND PREVENTING ADDICTIVE BEHAVIORS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
12 1319  29 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.

13 1927  38 ROLE OF YOGA IN CARDIAC DISEASE AND REHABILITATION. PURPOSE: CARDIOVASCULAR DISEASE CONTINUES TO BE THE LEADING CAUSE OF MORBIDITY AND MORTALITY AROUND THE WORLD. YOGA, A COMBINATION OF PHYSICAL POSTURES (ASANA), BREATHING EXERCISES (PRANAYAMA), AND MEDITATION (DHYANA), HAS GAINED INCREASING RECOGNITION AS A FORM OF MIND-BODY EXERCISE. IN THIS NARRATIVE REVIEW, WE INTENDED TO REVIEW THE EMERGING EVIDENCE ASSESSING THE PHYSIOLOGIC AND CLINICAL EFFECTS OF YOGA ON THE CARDIOVASCULAR SYSTEM AND THE POTENTIAL ROLE OF YOGA AS A COMPONENT OF COMPREHENSIVE CARDIAC REHABILITATION. METHODS: WE SEARCHED PUBMED, GOOGLE SCHOLAR, EMBASE, AND COCHRANE DATABASES FOR LITERATURE RELATED TO CARDIOVASCULAR EFFECTS OF YOGA FROM INCEPTION UP UNTIL 2017. RESULTS: YOGA HAS BEEN SHOWN TO HAVE FAVORABLE EFFECTS ON SYSTEMIC INFLAMMATION, STRESS, THE CARDIAC AUTONOMIC NERVOUS SYSTEM, AND TRADITIONAL AND EMERGING CARDIOVASCULAR RISK FACTORS. CONCLUSIONS: YOGA HAS SHOWN PROMISE AS A USEFUL LIFESTYLE INTERVENTION THAT CAN BE INCORPORATED INTO CARDIOVASCULAR DISEASE MANAGEMENT ALGORITHMS. ALTHOUGH MANY INVESTIGATORS HAVE REPORTED THE CLINICAL BENEFITS OF YOGA IN REDUCING CARDIOVASCULAR EVENTS, MORBIDITY, AND MORTALITY, EVIDENCE SUPPORTING THESE CONCLUSIONS IS SOMEWHAT LIMITED, THEREBY EMPHASIZING THE NEED FOR LARGE, WELL-DESIGNED RANDOMIZED TRIALS THAT MINIMIZE BIAS AND METHODOLOGICAL DRAWBACKS.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
14 2449  21 YOGA AND THE INTERPLAY BETWEEN ATTENTIONAL LOAD AND EMOTION INTERFERENCE. THIS STUDY COMPARED 45 YOGA PRACTITIONERS (M AGE = 29.7 YR., SD = 6.4) AND 45 MATCHED CONTROLS (M AGE = 29.3 YR., SD = 6.2) ON THE PERFORMANCE OF A BEHAVIORAL TASK THAT ASSESSED NEGATIVE EMOTION INTERFERENCE DURING A HIGH- AND A LOW-ATTENTIONAL DEMAND CONDITION, AS WELL AS ON STATE AND TRAIT ANXIETY SCORES. OUTCOMES WERE ALSO COMPARED BETWEEN BEGINNER AND ADVANCED PRACTITIONERS. FOR THE BEHAVIORAL TASK, THE FINAL SAMPLE COMPRISED 36 YOGA AND 38 CONTROL PARTICIPANTS. THE YOGA GROUP PRESENTED LOWER EMOTION INTERFERENCE IN THE HIGH ATTENTIONAL CONDITION, COMPARED TO THE LOW ATTENTIONAL CONDITION; RATED EMOTIONAL IMAGES AS LESS UNPLEASANT, COMPARED TO CONTROLS; AND REPORTED LOWER STATE AND TRAIT ANXIETY SCORES RELATIVE TO CONTROLS. ALSO, EMOTION INTERFERENCE IN THE LOW ATTENTIONAL CONDITION WAS LOWER AMONG ADVANCED PRACTITIONERS AND STATE ANXIETY WAS LOWER AMONG PRACTITIONERS ATTENDING MORE THAN TWO WEEKLY YOGA CLASSES. THE RESULTS SUGGESTED THAT YOGA MAY HELP IMPROVE SELF-REGULATORY SKILLS AND LOWER ANXIETY. THE PSYCHOLOGICAL MECHANISMS UNDERLYING THE RELATIONSHIP BETWEEN YOGA AND EMOTION REGULATION SHOULD BE FURTHER INVESTIGATED IN LONGITUDINAL STUDIES.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
15 1936  23 ROLE OF YOGA IN THE PREVENTION AND MANAGEMENT OF VARIOUS CARDIOVASCULAR DISEASES AND THEIR RISK FACTORS: A COMPREHENSIVE SCIENTIFIC EVIDENCE-BASED REVIEW. CARDIOVASCULAR DISEASES (CVDS) ARE A GROUP OF DISORDERS OF THE HEART AND BLOOD VESSELS. CVDS ARE THE LEADING CAUSE OF DEATHS WORLDWIDE. THOUGH YOGA IS GAINING POPULARITY AS A THERAPY, ESPECIALLY IN CVD PATIENTS, THERE IS A LACK OF A COMPREHENSIVE REVIEW REPORTING ITS ROLE IN THE MANAGEMENT OF VARIOUS CVDS AND THEIR RISK FACTORS. THUS, WE PERFORMED A COMPREHENSIVE LITERATURE SEARCH IN THE PUBMED/MEDLINE ELECTRONIC DATABASE. AN AGGREGATE OF 603 ARTICLES PUBLISHED FROM INCEPTION WERE SCREENED AND 85 ARTICLES THAT ARE APPLICABLE WERE REPORTED. THIS REVIEW SUGGESTS THAT YOGA MAY PLAY A ROLE AS AN ADJUVANT IN THE MANAGEMENT OF VARIOUS CVDS AND THEIR RISK FACTORS. HOWEVER, MANY STUDIES HAD A SMALL SAMPLE SIZE, DIFFERENT TYPES AND DURATIONS OF THE YOGA INTERVENTIONS, AND DID NOT PROVIDE THE DETAILS OF MECHANISMS BEHIND THE IMPROVEMENTS. THUS, FURTHER STUDIES ARE WARRANTED TO EXPLORE THE MECHANISMS OF THE IMPACTS OF YOGA.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
16 1590  21 MEDITATION AND YOGA CAN MODULATE BRAIN MECHANISMS THAT AFFECT BEHAVIOR AND ANXIETY-A MODERN SCIENTIFIC PERSPECTIVE. MEDITATION AND YOGA TECHNIQUES ARE RECEIVING INCREASED ATTENTION THROUGHOUT THE WORLD, DUE TO THE ACCUMULATION OF EVIDENCE BASED RESEARCH THAT PROVES THE DIRECT AND INDIRECT BENEFITS OF SUCH PRACTICES. BASED ON STUDIES CONDUCTED SO FAR, IT HAS BEEN FOUND THAT THE PRACTICE OF MEDITATION TRIGGERS NEUROTRANSMITTERS THAT MODULATE PSYCHOLOGICAL DISORDERS SUCH AS ANXIETY. THIS PAPER WILL REVIEW THE PSYCHOLOGICAL EFFECTS OF THE PRACTICE OF MEDITATION, THE ROLE OF NEUROTRANSMITTERS, AND STUDIES USING EEG AND FMRI.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
17 1596  24 MEDITATION HAS STRONGER RELATIONSHIPS WITH MINDFULNESS, KUNDALINI, AND MYSTICAL EXPERIENCES THAN YOGA OR PRAYER. CONTEMPLATIVE PRACTICES CAN HAVE PROFOUND EFFECTS ON MINDFULNESS AND ON PHYSICAL AND SENSORY AND MYSTICAL EXPERIENCES. INDIVIDUALS WHO SELF-REPORTED MEDITATION, YOGA, CONTEMPLATIVE PRAYER, OR A COMBINATION OF PRACTICES AND THEIR PATTERNS OF PRACTICE WERE COMPARED FOR MINDFULNESS, KUNDALINI EFFECTS, AND MYSTICAL EXPERIENCES. THE RESULTS SUGGEST THAT THE AMOUNT OF PRACTICE BUT NOT THE PATTERN AND SOCIAL CONDITIONS OF PRACTICE INFLUENCES MINDFULNESS AND POSSIBLY MYSTICAL EXPERIENCES. MEDITATION, YOGA, CONTEMPLATIVE PRAYER, OR A COMBINATION OF PRACTICES ALL WERE FOUND TO BE ASSOCIATED WITH ENHANCEMENTS OF MINDFULNESS, KUNDALINI EFFECTS, AND MYSTICAL EXPERIENCES, BUT MEDITATION HAD PARTICULARLY STRONG ASSOCIATIONS AND MAY BE THE BASIS OF THE ASSOCIATIONS OF YOGA AND PRAYER WITH THESE OUTCOMES. THE RESULTS FURTHER SUGGEST THAT THE PRIMARY ASSOCIATION OF CONTEMPLATIVE PRACTICES IS WITH THE REAL TIME AWARENESS AND APPRECIATION OF SENSORY AND PERCEPTUAL EXPERIENCES WHICH MAY BE THE INTERMEDIARY BETWEEN DISPARATE PRACTICES AND MINDFULNESS, KUNDALINI EFFECTS, AND MYSTICAL EXPERIENCES.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
18 1934  31 ROLE OF YOGA IN STRESS MANAGEMENT. THE STATE OF THE MIND AND THAT OF THE BODY ARE INTIMATELY RELATED. IF THE MIND IS RELAXED, THE MUSCLES IN THE BODY WILL ALSO BE RELAXED. STRESS PRODUCES A STATE OF PHYSICAL AND MENTAL TENSION. YOGA, DEVELOPED THOUSANDS OF YEARS AGO, IS RECOGNIZED AS A FORM OF MIND-BODY MEDICINE. IN YOGA, PHYSICAL POSTURES AND BREATHING EXERCISES IMPROVE MUSCLE STRENGTH, FLEXIBILITY, BLOOD CIRCULATION AND OXYGEN UPTAKE AS WELL AS HORMONE FUNCTION. IN ADDITION, THE RELAXATION INDUCED BY MEDITATION HELPS TO STABILIZE THE AUTONOMIC NERVOUS SYSTEM WITH A TENDENCY TOWARDS PARASYMPATHETIC DOMINANCE. PHYSIOLOGICAL BENEFITS WHICH FOLLOW, HELP YOGA PRACTITIONERS BECOME MORE RESILIENT TO STRESSFUL CONDITIONS AND REDUCE A VARIETY OF IMPORTANT RISK FACTORS FOR VARIOUS DISEASES, ESPECIALLY CARDIO-RESPIRATORY DISEASES.	2004	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
19 2516  25 YOGA CLINICAL RESEARCH REVIEW. IN THIS PAPER RECENT RESEARCH IS REVIEWED ON THE EFFECTS OF YOGA POSES ON PSYCHOLOGICAL CONDITIONS INCLUDING ANXIETY AND DEPRESSION, ON PAIN SYNDROMES, CARDIOVASCULAR, AUTOIMMUNE AND IMMUNE CONDITIONS AND ON PREGNANCY. FURTHER, THE PHYSIOLOGICAL EFFECTS OF YOGA INCLUDING DECREASED HEARTRATE AND BLOOD PRESSURE AND THE PHYSICAL EFFECTS INCLUDING WEIGHT LOSS AND INCREASED MUSCLE STRENGTH ARE REVIEWED. FINALLY, POTENTIAL UNDERLYING MECHANISMS ARE PROPOSED INCLUDING THE STIMULATION OF PRESSURE RECEPTORS LEADING TO ENHANCED VAGAL ACTIVITY AND REDUCED CORTISOL. THE REDUCTION IN CORTISOL, IN TURN, MAY CONTRIBUTE TO POSITIVE EFFECTS SUCH AS ENHANCED IMMUNE FUNCTION AND A LOWER PREMATURITY RATE.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
20 1871  27 RANGE OF YOGA INTENSITIES FROM SAVASANA TO SWEATING: A SYSTEMATIC REVIEW. BACKGROUND: THERE IS LIMITED RESEARCH EXAMINING THE INTENSITY OF YOGA AND INTENSITY VARIATIONS BETWEEN DIFFERENT STYLES. THE PURPOSE OF THIS REVIEW IS TO EXAMINE THE INTENSITY OF YOGA BASED ON DIFFERENT PHYSIOLOGIC RESPONSES BOTH BETWEEN DIFFERENT YOGA STYLES AND WITHIN STYLES OF YOGA. METHODS: ARTICLES WERE SEARCHED FOR ON THE PUBMED DATABASE IN EARLY 2019. INCLUSION CRITERIA WERE AS FOLLOWS: (1) WRITTEN IN ENGLISH, (2) CITE A SPECIFIC STYLE OF YOGA AND INCLUDE WHOLE YOGA SESSION, AND (3) MEASURE METABOLIC OR HEART RATE RESPONSE. RESULTS: TEN ARTICLES WERE REVIEWED; ARTICLES REPORTED OXYGEN CONSUMPTION (N = 1), HEART RATE (N = 4), OR BOTH VARIABLES (N = 5). YOGA STYLES ASSESSED INCLUDED ASHTANGA (N = 2), BIKRAM (N = 3), GENTLE (N = 1), HATHA (N = 3), IYENGAR (N = 1), POWER (N = 1), AND VINYASA (N = 1). OXYGEN CONSUMPTION COMMONLY CATEGORIZED YOGA AS A LIGHT-INTENSITY ACTIVITY, WHILE HEART RATE RESPONSES CLASSIFIED DIFFERENT YOGA INTO MULTIPLE INTENSITIES. CONCLUSION: THIS REVIEW DEMONSTRATES THAT LARGE DIFFERENCES IN INTENSITY CLASSIFICATIONS ARE OBSERVED BETWEEN DIFFERENT STYLES OF YOGA. FURTHERMORE, METABOLIC AND HEART RATE RESPONSES CAN BE VARIABLE, LEADING TO INCONSISTENT INTENSITY CLASSIFICATIONS. THIS IS LIKELY DUE TO THEIR NONLINEAR RELATIONSHIP DURING YOGA. THUS, IT IS IMPERATIVE THAT THE FIELD OF YOGA RESEARCH WORKS TOGETHER TO CREATE A STANDARD FOR REPORTING YOGA.	2020
