YOGA HAS BEEN DESCRIBED AS HAVING A BENEFICIAL EFFECT ON HEART RATE VARIABILITY (HRV), A MARKER FOR CARDIAC AUTONOMIC ACTIVITY WHICH CAN ASSESS CARDIOVASCULAR RISK, IN VARIOUS POPULATIONS. AIM: THE AIM OF THE STUDY WAS TO STUDY THE EFFECT OF 3-MONTH LONG YOGA PRACTICE ON HRV IN EARLY POSTMENOPAUSAL WOMEN. SETTINGS AND DESIGN: A PROSPECTIVE LONGITUDINAL STUDY OF 67 WOMEN WITHIN 5 YEARS OF MENOPAUSE BETWEEN 45 AND 60 YEARS OF AGE ATTENDING MENOPAUSE CLINIC OF DEPARTMENT OF GYNAECOLOGY, SUCHETA KRIPLANI HOSPITAL FULFILLING INCLUSION AND EXCLUSION CRITERIA AND CONSENTING WERE ENROLLED FOR THE STUDY. SUBJECTS AND METHODS: HRV OF 37 CASES (YOGA GROUP) AND 30 CONTROLS (NON-YOGA GROUP) WAS RECORDED PRE AND 3-MONTH POSTINTERVENTION. STATISTICAL ANALYSIS USED: GRAPHPAD PRISM VERSION 5 SOFTWARE WAS USED. VALUES ARE A MEAN AND STANDARD ERROR OF MEAN. STATISTICAL SIGNIFICANCE WAS SET UP AT P < 0.05. RESULTS: IN HRV, FREQUENCY DOMAIN ANALYSIS SHOWED A SIGNIFICANT FALL IN LOW FREQUENCY (LF) IN NORMALIZED UNITS (NU) AND LF: HIGH FREQUENCY (HF) RATIO AND SIGNIFICANT RISE IN HF IN NU IN THE YOGA GROUP (DEPICTING PARASYMPATHETIC DOMINANCE) AGAINST A SIGNIFICANT RISE IN LF (NU) AND LF: HF RATIO AND SIGNIFICANT FALL IN HF (NU) IN NON-YOGA GROUP (INDICATING SYMPATHETIC DOMINANCE). TIME DOMAIN ANALYSIS SHOWED A SIGNIFICANT DECREASE IN STANDARD DEVIATION OF NN INTERVALS IN NON-YOGA GROUP AGAINST NONSIGNIFICANT CHANGES IN YOGA GROUP INDICATING DETERIORATION IN PARASYMPATHETIC ACTIVITY IN NON-YOGA GROUP. CONCLUSIONS: THREE-MONTH LONG YOGA PRACTICE IMPROVED HRV IN EARLY POSTMENOPAUSAL WOMEN SIGNIFICANTLY AND HAS THE POTENTIAL TO ATTENUATE THE CVD RISK IN POSTMENOPAUSAL WOMEN.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                               
2  906  32 EFFECTIVENESS OF APP-BASED YOGA OF IMMORTALS (YOI) INTERVENTION FOR INSOMNIA IN ASIAN POPULATION DURING PANDEMIC RESTRICTIONS. THE CORONAVIRUS DISEASE 2019 (COVID-19) PANDEMIC CREATED SIGNIFICANT PSYCHOLOGICAL CHALLENGES WORLDWIDE, INCLUDING STRESS, EMOTIONAL DISTRESS, AND INSOMNIA. IN ADDITION, SOCIAL DISTANCING, TRAVEL RESTRICTIONS, AND SPREAD OF DISEASE HAVE RESULTED IN UNIQUE CHALLENGES, CREATING BARRIERS TO HEALTHCARE ACCESS. COMPARED TO THE RATE PRIOR TO THE COVID-19 PANDEMIC, A SIGNIFICANT INCREASE IN CLINICAL INSOMNIA RATES HAVE BEEN REPORTED. WITH WELL-KNOWN LIMITATIONS OF CURRENTLY ESTABLISHED TREATMENTS (E.G., COGNITIVE BEHAVIORAL THERAPY-INSOMNIA (CBT-I), PHARMACOTHERAPY), THERE IS A NEED TO EXPLORE OTHER EFFECTIVE AND SAFE TREATMENT MODALITIES TO TREAT INSOMNIA, ESPECIALLY THOSE THAT CAN BE USED REMOTELY. THE PURPOSE OF THIS STUDY IS TO ASSESS THE EFFECTIVENESS OF APP-BASED INTERVENTION TO TREAT INSOMNIA IN THE CURRENT ERA OF THE COVID-19 PANDEMIC (USING THE YOGA OF IMMORTALS (YOI) APP). THIS PROSPECTIVE COHORT STUDY WAS APPROVED BY THE INSTITUTIONAL REVIEW BOARD. ALL PARTICIPANTS IN THIS STUDY WERE ASKED TO COMPLETE AN ONLINE SURVEY INCLUDING DEMOGRAPHIC DATA AND VALIDATED INSOMNIA SEVERITY INDEX (ISI) AT BASELINE (15 MAY 2020), 4 WEEKS, AND 8 WEEKS AFTER STARTING THE YOI INTERVENTION. SURVEY DATA WAS EXPORTED USING MICROSOFT EXCEL. STATISTICAL ANALYSIS WAS DONE USING THE GRAPHPAD PRISM 8. YOI INTERVENTION SIGNIFICANTLY IMPROVED THE MEAN ISI SCORES IN ALL CATEGORIES OF INSOMNIA (SEVERE, MODERATE, AND SUBTHRESHOLD) AT EACH FOLLOW-UP (P </= 0.0001). THE IMPROVEMENT WAS SIGNIFICANT AMONG ALL AGE GROUPS AND IN BOTH GENDERS. IN OUR STUDY, YOI WAS A NOVEL AND EFFECTIVE INTERVENTION FOR IMPROVING INSOMNIA SYMPTOMS AND MAY BE A NEW ADDITION TO THE ARMAMENTARIUM OF INSOMNIA MANAGEMENT. BEING APP-BASED, THIS HAS POTENTIAL WIDER APPLICABILITY, ESPECIALLY DURING THE CURRENT COVID-19 PANDEMIC.	2021	
                                                                                                                                                                                                                                                                                                                                                                
3 1578  59 MEASUREMENT OF THE EFFECT OF ISHA YOGA ON CARDIAC AUTONOMIC NERVOUS SYSTEM USING SHORT-TERM HEART RATE VARIABILITY. BACKGROUND: BENEFICIAL EFFECTS OF YOGA HAVE BEEN POSTULATED TO BE DUE TO MODULATION OF THE AUTONOMIC NERVOUS SYSTEM. OBJECTIVE: TO ASSESS THE EFFECT OF ISHA YOGA PRACTICES ON CARDIOVASCULAR AUTONOMIC NERVOUS SYSTEM THROUGH SHORT-TERM HEART RATE VARIABILITY (HRV). DESIGN OF THE STUDY: SHORT-TERM HRV OF LONG-TERM REGULAR HEALTHY 14 (12 MALES AND 2 FEMALES) ISHA YOGA PRACTITIONERS WAS COMPARED WITH THAT OF AGE- AND GENDER-MATCHED 14 (12 MALES AND 2 FEMALES) NON-YOGA PRACTITIONERS. METHODS AND MATERIALS: ECG LEAD II AND RESPIRATORY MOVEMENTS WERE RECORDED IN BOTH GROUPS USING POLYRITE DURING SUPINE REST FOR 5 MIN AND CONTROLLED DEEP BREATHING FOR 1 MINUTE. FREQUENCY DOMAIN ANALYSIS [RR INTERVAL IS THE MEAN OF DISTANCE BETWEEN SUBSEQUENT R WAVE PEAKS IN ECG], LOW FREQUENCY (LF) POWER, HIGH FREQUENCY (HF) POWER, LF NORMALIZED UNITS (NU), HF NU, LF/HF RATIO] AND TIME DOMAIN ANALYSIS [STANDARD DEVIATION OF NORMAL TO NORMAL INTERVAL (SDNN), SQUARE OF MEAN SQUARED DIFFERENCE OF SUCCESSIVE NORMAL TO NORMAL INTERVALS (RMSSD), NORMAL TO NORMAL INTERVALS WHICH ARE DIFFERING BY 50 MS (NN50), AND PERCENTAGE OF NN50 (PNN50)] OF HRV VARIABLES WERE ANALYZED FOR SUPINE REST. TIME DOMAIN ANALYSIS WAS RECORDED FOR DEEP BREATHING. RESULTS: RESULTS SHOWED STATISTICALLY SIGNIFICANT DIFFERENCES BETWEEN ISHA YOGA PRACTITIONERS AND CONTROLS IN BOTH FREQUENCY AND TIME DOMAIN ANALYSES OF HRV INDICES, WITH NO DIFFERENCE IN RESTING HEART RATE BETWEEN THE GROUPS. CONCLUSIONS: PRACTITIONERS OF ISHA YOGA SHOWED WELL-BALANCED BENEFICIAL ACTIVITY OF VAGAL EFFERENTS, AN OVERALL INCREASED HRV, AND SYMPATHOVAGAL BALANCE, COMPARED TO NON-YOGA PRACTITIONERS DURING SUPINE REST AND DEEP BREATHING.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
4  350  59 ASSESSMENT OF CARDIAC AUTONOMIC TONE FOLLOWING LONG SUDARSHAN KRIYA YOGA IN ART OF LIVING PRACTITIONERS. OBJECTIVE: THE BREATHING PROCESSES ARE KNOWN TO MODULATE CARDIAC AUTONOMIC TONE AND IMPROVE PSYCHOLOGICAL STATUS. WE INVESTIGATED CARDIAC AUTONOMIC TONE FOLLOWING LONG SUDARSHAN KRIYA YOGA (SKY) USING HEART RATE VARIABILITY (HRV) AND SKIN CONDUCTANCE LEVEL (SCL). METHODS: THIRTY HEALTHY VOLUNTEERS (AGE 28.3 +/- 8.4 YEARS; 23 M: 7 F) PARTICIPATED IN THE STUDY. ELECTROCARDIOGRAM (ECG) AND SCL WERE RECORDED FOR 5 MIN EACH, BEFORE AND AFTER LONG SKY. LONG SKY IS A COMBINATION OF PRANAYAMA AND CYCLIC RHYTHMIC BREATHING AND IS PERFORMED BY FOLLOWING THE GUIDED AUDIO INSTRUCTIONS. HRV ANALYSIS WAS USED FOR THE ASSESSMENT OF CARDIAC AUTONOMIC TONE. TIME AND FREQUENCY DOMAIN PARAMETERS OF HRV WERE CALCULATED BY USING RR INTERVAL OF ECG. SCL WAS ACQUIRED USING GALVANIC SKIN RESPONSE (GSR) AMPLIFIER OF POWERLAB IN MICROSEIMENS (MUS). RESULTS: TIME DOMAIN PARAMETERS OF HRV, INCLUDING MEAN RR INTERVAL (P = 0.000), RESPIRATORY SINUS ARRHYTHMIA (RSA) (P = 0.037), STANDARD DEVIATION OF ALL NN INTERVALS (SDNN) (P = 0.013), NN50 COUNT DIVIDED BY THE TOTAL NUMBER OF ALL NN INTERVALS (PNN50) (P = 0.004), AND SQUARE ROOT OF THE MEAN OF THE SUM OF THE SQUARES OF DIFFERENCES BETWEEN ADJACENT NN INTERVALS (RMSSD) (P = 0.002) INCREASED, AND MEAN HEART RATE DECREASED (P = 0.000) FOLLOWING LONG SKY. IN FREQUENCY DOMAIN ANALYSIS, POWER OF LOW-FREQUENCY (LF) COMPONENT (P = 0.010) AND LF/HF RATIO (P = 0.008) DECREASED SIGNIFICANTLY, WHEREAS POWER OF HIGH FREQUENCY (HF) SIGNIFICANTLY INCREASED (P = 0.010). SCL DECREASED FOLLOWING LONG SKY, ALTHOUGH IT DID NOT ATTAIN STATISTICAL SIGNIFICANCE. CONCLUSIONS: THE RESULTS SUGGEST THAT LONG SKY INDUCES SIGNIFICANT OSCILLATIONS IN CARDIAC AUTONOMIC TONE. PARASYMPATHETIC ACTIVITY INCREASES AND SYMPATHETIC ACTIVITY DECREASES AND SYMPATHOVAGAL BALANCE IMPROVES FOLLOWING LONG SKY. DECREASE IN SYMPATHETIC ACTIVITY IS ALSO DEMONSTRATED BY DECREASE IN CONDUCTANCE ALTHOUGH IT DID NOT REACH STATISTICAL SIGNIFICANCE. FROM THIS STUDY IT CAN BE CONCLUDED THAT LONG SKY HAS A BENEFICIAL EFFECT ON CARDIAC AUTONOMIC TONE, AND PSYCHOPHYSIOLOGICAL RELAXATION. IT MAY SERVE AS A TOOL TO IMPROVE HRV, WHICH IS THE MARKER OF CARDIOVASCULAR HEALTH.	2017	

5 2730  31 YOGA OF IMMORTALS INTERVENTION REDUCES SYMPTOMS OF DEPRESSION, INSOMNIA AND ANXIETY. BACKGROUND: DEPRESSION, ANXIETY, AND DISORDERED SLEEP ARE SOME COMMON SYMPTOMS ASSOCIATED WITH SUB-OPTIMAL MENTAL HEALTH. DURING THE COVID-19 PANDEMIC, MENTAL HEALTH ISSUES HAVE GROWN INCREASINGLY MORE PREVALENT IN THE POPULATION. DUE TO SOCIAL DISTANCING AND OTHER LIMITATIONS DURING THE PANDEMIC, THERE IS A NEED FOR HOME-BASED, FLEXIBLE INTERVENTIONS THAT CAN IMPROVE MENTAL HEALTH. THE YOGA OF IMMORTALS (YOI) MOBILE APPLICATION PROVIDES A STRUCTURED INTERVENTION THAT CAN BE USED ON ANY MOBILE DEVICE AND APPLIED FROM THE USER'S HOME. METHODS: A TOTAL OF 1,505 PARTICIPANTS WERE ENROLLED IN THE STUDY AND USED THE YOI APP FOR AN 8-WEEK PERIOD. PARTICIPANTS WERE ASKED TO FILL OUT THREE QUESTIONNAIRES: THE PATIENT HEALTH QUESTIONNAIRE, 8 ITEMS (PHQ-8), THE GENERALIZED ANXIETY DISORDER QUESTIONNAIRE (GAD-7) AND THE INSOMNIA SEVERITY INDEX (ISI). THESE THREE ITEMS WERE COMPLETED BY 1,297 PARTICIPANTS A TOTAL OF FOUR TIMES: BEFORE STARTING YOI, TWO MORE TIMES DURING USE, AND A FOURTH TIME AFTER THE 8-WEEK USAGE PERIOD. CHANGES IN PHQ8, GAD7 AND ISI IN PARTICIPANTS WERE COMPARED TO A CONTROL GROUP, WHO DID NOT USE THE YOI APP BUT COMPLETED ALL QUESTIONNAIRES (590 CONTROLS FINISHED ALL QUESTIONNAIRES). RESULTS: PARTICIPANTS REPORTED SIGNIFICANT DECREASES IN DEPRESSION AND ANXIETY-RELATED SYMPTOMS. COMPARED TO BASELINE, PHQ-8 SCORES DECREASED 50% ON AVERAGE AFTER THE 8-WEEK PERIOD. GAD-7 SCORES ALSO DECREASED BY 40-50% ON AVERAGE, AND ISI SCORES DECREASED BY 50%. THESE CHANGES WERE SIGNIFICANTLY GREATER (P < 0.05) THAN THAT OBSERVED IN THE CONTROL GROUP. PARTICIPANTS WHO REPORTED A PREVIOUS DIAGNOSIS OF DEPRESSION AND GENERALIZED ANXIETY REPORTED SIGNIFICANTLY LARGER DECREASES IN PHQ-8 AND GAD-7 AS COMPARED TO PARTICIPANTS WITH NO PRIOR DIAGNOSIS (P < 0.05). CONCLUSIONS: REGULAR USE OF THE YOI INTERVENTION OVER AN 8-WEEK PERIOD LED TO SIGNIFICANT DECREASES IN SYMPTOMS OF BOTH DEPRESSION AND ANXIETY, AS WELL AS ALLEVIATION OF INSOMNIA.	2021	
                                                                                                                                                                                                                                             
6  780  54 EFFECT OF YOGA AS AN ADD-ON THERAPY IN THE MODULATION OF HEART RATE VARIABILITY IN CHILDREN WITH DUCHENNE MUSCULAR DYSTROPHY. BACKGROUND: DUCHENE MUSCULAR DYSTROPHY (DMD) IS A PROGRESSIVE MUSCULAR DISORDER. CARDIAC DISORDER IS THE SECOND-MOST COMMON CAUSE OF DEATH IN CHILDREN WITH DMD, WITH 10%-20% OF THEM DYING OF CARDIAC FAILURE. HEART RATE VARIABILITY (HRV) IS SHOWN TO BE A PREDICTOR OF CARDIO-AUTONOMIC FUNCTION. PHYSIOTHERAPY (PT) IS ADVISED FOR THESE CHILDREN AS A REGULAR TREATMENT FOR MAINTAINING THEIR FUNCTIONAL STATUS. THE EFFECT OF YOGIC PRACTICES ON THE CARDIO-AUTONOMIC FUNCTIONS HAS BEEN DEMONSTRATED IN VARIOUS NEUROLOGICAL CONDITIONS AND MAY PROVE BENEFICIAL IN DMD. MATERIALS AND METHODS: IN THIS STUDY, 124 PATIENTS WITH DMD WERE RANDOMIZED TO PT ALONE OR PT WITH YOGA INTERVENTION. HOME-BASED PT AND YOGA WERE ADVISED. ADHERENCE WAS SERIALLY ASSESSED AT A FOLLOW-UP INTERVAL OF 3 MONTHS. ERROR-FREE, ELECTROCARDIOGRAM WAS RECORDED IN ALL PATIENTS AT REST IN THE SUPINE POSITION. HRV PARAMETERS WERE COMPUTED IN TIME AND FREQUENCY DOMAINS. HRV WAS RECORDED AT BASELINE AND AT AN INTERVAL OF 3 MONTHS UP TO 1 YEAR. REPEATED-MEASURES ANOVA WAS USED TO ANALYZE LONGITUDINAL FOLLOW-UP AND LEAST SIGNIFICANT DIFFERENCE FOR POST HOC ANALYSIS AND P < 0.05 WAS CONSIDERED STATISTICALLY SIGNIFICANT. RESULTS: IN OUR STUDY, WITH PT PROTOCOL, STANDARD DEVIATION OF NN, ROOT OF SQUARE MEAN OF SUCCESSIVE NN, TOTAL POWER, LOW FREQUENCY, HIGH-FREQUENCY NORMALIZED UNITS (HFNU), AND SYMPATHOVAGAL BALANCE IMPROVED AT VARYING TIME POINTS AND THE IMPROVEMENT LASTED UP FOR 6-9 MONTHS, WHEREAS PT AND YOGA PROTOCOL SHOWED AN IMPROVEMENT IN HFNU DURING THE LAST 3 MONTHS OF THE STUDY PERIOD AND ALL THE OTHER PARAMETERS WERE STABLE UP TO 1 YEAR. THUS, IT IS EVIDENT THAT BOTH THE GROUPS IMPROVED CARDIAC FUNCTIONS IN DMD. HOWEVER, NO SIGNIFICANT DIFFERENCE WAS NOTED IN THE CHANGES OBSERVED BETWEEN THE GROUPS. CONCLUSION: THE INTENSE PT AND PT WITH YOGA, PARTICULARLY HOME-BASED PROGRAM, IS INDEED BENEFICIAL AS A THERAPEUTIC STRATEGY IN DMD CHILDREN TO MAINTAIN AND/OR TO SUSTAIN HRV IN DMD.	2019	
                                                                                                                                                                                       
7  370  43 AUTONOMIC TONE AND BAROREFLEX SENSITIVITY DURING 70 DEGREES HEAD-UP TILT IN YOGA PRACTITIONERS. INTRODUCTION: THE INTERVENTION OF YOGA WAS SHOWN TO IMPROVE THE AUTONOMIC CONDITIONING IN HUMANS EVIDENT FROM THE ENHANCEMENT OF PARASYMPATHETIC ACTIVITY AND BAROREFLEX SENSITIVITY (BRS). FROM THE DOCUMENTED HEALTH BENEFITS OF YOGA, WE HYPOTHESIZED THAT THE EXPERIENCE OF YOGA MAY RESULT IN ADAPTATION TO THE ORTHOSTATIC STRESS DUE TO ENHANCED BRS. AIM: TO DECIPHER THE EFFECTS OF YOGA IN THE MODULATION OF AUTONOMIC FUNCTION DURING ORTHOSTATIC CHALLENGE. MATERIALS AND METHODS: THIS WAS A COMPARATIVE STUDY DESIGN CONDUCTED IN AUTONOMIC FUNCTION TEST LAB, OF THE DEPARTMENT OF PHYSIOLOGY, ALL INDIA INSTITUTE OF MEDICAL SCIENCES, NEW DELHI, INDIA. HEART RATE VARIABILITY (HRV), BLOOD PRESSURE VARIABILITY, AND BRS WERE ANALYZED ON FORTY NAIVE TO YOGA (NY) SUBJECTS AND FORTY YOGA PRACTITIONERS WITH AN AVERAGE AGE OF 31.08 +/- 7.31 YEARS AND 29.93 +/- 7.57 YEARS, RESPECTIVELY. ALL PARTICIPANTS WERE HEALTHY. SEVENTY DEGREES HEAD UP TILT (HUT) WAS USED AS AN INTERVENTION TO EVALUATE THE CARDIOVASCULAR VARIABILITY DURING ORTHOSTATIC CHALLENGE. RESULTS: DURING HUT, THE R-R INTERVAL (P = 0.042), ROOT MEAN SQUARE OF SUCCESIVE R-R INTERVAL DIFFERENCES (RMSSD) (P = 0.039), STANDARD DEVIATION OF INSTANTANEOUS BEAT-TO-BEAT R-R INTERVAL VARIABILITY (SD1) (P = 0.039) OF HRV, AND SEQUENCE BRS (P = 0.017) AND ALPHA LOW FREQUENCY OF SPECTRAL BRS (P = 0.002) WERE HIGHER IN THE YOGA GROUP. THE DELTA DECREASE IN RRI (P = 0.033) AND BRS (P < 0.01) WAS HIGHER IN THE YOGA GROUP THAN THE NY GROUP. CONCLUSION: THE EFFERENT VAGAL ACTIVITY AND BRS WERE HIGHER IN YOGA PRACTITIONERS. THE DELTA CHANGE (DECREASE) IN PARASYMPATHETIC ACTIVITY AND BRS WAS HIGHER, WITH RELATIVELY STABLE SYSTOLIC BLOOD PRESSURE INDICATING AN ADAPTIVE RESPONSE TO ORTHOSTATIC CHALLENGE BY THE YOGA PRACTITIONERS COMPARED TO THE NY GROUP.	2020	
                                                                                                                                                                                                                                                                                                                                                                                           
8 1441  43 INCREASED HEART RATE VARIABILITY BUT NO EFFECT ON BLOOD PRESSURE FROM 8 WEEKS OF HATHA YOGA - A PILOT STUDY. BACKGROUND: YOGA EXERCISES ARE KNOWN TO DECREASE STRESS AND RESTORE AUTONOMIC BALANCE. YET KNOWLEDGE ABOUT THE PHYSIOLOGICAL EFFECTS OF INVERSION POSTURES IS LIMITED. THIS STUDY AIMED TO INVESTIGATE THE EFFECTS OF INVERSION POSTURES (HEAD BELOW THE HEART) ON BLOOD PRESSURE (BP) AND HEART RATE VARIABILITY (HRV). METHODS: TWELVE HEALTHY WOMEN AND MEN TOOK PART IN AN 8-WEEK YOGA PROGRAM (60 MIN ONCE A WEEK). BP WAS MEASURED WITH AN AUTOMATIC OMRON MX3 OSCILLOMETRIC MONITORING DEVICE AND HRV WITH A HOLTER 24-HOUR ECG AT BASELINE AND 8 WEEKS AFTER THE INTERVENTION. RESULTS: THERE WAS NO SIGNIFICANT EFFECT OF INVERSION POSTURES ON BP. NINE OUT OF 12 PARTICIPANTS SHOWED A SIGNIFICANT INCREASE IN HRV (P < 0.05) AT NIGHT (2 HOURS) ON PNN50% (12.7 +/- 12.5 TO 18.2 +/- 13.3). THERE WERE NO SIGNIFICANT CHANGES IN OTHER HRV MEASURES SUCH AS NN50, LF, HF, LF/HF RATIO, LF NORMALIZED UNITS (N.U.), HF N.U. AND RMSSD. CONCLUSION: EIGHT WEEKS OF HATHA YOGA IMPROVED HRV SIGNIFICANTLY WHICH SUGGESTS AN INCREASED VAGAL TONE AND REDUCED SYMPATHETIC ACTIVITY.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
9  873  36 EFFECT OF YOGA THERAPY ON HEART RATE, BLOOD PRESSURE AND CARDIAC AUTONOMIC FUNCTION IN HEART FAILURE. BACKGROUND AND OBJECTIVE: IT IS WELL KNOWN THAT A HALL MARK OF HEART FAILURE IS ADVERSE CHANGES IN AUTONOMIC FUNCTION. ELEVATED BLOOD PRESSURE IS A POWERFUL PREDICTOR OF CONGESTIVE HEART FAILURE AND OTHER CARDIOVASCULAR DISEASE (CVD) OUTCOMES. IN THIS STUDY, WE PLANNED TO EXAMINE THE EFFECTS OF A 12 WEEK YOGA THERAPY ON BLOOD PRESSURE, HEART RATE, HEART RATE VARIABILITY, AND RATE PRESSURE PRODUCT (RPP). METHODS: OUT OF 130 HEART FAILURE PATIENTS RECRUITED FOR THE STUDY, 65 PATIENTS WERE RANDOMLY SELECTED TO RECEIVE 12 WEEK YOGA THERAPY ALONG WITH STANDARD MEDICAL THERAPY (YOGA GROUP). OTHER PATIENTS (N=65) RECEIVED ONLY STANDARD MEDICAL THERAPY (CONTROL GROUP). HEART RATE, BLOOD PRESSURE, CARDIAC AUTONOMIC FUNCTION (BY SHORT-TERM HEART-RATE VARIABILITY ANALYSIS) AND MYOCARDIAL OXYGEN CONSUMPTION (BY RPP) WERE ASSESSED BEFORE AND AFTER 12 WEEKS. IN THE YOGA GROUP, 44 PATIENTS AND IN THE CONTROL GROUP, 48 PATIENTS COMPLETED THE STUDY. RESULTS: THERE WAS A SIGNIFICANT DECREASE IN HEART RATE, BLOOD PRESSURE AND RPP IN YOGA GROUP COMPARED TO CONTROL GROUP. ALSO, LFNU AND LF-HF RATIO DECREASED SIGNIFICANTLY AND HFNU INCREASED SIGNIFICANTLY IN YOGA GROUP COMPARED TO CONTROL GROUP. CONCLUSION: TWELVE-WEEK YOGA THERAPY SIGNIFICANTLY IMPROVED THE PARASYMPATHETIC ACTIVITY AND DECREASED THE SYMPATHETIC ACTIVITY IN HEART FAILURE PATIENTS (NYHA I&II).	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
10 1558  47 LONG-TERM EFFECTS OF HATHA YOGA ON HEART RATE VARIABILITY IN HEALTHY PRACTITIONERS: POTENTIAL BENEFITS FOR CARDIOVASCULAR RISK REDUCTION. HATHA YOGA IS COMMONLY PRACTICED IN WESTERN COUNTRIES AND IS CLAIMED TO REDUCE RISK OF CARDIOVASCULAR DISEASE. THE PURPOSE OF THIS STUDY WAS TO EVALUATE AND COMPARE TIME-DOMAIN AND FREQUENCY-DOMAIN METRICS OF HEART RATE VARIABILITY (HRV) IN HATHA YOGA PRACTITIONERS AND HEALTHY CONTROLS. THIS CROSS-SECTIONAL STUDY, WHICH WAS CONDUCTED AT A REGIONAL UNIVERSITY AND COMMUNITY WELLNESS CENTER, INCLUDED CONVENIENCE SAMPLING OF 19 HATHA YOGA PRACTITIONERS AND 8 HEALTHY CONTROLS. USING A LEAD II ECG SYSTEM, 10 MINUTES OF ELECTROCARDIOGRAM (ECG) RECORDING WAS COLLECTED FOR EACH PARTICIPANT. ARTIFACT-FREE, 5-MINUTE SIGNALS WERE USED TO DERIVE TIME-DOMAIN AND FREQUENCY-DOMAIN MEASURES OF HRV. THE MEAN DURATION OF HATHA YOGA PRACTICE AMONG PRACTITIONERS WAS 11.47 +/- 8 YEARS. DEMOGRAPHIC AND ANTHROPOMETRIC CHARACTERISTICS DID NOT DIFFER SIGNIFICANTLY BETWEEN GROUPS. COMPARED WITH THE CONTROL GROUP, THE YOGA GROUP HAD SIGNIFICANTLY GREATER MEAN HIGH FREQUENCY (HF) POWER (859.2 +/- 1342.1 VS 175.5 +/- 121.1; P = .04) AND MEAN HF NORMALIZED UNITS (NU) (57.0 +/- 16.6 VS 36.7 +/- 13.4; P = .02) AND A SIGNIFICANTLY LOWER LOW FREQUENCY (LF)/HF RATIO (1.1 +/- 0.5 VS 2.2 +/- 1.1; P = .01). NO SIGNIFICANT INTERGROUP DIFFERENCES WERE OBSERVED FOR LF POWER, LF NU, OR ANY TIME-DOMAIN MEASURES OF HRV. THESE RESULTS LACK GENERALIZABILITY DUE TO SMALL SAMPLE SIZE AND LACK OF BLINDED ASSESSMENT OF OUTCOME MEASURES. HATHA YOGA PRACTITIONERS SHOWED PARASYMPATHETIC PREDOMINANCE COMPARED WITH HEALTHY CONTROLS. ANALYZING FREQUENCY-DOMAIN HRV METRICS ENABLES DETECTING CHANGES IN CARDIAC AUTONOMIC FUNCTION EARLIER THAN BY ANALYSIS OF TIME-DOMAIN METRICS. PARASYMPATHETIC PREDOMINANCE DEMONSTRATED IN THE YOGA GROUP SUGGESTS HATHA YOGA PRACTITIONERS MAY BE AT LOWER RISK FOR STRESS-RELATED COMORBIDITIES.	2021	
                                                                                                                                                                                                                                                                                                                                                         
11  297  44 ALTERNATE NOSTRIL BREATHING AT DIFFERENT RATES AND ITS INFLUENCE ON HEART RATE VARIABILITY IN NON PRACTITIONERS OF YOGA. INTRODUCTION: HEART RATE VARIABILITY IS A MEASURE OF MODULATION IN AUTONOMIC INPUT TO THE HEART AND IS ONE OF THE MARKERS OF AUTONOMIC FUNCTIONS. THOUGH THERE ARE MANY STUDIES ON THE LONG TERM INFLUENCE OF BREATHING ON HRV (HEART RATE VARIABILITY) THERE ARE ONLY A FEW STUDIES ON THE IMMEDIATE EFFECT OF BREATHING ESPECIALLY ALTERNATE NOSTRIL BREATHING ON HRV. THIS STUDY FOCUSES ON THE IMMEDIATE EFFECTS OF ALTERNATE NOSTRIL BREATHING AND THE INFLUENCE OF DIFFERENT BREATHING RATES ON HRV. MATERIALS AND METHODS: THE STUDY WAS DONE ON 25 SUBJECTS IN THE AGE GROUP OF 17-35 YEARS. ECG AND RESPIRATION WERE RECORDED BEFORE INTERVENTION AND IMMEDIATELY AFTER THE SUBJECTS WERE ASKED TO PERFORM ALTERNATE NOSTRIL BREATHING FOR FIVE MINUTES. RESULTS: LOW FREQUENCY (LF) WHICH IS A MARKER OF SYMPATHETIC ACTIVITY INCREASED, HIGH FREQUENCY (HF) WHICH IS A MARKER OF PARASYMPATHETIC ACTIVITY DECREASED AND THEIR RATIO LF/HF WHICH IS A MARKER OF SYMPATHO/VAGAL BALANCE INCREASED IMMEDIATELY AFTER 6 AND 12 MINUTES IN COMPARISON TO BASELINE VALUES WHEREAS THERE WAS NO SIGNIFICANT DIFFERENCE IN THE MEANS OF THESE COMPONENTS WHEN BOTH 6 AND 12 MINUTES WERE COMPARED. CONCLUSION: IMMEDIATE EFFECTS OF ALTERNATE NOSTRIL BREATHING ON HRV IN NON PRACTITIONERS OF YOGIC BREATHING ARE VERY DIFFERENT FROM THE LONG TERM INFLUENCE OF YOGIC BREATHING ON HRV WHICH SHOW A PREDOMINANT PARASYMPATHETIC INFLUENCE ON THE HEART.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
12 1317  43 HEART RATE VARIABILITY CHANGES DURING HIGH FREQUENCY YOGA BREATHING AND BREATH AWARENESS. BACKGROUND: PRE AND POST COMPARISON AFTER ONE MINUTE OF HIGH FREQUENCY YOGA BREATHING (HFYB) SUGGESTED THAT THE HFYB MODIFIES THE AUTONOMIC STATUS BY INCREASING SYMPATHETIC MODULATION, BUT ITS EFFECT DURING THE PRACTICE WAS NOT ASSESSED. METHODS: THIRTY-EIGHT MALE VOLUNTEERS WITH GROUP AVERAGE AGE +/- S.D., 23.3 +/- 4.4 YEARS WERE EACH ASSESSED ON TWO SEPARATE DAYS IN TWO SESSIONS, (I) HFYB AND (II) BREATH AWARENESS. EACH SESSION WAS FOR 35 MINUTES, WITH 3 PERIODS, I.E., PRE (5 MINUTES), DURING HFYB OR BREATH AWARENESS (15 MINUTES) AND POST (5 MINUTES). RESULTS: THERE WAS A SIGNIFICANT DECREASE IN NN50, PNN50 AND THE MEAN RR INTERVAL DURING AND AFTER HFYB AND AFTER BREATH AWARENESS, COMPARED TO THE RESPECTIVE 'PRE' VALUES (P < 0.05) (REPEATED MEASURES ANOVA FOLLOWED BY POST-HOC ANALYSIS). THE LF POWER INCREASED AND HF POWER DECREASED DURING AND AFTER BREATH AWARENESS AND LF/HF RATIO INCREASED AFTER BREATH AWARENESS (P < 0.05). CONCLUSION: THE RESULTS SUGGEST THAT THERE WAS REDUCED PARASYMPATHETIC MODULATION DURING AND AFTER HFYB AND INCREASED SYMPATHETIC MODULATION WITH REDUCED PARASYMPATHETIC MODULATION DURING AND AFTER BREATH AWARENESS.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
13 1318  50 HEART RATE VARIABILITY IN CHRONIC LOW BACK PAIN PATIENTS RANDOMIZED TO YOGA OR STANDARD CARE. BACKGROUND: CHRONIC PAIN CAN ALTER THE AUTONOMIC BALANCE WITH INCREASED SYMPATHETIC ACTIVITY REFLECTED IN ALTERED HEART RATE VARIABILITY (HRV). IT HAS BEEN PROPOSED THAT YOGA CAN BE USEFUL TO CORRECT THE AUTONOMIC IMBALANCE IN PATIENTS WITH CHRONIC PAIN WHO HAVE REDUCED HRV. METHODS AND DESIGNS: IN THE PRESENT RANDOMIZED CONTROLLED TRIAL 62 PATIENTS WITH CHRONIC LOW BACK PAIN ASSOCIATED WITH ALTERED ALIGNMENT OF INTERVERTEBRAL DISCS (AGED BETWEEN 20 AND 45 YEARS, 32 MALES) WERE RANDOMIZED TO 2 GROUPS. ONE GROUP RECEIVED YOGA FOR 3 MONTHS WHILE THE OTHER GROUP CARRIED OUT STANDARD MEDICAL CARE BASED ON THE PHYSICIAN'S ADVICE. THE DURATION WAS THE SAME, I.E., 3 MONTHS. THE HEART RATE VARIABILITY AND RATE OF RESPIRATION WERE ASSESSED AT BASELINE AND AT THE END OF 3 MONTHS. RESULTS: THERE WAS A SIGNIFICANT DIFFERENCE IN THE BASELINE (PRE) VALUES BETWEEN GROUPS (P = 0.008) FOR RESPIRATION RATE WHICH WAS HIGHER IN THE YOGA GROUP. THE CHANGES REPORTED BELOW ARE PRE-POST COMPARISONS WITHIN EACH GROUP. THE YOGA GROUP SHOWED A SIGNIFICANT (P < 0.05; REPEATED MEASURES ANOVA, POST-HOC ANALYSES) DECREASE IN THE LF POWER OF HRV, RATE OF RESPIRATION AND A SIGNIFICANT INCREASE IN THE HF POWER OF HRV AND IN THE PNN50. CONCLUSION: THE RESULTS SUGGEST THAT YOGA PRACTICE CAN SHIFT THE AUTONOMIC BALANCE TOWARDS VAGAL DOMINANCE IN PATIENTS WITH CHRONIC LOW BACK PAIN ASSOCIATED WITH ALTERED ALIGNMENT OF INTERVERTEBRAL DISCS. TRIAL REGISTRATION: THE STUDY IS REGISTERED WITH THE CLINICAL TRIALS REGISTRY OF INDIA ( CTRI/2012/11/003094 ) AND CAN BE ACCESSED AT.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
14  389  34 BENEFITS OF YOGA FOR AFRICAN AMERICAN HEART FAILURE PATIENTS. BACKGROUND: THE NUMBER OF AFRICAN AMERICAN (AA) PATIENTS LIVING WITH HEART FAILURE (HF) HAS BEEN INCREASING, ESPECIALLY AMONG THE ECONOMICALLY DISADVANTAGED. YOGA THERAPY HAS BEEN FOUND TO IMPROVE PHYSICAL AND PSYCHOLOGICAL PARAMETERS AMONG HEALTHY INDIVIDUALS, BUT ITS EFFECT IN PATIENTS WITH HF REMAINS UNKNOWN. THE PURPOSE OF THIS STUDY WAS TO EXAMINE THE EFFECTS OF YOGA THERAPY ON CARDIOVASCULAR ENDURANCE (VO2PEAK), FLEXIBILITY, QUALITY OF LIFE (QOL), AND INFLAMMATORY MARKERS ON MEDICALLY STABLE HF PATIENTS. METHODS: FORTY PATIENTS (38 AA, 1 ASIAN, AND 1 CAUCASIAN) WITH SYSTOLIC OR DIASTOLIC HF WERE RANDOMIZED TO THE YOGA GROUP (YG, N = 21) OR THE CONTROL GROUP (CG, N = 19). ALL PATIENTS WERE ASKED TO FOLLOW A HOME WALK PROGRAM. PREMEASUREMENT AND POSTMEASUREMENT INCLUDED A TREADMILL STRESS TEST TO PEAK EXERTION, FLEXIBILITY, INTERLEUKIN-6 (IL-6), C-REACTIVE PROTEIN (CRP), AND EXTRACELLULAR SUPEROXIDE DISMUTASE (EC-SOD). QOL WAS ASSESSED BY THE MINNESOTA LIVING WITH HEART FAILURE QUESTIONNAIRE (MLWHFQ). RESULTS: THE STATISTICAL ANALYSES (ASSESSED BY ANOVA AND T-TESTS) WERE SIGNIFICANT FOR FAVORABLE CHANGES IN THE YG, COMPARED WITH THOSE IN THE CG, FOR FLEXIBILITY (P = 0.012), TREADMILL TIME (P = 0.002), VO2PEAK (P = 0.003), AND THE BIOMARKERS (IL-6, P = 0.004; CRP, P = 0.016; AND EC-SOD, P = 0.012). WITHIN THE YG, PRETEST TO POSTTEST SCORES FOR THE TOTAL (P = 0.02) AND PHYSICAL SUBSCALES (P < 0.001) OF THE MLWHFQ WERE IMPROVED. CONCLUSIONS: YOGA THERAPY OFFERED ADDITIONAL BENEFITS TO THE STANDARD MEDICAL CARE OF PREDOMINANTLY AA HF PATIENTS BY IMPROVING CARDIOVASCULAR ENDURANCE, QOL, INFLAMMATORY MARKERS, AND FLEXIBILITY.	2010	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
15  452  43 CHANGES IN HEART RATE VARIABILITY AFTER YOGA ARE DEPENDENT ON HEART RATE VARIABILITY AT BASELINE AND DURING YOGA: A STUDY SHOWING AUTONOMIC NORMALIZATION EFFECT IN YOGA-NAIVE AND EXPERIENCED SUBJECTS. BACKGROUND: YOGA THERAPY IS WIDELY APPLIED TO THE MAINTENANCE OF HEALTH AND TO TREATMENT OF VARIOUS ILLNESSES. PREVIOUS RESEARCHES INDICATE THE INVOLVEMENT OF AUTONOMIC CONTROL IN ITS EFFECTS, ALTHOUGH THE GENERAL AGREEMENT HAS NOT BEEN REACHED REGARDING THE ACUTE MODULATION OF AUTONOMIC FUNCTION. AIM: THE PRESENT STUDY AIMED AT REVEALING THE ACUTE EFFECT OF YOGA ON THE AUTONOMIC ACTIVITY USING HEART RATE VARIABILITY (HRV) MEASUREMENT. METHODS: TWENTY-SEVEN HEALTHY CONTROLS PARTICIPATED IN THE PRESENT STUDY. FIFTEEN OF THEM (39.5 +/- 8.5 YEARS OLD) WERE NAIVE AND 12 (45.1 +/- 7.0 YEARS OLD) WERE EXPERIENCED IN YOGA. YOGA SKILLS INCLUDED BREATH AWARENESS, TWO TYPES OF ASANA, AND TWO TYPES OF PRANAYAMA. HRV WAS MEASURED AT THE BASELINE, DURING YOGA, AND AT THE RESTING STATE AFTER YOGA. RESULTS: IN BOTH YOGA-NAIVE AND EXPERIENCED PARTICIPANTS, THE CHANGES IN LOW-FREQUENCY (LF) COMPONENT OF HRV AND ITS RATIO TO HIGH-FREQUENCY (HF) COMPONENT (LF/HF) AFTER YOGA WERE FOUND TO BE CORRELATED NEGATIVELY WITH THE BASELINE DATA. THE CHANGES IN LF AFTER YOGA WERE ALSO CORRELATED WITH LF DURING YOGA. THE CHANGES IN HF AS WELL AS THE RAW HRV DATA AFTER YOGA WERE NOT RELATED TO THE BASELINE HRV OR THE HRV DURING YOGA. CONCLUSION: THE RESULTS INDICATE THAT YOGA LEADS TO AN INCREASE IN LF WHEN LF IS LOW AND LEADS TO A DECREASE IN LF WHEN IT IS HIGH AT THE BASELINE. THIS NORMALIZATION OF LF IS DEPENDENT ON THE AUTONOMIC MODULATION DURING YOGA AND MAY UNDERLIE THE CLINICAL EFFECTIVENESS OF YOGA THERAPY BOTH IN YOGA-NAIVE AND EXPERIENCED SUBJECTS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
16  758  40 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
17  871  43 EFFECT OF YOGA THERAPY ON DISEASE ACTIVITY, INFLAMMATORY MARKERS, AND HEART RATE VARIABILITY IN PATIENTS WITH RHEUMATOID ARTHRITIS. BACKGROUND: RHEUMATOID ARTHRITIS (RA) IS AN IMMUNE-MEDIATED INFLAMMATORY DISEASE. ANTIRHEUMATOID TREATMENT REDUCES DISEASE ACTIVITY AND INFLAMMATION, BUT NOT ALL PATIENTS RESPOND TO TREATMENT. AUTONOMIC DYSFUNCTION IS COMMON IN RA LEADING TO FREQUENT CARDIOVASCULAR COMPLICATIONS. YOGA THERAPY MAY BE USEFUL IN THESE PATIENTS, BUT THERE ARE LITTLE DATA ON THE EFFECT OF YOGA ON DISEASE ACTIVITY, INFLAMMATORY MARKERS, AND HEART RATE VARIABILITY (HRV). OBJECTIVES: THIS STUDY ASSESSED THE EFFECT OF 12-WEEK YOGA THERAPY ON DISEASE ACTIVITY, INFLAMMATORY MARKERS, AND HRV IN PATIENTS WITH RA. MATERIALS AND METHODS: THIS RANDOMIZED CONTROL TRIAL WAS CONDUCTED ON NEWLY DIAGNOSED RA PATIENTS ATTENDING OUTPATIENT SERVICES AT THE DEPARTMENT OF CLINICAL IMMUNOLOGY, JIPMER. ONE HUNDRED AND SIXTY-SIX PARTICIPANTS WERE RANDOMIZED INTO TWO GROUPS: THE CONTROL GROUP (CG) (N = 83) AND YOGA GROUP (YG) (N = 83). YOGA THERAPY WAS ADMINISTERED TO PARTICIPANTS IN THE YG FOR 12 WEEKS, ALONG WITH STANDARD MEDICAL TREATMENT. THE CG RECEIVED ONLY STANDARD MEDICAL TREATMENT. PRIMARY OUTCOMES WERE DISEASE ACTIVITY SCORE 28, INTERLEUKIN-1ALPHA (IL-1ALPHA), IL-6, TUMOR NECROSIS FACTOR-ALPHA (TNF-ALPHA), CORTISOL, AND HRV PARAMETERS. ALL PARAMETERS WERE MEASURED AT BASELINE AND AFTER 12 WEEKS. RESULTS: DISEASE ACTIVITY SIGNIFICANTLY DECREASED IN BOTH GROUPS AFTER 12 WEEKS, BUT IT WAS REDUCED MORE IN YG, WHICH WAS STATISTICALLY SIGNIFICANT (P < 0.05). IN BOTH YG AND CG, IL-1ALPHA, IL-6, TNF-ALPHA, AND CORTISOL DECREASED AFTER 12 WEEKS, BUT IL-1ALPHA AND CORTISOL DECREASED MORE SIGNIFICANTLY IN YG THAN IN CG. LOW-FREQUENCY COMPONENT EXPRESSED AS NORMALIZED UNIT (LFNU) AND THE LOW-FREQUENCY/HIGH-FREQUENCY (LF-HF) RATIO DECREASED SIGNIFICANTLY, AND TOTAL POWER AND HF COMPONENT EXPRESSED AS NORMALIZED UNIT (HFNU) INCREASED SIGNIFICANTLY IN THE YG COMPARED WITH CG. CONCLUSION: TWELVE-WEEK YOGA THERAPY, IF GIVEN ALONG WITH STANDARD MEDICAL TREATMENT, SIGNIFICANTLY REDUCES DISEASE ACTIVITY AND IMPROVES SYMPATHOVAGAL BALANCE IN RA PATIENTS.	2020	
                                                                                                                  
18  812  33 EFFECT OF YOGA ON CARDIAC AUTONOMIC DYSFUNCTION AND INSULIN RESISTANCE IN NON-DIABETIC OFFSPRING OF TYPE-2-DIABETES PARENTS: A RANDOMIZED CONTROLLED STUDY. OBJECTIVE: THE PRESENT STUDY WAS AIMED TO DETERMINE THE EFFECT OF YOGA PROGRAM ON CARDIAC AUTONOMIC DYSFUNCTION AND INSULIN RESISTANCE IN NON-DIABETIC OFFSPRING OF DIABETES PARENTS. METHODS: A RANDOMIZED PASSIVE-CONTROLLED STUDY WAS CONDUCTED ON 64 NON-DIABETIC OFFSPRING OF TYPE-2-DIABETES PARENTS (MEAN-AGE:25.17YEARS). YOGA GROUP PARTICIPANTS RECEIVED YOGA TRAINING FOR 8 WEEKS. HEART-RATE VARIABILITY (HRV) INDICES: LOW FREQUENCY (LF), HIGH FREQUENCY (HF) AND LF/HF RATIO; FASTING BLOOD GLUCOSE (FBG), ORAL GLUCOSE TOLERANCE TEST (OGTT) AND INSULIN RESISTANCE (IR) WERE ESTIMATED AT BASELINE AND AFTER 8-WEEKS OF INTERVENTION. RESULTS: WE FOUND A SIGNIFICANT DECREASE IN LF (P=0.005), LF/HF RATIO (P=0.004), IR (P<0.001), OGTT (P=0.003) AND INCREASE IN HF (P=0.022) IN YOGA GROUP PARTICIPANTS. CONTROL GROUP PARTICIPANTS DID NOT SHOW ANY SIGNIFICANT CHANGE IN ANY VARIABLES. CONCLUSIONS: IMPROVEMENT IN CARDIAC AUTONOMIC FUNCTION AND INSULIN RESISTANCE BY YOGA TRAINING IMPLIES THAT YOGA CAN REDUCE THE RISK OF DEVELOPMENT OF DIABETES IN OFFSPRING OF DIABETES PARENTS.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
19 2692  25 YOGA INCREASED SERUM ESTROGEN LEVELS IN POSTMENOPAUSAL WOMEN-A CASE REPORT. OBJECTIVE: THIS CASE REPORT AIMED TO EVALUATE 4 MONTHS OF YOGA PRACTICE ON THE QUALITY OF LIFE (QOL) AND ESTRADIOL LEVELS OF TWO POSTMENOPAUSAL WOMEN. METHODS: PARTICIPANTS WERE CLINICALLY HEALTHY POSTMENOPAUSAL WOMEN, WITH FOLLICLE-STIMULATING HORMONE LEVELS GREATER THAN OR EQUAL TO 30 MIU/ML AND A BODY MASS INDEX LOWER THAN 30 KG/M. THE PARTICIPANTS PRACTICED YOGA FOR 4 MONTHS IN TWO 1-HOUR SESSIONS PER WEEK. RESULTS: THE PARTICIPANTS EXHIBITED AN ABNORMAL ESTROGEN-LEVEL INCREASE AFTER 4 MONTHS OF YOGA PRACTICE AND SHOWED QOL IMPROVEMENTS.

20  807  29 EFFECT OF YOGA ON ARRHYTHMIA BURDEN, ANXIETY, DEPRESSION, AND QUALITY OF LIFE IN PAROXYSMAL ATRIAL FIBRILLATION: THE YOGA MY HEART STUDY. OBJECTIVES: THE PURPOSE OF THIS STUDY WAS TO EXAMINE THE IMPACT OF YOGA ON ATRIAL FIBRILLATION (AF) BURDEN, QUALITY OF LIFE (QOL), DEPRESSION, AND ANXIETY SCORES. BACKGROUND: YOGA IS KNOWN TO HAVE SIGNIFICANT BENEFIT ON CARDIOVASCULAR HEALTH. THE EFFECT OF YOGA IN REDUCING AF BURDEN IS UNKNOWN. METHODS: THIS SINGLE-CENTER, PRE-POST STUDY ENROLLED PATIENTS WITH SYMPTOMATIC PAROXYSMAL AF WITH AN INITIAL 3-MONTH NONINTERVENTIONAL OBSERVATION PERIOD FOLLOWED BY TWICE-WEEKLY 60-MIN YOGA TRAINING FOR NEXT 3 MONTHS. AF EPISODES DURING THE CONTROL AND STUDY PERIODS AS WELL AS SF-36, ZUNG SELF-RATED ANXIETY, AND ZUNG SELF-RATED DEPRESSION SCORES AT BASELINE, BEFORE, AND AFTER THE STUDY PHASE WERE ASSESSED. RESULTS: YOGA TRAINING REDUCED SYMPTOMATIC AF EPISODES (3.8 +/- 3 VS. 2.1 +/- 2.6, P < 0.001), SYMPTOMATIC NON-AF EPISODES (2.9 +/- 3.4 VS. 1.4 +/- 2.0; P < 0.001), ASYMPTOMATIC AF EPISODES (0.12 +/- 0.44 VS. 0.04 +/- 0.20; P < 0.001), AND DEPRESSION AND ANXIETY (P < 0.001), AND IMPROVED THE QOL PARAMETERS OF PHYSICAL FUNCTIONING, GENERAL HEALTH, VITALITY, SOCIAL FUNCTIONING, AND MENTAL HEALTH DOMAINS ON SF-36 (P = 0.017, P < 0.001, P < 0.001, P = 0.019, AND P < 0.001, RESPECTIVELY). THERE WAS SIGNIFICANT DECREASE IN HEART RATE, AND SYSTOLIC AND DIASTOLIC BLOOD PRESSURE BEFORE AND AFTER YOGA (P < 0.001). CONCLUSIONS: IN PATIENTS WITH PAROXYSMAL AF, YOGA IMPROVES SYMPTOMS, ARRHYTHMIA BURDEN, HEART RATE, BLOOD PRESSURE, ANXIETY AND DEPRESSION SCORES, AND SEVERAL DOMAINS OF QOL.	2013
