1  419 213 BREATHING-FOCUSED YOGA INTERVENTION ON RESPIRATORY DECLINE IN CHRONICALLY PESTICIDE-EXPOSED FARMERS: A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: OCCUPATIONAL EXPOSURE TO PESTICIDES HAS BEEN ASSOCIATED WITH LUNG AND COGNITIVE FUNCTION EXACERBATIONS. IN THE PRESENT STUDY, WE TESTED THE EFFECTIVENESS OF BREATHING FOCUSED YOGA INTERVENTION ON ALLEVIATION OF ADVERSE RESPIRATORY AND COGNITIVE EFFECTS ASSOCIATED WITH CHRONIC PESTICIDE EXPOSURE IN FARMERS. METHODS: WE UNDERTOOK A PARALLEL, TWO-ARMED RANDOMIZED CONTROLLED TRIAL WITH BLINDED OUTCOME ASSESSORS ON A CHRONICALLY PESTICIDE-EXPOSED FARMING POPULATION. THE STUDY WAS CONDUCTED AT DISTRICT PANIPAT, STATE HARYANA LOCATED IN THE NORTHERN PART OF INDIA FROM NOVEMBER 2019 TO AUGUST 2020. A TOTAL OF 634 FARMERS WERE SCREENED, AND 140 FARMERS WERE RANDOMIZED TO BREATHING-FOCUSED YOGA INTERVENTION (BFY, N = 70) AND WAITLIST CONTROL ARMS (N = 65). BFY WAS DELIVERED WEEKLY IN 45-MIN GROUP SESSIONS OVER 12 WEEKS FOLLOWED BY HOME-BASED PRACTICE. THE PRIMARY OUTCOME WAS THE CHANGE IN SPIROMETRY-BASED MARKERS OF PULMONARY FUNCTION FROM BASELINE EXPRESSED AS RAW VALUES, GLOBAL LUNG INITIATIVE (GLI) PERCENT PREDICTED (PP), AND GLI Z-SCORES AFTER 24 WEEKS OF INTERVENTION. SECONDARY VARIABLES WERE TRAIL MAKING TESTS (TMT A AND B), DIGIT SYMBOL SUBSTITUTION (DSST), AND WHO QUALITY OF LIFE-BREF (WHOQOL-BREF). ANALYSIS WAS BY INTENTION-TO-TREAT. MEDIATION ANALYSIS WAS DONE CONSIDERING OXIDATIVE STRESS MARKERS AS POTENTIAL MEDIATORS. RESULTS: AT THE END OF 6 MONTHS OF INTERVENTION, THE OVERALL FOLLOW-UP IN THE PARTICIPANTS WAS 87.85% (N = 123); 90% (N = 63) IN THE CONTROL GROUP, AND 85.71% IN THE YOGA GROUP (N = 60). THE MEAN AGE OF THE STUDY COHORT (N = 140) WAS 38.75 (SD = 7.50) YEARS. COMPARED WITH THE CONTROL GROUP, AT 24 WEEKS POST-INTERVENTION, THE BFY GROUP HAD SIGNIFICANTLY IMPROVED STATUS OF THE RAW SAND Z SCORES MARKERS OF AIRWAY OBSTRUCTION, AFTER ADJUSTING FOR CONFOUNDERS, FEV1, FVC, FEF25-75 [Z SCORE-ADJUSTED MEAN DIFFERENCES (95% CI); 1.66 (1.10-2.21) 1.88 (1.21-2.55), AND 6.85 (5.12-8.57), RESPECTIVELY. A FRACTION OF FEF25-75 CHANGE (MEDIATION PERCENTAGE 23.95%) WAS EXPLAINED BY GLUTATHIONE AUGMENTATION. THERE WERE ALSO SIGNIFICANT IMPROVEMENTS IN COGNITIVE SCORES OF DSST, TMT-A AND TMT-B, AND WHOQOL-BREF. CONCLUSION: IN CONCLUSION, REGULAR PRACTICE OF BFY COULD IMPROVE THE EXACERBATIONS IN THE MARKERS OF AIRWAY OBSTRUCTION IN CHRONICALLY PESTICIDE-EXPOSED FARMERS AND COGNITIVE VARIABLES. A SIGNIFICANT MEDIATING EFFECT OF GLUTATHIONE AUGMENTATION WAS ALSO OBSERVED CONCERNING THE EFFECT OF THE INTERVENTION ON FEF25-75. THESE FINDINGS PROVIDE AN IMPORTANT PIECE OF BENEFICIAL EVIDENCE OF THE BREATHING-BASED YOGA INTERVENTION THAT NEEDS VALIDATION ACROSS DIFFERENT FARMING ETHNICITIES.CLINICAL TRIAL REGISTRATION:WWW.CLINICALTRIALS.GOV, IDENTIFIER: CTRI/2019/11/021989.	2022	

2 1578  38 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
3  350  39 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
4 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
5 2731  36 YOGA OFFERS CARDIOVASCULAR PROTECTION IN EARLY POSTMENOPAUSAL WOMEN. CONTEXT: POSTMENOPAUSE, AN ESTROGEN DEFICIENT STATE COMES WITH INCREASED INCIDENCE OF CARDIOVASCULAR DISEASES (CVDS). 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
6  866  46 EFFECT OF YOGA PROGRAM ON EXECUTIVE FUNCTIONS OF ADOLESCENTS DWELLING IN AN ORPHAN HOME: A RANDOMIZED CONTROLLED STUDY. EXECUTIVE FUNCTION (EF) IS IMPORTANT FOR PHYSICAL AND MENTAL HEALTH OF CHILDREN. STUDIES HAVE SHOWN THAT CHILDREN WITH POVERTY AND EARLY LIFE STRESS HAVE REDUCED EF. THE AIM OF THE STUDY WAS TO EVALUATE THE EFFECT OF YOGA PROGRAM ON THE EF OF ORPHAN ADOLESCENTS. SEVENTY TWO APPARENTLY HEALTHY ORPHAN ADOLESCENTS RANDOMIZED AND ALLOCATED INTO TWO GROUPS AS YOGA GROUP (N = 40; 14 GIRLS, AGE = 12.69 +/- 1.35 YRS) AND WAIT LIST CONTROL (WLC) GROUP (N = 32, 13 GIRLS, AGE = 12.58 +/- 1.52 YRS). YOGA GROUP UNDERWENT THREE MONTHS OF YOGA PROGRAM IN A SCHEDULE OF 90 MIN PER DAY, FOUR DAYS PER WEEK WHEREAS THE WLC GROUP FOLLOWED THE ROUTINE ACTIVITIES. THEY WERE ASSESSED BY STROOP COLOR-WORD TASK, DIGIT SYMBOL SUBSTITUTION TEST (DSST), DIGITS SPAN TEST AND TRIAL MAKING TEST (TMT) AT THE BEGINNING AND END OF THE PROGRAM. THE REPEATED MEASURES ANOVA SHOWED SIGNIFICANT DIFFERENCE IN TIME AND GROUP INTERACTIONS (P < 0.05) FOR ALL SUBTESTS OF STROOP COLOR-WORD TASK AND DIGIT SPAN TEST AND PART-A OF TMT WHEREAS THERE WERE NO SIGNIFICANT DIFFERENCE FOUND IN DSST AND TMT (PART-B). THE POST-HOC TEST WITH BONFERRONI ADJUSTMENT ALSO SHOWED SIGNIFICANT IMPROVEMENTS (P < 0.001) WITHIN THE YOGA GROUP IN ALL TEST SCORES WHILE IN WRONG SCORE OF DSST DID NOT EXHIBIT SIGNIFICANT REDUCTION. WHEREAS THE WLC GROUP, SHOWED SIGNIFICANT IMPROVEMENT (P < 0.05) IN STROOP COLOR, COLOR-WORD SCORE, NET SCORE OF DSST, DIGIT SPAN FORWARD AND DIGIT SPAN TOTAL.

7  370  38 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  780  45 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
9  867  47 EFFECT OF YOGA REGIMEN ON LUNG FUNCTIONS INCLUDING DIFFUSION CAPACITY IN CORONARY ARTERY DISEASE PATIENTS: A RANDOMIZED CONTROLLED STUDY. BACKGROUND: LUNG FUNCTIONS ARE FOUND TO BE IMPAIRED IN CORONARY ARTERY DISEASE (CAD), CONGESTIVE HEART FAILURE, LEFT VENTRICULAR DYSFUNCTION, AND AFTER CARDIAC SURGERY. DIFFUSION CAPACITY PROGRESSIVELY WORSENS AS THE SEVERITY OF CAD INCREASES DUE TO REDUCTION IN LUNG TISSUE PARTICIPATING IN GAS EXCHANGE. AIMS AND OBJECTIVES: PRANAYAMA BREATHING EXERCISES AND YOGIC POSTURES MAY PLAY AN IMPRESSIVE ROLE IN IMPROVING CARDIO-RESPIRATORY EFFICIENCY AND FACILITATING GAS DIFFUSION AT THE ALVEOLO-CAPILLARY MEMBRANE. THIS STUDY WAS DONE TO SEE THE EFFECT OF YOGA REGIMEN ON LUNG FUNCTIONS PARTICULARLY DIFFUSION CAPACITY IN CAD PATIENTS. MATERIALS AND METHODS: A TOTAL OF 80 STABLE CAD PATIENTS BELOW 65 YEARS OF AGE OF BOTH SEXES WERE SELECTED AND RANDOMIZED INTO TWO GROUPS OF 40 EACH. GROUP I CAD PATIENTS WERE GIVEN YOGA REGIMEN FOR 3 MONTHS WHICH CONSISTED OF YOGIC POSTURES, PRANAYAMA BREATHING EXERCISES, DIETARY MODIFICATION, AND HOLISTIC TEACHING ALONG WITH THEIR CONVENTIONAL MEDICINE WHILE GROUP II CAD PATIENTS WERE PUT ONLY ON CONVENTIONAL MEDICINE. LUNG FUNCTIONS INCLUDING DIFFUSION CAPACITY WERE RECORDED THRICE IN BOTH THE GROUPS: 0 DAY AS BASELINE, 22(ND) DAY AND ON 90(TH) DAY BY USING COMPUTERIZED MS MEDISOFT CARDIO-RESPIRATORY INSTRUMENT, HYP'AIR COMPACT MODEL OF CARDIO-RESPIRATORY TESTING MACHINE WAS MANUFACTURED BY P K MORGAN, INDIA. THE RECORDED PARAMETERS WERE STATISTICALLY ANALYZED BY REPEATED MEASURES ANOVA FOLLOWED BY TUKEY'S TEST IN BOTH THE GROUPS. CARDIOVASCULAR PARAMETERS WERE ALSO COMPARED BEFORE AND AFTER INTERVENTION IN BOTH THE GROUPS. RESULTS: STATISTICALLY SIGNIFICANT IMPROVEMENTS WERE SEEN IN SLOW VITAL CAPACITY, FORCED VITAL CAPACITY, PEAK EXPIRATORY FLOW RATE, MAXIMUM VOLUNTARY VENTILATION, AND DIFFUSION FACTOR/ TRANSFER FACTOR OF LUNG FOR CARBON MONOXIDE AFTER 3 MONTHS OF YOGA REGIMEN IN GROUP I. FORCED EXPIRATORY VOLUME IN 1(ST) SEC (FEV1), AND FEV1 % ALSO SHOWED A TREND TOWARD IMPROVEMENT ALTHOUGH NOT STATISTICALLY SIGNIFICANT. HR, SBP AND DBP ALSO SHOWED SIGNIFICANT IMPROVEMENT IN GROUP-I PATIENTS WHO FOLLOWED YOGA REGIMEN. CONCLUSIONS: YOGA REGIMEN WAS FOUND TO IMPROVE LUNG FUNCTIONS AND DIFFUSION CAPACITY IN CAD PATIENTS BESIDES IMPROVING CARDIOVASCULAR FUNCTIONS. THUS, IT CAN BE USED AS A COMPLIMENTARY OR ADJUNCT THERAPY ALONG WITH THE CONVENTIONAL MEDICINE FOR THEIR TREATMENT AND REHABILITATION.	2015	
                                                                                                                                                                                                                                                                                                                                                                    
10  214  36 A STUDY OF THE EFFECT OF YOGA TRAINING ON PULMONARY FUNCTIONS IN PATIENTS WITH BRONCHIAL ASTHMA. THE ROLE OF YOGA BREATHING EXERCISES, AS AN ADJUNCT TREATMENT FOR BRONCHIAL ASTHMA IS WELL RECOGNIZED. ONE HUNDRED TWENTY PATIENTS OF ASTHMA WERE RANDOMIZED INTO TWO GROUPS I.E GROUP A (YOGA TRAINING GROUP) AND GROUP B (CONTROL GROUP). EACH GROUP INCLUDED SIXTY PATIENTS. PULMONARY FUNCTION TESTS WERE PERFORMED ON ALL THE PATIENTS AT BASELINE, AFTER 4 WEEKS AND THEN AFTER 8 WEEKS. MAJORITY OF THE SUBJECTS IN THE TWO GROUPS HAD MILD DISEASE (34 PATIENTS IN GROUP A AND 32 IN GROUP B). GROUP A SUBJECTS SHOWED A STATISTICALLY SIGNIFICANT INCREASING TREND (P < 0.01) IN % PREDICTED PEAK EXPIRATORY FLOW RATE (PEFR), FORCED EXPIRATORY VOLUME IN THE FIRST SECOND (FEV1), FORCED VITAL CAPACITY (FVC), FORCED MID EXPIRATORY FLOW IN 0.25-0.75 SECONDS (FEF25-75) AND FEV1/FVC% RATIO AT 4 WEEKS AND 8 WEEKS AS COMPARED TO GROUP B. THUS, YOGA BREATHING EXERCISES USED ADJUNCTIVELY WITH STANDARD PHARMACOLOGICAL TREATMENT SIGNIFICANTLY IMPROVES PULMONARY FUNCTIONS IN PATIENTS WITH BRONCHIAL ASTHMA.	2009	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
11  758  36 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
12  625  49 DIABETIC YOGA PROTOCOL IMPROVES GLYCEMIC, ANTHROPOMETRIC AND LIPID LEVELS IN HIGH RISK INDIVIDUALS FOR DIABETES: A RANDOMIZED CONTROLLED TRIAL FROM NORTHERN INDIA. PURPOSE: TO STUDY THE EFFECTIVENESS OF DIABETIC YOGA PROTOCOL (DYP) AGAINST MANAGEMENT OF CARDIOVASCULAR RISK PROFILE IN A HIGH-RISK COMMUNITY FOR DIABETES, FROM CHANDIGARH, INDIA. METHODS: THE STUDY WAS A RANDOMIZED CONTROLLED TRIAL, CONDUCTED AS A SUB STUDY OF THE PAN INDIA TRIAL NIYANTRITA MADHUMEHA BHARATH (NMB). THE COHORT WAS IDENTIFIED THROUGH THE INDIAN DIABETES RISK SCORING (IDRS) (>/= 60) AND A TOTAL OF 184 INDIVIDUALS WERE RANDOMIZED INTO INTERVENTION (N = 91) AND CONTROL GROUPS (N = 93). THE DYP GROUP UNDERWENT THE SPECIFIC DYP TRAINING WHEREAS THE CONTROL GROUP FOLLOWED THEIR DAILY REGIMEN. THE STUDY OUTCOMES INCLUDED CHANGES IN GLYCEMIC AND LIPID PROFILE. ANALYSIS WAS DONE UNDER INTENT-TO-TREAT PRINCIPLE. RESULTS: THE 3 MONTHS DYP PRACTICE SHOWED DIVERSE RESULTS SHOWING GLYCEMIC AND LIPID PROFILE OF THE HIGH RISK INDIVIDUALS. THREE MONTHS OF DYP INTERVENTION WAS FOUND TO SIGNIFICANTLY REDUCE THE LEVELS OF POST-PRANDIAL GLUCOSE LEVELS (P = 0.035) AND LDL-C LEVELS (P = 0.014) AND WAIST CIRCUMFERENCE (P = 0.001). CONCLUSION: THE FINDINGS INDICATE THAT THE DYP INTERVENTION COULD IMPROVE THE METABOLIC STATUS OF THE HIGH-DIABETES-RISK INDIVIDUALS WITH RESPECT TO THEIR GLUCOSE TOLERANCE AND LIPID LEVELS, PARTIALLY EXPLAINED BY THE REDUCTION IN ABDOMINAL OBESITY. THE STUDY HIGHLIGHTS THE POTENTIAL ROLE OF YOGA INTERVENTION IN REAL TIME IMPROVEMENT OF CARDIOVASCULAR PROFILE IN A HIGH DIABETES RISK COHORT. TRIAL REGISTRATION: CTRI, CTRI/2018/03/012804.

13 1318  44 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  452  36 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
15 1558  35 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
16  944  52 EFFECTS OF A 12-WEEK HATHA YOGA INTERVENTION ON METABOLIC RISK AND QUALITY OF LIFE IN HONG KONG CHINESE ADULTS WITH AND WITHOUT METABOLIC SYNDROME. OBJECTIVE: TO DETERMINE THE EFFICACY OF A 12-WEEK HATHA YOGA INTERVENTION TO IMPROVE METABOLIC RISK PROFILES AND HEALTH-RELATED QUALITY OF LIFE (HRQOL) IN CHINESE ADULTS WITH AND WITHOUT METABOLIC SYNDROME (METS). METHODS: WE CONDUCTED A CONTROLLED TRIAL WITHIN AN UNIVERSITY-AFFILIATED HOSPITAL. 173 CHINESE MEN AND WOMEN AGED 18 OR ABOVE WERE ASSIGNED TO EITHER THE YOGA INTERVENTION GROUP (N = 87) OR THE CONTROL GROUP (N = 86). PRIMARY OUTCOMES INCLUDED 12-WEEK CHANGE IN METABOLIC RISK FACTORS AND METS Z SCORE. SECONDARY OUTCOME WAS HRQOL (MEDICAL OUTCOMES SHORT FORM SURVEY AT 12 WEEKS). RESULTS: THE MEAN AGE OF PARTICIPANTS WAS 52.0 (SD 7.4, RANGE 31-71) YEARS. ANALYSIS INVOLVING THE ENTIRE STUDY POPULATION REVEALED THAT THE YOGA GROUP ACHIEVED GREATER DECLINE IN WAIST CIRCUMFERENCE (P<0.001), FASTING GLUCOSE (P<0.01), TRIGLYCERIDES (P<0.05), AND METS Z SCORE (P<0.01). YOGA TRAINING ALSO IMPROVED GENERAL HEALTH PERCEPTIONS (P<0.01), PHYSICAL COMPONENT SCORE (P<0.01), AND SOCIAL FUNCTIONING (P<0.01) DOMAINS SCORE OF HRQOL. HOWEVER, NO SIGNIFICANT DIFFERENCES BETWEEN GROUPS WERE OBSERVED IN THE MEAN CHANGE OF SYSTOLIC/DIASTOLIC BLOOD PRESSURES OR HIGH-DENSITY LIPID PROTEIN CHOLESTEROL (ALL P>0.05). THERE WERE NO SIGNIFICANT DIFFERENCES IN THE INTERVENTION EFFECTS ON WAIST CIRCUMFERENCE AND METS Z SCORE BETWEEN THE METS SUBGROUPS (BOTH P>0.05). CONCLUSION: A 12-WEEK HATHA YOGA INTERVENTION IMPROVES METABOLIC RISK PROFILES AND HRQOL IN CHINESE ADULTS WITH AND WITHOUT METS.

17  871  40 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  297  39 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
19 2775  48 YOGA RESPIRATORY TRAINING IMPROVES RESPIRATORY FUNCTION AND CARDIAC SYMPATHOVAGAL BALANCE IN ELDERLY SUBJECTS: A RANDOMISED CONTROLLED TRIAL. OBJECTIVES: SINCE AGEING IS ASSOCIATED WITH A DECLINE IN PULMONARY FUNCTION, HEART RATE VARIABILITY AND SPONTANEOUS BAROREFLEX, AND RECENT STUDIES SUGGEST THAT YOGA RESPIRATORY EXERCISES MAY IMPROVE RESPIRATORY AND CARDIOVASCULAR FUNCTION, WE HYPOTHESISED THAT YOGA RESPIRATORY TRAINING MAY IMPROVE RESPIRATORY FUNCTION AND CARDIAC AUTONOMIC MODULATION IN HEALTHY ELDERLY SUBJECTS. DESIGN: 76 HEALTHY ELDERLY SUBJECTS WERE ENROLLED IN A RANDOMISED CONTROL TRIAL IN BRAZIL AND 29 COMPLETED THE STUDY (AGE 68 +/- 6 YEARS, 34% MALES, BODY MASS INDEX 25 +/- 3 KG/M(2)). SUBJECTS WERE RANDOMISED INTO A 4-MONTH TRAINING PROGRAM (2 CLASSES/WEEK PLUS HOME EXERCISES) OF EITHER STRETCHING (CONTROL, N=14) OR RESPIRATORY EXERCISES (YOGA, N=15). YOGA RESPIRATORY EXERCISES (BHASTRIKA) CONSISTED OF RAPID FORCED EXPIRATIONS FOLLOWED BY INSPIRATION THROUGH THE RIGHT NOSTRIL, INSPIRATORY APNOEA WITH GENERATION OF INTRATHORACIC NEGATIVE PRESSURE, AND EXPIRATION THROUGH THE LEFT NOSTRIL. PULMONARY FUNCTION, MAXIMUM EXPIRATORY AND INSPIRATORY PRESSURES (PE(MAX) AND PI(MAX), RESPECTIVELY), HEART RATE VARIABILITY AND BLOOD PRESSURE VARIABILITY FOR SPONTANEOUS BAROREFLEX DETERMINATION WERE DETERMINED AT BASELINE AND AFTER 4 MONTHS. RESULTS: SUBJECTS IN BOTH GROUPS HAD SIMILAR DEMOGRAPHIC PARAMETERS. PHYSIOLOGICAL VARIABLES DID NOT CHANGE AFTER 4 MONTHS IN THE CONTROL GROUP. HOWEVER, IN THE YOGA GROUP, THERE WERE SIGNIFICANT INCREASES IN PE(MAX) (34%, P<0.0001) AND PI(MAX) (26%, P<0.0001) AND A SIGNIFICANT DECREASE IN THE LOW FREQUENCY COMPONENT (A MARKER OF CARDIAC SYMPATHETIC MODULATION) AND LOW FREQUENCY/HIGH FREQUENCY RATIO (MARKER OF SYMPATHOVAGAL BALANCE) OF HEART RATE VARIABILITY (40%, P<0.001). SPONTANEOUS BAROREFLEX DID NOT CHANGE, AND QUALITY OF LIFE ONLY MARGINALLY INCREASED IN THE YOGA GROUP. CONCLUSION: RESPIRATORY YOGA TRAINING MAY BE BENEFICIAL FOR THE ELDERLY HEALTHY POPULATION BY IMPROVING RESPIRATORY FUNCTION AND SYMPATHOVAGAL BALANCE.

20  674  41 EFFECT OF A SHORT-TERM YOGA-BASED LIFESTYLE INTERVENTION ON HEALTH-RELATED QUALITY OF LIFE IN OVERWEIGHT AND OBESE SUBJECTS. OBJECTIVE: TO STUDY THE EFFECT OF A SHORT-TERM YOGA-BASED LIFESTYLE INTERVENTION ON HEALTH-RELATED QUALITY OF LIFE (HRQOL) IN OVERWEIGHT AND OBESE PERSONS. DESIGN AND SETTING: NONRANDOMIZED, SINGLE-ARM INTERVENTIONAL STUDY CONDUCTED FROM AUGUST 2012 TO MARCH 2015 AT INTEGRAL HEALTH CLINIC, DEPARTMENT OF PHYSIOLOGY, ALL INDIA INSTITUTE OF MEDICAL SCIENCES, NEW DELHI, INDIA. PARTICIPANTS: OVERWEIGHT (BODY-MASS INDEX [BMI], 23-24.9 KG/M(2)) AND OBESE (BMI, >/=25 KG/M(2)) PERSONS (N = 279) AGED 20-60 YEARS. INTERVENTION: PRETESTED YOGA-BASED LIFESTYLE INTERVENTION, INCLUDING ASANAS (POSTURES), PRANAYAMA (BREATHING EXERCISES), RELAXATION TECHNIQUES, LECTURES, GROUP SUPPORT, NUTRITION AWARENESS PROGRAM, AND INDIVIDUALIZED ADVICE. OUTCOME MEASURES: PRIMARY OUTCOME MEASURE WAS HRQOL, MEASURED BY USING SHORT VERSION OF WORLD HEALTH ORGANIZATION QUALITY OF LIFE (WHOQOL-BREF) QUESTIONNAIRE. SECONDARY OUTCOME MEASURES WERE ANTHROPOMETRIC VARIABLES, SYSTOLIC AND DIASTOLIC BLOOD PRESSURE, PULSE RATE, LIPID PROFILE, AND FASTING GLUCOSE. A SUBGROUP ANALYSIS ACCORDING TO SEX WAS ALSO PERFORMED. RESULTS: THE OVERALL QUALITY OF LIFE AND HEALTH IMPROVED AFTER SHORT-TERM YOGA-BASED LIFESTYLE INTERVENTION IN OVERWEIGHT AND OBESE PERSONS. PHYSICAL, PSYCHOLOGICAL AND ENVIRONMENTAL DOMAIN SCORES SIGNIFICANTLY INCREASED FROM BASELINE TO DAY 10, AND EFFICACY WAS NOTED IN BOTH MALE AND FEMALE SUBGROUPS. AFTER 10 DAYS OF INTERVENTION, THE FOLLOWING ALSO DECREASED SIGNIFICANTLY: BODY WEIGHT, BMI, TOTAL BODY FAT, WAIST AND HIP CIRCUMFERENCE, WAIST-TO-HIP RATIO, SYSTOLIC AND DIASTOLIC BLOOD PRESSURE, TOTAL CHOLESTEROL, LOW-DENSITY LIPOPROTEIN, TRIGLYCERIDES, AND FASTING GLUCOSE. CONCLUSION: A SHORT-TERM YOGA-BASED LIFESTYLE INTERVENTION HAD A POSITIVE EFFECT ON HRQOL IN OVERWEIGHT AND OBESE PERSONS.	2016
