1 1032 155 EFFECTS OF YOGA EXERCISES ON DIABETIC MELLITUS AS VALIDATED BY MAGNETIC RESONANCE IMAGING. CONTEXT AND AIMS: EFFECTS OF PRACTICING YOGA IN DIABETIC MELLITUS (DM) PATIENTS HAVE BEEN IDENTIFIED TO IMPROVE IN CONTROL OF BLOOD GLUCOSE LEVELS. THE PURPOSE OF THIS WORK IS TO EVALUATE CHANGES IN BLOOD FLOW OF CALF MUSCLES AFTER SPECIFIC YOGA POSTURES FOR PATIENTS WITH DM USING MAGNETIC RESONANCE IMAGING (MRI) TECHNIQUES. TIME OF FLIGHT (TOF) MAGNETIC RESONANCE ANGIOGRAPHY MAXIMUM INTENSITY PROJECTION (MIP), T1 MAPS, T2 MAPS, AND DIFFUSION-WEIGHTED IMAGING ARE PERFORMED ON VOLUNTEERS AND DM PATIENTS BOTH PRE- AND POST-EXERCISE. MATERIALS AND METHODS: TOF MIP, T1 MAPS WITH VARIABLE FLIP ANGLES, AND T2-WEIGHTED SPIN-ECHO IMAGING WERE PERFORMED ON FOUR VOLUNTEERS (AGED 30 +/- 5) AND DM PATIENTS (AGED 32-68) PREEXERCISE, ON A 1.5 T SIEMENS SCANNER. THE TOTAL ACQUISITION TIME WAS 6 MIN 20 S. EACH VOLUNTEER AND DM PATIENT WERE THEN REQUESTED TO PERFORM YOGA POSTURES SUPTA PADANGUSTHASANA, UTKATASANA, AND CALF RAISE FOR 6 MIN 30 S AT MAXIMUM EFFORT, OUTSIDE THE SCANNER, AND SUBSEQUENTLY RESCANNED. TO CALCULATE SIGNIFICANT SIGNAL INCREASE, REGION OF INTERESTS WAS DRAWN ON TOF MIP CORONAL IMAGES IN ARTERIES OF CALF MUSCLES. STUDENT T-TESTS WERE PERFORMED TO DETERMINE STATISTICAL SIGNIFICANCE. RESULTS: AMONG VOLUNTEERS, A SIGNIFICANT SIGNAL INCREASE IN ARTERIES OF CALF MUSCLES WAS NOTICED, SIGNAL INTENSITY GRAPHS WERE PLOTTED. IN DM PATIENTS, SIGNAL INCREASE IN TOF MIP, T2-WEIGHTED IMAGES WERE SEEN IN SPECIFIC ARTERIES (POSTERIOR, ANTERIOR TIBIAL, AND POSTERIOR TIBIAL) OF CALF MUSCLES POSTEXERCISE. DISCUSSION AND CONCLUSIONS: THE STUDY INDICATES THAT YOGA HAS A POSITIVE SHORT-TERM EFFECT ON MULTIPLE DM-RELATED FOOT COMPLICATIONS. THIS STUDY DEPICTS THAT MRI PROVIDES POTENTIAL INSIGHT INTO THE BENEFITS OF YOGA FOR DM PATIENTS THROUGH DERIVING BIOMARKERS FOR PREVENTIVE MEDICINE RELEVANT TO YOGA INTERCEPTION.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
2  693  30 EFFECT OF CONTROLLED BREATHING EXERCISES ON THE PSYCHOLOGICAL STATUS AND THE CARDIAC AUTONOMIC TONE: SUDARSHAN KRIYA AND PRANA-YOGA. OBJECTIVE: THE OBJECTIVE OF THE STUDY WAS TO OBSERVE THE EFFECT OF CONTROLLED BREATHING EXERCISES INCLUDING SUDARSHAN KRIYA (SK) AND PRANA-YOGA (PY) ON THE PSYCHO-PHYSIOLOGICAL STATUS. METHODS: THE STUDY GROUP INCLUDED 60 HEALTHY VOLUNTEERS (M:30, F:30) IN THE AGE GROUP OF 18 TO 30 YEARS (21.3 +/- 3.2 YRS), RANDOMLY DIVIDED IN TO THREE GROUPS OF 20 SUBJECTS EACH--(1) THE SK GROUP (2) THE PY GROUP AND THE (3) CONTROL GROUP. THE PSYCHO-PHYSIOLOGICAL DATA WAS COLLECTED AT THE FOLLOWING FOUR TIME INTERVENTIONS: BASELINE, 6TH, 60TH AND THE 150TH DAY. PSYCHOLOGICAL ASSESSMENT WAS DONE USING QUESTIONNAIRES AND FOR THE AUTONOMIC TONE QUANTIFICATION HEART RATE VARIABILITY (HRV) ANALYSIS WAS DONE USING THE STANDARD LEAD II ELECTROCARDIOGRAM RECORDINGS. IN A POST-HOC ANALYSIS EACH GROUP WAS FURTHER SUB DIVIDED IN TO THE FOLLOWING TWO PATTERNS, BASED ON THE BASELINE VALUES OF NORMALIZED LOW FREQUENCY (LF) POWER (CUTOFF 64 MS2): (I) PATTERN A-SUBJECTS WITH LOW LEVEL LF POWER, AND (II) PATTERN B- SUBJECTS WITH HIGH LEVEL LF POWER. RESULTS: THE STRESS MANAGEMENT SKILLS HAVE SHOWN SIGNIFICANT INCREASE IN SK GROUP BUT NOT IN PY AND CONTROL GROUP. SUBJECTS OF SK, PY, AND CONTROL GROUP SHOWED SIGNIFICANT INCREASE IN LF VALUE AND LF:HF RATIO FOR PATTERN A AND SIGNIFICANT DECREASE FOR PATTERN B. PLOTTED LF VALUE FOR PATTERN A & B IN SK AND PY PRACTITIONERS SHOWED CONVERGENCE, COMING TO A MEAN VALUE OVER THE PERIOD OF 150 DAYS. THE LF:HF RATIO CURVE PLOTTED OVER TIME FOR PATTERN A & B SHOWED CONVERGENCE IN SK GROUP ONLY. NO SUCH CONVERGENCE IN LF VALUE & LF/HF RATIO FOR PATTERN A & B WAS SEEN IN CONTROL GROUP. CONCLUSION: IN CONCLUSION, SUDARSHAN KRIYA POSITIVELY MODIFIES STRESS COPING BEHAVIOR AND INITIATES APPROPRIATE BALANCE IN CARDIAC AUTONOMIC TONE.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
3  350  36 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 1578  36 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
5 1317  26 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
6 2731  32 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
7  448  37 CHANGES IN AUTONOMIC VARIABLES FOLLOWING TWO MEDITATIVE STATES DESCRIBED IN YOGA TEXTS. OBJECTIVES: IN ANCIENT YOGA TEXTS THERE ARE TWO MEDITATIVE STATES DESCRIBED. ONE IS DHARANA, WHICH REQUIRES FOCUSING, THE SECOND IS DHYANA, DURING WHICH THERE IS NO FOCUSING, BUT AN EXPANSIVE MENTAL STATE IS REACHED. WHILE AN EARLIER STUDY DID SHOW IMPROVED PERFORMANCE IN AN ATTENTION TASK AFTER DHARANA, THE AUTONOMIC CHANGES DURING THESE TWO STATES HAVE NOT BEEN STUDIED. METHODS: AUTONOMIC AND RESPIRATORY VARIABLES WERE ASSESSED IN 30 HEALTHY MALE VOLUNTEERS (GROUP MEAN AGE +/- SD, 29.1 +/- 5.1 YEARS) DURING FOUR MENTAL STATES DESCRIBED IN TRADITIONAL YOGA TEXTS. THESE FOUR MENTAL STATES ARE RANDOM THINKING (CANCALATA), NONMEDITATIVE FOCUSING (EKAGRATA), MEDITATIVE FOCUSING (DHARANA), AND EFFORTLESS MEDITATION (DHYANA). ASSESSMENTS WERE MADE BEFORE (5 MINUTES), DURING (20 MINUTES), AND AFTER (5 MINUTES), EACH OF THE FOUR STATES, ON FOUR SEPARATE DAYS. RESULTS: DURING DHYANA THERE WAS A SIGNIFICANT INCREASE IN THE SKIN RESISTANCE LEVEL (P<0.001; POST HOC ANALYSIS FOLLOWING ANOVA, DURING COMPARED TO PRE) AND PHOTO-PLETHYSMOGRAM AMPLITUDE (P<0.05), WHEREAS THERE WAS A SIGNIFICANT DECREASE IN THE HEART RATE (P<0.001) AND BREATH RATE (P<0.001). THERE WAS A SIGNIFICANT DECREASE IN THE LOW FREQUENCY (LF) POWER (P<0.001) AND INCREASE IN THE HIGH FREQUENCY (HF) POWER (P<0.001) IN THE FREQUENCY DOMAIN ANALYSIS OF THE HEART RATE VARIABILITY (HRV) SPECTRUM, ON WHICH HF POWER IS ASSOCIATED WITH PARASYMPATHETIC ACTIVITY. THERE WAS ALSO A SIGNIFICANT INCREASE IN THE NN50 COUNT (THE NUMBER OF INTERVAL DIFFERENCES OF SUCCESSIVE NN INTERVALS GREATER THAN 50 MS; P<0.001) AND THE PNN50 (THE PROPORTION DERIVED BY DIVIDING NN50 BY THE TOTAL NUMBER OF NN INTERVALS; P<0.001) IN TIME DOMAIN ANALYSIS OF HRV, BOTH INDICATIVE OF PARASYMPATHETIC ACTIVITY. CONCLUSIONS: MAXIMUM CHANGES WERE SEEN IN AUTONOMIC VARIABLES AND BREATH RATE DURING THE STATE OF EFFORTLESS MEDITATION (DHYANA). THE CHANGES WERE ALL SUGGESTIVE OF REDUCED SYMPATHETIC ACTIVITY AND/OR INCREASED VAGAL MODULATION. DURING DHARANA THERE WAS AN INCREASE IN SKIN RESISTANCE. THE CHANGES IN HRV DURING EKAGRATA AND CANCALATA WERE INCONCLUSIVE.	2013	
                                                                                                                                                                                                                                                                                                              
8 1441  30 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  411  33 BLOOD PRESSURE AND HEART RATE VARIABILITY DURING YOGA-BASED ALTERNATE NOSTRIL BREATHING PRACTICE AND BREATH AWARENESS. BACKGROUND: PREVIOUS RESEARCH HAS SHOWN A REDUCTION IN BLOOD PRESSURE (BP) IMMEDIATELY AFTER THE PRACTICE OF ALTERNATE NOSTRIL YOGA BREATHING (ANYB) IN NORMAL HEALTHY MALE VOLUNTEERS AND IN HYPERTENSIVE PATIENTS OF BOTH SEXES. THE BP DURING ANYB HAS NOT BEEN RECORDED. MATERIAL/METHODS: PARTICIPANTS WERE 26 MALE VOLUNTEERS (GROUP MEAN AGE +/-SD, 23.8+/-3.5 YEARS). WE ASSESSED (1) HEART RATE VARIABILITY, (2) NON-INVASIVE ARTERIAL BP, AND (3) RESPIRATION RATE, DURING (A) ANYB AND (B) BREATH AWARENESS (BAW) SESSIONS. EACH SESSION WAS 25 MINUTES. WE PERFORMED ASSESSMENTS AT 3 TIME POINTS: PRE (5 MINUTES), DURING (15 MINUTES; FOR ANYB OR BAW) AND POST (5 MINUTES). A NAIVE-TO-YOGA CONTROL GROUP (N=15 MALES, MEAN AGE +/-SD 26.1+/-4.0 YEARS) WERE ASSESSED WHILE SEATED QUIETLY FOR 25 MINUTES. RESULTS: DURING ANYB THERE WAS A SIGNIFICANT DECREASE (REPEATED MEASURES ANOVA) IN SYSTOLIC BP AND RESPIRATION RATE; WHILE RMSSD (THE SQUARE ROOT OF THE MEAN OF THE SUM OF SQUARES OF DIFFERENCES BETWEEN ADJACENT NN INTERVALS) AND NN50 (THE NUMBER OF INTERVAL DIFFERENCES OF SUCCESSIVE NORMAL TO NORMAL INTERVALS GREATER THAN 50 MS) SIGNIFICANTLY INCREASED. DURING BAW RESPIRATION RATE DECREASED. IN CONTRAST, RESPIRATION RATE INCREASED DURING THE CONTROL STATE. ANYB AND BAW WERE SIGNIFICANTLY DIFFERENT (2-FACTOR ANOVA) IN RMSSD AND RESPIRATION RATE. BAW AND CONTROL WERE DIFFERENT WITH RESPECT TO RESPIRATION RATE. CONCLUSIONS: THE RESULTS SUGGEST THAT VAGAL ACTIVITY INCREASED DURING AND AFTER ANYB, WHICH COULD HAVE CONTRIBUTED TO THE DECREASE IN BP AND CHANGES IN THE HRV.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
10  812  27 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
11  758  26 EFFECT OF SLOW BREATHING ON AUTONOMIC TONE & BAROREFLEX SENSITIVITY IN YOGA PRACTITIONERS. BACKGROUND & OBJECTIVES: SLOW BREATHING INCREASES PARASYMPATHETIC ACTIVITY AND BAROREFLEX SENSITIVITY (BRS) IN HEALTHY INDIVIDUALS, ALSO SIMILARLY OBSERVED IN YOGA PRACTITIONERS. PRANAYAMA WHICH IS AN IMPORTANT COMPONENT OF YOGA WHEN PRACTICED AT A SLOW PACE WAS AT A RESPIRATORY FREQUENCY OF AROUND 0.1 HZ (6 BREATHS/MIN). THEREFORE, IT WAS HYPOTHESIZED THAT YOGA PRACTITIONERS MIGHT HAVE ADAPTED TO SLOW BREATHING. THIS STUDY WAS AIMED TO DECIPHER THE ROLE OF YOGA ON CARDIOVASCULAR VARIABILITY DURING SLOW BREATHING (0.1 HZ) IN YOGA PRACTITIONERS. METHODS: A CROSS-SECTIONAL STUDY WAS UNDERTAKEN IN NAIVE-TO-YOGA INDIVIDUALS (N=40) AND YOGA PRACTITIONERS (N=40) WITH AN AVERAGE AGE OF 31.08 +/- 7.31 AND 29.93 +/- 7.57 YR, RESPECTIVELY. THE ANALYSIS OF HEART RATE VARIABILITY, BLOOD PRESSURE VARIABILITY (BPV) AND BRS DURING SPONTANEOUS AND SLOW BREATHING WAS COMPARED BETWEEN THE TWO GROUPS. RESULTS: DURING SLOW BREATHING, THE HEART RATE (P<0.01) WAS LOWER, RESPIRATORY RATE INTERVAL (P<0.05) AND PNN50 PER CENT (P=0.01) WERE HIGHER, MEAN SYSTOLIC BP (SBP) (P<0.05) AND SDSD (STANDARD DEVIATION OF SUCCESSIVE BEAT TO BEAT SYSTOLIC BLOOD PRESSURE DIFFERENCES) (P<0.01) OF SBP VARIABILITY WERE LOWER WITH SEQUENCE BRS (P<0.001) AND ALPHA LOW FREQUENCY (P<0.01) AND ALPHA HIGH FREQUENCY (P<0.001) OF SPECTRAL BRS WERE HIGHER IN YOGA PRACTITIONERS. INTERPRETATION & CONCLUSIONS: THE PRESENT STUDY INDICATED HIGHER PARASYMPATHETIC ACTIVITY AND BRS WITH LOWER SBP VARIABILITY AT REST AND DURING SLOW BREATHING IN YOGA PRACTITIONERS COMPARED TO NAIVE GROUP. FINDINGS INDICATE THAT THE SHORT-TERM PRACTICE OF SLOW BREATHING COMPLEMENTS THE AUGMENTED PARASYMPATHETIC ACTIVITY AND BRS IN THE YOGA GROUP.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
12  297  27 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
13 1359  32 IMMEDIATE EFFECTS OF OM CHANTING ON HEART RATE VARIABILITY MEASURES COMPARED BETWEEN EXPERIENCED AND INEXPERIENCED YOGA PRACTITIONERS. BACKGROUND: CHANTING "OM" IS A FORM OF MEDITATION THAT HAS NUMEROUS HEALTH BENEFITS. HOWEVER, THE NEUROPHYSIOLOGICAL MECHANISMS UNDERPINNING ITS EFFECT ARE SURPRISINGLY SCARCE. THE PRESENT STUDY AIMED TO INVESTIGATE THE EFFECT OF OM CHANTING ON AUTONOMIC MODULATION, USING HEART RATE VARIABILITY (HRV), ON EXPERIENCED YOGA PRACTITIONERS AND YOGA NAIVE PERSONS. METHODS: THIS PROSPECTIVE STUDY INCLUDED 19 YOGA PRACTITIONERS (9 FEMALES AND 10 MALES; GROUP MEAN AGE +/- STANDARD DEVIATION [SD]; 25.9 +/- 3.2 YEARS) AND 17 YOGA NAIVE PERSONS (8 FEMALES AND 9 MALES; GROUP MEAN AGE +/- SD; 24.8 +/- 3.6 YEARS) OF BOTH SEXES AND SIMILAR AGE RANGE. BOTH THE GROUPS WERE ASSESSED FOR HRV INDICES (TIME AND FREQUENCY DOMAIN MEASURES) BEFORE AND AFTER LOUD OM CHANTING FOR 5 MIN. RESULTS: BASELINE COMPARISON USING MANN-WHITNEY U TEST BETWEEN GROUPS SHOWED YOGA PRACTITIONERS HAD SIGNIFICANTLY INCREASED HIGH FREQUENCY (HF) POWER (P < 0.029) THAN NONYOGA PRACTITIONERS, SIGNIFYING A STATE OF TRANQUILITY BEFORE THE CHANTING OF OM. AFTER 5 MIN OF LOUD CHANTING OF OM, A COMPARISON BETWEEN GROUPS ASSESSED USING WILCOXON SIGNED RANKS TEST REVEALED: HF POWER, A COMPONENT OF THE PARASYMPATHETIC NERVOUS SYSTEM, WAS FURTHER AMPLIFIED WITH A SIGNIFICANTLY INCREASE (P < 0.001) IN THE YOGA PRACTITIONERS GROUP COMPARED TO NONYOGA PRACTITIONERS. FURTHERMORE, THIS INCREASE IN HF POWER WAS POSITIVELY CORRELATED WITH THE YEARS OF EXPERIENCE IN YOGA. CONCLUSION: THE PRESENT STUDY SHOWED THAT A BRIEF CHANTING OF OM (5 MIN) MIGHT ENHANCE PARASYMPATHETIC NERVOUS SYSTEM ACTIVITY, PROMOTE RELAXATION, AND PROVIDE CALMNESS. FURTHER, THIS EXPERIENCE MAY BE ACHIEVED EFFECTIVELY IN INDIVIDUALS EXPERIENCED IN YOGA THAN NONYOGA PRACTITIONERS.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
14  985  37 EFFECTS OF HATHA YOGA AND OMKAR MEDITATION ON CARDIORESPIRATORY PERFORMANCE, PSYCHOLOGIC PROFILE, AND MELATONIN SECRETION. OBJECTIVES: TO EVALUATE EFFECTS OF HATHA YOGA AND OMKAR MEDITATION ON CARDIORESPIRATORY PERFORMANCE, PSYCHOLOGIC PROFILE, AND MELATONIN SECRETION. SUBJECTS AND METHODS: THIRTY HEALTHY MEN IN THE AGE GROUP OF 25-35 YEARS VOLUNTEERED FOR THE STUDY. THEY WERE RANDOMLY DIVIDED IN TWO GROUPS OF 15 EACH. GROUP 1 SUBJECTS SERVED AS CONTROLS AND PERFORMED BODY FLEXIBILITY EXERCISES FOR 40 MINUTES AND SLOW RUNNING FOR 20 MINUTES DURING MORNING HOURS AND PLAYED GAMES FOR 60 MINUTES DURING EVENING HOURS DAILY FOR 3 MONTHS. GROUP 2 SUBJECTS PRACTICED SELECTED YOGIC ASANAS (POSTURES) FOR 45 MINUTES AND PRANAYAMA FOR 15 MINUTES DURING THE MORNING, WHEREAS DURING THE EVENING HOURS THESE SUBJECTS PERFORMED PREPARATORY YOGIC POSTURES FOR 15 MINUTES, PRANAYAMA FOR 15 MINUTES, AND MEDITATION FOR 30 MINUTES DAILY, FOR 3 MONTHS. ORTHOSTATIC TOLERANCE, HEART RATE, BLOOD PRESSURE, RESPIRATORY RATE, DYNAMIC LUNG FUNCTION (SUCH AS FORCED VITAL CAPACITY, FORCED EXPIRATORY VOLUME IN 1 SECOND, FORCED EXPIRATORY VOLUME PERCENTAGE, PEAK EXPIRATORY FLOW RATE, AND MAXIMUM VOLUNTARY VENTILATION), AND PSYCHOLOGIC PROFILE WERE MEASURED BEFORE AND AFTER 3 MONTHS OF YOGIC PRACTICES. SERIAL BLOOD SAMPLES WERE DRAWN AT VARIOUS TIME INTERVALS TO STUDY EFFECTS OF THESE YOGIC PRACTICES AND OMKAR MEDITATION ON MELATONIN LEVELS. RESULTS: YOGIC PRACTICES FOR 3 MONTHS RESULTED IN AN IMPROVEMENT IN CARDIORESPIRATORY PERFORMANCE AND PSYCHOLOGIC PROFILE. THE PLASMA MELATONIN ALSO SHOWED AN INCREASE AFTER THREE MONTHS OF YOGIC PRACTICES. THE SYSTOLIC BLOOD PRESSURE, DIASTOLIC BLOOD PRESSURE, MEAN ARTERIAL PRESSURE, AND ORTHOSTATIC TOLERANCE DID NOT SHOW ANY SIGNIFICANT CORRELATION WITH PLASMA MELATONIN. HOWEVER, THE MAXIMUM NIGHT TIME MELATONIN LEVELS IN YOGA GROUP SHOWED A SIGNIFICANT CORRELATION (R = 0.71, P < 0.05) WITH WELL-BEING SCORE. CONCLUSION: THESE OBSERVATIONS SUGGEST THAT YOGIC PRACTICES CAN BE USED AS PSYCHOPHYSIOLOGIC STIMULI TO INCREASE ENDOGENOUS SECRETION OF MELATONIN, WHICH, IN TURN, MIGHT BE RESPONSIBLE FOR IMPROVED SENSE OF WELL-BEING.	2004	
                                                                                                                                                                                                                                                                                                                                                
15 1329  33 HIGH-FREQUENCY CEREBRAL ACTIVATION AND INTERHEMISPHERIC SYNCHRONIZATION FOLLOWING SUDARSHAN KRIYA YOGA AS GLOBAL BRAIN RHYTHMS: THE STATE EFFECTS. CONTEXT: RESPIRATION IS KNOWN TO MODULATE NEURONAL OSCILLATIONS IN THE BRAIN AND IS MEASURED BY ELECTROENCEPHALOGRAM (EEG). SUDARSHAN KRIYA YOGA (SKY) IS A POPULAR BREATHING PROCESS AND IS ESTABLISHED FOR ITS SIGNIFICANT EFFECTS ON THE VARIOUS ASPECTS OF PHYSIOLOGY AND PSYCHOLOGY. AIMS: THIS STUDY AIMED TO OBSERVE NEURONAL OSCILLATIONS IN MULTIFREQUENCY BANDS AND INTERHEMISPHERIC SYNCHRONIZATION FOLLOWING SKY. SETTINGS AND DESIGN: THIS STUDY EMPLOYED BEFORE- AND AFTER-STUDY DESIGN. SUBJECTS AND METHODS: FORTY HEALTHY VOLUNTEERS (AVERAGE AGE 25.45 +/- 5.75, 23 MALES AND 17 FEMALES) PARTICIPATED IN THE STUDY. NINETEEN-CHANNEL EEG WAS RECORDED AND ANALYZED FOR 5 MIN EACH: BEFORE AND AFTER SKY. SPECTRAL POWER FOR DELTA, THETA, ALPHA, BETA, AND GAMMA FREQUENCY BAND WAS CALCULATED USING MULTI-TAPER FAST FOURIER TRANSFORM (CHRONUX TOOLBOX). THE ASYMMETRY INDEX WAS CALCULATED BY SUBTRACTING THE NATURAL LOG OF POWERS OF LEFT (L) HEMISPHERE FROM THE RIGHT((R)) TO SHOW INTERHEMISPHERIC SYNCHRONIZATION. STATISTICAL ANALYSIS: PAIRED T-TEST WAS USED FOR STATISTICAL ANALYSIS. RESULTS: SPECTRAL POWER INCREASED SIGNIFICANTLY IN ALL FREQUENCY BANDS BILATERALLY IN FRONTAL, CENTRAL, PARIETAL, TEMPORAL, AND OCCIPITAL REGIONS OF THE BRAIN AFTER LONG SKY. ELECTRICAL ACTIVITY SHIFTED FROM LOWER TO HIGHER FREQUENCY RANGE WITH A SIGNIFICANT RISE IN THE GAMMA AND BETA POWERS FOLLOWING SKY. ASYMMETRY INDEX VALUES TENDED TOWARD 0 FOLLOWING SKY. CONCLUSIONS: A SINGLE SESSION OF SKY GENERATES GLOBAL BRAIN RHYTHM DOMINANTLY WITH HIGH-FREQUENCY CEREBRAL ACTIVATION AND INITIATES APPROPRIATE INTERHEMISPHERIC SYNCHRONIZATION IN BRAIN RHYTHMS AS STATE EFFECTS. THIS SUGGESTS THAT SKY LEADS TO BETTER ATTENTION, MEMORY, AND EMOTIONAL AND AUTONOMIC CONTROL ALONG WITH ENHANCED COGNITIVE FUNCTIONS, WHICH FINALLY IMPROVES PHYSICAL AND MENTAL WELL-BEING.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
16  370  25 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
17  703  35 EFFECT OF INTEGRAL YOGA ON PSYCHOLOGICAL AND HEALTH VARIABLES AND THEIR CORRELATIONS. OBJECTIVE: CERTAIN PSYCHOLOGICAL AND HEALTH VARIABLES ARE COMMONLY MEASURED IN INDIA. THIS STUDY EVALUATES THE EFFECTS OF INTEGRAL YOGA PRACTICES ON THESE VARIABLES AND ALSO THE CONSISTENCY OF CORRELATIONS OBSERVED BETWEEN THEM. MATERIALS AND METHODS: THE STUDY WAS A PRE-POST INTERVENTION STUDY. THE VARIABLES WERE MEASURED AT THE BEGINNING AND THE END OF A ONE-MONTH YOGA COURSE. THERE WAS NO CONTROL GROUP.THE STUDY WAS CARRIED OUT AT SWAMI VIVEKANANDA YOGA ANUSANDHANA SAMSTHANA (S-VYASA) UNIVERSITY, IN ITS RURAL CAMPUS SOUTH OF BANGALORE. BASED ON HEALTH CRITERIA, 108 SUBJECTS WERE SELECTED OUT OF 198 VOLUNTEERS TO FORM THE EXPERIMENTAL YOGA GROUP. AGES RANGED FROM 17 TO 63 YEARS. THE YOGASANAS (POSTURES), PRANAYAMA (BREATHING EXERCISES), RELAXATION TECHNIQUES, MEDITATION, CHANTING AND LECTURES WERE THE COMPONENTS OF YOGA INTERVENTION. THE VARIABLES MEASURED WERE SUSTAINED ATTENTION, EMOTIONAL INTELLIGENCE - EQ, GENERAL HEALTH - GHQ, GUNA PERSONALITY - SATTVA, RAJAS AND TAMAS. RESULTS: SIGNIFICANT PRE-POST CHANGES WERE FOUND IN ALL VARIABLES. SIGNIFICANT CORRELATIONS WERE FOUND BETWEEN THE FOLLOWING PAIRS: THE TWO SUSTAINED ATTENTION VARIABLES; EMOTIONAL INTELLIGENCE AND GENERAL HEALTH; GHQ AND TAMAS; SATTVA AND TAMAS; AND RAJAS AND TAMAS. CONCLUSION: THE STUDY SHOWS THAT THERE WERE SIGNIFICANT CHANGES IN ALL VARIABLES (P< 0.001) EXCEPT IN SATTVA. IT ALSO CONFIRMS THAT EQ AND GENERAL HEALTH VARIABLES CORRELATE SIGNIFICANTLY WITH EACH OTHER AND NEGATIVELY WITH TAMAS. EQ AND TAMAS FORM POSITIVE AND NEGATIVE PREDICTORS OF HEALTH RESPECTIVELY. SATTVA CORRELATES POSITIVELY WITH EQ SUGGESTING THAT A SATTVIC PERSONALITY INDICATES BETTER SELF-CONTROL. THIS SUGGESTS THAT, BY IMPROVING GUNA PERSONALITY, LONG-TERM YOGA PRACTICE MAY STABILIZE EQ.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
18  867  42 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	

19 2863  24 YOGA-BASED GUIDED RELAXATION REDUCES SYMPATHETIC ACTIVITY JUDGED FROM BASELINE LEVELS. 35 MALE VOLUNTEERS WHOSE AGES RANGED FROM 20 TO 46 YEARS WERE STUDIED IN TWO SESSIONS OF YOGA-BASED GUIDED RELAXATION AND SUPINE REST. ASSESSMENTS OF AUTONOMIC VARIABLES WERE MADE FOR 15 SUBJECTS, BEFORE, DURING, AND AFTER THE PRACTICES, WHEREAS OXYGEN CONSUMPTION AND BREATH VOLUME WERE RECORDED FOR 25 SUBJECTS BEFORE AND AFTER BOTH TYPES OF RELAXATION. A SIGNIFICANT DECREASE IN OXYGEN CONSUMPTION AND INCREASE IN BREATH VOLUME WERE RECORDED AFTER GUIDED RELAXATION (PAIRED T TEST). THERE WERE COMPARABLE REDUCTIONS IN HEART RATE AND SKIN CONDUCTANCE DURING BOTH TYPES OF RELAXATION. DURING GUIDED RELAXATION THE POWER OF THE LOW FREQUENCY COMPONENT OF THE HEART-RATE VARIABILITY SPECTRUM REDUCED, WHEREAS THE POWER OF THE HIGH FREQUENCY COMPONENT INCREASED, SUGGESTING REDUCED SYMPATHETIC ACTIVITY. ALSO, SUBJECTS WITH A BASELINE RATIO OF LF/HF > 0.5 SHOWED A SIGNIFICANT DECREASE IN THE RATIO AFTER GUIDED RELAXATION, WHILE SUBJECTS WITH A RATIO < OR = 0.5 AT BASELINE SHOWED NO SUCH CHANGE. THE RESULTS SUGGEST THAT SYMPATHETIC ACTIVITY DECREASED AFTER GUIDED RELAXATION BASED ON YOGA, DEPENDING ON THE BASELINE LEVELS.	2002	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
20  705  35 EFFECT OF INTEGRATED APPROACH OF YOGA THERAPY ON AUTONOMIC FUNCTIONS IN PATIENTS WITH TYPE 2 DIABETES. BACKGROUND AND OBJECTIVES: INTEGRATED APPROACH OF YOGA THERAPY (IAYT) HAD SHOWN BENEFICIAL EFFECTS IN THE MANAGEMENT OF TYPE 2 DIABETES MELLITUS (DM). AUTONOMIC DYSFUNCTION IS ONE OF THE MAJOR COMPLICATIONS OF TYPE 2 DM. RESEARCH STUDIES HAVE DEMONSTRATED THAT YOGA CAN MODULATE AUTONOMIC FUNCTIONS. HENCE, THE CURRENT STUDY WAS DESIGNED TO ASSESS THE EFFECT OF IAYT ON AUTONOMIC FUNCTIONS IN TYPE 2 DIABETICS. MATERIALS AND METHODS: 15 PATIENTS OF TYPE 2 DM WITH AGES RANGING FROM 35 TO 60 YEARS WERE RECRUITED FOR THE STUDY. THEY WERE DIAGNOSED WITH TYPE 2 DIABETES FROM 1-YEAR TO 15 YEARS. ASSESSMENTS WERE MADE ON DAY 1 (BEFORE YOGA) AND DAY 7 (AFTER 1-WEEK OF YOGA PRACTICE). HEART RATE VARIABILITY (HRV), BLOOD PRESSURE (BP) RESPONSE TO THE ISOMETRIC HANDGRIP AND HEART RATE RESPONSE TO DEEP BREATHING WERE ASSESSED BEFORE AND AFTER 1-WEEK OF IAYT. RESULTS: THERE WAS A SIGNIFICANT REDUCTION IN FASTING PLASMA GLUCOSE FROM 154.67-130.27 MG/DL (WILCOXON SIGNED RANK TEST, P = 0.029) FOLLOWING 1-WEEK OF IAYT. BP RESPONSE TO ISOMETRIC HAND GRIP IMPROVED SIGNIFICANTLY (WILCOXON SIGNED RANK TEST, P = 0.01). THERE WAS NO STATISTICAL SIGNIFICANT CHANGE IN HRV COMPONENTS AND HEART RATE RESPONSE TO DEEP BREATHING TEST. HOWEVER, THERE WAS A TREND OF INCREASE IN THE LOW FREQUENCY POWER (41.07%), HIGH FREQUENCY POWER (6.29%), TOTAL POWER (5.38%), AND STANDARD DEVIATION OF ALL NN INTERVALS (SDNN) (6.29%). CONCLUSION: THESE FINDINGS SUGGEST THAT, IAYT IMPROVED AUTONOMIC FUNCTIONS IN TYPE 2 DIABETES PATIENTS.	2015
