1 1298 94 HATHA YOGA AND VASCULAR FUNCTION: RESULTS FROM CROSS-SECTIONAL AND INTERVENTIONAL STUDIES. THE AIM OF THIS STUDY WAS TO DETERMINE THE EFFECT OF HATHA YOGA ON ARTERIAL ELASTICITY AND ENDOTHELIAL FUNCTION. FIRST, A CROSS-SECTIONAL STUDY WAS PERFORMED TO DETERMINE WHETHER YOGA PRACTITIONERS WOULD DEMONSTRATE GREATER ARTERIAL COMPLIANCE AND ENDOTHELIUM-DEPENDENT VASODILATION THAN THEIR SEDENTARY PEERS. SECOND, AN INTERVENTION STUDY INVOLVING 13 SEDENTARY MIDDLE-AGED AND OLDER ADULTS (51 +/- 7 YEARS) WAS PERFORMED TO DETERMINE WHETHER 12 WEEKS OF HATHA YOGA WOULD ELICIT INCREASES IN ARTERIAL COMPLIANCE AND ENDOTHELIAL FUNCTION. IN THE CROSS-SECTIONAL STUDY INVOLVING A TOTAL OF 34 SUBJECTS, THERE WERE NO GROUP DIFFERENCES IN BODY FATNESS, BLOOD LIPID AND LIPOPROTEIN CONCENTRATIONS, CAROTID ARTERY COMPLIANCE OR BRACHIAL ARTERY FLOW-MEDIATED DILATION (FMD). HEMOGLOBIN A1C WAS LOWER IN YOGA PRACTITIONERS THAN IN SEDENTARY ADULTS (P < 0.05). TOTAL CHOLESTEROL AND HEMOGLOBIN A1C DECREASED AFTER THE INTERVENTION (P < 0.05) WHILE CAROTID ARTERY COMPLIANCE AND BRACHIAL ARTERY FMD DID NOT CHANGE. THE RESULTS OF BOTH CROSS-SECTIONAL AND INTERVENTIONAL STUDIES INDICATE THAT REGULAR PRACTICE OF HATHA YOGA IS NOT ASSOCIATED WITH IMPROVEMENTS IN VASCULAR FUNCTIONS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
2 1045 50 EFFECTS OF YOGA INTERVENTIONS PRACTISED IN HEATED AND THERMONEUTRAL CONDITIONS ON ENDOTHELIUM-DEPENDENT VASODILATATION: THE BIKRAM YOGA HEART STUDY. NEW FINDINGS: WHAT IS THE CENTRAL QUESTION OF THIS STUDY? DOES THE HEATED PRACTICE ENVIRONMENT ENHANCE THE EFFECTS OF BIKRAM YOGA ON ENDOTHELIUM-DEPENDENT VASODILATATION IN HEALTHY, MIDDLE-AGED ADULTS? WHAT IS THE MAIN FINDING AND ITS IMPORTANCE? THE PRIMARY FINDING FROM THIS INVESTIGATION IS THAT THE HATHA YOGA POSTURES IN THE BIKRAM YOGA SERIES PRODUCE SIMILAR ENHANCEMENTS IN ENDOTHELIUM-DEPENDENT VASODILATATION IN HEALTHY, MIDDLE-AGED ADULTS REGARDLESS OF ENVIRONMENTAL TEMPERATURE. THESE FINDINGS HIGHLIGHT THE EFFICACY OF YOGA POSTURES IN PRODUCING IMPROVEMENTS IN VASCULAR HEALTH AND DOWNPLAY THE NECESSITY OF THE HEATED PRACTICE ENVIRONMENT IN INDUCING VASCULAR ADAPTATIONS. ABSTRACT: WE HAVE PREVIOUSLY DOCUMENTED IMPROVEMENTS IN ENDOTHELIUM-DEPENDENT VASODILATATION WITH A BIKRAM (HOT) YOGA INTERVENTION IN MIDDLE-AGED ADULTS. AT PRESENT, THE EFFECT OF ENVIRONMENTAL TEMPERATURE IN HOT YOGA ON ENDOTHELIAL FUNCTION IS UNKNOWN. THE PURPOSE OF THIS INVESTIGATION WAS TO DETERMINE THE EFFECTS OF BIKRAM YOGA INTERVENTIONS PERFORMED IN HEATED OR THERMONEUTRAL CONDITIONS ON ENDOTHELIUM-DEPENDENT VASODILATATION. FIFTY-TWO SEDENTARY BUT APPARENTLY HEALTHY ADULTS AGED 40-60 YEARS WERE RANDOMLY ASSIGNED TO ONE OF THREE GROUPS: BIKRAM YOGA PRACTISED AT 40.5 DEGREES C (N = 19), BIKRAM YOGA PRACTISED AT 23 DEGREES C (N = 14) OR SEDENTARY TIME CONTROL (N = 19). THE YOGA INTERVENTIONS CONSISTED OF 90 MIN BIKRAM YOGA CLASSES THREE TIMES A WEEK FOR 12 WEEKS. ENDOTHELIUM-DEPENDENT VASODILATATION WAS MEASURED NON-INVASIVELY USING BRACHIAL ARTERY FLOW-MEDIATED DILATATION (FMD). BODY FAT PERCENTAGE DETERMINED VIA DUAL-ENERGY X-RAY ABSORPTIOMETRY WAS SIGNIFICANTLY LOWER IN THE HOT YOGA GROUP AFTER THE INTERVENTION THAN IN THE THERMONEUTRAL YOGA AND CONTROL CONDITIONS. BRACHIAL ARTERY FMD INCREASED (P < 0.05) IN THE THERMONEUTRAL YOGA GROUP AND TENDED TO INCREASE IN THE HOT YOGA GROUP (P = 0.056). NO CHANGES OCCURRED IN THE CONTROL GROUP. THERE WERE NO SIGNIFICANT DIFFERENCES IN FMD CHANGE SCORES BETWEEN GROUPS. WE CONCLUDE THAT BIKRAM YOGA PRACTISED IN THERMONEUTRAL CONDITIONS IMPROVED ENDOTHELIUM-DEPENDENT VASODILATATION IN HEALTHY, MIDDLE-AGED ADULTS. THESE NEW FINDINGS HIGHLIGHT THE EFFECTIVENESS OF HATHA YOGA POSTURES ALONE, IN THE ABSENCE OF A HEATED PRACTICE ENVIRONMENT, IN IMPROVING VASCULAR HEALTH AND ARE OF CLINICAL SIGNIFICANCE GIVEN THE INCREASED PROPENSITY FOR HEAT INTOLERANCE IN AGEING ADULTS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
3  993 19 EFFECTS OF HEATED AND THERMONEUTRAL YOGA INTERVENTIONS ON ARTERIAL STIFFNESS IN MIDDLE-AGED ADULTS. THE STUDY INVESTIGATED THE EFFICACY OF 12 WEEKS OF HEATED AND THERMONEUTRAL BIKRAM YOGA IN REDUCING ARTERIAL STIFFNESS IN MIDDLE-AGED ADULTS. FIFTY-FOUR SEDENTARY ADULTS (AGES 40-60 YEARS) COMPLETED 12 WEEKS OF YOGA AT 40.5 DEGREES C (N = 21), YOGA AT 23 DEGREES C (N = 14) OR TIME CONTROL (N = 19). BRACHIAL-ANKLE PULSE WAVE VELOCITY (PWV) WAS NOT SIGNIFICANTLY ALTERED BY HOT OR THERMONEUTRAL YOGA INTERVENTIONS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
4 2076 45 THE EFFECT OF BIKRAM YOGA ON ENDOTHELIAL FUNCTION IN YOUNG AND MIDDLE-AGED AND OLDER ADULTS. THE PURPOSE OF THIS INVESTIGATION WAS TO DETERMINE IF BIKRAM YOGA, A STYLE OF HEATED HATHA YOGA, WOULD IMPROVE ENDOTHELIAL FUNCTION IN YOUNG AND MIDDLE-AGED AND OLDER, HEALTHY ADULTS. THIS TRIAL WAS PERFORMED IN 36 YOUNG (N = 17) AND MIDDLE-AGED AND OLDER ADULTS (N = 19) WHO COMPLETED 3 WEEKLY BIKRAM YOGA CLASSES FOR 8 WEEKS. HEIGHT, BODY WEIGHT AND BODY COMPOSITION WERE DETERMINED AND ENDOTHELIAL FUNCTION WAS MEASURED NONINVASIVELY USING BRACHIAL ARTERY FLOW-MEDIATED DILATION (FMD) BEFORE AND AFTER THE INTERVENTION. NO CHANGES IN BODY WEIGHT, BMI OR BODY FAT PERCENTAGE OCCURRED AS A RESULT OF THE INTERVENTION IN EITHER GROUP. BRACHIAL ARTERY FMD WAS SIGNIFICANTLY INCREASED IN MIDDLE-AGED AND OLDER (P < 0.05) BUT NOT IN YOUNG ADULTS AS A RESULT OF THE INTERVENTION. THE RESULTS DEMONSTRATE THAT A RELATIVELY SHORT-TERM BIKRAM YOGA PRACTICE MIGHT SIGNIFICANTLY IMPROVE VASCULAR ENDOTHELIAL FUNCTION IN MIDDLE-AGED AND OLDER ADULTS. WHILE APPARENTLY HEALTHY INDIVIDUALS IN THIS STUDY EXPERIENCED NO ADVERSE EVENTS, THOSE WITH PREEXISTING CONDITIONS SHOULD TAKE CAUTION AND CONSULT WITH A PHYSICIAN PRIOR TO ENGAGING IN THIS STYLE OF YOGA.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
5 2072 39 THE EFFECT OF A SIX-WEEK PROGRAM OF YOGA AND MEDITATION ON BRACHIAL ARTERY REACTIVITY: DO PSYCHOSOCIAL INTERVENTIONS AFFECT VASCULAR TONE? BACKGROUND: CHRONIC STRESS IS ESTIMATED TO INCREASE THE RISK OF CARDIOVASCULAR (CV) EVENTS TWO-FOLD. ALTHOUGH STRESS REDUCTION HAS BEEN LINKED TO A REDUCTION IN CV EVENTS, LITTLE IS KNOWN REGARDING ITS EXACT MECHANISM OF BENEFIT. HYPOTHESIS: YOGA AND MEDITATION WILL IMPROVE PARAMETERS OF ENDOTHELIAL FUNCTION. METHODS: WE EXAMINED THE EFFECTS OF YOGA AND MEDITATION ON HEMODYNAMIC AND LABORATORY PARAMETERS AS WELL AS ON ENDOTHELIAL FUNCTION IN A 6-WEEK PILOT STUDY. SYSTOLIC AND DIASTOLIC BLOOD PRESSURES, HEART RATE, BODY MASS INDEX (BMI), FASTING GLUCOSE, LIPIDS, HS C-REACTIVE PROTEIN (CRP), AND ENDOTHELIAL FUNCTION (AS ASSESSED BY BRACHIAL ARTERY REACTIVITY) WERE ALL STUDIED AT BASELINE AND AFTER 6 WEEKS OF YOGA PRACTICE. RESULTS: A COURSE IN YOGA AND MEDITATION WAS GIVEN TO THE SUBJECTS FOR 1.5 H THREE TIMES WEEKLY FOR 6 WEEKS AND SUBJECTS WERE INSTRUCTED TO CONTINUE THEIR EFFORTS AT HOME. THIS PROSPECTIVE COHORT STUDY INCLUDED 33 SUBJECTS (MEAN AGE 55 +/- 11 YEARS) BOTH WITH (30%) AND WITHOUT (70%) ESTABLISHED CORONARY ARTERY DISEASE (CAD). THERE WERE SIGNIFICANT REDUCTIONS IN BLOOD PRESSURE, HEART RATE, AND BMI IN THE TOTAL COHORT WITH YOGA. NONE OF THE LABORATORY PARAMETERS CHANGED SIGNIFICANTLY WITH YOGA. FOR THE TOTAL COHORT THERE WAS NO SIGNIFICANT IMPROVEMENT IN ENDOTHELIAL-DEPENDENT VASODILATATION WITH YOGA TRAINING AND MEDITATION COMPARED WITH BASELINE (16.7% RELATIVE IMPROVEMENT FROM 7.2-8.4%; P = 0.3). IN THE GROUP WITH CAD, ENDOTHELIAL-DEPENDENT VASODILATATION IMPROVED 69% WITH YOGA TRAINING (6.38-10.78%; P = 0.09). CONCLUSION: YOGA AND MEDITATION APPEAR TO IMPROVE ENDOTHELIAL FUNCTION IN SUBJECTS WITH CAD.	2006	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
6  276 33 ADDITIONAL IMPROVEMENT OF RESPIRATORY TECHNIQUE ON VASCULAR FUNCTION IN HYPERTENSIVE POSTMENOPAUSAL WOMEN FOLLOWING YOGA OR STRETCHING VIDEO CLASSES: THE YOGINI STUDY. BACKGROUND: HYPERTENSION REMAINS HIGHLY PREVALENT IN POSTMENOPAUSAL WOMEN, ALONG WITH VASCULAR DYSFUNCTION AND INCREASED OXIDATIVE STRESS. IN SUCH CONTEXT, REGULAR EXERCISES, YOGA PRACTICE, AND SLOW BREATHING HAVE BEEN RECOMMENDED TO TREAT HYPERTENSION. HOWEVER, THE EFFECTS OF THE MULTIPLE COMPONENTS OF YOGA, INCLUDING THE RESPIRATORY TECHNIQUES INVOLVED IN THE PRACTICE, ON HYPERTENSION AND ON VASCULAR AND ENDOTHELIAL FUNCTION HAVE NEVER BEEN EVALUATED. OBJECTIVE: THIS STUDY AIMED TO INVESTIGATE THE ADDITIONAL EFFECTS OF RESPIRATORY TECHNIQUE ON VASCULAR FUNCTION AND OXIDATIVE STRESS PROFILE IN HYPERTENSIVE POSTMENOPAUSAL WOMEN (HPMWS) FOLLOWING YOGA OR STRETCHING VIDEO CLASSES. STUDY DESIGN: HYPERTENSIVE POSTMENOPAUSAL WOMEN WERE RECRUITED AND RANDOMIZED FOR 12 WEEKS, TWICE A WEEK, OF SUPERVISED YOGA OR STRETCHING VIDEO CLASSES OF 75 MIN FOR 12 WEEKS ASSOCIATED OR NOT WITH RESPIRATORY TECHNIQUE. BASELINE AND POST-INTERVENTION MEASUREMENTS INCLUDED PULSE WAVE VELOCITY (PWV), FLOW-MEDIATED DILATION (FMD), AND OXIDATIVE STRESS PARAMETERS. HYPERTENSIVE POSTMENOPAUSAL WOMEN (59 +/- 0.7 YEARS) WHO ENDED THE PROTOCOL WERE DISTRIBUTED INTO THREE GROUPS: (1) CONTROL GROUP (YOGA OR STRETCHING, C, N = 14); (2) YOGA + RESPIRATORY TECHNIQUE (Y+, N = 10); (3) STRETCHING + RESPIRATORY TECHNIQUE (S+, N = 9). RESULTS: DIASTOLIC BLOOD PRESSURE AND FMD [BASELINE: C: 6.94 +/- 1.97%, Y+: 7.05 +/- 1.65%, AND S+: 3.54 +/- 2.01% VS. POST: C: 16.59 +/- 3.46% (P = 0.006), Y+: 13.72 +/- 2.81% (P = 0.005), AND S+: 11.79 +/- 0.99% (P = 0.0001)] HAVE SIGNIFICANTLY INCREASED IN ALL GROUPS WHEN BASELINE AND POST-PRACTICE VALUES WERE COMPARED. HOWEVER, RESTING HEART RATE AND PWV [BASELINE: Y+: 10.44 +/- 3.69 AND S+: 9.50 +/- 0.53 M/S VS. POST: Y+: 9.45 +/- 0.39 (P = 0.003) AND S+: 8.02 +/- 0.47 M/S (P = 0.003)] DECREASED SIGNIFICANTLY ONLY IN THE Y+ AND S+ GROUPS (BASELINE VS. POST). SYSTEMIC ANTIOXIDANT ENZYME ACTIVITIES (SUPEROXIDE DISMUTASE AND CATALASE) INCREASED IN ALL GROUPS, AND HYDROGEN PEROXIDE AND LIPOPEROXIDATION REDUCED IN Y+ AND S+ (BASELINE VS. POST). CONCLUSIONS: TWELVE WEEKS OF YOGA OR STRETCHING VIDEO CLASSES PROMOTED POSITIVE CHANGES IN SEVERAL OUTCOMES GENERALLY REGARDED AS CARDIOVASCULAR RISK FACTORS IN HPMWS, AND THESE CHANGES WERE EVEN MORE PRONOUNCED BY THE ASSOCIATION WITH RESPIRATORY TECHNIQUE.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
7  370 31 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

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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
9 2759 24 YOGA PRACTITIONERS EXHIBIT HIGHER PARASYMPATHETIC ACTIVITY AND BAROREFLEX SENSITIVITY AND BETTER ADAPTABILITY TO 40 MM HG LOWER-BODY NEGATIVE PRESSURE. YOGA HAS BEEN SHOWN TO IMPROVE AUTONOMIC CONDITIONING IN HUMANS, AS EVIDENCED BY THE ENHANCEMENT OF PARASYM-PATHETIC ACTIVITY AND BAROREFLEX SENSITIVITY. THEREFORE, WE HYPOTHESIZED THAT THE EXPERIENCE OF YOGA MAY RESULT IN ADAPTATION TO ACUTE HEMODYNAMIC CHANGES. TO DECIPHER THE LONG-TERM EFFECTS OF YOGA ON CARDIOVASCULAR VARIABILITY, YOGA PRACTITIONERS WERE COMPARED TO YOGA-NAIVE SUBJECTS DURING EXPOSURE TO -40 MM HG LOWER-BODY NEGATIVE PRESSURE (LBNP). A COMPARATIVE STUDY WAS CONDUCTED ON 40 YOGANAIVE SUBJECTS AND 40 YOGA PRACTITIONERS WITH AN AVERAGE AGE OF 31.08 +/- 7.31 YEARS AND 29.93 +/- 7.57 YEARS, RESPECTIVELY. HEART RATE VARIABILITY, BLOOD PRESSURE VARIABILITY, BAROREFLEX SENSITIVITY, AND CORRELATION BETWEEN SYSTOLIC BLOOD PRESSURE AND RR INTERVAL WERE EVALUATED AT REST AND DURING LBNP. IN YOGA PRACTITIONERS, THE HEART RATE WAS LOWER IN SUPINE REST (P = 0.011) AND DURING LBNP (P = 0.043); THE PNN50 MEASURE OF HEART RATE VARIABILITY WAS HIGHER IN SUPINE REST (P = 0.011) AND DURING LBNP (P = 0.034). THE YOGA PRACTITIONERS' STANDARD DEVIATION OF SUCCESSIVE BEAT-TO-BEAT BLOOD PRESSURE INTERVALS OF SYSTOLIC BLOOD PRESSURE VARIABILITY WAS LOWER IN SUPINE REST (P = 0.034) AND DURING LBNP (P = 0.007), WITH HIGHER SEQUENCE BAROREFLEX SENSITIVITY (P = 0.019) AND ~ HIGH-FREQUENCY BAROREFLEX SENSITIVITY. MEAN SYSTOLIC BLOOD PRESSURE AND RR INTERVAL WERE INVERSELY CORRELATED IN THE YOGA GROUP (R = -0.317, P = 0.049). THE YOGA PRACTITIONERS EXHIBITED HIGHER PARASYMPATHETIC ACTIVITY AND BAROREFLEX SENSITIVITY WITH LOWER SYSTOLIC BLOOD PRESSURE VARIABILITY, INDICATING BETTER ADAPTABILITY TO LBNP COMPARED TO THE YOGA-NAIVE GROUP. OUR FINDINGS INDICATE THAT THE YOGA MODULE WAS HELPFUL IN CONDITIONS OF HYPOVOLEMIA IN HEALTHY SUBJECTS; IT IS PROPOSED TO BE BENEFICIAL IN CLINICAL CONDITIONS ASSOCIATED WITH SYMPATHETIC DOMINANCE, IMPAIRED BARORE-FLEX SENSITIVITY, AND ORTHOSTATIC INTOLERANCE.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
10 2065 36 THE CARDIOVASCULAR VARIABILITY DURING TRANSIENT 6 DEGREES HEAD DOWN TILT AND SLOW BREATHING IN YOGA EXPERIENCED HEALTHY INDIVIDUALS. OBJECTIVE: THE INTERVENTION OF YOGA HAS BEEN SHOWN TO IMPROVE AUTONOMIC CONDITIONING IN HUMANS AND BETTER ADAPTABILITY TO ORTHOSTATIC CHALLENGES. SIMILARLY, SLOW BREATHING AT 0.1 HZ AKIN TO PRANAYAMA ALSO INCREASES BAROREFLEX SENSITIVITY (BRS). HENCE, WE INTENDED TO INVESTIGATE WHETHER YOGA PRACTITIONERS HAVE DIFFERENT AUTONOMIC RESPONSES AT REST,DURING SLOW DEEP BREATHINGAS WELL AS DURING 6 DEGREES HEAD DOWN TILT (HDT) COMPARED TO NAIVE GROUP INDIVIDUALS. AIM: THE AIM OF THE STUDY WAS TO EVALUATE THE ACUTE EFFECTS OF SLOW BREATHING ON CARDIOVASCULAR VARIABILITY DURING HDT IN YOGA PRACTITIONERS COMPARED TO YOGA-NAIVE INDIVIDUALS. SETTINGS AND DESIGN: THIS WAS A COMPARATIVE STUDY WITH REPEATED MEASURES DESIGN CONDUCTED IN AUTONOMIC FUNCTION TEST LAB OF THE DEPARTMENT OF PHYSIOLOGY, ALL INDIA INSTITUTE OF MEDICAL SCIENCES, NEW DELHI, INDIA. MATERIALS AND METHODS: TIME DOMAIN AND FREQUENCY DOMAIN PARAMETERS OF HEART RATE VARIABILITY, BLOOD PRESSURE VARIABILITY (BPV), AND BRS WERE EVALUATED DURING 6 DEGREES HDT AND SLOW BREATHING AT 0.1 HZ ON FORTY YOGA-NAIVE INDIVIDUALS AND FORTY YOGA PRACTITIONERS WITH AN AVERAGE AGE OF 31.08 +/- 7.31 YEARS AND 29.93 +/- 7.57 YEARS, RESPECTIVELY. ALL OF THE PARTICIPANTS WERE HEALTHY. STATISTICAL ANALYSIS USED: GENERAL LINEAR MIXED MODEL ANOVA WAS APPLIED WITH YOGA EXPERIENCE AS A BETWEEN-GROUP FACTOR IN REPEATED MEASURES. INDEPENDENT SAMPLE T-TEST WAS APPLIED FOR BETWEEN GROUP COMPARISON OF RESPIRATORY RATE, DEMOGRAPHIC, AND ANTHROPOMETRIC DATA. P <0.05 IS CONSIDERED STATISTICALLY SIGNIFICANT. RESULTS: BETWEEN-GROUP COMPARISON DURING HDT WITH SPONTANEOUS BREATHING HAS SHOWN A SIGNIFICANTLY LOWER HEART RATE (P = 0.004) WITH HIGHER RR INTERVAL (RRI) (P = 0.002) AND PNN50% (P = 0.019) IN YOGA PRACTITIONERS. THE SEQUENCE BRS (P < 0.0001) AND ALPHA LOW FREQUENCY (LF) OF SPECTRAL BRS (P = 0.035) WERE ALSO SIGNIFICANTLY HIGHER IN THE YOGA GROUP COMPARED TO THE NAIVE GROUP. SIMILARLY, DURING HDT WITH SLOW BREATHING, THE HEART RATE WAS LOWER (P = 0.01); WITH HIGHER RRI (P = 0.009); PNN50% (P = 0.048). STANDARD DEVIATION OF SUCCESSIVE RR INTERVAL DIFFERENCE OF SYSTOLIC BPV WAS LOWER (P = 0.024) WITH HIGHER SEQUENCE BRS (P = 0.001) AND ALPHA LF OF SPECTRAL BRS (P = 0.002) IN YOGA GROUP THAN NAIVE GROUP. CONCLUSION: THE YOGA EXPERIENCED INDIVIDUALS EXHIBIT HIGHER RESTING PARASYMPATHETIC ACTIVITY, LOWER SYSTOLIC BPV, AND HIGHER BRS THAN NAIVE TO YOGA INDIVIDUALS. IT IS INFERRED FROM THE FINDINGS THAT YOGA PRACTITIONERS WERE BETTER ADAPTED TO TRANSIENT CEPHALAD FLUID SHIFT THAT HAPPENS DURING 6 DEGREES HDT. FURTHERMORE, ACUTE SLOW BREATHING DURING 6 DEGREES HDT REDUCED THE SYSTOLIC BLOOD PRESSURE IN ALL THE PARTICIPANTS SUGGESTING THE BENEFICIAL ROLE OF SLOW BREATHING DURING EXPOSURE TO EXTREME CONDITIONS SUCH AS MICROGRAVITY WHICH MIGHT HELP IN THE PREVENTION OF ADVERSE EFFECTS OF CEPHALAD FLUID SHIFT DURING LONG-TERM WEIGHTLESSNESS AND MAINTAIN THE ASTRONAUT HEALTH. FUTURE MECHANISTIC STUDIES WITH ACTIVE YOGA INTERVENTION ARE NECESSARY TO UNDERSTAND THE ADAPTIVE MECHANISMS INVOLVING CENTRAL AND VASCULAR MODULATIONS CONTRIBUTING TO EITHER ATTENUATION OR ACCENTUATION OF THE CARDIOVAGAL BAROREFLEX DURING HDT AND SLOW BREATHING IN HEALTHY INDIVIDUALS.	2021	

11 1322 34 HEMODYNAMIC AND PRESSOR RESPONSES TO COMBINATION OF YOGA AND BLOOD FLOW RESTRICTION. A COMBINATION OF YOGA AND BLOOD FLOW RESTRICTION, EACH OF WHICH ELICITS MARKED PRESSOR RESPONSES, MAY FURTHER INCREASE BLOOD PRESSURE AND MYOCARDIAL OXYGEN DEMAND. TO DETERMINE THE IMPACT OF A COMBINATION OF YOGA AND BLOOD FLOW RESTRICTION ON HEMODYNAMIC RESPONSES, TWENTY YOUNG HEALTHY PARTICIPANTS PERFORMED 20 YOGA POSES WITH/WITHOUT BLOOD FLOW RESTRICTION BANDS PLACED ON BOTH LEGS. AT BASELINE, THERE WERE NO SIGNIFICANT DIFFERENCES IN ANY OF THE VARIABLES BETWEEN THE BLOOD FLOW RESTRICTION AND NON-BLOOD FLOW RESTRICTION CONDITIONS. BLOOD PRESSURE AND HEART RATE INCREASED IN RESPONSE TO THE VARIOUS YOGA POSES (P<0.01) BUT WERE NOT DIFFERENT BETWEEN THE BLOOD FLOW RESTRICTION AND NON-BLOOD FLOW RESTRICTION CONDITIONS. RATE-PRESSURE PRODUCTS, AN INDEX OF MYOCARDIAL OXYGEN DEMAND, INCREASED SIGNIFICANTLY DURING YOGA EXERCISES WITH NO SIGNIFICANT DIFFERENCES BETWEEN THE TWO CONDITIONS. RATING OF PERCEIVED EXERTION WAS NOT DIFFERENT BETWEEN THE CONDITIONS. BLOOD LACTATE CONCENTRATION WAS SIGNIFICANTLY GREATER AFTER PERFORMING YOGA WITH BLOOD FLOW RESTRICTION BANDS (P=0.007). CARDIO-ANKLE VASCULAR INDEX, AN INDEX OF ARTERIAL STIFFNESS, DECREASED SIMILARLY AFTER YOGA EXERCISE IN BOTH CONDITIONS WHILE FLOW-MEDIATED DILATION REMAINED UNCHANGED. IN CONCLUSION, THE USE OF LOWER BODY BLOOD FLOW RESTRICTION BANDS IN COMBINATION WITH YOGA DID NOT RESULT IN ADDITIVE OR SYNERGISTIC HEMODYNAMIC AND PRESSOR RESPONSES.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
12 2075 43 THE EFFECT OF BIKRAM YOGA ON ARTERIAL STIFFNESS IN YOUNG AND OLDER ADULTS. BACKGROUND AND OBJECTIVE: BIKRAM YOGA IS THE MOST POPULAR FORM OF HOT YOGA, DESPITE THE LIMITED INFORMATION AVAILABLE ON ITS CARDIOVASCULAR BENEFITS. THIS STUDY SOUGHT TO DETERMINE THE EFFECT OF BIKRAM YOGA ON ARTERIAL STIFFNESS AND INSULIN RESISTANCE IN YOUNG AND OLDER ADULTS. METHODS: TWENTY-FOUR YOUNG (MEAN AGE+/-STANDARD DEVIATION, 30+/-1 YEARS) AND 18 MIDDLE-AGED AND OLDER (MEAN AGE, 53+/-2 YEARS) ADULTS COMPLETED AN 8-WEEK BIKRAM YOGA INTERVENTION. BIKRAM YOGA CLASSES WERE PERFORMED FOR 90 MINUTES PER SESSION, THREE TIMES PER WEEK, IN A ROOM HEATED TO 40.5 DEGREES C WITH 40%--60% RELATIVE HUMIDITY. RESULTS: BODY MASS, BODY FAT PERCENTAGE, BLOOD PRESSURE, AND FASTING BLOOD GLUCOSE AND TRIGLYCERIDE CONCENTRATIONS DID NOT SIGNIFICANTLY CHANGE AS A RESULT OF THE INTERVENTION IN EITHER THE YOUNG OR THE OLDER GROUP. TRUNK FLEXIBILITY, AS MEASURED BY THE SIT-AND-REACH TEST, INCREASED IN BOTH GROUPS (P<0.01). TOTAL (P<0.05) AND LOW-DENSITY LIPOPROTEIN CHOLESTEROL (P<0.05) LEVELS, PLASMA INSULIN CONCENTRATIONS (P<0.01), AND SCORES ON THE HOMEOSTATIC MODEL OF THE ASSESSMENT OF INSULIN RESISTANCE (P<0.01) DECREASED IN OLDER ADULTS, WHEREAS TOTAL AND HIGH-DENSITY LIPOPROTEIN CHOLESTEROL CONCENTRATIONS WERE REDUCED IN YOUNG ADULTS (ALL P<0.05). CAROTID ARTERY COMPLIANCE (P<0.05) WAS INCREASED AND BETA-STIFFNESS INDEX DECREASED IN YOUNG (P<0.05) BUT NOT IN OLDER ADULTS. CAROTID PULSE PRESSURE DID NOT SIGNIFICANTLY CHANGE IN EITHER GROUP. CONCLUSION: A RELATIVELY SHORT-TERM BIKRAM YOGA INTERVENTION IMPROVED ARTERIAL STIFFNESS IN YOUNG BUT NOT OLDER ADULTS AND SIGNIFICANTLY REDUCED INSULIN RESISTANCE INDEX IN OLDER BUT NOT YOUNG ADULTS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
13  324 23 ANTHROPOMETRIC, BIOCHEMICAL AND CLINICAL PARAMETERS IN CLIMACTERIC YOGA PRACTITIONERS. OBJECTIVE: THIS STUDY AIMED TO EVALUATE ANTHROPOMETRIC, BIOCHEMICAL AND CLINICAL PARAMETERS IN CLIMACTERIC YOGA PRACTITIONERS. METHODS: THIS STUDY INVESTIGATED 108 CLIMACTERIC WOMEN. WE RECRUITED 28 WOMEN BETWEEN 40 AND 65 YEARS OLD WHO STARTED YOGA PRACTICES IN PREMENOPAUSE AND HAD ALREADY PRACTICED FOR AT LEAST 5 YEARS. AS CONTROLS, WE SELECTED 30 PHYSICAL ACTIVITY (PA) PRACTITIONERS WHO HAD PRACTICED FOR AT LEAST 5 YEARS AND 50 SEDENTARY WOMEN IN THE SAME AGE RANGE. WE CONDUCED ANTHROPOMETRIC, BIOCHEMICAL AND BLOOD PRESSURE MEASUREMENTS. RESULTS: THE YOGA GROUP HAD SIGNIFICANTLY LOWER FASTING BLOOD GLUCOSE THAN THE PA PRACTITIONERS AND SEDENTARY WOMEN. YOGA PRACTITIONERS ALSO HAD LOWER WEIGHT, BODY MASS INDEX, WAIST CIRCUMFERENCE, BODY FAT PERCENTAGE AND WAIST-TO-HEIGHT RATIO; HIGHER LEVELS OF HIGH-DENSITY LIPOPROTEIN CHOLESTEROL; LOWER LEVELS OF TRIGLYCERIDES, INSULIN, HOMEOSTASIS MODEL ASSESSMENT OF INSULIN RESISTANCE, URIC ACID, APOLIPOPROTEIN B AND HIGH-SENSITIVITY C-REACTIVE PROTEIN; AND LOWER FREQUENCY OF METABOLIC SYNDROME, LIPID ACCUMULATION PRODUCT, VISCERAL ADIPOSITY INDEX AND SYSTOLIC BLOOD PRESSURE THAN THE SEDENTARY WOMEN. CONCLUSION: YOGA PRACTITIONERS HAD LOWER GLUCOSE SERUM CONCENTRATIONS THAN THE PA PRACTITIONERS AND SEDENTARY WOMEN. OVERALL, THE YOGA GROUP ALSO HAD BETTER ANTHROPOMETRIC, BIOCHEMICAL AND CLINICAL VARIABLES THAN THE OTHER GROUPS. ALTHOUGH FURTHER INVESTIGATION IS REQUIRED, YOGA PRACTICE IN PREMENOPAUSE SEEMS TO BE BENEFICIAL FOR WOMEN WHEN THEY REACH MENOPAUSE.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
14  658 35 EFFECT OF 1-WEEK YOGA-BASED RESIDENTIAL PROGRAM ON CARDIOVASCULAR VARIABLES OF HYPERTENSIVE PATIENTS: A COMPARATIVE STUDY. INTRODUCTION: HYPERTENSION (HTN) IS AN IMPORTANT PUBLIC HEALTH CONCERN AND A LEADING CAUSE OF MORBIDITY AND MORTALITY WORLDWIDE. YOGA IS A FORM OF MIND-BODY MEDICINE SHOWN TO BE EFFECTIVE IN CONTROLLING BLOOD PRESSURE (BP) AND REDUCES CARDIAC RISK FACTORS IN HTN. INTEGRATED APPROACH OF YOGA THERAPY (IAYT) IS A RESIDENTIAL YOGA-BASED LIFESTYLE INTERVENTION PROVEN TO BE BENEFICIAL IN SEVERAL HEALTH CONDITIONS. AIM: TO STUDY THE EFFICACY OF 1 WEEK OF RESIDENTIAL IAYT INTERVENTION ON CARDIOVASCULAR PARAMETERS IN HYPERTENSIVE PATIENTS. METHODOLOGY: TWENTY HYPERTENSIVE INDIVIDUALS (7 FEMALES) WITHIN AGE RANGE BETWEEN 30 AND 60 YEARS (AVERAGE; 46.62 +/- 9.9 YEARS), WHO UNDERWENT 1 WEEK OF IAYT TREATMENT FOR HTN, WERE COMPARED WITH AGE- GENDER-MATCHED NON-IAYT GROUP (5 FEMALES; AVERAGE AGE; 47.08 +/- 9.69 YEARS) IN TERMS OF SYSTOLIC BP (SBP), DIASTOLIC BP (DBP), MEAN ARTERIAL PRESSURE (MAP), CARDIAC OUTPUT (CO), STROKE VOLUME (SV), BAROREFLEX SENSITIVITY (BRS), AND TOTAL PERIPHERAL VASCULAR RESISTANCE (TPVR), IAYT PROGRAM CONSISTED OF SESSIONS OF ASANAS, BREATHING PRACTICES, MEDITATION AND RELAXATION TECHNIQUES, LOW SALT, LOW-CALORIE DIET, DEVOTIONAL SESSION, AND COUNSELING. INDIVIDUALS IN NON-IAYT GROUP FOLLOWED THEIR NORMAL ROUTINE. ALL THE VARIABLES WERE ASSESSED BEFORE AND AFTER ONE WEEK. DATA WERE ANALYZED USING SPSS VERSION 16. RM-ANOVA WAS APPLIED TO ASSESS WITHIN GROUP AND BETWEEN GROUP CHANGES AFTER INTERVENTION. RESULTS: THERE WAS A SIGNIFICANT IMPROVEMENT IN SBP (P = 0.004), DBP (P = 0.008), MAP (0.03), BRS (P < 0.001), AND TPVR (P = 0.007) IN IAYT, GROUP WHEREAS IN CONTROL GROUP, WE DID NOT FIND SIGNIFICANT DIFFERENCE IN ANY OF THE VARIABLES. BETWEEN-GROUP COMPARISON SHOWED A SIGNIFICANT IMPROVEMENT IN SBP (P = 0.038), BRS (P = 0.034), AND TPVR (P = 0.015) IN IAYT GROUP AS COMPARED TO NON-IAYT GROUP. CONCLUSION: ONE-WEEK IAYT INTERVENTION SHOWED AN IMPROVEMENT IN BAROREFLEX SENSITIVITY, SYSTOLIC BP, AND TOTAL PERIPHERAL VASCULAR RESISTANCE IN HYPERTENSIVE PATIENTS. HOWEVER, FURTHER RANDOMIZED CONTROL TRIALS NEED TO BE PERFORMED TO CONFIRM THE PRESENT FINDINGS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
15 2242 36 THE INFLUENCE OF PHYSICAL ACTIVITY AND YOGA ON CENTRAL ARTERIAL STIFFNESS. PURPOSE: CENTRAL ARTERIAL STIFFNESS IS AN ACCEPTED RISK FACTOR FOR CARDIOVASCULAR DISEASE. WHILE AEROBIC ACTIVITY IS ASSOCIATED WITH REDUCED STIFFNESS THE INFLUENCE OF PRACTICING YOGA IS UNKNOWN. THE AIMS OF THIS STUDY WERE TO: 1) EVALUATE ARTERIAL STIFFNESS IN MIDDLE-AGED ADULTS WHO REGULARLY PRACTICED YOGA, PERFORMED REGULAR EXERCISE, OR WERE INACTIVE, 2) EVALUATE THE REPRODUCIBILITY OF ARTERIAL STIFFNESS MEASURED IN THE LEFT AND RIGHT CAROTID ARTERY AND BY PULSE WAVE VELOCITY (PWV). METHODS: TWENTY SIX HEALTHY SUBJECTS (MALE AND FEMALE, 40-65 YRS OLD) WERE TESTED ON TWO SEPARATE DAYS. CAROTID ARTERY DISTENSIBILITY (DC) WAS MEASURED WITH ULTRASOUND. PHYSICAL ACTIVITY WAS DETERMINED BY QUESTIONNAIRE. RESULTS: YOGA AND AEROBIC SUBJECTS HAD SIMILAR PHYSICAL ACTIVITY LEVELS. YOGA AND AEROBIC GROUPS WERE NOT DIFFERENT IN EITHER DC (P = 0.26) OR PWV (P = 0.21). THE SEDENTARY GROUP HAD LOWER DC AND HIGHER PWV COMPARED TO THE AEROBIC AND YOGA GROUPS (BOTH, P < 0.001). STIFFNESS MEASURES WERE RELIABLE DAY TO DAY (COEFFICIENTS OF VARIATION APPROXIMATELY 2.5%) AND SIMILAR BETWEEN LEFT AND RIGHT ARTERIES (CV = 2.2%). CONCLUSION: PHYSICAL ACTIVITY WAS A STRONG PREDICTOR OF BOTH MEASURES OF ARTERIAL STIFFNESS, ALTHOUGH OTHER FACTORS SUCH AS NUTRITIONAL STATUS NEED TO BE ACCOUNTED FOR.

16 1030 34 EFFECTS OF YOGA EXERCISE ON SERUM ADIPONECTIN AND METABOLIC SYNDROME FACTORS IN OBESE POSTMENOPAUSAL WOMEN. OBJECTIVE: REGULAR AND CONTINUOUS YOGA EXERCISE IS ONE OF THE MOST IMPORTANT NONPHARMACOLOGICAL METHODS OF IMPROVING SERUM LIPID CONCENTRATIONS, ADIPOSE TISSUE, AND METABOLIC SYNDROME FACTORS. THE PURPOSE OF THIS STUDY WAS TO ANALYZE THE EFFECTS OF YOGA EXERCISE ON SERUM ADIPONECTIN AND METABOLIC SYNDROME FACTORS IN OBESE POSTMENOPAUSAL KOREAN WOMEN. METHODS: SIXTEEN HEALTHY POSTMENOPAUSAL WOMEN AGED 54.50 +/- 2.75 YEARS WITH MORE THAN 36% BODY FAT WERE RANDOMLY ASSIGNED TO EITHER A YOGA EXERCISE GROUP (N = 8) OR TO A "NO EXERCISE" CONTROL GROUP (N = 8). THE VARIABLES OF BODY COMPOSITION, VISCERAL FAT, SERUM ADIPONECTIN, AND METABOLIC SYNDROME FACTORS WERE MEASURED IN ALL THE PARTICIPANTS BEFORE AND AFTER THE 16-WEEK STUDY. RESULTS: BODY WEIGHT, PERCENTAGE OF BODY FAT, LEAN BODY MASS, BODY MASS INDEX, WAIST CIRCUMFERENCE, AND VISCERAL FAT AREA HAD SIGNIFICANTLY DECREASED. HIGH-DENSITY LIPOPROTEIN CHOLESTEROL AND ADIPONECTIN HAD SIGNIFICANTLY INCREASED, BUT TOTAL CHOLESTEROL, TRIGLYCERIDE, LOW-DENSITY LIPOPROTEIN CHOLESTEROL, BLOOD PRESSURE, INSULIN, GLUCOSE, AND HOMOEOSTASIS MODEL ASSESSMENT-INSULIN RESISTANCE HAD SIGNIFICANTLY DECREASED. SERUM ADIPONECTIN CONCENTRATIONS WERE SIGNIFICANTLY CORRELATED WITH WAIST CIRCUMFERENCE, HIGH-DENSITY LIPOPROTEIN CHOLESTEROL, DIASTOLIC BLOOD PRESSURE, AND HOMOEOSTASIS MODEL ASSESSMENT-INSULIN RESISTANCE IN THE POSTYOGA EXERCISE GROUP. CONCLUSIONS: OUR FINDINGS INDICATE THAT YOGA EXERCISE IMPROVES ADIPONECTIN LEVEL, SERUM LIPIDS, AND METABOLIC SYNDROME RISK FACTORS IN OBESE POSTMENOPAUSAL WOMEN. CONSEQUENTLY, YOGA EXERCISE WILL BE EFFECTIVE IN PREVENTING CARDIOVASCULAR DISEASE CAUSED BY OBESITY IN OBESE POSTMENOPAUSAL KOREAN WOMEN.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
17  263 31 ACUTE CARDIOVASCULAR RESPONSES TO A SESSION OF BIKRAM YOGA: A PILOT UNCONTROLLED TRIAL. INTRODUCTION: MAIN CARDIOVASCULAR PARAMETERS SUCH AS HEART RATE (HR), BLOOD PRESSURE, AND MYOCARDIAL OXYGEN CONSUMPTION (MOC) ARE TIGHTLY REGULATED BY A MULTIFACTORIAL, NONLINEAR CONTROL SYSTEM. INCREASED HR BECAUSE OF PHYSICAL ACTIVITY IS OFTEN ACCOMPANIED BY AN INCREASE IN BLOOD PRESSURE. POSTURAL CHANGES HAVE AN EFFECT ON THE BARORECEPTORS, AND STRETCHING EXERCISES AND ISOMETRIC CONTRACTIONS MODULATE MUSCLE MECHANORECEPTORS ELICITING INCREASES IN BLOOD PRESSURE. HOWEVER, A HOT ENVIRONMENT INCREASES THE CORE TEMPERATURE INDUCING VASODILATION AND PLASMA VOLUME CHANGES THAT MIGHT CONTRIBUTE TO A DROP IN BLOOD PRESSURE. DURING THE PRACTICE OF BIKRAM YOGA, ALL THESE FACTORS CONVERGE AND LITTLE IS KNOWN ABOUT THE RESULTING CHANGES IN BLOOD PRESSURE AND MOC. METHODS: SIXTEEN APPARENTLY HEALTHY FEMALE VOLUNTEERS, REGULAR PRACTITIONERS OF BIKRAM YOGA, WERE EVALUATED DURING A 90 MIN SESSION. SYSTOLIC BLOOD PRESSURE (SBP) AND DIASTOLIC BLOOD PRESSURE (DBP) WERE MEASURED IMMEDIATELY AFTER EACH POSTURE AND HR WAS MEASURED CONTINUOUSLY DURING THE PRACTICE. RESULTS: HR AND ESTIMATED MOC INCREASED SIGNIFICANTLY OVER BASELINE DURING THE EXERCISE (+62.3% AND +63.6%, RESPECTIVELY). HR MEAN VALUE ACROSS THE ENTIRE BIKRAM YOGA SESSION WAS 126.6 +/- 14.3 BPM REACHING A MAXIMUM OF 168.1 +/- 20.2 BPM. SBP WAS NOT SIGNIFICANTLY INCREASED OVER BASELINE AT ANY TIME DURING THE PRACTICE WITH A MEAN VALUE OF 117.0 +/- 10.1 MMHG AND DBP WAS SIGNIFICANTLY DECREASED OVER BASELINE MOST OF THE TIME (-10.1%, MEAN 71.2 +/- 7.3 MMHG) WITH PARTICULAR DECLINE TOWARD THE END OF THE PRACTICE DURING THE FLOOR POSTURES. CONCLUSIONS: DBP DURING THE PRACTICE OF BIKRAM YOGA WAS SIGNIFICANTLY DIFFERENT FROM THAT PREVIOUSLY REPORTED FOR NONHEATED HATHA YOGA FOR NORMOTENSIVE SUBJECTS. FURTHER STUDIES EVALUATING THE SAME GROUP AT BOTH CONDITIONS ARE NEEDED TO BETTER CHARACTERIZE THE MAGNITUDE OF THE CHANGES IN HR, SBP, DBP, AND MOC.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
18 2386 34 YOGA AIDS BLOOD PRESSURE RECOVERY AFTER EXPOSURE OF FOREHEAD TO COLD: A PILOT STUDY. CONTEXT: HYPOTENSION THAT OCCURS AFTER A SINGLE BOUT OF AEROBIC EXERCISE ALSO ATTENUATES THE VASCULAR RESPONSE TO DISCRETE STRESSORS, AN EFFECT THAT CAN LAST FOR HOURS. IT IS UNKNOWN WHETHER THE HYPOTENSIVE BENEFITS OF TRADITIONAL EXERCISE EXTEND TO ALTERNATIVE FORMS OF MINDFUL EXERCISE, SUCH AS YOGA, TO CONFER TRANSIENT PROTECTION AGAINST NEUROVASCULAR CHALLENGES THAT INCREASE BLOOD PRESSURE (BP). OBJECTIVES: THE STUDY INTENDED TO EXAMINE THE EFFECTS OF ACUTE EXERCISE ON NEUROVASCULAR RESPONSES TO EXPOSURE OF THE FOREHEAD OF FEMALE YOGA PRACTITIONERS TO VASOCONSTRICTIVE COLD (IE, TO COLD PRESSOR STRESS). DESIGN: THE RESEARCH TEAM DESIGNED A STUDY WITH 3 CONDITIONS (IE, WITH PARTICIPANTS' PARTICIPATION IN 3 ACTIVITIES ON SEPARATE DAYS IN A REPEATED-MEASURES DESIGN). PARTICIPANTS WERE RANDOMLY ASSIGNED TO PERFORM THE ACTIVITIES IN 1 OF 3 ORDERS ACROSS SUCCESSIVE VISITS. PARTICIPANTS: PARTICIPANTS WERE 9 FEMALES, 20 TO 33 Y OLD, WHO HAD REGULARLY PRACTICED HATHA YOGA FROM 6 MO TO 12 Y BEFORE THE START OF THE STUDY. ALL PARTICIPANTS WERE NORMOTENSIVE AT ENTRY TO THE STUDY AND HAD NORMAL BODY WEIGHTS FOR THEIR HEIGHTS. INTERVENTIONS: ALL PARTICIPANTS PERFORMED 3 ACTIVITIES: (1) SELF-DIRECTED YOGA PRACTICE, THE INTERVENTION; (2) CYCLING EXERCISE AT A SELF-SELECTED INTENSITY, A POSITIVE CONTROL; AND (3) QUIET REST, A NEGATIVE CONTROL. OUTCOME MEASURES: POSTINTERVENTION, PARTICIPANTS' FOREHEADS WERE EXPOSED TO COLD. THEIR SYSTOLIC BLOOD PRESSURES (SBPS), DIASTOLIC BLOOD PRESSURES (DBPS), PULSE RATES, AND FOREARM OXYGENATION WERE ASSESSED USING NEAR-INFRARED SPECTROSCOPY. RESULTS: PARTICIPANTS' SBPS AND DBPS INCREASED DURING COLD PRESSOR STRESS UNDER ALL CONDITIONS, CONCURRENT WITH DECREASED FOREARM OXYGENATION. DURING RECOVERY FROM THE COLD, PARTICIPANTS' BPS DECLINED TO NEAR PRECOLD PRESSOR BASELINE LEVELS AFTER YOGA AND CYCLING BUT REMAINED ELEVATED AFTER QUIET REST. CONCLUSIONS: THE ENHANCED RECOVERY OF BP FROM COLD APPLIED TO THE FOREHEAD AFTER YOGA PRACTICE OR CYCLING EXERCISE SUGGESTS THAT BOTH TYPES OF EXERCISE PROMOTE A HYPOTENSIVE RESPONSE, WHICH COULD INDICATE LOWERED CARDIOVASCULAR RISK.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
19 1143 28 ELDERLY-CUSTOMIZED HATHA YOGA EFFECTS ON THE VASCULAR INFLAMMATION FACTORS OF ELDERLY WOMEN. [PURPOSE] THE AIM OF THIS STUDY WAS TO EXAMINE THE EFFECTS OF THE APPLICATION OF ELDERLY-CUSTOMIZED HATHA YOGA ON THE VASCULAR INFLAMMATION FACTORS OF ELDERLY WOMEN. [SUBJECTS AND METHODS] THIS RESEARCH WAS CONDUCTED WITH 14 ELDERLY WOMEN, BETWEEN 70 AND 80 YEARS OLD, DIVIDED INTO AN ELDERLY-CUSTOMIZED HATHA YOGA GROUP (N=7) AND A CONTROL GROUP (N=7). THE APPLICATION GROUP PARTICIPATED IN A HATHA YOGA PROGRAM DESIGNED TO BE ELDERLY-FRIENDLY FOR 10 WEEKS. AT THE END OF THE PROGRAM, THE VASCULAR INFLAMMATION FACTORS WERE MEASURED, INCLUDING THE ALBUMIN, WHITE BLOOD CELL COUNT, FIBRINOGEN, HIGH SENSITIVITY C-REACTIVE PROTEIN (HS-CRP), AND ERYTHROCYTE SEDIMENTATION RATE (ESR). [RESULTS] IN THE HATHA YOGA GROUP, THE ALBUMIN INCREASED SIGNIFICANTLY AFTER THE APPLICATION, WHEN COMPARED TO THE LEVEL BEFORE THE APPLICATION, WHILE THE FIBRINOGEN, HS-CRP, AND ESR DECREASED SIGNIFICANTLY. IN THE CONTROL GROUP, THE VASCULAR INFLAMMATION FACTOR LEVELS BEFORE AND AFTER THE APPLICATION PERIOD WERE NOT SIGNIFICANTLY DIFFERENT. [CONCLUSION] BASED ON THE RESULTS OF THIS STUDY, THE APPLICATION OF ELDERLY-CUSTOMIZED HATHA YOGA CREATED POSITIVE CHANGES IN THE VASCULAR INFLAMMATION FACTORS OF ELDERLY WOMEN.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
20 1012 32 EFFECTS OF ONE MONTH OF COMMON YOGA PROTOCOL PRACTICE APPEAR TO BE MEDIATED BY THE ANGIOGENIC AND NEUROGENIC PATHWAY: A PILOT STUDY. OBJECTIVE: TO EXAMINE THE MOLECULAR EFFECTS OF MINDFUL ACTIVITIES SUCH AS YOGA AND MEDITATION DESIGN: THIS WAS AN OPEN LABEL SINGLE ARM EXPLORATORY YOGA INTERVENTION STUDY. STUDY PARTICIPANTS: 64 HEALTHY INDIVIDUALS WITHIN THE AGE OF 18-60 YEARS WERE RECRUITED FOR THIS ONE MONTH YOGA INTERVENTION STUDY. INTERVENTION: COMMON YOGA PROTOCOL (CYP) IS A STANDARDIZED YOGA PROTOCOL RELEASED BY MINISTRY OF AYUSH, INDIA FOR INTERNATIONAL YOGA DAY. IT INCLUDES ALL ASPECTS OF YOGA I.E. ASANAS, PRANAYAMA AND MEDITATION. IT IS DESIGNED FOR ADOPTION BY ALL AGE GROUPS FOR THE HEALTH OF COMMUNITY. OUTCOME MEASURES: THE PARTICIPANTS WERE ASSESSED FOR BIOCHEMICAL PARAMETERS INCLUDING FASTING SUGAR AND LIPID PROFILE. THE MOLECULAR MARKERS OF NEUROGENESIS (I.E. BRAIN DERIVED NEUROTROPIC FACTOR, BDNF) AND ANGIOGENESIS (I.E. VASCULAR ENDOTHELIAL GROWTH FACTOR, VEGF AND ANGIOGENIN) ALONG WITH AMYLOID BETA (MARKER RELATED TO NEURO-DEGENERATIVE DISEASES) WERE ASSESSED. ALL THE ASSESSMENTS WERE MADE AT BASELINE AND AFTER ONE MONTH OF THE INTERVENTION. RESULTS: AFTER ONE MONTH OF CYP PRACTICE HIGH DENSITY LIPOPROTEIN (HDL) LEVELS INCREASED SIGNIFICANTLY (P<0.001), ALTHOUGH OTHER BIOCHEMICAL PARAMETERS I.E. FASTING SUGAR AND OTHER LIPID ASSESSMENTS WERE FOUND TO BE UNALTERED. ANGIOGENESIS MARKER, ANGIOGENIN WAS INCREASED SIGNIFICANTLY (P<0.002), OTHER ANGIOGENESIS MARKER VEGF DID NOT SHOW ANY CHANGE ALONG WITH BDNF, MARKER OF NEUROGENESIS. AMYLOID BETA LEVELS WERE ALSO UNALTERED. EVEN THOUGH INDIVIDUAL LEVELS OF VEGF AND AMYLOID BETA DID NOT SHOW ANY CHANGE, PROPORTION OF VEGF TO AMYLOID BETA SHOWED A SIGNIFICANT INCREASE (P<0.001) AFTER ONE MONTH OF CYP INTERVENTION INDICATING THAT THE CHANGE IN VEGF LEVELS WAS SIGNIFICANTLY HIGHER THAN THE CHANGE IN AMYLOID BETA LEVELS. CONCLUSION: CYP PRACTICE MAY INFLUENCE CELL SURVIVAL PATHWAYS MEDIATED BY ANGIOGENIC AND NEUROGENIC CROSS TALK. HENCE, CYP CAN BE CONSIDERED AS A PREVENTIVE MEASURE FOR DISEASES ASSOCIATED WITH IMPAIRED ANGIOGENIC AND NEUROGENIC MECHANISM. THIS IS THE FIRST STUDY TO EXAMINE THE EFFECTS OF CYP AT THE MOLECULAR LEVEL.	2021
