1  993 50 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
2  442 13 CEREBROVASCULAR DYNAMICS ASSOCIATED WITH YOGA BREATHING AND BREATH AWARENESS. AIMS: BREATH FREQUENCY CAN ALTER CEREBRAL BLOOD FLOW. THE STUDY AIMED TO DETERMINE BILATERAL MIDDLE CEREBRAL ARTERIAL HEMODYNAMICS IN HIGH-FREQUENCY YOGA BREATHING (HFYB) AND SLOW FREQUENCY ALTERNATE NOSTRIL YOGA BREATHING (ANYB) USING TRANSCRANIAL DOPPLER SONOGRAPHY. METHODS: HEALTHY MALE VOLUNTEERS WERE ASSESSED IN TWO SEPARATE TRIALS BEFORE, DURING, AND AFTER HFYB (2.0 HZ FOR 1 MIN, N = 16) AND ANYB (12 BREATHS PER MINUTE FOR 5 MIN, N = 22). HFYB AND ANYB WERE SEPARATELY COMPARED TO BREATH AWARENESS (BAW) AND TO CONTROL SESSIONS. STATISTICAL ANALYSIS: THE DATA WERE ANALYZED USING REPEATED-MEASURES ANOVA WITH BONFERRONI ADJUSTED POST HOC TESTS. RESULTS: DURING HFYB THERE WAS A DECREASE IN END-DIASTOLIC VELOCITY (EDV) AND MEAN FLOW VELOCITY (MFV) (P < 0.01 FOR LEFT AND P < 0.05 FOR RIGHT MIDDLE CEREBRAL ARTERIES; MCA) WITH AN INCREASE IN PULSATILITY INDEX (PI) FOR THE RIGHT MCA (P < 0.05). DURING ANYB, THERE WAS A BILATERAL DECREASE IN PEAK SYSTOLIC VELOCITY (P < 0.05 FOR LEFT AND P < 0.01 FOR RIGHT MCA), EDV (P < 0.01) AND MFV (P < 0.01 FOR LEFT AND P < 0.001 FOR RIGHT MCA) AND AN INCREASE IN PI (P < 0.01). DURING BAW OF THE TWO SESSIONS THERE WAS A DECREASE IN LATERALIZED FLOW AND END-DIASTOLIC VELOCITIES (P < 0.05) AND AN INCREASE IN PI (P < 0.05). CONCLUSIONS: CHANGES IN PEAK FLOW VELOCITIES AND PULSATILITY INDICES DURING AND AFTER HFYB, ANYB, AND BAW SUGGEST DECREASED CEREBROVASCULAR BLOOD FLOW AND INCREASED FLOW RESISTANCE BASED ON DIFFERENT MECHANISMS.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
3 2242 20 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. AN INDEPENDENT EFFECT OF PRACTICING YOGA COULD NOT BE DETECTED. STIFFNESS MEASURES WERE REPRODUCIBLE AND LEFT AND RIGHT SIDES WERE CONSISTENT WITH EACH OTHER.	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
4 1298 19 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
5  276 24 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
6 1045 36 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
7 1377 24 IMPACT OF HOT YOGA ON ARTERIAL STIFFNESS AND QUALITY OF LIFE IN NORMAL AND OVERWEIGHT/OBESE ADULTS. BACKGROUND: OBESITY IS ASSOCIATED WITH ARTERIAL STIFFENING AND DIMINISHED QUALITY OF LIFE. BIKRAM YOGA MAY BE A FEASIBLE ALTERNATIVE TO TRADITIONAL EXERCISE AMONG OBESE INDIVIDUALS. ACCORDINGLY, THE PURPOSE OF THIS STUDY WAS TO INVESTIGATE THE IMPACT OF BIKRAM YOGA, A HEATED STYLE OF HATHA YOGA, ON ARTERIAL STIFFNESS IN NORMAL AND OVERWEIGHT/OBESE ADULTS. METHODS: FORTY-THREE (23 NORMAL BODY MASS INDEX OR BMI; 20 OVERWEIGHT/OBESE) APPARENTLY HEALTHY PARTICIPANTS COMPLETED AN 8-WEEK BIKRAM YOGA INTERVENTION. BODY COMPOSITION WAS ESTIMATED VIA DUAL ENERGY X-RAY ABSORPTIOMETRY, ARTERIAL STIFFNESS WAS MEASURED VIA BRACHIALANKLE PULSE WAVE VELOCITY, AND HEALTH-RELATED QUALITY OF LIFE WAS ASSESSED VIA RAND 36-ITEM SHORT FORM SURVEY AT BASELINE AND AT THE END OF THE 8-WEEK INTERVENTION. RESULTS: AFTER THE INTERVENTION, BRACHIAL-ANKLE PULSE WAVE VELOCITY DECREASED (P < .05) IN OVERWEIGHT/OBESE PARTICIPANTS WHILE NO SUCH CHANGES WERE OBSERVED IN NORMAL BMI PARTICIPANTS. IN THE QUALITY OF LIFE MEASURES, EMOTIONAL WELL-BEING IMPROVED (P < .05) IN BOTH GROUPS, AND GENERAL HEALTH IMPROVED (P < .05) ONLY IN THE NORMAL WEIGHT BMI GROUP. CONCLUSION: BIKRAM YOGA AMELIORATES ARTERIAL STIFFNESS IN OVERWEIGHT/OBESE ADULTS AND CAN POSITIVELY IMPACT QUALITY OF LIFE REGARDLESS OF BMI.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
8  510 16 COMPARATIVE IMPACTS OF TAI CHI, BALANCE TRAINING, AND A SPECIALLY-DESIGNED YOGA PROGRAM ON BALANCE IN OLDER FALLERS. OBJECTIVE: TO COMPARE THE EFFECT OF A CUSTOM-DESIGNED YOGA PROGRAM WITH 2 OTHER BALANCE TRAINING PROGRAMS. DESIGN: RANDOMIZED CONTROLLED TRIAL. SETTING: RESEARCH LABORATORY. PARTICIPANTS: A GROUP OF OLDER ADULTS (N=39; MEAN AGE, 74.15 +/- 6.99 Y) WITH A HISTORY OF FALLING. INTERVENTIONS: THREE DIFFERENT EXERCISE INTERVENTIONS (TAI CHI, STANDARD BALANCE TRAINING, YOGA) WERE GIVEN FOR 12 WEEKS. MAIN OUTCOME MEASURES: BALANCE PERFORMANCE WAS EXAMINED DURING PRE- AND POSTTEST USING FIELD TESTS, INCLUDING THE 8-FOOT UP-AND-GO TEST, 1-LEG STANCE, FUNCTIONAL REACH, AND USUAL AND MAXIMAL WALKING SPEED. THE STATIC AND DYNAMIC BALANCES WERE ALSO ASSESSED BY POSTURAL SWAY AND DYNAMIC POSTUROGRAPHY, RESPECTIVELY. RESULTS: TRAINING PRODUCED SIGNIFICANT IMPROVEMENTS IN ALL FIELD TESTS (P<.005), BUT GROUP DIFFERENCE AND TIME X GROUP INTERACTION WERE NOT DETECTED. FOR POSTURAL SWAY, SIGNIFICANT DECREASES IN THE AREA OF THE CENTER OF PRESSURE WITH EYES OPEN (P=.001) AND EYES CLOSED (P=.002) WERE DETECTED AFTER TRAINING. FOR EYES OPEN, MAXIMUM MEDIAL-LATERAL VELOCITY SIGNIFICANTLY DECREASED FOR THE SAMPLE (P=.013). FOR EYES CLOSED, MEDIAL-LATERAL DISPLACEMENT DECREASED FOR TAI CHI (P<.01). FOR DYNAMIC POSTUROGRAPHY, SIGNIFICANT IMPROVEMENTS IN OVERALL SCORE (P=.001), TIME ON THE TEST (P=.006), AND 2 LINEAR MEASURES IN LATERAL (P=.001) AND ANTERIOR-POSTERIOR (P<.001) DIRECTIONS WERE SEEN FOR THE SAMPLE. CONCLUSIONS: YOGA WAS AS EFFECTIVE AS TAI CHI AND STANDARD BALANCE TRAINING FOR IMPROVING POSTURAL STABILITY AND MAY OFFER AN ALTERNATIVE TO MORE TRADITIONAL PROGRAMS.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
9  781 13 EFFECT OF YOGA ASANAS ON NERVE CONDUCTION IN TYPE 2 DIABETES. TWENTY TYPE 2 DIABETIC SUBJECTS BETWEEN THE AGE GROUP OF 30-60 YEARS WERE STUDIED TO SEE THE EFFECT OF 40 DAYS OF YOGA ASANAS ON THE NERVE CONDUCTION VELOCITY. THE DURATION OF DIABETES RANGED FROM 0-10 YEARS. SUBJECT SUFFERING FROM CARDIAC, RENAL AND PROLIFERATIVE RETINAL COMPLICATIONS WERE EXCLUDED FROM THE STUDY YOGA ASANAS INCLUDED SURYANAMSKAR. TADASAN, KONASAN, PADMASAN PRANAYAM, PASCHIMOTTANSAN ARDHMATSYENDRASAN, SHAVASAN, PAVANMUKTHASAN, SARPASAN AND SHAVASAN. SUBJECTS WERE CALLED TO THE CARDIO-RESPIRATORY LABORATORY IN THE MORNING TIME AND WERE GIVEN TRAINING BY THE YOGA EXPERT. THE YOGA EXERCISES WERE PERFORMED FOR 30-40 MINUTES EVERY DAY FOR 40 DAYS IN THE ABOVE SEQUENCE. THE SUBJECTS WERE PRESCRIBED CERTAIN MEDICINES AND DIET. THE BASAL BLOOD GLUCOSE, NERVE CONDUCTION VELOCITY OF THE MEDIAN NERVE WAS MEASURED AND REPEATED AFTER 40 DAYS OF YOGIC REGIME. ANOTHER GROUP OF 20 TYPE 2 DIABETES SUBJECTS OF COMPARABLE AGE AND SEVERITY, CALLED THE CONTROL GROUP, WERE KEPT ON PRESCRIBED MEDICATION AND LIGHT PHYSICAL EXERCISES LIKE WALKING. THEIR BASAL & POST 40 DAYS PARAMETERS WERE RECORDED FOR COMPARISON. RIGHT HAND AND LEFT HAND MEDIAN NERVE CONDUCTION VELOCITY INCREASED FROM 52.81 +/- 1.1 M/SEC TO 53.87 +/- 1.1 M/SEC AND 52.46 +/- 1.0 TO 54.75 +/- 1/1 M/SEC RESPECTIVELY. CONTROL GROUP NERVE FUNCTION PARAMETERS DETERIORATED OVER THE PERIOD OF STUDY, INDICATING THAT DIABETES IS A SLOWLY PROGRESSIVE DISEASE INVOLVING THE NERVES. YOGA ASANAS HAVE A BENEFICIAL EFFECT ON GLYCAEMIC CONTROL AND IMPROVE NERVE FUNCTION IN MILD TO MODERATE TYPE 2 DIABETES WITH SUB-CLINICAL NEUROPATHY.	2002	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
10 2076 22 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
11 2043 19 THE ACUTE EFFECTS OF VINYASA FLOW YOGA ON VASCULAR FUNCTION, LIPID AND GLUCOSE CONCENTRATIONS, AND MOOD. WHILE THE CHRONIC EFFECTS OF CERTAIN STYLES OF YOGA ON CARDIOMETABOLIC FACTORS HAVE BEEN INVESTIGATED, LITTLE IS KNOWN ABOUT THE ACUTE EFFECTS OF A SINGLE YOGA SESSION ON THESE OUTCOMES. MOREOVER, VINYASA YOGA'S POTENTIAL TO MODULATE CARDIOMETABOLIC OUTCOMES HAS NOT BEEN ESTABLISHED. THE PURPOSE OF THIS STUDY IS TO DETERMINE THE ACUTE EFFECTS OF A VINYASA YOGA SESSION ON ARTERIAL STIFFNESS, WAVE REFLECTION, LIPID AND GLUCOSE CONCENTRATIONS, AND MOOD IN ADULTS WITH PRIOR YOGA EXPERIENCE. THIRTY YOGA PRACTITIONERS WITH A MINIMUM OF 3 MONTHS OF PRACTICE EXPERIENCE WERE ENROLLED INTO THE STUDY. CAROTID-FEMORAL PULSE WAVE VELOCITY (CF-PWV), AUGMENTATION INDEX (AIX), LIPID PROFILE, GLUCOSE CONCENTRATIONS, AND MOOD (POSITIVE AND NEGATIVE AFFECT SCALE) WERE ASSESSED AT BASELINE AND IMMEDIATELY FOLLOWING A 1 -H VINYASA YOGA SESSION. AFTER THE YOGA SESSION, PARTICIPANTS HAD SIGNIFICANTLY LOWER AIX (P < 0.001), NON-HDL CHOLESTEROL (P < 0.05), AND NEGATIVE AFFECT (P < 0.01) COMPARED TO BASELINE. THESE RESULTS HIGHLIGHT THE EFFICACY OF A SINGLE BOUT OF YOGA IN ALTERING WAVE REFLECTION WHILE IMPROVING MOOD AND LIPID CONCENTRATIONS IN HEALTHY ADULTS WITH A HISTORY OF YOGA PRACTICE.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
12  860 17 EFFECT OF YOGA PRACTICE ON REDUCING COGNITIVE-MOTOR INTERFERENCE FOR IMPROVING DYNAMIC BALANCE CONTROL IN HEALTHY ADULTS. OBJECTIVE: THE PURPOSE OF OUR STUDY WAS TO INVESTIGATE THE EFFECTS OF YOGA ON REDUCING COGNITIVE-MOTOR INTERFERENCE (CMI) FOR MAINTAINING BALANCE CONTROL DURING VARIED BALANCE TASKS. METHOD: YOGA (N=10) AND AGE-SIMILAR NON-PRACTITIONERS (N=10) PERFORMED THREE BALANCE TASKS INCLUDING THE LIMITS OF STABILITY TEST (LOS - INTENTIONAL BALANCE), MOTOR CONTROL TEST (MCT - REACTIVE BALANCE), AND SENSORY ORGANIZATION TEST (SOT -CONDITION 6: INDUCING BOTH SOMATOSENSORY AND VISUAL CONFLICTS) UNDER SINGLE-TASK (ST) AND DUAL-TASK (DT, ADDITION OF A COGNITIVE WORKING MEMORY TASK) CONDITIONS. THE MOTOR PERFORMANCE WAS ASSESSED BY RECORDING THE RESPONSE TIME (RT) AND MOVEMENT VELOCITY (MV) OF THE CENTER OF PRESSURE (COP) ON LOS TEST, WEIGHT SYMMETRY (WS) OF COP ON THE MCT TEST AND EQUILIBRIUM (EQ) OF COP ON THE SOT TEST. COGNITIVE PERFORMANCE WAS RECORDED AS THE NUMBER OF CORRECT RESPONSES ENUMERATED IN SITTING (ST) AND UNDER DT CONDITIONS. THE MOTOR COST (MC) AND COGNITIVE COST (CC) WERE COMPUTED USING THE FORMULA ([ST-DT]/ST)*100 FOR ALL THE VARIABLES. GREATER COST INDICATES LOWER PERFORMANCE UNDER DT VERSUS ST CONDITION. RESULTS: THE YOGA GROUP SHOWED A SIGNIFICANTLY LESSER MC FOR BOTH MCT AND SOT TESTS (P<0.05) IN COMPARISON TO THEIR COUNTERPARTS. THE CC WERE SIGNIFICANTLY LOWER ON LOS AND MCT TEST FOR THE YOGA GROUP (P<0.05). CONCLUSION: RESULTS SUGGEST THAT YOGA PRACTICE CAN SIGNIFICANTLY REDUCE CMI BY IMPROVING ALLOCATION AND UTILIZATION OF ATTENTIONAL RESOURCES FOR BOTH BALANCE CONTROL AND EXECUTIVE COGNITIVE FUNCTIONING; THUS RESULTING IN BETTER PERFORMANCE UNDER DT CONDITIONS.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
13 2075 26 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
14  341 25 ARTERIAL BLOOD PRESSURE AND CARDIOVASCULAR RESPONSES TO YOGA PRACTICE. CONTEXT: YOGA IS QUALITATIVELY DIFFERENT FROM ANY OTHER MODE OF PHYSICAL ACTIVITY IN THAT IT CONSISTS OF A UNIQUE COMBINATION OF ISOMETRIC MUSCULAR CONTRACTIONS, STRETCHING EXERCISES, RELAXATION TECHNIQUES, AND BREATHING EXERCISES. IN PARTICULAR, YOGA POSTURES CONSIST OF SYSTEMIC ISOMETRIC CONTRACTIONS THAT ARE KNOWN TO ELICIT MARKED INCREASES IN MEAN BLOOD PRESSURE THAT ARE NOT OBSERVED DURING DYNAMIC EXERCISE. STRETCHING CAN ALSO INDUCE INCREASES IN BLOOD PRESSURE AND SYMPATHETIC NERVE ACTIVITY IN THE MUSCLES. CURRENTLY, NOT MUCH IS KNOWN ABOUT CHANGES IN BLOOD PRESSURE AND OTHER CARDIOVASCULAR RESPONSES TO YOGA PRACTICE. OBJECTIVE: THE STUDY INTENDED TO DETERMINE THE ACUTE EFFECTS OF ONE SESSION OF HATHA YOGA PRACTICE ON BLOOD PRESSURE AND OTHER CARDIOVASCULAR RESPONSES. TO GAIN INSIGHT INTO THE LONG-TERM EFFECTS OF YOGA PRACTICE, BOTH NOVICE (N = 19) AND ADVANCED (N = 18) YOGA PRACTITIONERS WERE STUDIED. DESIGN: THE TWO GROUPS WERE MATCHED FOR AGE, GENDER, BMI, AND BLOOD PRESSURE. SETTING: THE SETTING WAS A RESEARCH LABORATORY AT A UNIVERSITY. PARTICIPANTS: THIRTY-SIX APPARENTLY HEALTHY, NONOBESE, SEDENTARY, OR RECREATIONALLY ACTIVE INDIVIDUALS FROM THE COMMUNITY PARTICIPATED IN THE STUDY. INTERVENTION THE INTERVENTION COMPRISED ONE SESSION OF YOGA PRACTICE, IN WHICH PARTICIPANTS FOLLOWED A CUSTOM MADE INSTRUCTIONAL VIDEO PROVIDING A YOGA ROUTINE THAT CONSISTED OF A SERIES OF 23 HATHA-BASED YOGA POSTURES. OUTCOME MEASURES: PRIOR TO ARRIVING AT THE LABORATORY, EACH PARTICIPANT COMPLETED A RESEARCH HEALTH QUESTIONNAIRE, A TRAINING-STATUS QUESTIONNAIRE, AND A YOGA-EXPERIENCE QUESTIONNAIRE. PRIOR TO THE YOGA PRACTICE, EACH PARTICIPANT'S HEIGHT, BODY FAT PERCENTAGE, TRUNK OR LUMBAR FLEXIBILITY, AND ARTERIAL STIFFNESS AS ASSESSED BY CAROTID FEMORAL PULSE WAVE VELOCITY (CFPWV) WERE MEASURED. FOR EACH POSTURE DURING THE YOGA PRACTICE, THE STUDY CONTINUOUSLY MEASURED SYSTOLIC, MEAN, AND DIASTOLIC BLOOD PRESSURES, HEART RATE, STROKE VOLUME, AND CARDIAC OUTPUT. RESULTS: SYSTOLIC, MEAN, AND DIASTOLIC BLOOD PRESSURES INCREASED SIGNIFICANTLY DURING THE YOGA PRACTICE. THE MAGNITUDE OF THESE INCREASES IN BLOOD PRESSURE WAS GREATEST WITH STANDING POSTURES. HEART RATE AND CARDIAC OUTPUT INCREASED SIGNIFICANTLY DURING YOGA PRACTICE, ESPECIALLY WITH STANDING POSTURES. OVERALL, NO DIFFERENCES EXISTED IN CARDIOVASCULAR RESPONSES BETWEEN THE NOVICE AND ADVANCED PRACTITIONERS THROUGHOUT THE YOGA TESTING SESSION; CFPWV VELOCITY WAS SIGNIFICANTLY AND INVERSELY ASSOCIATED WITH LUMBAR FLEXION BUT NOT WITH SIT-AND-REACH TEST SCORES. CONCLUSIONS: THE RESEARCH TEAM CONCLUDED THAT A VARIETY OF HATHA YOGA POSTURES, ESPECIALLY STANDING POSTURES, EVOKED SIGNIFICANT INCREASES IN BLOOD PRESSURE. THE ELEVATION IN BLOOD PRESSURE DUE TO YOGA PRACTICE WAS ASSOCIATED WITH INCREASES IN CARDIAC OUTPUT AND HEART RATE, WHICH ARE RESPONSES SIMILAR TO THOSE OBSERVED IN ISOMETRIC EXERCISE. THE LACK OF OBVIOUS DIFFERENCES IN BLOOD PRESSURE AND OTHER CARDIOVASCULAR RESPONSES BETWEEN NOVICE AND ADVANCED YOGA PRACTITIONERS SUGGESTS THAT LONG-TERM YOGA PRACTICE DOES NOT ATTENUATE ACUTE YOGA RESPONSES.	2013	

15 2072 16 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
16  443 13 CERVICAL ARTERIAL DISSECTION AND TRAUMATIC MYELOPATHY FOLLOWING YOGA: SURGICAL CASE REPORT. INTRODUCTION: CERVICAL SPONDYLOSIS CAN PREDISPOSE PATIENTS TO CENTRAL CANAL STENOSIS. IN THIS SETTING, MYELOPATHY THROUGH FURTHER FLATTENING OF THE CORD FROM EXTRINSIC COMPRESSION CAN BE PRECIPITATED BY RELATIVELY MINOR TRAUMAS. ARTERIAL DISSECTION IS SIMILARLY CONSIDERED A RESULT OF HIGH VELOCITY OR MOMENTUM DURING TRAUMA, COMMONLY ASSOCIATED WITH FRACTURES, CERVICAL HYPERFLEXION, OR DIRECT BLUNT FORCE TO THE NECK. OVERALL, PRECAUTIONS FOR BOTH ARTERIAL DISSECTION AND MYELOPATHY ARE RARELY CONSIDERED IN LOW-VELOCITY, STATIC ACTIVITIES SUCH AS YOGA. CASE PRESENTATION: THE AUTHORS REPORT THE CASE OF A 63-YEAR-OLD MAN WHO SUFFERED CONCURRENT CERVICAL MYELOPATHY FROM MULTILEVEL SPONDYLOPATHY, RIGHT VERTEBRAL ARTERY DISSECTION, AND LEFT CERVICAL CAROTID ARTERY DISSECTION FOLLOWING A YOGA SESSION. SYMPTOMATOLOGY CONSISTED OF ACUTE ONSET NECK PAIN, UPPER EXTREMITY SENSORY PARESTHESIA, WORSENING GAIT AND BALANCE, AND IMPAIRED DEXTERITY FOR SEVERAL WEEKS. CERVICAL MRI WAS OBTAINED GIVEN MYELOPATHIC SYMPTOMS AND REVEALED SPONDYLOSIS WITH COMPRESSION AND T2 SIGNAL CHANGE AT C3-C4. CT ANGIOGRAPHY OF THE NECK REVEALED AFOREMENTIONED DISSECTIONS WITHOUT FLOW LIMITING STENOSIS OR OCCLUSION. A THERAPEUTIC HEPARIN INFUSION WAS STARTED PREOPERATIVELY UNTIL THE PATIENT UNDERWENT C3-C4 ANTERIOR CERVICAL DISCECTOMY AND FUSION. ASPIRIN AND PLAVIX WERE THEN STARTED WITHOUT INCIDENCE AND THE PATIENT HAD SIGNIFICANT BUT GRADUAL IMPROVEMENT IN MYELOPATHIC SYMPTOMS AT 6-WEEK FOLLOW-UP. DISCUSSION: THE STATIC YET INTENSIVE POSES ASSOCIATED WITH YOGA PRESENT A RARE ETIOLOGY FOR ARTERIAL DISSECTION AND MYELOPATHY, BUT PATIENTS WITH PERSISTENT AND PROGRESSIVE SYMPTOMS SHOULD BE SCREENED WITH THE APPROPRIATE IMAGING MODALITY. CERVICAL DECOMPRESSION SHOULD BE EXPEDITED BEFORE INITIATING AN ANTIPLATELET MEDICATION.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
17  553 15 CORRELATION OF HEART RATE VARIABILITY WITH CAROTID INTIMA MEDIA THICKNESS AFTER 6 MONTH OF YOGA INTERVENTION IN PREDIABETICS. INTRODUCTION: ATHEROSCLEROTIC CAROTID INTIMAMEDIA THICKNESS (CIMT) MAY BE ASSOCIATED WITH ALTERATIONS IN THE AUTONOMIC FUNCTIONS. THE AIM OF THIS STUDY WAS TO INVESTIGATE THE EFFECT OF 6-MONTH YOGA INTERVENTION ON HEART RATE VARIABILITY (HRV) AND CIMT IN ELDERLY SUBJECTS AND THE CORRELATION BETWEEN HRV AND CIMT. METHODOLOGY: THIS WAS A RANDOMIZED CONTROLLED STUDY, IN WHICH A TOTAL OF 250 SUBJECTS WERE ENROLLED. RANDOMIZATION AND ALLOCATION IN YOGA AND CONTROL GROUPS WERE PERFORMED USING COMPUTER-GENERATED RANDOM NUMBERS. THE CIMT WAS DETERMINED BY B-MODE ULTRASONOGRAPHY, AND CARDIAC AUTONOMIC FUNCTION WAS DETERMINED THROUGH FREQUENCY DOMAIN PARAMETER OF HRV MEASURES AT BASELINE AND AFTER 6 MONTHS OF YOGA INTERVENTION. RESULTS: PARTICIPANTS HAD A MEAN AGE OF 45.4 +/- 6.4 YEARS, AND A MEAN CIMT IN CONTROL (0.70 +/- 0.05) AND STUDY GROUP (0.69 +/- 0.073), AND LOW FREQUENCY/HIGH FREQUENCY (LF/HF) RATIO IN CONTROL (2.20 +/- 1.05) AND STUDY GROUP (0.57 +/- 0.54). YOGA GROUP HAD EVIDENCE OF INCREASED VAGAL ACTIVITY IN THE FREQUENCY DOMAIN (HF AND LF/HF RATIO, P < 0.001) WITH RESPECT TO CONTROL GROUP. MOREOVER, A STUDY GROUP SHOWED LOWER INTIMAMEDIA THICKNESS (IMT) THAN CONTROL SUBJECTS (P < 0.01). IN THE WHOLE POPULATION, LF/HF RATIO POSITIVELY AND SIGNIFICANTLY CORRELATED (R = 0.665, P < 0.01) TO IMT. CONCLUSION: THIS STUDY DEMONSTRATED THAT, AFTER YOGA INTERVENTION, LF/HF RATIO IS POSITIVELY CORRELATED WITH CIMT, A PUTATIVE INDEX OF ATHEROSCLEROSIS, CONFIRMING CARDIAC AUTONOMIC NEUROPATHY AS A PART OF THE PATHOPHYSIOLOGICAL PATHWAY FOR ATHEROSCLEROSIS. IT CONFIRMS THAT THE REGULAR YOGA REPRESENTS A VALUABLE STRATEGY TO COUNTER IMPAIRMENTS OF CARDIAC AUTONOMIC ACTIVITY AND ARTERY STRUCTURAL CHANGES.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
18  967 20 EFFECTS OF AEROBIC EXERCISE TRAINING AND YOGA ON THE BAROREFLEX IN HEALTHY ELDERLY PERSONS. IT IS UNCLEAR WHETHER THE AGE-ASSOCIATED REDUCTION IN BAROREFLEX SENSITIVITY IS MODIFIABLE BY EXERCISE TRAINING. THE EFFECTS OF AEROBIC EXERCISE TRAINING AND YOGA, A NON-AEROBIC CONTROL INTERVENTION, ON THE BAROREFLEX OF ELDERLY PERSONS WAS DETERMINED. BAROREFLEX SENSITIVITY WAS QUANTIFIED BY THE ALPHA-INDEX, AT HIGH FREQUENCY (HF; 0.15-0.35 HZ, REFLECTING PARASYMPATHETIC ACTIVITY) AND MID-FREQUENCY (MF; 0.05-0.15 HZ, REFLECTING SYMPATHETIC ACTIVITY AS WELL), DERIVED FROM SPECTRAL AND CROSS-SPECTRAL ANALYSIS OF SPONTANEOUS FLUCTUATIONS IN HEART RATE AND BLOOD PRESSURE. TWENTY-SIX (10 WOMEN) SEDENTARY, HEALTHY, NORMOTENSIVE ELDERLY (MEAN 68 YEARS, RANGE 62-81 YEARS) SUBJECTS WERE STUDIED. FOURTEEN (4 WOMEN) OF THE SEDENTARY ELDERLY SUBJECTS COMPLETED 6 WEEKS OF AEROBIC TRAINING, WHILE THE OTHER 12 (6 WOMEN) SUBJECTS COMPLETED 6 WEEKS OF YOGA. HEART RATE DECREASED FOLLOWING YOGA (69 +/- 8 VS. 61 +/- 7 MIN-1, P < 0.05) BUT NOT AEROBIC TRAINING (66 +/- 8 VS. 63 +/- 9 MIN-1, P = 0.29). VO2 MAX INCREASED BY 11% FOLLOWING YOGA (P < 0.01) AND BY 24% FOLLOWING AEROBIC TRAINING (P < 0.01). NO SIGNIFICANT CHANGE IN ALPHA MF (6.5 +/- 3.5 VS. 6.2 +/- 3.0 MS MMHG-1, P = 0.69) OR ALPHA HF (8.5 +/- 4.7 VS. 8.9 +/- 3.5 MS MMHG-1, P = 0.65) OCCURRED AFTER AEROBIC TRAINING. FOLLOWING YOGA, ALPHA HF (8.0 +/- 3.6 VS. 11.5 +/- 5.2 MS MMHG-1, P < 0.01) BUT NOT ALPHA MF (6.5 +/- 3.0 VS. 7.6 +/- 2.8 MS MMHG-1, P = 0.29) INCREASED. SHORT-DURATION AEROBIC TRAINING DOES NOT MODIFY THE ALPHA-INDEX AT ALPHA MF OR ALPHA HF IN HEALTHY NORMOTENSIVE ELDERLY SUBJECTS. ALPHA HF BUT NOT ALPHA MF INCREASED FOLLOWING YOGA, SUGGESTING THAT THESE PARAMETERS ARE MEASURING DISTINCT ASPECTS OF THE BAROREFLEX THAT ARE SEPARATELY MODIFIABLE.	1997	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
19  411 14 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
20  808 22 EFFECT OF YOGA ON ARTERIAL STIFFNESS IN ELDERLY SUBJECTS WITH INCREASED PULSE PRESSURE: A RANDOMIZED CONTROLLED STUDY. OBJECTIVE: WE AIMED TO DETERMINE THE EFFECT OF YOGA ON ARTERIAL FUNCTION IN ELDERLY WITH INCREASED PULSE PRESSURE (PP). DESIGN: RANDOMIZED CONTROLLED STUDY WITH TWO PARALLEL GROUPS. PARTICIPANTS: ELDERLY SUBJECTS WITH PP>/=60 MMHG (N=60). INTERVENTIONS: YOGA GROUP (N=30) WAS ASSIGNED FOR YOGA TRAINING AND BRISK-WALKING (BW) GROUP (N=30) FOR BRISK-WALK WITH STRETCHING EXERCISE FOR 1H IN THE MORNING FOR 6 DAYS IN A WEEK FOR 12 WEEKS. MAIN OUTCOME MEASURES: ARTERIAL STIFFNESS MEASURES: BRACHIAL-ANKLE PULSE WAVE VELOCITY (BAPWV), CAROTID-FEMORAL PULSE WAVE VELOCITY (C-F PWV), AORTIC AUGMENTATION INDEX (AIX@75), ARTERIAL STIFFNESS INDEX AT BRACHIAL (BASI) AND TIBIAL ARTERIES (AASI). TOTAL SERUM NITRIC OXIDE CONCENTRATION (NOX) AS AN INDEX OF ENDOTHELIAL FUNCTION. HEART RATE VARIABILITY (HRV) MEASURES: LOW FREQUENCY AND HIGH FREQUENCY IN NORMALIZED UNITS (LFNU, HFNU) AND LF/HF RATIO. RESULTS: THE MEAN BETWEEN-GROUP CHANGE (WITH 95% CI) IN ARTERIAL STIFFNESS: C-F PWV(M/S) [1.25(0.59-1.89); P<0.001], BAPWV(M/S) [1.96(0.76-3.16), P<0.01], AIX@75 [3.07(0.24-5.89), P=0.066], AASI [8.3(4.06-12.53), P<0.001]; ENDOTHELIAL FUNCTION INDEX: NO(MUMOL/L) [-9.03(-14.57 TO -3.47), P<0.001]; SBP(MMHG) [14.23(12.03-16.44), P<0.001], DBP(MMHG) [0.1(-1.95-2.15), P=0.38], PP(MMHG) [14.07(11.2-16.92), P<0.001], MAP(MMHG) [4.7(3.08-6.32), P<0.001]; AND CARDIAC AUTONOMIC FUNCTION: LF(NU) [4.81(1.54-8.08), P<0.01], HF(NU) [-4.13(-7.57 TO -0.69), P<0.01], LF/HF RATIO [0.84(0.3-1.37), P<0.001], INDICATE SIGNIFICANT DIFFERENCE IN EFFECTS OF TWO INTERVENTION ON ARTERIAL STIFFNESS, ENDOTHELIAL FUNCTION, BP AND CARDIAC AUTONOMIC ACTIVITY. THERE WAS SIGNIFICANT CHANGE WITHIN-YOGA GROUP IN VASCULAR FUNCTION, BP AND AUTONOMIC FUNCTION, WHILE NO SIGNIFICANT CHANGE WITHIN-BW GROUP WAS OBSERVED. CONCLUSION: OUR FINDINGS SUGGEST THAT YOGA PROGRAM OFFERED WAS MORE EFFECTIVE THAN BRISK-WALK IN REDUCING ARTERIAL STIFFNESS ALONG WITH BP IN ELDERLY INDIVIDUALS WITH INCREASED PP. YOGA CAN ALSO SIGNIFICANTLY REDUCE SYMPATHETIC ACTIVITY AND IMPROVE ENDOTHELIAL FUNCTION WITH ENHANCEMENT IN BIOAVAILABILITY OF NO.	2015
