1  276 180 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	
                                                                               
2 1889  52 REGULAR YOGA PRACTICE IMPROVES ANTIOXIDANT STATUS, IMMUNE FUNCTION, AND STRESS HORMONE RELEASES IN YOUNG HEALTHY PEOPLE: A RANDOMIZED, DOUBLE-BLIND, CONTROLLED PILOT STUDY. OBJECTIVE: THE AIM OF THE PRESENT STUDY IS TO HIGHLIGHT THE BENEFICIAL EFFECTS OF YOGA PRACTICE ON BIO-PARAMETERS, SUCH AS OXIDATIVE STRESS, ANTIOXIDANT COMPONENTS, IMMUNE FUNCTIONS, AND SECRETION OF STRESS HORMONES, IN HEALTHY YOUNG PEOPLE. STUDY DESIGN: THIS STUDY WAS CONDUCTED ON HEALTHY VOLUNTEERS RECRUITED FROM AMONG UNIVERSITY STUDENTS, WHO WERE DIVIDED INTO TWO GROUPS: A CONTROL (NO YOGA INTERVENTION, N=13) GROUP AND A YOGA (N=12) GROUP. YOGA PRACTICE WAS WITH AN INSTRUCTOR FOR 90 MINUTES ONCE A WEEK SPREAD OVER 12 WEEKS, WITH RECOMMENDATIONS TO PRACTICE DAILY AT HOME FOR 40 MINUTES WITH THE HELP OF A DVD. THE YOGA PROGRAM CONSISTED OF YOGA BODY POSES (ASANAS), EXERCISES INVOLVING AWARENESS, VOLUNTARY REGULATION OF BREATH (PRANAYAMA), AND MEDITATIONAL PRACTICES. WHOLE BLOOD SAMPLES WERE COLLECTED WHEN THE VOLUNTEERS HAD FASTED FOR 8 HOURS AT 0 AND 12 WEEKS. THE OXIDATIVE STRESS/ANTIOXIDANT COMPONENTS, IMMUNE-RELATED CYTOKINES, AND STRESS HORMONES WERE EVALUATED IN SERUM OR PLASMA. RESULTS: SERUM LEVELS OF NITRIC OXIDE, F2-ISOPROSTANE, AND LIPID PEROXIDE WERE SIGNIFICANTLY DECREASED BY YOGA PRACTICE (P<0.05 OR P=0.01), WHEREAS SERUM TOTAL GLUTATHIONE (GSH) CONTENTS, ACTIVITIES OF GSH-PEROXIDASE, AND GSH-S-TRANSFERASE WERE REMARKABLY INCREASED AFTER YOGA PRACTICE COMPARED WITH THE CONTROL GROUP (P<0.05 OR P=0.01). YOGA PRACTICE ALSO SIGNIFICANTLY INCREASED IMMUNE-RELATED CYTOKINES, SUCH AS INTERLEUKIN-12, AND INTERFERON-GAMMA, IN SERUM (P<0.05 OR P=0.01). YOGA PRACTICE SIGNIFICANTLY REDUCED THE PLASMA LEVELS OF ADRENALIN (P<0.05) AND INCREASED PLASMA LEVELS OF SEROTONIN COMPARED WITH THE CONTROL GROUP (P<0.05). CONCLUSIONS: REGULAR YOGA PRACTICE REMARKABLY ATTENUATED OXIDATIVE STRESS AND IMPROVED ANTIOXIDANT LEVELS OF THE BODY. MOREOVER, YOGA BENEFICIALLY AFFECTED STRESS HORMONE RELEASES AS WELL AS PARTIALLY IMPROVED IMMUNE FUNCTION.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
3  833  42 EFFECT OF YOGA ON OXIDATIVE STRESS IN ELDERLY WITH GRADE-I HYPERTENSION: A RANDOMIZED CONTROLLED STUDY. BACKGROUND AND OBJECTIVES: HYPERTENSION, ESPECIALLY IN ELDERLY IS A STRONG RISK FACTOR FOR CARDIOVASCULAR MORTALITY AND MORBIDITY. OXIDATIVE STRESS HAS BEEN IMPLICATED AS ONE OF THE UNDERLYING CAUSE OF HYPERTENSION. YOGA HAS BEEN FOUND TO CONTROL HYPERTENSION IN THE ELDERLY, BUT THE UNDERLYING BENEFITS OF MECHANISM IN RELATION TO OXIDATIVE STRESS REGULATION REMAINS UNCLEAR. THE PURPOSE OF THE STUDY WAS TO INVESTIGATE THE EFFECT OF YOGA ON OXIDATIVE STRESS IN ELDERLY WITH GRADE-I HYPERTENSION. METHODS: AN OPEN PARALLEL-ARM RANDOMISED CONTROLLED STUDY WAS CONDUCTED AT BLDE UNIVERSITY'S SHRI B.M.PATIL MEDICAL COLLEGE, HOSPITAL AND RESEARCH CENTRE, INDIA ON ELDERLY MALE INDIVIDUALS WITH GRADE-I HYPERTENSION (N=57, AGE 60-80 YEARS). STUDY (YOGA) GROUP WAS ASSIGNED FOR YOGA INTERVENTION AND CONTROL GROUP FOR WALKING FOR ONE HOUR IN THE MORNING FOR SIX DAYS IN A WEEK FOR THREE MONTHS UNDER THE SUPERVISION OF YOGA INSTRUCTOR AND PHYSICAL TRAINING INSTRUCTOR RESPECTIVELY. SERUM MALONDIALDEHYDE (MDA) AS AN INDICATOR OF OXIDATIVE STRESS AND ANTIOXIDANTS SUCH AS SERUM SUPEROXIDE DISMUTASE (SOD), REDUCED GLUTATHIONE (GSH) AND VITAMIN C LEVELS WERE ESTIMATED. RESULTS: YOGA PRACTICE FOR THREE MONTHS HAS SIGNIFICANTLY REDUCED SERUM MDA LEVEL (P<0.001), AND ENHANCED ANTIOXIDANTS LEVEL SUCH AS SOD ACTIVITY (P=0.007), SERUM GSH (P=0.002) AND VITAMIN C (P=0.002). IN THE CONTROL GROUP, WE OBSERVED A SIGNIFICANT INCREASE IN SERUM MDA LEVEL (P=0.04) AND REDUCTION IN SERUM VITAMIN C LEVEL (P=0.015) WITH NO SIGNIFICANT DIFFERENCE IN THE SOD ACTIVITY AND GSH LEVEL. CONCLUSION: THESE FINDINGS SUGGEST THAT YOGA IS AN EFFECTIVE MEANS TO REDUCE OXIDATIVE STRESS AND TO IMPROVE ANTIOXIDANT DEFENSE IN ELDERLY HYPERTENSIVE INDIVIDUALS.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
4 1298  33 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  986  31 EFFECTS OF HATHA YOGA EXERCISE ON PLASMA MALONDIALDEHYDE CONCENTRATION AND SUPEROXIDE DISMUTASE ACTIVITY IN FEMALE PATIENTS WITH SHOULDER PAIN. [PURPOSE] THE PURPOSE OF THIS STUDY WAS TO ANALYZE THE EFFECTS OF HATHA YOGA EXERCISE ON PLASMA MALONDIALDEHYDE (MDA) CONCENTRATION AND SUPEROXIDE DISMUTASE (SOD) ACTIVITY IN FEMALE PATIENTS WITH SHOULDER PAIN. [SUBJECTS] SUBJECTS COMPRISED 20 FEMALE PATIENTS WITH SHOULDER PAIN. [METHODS] SUBJECTS WERE DIVIDED INTO 2 GROUPS: A HATHA YOGA EXERCISE GROUP (N = 10) AND A CONTROL GROUP THAT PERFORMED NO EXERCISE (N = 10). THE SUBJECTS' BODY COMPOSITION, PLASMA MALONDIALDEHYDE CONCENTRATIONS, AND SUPEROXIDE DISMUTASE ACTIVITIES WERE MEASURED BEFORE AND AFTER A 16-WEEK HATHA YOGA EXERCISE PROGRAM. [RESULTS] AFTER THE 16-WEEK HATHA YOGA EXERCISE PROGRAM, THE EXERCISE GROUP HAD SIGNIFICANTLY LOWER PLASMA MDA CONCENTRATIONS THAN THE CONTROL GROUP. IN ADDITION, THE EXERCISE GROUP HAD SIGNIFICANTLY HIGHER PLASMA SOD ACTIVITY THAN THE CONTROL GROUP. [CONCLUSIONS] HATHA YOGA EXERCISE IMPROVES FLEXIBILITY, MUSCLE TONE AND STRENGTH, BALANCE, AND JOINT FUNCTION. OUR FINDINGS INDICATE THAT REGULAR AND CONTINUOUS YOGA EXERCISE EFFECTIVELY IMPROVED BODY COMPOSITION, DECREASE PLASMA MDA CONCENTRATION, AND INCREASE PLASMA SOD ACTIVITY IN FEMALE PATIENTS WITH SHOULDER PAIN.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
6  692  34 EFFECT OF COMMUNITY-BASED YOGA INTERVENTION ON OXIDATIVE STRESS AND GLYCEMIC PARAMETERS IN PREDIABETES: A RANDOMIZED CONTROLLED TRIAL. OBJECTIVES: TO STUDY THE EFFECTIVENESS OF YOGA INTERVENTION ON OXIDATIVE STRESS, GLYCEMIC STATUS, BLOOD PRESSURE AND ANTHROPOMETRY IN PREDIABETES. DESIGN: RANDOMIZED-CONTROLLED TRIAL. PARTICIPANTS: TWENTY NINE PREDIABETES SUBJECTS AGED 30-75 YEARS. SETTING: YOGA WAS CONDUCTED AT 4 DIFFERENT COMMUNITY DIABETES CLINICS IN MANGALORE, INDIA. INTERVENTIONS: PARTICIPANTS WERE RANDOMIZED TO EITHER 3-MONTH YOGA OR WAIT-LIST CONTROL GROUPS. MAIN OUTCOME MEASURES: MALONDIALDEHYDE, GLUTATHIONE, VITAMIN C, VITAMIN E, SUPEROXIDE DISMUTASE, PLASMA GLUCOSE, GLYCATED HAEMOGLOBIN, BMI, WAIST CIRCUMFERENCE, WAIST-TO-HIP RATIO AND BLOOD PRESSURE. RESULTS: YOGA INTERVENTION RESULTED IN A SIGNIFICANT DECLINE IN MALONDIALDEHYDE (P<0.001), RELATIVE TO THE CONTROL GROUP. IN COMPARISON WITH THE CONTROL, THERE WAS A SIGNIFICANT IMPROVEMENT IN BMI, WAIST CIRCUMFERENCE, SYSTOLIC BLOOD PRESSURE AND FASTING GLUCOSE LEVELS AT FOLLOW-UP. NO SIGNIFICANT IMPROVEMENT IN GLYCATED HAEMOGLOBIN, WAIST-TO-HIP RATIO OR ANY OF THE ANTIOXIDANTS WAS OBSERVED. CONCLUSIONS: YOGA INTERVENTION MAY BE HELPFUL IN CONTROL OF OXIDATIVE STRESS IN PREDIABETES SUBJECTS. YOGA CAN ALSO BE BENEFICIAL IN REDUCTION IN BMI, WAIST CIRCUMFERENCE, SYSTOLIC BLOOD PRESSURE AND FASTING GLUCOSE. EFFECT OF YOGA ON ANTIOXIDANT PARAMETERS WAS NOT EVIDENT IN THIS STUDY.

THE PRESENT RANDOMIZED CONTROLLED TRIAL (RCT) EVALUATED THE COMPARATIVE EFFICACY OF 12 WEEK YOGA-BASED LIFESTYLE INTERVENTION (YBLI) AND DIETARY INTERVENTION (DI) ALONE ON ADIPOKINES, INFLAMMATION, AND OXIDATIVE STRESS IN INDIAN ADULTS WITH METABOLIC SYNDROME (MET S). A PARALLEL, TWO ARM, RCT WAS CONDUCTED IN INTEGRAL HEALTH CLINIC (IHC), ALL INDIA INSTITUTE OF MEDICAL SCIENCES, INDIA FROM 2012 TO 2014. IHC IS AN OUTPATIENT FACILITY CONDUCTING YBLI PROGRAMS FOR PREVENTION AND MANAGEMENT OF CHRONIC DISEASES. TWO HUNDRED SIXTY MEN AND WOMEN (20-45 YEARS) VISITING THE OUTPATIENT DEPARTMENT OF A TERTIARY CARE HOSPITAL WERE DIAGNOSED WITH MET S AND RANDOMIZED 1:1 TO RECEIVE 12 WEEK YBLI (N = 130) OR DI (N = 130). PRIMARY OUTCOMES WERE CHANGE IN PLASMA LEVELS OF ADIPOKINES (LEPTIN, ADIPONECTIN, AND LEPTIN:ADIPONECTIN RATIO), MARKERS OF INFLAMMATION (TUMOR NECROSIS FACTOR [TNF]-ALPHA, INTERLEUKIN [IL]-6), MARKERS OF OXIDATIVE STRESS (THIOBARBITURIC ACID REACTIVE SUBSTANCES [TBARS], 8-HYDROXY-2'-DEOXYGUANOSINE [8-OHDG], AND SUPEROXIDE DISMUTASE [SOD]) MEASURED AT BASELINE, 2 WEEKS, AND 12 WEEKS. YBLI GROUP SHOWED A SIGNIFICANT DECREASE IN LEPTIN, LEPTIN:ADIPONECTIN RATIO, IL-6, 8-OHDG, AND TBARS LEVELS, WHEREAS THERE WAS A SIGNIFICANT INCREASE IN ADIPONECTIN AND SOD LEVELS. NO SIGNIFICANT CHANGES WERE NOTICED IN DI ALONE GROUP. YBLI SHOWED SIGNIFICANTLY GREATER REDUCTION IN TBARS LEVELS THAN IN DI GROUP, SUGGESTIVE OF REDUCED OXIDATIVE STRESS IN ADULTS WITH MET S. A 12 WEEK YBLI HAD A POSITIVE IMPACT ON OXIDATIVE STRESS VERSUS DI ALONE IN ADULTS WITH MET S.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
8  993  24 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
9  985  42 EFFECTS OF HATHA YOGA AND OMKAR MEDITATION ON CARDIORESPIRATORY PERFORMANCE, PSYCHOLOGIC PROFILE, AND MELATONIN SECRETION. OBJECTIVES: TO EVALUATE EFFECTS OF HATHA YOGA AND OMKAR MEDITATION ON CARDIORESPIRATORY PERFORMANCE, PSYCHOLOGIC PROFILE, AND MELATONIN SECRETION. SUBJECTS AND METHODS: THIRTY HEALTHY MEN IN THE AGE GROUP OF 25-35 YEARS VOLUNTEERED FOR THE STUDY. THEY WERE RANDOMLY DIVIDED IN TWO GROUPS OF 15 EACH. GROUP 1 SUBJECTS SERVED AS CONTROLS AND PERFORMED BODY FLEXIBILITY EXERCISES FOR 40 MINUTES AND SLOW RUNNING FOR 20 MINUTES DURING MORNING HOURS AND PLAYED GAMES FOR 60 MINUTES DURING EVENING HOURS DAILY FOR 3 MONTHS. GROUP 2 SUBJECTS PRACTICED SELECTED YOGIC ASANAS (POSTURES) FOR 45 MINUTES AND PRANAYAMA FOR 15 MINUTES DURING THE MORNING, WHEREAS DURING THE EVENING HOURS THESE SUBJECTS PERFORMED PREPARATORY YOGIC POSTURES FOR 15 MINUTES, PRANAYAMA FOR 15 MINUTES, AND MEDITATION FOR 30 MINUTES DAILY, FOR 3 MONTHS. ORTHOSTATIC TOLERANCE, HEART RATE, BLOOD PRESSURE, RESPIRATORY RATE, DYNAMIC LUNG FUNCTION (SUCH AS FORCED VITAL CAPACITY, FORCED EXPIRATORY VOLUME IN 1 SECOND, FORCED EXPIRATORY VOLUME PERCENTAGE, PEAK EXPIRATORY FLOW RATE, AND MAXIMUM VOLUNTARY VENTILATION), AND PSYCHOLOGIC PROFILE WERE MEASURED BEFORE AND AFTER 3 MONTHS OF YOGIC PRACTICES. SERIAL BLOOD SAMPLES WERE DRAWN AT VARIOUS TIME INTERVALS TO STUDY EFFECTS OF THESE YOGIC PRACTICES AND OMKAR MEDITATION ON MELATONIN LEVELS. RESULTS: YOGIC PRACTICES FOR 3 MONTHS RESULTED IN AN IMPROVEMENT IN CARDIORESPIRATORY PERFORMANCE AND PSYCHOLOGIC PROFILE. THE PLASMA MELATONIN ALSO SHOWED AN INCREASE AFTER THREE MONTHS OF YOGIC PRACTICES. THE SYSTOLIC BLOOD PRESSURE, DIASTOLIC BLOOD PRESSURE, MEAN ARTERIAL PRESSURE, AND ORTHOSTATIC TOLERANCE DID NOT SHOW ANY SIGNIFICANT CORRELATION WITH PLASMA MELATONIN. HOWEVER, THE MAXIMUM NIGHT TIME MELATONIN LEVELS IN YOGA GROUP SHOWED A SIGNIFICANT CORRELATION (R = 0.71, P < 0.05) WITH WELL-BEING SCORE. CONCLUSION: THESE OBSERVATIONS SUGGEST THAT YOGIC PRACTICES CAN BE USED AS PSYCHOPHYSIOLOGIC STIMULI TO INCREASE ENDOGENOUS SECRETION OF MELATONIN, WHICH, IN TURN, MIGHT BE RESPONSIBLE FOR IMPROVED SENSE OF WELL-BEING.	2004	
                                                                                                                                                                                                                                                                                                                                                                                                                           
10 1045  44 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	

11 2076  35 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

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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
13 1426  40 IMPROVEMENT OF GLUTATHIONE AND TOTAL ANTIOXIDANT STATUS WITH YOGA. OBJECTIVE: SEVERAL STUDIES SUGGEST THAT YOGA CAN DECREASE OXIDATIVE STRESS. HOWEVER REPORTS ARE SCANTY REGARDING WHETHER YOGA TRAINING CAN IMPROVE THE GLUTATHIONE LEVEL OF INDIVIDUAL. THIS STUDY IS DESIGNED TO APPRAISE THE ROLE OF YOGA IN MAINTAINING GLUTATHIONE (REDUCED AND OXIDIZED) LEVELS AND ANTIOXIDANT STATUS. STUDY DESIGN: THIS STUDY WAS CONDUCTED ON HEALTHY MALE VOLUNTEERS FROM THE INDIAN NAVY, WHO WERE DIVIDED INTO TWO GROUPS--A YOGA (N = 30) GROUP AND A CONTROL (N = 21) GROUP. THE YOGA GROUP WAS TRAINED IN YOGA FOR 6 MONTHS. THE YOGA SCHEDULE CONSISTED OF PRAYERS, ASANA, PRANAYAMA, AND MEDITATION. THE CONTROL GROUP PRACTICED ROUTINE PHYSICAL TRAINING EXERCISE FOR 6 MONTHS. BLOOD SAMPLES WERE COLLECTED WHEN THE VOLUNTEERS WERE IN FASTING CONDITION BEFORE AND AFTER COMPLETION OF 6-MONTH TRAINING PERIOD. REDUCED AND OXIDIZED GLUTATHIONE, GLUTATHIONE REDUCTASE ACTIVITY AND TOTAL ANTIOXIDANT STATUS (TAS) WERE ESTIMATED. RESULTS: REDUCED GLUTATHIONE LEVEL INCREASED SIGNIFICANTLY (P < 0.05) IN THE YOGA GROUP AFTER COMPLETION OF TRAINING. GLUTATHIONE REDUCTASE ACTIVITY INCREASED SIGNIFICANTLY IN THE CONTROL GROUP (P < 0.05). TAS INCREASED SIGNIFICANTLY (P < 0.001) IN THE YOGA GROUP AND DECREASED SIGNIFICANTLY (P < 0.001) IN THE CONTROL GROUP. CONCLUSIONS: REGULAR PRACTICE OF YOGA CAN MAINTAIN OR IMPROVE ANTIOXIDANT LEVEL OF THE BODY. THE CLINICAL RELEVANCE IS THAT YOGA PRACTICE CAN BE USED TO MAINTAIN THE ANTIOXIDANT DEFENSE SYSTEM UNDER STRESSFUL CONDITIONS OF TRAINING AS OBSERVED IN THE CASE OF SOLDIERS AND ATHLETES.	2007	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
14 1102  43 EFFECTS OF YOGA TRAINING ON BODY COMPOSITION AND OXIDANT-ANTIOXIDANT STATUS AMONG HEALTHY MALE. BACKGROUND: THE STRESSFUL CONDITION MAY CAUSE OXIDATIVE STRESS, WHICH IS RESPONSIBLE FOR VARIOUS DISEASES. AIMS: THE PRESENT STUDY WAS DESIGNED TO FIND OUT WHETHER YOGA HAS IMPACT ON THE REDUCTION OF OXIDATIVE STRESS. METHODS: FOR THE PRESENT STUDY, 95 (N = 95) HEALTHY MALE VOLUNTEERS WITHIN THE AGE GROUP OF 18-24 YEARS WERE INCLUDED, 35 (N = 35) VOLUNTEERS WERE EXCLUDED. THE REMAINING 60 (N = 60) VOLUNTEERS WERE RANDOMLY DIVIDED INTO TWO GROUPS: (A) YOGA GROUP (N = 30) AND (B) CONTROL GROUP (N = 30). YOGA TRAINING WAS GIVEN FOR 60 MIN PER DAY, 6 DAYS PER WEEK FOR 12 WEEKS IN THE YOGA GROUP, WITH NO YOGA TRAINING IN CONTROL GROUP. ASSESSMENT OF BODY COMPOSITION AND OXIDANT-ANTIOXIDANT STATUS WERE PERFORMED IN BOTH THE GROUPS AT BASELINE, BEFORE YOGA TRAINING (0 WEEK) AND AFTER (12 WEEKS) OF THE TRAINING. RESULTS: SIGNIFICANT REDUCTION (P < 0.001) IN THE PERCENTAGE OF BODY FAT AND MALONDIALDEHYDE; SIGNIFICANT ELEVATION (P < 0.001) IN SUPEROXIDE DISMUTASE, CATALASE, REDUCED GLUTATHIONE AND ASCORBIC ACID LEVELS WERE NOTED IN THE YOGA GROUP AFTER 12 WEEKS WHEN COMPARED TO BASELINE DATA (0 WEEK). HOWEVER, THERE WAS NO SIGNIFICANT DIFFERENCE IN HEIGHT, WEIGHT, BODY MASS INDEX, BODY SURFACE AREA AND LEAN BODY MASS AMONG THE YOGA GROUP AFTER 12 WEEKS WHEN COMPARED TO BASELINE DATA. THESE CHANGES MIGHT BE DUE TO YOGA TRAINING. CONCLUSIONS: REGULAR YOGA PRACTICE REDUCES BODY FAT AND OXIDATIVE STRESS. YOGA TRAINING MAY BE HELPFUL TO REDUCE THE CHANCE OF OCCURRENCE OF VARIOUS DISEASES AND HELPS TO MAINTAIN NORMAL HEALTHY LIFESTYLE.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
15 2072  44 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  881  36 EFFECT OF YOGA TRAINING ON INFLAMMATORY CYTOKINES AND C-REACTIVE PROTEIN IN EMPLOYEES OF SMALL-SCALE INDUSTRIES. OBJECTIVE: THE PRESENT STUDY INTENDS TO SEE THE EFFECT OF YOGA PRACTICES ON LIPID PROFILE, INTERLEUKIN (IL)-6, TUMOR NECROSIS FACTOR (TNF)-ALPHA, AND HIGH-SENSITIVITY-C-REACTIVE PROTEIN (HS-CRP) AMONG APPARENTLY HEALTHY ADULTS EXPOSED TO OCCUPATIONAL HAZARDS. MATERIALS AND METHODS: IN THE PRESENT STUDY, 48 PARTICIPANTS AGED 30-58 YEARS (41.5 +/- 5.2) WHO WERE EXPOSED TO OCCUPATIONAL HAZARDS WERE RANDOMIZED INTO TWO GROUPS, THAT IS, EXPERIMENTAL AND WAIT-LIST CONTROL. ALL THE PARTICIPANTS WERE ASSESSED FOR LIPID PROFILE, IL-6, TNF-ALPHA, AND HS-CRP AT THE BASELINE AND AFTER COMPLETION OF 3 MONTHS OF YOGA TRAINING INTERVENTION. THE EXPERIMENTAL GROUP UNDERWENT YOGA TRAINING INTERVENTION FOR 1 H FOR 6 DAYS A WEEK FOR 3 MONTHS, WHEREAS CONTROL GROUP CONTINUED WITH THEIR DAILY ACTIVITIES EXCEPT YOGA TRAINING. DATA ANALYSIS WAS DONE USING STATISTICAL SOFTWARE SPSS VERSION 20.0. DATA WERE ANALYZED USING PAIRED T-TESTS AND INDEPENDENT T-TEST. RESULTS: THE RESULTS OF WITHIN GROUP COMPARISON REVEALED HIGHLY SIGNIFICANT CHANGES IN CHOLESTEROL (P < 0.001), HIGH-DENSITY LIPOPROTEIN (P < 0.001), LOW-DENSITY LIPOPROTEIN (LDL)(P < 0.01), HS-CRP (P < 0.01), IL-6 (P < 0.001), AND TNF-ALPHA (P < 0.001) IN EXPERIMENTAL GROUP. COMPARISON BETWEEN EXPERIMENTAL AND CONTROL GROUP REVEALED SIGNIFICANT CHANGES IN CHOLESTEROL (P < 0.01), LDL (P < 0.05), IL-6 (P < 0.01), TNF-ALPHA (P < 0.01), AND HS-CRP (P < 0.01). CONCLUSION: A YOGA-BASED LIFESTYLE INTERVENTION SEEMS TO BE A HIGHLY PROMISING ALTERNATIVE THERAPY WHICH FAVORABLY ALTERS INFLAMMATORY MARKERS AND METABOLIC RISK FACTORS.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
17  350  37 ASSESSMENT OF CARDIAC AUTONOMIC TONE FOLLOWING LONG SUDARSHAN KRIYA YOGA IN ART OF LIVING PRACTITIONERS. OBJECTIVE: THE BREATHING PROCESSES ARE KNOWN TO MODULATE CARDIAC AUTONOMIC TONE AND IMPROVE PSYCHOLOGICAL STATUS. WE INVESTIGATED CARDIAC AUTONOMIC TONE FOLLOWING LONG SUDARSHAN KRIYA YOGA (SKY) USING HEART RATE VARIABILITY (HRV) AND SKIN CONDUCTANCE LEVEL (SCL). METHODS: THIRTY HEALTHY VOLUNTEERS (AGE 28.3 +/- 8.4 YEARS; 23 M: 7 F) PARTICIPATED IN THE STUDY. ELECTROCARDIOGRAM (ECG) AND SCL WERE RECORDED FOR 5 MIN EACH, BEFORE AND AFTER LONG SKY. LONG SKY IS A COMBINATION OF PRANAYAMA AND CYCLIC RHYTHMIC BREATHING AND IS PERFORMED BY FOLLOWING THE GUIDED AUDIO INSTRUCTIONS. HRV ANALYSIS WAS USED FOR THE ASSESSMENT OF CARDIAC AUTONOMIC TONE. TIME AND FREQUENCY DOMAIN PARAMETERS OF HRV WERE CALCULATED BY USING RR INTERVAL OF ECG. SCL WAS ACQUIRED USING GALVANIC SKIN RESPONSE (GSR) AMPLIFIER OF POWERLAB IN MICROSEIMENS (MUS). RESULTS: TIME DOMAIN PARAMETERS OF HRV, INCLUDING MEAN RR INTERVAL (P = 0.000), RESPIRATORY SINUS ARRHYTHMIA (RSA) (P = 0.037), STANDARD DEVIATION OF ALL NN INTERVALS (SDNN) (P = 0.013), NN50 COUNT DIVIDED BY THE TOTAL NUMBER OF ALL NN INTERVALS (PNN50) (P = 0.004), AND SQUARE ROOT OF THE MEAN OF THE SUM OF THE SQUARES OF DIFFERENCES BETWEEN ADJACENT NN INTERVALS (RMSSD) (P = 0.002) INCREASED, AND MEAN HEART RATE DECREASED (P = 0.000) FOLLOWING LONG SKY. IN FREQUENCY DOMAIN ANALYSIS, POWER OF LOW-FREQUENCY (LF) COMPONENT (P = 0.010) AND LF/HF RATIO (P = 0.008) DECREASED SIGNIFICANTLY, WHEREAS POWER OF HIGH FREQUENCY (HF) SIGNIFICANTLY INCREASED (P = 0.010). SCL DECREASED FOLLOWING LONG SKY, ALTHOUGH IT DID NOT ATTAIN STATISTICAL SIGNIFICANCE. CONCLUSIONS: THE RESULTS SUGGEST THAT LONG SKY INDUCES SIGNIFICANT OSCILLATIONS IN CARDIAC AUTONOMIC TONE. PARASYMPATHETIC ACTIVITY INCREASES AND SYMPATHETIC ACTIVITY DECREASES AND SYMPATHOVAGAL BALANCE IMPROVES FOLLOWING LONG SKY. DECREASE IN SYMPATHETIC ACTIVITY IS ALSO DEMONSTRATED BY DECREASE IN CONDUCTANCE ALTHOUGH IT DID NOT REACH STATISTICAL SIGNIFICANCE. FROM THIS STUDY IT CAN BE CONCLUDED THAT LONG SKY HAS A BENEFICIAL EFFECT ON CARDIAC AUTONOMIC TONE, AND PSYCHOPHYSIOLOGICAL RELAXATION. IT MAY SERVE AS A TOOL TO IMPROVE HRV, WHICH IS THE MARKER OF CARDIOVASCULAR HEALTH.	2017	
                                                                                                                                                                                                                                                                                                       
18 1578  40 MEASUREMENT OF THE EFFECT OF ISHA YOGA ON CARDIAC AUTONOMIC NERVOUS SYSTEM USING SHORT-TERM HEART RATE VARIABILITY. BACKGROUND: BENEFICIAL EFFECTS OF YOGA HAVE BEEN POSTULATED TO BE DUE TO MODULATION OF THE AUTONOMIC NERVOUS SYSTEM. OBJECTIVE: TO ASSESS THE EFFECT OF ISHA YOGA PRACTICES ON CARDIOVASCULAR AUTONOMIC NERVOUS SYSTEM THROUGH SHORT-TERM HEART RATE VARIABILITY (HRV). DESIGN OF THE STUDY: SHORT-TERM HRV OF LONG-TERM REGULAR HEALTHY 14 (12 MALES AND 2 FEMALES) ISHA YOGA PRACTITIONERS WAS COMPARED WITH THAT OF AGE- AND GENDER-MATCHED 14 (12 MALES AND 2 FEMALES) NON-YOGA PRACTITIONERS. METHODS AND MATERIALS: ECG LEAD II AND RESPIRATORY MOVEMENTS WERE RECORDED IN BOTH GROUPS USING POLYRITE DURING SUPINE REST FOR 5 MIN AND CONTROLLED DEEP BREATHING FOR 1 MINUTE. FREQUENCY DOMAIN ANALYSIS [RR INTERVAL IS THE MEAN OF DISTANCE BETWEEN SUBSEQUENT R WAVE PEAKS IN ECG], LOW FREQUENCY (LF) POWER, HIGH FREQUENCY (HF) POWER, LF NORMALIZED UNITS (NU), HF NU, LF/HF RATIO] AND TIME DOMAIN ANALYSIS [STANDARD DEVIATION OF NORMAL TO NORMAL INTERVAL (SDNN), SQUARE OF MEAN SQUARED DIFFERENCE OF SUCCESSIVE NORMAL TO NORMAL INTERVALS (RMSSD), NORMAL TO NORMAL INTERVALS WHICH ARE DIFFERING BY 50 MS (NN50), AND PERCENTAGE OF NN50 (PNN50)] OF HRV VARIABLES WERE ANALYZED FOR SUPINE REST. TIME DOMAIN ANALYSIS WAS RECORDED FOR DEEP BREATHING. RESULTS: RESULTS SHOWED STATISTICALLY SIGNIFICANT DIFFERENCES BETWEEN ISHA YOGA PRACTITIONERS AND CONTROLS IN BOTH FREQUENCY AND TIME DOMAIN ANALYSES OF HRV INDICES, WITH NO DIFFERENCE IN RESTING HEART RATE BETWEEN THE GROUPS. CONCLUSIONS: PRACTITIONERS OF ISHA YOGA SHOWED WELL-BALANCED BENEFICIAL ACTIVITY OF VAGAL EFFERENTS, AN OVERALL INCREASED HRV, AND SYMPATHOVAGAL BALANCE, COMPARED TO NON-YOGA PRACTITIONERS DURING SUPINE REST AND DEEP BREATHING.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
19  867  46 EFFECT OF YOGA REGIMEN ON LUNG FUNCTIONS INCLUDING DIFFUSION CAPACITY IN CORONARY ARTERY DISEASE PATIENTS: A RANDOMIZED CONTROLLED STUDY. BACKGROUND: LUNG FUNCTIONS ARE FOUND TO BE IMPAIRED IN CORONARY ARTERY DISEASE (CAD), CONGESTIVE HEART FAILURE, LEFT VENTRICULAR DYSFUNCTION, AND AFTER CARDIAC SURGERY. DIFFUSION CAPACITY PROGRESSIVELY WORSENS AS THE SEVERITY OF CAD INCREASES DUE TO REDUCTION IN LUNG TISSUE PARTICIPATING IN GAS EXCHANGE. AIMS AND OBJECTIVES: PRANAYAMA BREATHING EXERCISES AND YOGIC POSTURES MAY PLAY AN IMPRESSIVE ROLE IN IMPROVING CARDIO-RESPIRATORY EFFICIENCY AND FACILITATING GAS DIFFUSION AT THE ALVEOLO-CAPILLARY MEMBRANE. THIS STUDY WAS DONE TO SEE THE EFFECT OF YOGA REGIMEN ON LUNG FUNCTIONS PARTICULARLY DIFFUSION CAPACITY IN CAD PATIENTS. MATERIALS AND METHODS: A TOTAL OF 80 STABLE CAD PATIENTS BELOW 65 YEARS OF AGE OF BOTH SEXES WERE SELECTED AND RANDOMIZED INTO TWO GROUPS OF 40 EACH. GROUP I CAD PATIENTS WERE GIVEN YOGA REGIMEN FOR 3 MONTHS WHICH CONSISTED OF YOGIC POSTURES, PRANAYAMA BREATHING EXERCISES, DIETARY MODIFICATION, AND HOLISTIC TEACHING ALONG WITH THEIR CONVENTIONAL MEDICINE WHILE GROUP II CAD PATIENTS WERE PUT ONLY ON CONVENTIONAL MEDICINE. LUNG FUNCTIONS INCLUDING DIFFUSION CAPACITY WERE RECORDED THRICE IN BOTH THE GROUPS: 0 DAY AS BASELINE, 22(ND) DAY AND ON 90(TH) DAY BY USING COMPUTERIZED MS MEDISOFT CARDIO-RESPIRATORY INSTRUMENT, HYP'AIR COMPACT MODEL OF CARDIO-RESPIRATORY TESTING MACHINE WAS MANUFACTURED BY P K MORGAN, INDIA. THE RECORDED PARAMETERS WERE STATISTICALLY ANALYZED BY REPEATED MEASURES ANOVA FOLLOWED BY TUKEY'S TEST IN BOTH THE GROUPS. CARDIOVASCULAR PARAMETERS WERE ALSO COMPARED BEFORE AND AFTER INTERVENTION IN BOTH THE GROUPS. RESULTS: STATISTICALLY SIGNIFICANT IMPROVEMENTS WERE SEEN IN SLOW VITAL CAPACITY, FORCED VITAL CAPACITY, PEAK EXPIRATORY FLOW RATE, MAXIMUM VOLUNTARY VENTILATION, AND DIFFUSION FACTOR/ TRANSFER FACTOR OF LUNG FOR CARBON MONOXIDE AFTER 3 MONTHS OF YOGA REGIMEN IN GROUP I. FORCED EXPIRATORY VOLUME IN 1(ST) SEC (FEV1), AND FEV1 % ALSO SHOWED A TREND TOWARD IMPROVEMENT ALTHOUGH NOT STATISTICALLY SIGNIFICANT. HR, SBP AND DBP ALSO SHOWED SIGNIFICANT IMPROVEMENT IN GROUP-I PATIENTS WHO FOLLOWED YOGA REGIMEN. CONCLUSIONS: YOGA REGIMEN WAS FOUND TO IMPROVE LUNG FUNCTIONS AND DIFFUSION CAPACITY IN CAD PATIENTS BESIDES IMPROVING CARDIOVASCULAR FUNCTIONS. THUS, IT CAN BE USED AS A COMPLIMENTARY OR ADJUNCT THERAPY ALONG WITH THE CONVENTIONAL MEDICINE FOR THEIR TREATMENT AND REHABILITATION.	2015	
                                                                          
20 2507  46 YOGA BASED CARDIAC REHABILITATION AFTER CORONARY ARTERY BYPASS SURGERY: ONE-YEAR RESULTS ON LVEF, LIPID PROFILE AND PSYCHOLOGICAL STATES--A RANDOMIZED CONTROLLED STUDY. OBJECTIVE: TO COMPARE THE LONG TERM EFFECTS OF YOGA BASED CARDIAC REHABILITATION PROGRAM WITH ONLY PHYSIOTHERAPY BASED PROGRAM AS AN ADD-ON TO CONVENTIONAL REHABILITATION AFTER CORONARY ARTERY BYPASS GRAFTING (CABG) ON RISK FACTORS. METHODS: IN THIS SINGLE BLIND PROSPECTIVE RANDOMIZED PARALLEL TWO ARMED ACTIVE CONTROL STUDY, 1026 PATIENTS POSTED FOR CABG AT NARAYANA HRUDAYALAYA INSTITUTE OF CARDIAC SCIENCES, BENGALURU (INDIA) WERE SCREENED. OF THESE, 250 MALE PARTICIPANTS (35-65 YEARS) WHO SATISFIED THE SELECTION CRITERIA AND CONSENTED WERE RANDOMIZED INTO TWO GROUPS. WITHIN AND BETWEEN GROUP COMPARISONS WERE DONE AT THREE POINTS OF FOLLOW UP (I.E. 6TH WEEK, 6TH MONTH, AND 12TH MONTH) BY USING WILCOXON'S SIGNED RANKS TEST AND MANN WHITNEY U TEST RESPECTIVELY. RESULTS: YOGA GROUP HAD SIGNIFICANTLY (P = 0.001, MANN WHITNEY) BETTER IMPROVEMENT IN LVEF THAN CONTROL GROUP IN THOSE WITH ABNORMAL BASELINE EF (<53%) AFTER 1 YEAR. THERE WAS A BETTER REDUCTION IN BMI IN THE YOGA GROUP (P = 0.038, BETWEEN GROUPS) IN THOSE WITH HIGH BASELINE BMI (>/=23) AFTER 12 MONTHS. YOGA GROUP SHOWED SIGNIFICANT (P = 0.008, WILCOXON'S) REDUCTION IN BLOOD GLUCOSE AT ONE YEAR IN THOSE WITH HIGH BASELINE FBS >/=110 MG/DL. THERE WAS SIGNIFICANTLY BETTER IMPROVEMENT IN YOGA THAN THE CONTROL GROUP IN HDL (P = 0.003), LDL (P = 0.01) AND VLDL (P = 0.03) IN THOSE WITH ABNORMAL BASELINE VALUES. THERE WAS SIGNIFICANTLY BETTER IMPROVEMENT (P = 0.02, BETWEEN GROUPS) IN POSITIVE AFFECT IN YOGA GROUP. WITHIN YOGA GROUP, THERE WAS SIGNIFICANT DECREASE IN PERCEIVED STRESS (P = 0.001), ANXIETY (P = 0.001), DEPRESSION (P = 0.001), AND NEGATIVE AFFECT (P = 0.03) WHILE IN THE CONTROL GROUP THERE WAS REDUCTION (P = 0.003) ONLY IN SCORES ON ANXIETY. CONCLUSION: ADDITION OF YOGA BASED RELAXATION TO CONVENTIONAL POST-CABG CARDIAC REHABILITATION HELPS IN BETTER MANAGEMENT OF RISK FACTORS IN THOSE WITH ABNORMAL BASELINE VALUES AND MAY HELP IN PREVENTING RECURRENCE.	2014
