1  650 150 DYNAMICS OF HEART RATE VARIABILITY UNDER THE INFLUENCE OF COURSE YOGA BREATHING EXERCISES ON HEALTHY YOUNG PEOPLE. OBJECTIVE: INTRODUCTION: HEART RATE VARIABILITY IS A HIGHLY INFORMATIVE NON-INVASIVE METHOD OF RESEARCH NOT ONLY FOR THE FUNCTIONAL STATE OF THE CARDIOVASCULAR SYSTEM AND ALSO FOR THE INTEGRATIVE REGULATORY ACTIVITY OF THE AUTONOMIC NERVOUS SYSTEM. THE POSITIVE EFFECT OF DIAPHRAGMATIC BREATHING IS POSITIVE IN THE MODE OF BIOLOGICAL FEEDBACK USING PORTABLE DEVICES, BUT THERE IS LITTLE EVIDENCE OF THE USE OF YOGA BREATHING GYMNASTICS IN ORDER TO INFLUENCE THE HEART RATE VARIABILITY. THE AIM: TO COMPARE THE POSSIBILITIES OF USING COURSES OF BREATHING GYMNASTICS OF YOGIS AND DIAPHRAGMATIC BREATHING SESSIONS IN THE MODE OF BIOLOGICAL FEEDBACK USING A PORTABLE DEVICE. PATIENTS AND METHODS: MATERIALS AND METHODS: THE STUDY INVOLVED 70 PRACTICALLY HEALTHY FOREIGNERS, WHO WERE DIVIDED INTO 2 GROUPS OF 35 PEOPLE. PARTICIPANTS OF THE 1ST GROUP DAILY ENGAGE IN RESPIRATORY EXERCISES PRANAYAMA FOR 15 MINUTES IN 1 MONTH. PARTICIPANTS IN THE 2ND GROUP USED THE MYCALMBEAT PORTABLE DEVICE. HEART RATE VARIABILITY WAS REGISTERED BY USING THE COMPUTER DIAGNOSTIC COMPLEX "CARDIOLAB" ("KHAI-MEDIKA", UKRAINE). RESULTS: RESULTS: IN BOTH GROUPS THERE WAS SIMILAR DYNAMICS OF HEART RATE VARIABILITY INDICES, BUT ITS SEVERITY WAS DIFFERENT. THE COMMON INTEGRAL EFFECT WAS A SIGNIFICANT GROWTH OF HEART RATE VARIABILITY BOTH ACCORDING TO STATISTICAL AND SPECTRAL INDICATORS - TOTAL POWER INCREASED, AS WELL AS HIGH-FREQUENCY COMPONENT. THE POWER OF THE VERY-LOW FREQUENCY WAVES HAS PROBABLY DECREASED ONLY IN THE GROUP WITH THE DEVICE. IN THE PERCENTAGE STRUCTURE OF THE CARDIAC RHYTHM SPECTRUM, THE SPECIFIC WEIGHT OF VERY-LOW FREQUENCY COMPONENT AND THE PERCENTAGE OF HIGH-FREQUENCY COMPONENT INCREASED. CONCLUSION: CONCLUSIONS: RESPIRATORY GYMNASTICS YOGA FOR 15 MINUTES DAILY CONTRIBUTES TO THE GROWTH OF HEART RATE VARIABILITY THROUGH THE SUPPRESSION OF THE CENTRAL LINK (VERY-LOW FREQUENCY COMPONENT) OF REGULATION OF CARDIAC RHYTHM AND INCREASED ACTIVITY OF PARASYMPATHETIC INFLUENCES (HIGH-FREQUENCY COMPONENT), AS WELL AS THE REDISTRIBUTION OF REGULATORY ACTIVITY OF THE CENTRAL NERVOUS SYSTEM BETWEEN THE CENTRAL AND PERIPHERAL LINKS OF REGULATION OF THE CARDIAC RHYTHM IN FAVOR OF THE LATTER.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
2  297  41 ALTERNATE NOSTRIL BREATHING AT DIFFERENT RATES AND ITS INFLUENCE ON HEART RATE VARIABILITY IN NON PRACTITIONERS OF YOGA. INTRODUCTION: HEART RATE VARIABILITY IS A MEASURE OF MODULATION IN AUTONOMIC INPUT TO THE HEART AND IS ONE OF THE MARKERS OF AUTONOMIC FUNCTIONS. THOUGH THERE ARE MANY STUDIES ON THE LONG TERM INFLUENCE OF BREATHING ON HRV (HEART RATE VARIABILITY) THERE ARE ONLY A FEW STUDIES ON THE IMMEDIATE EFFECT OF BREATHING ESPECIALLY ALTERNATE NOSTRIL BREATHING ON HRV. THIS STUDY FOCUSES ON THE IMMEDIATE EFFECTS OF ALTERNATE NOSTRIL BREATHING AND THE INFLUENCE OF DIFFERENT BREATHING RATES ON HRV. MATERIALS AND METHODS: THE STUDY WAS DONE ON 25 SUBJECTS IN THE AGE GROUP OF 17-35 YEARS. ECG AND RESPIRATION WERE RECORDED BEFORE INTERVENTION AND IMMEDIATELY AFTER THE SUBJECTS WERE ASKED TO PERFORM ALTERNATE NOSTRIL BREATHING FOR FIVE MINUTES. RESULTS: LOW FREQUENCY (LF) WHICH IS A MARKER OF SYMPATHETIC ACTIVITY INCREASED, HIGH FREQUENCY (HF) WHICH IS A MARKER OF PARASYMPATHETIC ACTIVITY DECREASED AND THEIR RATIO LF/HF WHICH IS A MARKER OF SYMPATHO/VAGAL BALANCE INCREASED IMMEDIATELY AFTER 6 AND 12 MINUTES IN COMPARISON TO BASELINE VALUES WHEREAS THERE WAS NO SIGNIFICANT DIFFERENCE IN THE MEANS OF THESE COMPONENTS WHEN BOTH 6 AND 12 MINUTES WERE COMPARED. CONCLUSION: IMMEDIATE EFFECTS OF ALTERNATE NOSTRIL BREATHING ON HRV IN NON PRACTITIONERS OF YOGIC BREATHING ARE VERY DIFFERENT FROM THE LONG TERM INFLUENCE OF YOGIC BREATHING ON HRV WHICH SHOW A PREDOMINANT PARASYMPATHETIC INFLUENCE ON THE HEART.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
3  427  41 CAN YOGA BOOST ACCESS TO THE BODILY AND EMOTIONAL SELF? CHANGES IN HEART RATE VARIABILITY AND IN AFFECTIVE EVALUATION BEFORE, DURING AND AFTER A SINGLE SESSION OF YOGA EXERCISE WITH AND WITHOUT INSTRUCTIONS OF CONTROLLED BREATHING AND MINDFUL BODY AWARENESS IN YOUNG HEALTHY WOMEN. EXERCISE IS INDISPENSABLE FOR A HEALTHY LIFESTYLE. YOGA EXERCISE CAN HAVE POSITIVE EFFECTS ON WELL-BEING AND ON CARDIAC AUTONOMIC ACTIVITY MAKING IT AN IDEAL INTERVENTION FOR IMPROVING MIND-BODY INTERACTIONS AND RESILIENCE TO PHYSICAL AND MENTAL STRESSORS. EMOTIONS TRIGGER ESPECIALLY STRONG BODILY AND AFFECTIVE-COGNITIVE RESPONSES BECAUSE OF THEIR SOCIAL RELEVANCE FOR THE SELF AND THEIR BIOLOGICAL RELEVANCE OF MOBILIZING THE ORGANISM FOR ACTION. THIS STUDY INVESTIGATES WHETHER CHANGES IN EMOTION PROCESSING RELATED TO SELF-OTHER REFERENTIAL PROCESSING AND CHANGES IN CARDIAC AUTONOMIC ACTIVITY, REFLECTED BY HEART RATE VARIABILITY (HRV), OCCUR IMMEDIATELY AFTER ALREADY A SINGLE SESSION OF YOGA EXERCISE WHEN YOGA POSTURES ARE PRACTICED WITH OR WITHOUT BREATHING- AND MINDFUL BODY AWARENESS INSTRUCTIONS. WOMEN, ALL UNIVERSITY STUDENTS (N = 34, FINAL SAMPLE: N = 30, N = 25 NAIVE TO YOGA PRACTICE) WERE RANDOMLY ASSIGNED TO TWO EXPERIMENTAL GROUPS WHO PERFORMED THE SAME YOGA EXERCISES WITH OR WITHOUT CONTROLLED BREATHING AND MINDFULNESS INSTRUCTIONS. EMOTIONAL, SELF-OTHER REFERENTIAL PROCESSING, AWARENESS OF BODILY SIGNALS AND HRV INDICATORS WERE INVESTIGATED BEFORE AND AFTER THE EXERCISE USING STANDARDIZED EXPERIMENTAL TASKS, STANDARDIZED QUESTIONNAIRES, AND MOBILE RECORDING DEVICES. EXERCISING FOR 30 MINUTES CHANGED CARDIAC ACTIVITY SIGNIFICANTLY. HRV MEASURES SHOWED ADAPTABILITY OF CARDIAC ACTIVITY DURING THE EXERCISE AS WELL AS DURING THE AFFECTIVE TASK POST- TO PRE-EXERCISE. EXERCISING WITH BREATHING INSTRUCTIONS AND MINDFUL BODY AWARENESS HAD NO SUPERIOR EFFECTS ON CARDIAC, PARTICULARLY PARASYMPATHETIC ACTIVITY, COMPARED TO PRACTICING THE SAME MOVEMENTS WITHOUT SUCH EXPLICIT INSTRUCTIONS. SELF-REFERENTIAL PROCESSING DID NOT CHANGE; HOWEVER, PARTICIPANTS WERE FASTER AND MORE ACCURATE IN THEIR AFFECTIVE JUDGMENTS OF EMOTIONAL STIMULI [REGARDLESS OF THEIR REFERENCE (SELF/OTHER)], AND SHOWED BETTER AWARENESS OF BODILY SIGNALS AFTER COMPARED TO BEFORE THE EXERCISE SESSION. THE RESULTS SUPPORT IMMEDIATE, ADAPTIVE EFFECTS OF YOGA EXERCISE ON CARDIAC AND AFFECTIVE-COGNITIVE PROCESSING IN AN ALL-FEMALE HEALTHY SAMPLE. THEREFORE, YOGA EXERCISE COULD BE RECOMMENDED AS A PHYSICAL ACTIVITY FOR BOOSTING CARDIAC AND EMOTIONAL RESILIENCE IN THIS TARGET GROUP.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
4  452  40 CHANGES IN HEART RATE VARIABILITY AFTER YOGA ARE DEPENDENT ON HEART RATE VARIABILITY AT BASELINE AND DURING YOGA: A STUDY SHOWING AUTONOMIC NORMALIZATION EFFECT IN YOGA-NAIVE AND EXPERIENCED SUBJECTS. BACKGROUND: YOGA THERAPY IS WIDELY APPLIED TO THE MAINTENANCE OF HEALTH AND TO TREATMENT OF VARIOUS ILLNESSES. PREVIOUS RESEARCHES INDICATE THE INVOLVEMENT OF AUTONOMIC CONTROL IN ITS EFFECTS, ALTHOUGH THE GENERAL AGREEMENT HAS NOT BEEN REACHED REGARDING THE ACUTE MODULATION OF AUTONOMIC FUNCTION. AIM: THE PRESENT STUDY AIMED AT REVEALING THE ACUTE EFFECT OF YOGA ON THE AUTONOMIC ACTIVITY USING HEART RATE VARIABILITY (HRV) MEASUREMENT. METHODS: TWENTY-SEVEN HEALTHY CONTROLS PARTICIPATED IN THE PRESENT STUDY. FIFTEEN OF THEM (39.5 +/- 8.5 YEARS OLD) WERE NAIVE AND 12 (45.1 +/- 7.0 YEARS OLD) WERE EXPERIENCED IN YOGA. YOGA SKILLS INCLUDED BREATH AWARENESS, TWO TYPES OF ASANA, AND TWO TYPES OF PRANAYAMA. HRV WAS MEASURED AT THE BASELINE, DURING YOGA, AND AT THE RESTING STATE AFTER YOGA. RESULTS: IN BOTH YOGA-NAIVE AND EXPERIENCED PARTICIPANTS, THE CHANGES IN LOW-FREQUENCY (LF) COMPONENT OF HRV AND ITS RATIO TO HIGH-FREQUENCY (HF) COMPONENT (LF/HF) AFTER YOGA WERE FOUND TO BE CORRELATED NEGATIVELY WITH THE BASELINE DATA. THE CHANGES IN LF AFTER YOGA WERE ALSO CORRELATED WITH LF DURING YOGA. THE CHANGES IN HF AS WELL AS THE RAW HRV DATA AFTER YOGA WERE NOT RELATED TO THE BASELINE HRV OR THE HRV DURING YOGA. CONCLUSION: THE RESULTS INDICATE THAT YOGA LEADS TO AN INCREASE IN LF WHEN LF IS LOW AND LEADS TO A DECREASE IN LF WHEN IT IS HIGH AT THE BASELINE. THIS NORMALIZATION OF LF IS DEPENDENT ON THE AUTONOMIC MODULATION DURING YOGA AND MAY UNDERLIE THE CLINICAL EFFECTIVENESS OF YOGA THERAPY BOTH IN YOGA-NAIVE AND EXPERIENCED SUBJECTS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
5 2409  40 YOGA AND HEART RATE VARIABILITY: A COMPREHENSIVE REVIEW OF THE LITERATURE. HEART RATE VARIABILITY (HRV) HAS BEEN USED AS A PROXY FOR HEALTH AND FITNESS AND INDICATOR OF AUTONOMIC REGULATION AND THEREFORE, APPEARS WELL PLACED TO ASSESS THE CHANGES OCCURRING WITH MIND.-BODY PRACTICES THAT FACILITATE AUTONOMIC BALANCE. WHILE MANY STUDIES SUGGEST THAT YOGA INFLUENCES HRV, SUCH STUDIES HAVE NOT BEEN SYSTEMATICALLY REVIEWED. WE AIMED TO SYSTEMATICALLY REVIEW ALL PUBLISHED PAPERS THAT REPORT ON YOGA PRACTICES AND HRV. A COMPREHENSIVE SEARCH OF MULTIPLE DATABASES WAS CONDUCTED AND ALL STUDIES THAT REPORTED A MEASURE OF HRV ASSOCIATED WITH ANY YOGA PRACTICE WERE INCLUDED. STUDIES WERE CATEGORIZED BY THE STUDY DESIGN AND TYPE OF YOGA PRACTICE. A TOTAL OF 59 STUDIES WERE REVIEWED INVOLVING A TOTAL OF 2358 PARTICIPANTS. MOST STUDIES WERE PERFORMED IN INDIA ON RELATIVELY SMALL NUMBERS OF HEALTHY MALE YOGA PRACTITIONERS DURING A SINGLE LABORATORY SESSION. OF THE REVIEWED STUDIES, 15 WERE RANDOMIZED CONTROLLED TRIALS WITH 6 HAVING A JADAD SCORE OF 3. THE REVIEWED STUDIES SUGGEST THAT YOGA CAN AFFECT CARDIAC AUTONOMIC REGULATION WITH INCREASED HRV AND VAGAL DOMINANCE DURING YOGA PRACTICES. REGULAR YOGA PRACTITIONERS WERE ALSO FOUND TO HAVE INCREASED VAGAL TONE AT REST COMPARED TO NON-YOGA PRACTITIONERS. IT IS PREMATURE TO DRAW ANY FIRM CONCLUSIONS ABOUT YOGA AND HRV AS MOST STUDIES WERE OF POOR QUALITY, WITH SMALL SAMPLE SIZES AND INSUFFICIENT REPORTING OF STUDY DESIGN AND STATISTICAL METHODS. RIGOROUS STUDIES WITH DETAILED REPORTING OF YOGA PRACTICES AND ANY CORRESPONDING CHANGES IN RESPIRATION ARE REQUIRED TO DETERMINE THE EFFECT OF YOGA ON HRV.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
6  341  43 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	

7 2736  31 YOGA POSES INCREASE SUBJECTIVE ENERGY AND STATE SELF-ESTEEM IN COMPARISON TO 'POWER POSES'. RESEARCH ON BENEFICIAL CONSEQUENCES OF YOGA FOCUSES ON THE EFFECTS OF YOGIC BREATHING AND MEDITATION. LESS IS KNOWN ABOUT THE PSYCHOLOGICAL EFFECTS OF PERFORMING YOGA POSTURES. THE PRESENT STUDY INVESTIGATED THE EFFECTS OF YOGA POSES ON SUBJECTIVE SENSE OF ENERGY AND SELF-ESTEEM. THE EFFECTS OF YOGA POSTURES WERE COMPARED TO THE EFFECTS OF 'POWER POSES,' WHICH ARGUABLY INCREASE THE SENSE OF POWER AND SELF-CONFIDENCE DUE TO THEIR ASSOCIATION WITH INTERPERSONAL DOMINANCE (CARNEY ET AL., 2010). THE STUDY TESTED THE NOVEL PREDICTION THAT YOGA POSES, WHICH ARE NOT ASSOCIATED WITH INTERPERSONAL DOMINANCE BUT INCREASE BODILY ENERGY, WOULD INCREASE THE SUBJECTIVE FEELING OF ENERGY AND THEREFORE INCREASE SELF-ESTEEM COMPARED TO 'HIGH POWER' AND 'LOW POWER' POSES. A TWO FACTORIAL, BETWEEN PARTICIPANTS DESIGN WAS EMPLOYED. PARTICIPANTS PERFORMED EITHER TWO STANDING YOGA POSES WITH OPEN FRONT OF THE BODY (N = 19), TWO STANDING YOGA POSES WITH COVERED FRONT OF THE BODY (N = 22), TWO EXPANSIVE, HIGH POWER POSES (N = 21), OR TWO CONSTRICTIVE, LOW POWER POSES (N = 20) FOR 1-MIN EACH. THE RESULTS SHOWED THAT YOGA POSES IN COMPARISON TO 'POWER POSES' INCREASED SELF-ESTEEM. THIS EFFECT WAS MEDIATED BY AN INCREASED SUBJECTIVE SENSE OF ENERGY AND WAS OBSERVED WHEN BASELINE TRAIT SELF-ESTEEM WAS CONTROLLED FOR. THESE RESULTS SUGGEST THAT THE EFFECTS OF PERFORMING OPEN, EXPANSIVE BODY POSTURES MAY BE DRIVEN BY PROCESSES OTHER THAN THE POSES' ASSOCIATION WITH INTERPERSONAL POWER AND DOMINANCE. THIS STUDY DEMONSTRATES THAT POSITIVE EFFECTS OF YOGA PRACTICE CAN OCCUR AFTER PERFORMING YOGA POSES FOR ONLY 2 MIN.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
8 1027  38 EFFECTS OF YOGA BREATHING PRACTICE ON HEART RATE VARIABILITY IN HEALTHY ADOLESCENTS: A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: THIS STUDY WAS CONDUCTED AMONG HEALTHY ADOLESCENTS TO ASSESS THE EFFECTS OF A YOGA BREATHING PRACTICE (BHRAMARI PRANAYAMA, BHR.P) TOWARDS CARDIAC AUTONOMIC FUNCTION USING HEART RATE VARIABILITY (HRV) PARAMETERS. METHODS: OF THE 730 ELIGIBLE SUBJECTS SCREENED, 520 HEALTHY ADOLESCENTS WHO MET THE INCLUSION AND EXCLUSION CRITERIA WERE RANDOMLY ASSIGNED TO EITHER YOGA BREATHING GROUP (N=260) OR CONTROL GROUP (N=260). THE YOGA BREATHING GROUP PRACTICED BHR.P. FIVE DAYS A WEEK FOR A DURATION OF SIX MONTHS WHILE THE CONTROL GROUP CONTINUED WITH THEIR DAILY ROUTINE WITHOUT ANY INTERVENTION. OUTCOME MEASURES WERE TIME AND FREQUENCY DOMAIN OF HRV IN BOTH GROUPS WHICH WERE ASSESSED BEFORE AND AFTER THE INTERVENTION USING LEAD II ECG. LINEAR MODELS WERE USED IN THE ANALYSIS OF SHORT TERM HRV. RESULTS: AFTER 6 MONTHS OF YOGA BREATHING, THE TIME DOMAIN PARAMETERS OF SHORT TERM HRV SHOWED SIGNIFICANT (P<0.05) IMPROVEMENT TOWARDS THE PARASYMPATHETIC DOMAIN. FREQUENCY DOMAIN PARAMETERS ALSO SHOWED THE SAME DIRECTION OF CHANGES. IN CONTRAST, CONTROL GROUP SUBJECTS SHOWED A TREND TOWARDS A SYMPATHETIC DOMAIN. CONCLUSION: THE PRESENT STUDY SHOWED A POSITIVE SHIFT IN CARDIAC AUTONOMIC MODULATION TOWARDS PARASYMPATHETIC PREDOMINANCE AFTER 6 MONTHS OF YOGA BREATHING PRACTICE AMONG APPARENTLY HEALTHY ADOLESCENTS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
9 1530  34 IYENGAR YOGA INCREASES CARDIAC PARASYMPATHETIC NERVOUS MODULATION AMONG HEALTHY YOGA PRACTITIONERS. RELAXATION TECHNIQUES ARE ESTABLISHED IN MANAGING OF CARDIAC PATIENTS DURING REHABILITATION AIMING TO REDUCE FUTURE ADVERSE CARDIAC EVENTS. IT HAS BEEN HYPOTHESIZED THAT RELAXATION-TRAINING PROGRAMS MAY SIGNIFICANTLY IMPROVE CARDIAC AUTONOMIC NERVOUS TONE. HOWEVER, THIS HAS NOT BEEN PROVEN FOR ALL AVAILABLE RELAXATION TECHNIQUES. WE TESTED THIS ASSUMPTION BY INVESTIGATING CARDIAC VAGAL MODULATION DURING YOGA.WE EXAMINED 11 HEALTHY YOGA PRACTITIONERS (7 WOMEN AND 4 MEN, MEAN AGE: 43 +/- 11; RANGE: 26-58 YEARS). EACH INDIVIDUAL WAS SUBJECTED TO TRAINING UNITS OF 90 MIN ONCE A WEEK OVER FIVE SUCCESSIVE WEEKS. DURING TWO SESSIONS, THEY PRACTICED A YOGA PROGRAM DEVELOPED FOR CARDIAC PATIENTS BY B.K.S. IYENGAR. ON THREE SESSIONS, THEY PRACTICED A PLACEBO PROGRAM OF RELAXATION. ON EACH TRAINING DAY THEY UNDERWENT AMBULATORY 24 H HOLTER MONITORING. THE GROUP OF YOGA PRACTITIONERS WAS COMPARED TO A MATCHED GROUP OF HEALTHY INDIVIDUALS NOT PRACTICING ANY RELAXATION TECHNIQUES. PARAMETERS OF HEART RATE VARIABILITY (HRV) WERE DETERMINED HOURLY BY A BLINDED OBSERVER. MEAN RR INTERVAL (INTERVAL BETWEEN TWO R-WAVES OF THE ECG) WAS SIGNIFICANTLY HIGHER DURING THE TIME OF YOGA INTERVENTION COMPARED TO PLACEBO AND TO CONTROL (P < 0.001 FOR BOTH). THE INCREASE IN HRV PARAMETERS WAS SIGNIFICANTLY HIGHER DURING YOGA EXERCISE THAN DURING PLACEBO AND CONTROL ESPECIALLY FOR THE PARAMETERS ASSOCIATED WITH VAGAL TONE, I.E. MEAN STANDARD DEVIATION OF NN (NORMAL BEAT TO NORMAL BEAT OF THE ECG) INTERVALS FOR ALL 5-MIN INTERVALS (SDNNI, P < 0.001 FOR BOTH) AND ROOT MEAN SQUARE SUCCESSIVE DIFFERENCE (RMSSD, P < 0.01 FOR BOTH). IN CONCLUSION, RELAXATION BY YOGA TRAINING IS ASSOCIATED WITH A SIGNIFICANT INCREASE OF CARDIAC VAGAL MODULATION. SINCE THIS METHOD IS EASY TO APPLY WITH NO SIDE EFFECTS, IT COULD BE A SUITABLE INTERVENTION IN CARDIAC REHABILITATION PROGRAMS.	2007	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
10 2863  31 YOGA-BASED GUIDED RELAXATION REDUCES SYMPATHETIC ACTIVITY JUDGED FROM BASELINE LEVELS. 35 MALE VOLUNTEERS WHOSE AGES RANGED FROM 20 TO 46 YEARS WERE STUDIED IN TWO SESSIONS OF YOGA-BASED GUIDED RELAXATION AND SUPINE REST. ASSESSMENTS OF AUTONOMIC VARIABLES WERE MADE FOR 15 SUBJECTS, BEFORE, DURING, AND AFTER THE PRACTICES, WHEREAS OXYGEN CONSUMPTION AND BREATH VOLUME WERE RECORDED FOR 25 SUBJECTS BEFORE AND AFTER BOTH TYPES OF RELAXATION. A SIGNIFICANT DECREASE IN OXYGEN CONSUMPTION AND INCREASE IN BREATH VOLUME WERE RECORDED AFTER GUIDED RELAXATION (PAIRED T TEST). THERE WERE COMPARABLE REDUCTIONS IN HEART RATE AND SKIN CONDUCTANCE DURING BOTH TYPES OF RELAXATION. DURING GUIDED RELAXATION THE POWER OF THE LOW FREQUENCY COMPONENT OF THE HEART-RATE VARIABILITY SPECTRUM REDUCED, WHEREAS THE POWER OF THE HIGH FREQUENCY COMPONENT INCREASED, SUGGESTING REDUCED SYMPATHETIC ACTIVITY. ALSO, SUBJECTS WITH A BASELINE RATIO OF LF/HF > 0.5 SHOWED A SIGNIFICANT DECREASE IN THE RATIO AFTER GUIDED RELAXATION, WHILE SUBJECTS WITH A RATIO < OR = 0.5 AT BASELINE SHOWED NO SUCH CHANGE. THE RESULTS SUGGEST THAT SYMPATHETIC ACTIVITY DECREASED AFTER GUIDED RELAXATION BASED ON YOGA, DEPENDING ON THE BASELINE LEVELS.	2002	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
11 1424  20 IMPROVEMENT IN PHYSIOLOGICAL AND PSYCHOLOGICAL PARAMETERS AFTER 6 MONTHS OF YOGA PRACTICE. YOGA IS BELIEVED TO HAVE BENEFICIAL EFFECTS ON COGNITION, ATTENUATION OF EMOTIONAL INTENSITY AND STRESS REDUCTION. PREVIOUS STUDIES WERE MAINLY PERFORMED ON EASTERN EXPERIENCED PRACTITIONERS OR UNHEALTHY SUBJECTS UNDERGOING CONCOMITANT CONVENTIONAL THERAPIES. FURTHER INVESTIGATION IS NEEDED ON THE EFFECTS OF YOGA PER SE, AS WELL AS ITS POSSIBLE PREVENTIVE BENEFITS ON HEALTHY SUBJECTS. WE INVESTIGATED THE EFFECTS OF YOGA ON MEMORY AND PSYCHOPHYSIOLOGICAL PARAMETERS RELATED TO STRESS, COMPARING YOGA PRACTICE AND CONVENTIONAL PHYSICAL EXERCISES IN HEALTHY MEN (PREVIOUSLY YOGA-NAIVE). MEMORY TESTS, SALIVARY CORTISOL LEVELS AND STRESS, ANXIETY, AND DEPRESSION INVENTORIES WERE ASSESSED BEFORE AND AFTER 6 MONTHS OF PRACTICE. YOGA PRACTITIONERS SHOWED IMPROVEMENT OF THE MEMORY PERFORMANCE, AS WELL AS IMPROVEMENTS IN PSYCHOPHYSIOLOGICAL PARAMETERS. THE PRESENT RESULTS SUGGEST THAT REGULAR YOGA PRACTICE CAN IMPROVE ASPECTS OF COGNITION AND QUALITY OF LIFE FOR HEALTHY INDIVIDUALS. AN INDIRECT INFLUENCE OF EMOTIONAL STATE ON COGNITIVE IMPROVEMENT PROMOTED BY YOGA PRACTICE CAN BE PROPOSED.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
12  716  40 EFFECT OF INTEGRATED YOGA PRACTICES ON IMMUNE RESPONSES IN EXAMINATION STRESS - A PRELIMINARY STUDY. BACKGROUND: STRESS IS OFTEN ASSOCIATED WITH AN INCREASED OCCURRENCE OF AUTONOMIC, CARDIOVASCULAR, AND IMMUNE SYSTEM PATHOLOGY. THIS STUDY WAS DONE TO EVALUATE THE IMPACT OF STRESS ON PSYCHOLOGICAL, PHYSIOLOGICAL PARAMETERS, AND IMMUNE SYSTEM DURING MEDICAL TERM -ACADEMIC EXAMINATION AND THE EFFECT OF YOGA PRACTICES ON THE SAME. MATERIALS AND METHODS: THE STUDY WAS CARRIED OUT ON SIXTY FIRST-YEAR MBBS STUDENTS RANDOMLY ASSIGNED TO YOGA GROUP AND CONTROL GROUP (30 EACH). THE YOGA GROUP UNDERWENT INTEGRATED YOGA PRACTICES FOR 35 MINUTES DAILY IN THE PRESENCE OF TRAINED YOGA TEACHER FOR 12 WEEKS. CONTROL GROUP DID NOT UNDERGO ANY KIND OF YOGA PRACTICE OR STRESS MANAGEMENT. PHYSIOLOGICAL PARAMETERS LIKE HEART RATE, RESPIRATORY RATE, AND BLOOD PRESSURE WERE MEASURED. GLOBAL ASSESSMENT OF RECENT STRESS SCALE AND SPIELBERGERS STATE ANXIETY SCORE WERE ASSESSED AT BASELINE AND DURING THE EXAMINATION. SERUM CORTISOL LEVELS, IL-4, AND IFN-GAMMA LEVELS WERE DETERMINED BY ENZYME-LINKED IMMUNOSORBENT ASSAY TECHNIQUE. RESULT: IN THE YOGA GROUP, NO SIGNIFICANT DIFFERENCE WAS OBSERVED IN PHYSIOLOGICAL PARAMETERS DURING THE EXAMINATION STRESS, WHEREAS IN THE CONTROL GROUP, A SIGNIFICANT INCREASE WAS OBSERVED. LIKEWISE, THE INDICATORS OF PSYCHOLOGICAL STRESS SHOWED HIGHLY SIGNIFICANT DIFFERENCE IN CONTROL GROUP COMPARED WITH SIGNIFICANT DIFFERENCE IN YOGA GROUP. DURING THE EXAMINATION, THE INCREASE IN SERUM CORTICAL AND DECREASE IN SERUM IFN-GAMMA IN YOGA GROUP WAS LESS SIGNIFICANT (P<0.01) THAN IN THE CONTROL GROUP (P<0.001). BOTH THE GROUPS DEMONSTRATED AN INCREASE IN SERUM IL-4 LEVELS, THE CHANGES BEING INSIGNIFICANT FOR THE DURATION OF THE STUDY. CONCLUSION: YOGA RESISTS THE AUTONOMIC CHANGES AND IMPAIRMENT OF CELLULAR IMMUNITY SEEN IN EXAMINATION STRESS.	2011

OBJECTIVES: CHANGE IN THE PAST FEW DECADES IN HUMAN LIFE STYLE, NOWADAYS INTERNATIONAL HEALTH ORGANIZATIONS, I.E., WORLD HEALTH ORGANIZATION ARE ALSO FOCUSING ON PREVENTION ALONG WITH TREATMENT ASPECT OF CHRONIC ILLNESS. RESEARCHES FOCUS THAT WOMEN OF AGE GROUP 30-45 YEARS ARE AT INCREASED RISK FOR HYPERTENSION AND HEART DISEASE DUE TO INCREASED WEIGHT. YOGA IS AN EFFECTIVE METHOD TO CONTROL OUR PHYSIOLOGICAL VARIABLES LIKE BLOOD PRESSURE (BP), PULSE, ETC. THE MAIN AIM OF THIS STUDY WAS TO IDENTIFY THE EFFECTS OF YOGA ON PHYSIOLOGICAL VARIABLES. METHODS: THE STUDY WAS AN EXPERIMENTAL STUDY WITH TWO GROUP, PRETEST AND POSTTEST CONTROL GROUP, DESIGN, WHICH WAS CONDUCTED ON 40 FEMALE PARTICIPANTS. PRANAYAMA AND MEDITATION FOR A PERIOD OF 6 WEEKS WAS DONE BY THESE WOMEN. RESULTS: YOGA THERAPY SIGNIFICANTLY REDUCED THE BP (0.000*) AND PULSE RATE (0.000*) OF WOMEN, WHICH WAS ALSO STATISTICALLY PROVED. CONCLUSIONS: YOGA THERAPY CAN BE AN EFFECTIVE METHOD TO CONTROL BP AND PULSE RATE OF PATIENTS WITH CHRONIC DISEASES.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
14 1744  32 PHYSIOLOGICAL AND PSYCHOLOGICAL EFFECTS OF HATHA-YOGA EXERCISE IN HEALTHY WOMEN. HATHA-YOGA HAS BECOME INCREASINGLY POPULAR IN WESTERN COUNTRIES AS A METHOD FOR COPING WITH STRESS. HOWEVER, LITTLE IS KNOWN ABOUT THE PHYSIOLOGICAL AND PSYCHOLOGICAL EFFECTS OF YOGA PRACTICE. WE MEASURED HEART RATE, BLOOD PRESSURE, THE HORMONES CORTISOL, PROLACTIN AND GROWTH HORMONE AND CERTAIN PSYCHOLOGICAL PARAMETERS IN A YOGA PRACTICING GROUP AND A CONTROL GROUP OF YOUNG FEMALE VOLUNTEERS READING IN A COMFORTABLE POSITION DURING THE EXPERIMENTAL PERIOD. THERE WERE NO SUBSTANTIAL DIFFERENCES BETWEEN THE GROUPS CONCERNING ENDOCRINE PARAMETERS AND BLOOD PRESSURE. THE COURSE OF HEART RATE WAS SIGNIFICANTLY DIFFERENT, THE YOGA GROUP HAD A DECREASE DURING THE YOGA PRACTICE. SIGNIFICANT DIFFERENCES BETWEEN BOTH GROUPS WERE FOUND IN PSYCHOLOGICAL PARAMETERS. IN THE PERSONALITY INVENTORY THE YOGA GROUP SHOWED MARKEDLY HIGHER SCORES IN LIFE SATISFACTION AND LOWER SCORES IN EXCITABILITY, AGGRESSIVENESS, OPENNESS, EMOTIONALITY AND SOMATIC COMPLAINTS. SIGNIFICANT DIFFERENCES COULD ALSO BE OBSERVED CONCERNING COPING WITH STRESS AND THE MOOD AT THE END OF THE EXPERIMENT. THE YOGA GROUP HAD SIGNIFICANT HIGHER SCORES IN HIGH SPIRITS AND EXTRAVERTEDNESS.	1994	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
15 1318  37 HEART RATE VARIABILITY IN CHRONIC LOW BACK PAIN PATIENTS RANDOMIZED TO YOGA OR STANDARD CARE. BACKGROUND: CHRONIC PAIN CAN ALTER THE AUTONOMIC BALANCE WITH INCREASED SYMPATHETIC ACTIVITY REFLECTED IN ALTERED HEART RATE VARIABILITY (HRV). IT HAS BEEN PROPOSED THAT YOGA CAN BE USEFUL TO CORRECT THE AUTONOMIC IMBALANCE IN PATIENTS WITH CHRONIC PAIN WHO HAVE REDUCED HRV. METHODS AND DESIGNS: IN THE PRESENT RANDOMIZED CONTROLLED TRIAL 62 PATIENTS WITH CHRONIC LOW BACK PAIN ASSOCIATED WITH ALTERED ALIGNMENT OF INTERVERTEBRAL DISCS (AGED BETWEEN 20 AND 45 YEARS, 32 MALES) WERE RANDOMIZED TO 2 GROUPS. ONE GROUP RECEIVED YOGA FOR 3 MONTHS WHILE THE OTHER GROUP CARRIED OUT STANDARD MEDICAL CARE BASED ON THE PHYSICIAN'S ADVICE. THE DURATION WAS THE SAME, I.E., 3 MONTHS. THE HEART RATE VARIABILITY AND RATE OF RESPIRATION WERE ASSESSED AT BASELINE AND AT THE END OF 3 MONTHS. RESULTS: THERE WAS A SIGNIFICANT DIFFERENCE IN THE BASELINE (PRE) VALUES BETWEEN GROUPS (P = 0.008) FOR RESPIRATION RATE WHICH WAS HIGHER IN THE YOGA GROUP. THE CHANGES REPORTED BELOW ARE PRE-POST COMPARISONS WITHIN EACH GROUP. THE YOGA GROUP SHOWED A SIGNIFICANT (P < 0.05; REPEATED MEASURES ANOVA, POST-HOC ANALYSES) DECREASE IN THE LF POWER OF HRV, RATE OF RESPIRATION AND A SIGNIFICANT INCREASE IN THE HF POWER OF HRV AND IN THE PNN50. CONCLUSION: THE RESULTS SUGGEST THAT YOGA PRACTICE CAN SHIFT THE AUTONOMIC BALANCE TOWARDS VAGAL DOMINANCE IN PATIENTS WITH CHRONIC LOW BACK PAIN ASSOCIATED WITH ALTERED ALIGNMENT OF INTERVERTEBRAL DISCS. TRIAL REGISTRATION: THE STUDY IS REGISTERED WITH THE CLINICAL TRIALS REGISTRY OF INDIA ( CTRI/2012/11/003094 ) AND CAN BE ACCESSED AT.	2016

THIS REPORT SHOWS THAT IN A GROUP OF 40 PHYSICAL EDUCATION TEACHERS WHO ALREADY HAD AN AVERAGE OF 8.9 YEARS PHYSICAL TRAINING, 3 MONTHS OF YOGIC TRAINING PRODUCED SIGNIFICANT IMPROVEMENT IN GENERAL HEALTH (IN TERMS OF BODY WEIGHT AND BP REDUCTION AND IMPROVED LUNG FUNCTIONS). 2. THERE WAS ALSO EVIDENCE OF DECREASED AUTONOMIC AROUSAL AND MORE OF PSYCHOPHYSIOLOGICAL RELAXATION (HEART RATE AND RESPIRATORY RATE REDUCTION), AND IMPROVED SOMATIC STEADINESS (DECREASED ERRORS IN THE STEADINESS TEST). 3. THE CHANGES AT THE END OF 3 MONTHS IN VOLAR GSR IN DIFFERENT DIRECTIONS (INCREASE/DECREASE/NO CHANGE), DEPENDING ON THE INITIAL VALUES, SUGGESTS THAT PRACTISING YOGA MAY HELP TO BRING ABOUT A BALANCE IN DIFFERENT AUTONOMIC FUNCTIONS, SO THAT FUNCTIONING IS OPTIMISED.	1993	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
17  523  29 COMPARISON OF CHANGES IN AUTONOMIC AND RESPIRATORY PARAMETERS OF GIRLS AFTER YOGA AND GAMES AT A COMMUNITY HOME. THE HEART RATE, BREATHING RATE, AND SKIN RESISTANCE WERE RECORDED FOR 20 COMMUNITY HOME GIRLS (HOME GROUP) AND FOR 20 AGE-MATCHED GIRLS FROM A REGULAR SCHOOL (SCHOOL GROUP). THE FORMER GROUP HAD A SIGNIFICANTLY HIGHER RATE OF BREATHING AND A MORE IRREGULAR BREATH PATTERN KNOWN TO CORRELATE WITH HIGH FEAR AND ANXIETY, THAN THE SCHOOL GROUP. SKIN RESISTANCE WAS SIGNIFICANTLY LOWER IN THE SCHOOL GROUP, WHICH MAY SUGGEST GREATER AROUSAL, 28 GIRLS OF THE HOME GROUP FORMED 14 PAIRS, MATCHED FOR AGE AND DURATION OF STAY IN THE HOME. SUBJECTS OF A PAIR WERE RANDOMLY ASSIGNED TO EITHER YOGA OR GAMES GROUPS. FOR THE FORMER EMPHASIS WAS ON RELAXATION AND AWARENESS, WHEREAS FOR THE LATTER INCREASING PHYSICAL ACTIVITY WAS EMPHASIZED. AT THE END OF AN HOUR DAILY FOR SIX MONTHS BOTH GROUPS SHOWED A SIGNIFICANT DECREASE IN THE RESTING HEART RATE RELATIVE TO INITIAL VALUES (WILCOXON PAIRED-SAMPLE REST), AND THE YOGA GROUP SHOWED A SIGNIFICANT DECREASE IN BREATH RATE, WHICH APPEARED MORE REGULAR BUT NO SIGNIFICANT INCREASE IN THE SKIN RESISTANCE. THESE RESULTS SUGGEST THAT A YOGA PROGRAM WHICH INCLUDES RELAXATION, AWARENESS, AND GRADED PHYSICAL ACTIVITY IS A USEFUL ADDITION TO THE ROUTINE OF COMMUNITY HOME CHILDREN.	1997	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
18 1637  30 MODULATION OF CARDIAC AUTONOMIC BALANCE WITH ADJUVANT YOGA THERAPY IN PATIENTS WITH REFRACTORY EPILEPSY. THE PRACTICE OF YOGA REGULATES BODY PHYSIOLOGY THROUGH CONTROL OF POSTURE, BREATHING, AND MEDITATION. EFFECTS OF YOGA ON AUTONOMIC FUNCTIONS OF PATIENTS WITH REFRACTORY EPILEPSY, AS QUANTIFIED BY STANDARDIZED AUTONOMIC FUNCTION TESTS (AFTS), WERE DETERMINED. THE YOGA GROUP (N=18) RECEIVED SUPERVISED TRAINING IN YOGA, AND THE EXERCISE GROUP (N=16) PRACTICED SIMPLE ROUTINE EXERCISES. AFTS WERE REPEATED AFTER 10 WEEKS OF DAILY SESSIONS. DATA WERE COMPARED WITH THOSE OF HEALTHY VOLUNTEERS (N=142). THE YOGA GROUP SHOWED SIGNIFICANT IMPROVEMENT IN PARASYMPATHETIC PARAMETERS AND A DECREASE IN SEIZURE FREQUENCY SCORES. THERE WAS NO IMPROVEMENT IN BLOOD PRESSURE PARAMETERS IN EITHER GROUP. TWO PATIENTS IN THE YOGA GROUP ACHIEVED NORMAL AUTONOMIC FUNCTIONS AT THE END OF 10 WEEKS OF THERAPY, WHEREAS THERE WERE NO CHANGES IN THE EXERCISE GROUP. THE DATA SUGGEST THAT YOGA MAY HAVE A ROLE AS AN ADJUVANT THERAPY IN THE MANAGEMENT OF AUTONOMIC DYSFUNCTION IN PATIENTS WITH REFRACTORY EPILEPSY.	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
19  760  33 EFFECT OF SUDARSANKRIYA YOGA PRACTICES ON P300 AMPLITUDE AND LATENCY. THE COGNITIVE ABILITY WHICH WAS PERCEIVED AS A CONSTANT TRAIT, IS NOW UNDERSTOOD TO BE UPGRADED BY ADAPTIVE AND EXTENDED TRAINING. YOGA PRACTICES ARE KNOWN TO SHARPEN THE INTELLECT AND ENHANCE CONCENTRATION. IN THE INITIAL PERIOD OF PRACTICING YOGA AS AN ALTERNATIVE/SUPPORTING TOOL TO MEDICAL LINE OF TREATMENT, IT IS ESSENTIAL TO INVESTIGATE EFFECT OF YOGA ON COGNITIVE ABILITY USING OBJECTIVE METHOD, IN ORDER TO ESTABLISH EVIDENCES. HENCE, AIM OF THIS STUDY WAS TO EXPLORE THE EFFECT OF REGULAR PRACTICE OF SUDARSANKRIYA YOGA ON AUDITORY EVENT RELATED POTENTIAL (P300) BY RECORDING AND COMPARING PEAK LATENCY AND AMPLITUDE. THE PARTICIPANTS WERE DIVIDED INTO THREE GROUPS WITH GROUP I AND GROUP II PARTICIPANTS PRACTICING SUDARSANKRIYA YOGA FOR MORE THAN 36 MONTHS AND LESS THAN 36 MONTHS RESPECTIVELY. GROUP III WERE NON-PRACTITIONERS WITH NO PRIOR PRACTICE OF ANY FORM OF YOGA. TWENTY PARTICIPANTS IN EACH GROUP WITH A TOTAL OF 60 PARTICIPANTS BETWEEN 40 TO 65 YEARS OF AGE WERE RECRUITED FOR THE STUDY. RESULTS REVEALED A SIGNIFICANT DIFFERENCE FOR MEAN LATENCY AND AMPLITUDE BETWEEN THREE GROUPS. FINDINGS OF THE CURRENT STUDY SUGGEST THAT SUDARSANKRIYA YOGA PRACTICES SLOWS DOWN THE PROCESS OF AGING EFFECT OR MAINTAINS ON COGNITIVE ABILITY IN ADULTS.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
20 1258  27 FIFTEEN MINUTES OF CHAIR-BASED YOGA POSTURES OR GUIDED MEDITATION PERFORMED IN THE OFFICE CAN ELICIT A RELAXATION RESPONSE. THIS STUDY COMPARED ACUTE (15 MIN) YOGA POSTURE AND GUIDED MEDITATION PRACTICE, PERFORMED SEATED IN A TYPICAL OFFICE WORKSPACE, ON PHYSIOLOGICAL AND PSYCHOLOGICAL MARKERS OF STRESS. TWENTY PARTICIPANTS (39.6 +/- 9.5 YR) COMPLETED THREE CONDITIONS: YOGA, MEDITATION, AND CONTROL (I.E., USUAL WORK) SEPARATED BY >/=24 HRS. YOGA AND MEDITATION SIGNIFICANTLY REDUCED PERCEIVED STRESS VERSUS CONTROL, AND THIS EFFECT WAS MAINTAINED POSTINTERVENTION. YOGA INCREASED HEART RATE WHILE MEDITATION REDUCED HEART RATE VERSUS CONTROL (P < 0.05). RESPIRATION RATE WAS REDUCED DURING YOGA AND MEDITATION VERSUS CONTROL (P < 0.05). DOMAINS OF HEART RATE VARIABILITY (E.G., SDNN AND TOTAL POWER) WERE SIGNIFICANTLY REDUCED DURING CONTROL VERSUS YOGA AND MEDITATION. SYSTOLIC AND DIASTOLIC BLOOD PRESSURE WERE REDUCED SECONDARY TO MEDITATION VERSUS CONTROL ONLY (P < 0.05). PHYSIOLOGICAL ADAPTATIONS GENERALLY REGRESSED TOWARD BASELINE POSTINTERVENTION. IN CONCLUSION, YOGA POSTURES OR MEDITATION PERFORMED IN THE OFFICE CAN ACUTELY IMPROVE SEVERAL PHYSIOLOGICAL AND PSYCHOLOGICAL MARKERS OF STRESS. THESE EFFECTS MAY BE AT LEAST PARTIALLY MEDIATED BY REDUCED RESPIRATION RATE.	2012
