1  341 195 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	

2 2736  45 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
3  427  50 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 1744  36 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
5  209  57 A SINGLE SESSION OF HATHA YOGA IMPROVES STRESS REACTIVITY AND RECOVERY AFTER AN ACUTE PSYCHOLOGICAL STRESS TASK-A COUNTERBALANCED, RANDOMIZED-CROSSOVER TRIAL IN HEALTHY INDIVIDUALS. OBJECTIVES: YOGA IS PROMOTED AS AN ANTI-STRESS ACTIVITY, HOWEVER, LITTLE IS KNOWN ABOUT THE MECHANISMS THROUGH WHICH IT ACTS. THE PRESENT STUDY INVESTIGATED THE ACUTE EFFECTS OF A HATHA YOGA SESSION, DISPLAYED ON A VIDEO, ON THE RESPONSE TO AND RECOVERY FROM AN ACUTE PSYCHOLOGICAL STRESSOR. METHODS: TWENTY-FOUR HEALTHY YOUNG ADULTS TOOK PART IN A COUNTERBALANCED, RANDOMIZED-CROSSOVER TRIAL, WITH A YOGA AND A CONTROL CONDITION (WATCHING TV). PARTICIPANTS ATTENDED THE LABORATORY IN THE AFTERNOON ON TWO DAYS AND EACH SESSION COMPRISED A BASELINE, CONTROL OR YOGA TASK, STRESS TASK AND RECOVERY. BLOOD PRESSURE (BP), HEART RATE (HR) AND SALIVARY CORTISOL RESPONSES WERE MEASURED. STATE COGNITIVE- AND SOMATIC-ANXIETY ALONG WITH SELF-CONFIDENCE WERE ASSESSED BEFORE AND AFTER THE STRESSOR. RESULTS: ALTHOUGH NO DIFFERENCE IN THE BP OR HR RESPONSES TO STRESS WERE FOUND BETWEEN CONDITIONS, SYSTOLIC BP (P=0.047) AND DIASTOLIC BP (P=0.018) RECOVERY FROM STRESS WERE SIGNIFICANTLY ACCELERATED AND SALIVARY CORTISOL REACTIVITY WAS SIGNIFICANTLY LOWER (P=0.01) IN THE YOGA CONDITION. A YOGA SESSION ALSO INCREASED SELF-CONFIDENCE (P=0.006) IN PREPARATION FOR THE TASK AND AFTER COMPLETION. MOREOVER, SELF-CONFIDENCE REPORTED AFTER THE STRESS TASK WAS CONSIDERED DEBILITATIVE TOWARDS PERFORMANCE IN THE CONTROL CONDITION, BUT REMAINED FACILITATIVE IN THE YOGA CONDITION. CONCLUSION: OUR RESULTS SHOW THAT A SINGLE VIDEO-INSTRUCTED SESSION OF HATHA YOGA WAS ABLE TO IMPROVE STRESS REACTIVITY AND RECOVERY FROM AN ACUTE STRESS TASK IN HEALTHY INDIVIDUALS. THESE POSITIVE PRELIMINARY FINDINGS ENCOURAGE FURTHER INVESTIGATION IN AT-RISK POPULATIONS IN WHICH THE MAGNITUDE OF EFFECTS MAY BE GREATER, AND SUPPORT THE USE OF YOGA FOR STRESS REACTIVITY AND RECOVERY.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
6 1424  25 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
7 2516  20 YOGA CLINICAL RESEARCH REVIEW. IN THIS PAPER RECENT RESEARCH IS REVIEWED ON THE EFFECTS OF YOGA POSES ON PSYCHOLOGICAL CONDITIONS INCLUDING ANXIETY AND DEPRESSION, ON PAIN SYNDROMES, CARDIOVASCULAR, AUTOIMMUNE AND IMMUNE CONDITIONS AND ON PREGNANCY. FURTHER, THE PHYSIOLOGICAL EFFECTS OF YOGA INCLUDING DECREASED HEARTRATE AND BLOOD PRESSURE AND THE PHYSICAL EFFECTS INCLUDING WEIGHT LOSS AND INCREASED MUSCLE STRENGTH ARE REVIEWED. FINALLY, POTENTIAL UNDERLYING MECHANISMS ARE PROPOSED INCLUDING THE STIMULATION OF PRESSURE RECEPTORS LEADING TO ENHANCED VAGAL ACTIVITY AND REDUCED CORTISOL. THE REDUCTION IN CORTISOL, IN TURN, MAY CONTRIBUTE TO POSITIVE EFFECTS SUCH AS ENHANCED IMMUNE FUNCTION AND A LOWER PREMATURITY RATE.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
8  297  38 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

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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
10 1512  36 IS THERE MORE TO YOGA THAN EXERCISE? CONTEXT: YOGA IS INCREASING IN POPULARITY, WITH AN ESTIMATED 15 MILLION PRACTITIONERS IN THE UNITED STATES, YET THERE IS A DEARTH OF EMPIRICAL DATA ADDRESSING THE HOLISTIC BENEFITS OF YOGA. OBJECTIVE: TO COMPARE THE PHYSICAL AND MENTAL BENEFITS OF AN EXERCISE-BASED YOGA PRACTICE TO THAT OF A MORE COMPREHENSIVE YOGA PRACTICE (ONE WITH AN ETHICAL/SPIRITUAL COMPONENT). DESIGN: STUDENTS WITH MILD TO MODERATE DEPRESSION, ANXIETY, OR STRESS AND WHO AGREED TO PARTICIPATE WERE ASSIGNED TO ONE OF THREE GROUPS: INTEGRATED YOGA, YOGA AS EXERCISE, CONTROL. PARTICIPANTS: A TOTAL OF 81 UNDERGRADUATE STUDENTS 18 YEARS AND OLDER AT A UNIVERSITY IN THE SOUTHEASTERN UNITED STATES PARTICIPATED IN THE STUDY. MAIN OUTCOME MEASURES: DEPRESSION, ANXIETY, STRESS, HOPE, AND SALIVARY CORTISOL. RESULTS: OVER TIME, PARTICIPANTS IN BOTH THE INTEGRATED AND EXERCISE YOGA GROUPS EXPERIENCED DECREASED DEPRESSION AND STRESS, AN INCREASED SENSE OF HOPEFULNESS, AND INCREASED FLEXIBILITY COMPARED TO THE CONTROL GROUP. HOWEVER, ONLY THE INTEGRATED YOGA GROUP EXPERIENCED DECREASED ANXIETY-RELATED SYMPTOMS AND DECREASED SALIVARY CORTISOL FROM THE BEGINNING TO THE END OF THE STUDY. CONCLUSIONS: YOGA, PRACTICED IN A MORE INTEGRATED FORM, IE, WITH AN ETHICAL AND SPIRITUAL COMPONENT, MAY PROVIDE ADDITIONAL BENEFITS OVER YOGA PRACTICED AS AN EXERCISE REGIMEN.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
11  569  19 DECREASE IN SERUM CORTISOL DURING YOGA EXERCISE IS CORRELATED WITH ALPHA WAVE ACTIVATION. WE EXAMINED CHANGES IN BRAIN WAVES AND BLOOD LEVELS OF SERUM CORTISOL DURING YOGA EXERCISE IN 7 YOGA INSTRUCTORS AND FOUND THAT ALPHA WAVES INCREASED AND SERUM CORTISOL DECREASED. THESE TWO MEASURES WERE NEGATIVELY CORRELATED (R = -.83).

12 1964  33 SEPARATING THE "LIMBS" OF YOGA: LIMITED EFFECTS ON STRESS AND MOOD. THOUGH MILLIONS OF PEOPLE PRACTICE YOGA TO REDUCE STRESS AND IMPROVE THEIR MOOD, IT IS UNCLEAR WHICH ASPECT OF YOGA IS RESPONSIBLE FOR THESE EFFECTS. TO INVESTIGATE RELEVANT ASPECTS, OR "LIMBS" OF YOGA, PARTICIPANTS WHO WERE NOVICES IN THE PRACTICE OF YOGA ENGAGED IN A SINGLE YOGA MANIPULATION (I.E., POSES, BREATH WORK, MEDITATION, OR LISTENING TO A LECTURE ABOUT YOGA) FOR 20 MIN BEFORE EXPERIENCING A MILD STRESSOR. PARTICIPANTS' HEART RATE, BLOOD PRESSURE, MOOD, AND ANXIETY LEVEL WERE ASSESSED, BOTH IMMEDIATELY AFTER THE YOGA MANIPULATION AND AFTER THE MILD STRESSOR. THE 20-MIN YOGA MANIPULATION DID NOT DIFFERENTIALLY AFFECT ANY OF THE MEASURES, INCLUDING PARTICIPANTS' STRESS RESPONSE AFTER THE MILD STRESSOR. RESULTS ARE DISCUSSED REGARDING THE INDIVIDUAL COMPONENTS OF A YOGA PRACTICE.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
13  314  35 AN IN-SITU INVESTIGATION OF THE ACUTE EFFECTS OF BIKRAM YOGA ON POSITIVE- AND NEGATIVE AFFECT, AND STATE-ANXIETY IN CONTEXT OF PERCEIVED STRESS. BACKGROUND: BIKRAM YOGA IS A RELATIVELY NEW, BUT AN INCREASINGLY POPULAR FORM OF EXERCISE. ITS HEALTH BENEFITS WERE DEMONSTRATED ON PHYSICAL AND PSYCHOLOGICAL MEASURES. AIMS: THE CURRENT FIELD STUDY TESTED THE ACUTE EFFECTS OF BIKRAM YOGA ON PRACTITIONERS' POSITIVE-/NEGATIVE-AFFECT AND STATE-ANXIETY, AND THEIR LINK TO THE SELF-PERCEIVED STRESS, IN BIKRAM YOGA PARTICIPANTS. METHOD: FIELD STUDY, WITHIN-PARTICIPANTS DESIGN, TESTING PERCEIVED STRESS AND ITS RELATION TO CHANGES IN POSITIVE-/NEGATIVE-AFFECT AND STATE-ANXIETY IN 53 HABITUAL BIKRAM YOGA PARTICIPANTS. RESULTS: STATISTICALLY SIGNIFICANT POSITIVE CHANGES EMERGED IN ALL THREE PSYCHOLOGICAL MEASURES AFTER THE 90-MIN BIKRAM YOGA SESSION. THE DECREASE IN NEGATIVE-AFFECT AND STATE-ANXIETY WERE SIGNIFICANTLY AND POSITIVELY RELATED TO THE PERCEIVED STRESS. ESTIMATED EFFORT WAS UNRELATED TO THE MAGNITUDE OF THE CHANGES RECORDED IN THE PSYCHOLOGICAL MEASURES. HEART RATES AND SELF-REPORT MEASURES INDICATED THAT PHYSICALLY BIKRAM YOGA IS ONLY MILDLY CHALLENGING. CONCLUSIONS: THE FINDINGS ILLUSTRATE THAT, INDEPENDENTLY OF THE PHYSICAL EFFORT, BIKRAM YOGA IS A NEW MILD FORM OF EXERCISE THAT REDUCES NEGATIVE-AFFECT AND STATE-ANXIETY, AND THE REDUCTION IS DIRECTLY RELATED TO THE PERCEIVED STRESS. THEREFORE, BIKRAM YOGA APPEARS TO BE BENEFICIAL FOR ALL PRACTITIONERS, BUT EVEN MORE SO FOR THE INDIVIDUALS WHO EXPERIENCE SUBSTANTIAL STRESS IN THE DAILY LIFE.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
14  452  36 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
15 2863  34 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
16  361  36 ASSOCIATIONS BETWEEN ATTENTION, AFFECT AND CARDIAC ACTIVITY IN A SINGLE YOGA SESSION FOR FEMALE CANCER SURVIVORS: AN ENACTIVE NEUROPHENOMENOLOGY-BASED APPROACH. YOGA PRACTICE IS REPORTED TO LEAD TO IMPROVEMENTS IN QUALITY OF LIFE, PSYCHOLOGICAL FUNCTIONING, AND SYMPTOM INDICES IN CANCER SURVIVORS. IMPORTANTLY, MEDITATIVE STATES EXPERIENCED WITHIN YOGA PRACTICE ARE CORRELATED TO NEUROPHYSIOLOGICAL SYSTEMS THAT MODERATE BOTH FOCUS OF ATTENTION AND AFFECTIVE VALENCE. THE CURRENT STUDY USED A MIXED METHODS APPROACH BASED IN NEUROPHENOMENOLOGY TO INVESTIGATE ASSOCIATIONS BETWEEN ATTENTION, AFFECT, AND CARDIAC ACTIVITY DURING A SINGLE YOGA SESSION FOR FEMALE CANCER SURVIVORS. YOGA PRACTICE WAS ASSOCIATED WITH A LINEAR INCREASE IN ASSOCIATIVE ATTENTION AND POSITIVE AFFECTIVE VALENCE, WHILE SHIFTS IN CARDIAC ACTIVITY WERE RELATED TO THE INTENSITY OF EACH YOGA SEQUENCE. CHANGES IN ATTENTION AND AFFECT WERE PREDICTED BY CONCURRENTLY ASSESSED CARDIAC ACTIVITY. AWARENESS OF BREATHING, PHYSICAL MOVEMENT, AND INCREASED RELAXATION WERE REPORTED BY PARTICIPANTS AS POTENTIAL MECHANISMS FOR YOGA'S SALUTARY EFFECTS. WHILE YOGA PRACTICE SHARES COMMONALITIES WITH EXERCISE AND RELAXATION TRAINING, YOGA MAY SERVE PRIMARILY AS A PROMISING MEDITATIVE ATTENTION-AFFECT REGULATION TRAINING METHODOLOGY.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
17 1258  36 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
18 2043  36 THE ACUTE EFFECTS OF VINYASA FLOW YOGA ON VASCULAR FUNCTION, LIPID AND GLUCOSE CONCENTRATIONS, AND MOOD. WHILE THE CHRONIC EFFECTS OF CERTAIN STYLES OF YOGA ON CARDIOMETABOLIC FACTORS HAVE BEEN INVESTIGATED, LITTLE IS KNOWN ABOUT THE ACUTE EFFECTS OF A SINGLE YOGA SESSION ON THESE OUTCOMES. MOREOVER, VINYASA YOGA'S POTENTIAL TO MODULATE CARDIOMETABOLIC OUTCOMES HAS NOT BEEN ESTABLISHED. THE PURPOSE OF THIS STUDY IS TO DETERMINE THE ACUTE EFFECTS OF A VINYASA YOGA SESSION ON ARTERIAL STIFFNESS, WAVE REFLECTION, LIPID AND GLUCOSE CONCENTRATIONS, AND MOOD IN ADULTS WITH PRIOR YOGA EXPERIENCE. THIRTY YOGA PRACTITIONERS WITH A MINIMUM OF 3 MONTHS OF PRACTICE EXPERIENCE WERE ENROLLED INTO THE STUDY. CAROTID-FEMORAL PULSE WAVE VELOCITY (CF-PWV), AUGMENTATION INDEX (AIX), LIPID PROFILE, GLUCOSE CONCENTRATIONS, AND MOOD (POSITIVE AND NEGATIVE AFFECT SCALE) WERE ASSESSED AT BASELINE AND IMMEDIATELY FOLLOWING A 1 -H VINYASA YOGA SESSION. AFTER THE YOGA SESSION, PARTICIPANTS HAD SIGNIFICANTLY LOWER AIX (P < 0.001), NON-HDL CHOLESTEROL (P < 0.05), AND NEGATIVE AFFECT (P < 0.01) COMPARED TO BASELINE. THESE RESULTS HIGHLIGHT THE EFFICACY OF A SINGLE BOUT OF YOGA IN ALTERING WAVE REFLECTION WHILE IMPROVING MOOD AND LIPID CONCENTRATIONS IN HEALTHY ADULTS WITH A HISTORY OF YOGA PRACTICE.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
19 1745  27 PHYSIOLOGICAL CHANGES IN SPORTS TEACHERS FOLLOWING 3 MONTHS OF TRAINING IN YOGA. 1. 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
20  716  42 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
