1 2334 131 TWELVE-WEEK YOGA VS. AEROBIC CYCLING INITIATION IN SEDENTARY HEALTHY SUBJECTS: A BEHAVIORAL AND MULTIPARAMETRIC INTERVENTIONAL PET/MR STUDY. INTERVENTIONAL YOGA STUDIES WITH AN ACTIVE CONTROL GROUP REMAIN SCARCE AND ARE IMPORTANT TO CLARIFY THE UNDERLYING NEUROBIOLOGY. WE CONDUCTED AN INTERVENTIONAL STUDY IN HEALTHY CONTROLS USING SIMULTANEOUS POSITRON EMISSION TOMOGRAPHY/MAGNETIC RESONANCE (PET/MR) IMAGING AND PSYCHOMETRIC SCALES. THIRTY HEALTHY, FEMALE VOLUNTEERS (28.4 +/- 8.4 YEARS) PARTICIPATED AND WERE RANDOMLY ASSIGNED TO A 12-WEEK YOGA OR INDOOR CYCLING INTERVENTION. BEFORE AND AFTER THE INTERVENTION, [(18)F]FDG AND [(11)C]UCB-J PET WAS PERFORMED ON A SIMULTANEOUS GE SIGNA PET/MR WITH VOLUMETRIC IMAGING. PSYCHOMETRIC SCALES WERE EVALUATED ON AFFECT, MINDFULNESS, STRESS, WORRYING, SELF-COMPASSION, AND INTEROCEPTIVE AWARENESS. YOGA SUBJECTS SCORED HIGHER ON INTEROCEPTIVE AWARENESS COMPARED TO BASELINE (P < 0.001). COGNITIVE (P = 0.009) AND OVERALL COGNITIVE FUNCTIONING (P = 0.01) IMPROVED AFTER THE YOGA INTERVENTION COMPARED TO THE CYCLING GROUP. WE DID NOT OBSERVE SIGNIFICANT DIFFERENCES IN GLUCOSE METABOLISM, SYNAPTIC DENSITY, OR GRAY MATTER (GM) VOLUME. THE INDOOR CYCLING GROUP DID NOT SHOW CHANGES IN PSYCHOMETRIC VARIABLES, BUT SIGNIFICANT INCREASES IN RELATIVE GLUCOSE METABOLISM WERE OBSERVED IN THE PARAHIPPOCAMPAL/FUSIFORM GYRUS AND CEREBELLUM (P < 0.001). IN CONCLUSION, 12 WEEKS OF YOGA PRACTICE HAS SIGNIFICANT EFFECTS ON INTEROCEPTIVE AWARENESS AND PERCEIVED COGNITIVE FUNCTION IN STARTERS. LONGER INTERVENTIONS AND/OR HIGHER FREQUENCY OF YOGA PRACTICE MAY BE NEEDED TO DETECT CEREBRAL METABOLIC AND/OR MORPHOLOGIC EFFECTS ON THE MACROSCOPIC LEVEL.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
2 1555  47 LONG-TERM ASHTANGA YOGA PRACTICE DECREASES MEDIAL TEMPORAL AND BRAINSTEM GLUCOSE METABOLISM IN RELATION TO YEARS OF EXPERIENCE. BACKGROUND: YOGA IS INCREASINGLY POPULAR WORLDWIDE WITH SEVERAL PHYSICAL AND MENTAL BENEFITS, BUT THE UNDERLYING NEUROBIOLOGY REMAINS UNCLEAR. WHEREAS MANY STUDIES HAVE FOCUSED ON PURE MEDITATIONAL ASPECTS, THE TRIAD OF YOGA INCLUDES MEDITATION, POSTURES, AND BREATHING. WE CONDUCTED A CROSS-SECTIONAL STUDY COMPARING EXPERIENCED YOGA PRACTITIONERS TO YOGA-NAIVE HEALTHY SUBJECTS USING A MULTIPARAMETRIC 2 X 2 DESIGN WITH SIMULTANEOUS POSITRON EMISSION TOMOGRAPHY/MAGNETIC RESONANCE (PET/MR) IMAGING. METHODS: (18)F-FDG PET, MORPHOMETRIC AND DIFFUSION TENSOR IMAGING, RESTING STATE FMRI, AND MR SPECTROSCOPY WERE ACQUIRED IN 10 EXPERIENCED (4.8 +/- 2.3 YEARS OF REGULAR YOGA EXPERIENCE) YOGA PRACTITIONERS AND 15 MATCHED CONTROLS IN REST AND AFTER A SINGLE PRACTICE (YOGA PRACTICE AND PHYSICAL EXERCISE, RESPECTIVELY). RESULTS: IN REST, DECREASED REGIONAL GLUCOSE METABOLISM IN THE MEDIAL TEMPORAL CORTEX, STRIATUM, AND BRAINSTEM WAS OBSERVED IN YOGA PRACTITIONERS COMPARED TO CONTROLS (P < 0.0001), WITH A SIGNIFICANT INVERSE CORRELATION OF RESTING PARAHIPPOCAMPAL AND BRAINSTEM METABOLISM WITH YEARS OF REGULAR YOGA PRACTICE (RHO < - 0.63, P < 0.05). A SINGLE YOGA PRACTICE RESULTED IN SIGNIFICANT HYPERMETABOLISM IN THE CEREBELLUM (P < 0.0001). NONE OF THE MR MEASURES DIFFERED, BOTH AT REST AND AFTER INTERVENTION. CONCLUSIONS: EXPERIENCED YOGA PRACTITIONERS SHOW REGIONAL LONG-TERM DECREASES IN GLUCOSE METABOLISM RELATED TO YEARS OF PRACTICE. TO ELUCIDATE A POTENTIAL CAUSALITY, A PROSPECTIVE LONGITUDINAL STUDY IN YOGA-NAIVE INDIVIDUALS IS WARRANTED.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
3 2693  30 YOGA INCREASES THE VOLUME OF THE HIPPOCAMPUS IN ELDERLY SUBJECTS. CONTEXT: THE NEUROBIOLOGICAL EFFECT OF YOGA ON THE CORTICAL STRUCTURES IN THE ELDERLY IS AS YET UNKNOWN. MATERIALS AND METHODS: SEVEN HEALTHY ELDERLY SUBJECTS RECEIVED YOGA INTERVENTION AS AN ADD-ON LIFE-STYLE PRACTICE. MAGNETIC RESONANCE IMAGING SCANS WERE OBTAINED BEFORE AND 6 MONTHS LATER. VOXEL-BASED-MORPHOMETRIC ANALYSES COMPARED THE BRAINS BEFORE AND AFTER THE YOGA. RESULTS: YOGA GROUP WAS FOUND TO HAVE INCREASES IN HIPPOCAMPAL, BUT NOT IN OCCIPITAL GRAY MATTER. CONCLUSION: YOGA HAS POTENTIAL TO REDUCE NEURO-SENESCENCE. SMALL SAMPLE SIZE AND ABSENCE OF THE CONTROL GROUP PREVENT GENERALIZATION OF THE FINDINGS LIMITING ITS TRANSLATIONAL VALUE.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
4 2043  29 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
5 1972  35 SHORT-TERM SAHAJA YOGA MEDITATION TRAINING MODULATES BRAIN STRUCTURE AND SPONTANEOUS ACTIVITY IN THE EXECUTIVE CONTROL NETWORK. INTRODUCTION: WHILE CROSS-SECTIONAL STUDIES HAVE SHOWN NEURAL CHANGES IN LONG-TERM MEDITATORS, THEY MIGHT BE CONFOUNDED BY SELF-SELECTION AND POTENTIAL BASELINE DIFFERENCES BETWEEN MEDITATORS AND NON MEDITATORS. PROSPECTIVE LONGITUDINAL STUDIES OF THE EFFECTS OF MEDITATION IN NAIVE SUBJECTS ARE MORE CONCLUSIVE WITH RESPECT TO CAUSAL INFERENCES, BUT RELATED EVIDENCE IS SO FAR LIMITED. METHODS: HERE, WE ASSESSED THE EFFECTS OF A 4-WEEK SAHAJA YOGA MEDITATION TRAINING ON GRAY MATTER DENSITY AND SPONTANEOUS RESTING-STATE BRAIN ACTIVITY IN A GROUP OF 12 MEDITATION-NAIVE HEALTHY ADULTS. RESULTS: COMPARED WITH 30 CONTROL SUBJECTS, THE PARTICIPANTS TO MEDITATION TRAINING SHOWED INCREASED GRAY MATTER DENSITY AND CHANGES IN THE COHERENCE OF INTRINSIC BRAIN ACTIVITY IN TWO ADJACENT REGIONS OF THE RIGHT INFERIOR FRONTAL GYRUS ENCOMPASSING THE ANTERIOR COMPONENT OF THE EXECUTIVE CONTROL NETWORK. BOTH THESE MEASURES CORRELATED WITH SELF-REPORTED WELL-BEING SCORES IN THE MEDITATION GROUP. CONCLUSIONS: THE SIGNIFICANT IMPACT OF A BRIEF MEDITATION TRAINING ON BRAIN REGIONS ASSOCIATED WITH ATTENTION, SELF-CONTROL, AND SELF-AWARENESS MAY REFLECT THE ENGAGEMENT OF COGNITIVE CONTROL SKILLS IN SEARCHING FOR A STATE OF MENTAL SILENCE, A DISTINCTIVE FEATURE OF SAHAJA YOGA MEDITATION. THE MANIFOLD IMPLICATIONS OF THESE FINDINGS INVOLVE BOTH MANAGERIAL AND REHABILITATIVE SETTINGS CONCERNED WITH WELL-BEING AND EMOTIONAL STATE IN NORMAL AND PATHOLOGICAL CONDITIONS.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
6  277  29 ADDITIONAL PRACTICE OF YOGA BREATHING WITH INTERMITTENT BREATH HOLDING ENHANCES PSYCHOLOGICAL FUNCTIONS IN YOGA PRACTITIONERS: A RANDOMIZED CONTROLLED TRIAL. BACKGROUND AND OBJECTIVE: THE PRACTICE OF YOGA IS ASSOCIATED WITH ENHANCED PSYCHOLOGICAL WELLBEING. THE CURRENT STUDY ASSESSED THE CORRELATION BETWEEN THE DURATION OF YOGA PRACTICE WITH STATE MINDFULNESS, MIND-WANDERING AND STATE ANXIETY. ALSO, WE EXAMINED IF AN ADDITIONAL 20 MIN OF YOGA BREATHING WITH INTERMITTENT BREATH HOLDING (EXPERIMENTAL GROUP) FOR 8 WEEKS WOULD AFFECT THESE PSYCHOLOGICAL VARIABLES MORE THAN REGULAR YOGA PRACTICE (CONTROL GROUP) ALONE. METHODS: ONE HUNDRED SIXTEEN SUBJECTS WERE RANDOMLY ASSIGNED TO EXPERIMENTAL (N = 60) AND CONTROL (N = 56) GROUPS. STATE MINDFULNESS ATTENTION AWARENESS SCALE (SMAAS), MIND-WANDERING QUESTIONNAIRE (MWQ) AND STATE ANXIETY INVENTORY WERE ADMINISTERED AT BASELINE AND AT THE END OF 8 WEEKS. RESULTS: BASELINE ASSESSMENT REVEALED A POSITIVE CORRELATION BETWEEN DURATION OF YOGA PRACTICE WITH SMAAS SCORES AND NEGATIVE CORRELATION WITH MWQ AND STATE ANXIETY SCORES. AT THE END OF 8 WEEKS, BOTH GROUPS DEMONSTRATED ENHANCED PSYCHOLOGICAL FUNCTIONS, BUT THE EXPERIMENTAL GROUP RECEIVING ADDITIONAL YOGA BREATHING PERFORMED BETTER THAN THE GROUP PRACTICING YOGA ALONE. CONCLUSION: AN ADDITIONAL PRACTICE OF YOGA BREATHING WITH INTERMITTENT BREATH HOLDING WAS FOUND TO ENHANCE THE PSYCHOLOGICAL FUNCTIONS IN YOUNG ADULT YOGA PRACTITIONERS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
7  447  28 CHANGED PATTERN OF REGIONAL GLUCOSE METABOLISM DURING YOGA MEDITATIVE RELAXATION. USING POSITRON EMISSION TOMOGRAPHY (PET), MEASUREMENTS OF THE REGIONAL CEREBRAL METABOLIC RATE OF GLUCOSE (RCMRGLC) ARE ABLE TO DELINEATE CEREBRAL METABOLIC RESPONSES TO EXTERNAL OR MENTAL STIMULATION. IN ORDER TO EXAMINE POSSIBLE CHANGES OF BRAIN METABOLISM DUE TO YOGA MEDITATION PET SCANS WERE PERFORMED IN 8 MEMBERS OF A YOGA MEDITATION GROUP DURING THE NORMAL CONTROL STATE (C) AND YOGA MEDITATIVE RELAXATION (YMR). WHEREAS THERE WERE INTRAINDIVIDUAL CHANGES OF THE TOTAL CMRGLC, THE ALTERATIONS WERE NOT SIGNIFICANT FOR INTERGROUP COMPARISON; SPECIFIC FOCAL CHANGES OR CHANGES IN THE INTERHEMISPHERIC DIFFERENCES IN METABOLISM WERE ALSO NOT SEEN; HOWEVER THE RATIOS OF FRONTAL VS. OCCIPITAL RCMRGLC WERE SIGNIFICANTLY ELEVATED (P LESS THAN 0.05) DURING YMR. THESE ALTERED RATIOS WERE CAUSED BY A SLIGHT INCREASE OF FRONTAL RCMRGLC AND A MORE PRONOUNCED REDUCTION IN PRIMARY AND SECONDARY VISUAL CENTERS. THESE DATA INDICATE A HOLISTIC BEHAVIOR OF THE BRAIN METABOLISM DURING THE TIME OF ALTERED STATE OF CONSCIOUSNESS DURING YMR.	1990	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
8 2449  22 YOGA AND THE INTERPLAY BETWEEN ATTENTIONAL LOAD AND EMOTION INTERFERENCE. THIS STUDY COMPARED 45 YOGA PRACTITIONERS (M AGE = 29.7 YR., SD = 6.4) AND 45 MATCHED CONTROLS (M AGE = 29.3 YR., SD = 6.2) ON THE PERFORMANCE OF A BEHAVIORAL TASK THAT ASSESSED NEGATIVE EMOTION INTERFERENCE DURING A HIGH- AND A LOW-ATTENTIONAL DEMAND CONDITION, AS WELL AS ON STATE AND TRAIT ANXIETY SCORES. OUTCOMES WERE ALSO COMPARED BETWEEN BEGINNER AND ADVANCED PRACTITIONERS. FOR THE BEHAVIORAL TASK, THE FINAL SAMPLE COMPRISED 36 YOGA AND 38 CONTROL PARTICIPANTS. THE YOGA GROUP PRESENTED LOWER EMOTION INTERFERENCE IN THE HIGH ATTENTIONAL CONDITION, COMPARED TO THE LOW ATTENTIONAL CONDITION; RATED EMOTIONAL IMAGES AS LESS UNPLEASANT, COMPARED TO CONTROLS; AND REPORTED LOWER STATE AND TRAIT ANXIETY SCORES RELATIVE TO CONTROLS. ALSO, EMOTION INTERFERENCE IN THE LOW ATTENTIONAL CONDITION WAS LOWER AMONG ADVANCED PRACTITIONERS AND STATE ANXIETY WAS LOWER AMONG PRACTITIONERS ATTENDING MORE THAN TWO WEEKLY YOGA CLASSES. THE RESULTS SUGGESTED THAT YOGA MAY HELP IMPROVE SELF-REGULATORY SKILLS AND LOWER ANXIETY. THE PSYCHOLOGICAL MECHANISMS UNDERLYING THE RELATIONSHIP BETWEEN YOGA AND EMOTION REGULATION SHOULD BE FURTHER INVESTIGATED IN LONGITUDINAL STUDIES.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
9  716  32 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
10 1288  32 GREATER CORTICAL THICKNESS IN ELDERLY FEMALE YOGA PRACTITIONERS-A CROSS-SECTIONAL STUDY. YOGA, A MIND-BODY ACTIVITY THAT REQUIRES ATTENTIONAL ENGAGEMENT, HAS BEEN ASSOCIATED WITH POSITIVE CHANGES IN BRAIN STRUCTURE AND FUNCTION, ESPECIALLY IN AREAS RELATED TO AWARENESS, ATTENTION, EXECUTIVE FUNCTIONS AND MEMORY. NORMAL AGING, ON THE OTHER HAND, HAS ALSO BEEN ASSOCIATED WITH STRUCTURAL AND FUNCTIONAL BRAIN CHANGES, BUT THESE GENERALLY INVOLVE DECREASED COGNITIVE FUNCTIONS. THE AIM OF THIS CROSS-SECTIONAL STUDY WAS TO COMPARE BRAIN CORTICAL THICKNESS (CT) IN ELDERLY YOGA PRACTITIONERS AND A GROUP OF AGE-MATCHED HEALTHY NON-PRACTITIONERS. WE TESTED 21 OLDER WOMEN WHO HAD PRACTICED HATHA YOGA FOR AT LEAST 8 YEARS AND 21 WOMEN NAIVE TO YOGA, MEDITATION OR ANY MIND-BODY INTERVENTIONS WHO WERE MATCHED TO THE FIRST GROUP IN AGE, YEARS OF FORMAL EDUCATION AND PHYSICAL ACTIVITY LEVEL. A T1-WEIGHTED MPRAGE SEQUENCE WAS ACQUIRED FOR EACH PARTICIPANT. YOGA PRACTITIONERS SHOWED SIGNIFICANTLY GREATER CT IN A LEFT PREFRONTAL LOBE CLUSTER, WHICH INCLUDED PORTIONS OF THE LATERAL MIDDLE FRONTAL GYRUS, ANTERIOR SUPERIOR FRONTAL GYRUS AND DORSAL SUPERIOR FRONTAL GYRUS. WE FOUND GREATER CT IN THE LEFT PREFRONTAL CORTEX OF HEALTHY ELDERLY WOMEN WHO TRAINED YOGA FOR A MINIMUM OF 8 YEARS COMPARED WITH WOMEN IN THE CONTROL GROUP.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
11 2085  31 THE EFFECT OF LONG TERM COMBINED YOGA PRACTICE ON THE BASAL METABOLIC RATE OF HEALTHY ADULTS. BACKGROUND: DIFFERENT PROCEDURES PRACTICED IN YOGA HAVE STIMULATORY OR INHIBITORY EFFECTS ON THE BASAL METABOLIC RATE WHEN STUDIED ACUTELY. IN DAILY LIFE HOWEVER, THESE PROCEDURES ARE USUALLY PRACTICED IN COMBINATION. THE PURPOSE OF THE PRESENT STUDY WAS TO INVESTIGATE THE NET CHANGE IN THE BASAL METABOLIC RATE (BMR) OF INDIVIDUALS ACTIVELY ENGAGING IN A COMBINATION OF YOGA PRACTICES (ASANA OR YOGIC POSTURES, MEDITATION AND PRANAYAMA OR BREATHING EXERCISES) FOR A MINIMUM PERIOD OF SIX MONTHS, AT A RESIDENTIAL YOGA EDUCATION AND RESEARCH CENTER AT BANGALORE. METHODS: THE MEASURED BMR OF INDIVIDUALS PRACTICING YOGA THROUGH A COMBINATION OF PRACTICES WAS COMPARED WITH THAT OF CONTROL SUBJECTS WHO DID NOT PRACTICE YOGA BUT LED SIMILAR LIFESTYLES. RESULTS: THE BMR OF THE YOGA PRACTITIONERS WAS SIGNIFICANTLY LOWER THAN THAT OF THE NON-YOGA GROUP, AND WAS LOWER BY ABOUT 13 % WHEN ADJUSTED FOR BODY WEIGHT (P < 0.001). THIS DIFFERENCE PERSISTED WHEN THE GROUPS WERE STRATIFIED BY GENDER; HOWEVER, THE DIFFERENCE IN BMR ADJUSTED FOR BODY WEIGHT WAS GREATER IN WOMEN THAN MEN (ABOUT 8 AND 18% RESPECTIVELY). IN ADDITION, THE MEAN BMR OF THE YOGA GROUP WAS SIGNIFICANTLY LOWER THAN THEIR PREDICTED VALUES, WHILE THE MEAN BMR OF NON-YOGA GROUP WAS COMPARABLE WITH THEIR PREDICTED VALUES DERIVED FROM 1985 WHO/FAO/UNU PREDICTIVE EQUATIONS. CONCLUSION: THIS STUDY SHOWS THAT THERE IS A SIGNIFICANTLY REDUCED BMR, PROBABLY LINKED TO REDUCED AROUSAL, WITH THE LONG TERM PRACTICE OF YOGA USING A COMBINATION OF STIMULATORY AND INHIBITORY YOGIC PRACTICES.	2006	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
12  629  37 DIFFERENCES IN BRAIN STRUCTURE AND FUNCTION AMONG YOGA PRACTITIONERS AND CONTROLS. BACKGROUND: YOGA IS A MIND-BODY BASED PHYSICAL ACTIVITY THAT HAS DEMONSTRATED A VARIETY OF PHYSIOLOGICAL, PSYCHOLOGICAL AND COGNITIVE HEALTH BENEFITS. ALTHOUGH YOGA PRACTICE HAS SHOWN TO IMPROVE COGNITIVE PERFORMANCE, FEW STUDIES HAVE EXAMINED THE UNDERLYING NEUROLOGICAL CORRELATES. OBJECTIVE: THE CURRENT STUDY AIMED TO DETERMINE THE DIFFERENCES IN GRAY MATTER VOLUME OF THE HIPPOCAMPUS, THALAMUS AND CAUDATE NUCLEUS AND BRAIN ACTIVATION DURING THE STERNBERG WORKING MEMORY TASK. METHOD: PARTICIPANTS WERE 13 EXPERIENCED YOGA PRACTITIONERS (MEAN AGE = 35.8), DEFINED AS HAVING MORE THAN 3 YEARS OF REGULAR YOGA PRACTICE, AND 13 AGE- AND SEX-MATCHED CONTROLS (MEAN AGE = 35.7). ALL PARTICIPANTS COMPLETED A 6-MIN WALK TEST TO ASSESS FITNESS, PSYCHOSOCIAL AND DEMOGRAPHIC QUESTIONNAIRES; AND UNDERWENT MAGNETIC RESONANCE IMAGING TO ASSESS GRAY MATTER VOLUME AND BRAIN ACTIVATION. RESULTS: THERE WERE NO GROUP DIFFERENCES ON DEMOGRAPHIC MEASURES OF INCOME, EDUCATION AND ON ESTIMATED VO2MAX OR PHYSICAL ACTIVITY LEVELS. GRAY MATTER VOLUME DIFFERENCES WERE OBSERVED IN THE LEFT HIPPOCAMPUS, SHOWING GREATER VOLUME IN EXPERIENCED YOGA PRACTITIONERS COMPARED TO CONTROLS (P = 0.017). THE FUNCTIONAL MRI RESULTS REVEALED LESS ACTIVATION IN THE DORSOLATERAL PREFRONTAL CORTEX IN YOGA PRACTITIONERS COMPARED TO CONTROLS DURING THE ENCODING PHASE OF THE STERNBERG TASK (P < 0.05). REACTION TIME AND ACCURACY ON THE TASK DID NOT DIFFER BETWEEN THE GROUPS. CONCLUSIONS: OUR RESULTS SUGGEST AN ASSOCIATION BETWEEN REGULAR LONG-TERM YOGA PRACTICE AND DIFFERENTIAL STRUCTURE AND FUNCTION OF SPECIFIC BRAIN REGIONS INVOLVED IN EXECUTIVE FUNCTION, SPECIFICALLY WORKING MEMORY, WHICH HAS PREVIOUSLY SHOWN TO IMPROVE WITH YOGA PRACTICE. FUTURE STUDIES NEED TO EXAMINE INTERVENTION EFFECTS OF YOGA AND EXPLORE ITS POTENTIAL TO MAINTAIN AND IMPROVE COGNITIVE HEALTH ACROSS THE LIFESPAN THROUGH LONGITUDINAL AND INTERVENTION STUDIES.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
13 1304  37 HATHA YOGA PRACTICE IMPROVES ATTENTION AND PROCESSING SPEED IN OLDER ADULTS: RESULTS FROM AN 8-WEEK RANDOMIZED CONTROL TRIAL. BACKGROUND: AGE-RELATED COGNITIVE DECLINE IS WELL DOCUMENTED ACROSS VARIOUS ASPECTS OF COGNITIVE FUNCTION, INCLUDING ATTENTION AND PROCESSING SPEED, AND LIFESTYLE BEHAVIORS SUCH AS PHYSICAL ACTIVITY PLAY AN IMPORTANT ROLE IN PREVENTING COGNITIVE DECLINE AND MAINTAINING OR EVEN IMPROVING COGNITIVE FUNCTION. PURPOSE: THE PURPOSE OF THIS STUDY WAS TO EVALUATE THE EFFECTS OF AN 8-WEEK HATHA YOGA INTERVENTION ON ATTENTION AND PROCESSING SPEED AMONG OLDER ADULTS. METHODS: PARTICIPANTS (N = 118; MEAN AGE, 62 +/- 5.59) WERE RANDOMLY ASSIGNED TO AN 8-WEEK HATHA YOGA GROUP OR A STRETCHING CONTROL GROUP AND COMPLETED COGNITIVE ASSESSMENTS-ATTENTION NETWORK TASK, TRAIL MAKING TEST PARTS A AND B, AND PATTERN COMPARISON TEST-AT BASELINE AND AFTER THE 8-WEEK INTERVENTION. RESULTS: ANALYSES OF COVARIANCE REVEALED SIGNIFICANTLY FASTER REACTION TIMES FOR THE YOGA GROUP ON THE ATTENTION NETWORK TASK'S NEUTRAL, CONGRUENT, AND INCONGRUENT CONDITIONS (P </= 0.04). THE YOGA INTERVENTION ALSO IMPROVED PARTICIPANTS' VISUOSPATIAL AND PERCEPTUAL PROCESSING ON THE TRAIL MAKING TEST PART B (P = 0.002) AND PATTERN COMPARISON (P < 0.001) TESTS. CONCLUSIONS: THESE RESULTS SUGGEST THAT YOGA PRACTICE THAT INCLUDES POSTURES, BREATHING, AND MEDITATIVE EXERCISES LEAD TO IMPROVED ATTENTIONAL AND INFORMATION PROCESSING ABILITIES. ALTHOUGH THE UNDERLYING MECHANISMS REMAIN LARGELY SPECULATIVE, MORE SYSTEMATIC TRIALS ARE NEEDED TO EXPLORE THE EXTENT OF COGNITIVE BENEFITS AND THEIR NEUROBIOLOGICAL MECHANISMS.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
14 1744  25 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 2371  32 WHAT HAS NEUROIMAGING TAUGHT US ON THE NEUROBIOLOGY OF YOGA? A REVIEW. YOGA IS BECOMING INCREASINGLY POPULAR WORLDWIDE, WITH SEVERAL IMPLICATED PHYSICAL AND MENTAL BENEFITS. HERE WE PROVIDE A COMPREHENSIVE AND CRITICAL REVIEW OF THE RESEARCH GENERATED FROM THE EXISTING NEUROIMAGING LITERATURE IN STUDIES OF YOGA PRACTITIONERS. WE REVIEWED 34 INTERNATIONAL PEER-REVIEWED NEUROIMAGING STUDIES OF YOGA USING MAGNETIC RESONANCE IMAGING (MRI), POSITRON EMISSION TOMOGRAPHY (PET), OR SINGLE-PHOTON EMISSION COMPUTED TOMOGRAPHY (SPECT): 11 MORPHOLOGICAL AND 26 FUNCTIONAL STUDIES, INCLUDING THREE STUDIES THAT WERE CLASSIFIED AS BOTH MORPHOLOGICAL AND FUNCTIONAL. CONSISTENT FINDINGS INCLUDE INCREASED GRAY MATTER VOLUME IN THE INSULA AND HIPPOCAMPUS, INCREASED ACTIVATION OF PREFRONTAL CORTICAL REGIONS, AND FUNCTIONAL CONNECTIVITY CHANGES MAINLY WITHIN THE DEFAULT MODE NETWORK. THERE IS QUITE SOME VARIABILITY IN THE NEUROIMAGING FINDINGS THAT PARTIALLY REFLECTS DIFFERENT YOGA STYLES AND APPROACHES, AS WELL AS SAMPLE SIZE LIMITATIONS. DIRECT COMPARATOR GROUPS SUCH AS PHYSICAL ACTIVITY ARE SCARCELY USED SO FAR. FINALLY, HYPOTHESES ON THE UNDERLYING NEUROBIOLOGY DERIVED FROM THE IMAGING FINDINGS ARE DISCUSSED IN THE LIGHT OF THE POTENTIAL BENEFICIAL EFFECTS OF YOGA.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
16 1473  31 INSULIN SENSITIVITY AND CARDIAC AUTONOMIC FUNCTION IN YOUNG MALE PRACTITIONERS OF YOGA. BACKGROUND: WHILE YOGA IS THOUGHT TO REDUCE THE RISK OF CHRONIC NON-COMMUNICABLE DISEASES SUCH AS DIABETES, THERE ARE NO STUDIES ON INSULIN SENSITIVITY IN LONG TERM PRACTITIONERS OF YOGA. WE ASSESSED INSULIN SENSITIVITY AND CARDIAC AUTONOMIC FUNCTION IN LONG TERM PRACTITIONERS OF YOGA. METHODS: FIFTEEN HEALTHY, YOUNG, MALE PRACTITIONERS OF YOGA WERE COMPARED WITH 15 YOUNG, HEALTHY MALES WHO DID NOT PRACTICE YOGA MATCHED FOR BODY-MASS INDEX. FASTING INSULIN SENSITIVITY WAS MEASURED IN THE FASTING STATE BY THE HYPERINSULINAEMIC-EUGLYCAEMIC CLAMP. RESULTS: THERE WERE NO SIGNIFICANT DIFFERENCES BETWEEN THE GROUPS IN THEIR ANTHROPOMETRY OR BODY COMPOSITION. HOWEVER, THE FASTING PLASMA INSULIN WAS SIGNIFICANTLY LOWER IN THE YOGA GROUP. THE YOGA GROUP WAS ALSO MORE INSULIN SENSITIVE (YOGA 7.82 [2.29] V. CONTROL 4.86 [11.97] (MG/[KG.MIN])/(MICROU/ML), P < 0.001). WHILE THE BODY WEIGHT AND WAIST CIRCUMFERENCE WERE NEGATIVELY CORRELATED WITH GLUCOSE DISPOSAL RATE IN THE CONTROLS, THERE WERE NO SIMILAR CORRELATIONS IN THE YOGA GROUP. THE YOGA GROUP HAD SIGNIFICANTLY HIGHER LOW-FREQUENCY POWER AND LOWER NORMALIZED HIGH-FREQUENCY POWER. CONCLUSION: LONG TERM YOGA PRACTICE (FOR 1 YEAR OR MORE) IS ASSOCIATED WITH INCREASED INSULIN SENSITIVITY AND ATTENUATES THE NEGATIVE RELATIONSHIP BETWEEN BODY WEIGHT OR WAIST CIRCUMFERENCE AND INSULIN SENSITIVITY.	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
17  341  31 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	

18 1424  24 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.

19 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
20 1760  33 POSITIVE EFFECTS OF YOGA ON PHYSICAL AND RESPIRATORY FUNCTIONS IN HEALTHY INACTIVE MIDDLE-AGED PEOPLE. CONTEXT: YOGA IMPROVES PHYSICAL AND RESPIRATORY FUNCTIONS IN HEALTHY INACTIVE MIDDLE-AGED PEOPLE. AIM: THIS STUDY AIMED TO ASSESS THE EFFECTS OF 8 WEEKS OF ASANA AND ASANA WITH PRANAYAMA LESSONS IN ORDER TO CLARIFY THE INFLUENCE OF TWO DIFFERENT COMBINATIONS OF YOGA PRACTICE ON PHYSICAL AND RESPIRATORY FUNCTIONS IN HEALTHY INACTIVE MIDDLE-AGED PEOPLE. SUBJECTS AND METHODS: A TOTAL OF 28 PARTICIPANTS (MEAN AGE: 52.7 YEARS) WERE DIVIDED INTO A YOGA ASANA (YA) GROUP AND YA WITH PRANAYAMA (YAP) GROUP. PARTICIPANTS ATTENDED A 70-MIN SESSION ONCE A WEEK FOR 8 WEEKS. THE YA GROUP PRACTICED BASIC ASANA WITHOUT SPECIFIC BREATHING INSTRUCTIONS, WHILE THE YAP GROUP PRACTICED BASIC ASANA WITH SPECIFIC BREATHING INSTRUCTIONS (PRANAYAMA). RESPIRATORY FUNCTION WAS MEASURED WITH AN AUTOSPIROMETER. PHYSICAL FUNCTION ASSESSMENTS INCLUDED THE 30-S CHAIR STAND TEST AND UPPER AND LOWER EXTREMITY FLEXIBILITY. ALL TESTS WERE ASSESSED AT BASELINE AND AFTER 8 WEEKS OF INTERVENTION. STATISTICAL ANALYSIS: CHANGES IN SCORES WERE ANALYZED WITH THE PAIRED T-TEST FOR EACH GROUP. PRE-POST RESULTS WERE COMPARED FOR ALL THE MEASURED VALUES. P < 0.05 WAS CONSIDERED STATISTICALLY SIGNIFICANT. RESULTS: BOTH GROUPS SHOWED SIGNIFICANT IMPROVEMENTS IN PHYSICAL AND OVERALL RESPIRATORY FUNCTIONS AFTER THE 8-WEEK YOGA INTERVENTION. HOWEVER, THE MAXIMAL INSPIRATORY PRESSURE AND LOWER EXTREMITY FLEXIBILITY IMPROVED ONLY IN THE YAP GROUP. CONCLUSIONS: THE 8-WEEK YOGA INTERVENTION FOR HEALTHY INACTIVE MIDDLE-AGED PEOPLE IMPROVED THE OVERALL RESPIRATORY AND PHYSICAL FUNCTIONS, AND THE INCLUSION OF PRANAYAMA HAD THE ADDED BENEFIT OF IMPROVING INSPIRATORY MUSCLE STRENGTH AND GLOBAL BODY FLEXIBILITY.	2019
