1 1266 85 FLUID INTELLIGENCE AND BRAIN FUNCTIONAL ORGANIZATION IN AGING YOGA AND MEDITATION PRACTITIONERS. NUMEROUS STUDIES HAVE DOCUMENTED THE NORMAL AGE-RELATED DECLINE OF NEURAL STRUCTURE, FUNCTION, AND COGNITIVE PERFORMANCE. PRELIMINARY EVIDENCE SUGGESTS THAT MEDITATION MAY REDUCE DECLINE IN SPECIFIC COGNITIVE DOMAINS AND IN BRAIN STRUCTURE. HERE WE EXTENDED THIS RESEARCH BY INVESTIGATING THE RELATION BETWEEN AGE AND FLUID INTELLIGENCE AND RESTING STATE BRAIN FUNCTIONAL NETWORK ARCHITECTURE USING GRAPH THEORY, IN MIDDLE-AGED YOGA AND MEDITATION PRACTITIONERS, AND MATCHED CONTROLS. FLUID INTELLIGENCE DECLINED SLOWER IN YOGA PRACTITIONERS AND MEDITATORS COMBINED THAN IN CONTROLS. RESTING STATE FUNCTIONAL NETWORKS OF YOGA PRACTITIONERS AND MEDITATORS COMBINED WERE MORE INTEGRATED AND MORE RESILIENT TO DAMAGE THAN THOSE OF CONTROLS. FURTHERMORE, MINDFULNESS WAS POSITIVELY CORRELATED WITH FLUID INTELLIGENCE, RESILIENCE, AND GLOBAL NETWORK EFFICIENCY. THESE FINDINGS REVEAL THE POSSIBILITY TO INCREASE RESILIENCE AND TO SLOW THE DECLINE OF FLUID INTELLIGENCE AND BRAIN FUNCTIONAL ARCHITECTURE AND SUGGEST THAT MINDFULNESS PLAYS A MECHANISTIC ROLE IN THIS PRESERVATION.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
2 1289 37 GREATER WIDESPREAD FUNCTIONAL CONNECTIVITY OF THE CAUDATE IN OLDER ADULTS WHO PRACTICE KRIPALU YOGA AND VIPASSANA MEDITATION THAN IN CONTROLS. THERE HAS BEEN A GROWING INTEREST IN UNDERSTANDING HOW CONTEMPLATIVE PRACTICES AFFECT BRAIN FUNCTIONAL ORGANIZATION. HOWEVER, MOST STUDIES HAVE RESTRICTED THEIR EXPLORATION TO PREDEFINED NETWORKS. FURTHERMORE, SCIENTIFIC COMPARISONS OF DIFFERENT CONTEMPLATIVE TRADITIONS ARE LARGELY LACKING. HERE WE EXPLORED DIFFERENCES IN WHOLE BRAIN RESTING STATE FUNCTIONAL CONNECTIVITY BETWEEN EXPERIENCED YOGA PRACTITIONERS, EXPERIENCED MEDITATORS, AND MATCHED CONTROLS. ANALYSES WERE REPEATED IN AN INDEPENDENT SAMPLE OF EXPERIENCED MEDITATORS AND MATCHED CONTROLS. ANALYSES UTILIZING NETWORK-BASED STATISTICS (ZALESKY ET AL., 2010) REVEALED DIFFERENCE COMPONENTS FOR YOGA PRACTITIONERS > CONTROLS AND MEDITATORS > CONTROLS IN WHICH THE RIGHT CAUDATE WAS A CENTRAL NODE. FOLLOW UP ANALYSES REVEALED THAT YOGA PRACTITIONERS AND MEDITATORS HAD SIGNIFICANTLY GREATER DEGREE CENTRALITY IN THE CAUDATE THAN CONTROLS. THIS GREATER DEGREE CENTRALITY WAS NOT DRIVEN BY SINGLE CONNECTIONS BUT BY GREATER CONNECTIVITY BETWEEN THE CAUDATE AND NUMEROUS BRAIN REGIONS. FINDINGS OF GREATER CAUDATE CONNECTIVITY IN MEDITATORS THAN IN CONTROLS WAS REPLICATED IN AN INDEPENDENT DATASET. THESE FINDINGS SUGGEST THAT YOGA AND MEDITATION PRACTITIONERS HAVE STRONGER FUNCTIONAL CONNECTIVITY WITHIN BASAL GANGLIA CORTICO-THALAMIC FEEDBACK LOOPS THAN NON-PRACTITIONERS. ALTHOUGH WE COULD NOT PROVIDE EVIDENCE FOR ITS MECHANISTIC ROLE, THIS GREATER CONNECTIVITY MIGHT BE RELATED TO THE OFTEN REPORTED EFFECTS OF MEDITATION AND YOGA ON BEHAVIORAL FLEXIBILITY, MENTAL HEALTH, AND WELL-BEING.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
3 1641 21 MONITORING THE NEURAL ACTIVITY OF THE STATE OF MENTAL SILENCE WHILE PRACTICING SAHAJA YOGA MEDITATION. OBJECTIVE: TO IDENTIFY THE NEURAL CORRELATES OF THE STATE OF MENTAL SILENCE AS EXPERIENCED THROUGH SAHAJA YOGA MEDITATION. DESIGN: NINETEEN EXPERIENCED MEDITATORS UNDERWENT FUNCTIONAL MAGNETIC RESONANCE IMAGING DURING THREE SHORT CONSECUTIVE MEDITATION PERIODS, CONTRASTED WITH A CONTROL RELAXATION CONDITION. RESULTS: RELATIVE TO BASELINE, AT THE BEGINNING OF THE MEDITATION SESSIONS THERE WAS A SIGNIFICANT INCREASE OF ACTIVATION IN BILATERAL INFERIOR FRONTAL AND TEMPORAL REGIONS. ACTIVATION BECAME PROGRESSIVELY MORE REDUCED WITH DEEPER MEDITATION STAGES AND IN THE LAST MEDITATION SESSION IT BECAME LOCALIZED TO THE RIGHT INFERIOR FRONTAL CORTEX/ RIGHT INSULA AND RIGHT MIDDLE/SUPERIOR TEMPORAL CORTEX. FURTHERMORE, RIGHT INFERIOR FRONTAL ACTIVATION WAS DIRECTLY ASSOCIATED WITH THE SUBJECTIVE DEPTH OF THE MENTAL SILENCE EXPERIENCE. CONCLUSIONS: MEDITATORS APPEAR TO PASS THROUGH AN INITIAL INTENSE NEURAL SELF-CONTROL PROCESS NECESSARY TO SILENCE THEIR MIND. AFTER THIS THEY EXPERIENCE RELATIVELY REDUCED BRAIN ACTIVATION CONCOMITANT WITH THE DEEPENING OF THE STATE OF MENTAL SILENCE OVER RIGHT INFERIOR FRONTAL CORTEX, PROBABLY REFLECTING AN EFFORTLESS PROCESS OF ATTENTIONAL CONTEMPLATION ASSOCIATED WITH THIS STATE.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
4 1972 29 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
5 1543 16 KUNDALINI YOGA FOR GENERALIZED ANXIETY DISORDER: AN EXPLORATION OF TREATMENT EFFICACY AND POSSIBLE MECHANISMS. THE AIM OF THIS STUDY WAS TO EXAMINE THE EFFICACY OF KUNDALINI YOGA IN REDUCING SYMPTOMS OF GENERALIZED ANXIETY DISORDER (GAD) COMPARED TO A COMMON TREATMENT-AS-USUAL CONDITION USING COGNITIVE TECHNIQUES. A SECONDARY OBJECTIVE WAS TO EXPLORE POTENTIAL TREATMENT MECHANISMS. FEMALES AGED 24 TO 75 YEARS WITH GAD ( N = 49) RECEIVED EITHER AN 8-WEEK KUNDALINI YOGA INTERVENTION ( N = 34) OR AN 8-WEEK TREATMENT-AS-USUAL CONDITION ( N = 15). THE YOGA CONDITION RESULTED IN LOWER LEVELS OF ANXIETY RELATIVE TO THE TREATMENT-AS-USUAL CONDITION. FURTHERMORE, CHANGES IN SOMATIC SYMPTOMS MEDIATED TREATMENT OUTCOME FOR KUNDALINI YOGA. KUNDALINI YOGA MAY SHOW PROMISE AS A TREATMENT FOR GAD, AND THIS TREATMENT MIGHT CONVEY ITS EFFECT ON SYMPTOM SEVERITY BY REDUCING SOMATIC SYMPTOMS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
6 2920 19 [THE RELATIONSHIP BETWEEN YOGA IMMERSION, PSYCHOLOGICAL WELL-BEING AND PSYCHIATRIC SYMPTOMS]. BACKGROUND: IN RECENT YEARS POSITIVE EFFECTS OF YOGA (AS A KIND OF SPIRITUAL EXERCISE) IN REGARDS TO SUBJECTIVE WELL-BEING AND PHYSICAL HEALTH CAN BE FOUND AS WELL DOCUMENTED IN THE LITERATURE. METHOD: BASED ON A CONSTRUCT-PSYCHOLOGICAL APPROACH A NEWLY DEVELOPED SCALE FOR THE ASSESSMENT OF YOGA INVOLVEMENT (IMMERSION) WAS VALIDATED ON A SAMPLE OF 233 NON-CLINICAL SUBJECTS (210 FEMALES) BY MEANS OF SOCIO-DEMOGRAPHIC AND WELL ESTABLISHED PSYCHOMETRIC PARAMETERS OF PSYCHOLOGICAL WELL-BEING AND PSYCHIATRIC SYMPTOMS. FURTHERMORE, THE GROUP OF YOGA PRACTITIONERS WAS COMPARED WITH A CONTROL GROUP CONSISTING OF 93 GYMNASTICS PRACTITIONERS (83 WOMEN) WITH RESPECT TO THESE PARAMETERS. RESULTS: THE AMOUNT OF YOGA IMMERSION (YI) CAN BE RELIABLY ASSESSED BY MEANS OF THE ONE-DIMENSIONAL YI-SCALE (10 ITEMS) AND SHOWS TO BE STRONGLY CORRELATED WITH MINDFULNESS (R = .56; P < .01), INNER CORRESPONDENCE (R = .61; P < .01) AND RELIGIOUS/SPIRITUAL WELL-BEING (R = .68; P < .01). FURTHERMORE HIGHLY YOGA-IMMERSIVE PRACTITIONERS EXHIBITED A SIGNIFICANT HIGHER AMOUNT OF PSYCHOLOGICAL WELL-BEING (P < .01) COMPARED TO MARGINALLY/MODERATELY YOGA-IMMERSIVE AND GYMNASTICS PRACTITIONERS. THE YOGA-GROUP ALSO SHOWED A LOWER AMOUNT OF PSYCHIATRIC SYMPTOMS (E.G. DEPRESSION; P < .01). CONCLUSIONS: THE GLOBALLY POSTULATED POSITIVE RELATIONSHIP BETWEEN YOGA-PRACTICING AND MENTAL HEALTH COULD BE CONFIRMED; THEREBY THE IMPACT OF YI CAN BE ASSUMED AS CENTRAL. FURTHER RANDOMIZED CONTROLLED TRIAL RESEARCH FOCUSING ON THE HEALTH/DISEASE-RELATED ASPECTS OF YI MIGHT BE CONDUCTED ESPECIALLY IN CLINICAL GROUPS.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
7  831 17 EFFECT OF YOGA ON MIGRAINE: A COMPREHENSIVE STUDY USING CLINICAL PROFILE AND CARDIAC AUTONOMIC FUNCTIONS. CONTEXT AND AIMS: MIGRAINE IS AN EPISODIC DISABLING HEADACHE REQUIRING LONG-TERM MANAGEMENT. MIGRAINE MANAGEMENT THROUGH YOGA THERAPY WOULD REDUCE THE MEDICATION COST WITH POSITIVE HEALTH BENEFITS. YOGA HAS SHOWN TO IMPROVE THE QUALITY OF LIFE, REDUCE THE EPISODE OF HEADACHE AND MEDICATION. THE AIM OF THE PRESENT STUDY WAS TO EVALUATE THE EFFICACY OF YOGA AS AN ADJUVANT THERAPY IN MIGRAINE PATIENTS BY ASSESSING CLINICAL OUTCOME AND AUTONOMIC FUNCTIONS TESTS. SUBJECTS AND METHODS: MIGRAINE PATIENTS WERE RANDOMLY GIVEN EITHER CONVENTIONAL CARE (N = 30) OR YOGA WITH CONVENTIONAL CARE (N = 30). YOGA GROUP RECEIVED YOGA PRACTICE SESSION FOR 5 DAYS A WEEK FOR 6 WEEKS ALONG WITH CONVENTIONAL CARE. CLINICAL ASSESSMENT (FREQUENCY, INTENSITY OF HEADACHE AND HEADACHE IMPACT) AND AUTONOMIC FUNCTION TEST WERE DONE AT BASELINE AND AT THE END OF THE INTERVENTION. RESULTS: YOGA WITH CONVENTIONAL CARE AND CONVENTION CARE GROUPS SHOWED SIGNIFICANT IMPROVEMENT IN CLINICAL VARIABLES, BUT IT WAS BETTER WITH YOGA THERAPY. IMPROVEMENT IN THE VAGAL TONE ALONG WITH REDUCED SYMPATHETIC ACTIVITY WAS OBSERVED IN PATIENTS WITH MIGRAINE RECEIVING YOGA AS ADJUVANT THERAPY. CONCLUSIONS: INTERVENTION SHOWED SIGNIFICANT CLINICAL IMPROVEMENT IN BOTH GROUPS. HEADACHE FREQUENCY AND INTENSITY WERE REDUCED MORE IN YOGA WITH CONVENTIONAL CARE THAN THE CONVENTIONAL CARE GROUP ALONE. FURTHERMORE, YOGA THERAPY ENHANCED THE VAGAL TONE AND DECREASED THE SYMPATHETIC DRIVE, HENCE IMPROVING THE CARDIAC AUTONOMIC BALANCE. THUS, YOGA THERAPY CAN BE EFFECTIVELY INCORPORATED AS AN ADJUVANT THERAPY IN MIGRAINE PATIENTS.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
8  681 19 EFFECT OF ADD-ON YOGA ON COGNITIVE FUNCTIONS AMONG SUBSTANCE ABUSERS IN A RESIDENTIAL THERAPEUTIC CENTER: RANDOMIZED COMPARATIVE STUDY. BACKGROUND: CHRONIC VULNERABILITY CHARACTERIZES SUBSTANCE ABUSE DISORDER WITH CONSEQUENT RELAPSE. THE PROCESS OF ABSTINENCE DEPENDS ON COGNITIVE RECOVERY. HENCE, BEHAVIORAL INTERVENTION SHOULD ACCOUNT FOR COGNITIVE DIMENSION OF SUBSTANCE ABUSERS. RECENT STUDIES HIGHLIGHT YOGA-BASED INTERVENTION AS A PROMISING ADD-ON THERAPY FOR TREATING AND PREVENTING ADDICTIVE BEHAVIORS. PURPOSE: THE STUDY AIMED TO EVALUATE THE EFFICACY OF A YOGA-BASED INTERVENTION AS AN ADD-ON IN ENHANCING COGNITIVE FUNCTIONS, COMPARED WITH PHYSICAL EXERCISE TO NEWLY ADMITTED SUBSTANCE ABUSERS SEEKING AN INPATIENT TREATMENT PROGRAM. METHODS: THE STUDY WAS A SINGLE-BLIND, RANDOMIZED, COMPARATIVE DESIGN THAT INCLUDED 96 MALE PARTICIPANTS, BETWEEN 18 AND 40 YEARS IN A RESIDENTIAL REHABILITATION TREATMENT UNIT. PARTAKERS IN THE YOGA OR PHYSICAL EXERCISE GROUP RECEIVED SUPERVISED DAILY TRAINING FOR 12 WEEKS, IN ADDITION TO STANDARD REHABILITATION TREATMENT. RATERS BLIND TO THE STUDY ASSESSED THE PATIENTS ON DIGIT SPAN TASK, CANCELLATION TEST, AND STROOP TESTS AT THE BASELINE AND FOLLOWING 12 WEEKS OF INTERVENTION. RESULTS: A SIGNIFICANT ENHANCEMENT IN DIGIT FORWARD (YOGA - P < 0.0005, D = 0.81; EXERCISE - P < 0.0005, D = 0.73), DIGIT BACKWARD (YOGA - P < 0.0005, D = 0.88; EXERCISE - P < 0.0005, D = 0.58), AND LETTER CANCELLATION TEST SCORES (YOGA - P < 0.0005, D = 1.31; EXERCISE - P < 0.0005, D = 1.4) WERE OBSERVED IN BOTH THE YOGA AND THE EXERCISE GROUPS. STROOP WORD AND COLOR TASK SCORES WERE SEEN SIGNIFICANTLY HIGHER FOLLOWING YOGA (P < 0.005, D = 0.74; P < 0.005, D = 1.13) AND EXERCISE (P < 0.0005, D = 0.62; P < 0.0005, D = 0.61). FURTHERMORE, STROOP COLOR-WORD TEST SHOWED SIGNIFICANT ENHANCEMENT AFTER YOGA (P < 0.0005, D = 1.10) AND EXERCISE (P < 0.0005, D = 0.42), WITH DEGREE OF VARIATION HIGHER IN THE YOGA GROUP. CONCLUSION: OUR RESULTS SUGGEST THAT THE ADD-ON YOGA OR EXERCISE-BASED INTERVENTION SHOW ENHANCEMENT OF COGNITIVE FUNCTIONS. THESE FINDINGS PROVIDE THE UTILITY OF YOGA AND EXERCISE-BASED INTERVENTION IN IMPROVING COGNITIVE FUNCTIONS AMONG SUBSTANCE ABUSERS. FURTHERMORE, RIGOROUS TRIALS ARE NEEDED TO EXPLORE THE POTENTIAL LONG-TERM EFFECTS OF THESE PROCEDURES.	2018	
                                                                                                                                                                                                                                                           
9 1359 27 IMMEDIATE EFFECTS OF OM CHANTING ON HEART RATE VARIABILITY MEASURES COMPARED BETWEEN EXPERIENCED AND INEXPERIENCED YOGA PRACTITIONERS. BACKGROUND: CHANTING "OM" IS A FORM OF MEDITATION THAT HAS NUMEROUS HEALTH BENEFITS. HOWEVER, THE NEUROPHYSIOLOGICAL MECHANISMS UNDERPINNING ITS EFFECT ARE SURPRISINGLY SCARCE. THE PRESENT STUDY AIMED TO INVESTIGATE THE EFFECT OF OM CHANTING ON AUTONOMIC MODULATION, USING HEART RATE VARIABILITY (HRV), ON EXPERIENCED YOGA PRACTITIONERS AND YOGA NAIVE PERSONS. METHODS: THIS PROSPECTIVE STUDY INCLUDED 19 YOGA PRACTITIONERS (9 FEMALES AND 10 MALES; GROUP MEAN AGE +/- STANDARD DEVIATION [SD]; 25.9 +/- 3.2 YEARS) AND 17 YOGA NAIVE PERSONS (8 FEMALES AND 9 MALES; GROUP MEAN AGE +/- SD; 24.8 +/- 3.6 YEARS) OF BOTH SEXES AND SIMILAR AGE RANGE. BOTH THE GROUPS WERE ASSESSED FOR HRV INDICES (TIME AND FREQUENCY DOMAIN MEASURES) BEFORE AND AFTER LOUD OM CHANTING FOR 5 MIN. RESULTS: BASELINE COMPARISON USING MANN-WHITNEY U TEST BETWEEN GROUPS SHOWED YOGA PRACTITIONERS HAD SIGNIFICANTLY INCREASED HIGH FREQUENCY (HF) POWER (P < 0.029) THAN NONYOGA PRACTITIONERS, SIGNIFYING A STATE OF TRANQUILITY BEFORE THE CHANTING OF OM. AFTER 5 MIN OF LOUD CHANTING OF OM, A COMPARISON BETWEEN GROUPS ASSESSED USING WILCOXON SIGNED RANKS TEST REVEALED: HF POWER, A COMPONENT OF THE PARASYMPATHETIC NERVOUS SYSTEM, WAS FURTHER AMPLIFIED WITH A SIGNIFICANTLY INCREASE (P < 0.001) IN THE YOGA PRACTITIONERS GROUP COMPARED TO NONYOGA PRACTITIONERS. FURTHERMORE, THIS INCREASE IN HF POWER WAS POSITIVELY CORRELATED WITH THE YEARS OF EXPERIENCE IN YOGA. CONCLUSION: THE PRESENT STUDY SHOWED THAT A BRIEF CHANTING OF OM (5 MIN) MIGHT ENHANCE PARASYMPATHETIC NERVOUS SYSTEM ACTIVITY, PROMOTE RELAXATION, AND PROVIDE CALMNESS. FURTHER, THIS EXPERIENCE MAY BE ACHIEVED EFFECTIVELY IN INDIVIDUALS EXPERIENCED IN YOGA THAN NONYOGA PRACTITIONERS.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
10 2436 20 YOGA AND PSYCHIATRIC DISORDERS: A REVIEW OF BIOMARKER EVIDENCE. TRADITIONALLY, YOGA HAS BEEN USED AS A MEANS FOR SPIRITUAL GROWTH BUT OVER THE PAST TWO DECADES OR SO ITS THERAPEUTIC BENEFITS IN PSYCHIATRIC DISORDERS HAVE BEEN SCIENTIFICALLY EXPLORED. YOGA HAS BEEN SHOWN TO BE USEFUL AS A MONO-THERAPY IN MILD TO MODERATE DEPRESSION AND AS AN ADJUVANT IN SEVERAL PSYCHIATRIC DISORDERS INCLUDING SCHIZOPHRENIA, ANXIETY DISORDERS, SUBSTANCE USE DISORDERS AND MILD COGNITIVE IMPAIRMENT. FURTHERMORE, SYSTEMATIC ATTEMPTS HAVE BEEN MADE TO UNDERSTAND THE BIOLOGICAL CORRELATES OF YOGA IN THESE PSYCHIATRIC DISORDERS. GIVEN THAT NO PSYCHIATRIC DISORDER HAS STRONG AND ESTABLISHED BIOMARKERS, IT IS INTERESTING THAT PRELIMINARY RESEARCH HAS DEMONSTRATED SIGNIFICANT CHANGES IN CERTAIN IMPORTANT BIOMARKERS FOLLOWING REGULAR YOGA PRACTICE. IN THIS BRIEF REVIEW, WE PROVIDE AN UPDATE ON THE EFFECTS OF YOGA ON BIOCHEMICAL, NEURO-PHYSIOLOGICAL AND NEURO-IMAGING RELATED BIO-MARKERS IN PSYCHIATRIC DISORDERS. ALTHOUGH FINDINGS AND TRENDS ARE PROMISING, MUCH MORE RESEARCH IS WARRANTED TO ESTABLISH A DEFINITE BIOLOGICAL BASIS FOR YOGA IN PSYCHIATRY.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
11  690 24 EFFECT OF COMBINED YOGA AND TRANSCRANIAL DIRECT CURRENT STIMULATION INTERVENTION ON WORKING MEMORY AND MINDFULNESS. TRANSCRANIAL DIRECT STIMULATION, A NON-INVASIVE NEUROSTIMULATION TECHNIQUE FOR MODULATING CORTICAL EXCITABILITY, AND YOGA HAVE BOTH RESPECTIVELY BEEN SHOWN TO POSITIVELY AFFECT COGNITION. WHILE PRELIMINARY RESEARCH HAS SHOWN THAT COMBINED TRANSCRANIAL DIRECT STIMULATION AND MEDITATION MAY HAVE SYNERGISTIC EFFECTS ON MOOD AND COGNITION, THIS WAS THE FIRST STUDY TO EXPLORE THE COMBINATION OF TRANSCRANIAL DIRECT STIMULATION AND YOGA. TWENTY-TWO HEALTHY VOLUNTEERS WITH A REGULAR YOGA PRACTICE WERE RANDOMIZED TO RECEIVE EITHER ACTIVE TRANSCRANIAL DIRECT STIMULATION (ANODAL LEFT, CATHODAL RIGHT DORSOLATERAL PREFRONTAL CORTEX) FOLLOWED BY YOGA INTERVENTION OR SHAM TRANSCRANIAL DIRECT STIMULATION FOLLOWED BY YOGA INTERVENTION A DOUBLE-BLIND, CROSS-OVER DESIGN OVER TWO SEPARATE INTERVENTION DAYS. OUTCOME MEASURES INCLUDED WORKING MEMORY PERFORMANCE, MEASURED WITH THE N-BACK TASK AND MINDFULNESS STATE, MEASURED WITH THE TORONTO MINDFULNESS SCALE, AND WERE CONDUCTED OFFLINE, WITH PRE-POST ASSESSMENTS. TWENTY PARTICIPANTS COMPLETED BOTH DAYS OF THE INTERVENTION. ACTIVE TRANSCRANIAL DIRECT STIMULATION DID NOT HAVE A SIGNIFICANT EFFECT ON WORKING MEMORY OR LEVELS OF MINDFULNESS. THERE WAS A SIGNIFICANT PLACEBO EFFECT, WITH BETTER PERFORMANCE ON DAY 1 OF THE INTERVENTION, IRRESPECTIVE OF WHETHER PARTICIPANTS RECEIVED ACTIVE OR SHAM TRANSCRANIAL DIRECT STIMULATION. THERE WAS NO SIGNIFICANT DIFFERENCE BETWEEN ACTIVE VERSUS SHAM TRANSCRANIAL DIRECT STIMULATION CONCERNING WORKING MEMORY PERFORMANCE AND MINDFULNESS, WHICH MAY BE ACCOUNTED BY THE SMALL SAMPLE SIZE, THE TRANSIENT NATURE OF THE INTERVENTION, THE FACT THAT YOGA AND TRANSCRANIAL DIRECT STIMULATION CONCERNING WERE NOT CONDUCTED SIMULTANEOUSLY, AND THE SPECIFIC SITE OF STIMULATION.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
12 1871 15 RANGE OF YOGA INTENSITIES FROM SAVASANA TO SWEATING: A SYSTEMATIC REVIEW. BACKGROUND: THERE IS LIMITED RESEARCH EXAMINING THE INTENSITY OF YOGA AND INTENSITY VARIATIONS BETWEEN DIFFERENT STYLES. THE PURPOSE OF THIS REVIEW IS TO EXAMINE THE INTENSITY OF YOGA BASED ON DIFFERENT PHYSIOLOGIC RESPONSES BOTH BETWEEN DIFFERENT YOGA STYLES AND WITHIN STYLES OF YOGA. METHODS: ARTICLES WERE SEARCHED FOR ON THE PUBMED DATABASE IN EARLY 2019. INCLUSION CRITERIA WERE AS FOLLOWS: (1) WRITTEN IN ENGLISH, (2) CITE A SPECIFIC STYLE OF YOGA AND INCLUDE WHOLE YOGA SESSION, AND (3) MEASURE METABOLIC OR HEART RATE RESPONSE. RESULTS: TEN ARTICLES WERE REVIEWED; ARTICLES REPORTED OXYGEN CONSUMPTION (N = 1), HEART RATE (N = 4), OR BOTH VARIABLES (N = 5). YOGA STYLES ASSESSED INCLUDED ASHTANGA (N = 2), BIKRAM (N = 3), GENTLE (N = 1), HATHA (N = 3), IYENGAR (N = 1), POWER (N = 1), AND VINYASA (N = 1). OXYGEN CONSUMPTION COMMONLY CATEGORIZED YOGA AS A LIGHT-INTENSITY ACTIVITY, WHILE HEART RATE RESPONSES CLASSIFIED DIFFERENT YOGA INTO MULTIPLE INTENSITIES. CONCLUSION: THIS REVIEW DEMONSTRATES THAT LARGE DIFFERENCES IN INTENSITY CLASSIFICATIONS ARE OBSERVED BETWEEN DIFFERENT STYLES OF YOGA. FURTHERMORE, METABOLIC AND HEART RATE RESPONSES CAN BE VARIABLE, LEADING TO INCONSISTENT INTENSITY CLASSIFICATIONS. THIS IS LIKELY DUE TO THEIR NONLINEAR RELATIONSHIP DURING YOGA. THUS, IT IS IMPERATIVE THAT THE FIELD OF YOGA RESEARCH WORKS TOGETHER TO CREATE A STANDARD FOR REPORTING YOGA.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
13 1424 18 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
14 2369 33 WHAT ARE THE KNOWN EFFECTS OF YOGA ON THE BRAIN IN RELATION TO MOTOR PERFORMANCES, BODY AWARENESS AND PAIN? A NARRATIVE REVIEW. OBJECTIVE: THE CURRENT BODY OF LITERATURE WAS REVIEWED TO EVALUATE THE EFFECTS OF YOGA ON THE BRAIN IN RELATION TO MOTOR PERFORMANCE, BODY AWARENESS AND PAIN. BACKGROUND: YOGA HAS BEEN INCREASINGLY POPULAR IN THE WESTERN COUNTRIES ESPECIALLY FOR ITS UNIQUE INTEGRATION OF THE MIND AND BODY. YOGA HAS BEEN STUDIED MORE INTENSELY IN THE LAST DECADE. ALTHOUGH IT HAS BEEN SHOWN TO IMPROVE COGNITIVE FUNCTIONS, FEW STUDIES HAVE LOOKED INTO THE EFFECTS OF YOGA ON IMPROVING MOTOR PERFORMANCE, BODY AWARENESS OR PAIN AND THE POSSIBLE UNDERLYING BRAIN MECHANISMS ASSOCIATED WITH THEM. METHODS: A SEARCH OF THE CURRENT LITERATURE WAS MADE USING KEYWORDS SUCH AS: "YOGA BRAIN MOTOR", "YOGA BRAIN PAIN", "EFFECTS YOGA BRAIN" AND "EFFECTS YOGA BRAIN MOTOR PERFORMANCE". THE FINDINGS WERE THEN DISCUSSED IN RELATION TO MOTOR PERFORMANCE, BODY AWARENESS AND PAIN AND THEIR REPORTED MECHANISMS OF ACTION ON THE BRAIN. RESULTS: A TOTAL OF 61 ARTICLES WERE SELECTED, OUT OF WHICH 29 WERE EXCLUDED BECAUSE THEY DID NOT MEET OUR CRITERIA. A TOTAL OF THIRTY-TWO ARTICLES WERE INCLUDED IN THIS REVIEW, WHICH WE FURTHER SUBDIVIDED BY FOCUS: MOTOR PERFORMANCE (N=10), BODY AWARENESS (N=14) AND PAIN (N=8). DISCUSSION: OUR REVIEW SHOWS THAT YOGA HAS A POSITIVE EFFECT ON LEARNING RATE, SPEED AND ACCURACY OF A MOTOR TASK BY INCREASING ATTENTION AND DECREASING STRESS THROUGH A BETTER CONTROL OF SENSORIMOTOR RHYTHMS. YOGA ALSO SEEMS TO IMPROVE SENSORY AWARENESS AND INTEROCEPTION, REGULATE AUTONOMIC INPUT, INCREASE PARASYMPATHETIC ACTIVITY AND PROMOTE SELF-REGULATION. YOGA WAS ALSO SHOWN TO REDUCE THE THREAT SIGNAL, INCREASE PAIN TOLERANCE, DECREASE PAIN UNPLEASANTNESS AND DECREASE THE ANXIETY AND DISTRESS ASSOCIATED WITH PAIN. THOSE CHANGES ARE ASSOCIATED WITH THE RECRUITMENT OF SPECIFIC BRAIN AREAS SUCH AS THE INSULA, THE AMYGDALA AND THE HIPPOCAMPUS. CONCLUSION: BASED ON THE STUDIES REVIEWED IN THIS REPORT, WE FOUND THAT THE PRACTICE OF YOGA SEEMS TO FACILITATE MOTOR LEARNING, TO INCREASE BODY AWARENESS AND TO DECREASE PAIN. THESE ARE ASSOCIATED WITH A WIDE VARIETY OF CHANGES IN TERMS OF BRAIN ACTIVITY AND STRUCTURE. FURTHER STUDIES ARE NECESSARY TO REVEAL ITS PRECISE MECHANISM OF ACTION ON THE BRAIN AND TO VALIDATE ITS WIDER APPLICATION IN CLINICAL SETTINGS.	2019	
                                                                                                                                                                                    
15  427 17 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	

16 1098 23 EFFECTS OF YOGA RESPIRATORY PRACTICE (BHASTRIKA PRANAYAMA) ON ANXIETY, AFFECT, AND BRAIN FUNCTIONAL CONNECTIVITY AND ACTIVITY: A RANDOMIZED CONTROLLED TRIAL. PRANAYAMA REFERS TO A SET OF YOGA BREATHING EXERCISES. RECENT EVIDENCE SUGGESTS THAT THE PRACTICE OF PRANAYAMA HAS POSITIVE EFFECTS ON MEASURES OF CLINICAL STRESS AND ANXIETY. THIS STUDY EXPLORED THE IMPACT OF A BHASTRIKA PRANAYAMA TRAINING PROGRAM ON EMOTION PROCESSING, ANXIETY, AND AFFECT. WE USED A RANDOMIZED CONTROLLED TRIAL DESIGN WITH THIRTY HEALTHY YOUNG ADULTS ASSESSED AT BASELINE AND AFTER 4 WEEKS OF PRANAYAMA PRACTICES. TWO FUNCTIONAL MAGNETIC RESONANCE IMAGING (MRI) PROTOCOLS WERE USED BOTH AT BASELINE AND POST-INTERVENTION: AN EMOTION TASK AS WELL AS A RESTING-STATE ACQUISITION. OUR RESULTS SUGGEST THAT PRANAYAMA SIGNIFICANTLY DECREASED STATES OF ANXIETY AND NEGATIVE AFFECT. THE PRACTICE OF PRANAYAMA ALSO MODULATED THE ACTIVITY OF BRAIN REGIONS INVOLVED IN EMOTIONAL PROCESSING, PARTICULARLY THE AMYGDALA, ANTERIOR CINGULATE, ANTERIOR INSULA, AND PREFRONTAL CORTEX. RESTING-STATE FUNCTIONAL MRI (FMRI) SHOWED SIGNIFICANTLY REDUCED FUNCTIONAL CONNECTIVITY INVOLVING THE ANTERIOR INSULA AND LATERAL PORTIONS OF THE PREFRONTAL CORTEX. CORRELATION ANALYSIS REVEALED THAT CHANGES IN CONNECTIVITY BETWEEN THE VENTROLATERAL PREFRONTAL CORTEX AND THE RIGHT ANTERIOR INSULA WERE ASSOCIATED WITH CHANGES IN ANXIETY. ALTHOUGH IT SHOULD BE NOTED THAT THESE ANALYSES WERE PRELIMINARY AND EXPLORATORY, IT PROVIDES THE FIRST EVIDENCE THAT 4 WEEKS OF B. PRANAYAMA SIGNIFICANTLY REDUCE THE LEVELS OF ANXIETY AND NEGATIVE AFFECT, AND THAT THESE CHANGES ARE ASSOCIATED WITH THE MODULATION OF ACTIVITY AND CONNECTIVITY IN BRAIN AREAS INVOLVED IN EMOTION PROCESSING, ATTENTION, AND AWARENESS. THE STUDY WAS REGISTERED AT HTTPS://WWW.ENSAIOSCLINICOS.GOV.BR/RG/RBR-2GV5C2/(RBR-2GV5C2).	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
17 1646 17 MOTIVATIONS FOR ADOPTING AND MAINTAINING A YOGA PRACTICE: A NATIONAL CROSS-SECTIONAL SURVEY. BACKGROUND: YOGA PRACTICE IS BECOMING INCREASINGLY POPULAR AROUND THE WORLD, YET LITTLE IS KNOWN REGARDING WHY PEOPLE ADOPT THE PRACTICE OF YOGA OR HOW THEIR REASONS FOR PRACTICE CHANGE WITH CONTINUED PRACTICE. FURTHERMORE, WHETHER THOSE WHO PRACTICE DIFFERENT TYPES OF YOGA HAVE DIFFERENT MOTIVES REMAINS UNKNOWN. METHODS: TO ADDRESS THESE ISSUES, THE AUTHORS CONDUCTED A NATIONAL CROSS-SECTIONAL ONLINE SURVEY OF 1,702 YOGA PRACTITIONERS IN GERMANY, ASKING ABOUT DEMOGRAPHIC INFORMATION AND MOTIVES FOR INITIATING AND CONTINUING YOGA PRACTICE. RESULTS: THE MOST COMMON PRIMARY REASONS FOR STARTING YOGA WERE RELAXATION (26.6%) AND PREVENTION (25.5%), WHICH WERE ALSO THE MOST COMMON SECONDARY REASONS. NINE HUNDRED AND FORTY-ONE (55.3%) REPORTED A DIFFERENT PRIMARY REASON FOR MAINTAINING THAN FOR ADOPTING YOGA PRACTICE. PREVENTION (38.4%) AND SPIRITUALITY (26.4%) WERE THE MOST COMMONLY REPORTED PRIMARY REASONS FOR MAINTAINING YOGA PRACTICE. MORE HIGHLY EDUCATED PARTICIPANTS AND THOSE PRACTICING LONGER THAN 5 YEARS AT THE TIME OF THE SURVEY WERE MORE LIKELY TO HAVE REPORTED A DIFFERENT CURRENT PRIMARY REASON FOR YOGA PRACTICE THAN THAT FOR WHICH THEY STARTED PRACTICING. CONCLUSIONS: THESE RESULTS SHED LIGHT ON YOGA'S APPEAL TO NOVICES AND REGULAR PRACTITIONERS, WITH IMPORTANT IMPLICATIONS FOR MAKING YOGA APPEALING TO BEGINNERS AS WELL AS PROMOTING THE PRACTICE AS A LONG-TERM LIFESTYLE BEHAVIOR.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
18  225 24 A SYSTEMATIC REVIEW OF MECHANISMS OF CHANGE IN BODY-ORIENTED YOGA IN MAJOR DEPRESSIVE DISORDERS. INTRODUCTION: DESPITE EMPIRICAL EVIDENCE FOR THE EFFICACY OF BODY-ORIENTED YOGA AS ADD-ON TREATMENT FOR MAJOR DEPRESSIVE DISORDER (MDD), THE SPECIFIC MECHANISMS BY WHICH YOGA LEADS TO THERAPEUTIC CHANGES REMAIN UNCLEAR. BY MEANS OF A SYSTEMATIC REVIEW, WE EVALUATE HOW THE FIELD IS PROGRESSING IN ITS EMPIRICAL INVESTIGATION OF MECHANISMS OF CHANGE IN YOGA FOR MDD. METHODS: TO IDENTIFY RELEVANT STUDIES, A SYSTEMATIC SEARCH WAS CONDUCTED. RESULTS: THE SEARCH PRODUCED 441 ARTICLES, OF WHICH 5 WERE INCLUDED, THAT EMPIRICALLY EXAMINED 2 PSYCHOLOGICAL MECHANISMS (MINDFULNESS, RUMINATION) AND 3 BIOLOGICAL MECHANISMS (VAGAL CONTROL, HEART RATE VARIABILITY [HRV], BRAIN-DERIVED NEUROTROPHIC FACTOR [BDNF], CORTISOL). 2 STUDIES FOUND THAT DECREASED RUMINATION AND 1 STUDY THAT INCREASED MINDFULNESS WAS ASSOCIATED WITH THE EFFECT OF YOGA ON TREATMENT OUTCOME. IN ADDITION, PRELIMINARY STUDIES SUGGEST THAT ALTERATIONS IN CORTISOL, BDNF, AND HRV MAY PLAY A ROLE IN HOW YOGA EXERTS ITS CLINICAL EFFECT. DISCUSSION: THE RESULTS SUGGEST THAT BODY-ORIENTED YOGA COULD WORK THROUGH SOME OF THE THEORETICALLY PREDICTED MECHANISMS. HOWEVER, THERE IS A NEED FOR MORE RIGOROUS DESIGNS THAT CAN ASSESS GREATER LEVELS OF CAUSAL SPECIFICITY.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
19 1334 21 HOW DOES EXERCISE IMPROVE IMPLICIT EMOTION REGULATION ABILITY: PRELIMINARY EVIDENCE OF MIND-BODY EXERCISE INTERVENTION COMBINED WITH AEROBIC JOGGING AND MINDFULNESS-BASED YOGA. PURPOSE: THE PRIMARY AIM OF THE PRESENT STUDY IS TO EXAMINE THE EFFECT OF 8-WEEK MIND-BODY EXERCISE INTERVENTION COMBINING AEROBIC JOGGING AND MINDFULNESS-BASED YOGA ON IMPLICIT EMOTION REGULATION ABILITY. THE SECONDARY AIM IS TO EXPLORE THE SPECIFIC POTENTIAL PATHWAYS BY WHICH THE MIND-BODY EXERCISE INTERVENTION FOSTERS IMPLICIT EMOTION REGULATION. THIS MAY HELP US TO UNDERSTAND HOW THE KEY COMPONENTS OF EXERCISE INTERVENTION CONTRIBUTE TO EMOTIONAL BENEFITS. METHODS: SIXTY PARTICIPANTS WERE RANDOMLY ALLOCATED TO ONE OF TWO PARALLEL GROUPS: (1) THE INTERVENTION GROUP (N = 29) AND (2) THE WAITLIST CONTROL GROUP (N = 31). PARTICIPANTS WERE ASKED TO FILL OUT SCALES MEASURING MINDFULNESS AND INSTRUCTED TO COMPLETE AN EMOTION REGULATION TASK TO ASSESS IMPLICIT EMOTION REGULATION ABILITY AS WELL AS THE PWC 170 TEST TO EVALUATE AEROBIC FITNESS BEFORE AND AFTER THE INTERVENTION. RESULTS: THE RESULTS OF THE TWO-WAY REPEATED ANOVA REVEALED THAT 8 WEEKS OF INTERVENTION IMPROVED IMPLICIT EMOTION REGULATION, MINDFULNESS, AND AEROBIC FITNESS LEVELS. PATH ANALYSIS SHOWED THAT ONLY IMPROVED AEROBIC FITNESS MEDIATED THE INTERVENTION EFFECT ON IMPLICIT EMOTION REGULATION ABILITY, CONTROLLING FOR CHANGE IN NEGATIVE AFFECT. NOTABLY, THE RELATIONSHIP BETWEEN THE EFFECTS ON IMPLICIT EMOTION REGULATION ABILITY AND AEROBIC FITNESS WAS MODERATED BY IMPROVED MINDFULNESS. CONCLUSION: EIGHT WEEKS OF MIND-BODY EXERCISE INTERVENTION IMPROVES IMPLICIT EMOTION REGULATION ABILITY. THE AEROBIC FITNESS MAY BE AN ESSENTIAL PATHWAY WHICH MEDIATES THE EFFICACY ON IMPLICIT EMOTION REGULATION ABILITY. FURTHERMORE, DIFFERENT COMPONENTS, SUCH AS AEROBIC FITNESS AND MINDFULNESS, MAY INTERACTIVELY CONTRIBUTE TO SUCH EMOTIONAL BENEFITS.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
20  455 28 CHANGES IN NEURAL CONNECTIVITY AND MEMORY FOLLOWING A YOGA INTERVENTION FOR OLDER ADULTS: A PILOT STUDY. BACKGROUND: NO STUDY HAS EXPLORED THE EFFECT OF YOGA ON COGNITIVE DECLINE AND RESTING-STATE FUNCTIONAL CONNECTIVITY. OBJECTIVES: THIS STUDY EXPLORED THE RELATIONSHIP BETWEEN PERFORMANCE ON MEMORY TESTS AND RESTING-STATE FUNCTIONAL CONNECTIVITY BEFORE AND AFTER A YOGA INTERVENTION VERSUS ACTIVE CONTROL FOR SUBJECTS WITH MILD COGNITIVE IMPAIRMENT (MCI). METHODS: PARTICIPANTS ( >/= 55 Y) WITH MCI WERE RANDOMIZED TO RECEIVE A YOGA INTERVENTION OR ACTIVE "GOLD-STANDARD" CONTROL (I.E., MEMORY ENHANCEMENT TRAINING (MET)) FOR 12 WEEKS. RESTING-STATE FUNCTIONAL MAGNETIC RESONANCE IMAGING WAS USED TO MAP CORRELATIONS BETWEEN BRAIN NETWORKS AND MEMORY PERFORMANCE CHANGES OVER TIME. DEFAULT MODE NETWORKS (DMN), LANGUAGE AND SUPERIOR PARIETAL NETWORKS WERE CHOSEN AS NETWORKS OF INTEREST TO ANALYZE THE ASSOCIATION WITH CHANGES IN VERBAL AND VISUOSPATIAL MEMORY PERFORMANCE. RESULTS: FOURTEEN YOGA AND 11 MET PARTICIPANTS COMPLETED THE STUDY. THE YOGA GROUP DEMONSTRATED A STATISTICALLY SIGNIFICANT IMPROVEMENT IN DEPRESSION AND VISUOSPATIAL MEMORY. WE OBSERVED IMPROVED VERBAL MEMORY PERFORMANCE CORRELATED WITH INCREASED CONNECTIVITY BETWEEN THE DMN AND FRONTAL MEDIAL CORTEX, PREGENUAL ANTERIOR CINGULATE CORTEX, RIGHT MIDDLE FRONTAL CORTEX, POSTERIOR CINGULATE CORTEX, AND LEFT LATERAL OCCIPITAL CORTEX. IMPROVED VERBAL MEMORY PERFORMANCE POSITIVELY CORRELATED WITH INCREASED CONNECTIVITY BETWEEN THE LANGUAGE PROCESSING NETWORK AND THE LEFT INFERIOR FRONTAL GYRUS. IMPROVED VISUOSPATIAL MEMORY PERFORMANCE CORRELATED INVERSELY WITH CONNECTIVITY BETWEEN THE SUPERIOR PARIETAL NETWORK AND THE MEDIAL PARIETAL CORTEX. CONCLUSION: YOGA MAY BE AS EFFECTIVE AS MET IN IMPROVING FUNCTIONAL CONNECTIVITY IN RELATION TO VERBAL MEMORY PERFORMANCE. THESE FINDINGS SHOULD BE CONFIRMED IN LARGER PROSPECTIVE STUDIES.	2016
