1  451 165 CHANGES IN FATIGUE, AUTONOMIC FUNCTIONS, AND BLOOD BIOMARKERS DUE TO SITTING ISOMETRIC YOGA IN PATIENTS WITH CHRONIC FATIGUE SYNDROME. BACKGROUND: IN A PREVIOUS RANDOMIZED CONTROLLED TRIAL, WE FOUND THAT SITTING ISOMETRIC YOGA IMPROVES FATIGUE IN PATIENTS WITH CHRONIC FATIGUE SYNDROME (CFS) WHO ARE RESISTANT TO CONVENTIONAL THERAPY. THE AIM OF THIS STUDY WAS TO INVESTIGATE POSSIBLE MECHANISMS BEHIND THIS FINDING, FOCUSING ON THE SHORT-TERM FATIGUE-RELIEVING EFFECT, BY COMPARING AUTONOMIC NERVOUS FUNCTION AND BLOOD BIOMARKERS BEFORE AND AFTER A SESSION OF ISOMETRIC YOGA. METHODS: FIFTEEN PATIENTS WITH CFS WHO REMAINED SYMPTOMATIC DESPITE AT LEAST 6 MONTHS OF CONVENTIONAL THERAPY PRACTICED SITTING ISOMETRIC YOGA (BIWEEKLY 20 MIN PRACTICE WITH A YOGA INSTRUCTOR AND DAILY HOME PRACTICE) FOR EIGHT WEEKS. ACUTE EFFECTS OF SITTING ISOMETRIC YOGA ON FATIGUE, AUTONOMIC FUNCTION, AND BLOOD BIOMARKERS WERE INVESTIGATED AFTER THE FINAL SESSION WITH AN INSTRUCTOR. THE EFFECT OF A SINGLE SESSION OF SITTING ISOMETRIC YOGA ON FATIGUE WAS ASSESSED BY THE PROFILE OF MOOD STATUS (POMS) QUESTIONNAIRE IMMEDIATELY BEFORE AND AFTER THE SESSION. AUTONOMIC NERVOUS FUNCTION (HEART RATE (HR) VARIABILITY) AND BLOOD BIOMARKERS (CORTISOL, DHEA-S, TNF-ALPHA, IL-6, IFN-GAMMA, IFN-ALPHA, PROLACTIN, CARNITINE, TGF-BETA1, BDNF, MHPG, AND HVA) WERE COMPARED BEFORE AND AFTER THE SESSION. RESULTS: SITTING ISOMETRIC YOGA SIGNIFICANTLY REDUCED THE POMS FATIGUE SCORE (P < 0.01) AND INCREASED THE VIGOR SCORE (P < 0.01). IT ALSO REDUCED HR (P < 0.05) AND INCREASED THE HIGH FREQUENCY POWER (P < 0.05) OF HR VARIABILITY. SITTING ISOMETRIC YOGA INCREASED SERUM LEVELS OF DHEA-S (P < 0.05), REDUCED LEVELS OF CORTISOL (P < 0.05) AND TNF-ALPHA (P < 0.05), AND HAD A TENDENCY TO REDUCE SERUM LEVELS OF PROLACTIN (P < 0.1). DECREASES IN FATIGUE SCORES CORRELATED WITH CHANGES IN PLASMA LEVELS OF TGF-BETA1 AND BDNF. IN CONTRAST, INCREASED VIGOR POSITIVELY CORRELATED WITH HVA. CONCLUSIONS: A SINGLE SESSION OF SITTING ISOMETRIC YOGA REDUCED FATIGUE AND INCREASED VIGOR IN PATIENTS WITH CFS. YOGA ALSO INCREASED VAGAL NERVE FUNCTION AND CHANGED BLOOD BIOMARKERS IN A PATTERN THAT SUGGESTED ANTI-STRESS AND ANTI-INFLAMMATORY EFFECTS. THESE CHANGES APPEAR TO BE RELATED TO THE SHORT-TERM FATIGUE-RELIEVING EFFECT OF SITTING ISOMETRIC YOGA IN PATIENTS WITH CFS. FURTHERMORE, DOPAMINERGIC NERVOUS SYSTEM ACTIVATION MIGHT ACCOUNT FOR SITTING ISOMETRIC YOGA-INDUCED INCREASES IN ENERGY IN THIS PATIENT POPULATION.

2 2250 111 THE LONGITUDINAL EFFECTS OF SEATED ISOMETRIC YOGA ON BLOOD BIOMARKERS, AUTONOMIC FUNCTIONS, AND PSYCHOLOGICAL PARAMETERS OF PATIENTS WITH CHRONIC FATIGUE SYNDROME: A PILOT STUDY. BACKGROUND: IN A PREVIOUS RANDOMIZED CONTROLLED TRIAL, WE FOUND THAT PRACTICING SEATED ISOMETRIC YOGA REGULARLY FOR 2 MONTHS IMPROVED THE FATIGUE OF PATIENTS WITH CHRONIC FATIGUE SYNDROME (CFS) WHO ARE RESISTANT TO CONVENTIONAL THERAPY. THE AIM OF THIS PILOT STUDY WAS TO INVESTIGATE THE POSSIBLE MECHANISMS BEHIND THIS FINDING BY COMPARING BLOOD BIOMARKERS, AUTONOMIC NERVOUS FUNCTION, AND PSYCHOLOGICAL INDICES BEFORE VERSUS AFTER AN INTERVENTION PERIOD OF SEATED ISOMETRIC YOGA PRACTICE. METHODS: FIFTEEN PATIENTS WITH CFS WHO DID NOT SHOW SATISFACTORY IMPROVEMENTS AFTER AT LEAST 6 MONTHS OF CONVENTIONAL THERAPY PRACTICED SEATED ISOMETRIC YOGA (BIWEEKLY 20-MIN SESSIONS WITH A YOGA INSTRUCTOR AND DAILY PRACTICE AT HOME) FOR 2 MONTHS. THE LONGITUDINAL EFFECTS OF SEATED ISOMETRIC YOGA ON FATIGUE, BLOOD BIOMARKERS, AUTONOMIC FUNCTION, AND PSYCHOLOGICAL STATE WERE INVESTIGATED BY COMPARING THE FOLLOWING PARAMETERS BEFORE AND AFTER THE INTERVENTION PERIOD: FATIGUE SEVERITY WAS ASSESSED BY THE CHALDER FATIGUE SCALE (FS) SCORE. LEVELS OF THE BLOOD BIOMARKERS CORTISOL, DHEA-S, TNF-ALPHA, IL-6, PROLACTIN, CARNITINE, TGF-BETA1, BDNF, MHPG, HVA, AND ALPHA-MSH WERE MEASURED. THE AUTONOMIC NERVOUS FUNCTIONS ASSESSED WERE HEART RATE (HR) AND HR VARIABILITY. PSYCHOLOGICAL INDICES INCLUDED THE 20-ITEM TORONTO ALEXITHYMIA SCALE (TAS-20) AND THE HOSPITAL ANXIETY AND DEPRESSION SCALE (HADS). RESULTS: PRACTICING SEATED ISOMETRIC YOGA FOR 2 MONTHS RESULTED IN SIGNIFICANT REDUCTIONS IN THE CHALDER FS (P = 0.002) AND HADS-DEPRESSION (P = 0.02) SCORES. NO SIGNIFICANT CHANGES WERE OBSERVED IN ANY OTHER PARAMETER EVALUATED. THE CHANGE IN CHALDER FS SCORE WAS NOT CORRELATED WITH THE CHANGE IN HADS-DEPRESSION SCORE. HOWEVER, THIS CHANGE WAS POSITIVELY CORRELATED WITH CHANGES IN THE SERUM TNF-ALPHA LEVELS (P = 0.048), THE HIGH FREQUENCY COMPONENT OF HR VARIABILITY (P = 0.042), AND TAS-20 SCORES (P = 0.001). CONCLUSIONS: REGULAR PRACTICE OF SEATED ISOMETRIC YOGA FOR 2 MONTHS REDUCED THE FATIGUE AND DEPRESSIVE SYMPTOM SCORES OF PATIENTS WITH CFS WITHOUT AFFECTING ANY OTHER PARAMETERS WE INVESTIGATED. THIS STUDY FAILED TO IDENTIFY THE MARKERS RESPONSIBLE FOR THE LONGITUDINAL FATIGUE-RELIEVING EFFECT OF SEATED ISOMETRIC YOGA. HOWEVER, CONSIDERING THAT THE REDUCED FATIGUE WAS ASSOCIATED WITH DECREASED SERUM TNF-ALPHA LEVEL AND TAS-20 SCORES, FATIGUE IMPROVEMENT MIGHT BE RELATED TO REDUCED INFLAMMATION AND IMPROVED ALEXITHYMIA IN THESE PATIENTS.

3 1523  75 ISOMETRIC YOGA IMPROVES THE FATIGUE AND PAIN OF PATIENTS WITH CHRONIC FATIGUE SYNDROME WHO ARE RESISTANT TO CONVENTIONAL THERAPY: A RANDOMIZED, CONTROLLED TRIAL. BACKGROUND: PATIENTS WITH CHRONIC FATIGUE SYNDROME (CFS) OFTEN COMPLAIN OF PERSISTENT FATIGUE EVEN AFTER CONVENTIONAL THERAPIES SUCH AS PHARMACOTHERAPY, COGNITIVE BEHAVIORAL THERAPY, OR GRADED EXERCISE THERAPY. THE AIM OF THIS STUDY WAS TO INVESTIGATE IN A RANDOMIZED, CONTROLLED TRIAL THE FEASIBILITY AND EFFICACY OF ISOMETRIC YOGA IN PATIENTS WITH CFS WHO ARE RESISTANT TO CONVENTIONAL TREATMENTS. METHODS: THIS TRIAL ENROLLED 30 PATIENTS WITH CFS WHO DID NOT HAVE SATISFACTORY IMPROVEMENT AFTER RECEIVING CONVENTIONAL THERAPY FOR AT LEAST SIX MONTHS. THEY WERE RANDOMLY DIVIDED INTO TWO GROUPS AND WERE TREATED WITH EITHER CONVENTIONAL PHARMACOTHERAPY (CONTROL GROUP, N = 15) OR CONVENTIONAL THERAPY TOGETHER WITH ISOMETRIC YOGA PRACTICE THAT CONSISTED OF BIWEEKLY, 20-MINUTE SESSIONS WITH A YOGA INSTRUCTOR AND DAILY IN-HOME SESSIONS (YOGA GROUP, N = 15) FOR APPROXIMATELY TWO MONTHS. THE SHORT-TERM EFFECT OF ISOMETRIC YOGA ON FATIGUE WAS ASSESSED BY ADMINISTRATION OF THE PROFILE OF MOOD STATUS (POMS) QUESTIONNAIRE IMMEDIATELY BEFORE AND AFTER THE FINAL 20-MINUTE SESSION WITH THE INSTRUCTOR. THE LONG-TERM EFFECT OF ISOMETRIC YOGA ON FATIGUE WAS ASSESSED BY ADMINISTRATION OF THE CHALDER'S FATIGUE SCALE (FS) QUESTIONNAIRE TO BOTH GROUPS BEFORE AND AFTER THE INTERVENTION. ADVERSE EVENTS AND CHANGES IN SUBJECTIVE SYMPTOMS WERE RECORDED FOR SUBJECTS IN THE YOGA GROUP. RESULTS: ALL SUBJECTS COMPLETED THE INTERVENTION. THE MEAN POMS FATIGUE SCORE DECREASED SIGNIFICANTLY (FROM 21.9 +/- 7.7 TO 13.8 +/- 6.7, P < 0.001) AFTER A YOGA SESSION. THE CHALDER'S FS SCORE DECREASED SIGNIFICANTLY (FROM 25.9 +/- 6.1 TO 19.2 +/- 7.5, P = 0.002) IN THE YOGA GROUP, BUT NOT IN THE CONTROL GROUP. IN ADDITION TO THE IMPROVEMENT OF FATIGUE, TWO PATIENTS WITH CFS AND FIBROMYALGIA SYNDROME IN THE YOGA GROUP ALSO REPORTED PAIN RELIEF. FURTHERMORE, MANY SUBJECTS REPORTED THAT THEIR BODIES BECAME WARMER AND LIGHTER AFTER PRACTICING ISOMETRIC YOGA. ALTHOUGH THERE WERE NO SERIOUS ADVERSE EVENTS IN THE YOGA GROUP, TWO PATIENTS COMPLAINED OF TIREDNESS AND ONE OF DIZZINESS AFTER THE FIRST YOGA SESSION WITH THE INSTRUCTOR. CONCLUSIONS: ISOMETRIC YOGA AS AN ADD-ON THERAPY IS BOTH FEASIBLE AND SUCCESSFUL AT RELIEVING THE FATIGUE AND PAIN OF A SUBSET OF THERAPY-RESISTANT PATIENTS WITH CFS.

4  610  61 DEVELOPMENT OF A RECUMBENT ISOMETRIC YOGA PROGRAM FOR PATIENTS WITH SEVERE CHRONIC FATIGUE SYNDROME/MYALGIC ENCEPHALOMYELITIS: A PILOT STUDY TO ASSESS FEASIBILITY AND EFFICACY. BACKGROUND: OUR PREVIOUS RANDOMIZED CONTROLLED TRIAL DEMONSTRATED THAT ISOMETRIC YOGA IN A SITTING POSITION REDUCES FATIGUE IN PATIENTS WITH CHRONIC FATIGUE SYNDROME/MYALGIC ENCEPHALOMYELITIS (CFS/ME). HOWEVER, SOME PATIENTS EXPERIENCE DIFFICULTIES SITTING OR PRACTICING ISOMETRIC YOGA IN A SITTING POSITION FOR LONG PERIODS. TO DATE, THERAPEUTIC INTERVENTIONS FOR PATIENTS WITH SEVERE SYMPTOMS HAVE NOT BEEN ESTABLISHED. THEREFORE, WE DEVELOPED A RECUMBENT ISOMETRIC YOGA PROGRAM, WHICH TAKES APPROXIMATELY 20 MIN TO COMPLETE, DESIGNED TO REDUCE FATIGUE IN PATIENTS WITH SEVERE CFS/ME. THE AIM OF THIS PILOT STUDY WAS TO ASSESS THE FEASIBILITY, SAFETY, AND USEFULNESS OF THIS PROGRAM. METHODS: THIS PILOT STUDY INCLUDED 12 ADULT PATIENTS WITH CFS/ME. SIX PATIENTS WERE RELUCTANT TO PRACTICE ISOMETRIC YOGA IN A SITTING POSITION BECAUSE OF THE SEVERITY OF THEIR FATIGUE (GROUP 1). THE REMAINING SIX PATIENTS HAD PREVIOUSLY PRACTICED ISOMETRIC YOGA IN A SITTING POSITION (GROUP 2). FOR 3 MONTHS, THE PATIENTS OF BOTH GROUPS PRACTICED RECUMBENT ISOMETRIC YOGA EVERY 2 TO 4 WEEKS WITH A YOGA INSTRUCTOR AND AT HOME ON OTHER DAYS IF THEY COULD. THE SHORT-TERM EFFECTS OF ISOMETRIC YOGA ON FATIGUE WERE ASSESSED USING THE PROFILE OF MOOD STATUS (POMS) QUESTIONNAIRE IMMEDIATELY BEFORE AND AFTER THEIR FINAL SESSION WITH THE YOGA INSTRUCTOR. THE LONG-TERM EFFECTS OF ISOMETRIC YOGA ON FATIGUE WERE ASSESSED USING THE CHALDER FATIGUE SCALE (FS) QUESTIONNAIRE BEFORE AND AFTER THE INTERVENTION PERIOD. ADVERSE EVENTS, SATISFACTION WITH THE PROGRAM, AND PREFERENCE OF YOGA POSITION (SITTING OR RECUMBENT) WERE ALSO RECORDED. RESULTS: ALL SUBJECTS COMPLETED THE INTERVENTION. IN BOTH GROUPS, THE POMS FATIGUE SCORE WAS SIGNIFICANTLY DECREASED AFTER PRACTICING THE 20-MIN YOGA PROGRAM AND THE CHALDER FS SCORE WAS DECREASED SIGNIFICANTLY AFTER THE 3-MONTH INTERVENTION PERIOD. THERE WERE NO SERIOUS ADVERSE EVENTS. ALL SUBJECTS IN GROUP 2 PREFERRED THE RECUMBENT ISOMETRIC YOGA PROGRAM OVER A SITTING YOGA PROGRAM. CONCLUSIONS: THIS STUDY SUGGESTS THAT RECUMBENT ISOMETRIC YOGA IS A FEASIBLE AND ACCEPTABLE TREATMENT FOR PATIENTS WITH CFS/ME, EVEN FOR PATIENTS WHO EXPERIENCE DIFFICULTY PRACTICING ISOMETRIC YOGA IN THE SITTING POSITION.	2017	
                                                                                                                                                                                                                                                                                                                                                         
5 1318  49 HEART RATE VARIABILITY IN CHRONIC LOW BACK PAIN PATIENTS RANDOMIZED TO YOGA OR STANDARD CARE. BACKGROUND: CHRONIC PAIN CAN ALTER THE AUTONOMIC BALANCE WITH INCREASED SYMPATHETIC ACTIVITY REFLECTED IN ALTERED HEART RATE VARIABILITY (HRV). IT HAS BEEN PROPOSED THAT YOGA CAN BE USEFUL TO CORRECT THE AUTONOMIC IMBALANCE IN PATIENTS WITH CHRONIC PAIN WHO HAVE REDUCED HRV. METHODS AND DESIGNS: IN THE PRESENT RANDOMIZED CONTROLLED TRIAL 62 PATIENTS WITH CHRONIC LOW BACK PAIN ASSOCIATED WITH ALTERED ALIGNMENT OF INTERVERTEBRAL DISCS (AGED BETWEEN 20 AND 45 YEARS, 32 MALES) WERE RANDOMIZED TO 2 GROUPS. ONE GROUP RECEIVED YOGA FOR 3 MONTHS WHILE THE OTHER GROUP CARRIED OUT STANDARD MEDICAL CARE BASED ON THE PHYSICIAN'S ADVICE. THE DURATION WAS THE SAME, I.E., 3 MONTHS. THE HEART RATE VARIABILITY AND RATE OF RESPIRATION WERE ASSESSED AT BASELINE AND AT THE END OF 3 MONTHS. RESULTS: THERE WAS A SIGNIFICANT DIFFERENCE IN THE BASELINE (PRE) VALUES BETWEEN GROUPS (P = 0.008) FOR RESPIRATION RATE WHICH WAS HIGHER IN THE YOGA GROUP. THE CHANGES REPORTED BELOW ARE PRE-POST COMPARISONS WITHIN EACH GROUP. THE YOGA GROUP SHOWED A SIGNIFICANT (P < 0.05; REPEATED MEASURES ANOVA, POST-HOC ANALYSES) DECREASE IN THE LF POWER OF HRV, RATE OF RESPIRATION AND A SIGNIFICANT INCREASE IN THE HF POWER OF HRV AND IN THE PNN50. CONCLUSION: THE RESULTS SUGGEST THAT YOGA PRACTICE CAN SHIFT THE AUTONOMIC BALANCE TOWARDS VAGAL DOMINANCE IN PATIENTS WITH CHRONIC LOW BACK PAIN ASSOCIATED WITH ALTERED ALIGNMENT OF INTERVERTEBRAL DISCS.

6  661  62 EFFECT OF 12 WEEKS OF YOGA TRAINING ON THE SOMATIZATION, PSYCHOLOGICAL SYMPTOMS, AND STRESS-RELATED BIOMARKERS OF HEALTHY WOMEN. BACKGROUND: PREVIOUS STUDIES HAVE SHOWN THAT THE PRACTICE OF YOGA REDUCES PERCEIVED STRESS AND NEGATIVE FEELINGS AND THAT IT IMPROVES PSYCHOLOGICAL SYMPTOMS. OUR PREVIOUS STUDY ALSO SUGGESTED THAT LONG-TERM YOGA TRAINING IMPROVES STRESS-RELATED PSYCHOLOGICAL SYMPTOMS SUCH AS ANXIETY AND ANGER. HOWEVER, LITTLE IS KNOWN ABOUT THE BENEFICIAL EFFECTS OF YOGA PRACTICE ON SOMATIZATION, THE MOST COMMON STRESS-RELATED PHYSICAL SYMPTOMS, AND STRESS-RELATED BIOMARKERS. WE PERFORMED A PROSPECTIVE, SINGLE ARM STUDY TO EXAMINE THE BENEFICIAL EFFECTS OF 12 WEEKS OF YOGA TRAINING ON SOMATIZATION, PSYCHOLOGICAL SYMPTOMS, AND STRESS-RELATED BIOMARKERS. METHODS: WE RECRUITED HEALTHY WOMEN WHO HAD NO EXPERIENCE WITH YOGA. THE DATA OF 24 PARTICIPANTS WHO WERE FOLLOWED DURING 12 WEEKS OF YOGA TRAINING WERE ANALYZED. SOMATIZATION AND PSYCHOLOGICAL SYMPTOMS WERE ASSESSED BEFORE AND AFTER 12 WEEKS OF YOGA TRAINING USING THE PROFILE OF MOOD STATE (POMS) AND THE SYMPTOM CHECKLIST-90-REVISED (SCL-90-R) QUESTIONNAIRES. URINARY 8-HYDROXYDEOXYGUANOSINE (8-OHDG), BIOPYRRIN, AND CORTISOL LEVELS WERE MEASURED AS STRESS-RELATED BIOMARKERS. THE WILCOXON SIGNED-RANK TEST WAS USED TO COMPARE THE STRESS-RELATED BIOMARKERS AND THE SCORES OF QUESTIONNAIRES BEFORE AND AFTER 12 WEEKS OF YOGA TRAINING. RESULTS: AFTER 12 WEEKS OF YOGA TRAINING, ALL NEGATIVE SUBSCALE SCORES (TENSION-ANXIETY, DEPRESSION, ANGER-HOSTILITY, FATIGUE, AND CONFUSION) FROM THE POMS AND SOMATIZATION, ANXIETY, DEPRESSION, AND HOSTILITY FROM THE SCL-90-R WERE SIGNIFICANTLY DECREASED COMPARED WITH THOSE BEFORE STARTING YOGA TRAINING. CONTRARY TO OUR EXPECTATION, THE URINARY 8-OHDG CONCENTRATION AFTER 12 WEEKS OF YOGA TRAINING SHOWED A SIGNIFICANT INCREASE COMPARED WITH THAT BEFORE STARTING YOGA TRAINING. NO SIGNIFICANT CHANGES WERE OBSERVED IN THE LEVELS OF URINARY BIOPYRRIN AND CORTISOL AFTER THE 12 WEEKS OF YOGA TRAINING. CONCLUSIONS: YOGA TRAINING HAS THE POTENTIAL TO REDUCE THE SOMATIZATION SCORE AND THE SCORES RELATED TO MENTAL HEALTH INDICATORS, SUCH AS ANXIETY, DEPRESSION, ANGER, AND FATIGUE. THE PRESENT FINDINGS SUGGEST THAT YOGA CAN IMPROVE SOMATIZATION AND MENTAL HEALTH STATUS AND HAS IMPLICATIONS FOR THE PREVENTION OF PSYCHOSOMATIC SYMPTOMS IN HEALTHY WOMEN.

7  835  40 EFFECT OF YOGA ON PAIN, BRAIN-DERIVED NEUROTROPHIC FACTOR, AND SEROTONIN IN PREMENOPAUSAL WOMEN WITH CHRONIC LOW BACK PAIN. BACKGROUND. SEROTONIN AND BRAIN-DERIVED NEUROTROPHIC FACTOR (BDNF) ARE KNOWN TO BE MODULATORS OF NOCICEPTION. HOWEVER, PAIN-RELATED CONNECTION BETWEEN YOGA AND THOSE NEUROMODULATORS HAS NOT BEEN INVESTIGATED. THEREFORE, WE AIMED TO EVALUATE THE EFFECT OF YOGA ON PAIN, BDNF, AND SEROTONIN. METHODS. PREMENOPAUSAL WOMEN WITH CHRONIC LOW BACK PAIN PRACTICED YOGA THREE TIMES A WEEK FOR 12 WEEKS. AT BASELINE AND AFTER 12 WEEKS, BACK PAIN INTENSITY WAS MEASURED USING VISUAL ANALOGUE SCALE (VAS), AND SERUM BDNF AND SEROTONIN LEVELS WERE EVALUATED. ADDITIONALLY, BACK FLEXIBILITY AND LEVEL OF DEPRESSION WERE ASSESSED. RESULTS. AFTER 12-WEEK YOGA, VAS DECREASED IN THE YOGA GROUP (P < 0.001), WHEREAS IT INCREASED (P < 0.05) IN THE CONTROL GROUP. BACK FLEXIBILITY WAS IMPROVED IN THE YOGA GROUP (P < 0.01). SERUM BDNF INCREASED IN THE YOGA GROUP (P < 0.01), WHEREAS IT TENDED TO DECREASE IN THE CONTROL GROUP (P = 0.05). SERUM SEROTONIN MAINTAINED IN THE YOGA GROUP, WHILE IT REDUCED (P < 0.01) IN THE CONTROL GROUP. THE DEPRESSION LEVEL MAINTAINED IN THE YOGA GROUP, WHEREAS IT TENDED TO INCREASE IN THE CONTROL GROUP (P = 0.07). CONCLUSIONS. WE PROPOSE THAT BDNF MAY BE ONE OF THE KEY FACTORS MEDIATING BENEFICIAL EFFECTS OF YOGA ON CHRONIC LOW BACK PAIN.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
8  716  41 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
9 1063  36 EFFECTS OF YOGA ON HEART RATE VARIABILITY AND MOOD IN WOMEN: A RANDOMIZED CONTROLLED TRIAL. OBJECTIVE: TO EXAMINE THE EFFECTS OF AN 8-WEEK YOGA PROGRAM ON HEART RATE VARIABILITY AND MOOD IN GENERALLY HEALTHY WOMEN. DESIGN: RANDOMIZED CONTROLLED TRIAL. PARTICIPANTS: FIFTY-TWO HEALTHY WOMEN WERE RANDOMLY ASSIGNED TO A YOGA GROUP OR A CONTROL GROUP. INTERVENTIONS: PARTICIPANTS IN THE YOGA GROUP COMPLETED AN 8-WEEK YOGA PROGRAM, WHICH COMPRISED A 60-MINUTE SESSION TWICE A WEEK. EACH SESSION CONSISTED OF BREATHING EXERCISES, YOGA POSE PRACTICE, AND SUPINE MEDITATION/RELAXATION. THE CONTROL GROUP WAS INSTRUCTED NOT TO ENGAGE IN ANY YOGA PRACTICE AND TO MAINTAIN THEIR USUAL LEVEL OF PHYSICAL ACTIVITY DURING THE STUDY. OUTCOME MEASURES: PARTICIPANTS' HEART RATE VARIABILITY, PERCEIVED STRESS, DEPRESSIVE SYMPTOMS, AND STATE AND TRAIT ANXIETY WERE ASSESSED AT BASELINE (WEEK 0) AND AFTER THE INTERVENTION (WEEK 9). RESULTS: NO MEASURES OF HEART RATE VARIABILITY CHANGED SIGNIFICANTLY IN EITHER THE YOGA OR CONTROL GROUP AFTER INTERVENTION. STATE ANXIETY WAS REDUCED SIGNIFICANTLY IN THE YOGA GROUP BUT NOT IN THE CONTROL GROUP. NO SIGNIFICANT CHANGES WERE NOTED IN PERCEIVED STRESS, DEPRESSION, OR TRAIT ANXIETY IN EITHER GROUP. CONCLUSIONS: AN 8-WEEK YOGA PROGRAM WAS NOT SUFFICIENT TO IMPROVE HEART RATE VARIABILITY. HOWEVER, SUCH A PROGRAM APPEARS TO BE EFFECTIVE IN REDUCING STATE ANXIETY IN GENERALLY HEALTHY WOMEN. FUTURE RESEARCH SHOULD INVOLVE LONGER PERIODS OF YOGA TRAINING, INCLUDE HEART RATE VARIABILITY MEASURES BOTH AT REST AND DURING YOGA PRACTICE, AND ENROLL WOMEN WITH HIGHER LEVELS OF STRESS AND TRAIT ANXIETY.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
10 1967  36 SERUM CORTISOL AND BDNF IN PATIENTS WITH MAJOR DEPRESSION-EFFECT OF YOGA. DEPRESSION IS ASSOCIATED WITH LOW SERUM BRAIN DERIVED NEUROTROPHIC FACTOR (BDNF) AND ELEVATED LEVELS OF SERUM CORTISOL. YOGA PRACTICES HAVE BEEN ASSOCIATED WITH ANTIDEPRESSANT EFFECTS, INCREASE IN SERUM BDNF, AND REDUCTION IN SERUM CORTISOL. THIS STUDY EXAMINED THE ASSOCIATION BETWEEN SERUM BDNF AND CORTISOL LEVELS IN DRUG-NAIVE PATIENTS WITH DEPRESSION TREATED WITH ANTIDEPRESSANTS, YOGA THERAPY, AND BOTH. FIFTY-FOUR DRUG-NAIVE CONSENTING ADULT OUTPATIENTS WITH MAJOR DEPRESSION (32 MALES) RECEIVED ANTIDEPRESSANTS ONLY (N = 16), YOGA THERAPY ONLY (N = 19), OR YOGA WITH ANTIDEPRESSANTS (N = 19). SERUM BDNF ANDCORTISOL LEVELS WERE OBTAINED BEFORE AND AFTER 3 MONTHS USING A SANDWICH ELISA METHOD. ONE-WAY ANOVA, CHI-SQUARE TEST, AND PEARSON'S CORRELATION TESTS WERE USED FOR ANALYSIS. THE GROUPS WERE COMPARABLE AT BASELINE ON MOST PARAMETERS. SIGNIFICANT IMPROVEMENT IN DEPRESSION SCORES AND SERUM BDNF LEVELS, AND REDUCTION IN SERUM CORTISOL IN THE YOGA GROUPS, HAVE BEEN DESCRIBED IN PREVIOUS REPORTS. A SIGNIFICANT NEGATIVE CORRELATION WAS OBSERVED BETWEEN CHANGE IN BDNF (PRE-POST) AND CORTISOL (PRE-POST) LEVELS IN THE YOGA-ONLY GROUP (R = -0.59, P = 0.008). IN CONCLUSION, YOGA MAY FACILITATE NEUROPLASTICITY THROUGH STRESS REDUCTION IN DEPRESSED PATIENTS. FURTHER STUDIES ARE NEEDED TO CONFIRM THE FINDINGS AND DELINEATE THE PATHWAYS FOR THESE EFFECTS.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
11 1062  42 EFFECTS OF YOGA ON HEART RATE VARIABILITY AND DEPRESSIVE SYMPTOMS IN WOMEN: A RANDOMIZED CONTROLLED TRIAL. OBJECTIVES: THE PURPOSE OF THE STUDY WAS TO INVESTIGATE THE EFFECTS OF A 12-WEEK YOGA PROGRAM ON HEART RATE VARIABILITY (HRV) AND DEPRESSIVE SYMPTOMS IN DEPRESSED WOMEN. METHODS: THIS WAS A RANDOMIZED CONTROLLED TRIAL. TWENTY-SIX SEDENTARY WOMEN SCORING >/=14 ON THE BECK DEPRESSION INVENTORY-II WERE RANDOMIZED TO EITHER THE YOGA OR THE CONTROL GROUP. THE YOGA GROUP COMPLETED A 12-WEEK YOGA PROGRAM, WHICH TOOK PLACE TWICE A WEEK FOR 60 MIN PER SESSION AND CONSISTED OF BREATHING EXERCISES, YOGA POSE PRACTICE, AND SUPINE MEDITATION/RELAXATION. THE CONTROL GROUP WAS INSTRUCTED NOT TO ENGAGE IN ANY YOGA PRACTICE AND TO MAINTAIN THEIR USUAL LEVEL OF PHYSICAL ACTIVITY DURING THE COURSE OF THE STUDY. PARTICIPANTS' HRV, DEPRESSIVE SYMPTOMS, AND PERCEIVED STRESS WERE ASSESSED AT BASELINE AND POST-TEST. RESULTS: THE YOGA GROUP HAD A SIGNIFICANT INCREASE IN HIGH-FREQUENCY HRV AND DECREASES IN LOW-FREQUENCY HRV AND LOW FREQUENCY/HIGH FREQUENCY RATIO AFTER THE INTERVENTION. THE YOGA GROUP ALSO REPORTED SIGNIFICANTLY REDUCED DEPRESSIVE SYMPTOMS AND PERCEIVED STRESS. NO CHANGE WAS FOUND IN THE CONTROL GROUP. CONCLUSIONS: A 12-WEEK YOGA PROGRAM WAS EFFECTIVE IN INCREASING PARASYMPATHETIC TONE AND REDUCING DEPRESSIVE SYMPTOMS AND PERCEIVED STRESS IN WOMEN WITH ELEVATED DEPRESSIVE SYMPTOMS. REGULAR YOGA PRACTICE MAY BE RECOMMENDED FOR WOMEN TO COPE WITH THEIR DEPRESSIVE SYMPTOMS AND STRESS AND TO IMPROVE THEIR HRV.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
12  859  35 EFFECT OF YOGA PRACTICE ON LEVELS OF INFLAMMATORY MARKERS AFTER MODERATE AND STRENUOUS EXERCISE. BACKGROUND AND OBJECTIVES: TO EVALUATE THE EFFECT OF YOGA PRACTICE AND EXERCISE CHALLENGE ON TUMOUR NECROSIS FACTOR ALPHA (TNF-ALPHA), INTERLEUKIN-6 (IL-6) LEVELS AND LIPID PROFILE. MATERIALS AND METHODS: TWO HUNDRED AND EIGHTEEN SUBJECTS PARTICIPATED IN THE STUDY. ONE HUNDRED AND NINE VOLUNTEERS (51 MALES AND 58 FEMALES) IN THE AGE GROUP OF 20 TO 60 YEARS, WHO PRACTICED YOGA REGULARLY FOR OVER FIVE YEARS FOR A PERIOD OF ONE HOUR DAILY, PERFORMED A BOUT OF MODERATE EXERCISE AND A BOUT OF STRENUOUS EXERCISE AS PER STANDARDIZED SHUTTLE WALK TEST PROTOCOL. ANTHROPOMETRICALLY MATCHED, AGE MATCHED AND GENDER MATCHED SUBJECTS, WHO DID NOT PRACTICE YOGA (NON-YOGA GROUP) WERE CHOSEN AS CONTROLS (NON-YOGA, N=109). THE NON-YOGA GROUP ALSO PERFORMED SIMILAR EXERCISES. THE BLOOD SAMPLES OF BOTH THE GROUPS WERE COLLECTED BEFORE AND AFTER THE EXERCISES. TNF-ALPHA AND IL-6 WAS ANALYSED BEFORE AND AFTER THE EXERCISE BY SANDWICH ELISA (ENZYME LINKED IMMUNOSORBENT ASSAY). RESULTS: RESTING PLASMA TNF-ALPHA CONCENTRATION WAS SIGNIFICANTLY HIGHER IN NON-YOGA GROUP WHEN COMPARED TO YOGA GROUP (P<0.05). THERE WAS AN INCREASE IN TNF-ALPHA LEVELS IN BOTH THE GROUPS IN RESPONSE TO STRENUOUS EXERCISE. THERE WAS NO GENDER DIFFERENCE IN TNF-ALPHA AND IL-6 LEVELS BEFORE AND AFTER EXERCISE IN YOGA AND NON-YOGA GROUPS. CONCLUSION: REGULAR PRACTICE OF YOGA LOWERS BASAL TNF-ALPHA AND IL-6 LEVELS. IT ALSO REDUCES THE EXTENT OF INCREASE OF TNF-ALPHA AND IL-6 TO A PHYSICAL CHALLENGE OF MODERATE EXERCISE AND STRENUOUS EXERCISE. THERE IS NO SIGNIFICANT GENDER DIFFERENCE IN THE TNF-ALPHA AND IL-6 LEVELS. REGULAR PRACTICE OF YOGA CAN PROTECT THE INDIVIDUAL AGAINST INFLAMMATORY DISEASES BY FAVOURABLY ALTERING PRO-INFLAMMATORY CYTOKINE LEVELS.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
13  871  49 EFFECT OF YOGA THERAPY ON DISEASE ACTIVITY, INFLAMMATORY MARKERS, AND HEART RATE VARIABILITY IN PATIENTS WITH RHEUMATOID ARTHRITIS. BACKGROUND: RHEUMATOID ARTHRITIS (RA) IS AN IMMUNE-MEDIATED INFLAMMATORY DISEASE. ANTIRHEUMATOID TREATMENT REDUCES DISEASE ACTIVITY AND INFLAMMATION, BUT NOT ALL PATIENTS RESPOND TO TREATMENT. AUTONOMIC DYSFUNCTION IS COMMON IN RA LEADING TO FREQUENT CARDIOVASCULAR COMPLICATIONS. YOGA THERAPY MAY BE USEFUL IN THESE PATIENTS, BUT THERE ARE LITTLE DATA ON THE EFFECT OF YOGA ON DISEASE ACTIVITY, INFLAMMATORY MARKERS, AND HEART RATE VARIABILITY (HRV). OBJECTIVES: THIS STUDY ASSESSED THE EFFECT OF 12-WEEK YOGA THERAPY ON DISEASE ACTIVITY, INFLAMMATORY MARKERS, AND HRV IN PATIENTS WITH RA. MATERIALS AND METHODS: THIS RANDOMIZED CONTROL TRIAL WAS CONDUCTED ON NEWLY DIAGNOSED RA PATIENTS ATTENDING OUTPATIENT SERVICES AT THE DEPARTMENT OF CLINICAL IMMUNOLOGY, JIPMER. ONE HUNDRED AND SIXTY-SIX PARTICIPANTS WERE RANDOMIZED INTO TWO GROUPS: THE CONTROL GROUP (CG) (N = 83) AND YOGA GROUP (YG) (N = 83). YOGA THERAPY WAS ADMINISTERED TO PARTICIPANTS IN THE YG FOR 12 WEEKS, ALONG WITH STANDARD MEDICAL TREATMENT. THE CG RECEIVED ONLY STANDARD MEDICAL TREATMENT. PRIMARY OUTCOMES WERE DISEASE ACTIVITY SCORE 28, INTERLEUKIN-1ALPHA (IL-1ALPHA), IL-6, TUMOR NECROSIS FACTOR-ALPHA (TNF-ALPHA), CORTISOL, AND HRV PARAMETERS. ALL PARAMETERS WERE MEASURED AT BASELINE AND AFTER 12 WEEKS. RESULTS: DISEASE ACTIVITY SIGNIFICANTLY DECREASED IN BOTH GROUPS AFTER 12 WEEKS, BUT IT WAS REDUCED MORE IN YG, WHICH WAS STATISTICALLY SIGNIFICANT (P < 0.05). IN BOTH YG AND CG, IL-1ALPHA, IL-6, TNF-ALPHA, AND CORTISOL DECREASED AFTER 12 WEEKS, BUT IL-1ALPHA AND CORTISOL DECREASED MORE SIGNIFICANTLY IN YG THAN IN CG. LOW-FREQUENCY COMPONENT EXPRESSED AS NORMALIZED UNIT (LFNU) AND THE LOW-FREQUENCY/HIGH-FREQUENCY (LF-HF) RATIO DECREASED SIGNIFICANTLY, AND TOTAL POWER AND HF COMPONENT EXPRESSED AS NORMALIZED UNIT (HFNU) INCREASED SIGNIFICANTLY IN THE YG COMPARED WITH CG. CONCLUSION: TWELVE-WEEK YOGA THERAPY, IF GIVEN ALONG WITH STANDARD MEDICAL TREATMENT, SIGNIFICANTLY REDUCES DISEASE ACTIVITY AND IMPROVES SYMPATHOVAGAL BALANCE IN RA PATIENTS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
14 1811  44 PROFILE OF MOOD STATES AND STRESS-RELATED BIOCHEMICAL INDICES IN LONG-TERM YOGA PRACTITIONERS. BACKGROUND: PREVIOUS STUDIES HAVE SHOWN THE SHORT-TERM OR INTERMEDIATE-TERM PRACTICE OF YOGA TO BE USEFUL FOR AMELIORATING SEVERAL MENTAL DISORDERS AND PSYCHOSOMATIC DISORDERS. HOWEVER, LITTLE IS KNOWN ABOUT THE LONG-TERM INFLUENCES OF YOGA ON THE MENTAL STATE OR STRESS-RELATED BIOCHEMICAL INDICES. IF YOGA TRAINING HAS A STRESS-REDUCTION EFFECT AND ALSO IMPROVES AN INDIVIDUAL'S MENTAL STATES FOR A LONG TIME, LONG-TERM YOGA PRACTITIONERS MAY HAVE A BETTER MENTAL STATE AND LOWER STRESS-RELATED BIOCHEMICAL INDICES IN COMPARISON TO NON-EXPERIENCED PARTICIPANTS. THIS STUDY SIMULTANEOUSLY EXAMINED THE DIFFERENCES IN MENTAL STATES AND URINARY STRESS-RELATED BIOCHEMICAL INDICES BETWEEN LONG-TERM YOGA PRACTITIONERS AND NON-EXPERIENCED PARTICIPANTS. METHODS: THE PARTICIPANTS WERE 38 HEALTHY FEMALES WITH MORE THAN 2 YEARS OF EXPERIENCE WITH YOGA (LONG-TERM YOGA GROUP) AND 37 AGE-MATCHED HEALTHY FEMALES WHO HAD NOT PARTICIPATED IN YOGA (CONTROL GROUP). THEIR MENTAL STATES WERE ASSESSED USING THE PROFILE OF MOOD STATES (POMS) QUESTIONNAIRE. THE LEVEL OF CORTISOL, 8-HYDROXYDEOXYGUANOSINE (8-OHDG) AND BIOPYRRIN IN URINE WERE USED AS STRESS-RELATED BIOCHEMICAL INDICES. RESULTS: THE AVERAGE SELF-RATED MENTAL DISTURBANCE, TENSION-ANXIETY, ANGER-HOSTILITY, AND FATIGUE SCORES OF THE LONG-TERM YOGA GROUP WERE LOWER THAN THOSE OF THE CONTROL GROUP. THERE WAS A TREND TOWARD A HIGHER VIGOR SCORE IN THE LONG-TERM YOGA GROUP THAN THAT IN THE CONTROL GROUP. THERE WERE NO SIGNIFICANT DIFFERENCES IN THE SCORES FOR DEPRESSION AND CONFUSION IN THE POMS BETWEEN THE TWO GROUPS. THE URINE 8-OHDG CONCENTRATION SHOWED A TREND TOWARD TO BEING LOWER IN THE LONG-TERM YOGA GROUP IN COMPARISON TO THE CONTROL GROUP. THERE WERE NO SIGNIFICANT DIFFERENCES IN THE LEVELS OF URINE BIOPYRRIN OR CORTISOL. CONCLUSIONS: THE PRESENT FINDINGS SUGGEST THAT LONG-TERM YOGA TRAINING CAN REDUCE THE SCORES RELATED TO MENTAL HEALTH INDICATORS SUCH AS SELF-RATED ANXIETY, ANGER, AND FATIGUE.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
15 2863  33 YOGA-BASED GUIDED RELAXATION REDUCES SYMPATHETIC ACTIVITY JUDGED FROM BASELINE LEVELS. 35 MALE VOLUNTEERS WHOSE AGES RANGED FROM 20 TO 46 YEARS WERE STUDIED IN TWO SESSIONS OF YOGA-BASED GUIDED RELAXATION AND SUPINE REST. ASSESSMENTS OF AUTONOMIC VARIABLES WERE MADE FOR 15 SUBJECTS, BEFORE, DURING, AND AFTER THE PRACTICES, WHEREAS OXYGEN CONSUMPTION AND BREATH VOLUME WERE RECORDED FOR 25 SUBJECTS BEFORE AND AFTER BOTH TYPES OF RELAXATION. A SIGNIFICANT DECREASE IN OXYGEN CONSUMPTION AND INCREASE IN BREATH VOLUME WERE RECORDED AFTER GUIDED RELAXATION (PAIRED T TEST). THERE WERE COMPARABLE REDUCTIONS IN HEART RATE AND SKIN CONDUCTANCE DURING BOTH TYPES OF RELAXATION. DURING GUIDED RELAXATION THE POWER OF THE LOW FREQUENCY COMPONENT OF THE HEART-RATE VARIABILITY SPECTRUM REDUCED, WHEREAS THE POWER OF THE HIGH FREQUENCY COMPONENT INCREASED, SUGGESTING REDUCED SYMPATHETIC ACTIVITY. ALSO, SUBJECTS WITH A BASELINE RATIO OF LF/HF > 0.5 SHOWED A SIGNIFICANT DECREASE IN THE RATIO AFTER GUIDED RELAXATION, WHILE SUBJECTS WITH A RATIO < OR = 0.5 AT BASELINE SHOWED NO SUCH CHANGE. THE RESULTS SUGGEST THAT SYMPATHETIC ACTIVITY DECREASED AFTER GUIDED RELAXATION BASED ON YOGA, DEPENDING ON THE BASELINE LEVELS.	2002	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
16 1402  49 IMPACT OF YOGA ON BLOOD PRESSURE AND QUALITY OF LIFE IN PATIENTS WITH HYPERTENSION - A CONTROLLED TRIAL IN PRIMARY CARE, MATCHED FOR SYSTOLIC BLOOD PRESSURE. BACKGROUND: MEDICAL TREATMENT OF HYPERTENSION IS NOT ALWAYS SUFFICIENT TO ACHIEVE BLOOD PRESSURE CONTROL. DESPITE THIS, PREVIOUS STUDIES ON SUPPLEMENTARY THERAPIES, SUCH AS YOGA, ARE RELATIVELY FEW. WE INVESTIGATED THE EFFECTS OF TWO YOGA INTERVENTIONS ON BLOOD PRESSURE AND QUALITY OF LIFE IN PATIENTS IN PRIMARY HEALTH CARE DIAGNOSED WITH HYPERTENSION. METHODS: ADULT PATIENTS (AGE 20-80 YEARS) WITH DIAGNOSED HYPERTENSION WERE IDENTIFIED BY AN ELECTRONIC CHART SEARCH AT A PRIMARY HEALTH CARE CENTER IN SOUTHERN SWEDEN. IN TOTAL, 83 SUBJECTS WITH BLOOD PRESSURE VALUES OF 120-179/</=109 MMHG AT BASELINE WERE ENROLLED. AT BASELINE, THE PATIENTS UNDERWENT STANDARDIZED BLOOD PRESSURE MEASUREMENT AT THE HEALTH CARE CENTER AND THEY COMPLETED A QUESTIONNAIRE ON SELF-RATED QUALITY OF LIFE (WHOQOL-BREF). THERE WERE THREE GROUPS: 1) YOGA CLASS WITH YOGA INSTRUCTOR (N = 28); 2) YOGA AT HOME (N = 28); AND 3) A CONTROL GROUP (N = 27). THE PARTICIPANTS WERE MATCHED AT THE GROUP LEVEL FOR SYSTOLIC BLOOD PRESSURE. AFTER 12 WEEKS OF INTERVENTION, THE ASSESSMENTS WERE PERFORMED AGAIN. AT BASELINE A MAJORITY OF THE PATIENTS (92%) WERE ON ANTIHYPERTENSIVE MEDICATION, AND THE PATIENTS WERE REQUESTED NOT TO CHANGE THEIR MEDICATION DURING THE STUDY. RESULTS: THE YOGA CLASS GROUP SHOWED NO IMPROVEMENT IN BLOOD PRESSURE OR SELF-RATED QUALITY OF LIFE, WHILE IN THE YOGA AT HOME GROUP THERE WAS A DECLINE IN DIASTOLIC BLOOD PRESSURE OF 4.4 MMHG (P < 0.05) COMPARED TO THE CONTROL GROUP. MOREOVER, THE YOGA AT HOME GROUP SHOWED SIGNIFICANT IMPROVEMENT IN SELF-RATED QUALITY OF LIFE COMPARED TO THE CONTROL GROUP (P < 0.05). CONCLUSIONS: A SHORT YOGA PROGRAM FOR THE PATIENT TO PRACTICE AT HOME SEEMS TO HAVE AN ANTIHYPERTENSIVE EFFECT, AS WELL AS A POSITIVE EFFECT ON SELF-RATED QUALITY OF LIFE COMPARED TO CONTROLS. THIS IMPLIES THAT SIMPLE YOGA EXERCISES MAY BE USEFUL AS A SUPPLEMENTARY BLOOD PRESSURE THERAPY IN ADDITION TO MEDICAL TREATMENT WHEN PRESCRIBED BY PRIMARY CARE PHYSICIANS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
17 1102  37 EFFECTS OF YOGA TRAINING ON BODY COMPOSITION AND OXIDANT-ANTIOXIDANT STATUS AMONG HEALTHY MALE. BACKGROUND: THE STRESSFUL CONDITION MAY CAUSE OXIDATIVE STRESS, WHICH IS RESPONSIBLE FOR VARIOUS DISEASES. AIMS: THE PRESENT STUDY WAS DESIGNED TO FIND OUT WHETHER YOGA HAS IMPACT ON THE REDUCTION OF OXIDATIVE STRESS. METHODS: FOR THE PRESENT STUDY, 95 (N = 95) HEALTHY MALE VOLUNTEERS WITHIN THE AGE GROUP OF 18-24 YEARS WERE INCLUDED, 35 (N = 35) VOLUNTEERS WERE EXCLUDED. THE REMAINING 60 (N = 60) VOLUNTEERS WERE RANDOMLY DIVIDED INTO TWO GROUPS: (A) YOGA GROUP (N = 30) AND (B) CONTROL GROUP (N = 30). YOGA TRAINING WAS GIVEN FOR 60 MIN PER DAY, 6 DAYS PER WEEK FOR 12 WEEKS IN THE YOGA GROUP, WITH NO YOGA TRAINING IN CONTROL GROUP. ASSESSMENT OF BODY COMPOSITION AND OXIDANT-ANTIOXIDANT STATUS WERE PERFORMED IN BOTH THE GROUPS AT BASELINE, BEFORE YOGA TRAINING (0 WEEK) AND AFTER (12 WEEKS) OF THE TRAINING. RESULTS: SIGNIFICANT REDUCTION (P < 0.001) IN THE PERCENTAGE OF BODY FAT AND MALONDIALDEHYDE; SIGNIFICANT ELEVATION (P < 0.001) IN SUPEROXIDE DISMUTASE, CATALASE, REDUCED GLUTATHIONE AND ASCORBIC ACID LEVELS WERE NOTED IN THE YOGA GROUP AFTER 12 WEEKS WHEN COMPARED TO BASELINE DATA (0 WEEK). HOWEVER, THERE WAS NO SIGNIFICANT DIFFERENCE IN HEIGHT, WEIGHT, BODY MASS INDEX, BODY SURFACE AREA AND LEAN BODY MASS AMONG THE YOGA GROUP AFTER 12 WEEKS WHEN COMPARED TO BASELINE DATA. THESE CHANGES MIGHT BE DUE TO YOGA TRAINING. CONCLUSIONS: REGULAR YOGA PRACTICE REDUCES BODY FAT AND OXIDATIVE STRESS. YOGA TRAINING MAY BE HELPFUL TO REDUCE THE CHANCE OF OCCURRENCE OF VARIOUS DISEASES AND HELPS TO MAINTAIN NORMAL HEALTHY LIFESTYLE.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
18 2847  46 YOGA, MEDITATION AND MIND-BODY HEALTH: INCREASED BDNF, CORTISOL AWAKENING RESPONSE, AND ALTERED INFLAMMATORY MARKER EXPRESSION AFTER A 3-MONTH YOGA AND MEDITATION RETREAT. THIRTY-EIGHT INDIVIDUALS (MEAN AGE: 34.8 YEARS OLD) PARTICIPATING IN A 3-MONTH YOGA AND MEDITATION RETREAT WERE ASSESSED BEFORE AND AFTER THE INTERVENTION FOR PSYCHOMETRIC MEASURES, BRAIN DERIVED NEUROTROPHIC FACTOR (BDNF), CIRCADIAN SALIVARY CORTISOL LEVELS, AND PRO- AND ANTI-INFLAMMATORY CYTOKINES. PARTICIPATION IN THE RETREAT WAS FOUND TO BE ASSOCIATED WITH DECREASES IN SELF-REPORTED ANXIETY AND DEPRESSION AS WELL AS INCREASES IN MINDFULNESS. AS HYPOTHESIZED, INCREASES IN THE PLASMA LEVELS OF BDNF AND INCREASES IN THE MAGNITUDE OF THE CORTISOL AWAKENING RESPONSE (CAR) WERE ALSO OBSERVED. THE NORMALIZED CHANGE IN BDNF LEVELS WAS INVERSELY CORRELATED WITH BSI-18 ANXIETY SCORES AT BOTH THE PRE-RETREAT (R = 0.40, P < 0.05) AND POST-RETREAT (R = 0.52, P < 0.005) SUCH THAT THOSE WITH GREATER ANXIETY SCORES TENDED TO EXHIBIT SMALLER PRE- TO POST-RETREAT INCREASES IN PLASMA BDNF LEVELS. IN LINE WITH A HYPOTHESIZED DECREASE IN INFLAMMATORY PROCESSES RESULTING FROM THE YOGA AND MEDITATION PRACTICES, WE FOUND THAT THE PLASMA LEVEL OF THE ANTI-INFLAMMATORY CYTOKINE INTERLEUKIN-10 WAS INCREASED AND THE PRO-INFLAMMATORY CYTOKINE INTERLEUKIN-12 WAS REDUCED AFTER THE RETREAT. CONTRARY TO OUR INITIAL HYPOTHESES, PLASMA LEVELS OF OTHER PRO-INFLAMMATORY CYTOKINES, INCLUDING INTERFERON GAMMA (IFN-GAMMA), TUMOR NECROSIS FACTOR (TNF-ALPHA), INTERLEUKIN-1BETA (IL-1BETA), INTERLEUKIN-6 (IL-6), AND INTERLEUKIN-8 (IL-8) WERE INCREASED AFTER THE RETREAT. GIVEN EVIDENCE FROM PREVIOUS STUDIES OF THE POSITIVE EFFECTS OF MEDITATIVE PRACTICES ON MENTAL FITNESS, AUTONOMIC HOMEOSTASIS AND INFLAMMATORY STATUS, WE HYPOTHESIZE THAT THESE FINDINGS ARE RELATED TO THE MEDITATIVE PRACTICES THROUGHOUT THE RETREAT; HOWEVER, SOME OF THE OBSERVED CHANGES MAY ALSO BE RELATED TO OTHER ASPECTS OF THE RETREAT SUCH AS PHYSICAL EXERCISE-RELATED COMPONENTS OF THE YOGA PRACTICE AND DIET. WE HYPOTHESIZE THAT THE PATTERNS OF CHANGE OBSERVED HERE REFLECT MIND-BODY INTEGRATION AND WELL-BEING. THE INCREASED BDNF LEVELS OBSERVED IS A POTENTIAL MEDIATOR BETWEEN MEDITATIVE PRACTICES AND BRAIN HEALTH, THE INCREASED CAR IS LIKELY A REFLECTION OF INCREASED DYNAMIC PHYSIOLOGICAL AROUSAL, AND THE RELATIONSHIP OF THE DUAL ENHANCEMENT OF PRO- AND ANTI-INFLAMMATORY CYTOKINE CHANGES TO HEALTHY IMMUNOLOGIC FUNCTIONING IS DISCUSSED.	2017	
                                                                                                                                                                                                                                                                              
19 2834  42 YOGA'S EFFECT ON INFLAMMATORY BIOMARKERS AND METABOLIC RISK FACTORS IN A HIGH RISK POPULATION - A CONTROLLED TRIAL IN PRIMARY CARE. BACKGROUND: YOGA CAN REDUCE BLOOD PRESSURE AND HAS ALSO BEEN SUGGESTED TO REDUCE INFLAMMATORY BIOMARKERS AND METABOLIC RISK FACTORS FOR CARDIOVASCULAR DISEASES (CVDS). WE AIMED TO ASSESS THE BENEFIT OF TWO YOGA INTERVENTIONS ON INFLAMMATORY BIOMARKERS AND METABOLIC RISK FACTORS IN A HIGH RISK POPULATION IN PRIMARY CARE. METHODS: ADULT PATIENTS FROM A HEALTH CARE CENTER IN SWEDEN, WITH DIAGNOSED HYPERTENSION, WERE INVITED TO UNDERGO A BASELINE CHECK AT THE HEALTH CARE CENTER. BASELINE CHECK INCLUDED STANDARDIZED BLOOD PRESSURE MEASUREMENT, BMI AND WEIGHT CIRCUMFERENCE MEASUREMENTS, BLOOD SAMPLING (HS-CRP, IL-6, FP-GLUCOSE, HBA1C, CHOLESTEROL, TG, LDL AND HDL) AND A QUESTIONNAIRE ON SELF-RATED QUALITY OF LIFE (WHOQOL-BREF). THERE WERE THREE GROUPS: 1) YOGA CLASS WITH YOGA INSTRUCTOR; 2) YOGA AT HOME; AND 3) A CONTROL GROUP. IN TOTAL, 83 PATIENTS WERE INCLUDED AND MATCHED AT THE GROUP LEVEL FOR SYSTOLIC BLOOD PRESSURE. A MAJORITY OF THE PATIENTS (92 %) WERE ON ANTIHYPERTENSIVE MEDICATION, WHICH THEY WERE REQUESTED NOT TO CHANGE DURING THE STUDY. AFTER 12 WEEKS OF INTERVENTION, THE ASSESSMENTS WERE PERFORMED AGAIN. RESULTS: WE RECORDED NO EVIDENCE THAT YOGA ALTERED INFLAMMATORY BIOMARKERS OR METABOLIC RISK FACTORS IN OUR STUDY POPULATION. A TOTAL OF 49 PARTICIPANTS (59 %) MET THE CRITERIA FOR METABOLIC SYNDROME. CONCLUSION: THE YOGA INTERVENTIONS PERFORMED IN OUR STUDY DID NOT AFFECT INFLAMMATORY BIOMARKERS OR METABOLIC RISK FACTORS ASSOCIATED WITH CVD IN THE STUDY POPULATION OF PRIMARY CARE PATIENTS WITH HYPERTENSION. FURTHER RANDOMIZED TRIALS ARE NEEDED TO ELUCIDATE THE EFFECTS OF YOGA ON CVD RISK FACTORS IN THIS PARTICULAR GROUP.

20 1258  35 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
