1  687 194 EFFECT OF AN OFFICE WORKSITE-BASED YOGA PROGRAM ON HEART RATE VARIABILITY: OUTCOMES OF A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: CHRONIC WORK-RELATED STRESS IS AN INDEPENDENT RISK FACTOR FOR CARDIOMETABOLIC DISEASES AND ASSOCIATED MORTALITY, PARTICULARLY WHEN COMPOUNDED BY A SEDENTARY WORK ENVIRONMENT. THE PURPOSE OF THIS STUDY WAS TO DETERMINE IF AN OFFICE WORKSITE-BASED HATHA YOGA PROGRAM COULD IMPROVE PHYSIOLOGICAL STRESS, EVALUATED VIA HEART RATE VARIABILITY (HRV), AND ASSOCIATED HEALTH-RELATED OUTCOMES IN A COHORT OF OFFICE WORKERS. METHODS: THIRTY-SEVEN ADULTS EMPLOYED IN UNIVERSITY-BASED OFFICE POSITIONS WERE RANDOMIZED UPON THE COMPLETION OF BASELINE TESTING TO AN EXPERIMENTAL OR CONTROL GROUP. THE EXPERIMENTAL GROUP COMPLETED A 10-WEEK YOGA PROGRAM PRESCRIBED THREE SESSIONS PER WEEK DURING LUNCH HOUR (50 MIN PER SESSION). AN EXPERIENCED INSTRUCTOR LED THE SESSIONS, WHICH EMPHASIZED ASANAS (POSTURES) AND VINYASA (EXERCISES). THE PRIMARY OUTCOME WAS THE HIGH FREQUENCY (HF) POWER COMPONENT OF HRV. SECONDARY OUTCOMES INCLUDED ADDITIONAL HRV PARAMETERS, MUSCULOSKELETAL FITNESS (I.E. PUSH-UP, SIDE-BRIDGE, AND SIT & REACH TESTS) AND PSYCHOLOGICAL INDICES (I.E. STATE AND TRAIT ANXIETY, QUALITY OF LIFE AND JOB SATISFACTION). RESULTS: ALL MEASURES OF HRV FAILED TO CHANGE IN THE EXPERIMENTAL GROUP VERSUS THE CONTROL GROUP, EXCEPT THAT THE EXPERIMENTAL GROUP SIGNIFICANTLY INCREASED LF:HF (P = 0.04) AND REDUCED PNN50 (P = 0.04) VERSUS CONTROL, CONTRARY TO OUR HYPOTHESES. FLEXIBILITY, EVALUATED VIA SIT & REACH TEST INCREASED IN THE EXPERIMENTAL GROUP VERSUS THE CONTROL GROUP (P < 0.001). NO OTHER ADAPTATIONS WERE NOTED. POST HOC ANALYSIS COMPARING PARTICIPANTS WHO COMPLETED >/=70% OF YOGA SESSIONS (N = 11) TO CONTROL (N = 19) YIELDED THE SAME FINDINGS, EXCEPT THAT THE HIGH ADHERERS ALSO REDUCED STATE ANXIETY (P = 0.02) AND RMSSD (P = 0.05), AND TENDED TO IMPROVE THE PUSH-UP TEST (P = 0.07) VERSUS CONTROL. CONCLUSIONS: A 10-WEEK HATHA YOGA INTERVENTION DELIVERED AT THE OFFICE WORKSITE DURING LUNCH HOUR DID NOT IMPROVE HF POWER OR OTHER HRV PARAMETERS. HOWEVER, IMPROVEMENTS IN FLEXIBILITY, STATE ANXIETY AND MUSCULOSKELETAL FITNESS WERE NOTED WITH HIGH ADHERENCE. FUTURE INVESTIGATIONS SHOULD INCORPORATE STRATEGIES TO PROMOTE ADHERENCE, INVOLVE MORE FREQUENT AND LONGER DURATIONS OF YOGA TRAINING, AND ENROL COHORTS WHO SUFFER FROM HIGHER LEVELS OF WORK-RELATED STRESS.

2  686  95 EFFECT OF AN OFFICE WORKSITE-BASED YOGA PROGRAM ON HEART RATE VARIABILITY: A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: CHRONIC WORK-RELATED STRESS IS A SIGNIFICANT AND INDEPENDENT RISK FACTOR FOR CARDIOVASCULAR AND METABOLIC DISEASES AND ASSOCIATED MORTALITY, PARTICULARLY WHEN COMPOUNDED BY A SEDENTARY WORK ENVIRONMENT. HEART RATE VARIABILITY (HRV) PROVIDES AN ESTIMATE OF PARASYMPATHETIC AND SYMPATHETIC AUTONOMIC CONTROL, AND CAN SERVE AS A MARKER OF PHYSIOLOGICAL STRESS. HATHA YOGA IS A PHYSICALLY DEMANDING PRACTICE THAT CAN HELP TO REDUCE STRESS; HOWEVER, TIME CONSTRAINTS INCURRED BY WORK AND FAMILY LIFE MAY LIMIT PARTICIPATION. THE PURPOSE OF THE PRESENT STUDY IS TO DETERMINE IF A 10-WEEK, WORKSITE-BASED YOGA PROGRAM DELIVERED DURING LUNCH HOUR CAN IMPROVE RESTING HRV AND RELATED PHYSICAL AND PSYCHOLOGICAL PARAMETERS IN SEDENTARY OFFICE WORKERS. METHODS AND DESIGN: THIS IS A PARALLEL-ARM RCT THAT WILL COMPARE THE OUTCOMES OF PARTICIPANTS ASSIGNED TO THE EXPERIMENTAL TREATMENT GROUP (YOGA) TO THOSE ASSIGNED TO A NO-TREATMENT CONTROL GROUP. PARTICIPANTS RANDOMIZED TO THE EXPERIMENTAL CONDITION WILL ENGAGE IN A 10-WEEK YOGA PROGRAM DELIVERED AT THEIR PLACE OF WORK. THE YOGA SESSIONS WILL BE GROUP-BASED, PRESCRIBED THREE TIMES PER WEEK DURING LUNCH HOUR, AND WILL BE LED BY AN EXPERIENCED YOGA INSTRUCTOR. THE PROGRAM WILL INVOLVE TEACHING BEGINNER STUDENTS SAFELY AND PROGRESSIVELY OVER 10 WEEKS A YOGA SEQUENCE THAT INCORPORATES ASANAS (POSES AND POSTURES), VINYASA (EXERCISES), PRANAYAMA (BREATHING CONTROL) AND MEDITATION. THE PRIMARY OUTCOME OF THIS STUDY IS THE HIGH FREQUENCY (HF) SPECTRAL POWER COMPONENT OF HRV (MEASURED IN ABSOLUTE UNITS; I.E. MS2), A MEASURE OF PARASYMPATHETIC AUTONOMIC CONTROL. SECONDARY OUTCOMES INCLUDE ADDITIONAL FREQUENCY AND TIME DOMAINS OF HRV, AND MEASURES OF PHYSICAL FUNCTIONING AND PSYCHOLOGICAL HEALTH STATUS. MEASURES WILL BE COLLECTED PRIOR TO AND FOLLOWING THE INTERVENTION PERIOD, AND AT 6 MONTHS FOLLOW-UP TO DETERMINE THE EFFECT OF INTERVENTION WITHDRAWAL. DISCUSSION: THIS STUDY WILL DETERMINE THE EFFECT OF WORKSITE-BASED YOGA PRACTICE ON HRV AND PHYSICAL AND PSYCHOLOGICAL HEALTH STATUS. THE FINDINGS MAY ASSIST IN IMPLEMENTING PRACTICAL INTERVENTIONS, SUCH AS YOGA, INTO THE WORKPLACE TO MITIGATE STRESS, ENHANCE HEALTH STATUS AND REDUCE THE RISK OF CARDIOVASCULAR AND METABOLIC DISEASES.

3 1062  54 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
4 1063  57 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
5  668  79 EFFECT OF A 16-WEEK BIKRAM YOGA PROGRAM ON HEART RATE VARIABILITY AND ASSOCIATED CARDIOVASCULAR DISEASE RISK FACTORS IN STRESSED AND SEDENTARY ADULTS: A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: CHRONIC ACTIVATION OF THE STRESS-RESPONSE CAN CONTRIBUTE TO CARDIOVASCULAR DISEASE RISK, PARTICULARLY IN SEDENTARY INDIVIDUALS. THIS STUDY INVESTIGATED THE EFFECT OF A BIKRAM YOGA INTERVENTION ON THE HIGH FREQUENCY POWER COMPONENT OF HEART RATE VARIABILITY (HRV) AND ASSOCIATED CARDIOVASCULAR DISEASE (CVD) RISK FACTORS (I.E. ADDITIONAL DOMAINS OF HRV, HEMODYNAMIC, HEMATOLOGIC, ANTHROPOMETRIC AND BODY COMPOSITION OUTCOME MEASURES) IN STRESSED AND SEDENTARY ADULTS. METHODS: ELIGIBLE ADULTS WERE RANDOMIZED TO AN EXPERIMENTAL GROUP (N = 29) OR A NO TREATMENT CONTROL GROUP (N = 34). EXPERIMENTAL GROUP PARTICIPANTS WERE INSTRUCTED TO ATTEND THREE TO FIVE SUPERVISED BIKRAM YOGA CLASSES PER WEEK FOR 16 WEEKS AT LOCAL STUDIOS. OUTCOME MEASURES WERE ASSESSED AT BASELINE (WEEK 0) AND COMPLETION (WEEK 17). RESULTS: SIXTY-THREE ADULTS (37.2 +/- 10.8 YEARS, 79% WOMEN) WERE INCLUDED IN THE INTENTION-TO-TREAT ANALYSIS. THE EXPERIMENTAL GROUP ATTENDED 27 +/- 18 CLASSES. ANALYSES OF COVARIANCE REVEALED NO SIGNIFICANT CHANGE IN THE HIGH-FREQUENCY COMPONENT OF HRV (P = 0.912, PARTIAL ETA (2) = 0.000) OR IN ANY SECONDARY OUTCOME MEASURE BETWEEN GROUPS OVER TIME. HOWEVER, REGRESSION ANALYSES REVEALED THAT HIGHER ATTENDANCE IN THE EXPERIMENTAL GROUP WAS ASSOCIATED WITH SIGNIFICANT REDUCTIONS IN DIASTOLIC BLOOD PRESSURE (P = 0.039; PARTIAL ETA (2) = 0.154), BODY FAT PERCENTAGE (P = 0.001, PARTIAL ETA (2) = 0.379), FAT MASS (P = 0.003, PARTIAL ETA (2) = 0.294) AND BODY MASS INDEX (P = 0.05, PARTIAL ETA (2) = 0.139). CONCLUSIONS: A 16-WEEK BIKRAM YOGA PROGRAM DID NOT INCREASE THE HIGH FREQUENCY POWER COMPONENT OF HRV OR ANY OTHER CVD RISK FACTORS INVESTIGATED. AS REVEALED BY POST HOC ANALYSES, LOW ADHERENCE LIKELY CONTRIBUTED TO THE NULL EFFECTS. FUTURE STUDIES ARE REQUIRED TO ADDRESS BARRIERS TO ADHERENCE TO BETTER ELUCIDATE THE DOSE-RESPONSE EFFECTS OF BIKRAM YOGA PRACTICE AS A MEDIUM TO LOWER STRESS-RELATED CVD RISK.

6 1318  52 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.

7  990  45 EFFECTS OF HATHA YOGA ON STRESS IN MIDDLE-AGED WOMEN. BACKGROUND: STRESS IS CONSIDERED A CRUCIAL TRIGGER FOR PHYSICAL AND MENTAL ILLNESS. STRESS REDUCTION IS A KNOWN LONG-TERM BENEFIT OF REGULAR HATHA YOGA PRACTICE. THE EFFICACY OF A SINGLE-SESSION HATHA YOGA CLASS ON STRESS REDUCTION IS NOT CURRENTLY KNOWN. PURPOSE: THIS STUDY INVESTIGATED THE COMPARATIVE EFFECTIVENESS OF A SINGLE 90-MINUTE HATHA YOGA CLASS AND AN 8-WEEK, 90-MINUTE-CLASS-PER-WEEK COURSE. METHODS: WE USED A QUASIEXPERIMENTAL DESIGN AND RECRUITED 63 FEMALE COMMUNITY RESIDENTS IN NEW TAIPEI CITY AGED 40-60 YEARS. PARTICIPANTS WERE RANDOMLY DIVIDED INTO AN EXPERIMENTAL GROUP (N = 30) AND A CONTROL GROUP (N = 33). THE EXPERIMENTAL GROUP RECEIVED THE 8-WEEK HATHA YOGA COURSE. THE CONTROL GROUP RECEIVED NO INTERVENTION. THE PERCEIVED STRESS SCALE (PSS) AND HEART RATE VARIABILITY (HRV) ASSESSED STRESS REDUCTION EFFECTIVENESS. CHI-SQUARE, INDEPENDENT T TEST, PAIRED T TEST, AND GENERALIZED ESTIMATING EQUATIONS WERE USED FOR DATA ANALYSIS. RESULTS: AFTER A SINGLE 90-MINUTE CLASS OF HATHA YOGA, EXPERIMENTAL GROUP PSS SCORES WERE SIGNIFICANTLY LESS THAN THOSE OF THE CONTROL GROUP (P = .001). ALTHOUGH EXPERIMENTAL GROUP HRV (LOW-FREQUENCY NORM AND HIGH-FREQUENCY NORM) HAD IMPROVED, THESE CHANGES WERE NOT STATISTICALLY SIGNIFICANT (P = .059). PSS SCORES FOR THE SINGLE 90-MINUTE CLASS AND 8-WEEK COURSE DID NOT SIGNIFICANTLY DIFFER (P = .157) AND HRV OF STATISTICS IS SIGNIFICANT (P = .005). GENERALIZED ESTIMATING EQUATIONS ANALYZED CHANGES IN THE EFFECTIVENESS OVER TIME OF STRESS REDUCTION (HRV AND PSS) AFTER THE HATHA YOGA INTERVENTION. RESULTS SHOWED THE POSTINTERVENTION HRV AND PSS OF THE EXPERIMENTAL GROUP DECREASED SIGNIFICANTLY (P < .001) MORE THAN THE CONTROL GROUP. CONCLUSIONS/IMPLICATIONS FOR PRACTICE: OUR FINDINGS SUPPORT THE POSITION THAT REGULAR, LONG-TERM PRACTICE OF HATHA YOGA PROVIDES CLEAR AND SIGNIFICANT HEALTH BENEFITS. PARTICIPATION IN A SINGLE 90-MINUTE HATHA YOGA CLASS CAN SIGNIFICANTLY REDUCE PERCEIVED STRESS. DOING HATHA YOGA REGULARLY CAN REDUCE PERCEIVED STRESS EVEN MORE SIGNIFICANTLY.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
8 1854  63 RANDOMISED CONTROLLED TRIAL OF A 12 WEEK YOGA INTERVENTION ON NEGATIVE AFFECTIVE STATES, CARDIOVASCULAR AND COGNITIVE FUNCTION IN POST-CARDIAC REHABILITATION PATIENTS. BACKGROUND: NEGATIVE AFFECTIVE STATES SUCH AS ANXIETY, DEPRESSION AND STRESS ARE SIGNIFICANT RISK FACTORS FOR CARDIOVASCULAR DISEASE, PARTICULARLY IN CARDIAC AND POST-CARDIAC REHABILITATION POPULATIONS.YOGA IS A BALANCED PRACTICE OF PHYSICAL EXERCISE, BREATHING CONTROL AND MEDITATION THAT CAN REDUCE PSYCHOSOCIAL SYMPTOMS AS WELL AS IMPROVE CARDIOVASCULAR AND COGNITIVE FUNCTION. IT HAS THE POTENTIAL TO POSITIVELY AFFECT MULTIPLE DISEASE PATHWAYS AND MAY PROVE TO BE A PRACTICAL ADJUNCT TO CARDIAC REHABILITATION IN FURTHER REDUCING CARDIAC RISK FACTORS AS WELL AS IMPROVING SELF-EFFICACY AND POST-CARDIAC REHABILITATION ADHERENCE TO HEALTHY LIFESTYLE BEHAVIOURS. METHOD AND DESIGN: THIS IS A PARALLEL ARM, MULTI-CENTRE, RANDOMISED CONTROLLED TRIAL THAT WILL ASSESS THE OUTCOMES OF POST- PHASE 2 CARDIAC REHABILITATION PATIENTS ASSIGNED TO A YOGA INTERVENTION IN COMPARISON TO A NO-TREATMENT WAIT-LIST CONTROL GROUP. PARTICIPANTS RANDOMISED TO THE YOGA GROUP WILL ENGAGE IN A 12 WEEK YOGA PROGRAM COMPRISING OF TWO GROUP BASED SESSIONS AND ONE SELF-ADMINISTERED HOME SESSION EACH WEEK. GROUP BASED SESSIONS WILL BE LED BY AN EXPERIENCED YOGA INSTRUCTOR. THIS WILL INVOLVE TEACHING BEGINNER STUDENTS A HATHA YOGA SEQUENCE THAT INCORPORATES ASANA (POSES AND POSTURES), PRANAYAMA (BREATHING CONTROL) AND MEDITATION. THE PRIMARY OUTCOMES OF THIS STUDY ARE NEGATIVE AFFECTIVE STATES OF ANXIETY, DEPRESSION AND STRESS ASSESSED USING THE DEPRESSION ANXIETY STRESS SCALE. SECONDARY OUTCOMES INCLUDE MEASURES OF QUALITY OF LIFE, AND CARDIOVASCULAR AND COGNITIVE FUNCTION. THE CARDIOVASCULAR OUTCOMES WILL INCLUDE BLOOD PRESSURE, HEART RATE, HEART RATE VARIABILITY, PULSE WAVE VELOCITY, CAROTID INTIMA MEDIA THICKNESS MEASUREMENTS, LIPID/GLUCOSE PROFILES AND C-REACTIVE PROTEIN ASSAYS. ASSESSMENTS WILL BE CONDUCTED PRIOR TO (WEEK 0), MID-WAY THROUGH (WEEK 6) AND FOLLOWING THE INTERVENTION PERIOD (WEEK 12) AS WELL AS AT A FOUR WEEK FOLLOW-UP (WEEK 16). DISCUSSION: THIS STUDY WILL DETERMINE THE EFFECT OF YOGA PRACTICE ON NEGATIVE AFFECTIVE STATES, CARDIOVASCULAR AND COGNITIVE FUNCTION IN POST-PHASE 2 CARDIAC REHABILITATION PATIENTS. THE FINDINGS MAY PROVIDE EVIDENCE TO INCORPORATE YOGA INTO STANDARDISED CARDIAC REHABILITATION PROGRAMS AS A PRACTICAL ADJUNCT TO IMPROVE THE MANAGEMENT OF PSYCHOSOCIAL SYMPTOMS ASSOCIATED WITH CARDIOVASCULAR EVENTS IN ADDITION TO IMPROVING PATIENTS' COGNITIVE AND CARDIOVASCULAR FUNCTIONS.

9 1902  56 RESTORATIVE YOGA IN ADULTS WITH METABOLIC SYNDROME: A RANDOMIZED, CONTROLLED PILOT TRIAL. BACKGROUND: METABOLIC SYNDROME INCREASES THE RISK OF DIABETES AND CARDIOVASCULAR DISEASE. YOGA IMPROVES SOME METABOLIC PARAMETERS, BUT IT HAS NOT BEEN STUDIED IN PERSONS WITH METABOLIC SYNDROME. WE CONDUCTED A RANDOMIZED CONTROLLED PILOT TRIAL TO DETERMINE WHETHER A RESTORATIVE YOGA INTERVENTION WAS FEASIBLE AND ACCEPTABLE IN UNDERACTIVE, OVERWEIGHT ADULTS WITH METABOLIC SYNDROME. METHODS: TWENTY SIX UNDERACTIVE, OVERWEIGHT ADULT MEN AND WOMEN WITH METABOLIC SYNDROME WERE RANDOMIZED TO ATTEND 15 YOGA SESSIONS OF 90 MINUTES EACH OVER 10 WEEKS OR TO A WAIT-LIST CONTROL GROUP. FEASIBILITY WAS MEASURED BY RECRUITMENT RATES, SUBJECT RETENTION, AND ADHERENCE. ACCEPTABILITY WAS ASSESSED BY INTERVIEW AND QUESTIONNAIRES. CHANGES IN METABOLIC OUTCOMES AND QUESTIONNAIRE MEASURES FROM BASELINE TO WEEK 10 WERE CALCULATED. RESULTS: A TOTAL OF 280 PEOPLE WERE SCREENED BY PHONE, AND 93 WITH HIGH LIKELIHOOD OF METABOLIC SYNDROME WERE INVITED TO A SCREENING VISIT. OF THE 68 WHO ATTENDED SCREENING VISITS, 26 (38%) WERE RANDOMIZED, AND 24 (92%) COMPLETED THE TRIAL. ATTENDANCE AT YOGA CLASSES AND ADHERENCE TO HOME PRACTICE EXCEEDED OUR GOALS. IN THE YOGA GROUP, ALL PARTICIPANTS GAVE THE STUDY THE HIGHEST POSSIBLE SATISFACTION RATING, AND THE MAJORITY (87%) FELT THAT THE YOGA POSES WERE EASY TO PERFORM. THERE WAS TREND TO REDUCED BLOOD PRESSURE (P = 0.07), A SIGNIFICANT INCREASE IN ENERGY LEVEL (P < 0.009), AND TRENDS TO IMPROVEMENT IN WELL-BEING (P < 0.12) AND STRESS (P < 0.22) IN THE YOGA VERSUS CONTROL GROUP. CONCLUSIONS: RESTORATIVE YOGA WAS A FEASIBLE AND ACCEPTABLE INTERVENTION IN OVERWEIGHT ADULTS WITH METABOLIC SYNDROME. THE EFFICACY OF YOGA FOR IMPROVING METABOLIC PARAMETERS IN THIS POPULATION SHOULD BE EXPLORED IN A LARGER RANDOMIZED CONTROLLED TRIAL.	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
10  159  45 A RANDOMISED COMPARATIVE TRIAL OF YOGA AND RELAXATION TO REDUCE STRESS AND ANXIETY. OBJECTIVE: TO COMPARE YOGA AND RELAXATION AS TREATMENT MODALITIES AT 10 AND 16 WEEKS FROM STUDY BASELINE TO DETERMINE IF EITHER OF MODALITY REDUCES SUBJECT STRESS, ANXIETY, BLOOD PRESSURE AND IMPROVE QUALITY OF LIFE. DESIGN: A RANDOMISED COMPARATIVE TRIAL WAS UNDERTAKEN COMPARING YOGA WITH RELAXATION. PARTICIPANTS: ONE HUNDRED AND THIRTY-ONE SUBJECTS WITH MILD TO MODERATE LEVELS OF STRESS WERE RECRUITED FROM THE COMMUNITY IN SOUTH AUSTRALIA. INTERVENTIONS: TEN WEEKLY 1- H SESSIONS OF RELAXATION OR HATHA YOGA. MAIN OUTCOME MEASURES: CHANGES IN THE STATE TRAIT PERSONALITY INVENTORY SUB-SCALE ANXIETY, GENERAL HEALTH QUESTIONNAIRE AND THE SHORT FORM-36. RESULTS: FOLLOWING THE 10 WEEK INTERVENTION STRESS, ANXIETY AND QUALITY OF LIFE SCORES IMPROVED OVER TIME. YOGA WAS FOUND TO BE AS EFFECTIVE AS RELAXATION IN REDUCING STRESS, ANXIETY AND IMPROVING HEALTH STATUS ON SEVEN DOMAINS OF THE SF-36. YOGA WAS MORE EFFECTIVE THAN RELAXATION IN IMPROVING MENTAL HEALTH. AT THE END OF THE 6 WEEK FOLLOW-UP PERIOD THERE WERE NO DIFFERENCES BETWEEN GROUPS IN LEVELS OF STRESS, ANXIETY AND ON FIVE DOMAINS OF THE SF-36. VITALITY, SOCIAL FUNCTION AND MENTAL HEALTH SCORES ON THE SF-36 WERE HIGHER IN THE RELAXATION GROUP DURING THE FOLLOW-UP PERIOD. CONCLUSION: YOGA APPEARS TO PROVIDE A COMPARABLE IMPROVEMENT IN STRESS, ANXIETY AND HEALTH STATUS COMPARED TO RELAXATION.	2007	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
11 1258  44 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
12   60  46 A COMPARISON OF THE EFFECTS OF HATHA YOGA AND RESISTANCE EXERCISE ON MENTAL HEALTH AND WELL-BEING IN SEDENTARY ADULTS: A PILOT STUDY. OBJECTIVES: PHYSICAL ACTIVITY HAS A POSITIVE EFFECT ON PEOPLE'S MENTAL HEALTH AND WELL-BEING. THE AIM OF THIS STUDY WAS TO COMPARE THE EFFECTS OF HATHA YOGA AND RESISTANCE EXERCISES ON MENTAL HEALTH AND WELL-BEING IN SEDENTARY ADULTS. DESIGN: RANDOMIZED CONTROLLED STUDY. METHODS: FIFTY-ONE PARTICIPANTS AGED MEAN (SD) 25.6 (5.7) YEARS WERE RANDOMLY DIVIDED INTO THREE GROUPS: HATHA YOGA GROUP, RESISTANCE EXERCISE GROUP AND CONTROL GROUP. THE HATHA YOGA GROUP AND RESISTANCE EXERCISE GROUP PARTICIPATED IN SESSIONS THREE DAYS PER WEEK FOR 7 WEEKS AND THE CONTROL GROUP DID NOT PARTICIPATE IN ANY SESSIONS. ALL THE SUBJECTS WERE EVALUATED THROUGH THE ROSENBERG SELF-ESTEEM SCALE, BECK DEPRESSION INVENTORY, BODY CATHEXIS SCALE, NOTTINGHAM HEALTH PROFILE AND VISUAL ANALOG SCALE FOR FATIGUE PRE-AND POST-SESSION. RESULTS: SIGNIFICANT IMPROVEMENTS WERE FOUND IN TERMS OF ALL OUTCOME MEASURES IN THE HATHA YOGA GROUP AND THE RESISTANCE EXERCISE GROUP. NO IMPROVEMENTS WERE FOUND IN THE CONTROL GROUP. HATHA YOGA MORE IMPROVED THE DIMENSIONS FATIGUE, SELF-ESTEEM, AND QUALITY OF LIFE, WHILST RESISTANCE EXERCISE TRAINING MORE IMPROVED BODY IMAGE. HATHA YOGA AND RESISTANCE EXERCISE DECREASED DEPRESSION SYMPTOMS AT A SIMILAR LEVEL. CONCLUSION: THE RESULTS INDICATED THAT HATHA YOGA AND RESISTANCE EXERCISE HAD POSITIVE EFFECTS ON MENTAL HEALTH AND WELL-BEING IN SEDENTARY ADULTS. HATHA YOGA AND RESISTANCE EXERCISE MAY AFFECT DIFFERENT ASPECTS OF MENTAL HEALTH AND WELL-BEING.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
13 2667  42 YOGA IN HEART FAILURE PATIENTS: A PILOT STUDY. BACKGROUND: COMPLEMENTARY THERAPIES SUCH AS YOGA PRACTICE HAVE BECOME COMMONPLACE, YET THE SAFETY, PHYSICAL, AND PSYCHOLOGICAL EFFECTS ON PATIENTS WITH HEART FAILURE (HF) ARE UNKNOWN. THE PURPOSE OF THIS STUDY WAS TO DETERMINE WHETHER AN 8-WEEK YOGA PROGRAM WAS SAFE AND WOULD POSITIVELY INFLUENCE PHYSICAL AND PSYCHOLOGICAL FUNCTION IN HF PATIENTS. METHODS AND RESULTS: STABLE HF PATIENTS WERE RECRUITED (N = 15) AND COMPLETED (N = 12) 8 WEEKS OF YOGA CLASSES. DATA COLLECTED WERE: SAFETY (CARDIAC AND ORTHOPEDIC ADVERSE EVENTS); PHYSICAL FUNCTION (STRENGTH, BALANCE, ENDURANCE, FLEXIBILITY); AND PSYCHOLOGICAL FUNCTION (QUALITY OF LIFE [QOL], DEPRESSION SCORES, MINDFULNESS) BEFORE AND AFTER 8 WEEKS OF YOGA CLASSES. RESULTS: MEAN AGE WAS 52.4 + OR - 11.6 WITH THREE-FOURTHS (N = 9) BEING MALE AND CAUCASIAN. NO PARTICIPANT HAD ANY ADVERSE EVENTS. ENDURANCE (P < .02) AND STRENGTH (UPPER P = .04 AND LOWER BODY P = .01) SIGNIFICANTLY IMPROVED. BALANCE IMPROVED BY 13.6 SECONDS (26.9 + OR - 19.7 TO 40.0 + OR - 18.5; P = .05). SYMPTOM STABILITY, A SUBSCALE OF QOL, IMPROVED SIGNIFICANTLY (P = .02). ALTHOUGH NO SUBJECT WAS DEPRESSED, OVERALL MOOD WAS IMPROVED. SUBJECTS SUBJECTIVELY REPORTED IMPROVEMENTS IN OVERALL WELL-BEING. CONCLUSIONS: YOGA PRACTICE WAS SAFE, WITH PARTICIPANTS EXPERIENCING IMPROVED PHYSICAL FUNCTION AND SYMPTOM STABILITY. LARGER STUDIES ARE WARRANTED TO PROVIDE MORE NONPHARMACOLOGICAL OPTIONS FOR IMPROVED OUTCOMES IN PATIENTS WITH HF.	2010	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
14  428  44 CAN YOGA HAVE ANY EFFECT ON SHOULDER AND ARM PAIN AND QUALITY OF LIFE IN PATIENTS WITH BREAST CANCER? A RANDOMIZED, CONTROLLED, SINGLE-BLIND TRIAL. OBJECTIVE: TO EXAMINE THE EFFECTS OF YOGA ON SHOULDER AND ARM PAIN, QUALITY OF LIFE (QOL), DEPRESSION, AND PHYSICAL PERFORMANCE IN PATIENTS WITH BREAST CANCER. METHODS: THIS PROSPECTIVE, RANDOMIZED STUDY INCLUDED 42 PATIENTS. THE PATIENTS IN GROUP 1 UNDERWENT A 10-WEEK HATHA YOGA EXERCISE PROGRAM. THE PATIENTS IN GROUP 2 WERE INCLUDED IN A 10-WEEK FOLLOW-UP PROGRAM. OUR PRIMARY ENDPOINT WAS ARM AND SHOULDER PAIN INTENSITY. RESULTS: THE GROUP RECEIVING YOGA SHOWED A SIGNIFICANT IMPROVEMENT IN THEIR PAIN SEVERITY FROM BASELINE TO POST-TREATMENT, AND THESE BENEFITS WERE MAINTAINED AT 2.5 MONTHS POST-TREATMENT. WHEN COMPARED TO THE CONTROL GROUP, THERE WERE NO STATISTICALLY SIGNIFICANT DIFFERENCES BETWEEN THE 2 GROUPS WITH RESPECT TO THE PARAMETERS ASSESSED AT THE END OF WEEK 10. CONCLUSION: YOGA WAS AN EFFECTIVE AND SAFE EXERCISE FOR ALLEVIATING SHOULDER AND ARM PAIN, WHICH IS A COMPLICATION WITH A HIGH PREVALENCE IN PATIENTS WITH BREAST CANCER.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
15 2222  64 THE IMPACT OF MODIFIED HATHA YOGA ON CHRONIC LOW BACK PAIN: A PILOT STUDY. PURPOSE: THE PURPOSE OF THIS RANDOMIZED PILOT STUDY WAS TO EVALUATE A POSSIBLE DESIGN FOR A 6-WEEK MODIFIED HATHA YOGA PROTOCOL TO STUDY THE EFFECTS ON PARTICIPANTS WITH CHRONIC LOW BACK PAIN. PARTICIPANTS: TWENTY-TWO PARTICIPANTS (M = 4; F = 17), BETWEEN THE AGES OF 30 AND 65, WITH CHRONIC LOW BACK PAIN (CLBP) WERE RANDOMIZED TO EITHER AN IMMEDIATE YOGA BASED INTERVENTION, OR TO A CONTROL GROUP WITH NO TREATMENT DURING THE OBSERVATION PERIOD BUT RECEIVED LATER YOGA TRAINING. METHODS: A SPECIFIC CLBP YOGA PROTOCOL DESIGNED AND MODIFIED FOR THIS POPULATION BY A CERTIFIED YOGA INSTRUCTOR WAS ADMINISTERED FOR ONE HOUR, TWICE A WEEK FOR 6 WEEKS. PRIMARY FUNCTIONAL OUTCOME MEASURES INCLUDED THE FORWARD REACH (FR) AND SIT AND REACH (SR) TESTS. ALL PARTICIPANTS COMPLETED OSWESTRY DISABILITY INDEX (ODI) AND BECK DEPRESSION INVENTORY (BDI) QUESTIONNAIRES. GUIDING QUESTIONS WERE USED FOR QUALITATIVE DATA ANALYSIS TO ASCERTAIN HOW YOGA PARTICIPANTS PERCEIVED THE INSTRUCTOR, GROUP DYNAMICS, AND THE IMPACT OF YOGA ON THEIR LIFE. ANALYSIS: TO ACCOUNT FOR DROP OUTS, THE DATA WERE DIVIDED INTO BETTER OR NOT CATEGORIES, AND ANALYZED USING CHI-SQUARE TO EXAMINE DIFFERENCES BETWEEN THE GROUPS. QUALITATIVE DATA WERE ANALYZED THROUGH FREQUENCY OF POSITIVE RESPONSES. RESULTS: POTENTIALLY IMPORTANT TRENDS IN THE FUNCTIONAL MEASUREMENT SCORES SHOWED IMPROVED BALANCE AND FLEXIBILITY AND DECREASED DISABILITY AND DEPRESSION FOR THE YOGA GROUP BUT THIS PILOT WAS NOT POWERED TO REACH STATISTICAL SIGNIFICANCE. SIGNIFICANT LIMITATIONS INCLUDED A HIGH DROPOUT RATE IN THE CONTROL GROUP AND LARGE BASELINE DIFFERENCES IN THE SECONDARY MEASURES. IN ADDITION, ANALYSIS OF THE QUALITATIVE DATA REVEALED THE FOLLOWING FREQUENCY OF RESPONSES (1) GROUP INTERVENTION MOTIVATED THE PARTICIPANTS AND (2) YOGA FOSTERED RELAXATION AND NEW AWARENESS/LEARNING. CONCLUSION: A MODIFIED YOGA-BASED INTERVENTION MAY BENEFIT INDIVIDUALS WITH CLB, BUT A LARGER STUDY IS NECESSARY TO PROVIDE DEFINITIVE EVIDENCE. ALSO, THE IMPACT ON DEPRESSION AND DISABILITY COULD BE CONSIDERED AS IMPORTANT OUTCOMES FOR FURTHER STUDY. ADDITIONAL FUNCTIONAL OUTCOME MEASURES SHOULD BE EXPLORED. THIS PILOT STUDY SUPPORTS THE NEED FOR MORE RESEARCH INVESTIGATING THE EFFECT OF YOGA FOR THIS POPULATION.	2004	
                                                                                                                                                                                                                                                                                                       
16 1076  42 EFFECTS OF YOGA ON PHYSIOLOGICAL INDICES, ANXIETY AND SOCIAL FUNCTIONING IN MULTIPLE SCLEROSIS PATIENTS: A RANDOMIZED TRIAL. INTRODUCTION: MULTIPLE SCLEROSIS (MS) AS A CHRONIC DISEASE COULD AFFECT PATIENTS' VARIOUS DOMAINS OF LIFE. AIM: THIS STUDY WAS CONDUCTED TO STUDY THE EFFECT OF YOGA ON THE PHYSIOLOGICAL INDICES, ANXIETY AND SOCIAL FUNCTIONING OF PATIENTS WITH MS IN SOUTHWEST, IRAN. MATERIALS AND METHODS: IN THIS CLINICAL TRIAL STUDY, 60 MS PATIENTS WERE ENROLLED ACCORDING TO INCLUSION CRITERIA AND RANDOMLY ASSIGNED TO TWO GROUPS OF 30 EACH. PRIOR TO AND AFTER INTERVENTION, THE PATIENTS' VITAL SIGNS WERE MEASURED. FOR CASE GROUP YOGA EXERCISES WERE PERFORMED THREE SESSIONS A WEEK FOR 12 WEEKS WHILE CONTROL GROUP PERFORMED NO EXERCISE. THE DATA WERE GATHERED BY QUESTIONNAIRE AND ANALYSED BY DESCRIPTIVE AND ANALYTICAL STATISTICS IN SPSS. RESULTS: PRIOR TO INTERVENTION, THERE WAS NO SIGNIFICANT DIFFERENCE IN FATIGUE SEVERITY AND PAIN BETWEEN THE TWO GROUPS BUT THE MEAN FATIGUE SEVERITY AND PAIN IN CASE GROUP DECREASED COMPARED TO THE CONTROL GROUP AFTER THE INTERVENTION. PRIOR TO INTERVENTION, THERE WAS NO SIGNIFICANT DIFFERENCE IN MEAN PHYSIOLOGICAL INDICES BETWEEN THE TWO GROUPS BUT THE MEAN PHYSIOLOGICAL INDICES IN CASE GROUP DECREASED SIGNIFICANTLY AFTER THE INTERVENTION (P<0.05). CONCLUSION: YOGA IS LIKELY TO INCREASE SELF-EFFICACY OF MS PATIENTS THROUGH ENHANCING PHYSICAL ACTIVITY, INCREASING THE STRENGTH OF LOWER LIMBS AND BALANCE, AND DECREASING FATIGUE AND PAIN, AND FINALLY TO PROMOTE SOCIAL FUNCTIONING AND TO RELIEVE STRESS AND ANXIETY IN THESE PATIENTS.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
17  243  46 A YOGA & EXERCISE RANDOMIZED CONTROLLED TRIAL FOR VASOMOTOR SYMPTOMS: EFFECTS ON HEART RATE VARIABILITY. OBJECTIVES: HEART RATE VARIABILITY (HRV) REFLECTS THE INTEGRATION OF THE PARASYMPATHETIC NERVOUS SYSTEM WITH THE REST OF THE BODY. STUDIES ON THE EFFECTS OF YOGA AND EXERCISE ON HRV HAVE BEEN MIXED BUT SUGGEST THAT EXERCISE INCREASES HRV. WE CONDUCTED A SECONDARY ANALYSIS OF THE EFFECT OF YOGA AND EXERCISE ON HRV BASED ON A RANDOMIZED CLINICAL TRIAL OF TREATMENTS FOR VASOMOTOR SYMPTOMS IN PERI/POST-MENOPAUSAL WOMEN. DESIGN: RANDOMIZED CLINICAL TRIAL OF BEHAVIORAL INTERVENTIONS IN WOMEN WITH VASOMOTOR SYMPTOMS (N=335), 40-62 YEARS OLD FROM THREE CLINICAL STUDY SITES. INTERVENTIONS: 12-WEEKS OF A YOGA PROGRAM, DESIGNED SPECIFICALLY FOR MID-LIFE WOMEN, OR A SUPERVISED AEROBIC EXERCISE-TRAINING PROGRAM WITH SPECIFIC INTENSITY AND ENERGY EXPENDITURE GOALS, COMPARED TO A USUAL ACTIVITY GROUP. MAIN OUTCOME MEASURES: TIME AND FREQUENCY DOMAIN HRV MEASURED AT BASELINE AND AT 12 WEEKS FOR 15MIN USING HOLTER MONITORS. RESULTS: WOMEN HAD A MEDIAN OF 7.6 VASOMOTOR SYMPTOMS PER 24H. TIME AND FREQUENCY DOMAIN HRV MEASURES DID NOT CHANGE SIGNIFICANTLY IN EITHER OF THE INTERVENTION GROUPS COMPARED TO THE CHANGE IN THE USUAL ACTIVITY GROUP. HRV RESULTS DID NOT DIFFER WHEN THE ANALYSES WERE RESTRICTED TO POST-MENOPAUSAL WOMEN. CONCLUSIONS: ALTHOUGH YOGA AND EXERCISE HAVE BEEN SHOWN TO INCREASE PARASYMPATHETIC-MEDIATED HRV IN OTHER POPULATIONS, NEITHER INTERVENTION INCREASED HRV IN MIDDLE-AGED WOMEN WITH VASOMOTOR SYMPTOMS. MIXED RESULTS IN PREVIOUS RESEARCH MAY BE DUE TO SAMPLE DIFFERENCES. YOGA AND EXERCISE LIKELY IMPROVE SHORT-TERM HEALTH IN MIDDLE-AGED WOMEN THROUGH MECHANISMS OTHER THAN HRV.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
18 2680  59 YOGA IN SCHOOL SPORTS IMPROVES FUNCTIONING OF AUTONOMIC NERVOUS SYSTEM IN YOUNG ADULTS: A NON-RANDOMIZED CONTROLLED PILOT STUDY. BACKGROUND: YOGA IN SCHOOL IS A BENEFICIAL TOOL TO PROMOTE THE GOOD HEALTH AND WELL-BEING OF STUDENTS BY CHANGING THE WAY THEY REACT TO STRESS. THE POSITIVE EFFECTS OF YOGA-TAUGHT IN SCHOOLS-ON CHILDREN, YOUTH AND YOUNG ADULTS HAVE BEEN DEMONSTRATED IN FORMER STUDIES USING MOSTLY SUBJECTIVE PSYCHOMETRIC DATA. AIM: THE PRESENT TRIAL AIMS TO EVALUATE THE POTENTIAL EFFECTS OF YOGA ON AUTONOMIC REGULATION IN YOUNG ADULTS BY ANALYZING HEART RATE VARIABILITY (HRV). METHODS: THIS STUDY IS A NON-RANDOMIZED, EXPLORATIVE, TWO-ARM-PILOT STUDY WITH AN ACTIVE CONTROL GROUP. FOURTEEN HEALTHY YOUNG ADULTS TOOK PART IN A 10-WEEK YOGA PROGRAM (90 MIN ONCE A WEEK) IN SCHOOL AND WERE COMPARED TO A CONTROL GROUP OF 11 STUDENTS WHO PARTICIPATED IN CONVENTIONAL SCHOOL SPORTS (90 MIN ONCE A WEEK OVER 10 WEEKS). 24-HOUR ELECTROCARDIOGRAMS (ECGS) WERE RECORDED AT BASELINE AND FOLLOWING THE 10-WEEK INTERVENTION. FROM 20-MINUTE OF NOCTURNAL SLEEP PHASES, HRV PARAMETERS WERE CALCULATED FROM LINEAR (TIME AND FREQUENCY DOMAIN) AND NONLINEAR DYNAMICS (SUCH AS SYMBOLIC DYNAMICS AND POINCARE PLOT ANALYSIS). ANALYSES OF VARIANCE (ANOVA) FOLLOWED BY T-TESTS AS POST-HOC TESTS ESTIMATING BOTH STATISTICAL SIGNIFICANCE AND EFFECT SIZE WERE USED TO COMPARE PRE-POST-INTERVENTION FOR THE TWO GROUPS. RESULTS: THE STATISTICAL ANALYSIS OF THE INTERACTION EFFECTS DID NOT REVEAL A SIGNIFICANT GROUP AND TIME INTERACTION FOR THE INDIVIDUAL NOCTURNAL HRV INDICES. ALMOST ALL INDICES REVEALED MEDIUM AND LARGE EFFECTS REGARDING THE TIME MAIN EFFECTS. THE CHANGES IN THE HRV INDICES FOLLOWING THE INTERVENTION WERE MORE DRAMATIC FOR THE YOGA GROUP THAN FOR THE CONTROL GROUP WHICH IS REFLECTED IN PREDOMINANTLY HIGHER SIGNIFICANCES AND STRONGER EFFECT SIZES IN THE YOGA GROUP. CONCLUSION: IN THIS EXPLORATIVE PILOT TRIAL, AN INCREASE OF HRV (MORE PARASYMPATHETIC DOMINANCE AND OVERALL HIGHER HRV) AFTER TEN WEEKS OF YOGA IN SCHOOL IN COMPARISON TO REGULAR SCHOOL SPORTS WAS DEMONSTRATED, SHOWING AN IMPROVED SELF-REGULATION OF THE AUTONOMIC NERVOUS SYSTEM.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
19 1402  53 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
20 1869  45 RANDOMIZED, CONTROLLED, SIX-MONTH TRIAL OF YOGA IN HEALTHY SENIORS: EFFECTS ON COGNITION AND QUALITY OF LIFE. CONTEXT: THERE ARE POTENTIAL BENEFITS OF MIND-BODY TECHNIQUES ON COGNITIVE FUNCTION BECAUSE THE TECHNIQUES INVOLVE AN ACTIVE ATTENTIONAL OR MINDFULNESS COMPONENT, BUT THIS HAS NOT BEEN FULLY EXPLORED. OBJECTIVE: TO DETERMINE THE EFFECT OF YOGA ON COGNITIVE FUNCTION, FATIGUE, MOOD, AND QUALITY OF LIFE IN SENIORS. DESIGN: RANDOMIZED, CONTROLLED TRIAL COMPARING YOGA, EXERCISE, AND WAIT-LIST CONTROL GROUPS. PARTICIPANTS: ONE HUNDRED THIRTY-FIVE GENERALLY HEALTHY MEN AND WOMEN AGED 65-85 YEARS. INTERVENTION: PARTICIPANTS WERE RANDOMIZED TO 6 MONTHS OF HATHA YOGA CLASS, WALKING EXERCISE CLASS, OR WAIT-LIST CONTROL. SUBJECTS ASSIGNED TO CLASSES ALSO WERE ASKED TO PRACTICE AT HOME. MAIN OUTCOME MEASURES: OUTCOME ASSESSMENTS PERFORMED AT BASELINE AND AFTER THE 6-MONTH PERIOD INCLUDED A BATTERY OF COGNITIVE MEASURES FOCUSED ON ATTENTION AND ALERTNESS, THE PRIMARY OUTCOME MEASURES BEING PERFORMANCE ON THE STROOP TEST AND A QUANTITATIVE ELECTROENCEPHALOGRAM (EEG) MEASURE OF ALERTNESS; SF-36 HEALTH-RELATED QUALITY OF LIFE; PROFILE OF MOOD STATES; MULTI-DIMENSIONAL FATIGUE INVENTORY; AND PHYSICAL MEASURES RELATED TO THE INTERVENTIONS. RESULTS: ONE HUNDRED THIRTY-FIVE SUBJECTS WERE RECRUITED AND RANDOMIZED. SEVENTEEN SUBJECTS DID NOT FINISH THE 6-MONTH INTERVENTION. THERE WERE NO EFFECTS FROM EITHER OF THE ACTIVE INTERVENTIONS ON ANY OF THE COGNITIVE AND ALERTNESS OUTCOME MEASURES. THE YOGA INTERVENTION PRODUCED IMPROVEMENTS IN PHYSICAL MEASURES (EG, TIMED 1-LEGGED STANDING, FORWARD FLEXIBILITY) AS WELL AS A NUMBER OF QUALITY-OF-LIFE MEASURES RELATED TO SENSE OF WELL-BEING AND ENERGY AND FATIGUE COMPARED TO CONTROLS. CONCLUSIONS: THERE WERE NO RELATIVE IMPROVEMENTS OF COGNITIVE FUNCTION AMONG HEALTHY SENIORS IN THE YOGA OR EXERCISE GROUP COMPARED TO THE WAIT-LIST CONTROL GROUP. THOSE IN THE YOGA GROUP SHOWED SIGNIFICANT IMPROVEMENT IN QUALITY-OF-LIFE AND PHYSICAL MEASURES COMPARED TO EXERCISE AND WAIT-LIST CONTROL GROUPS.	2006
