1 2149 61 THE EFFECTS OF POWER AND STRETCH YOGA ON AFFECT AND SALIVARY CORTISOL IN WOMEN. YOGA PRACTICE IS KNOWN TO IMPROVE WELL-BEING AND DECREASE STRESS. HOWEVER, ACUTE YOGA IS UNDERSTUDIED. THIS STUDY INVESTIGATED THE EFFECTS OF TWO DIFFERENT TYPES OF YOGA ON AFFECT AND SALIVARY CORTISOL LEVELS IN COLLEGE WOMEN. THIRTY-THREE WOMEN AGED 18-30 YEARS EACH COMPLETED 1-HOUR SESSIONS OF POWER YOGA AND STRETCH YOGA. MEASURES OF AFFECT AND SALIVARY CORTISOL WERE ASSESSED BEFORE, DURING, AND AFTER EACH SESSION. PARTICIPANTS PERCEIVED POWER YOGA TO BE MORE PLEASURABLE AND ENERGIZING. SALIVARY CORTISOL SIGNIFICANTLY DECREASED AFTER BOTH YOGA SESSIONS. THUS, EVEN ONE SESSION OF YOGA MAY BE EFFECTIVE IN IMPROVING AFFECT AND DECREASING STRESS IN COLLEGE WOMEN.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
2 2778 20 YOGA STRETCHING FOR IMPROVING SALIVARY IMMUNE FUNCTION AND MENTAL STRESS IN MIDDLE-AGED AND OLDER ADULTS. PROTECTION AGAINST AGE-RELATED IMMUNE SUPPRESSION IS IMPORTANT IN ELDERLY INDIVIDUALS. THIS STUDY DETERMINED THE EFFECT OF YOGA ON MUCOSAL IMMUNE FUNCTION AND MENTAL STRESS. SALIVA SAMPLES WERE COLLECTED FROM 23 ADULT WOMEN (AGE: 60.4 +/- 10.4 YEARS) BEFORE AND AFTER 90 MINUTES OF YOGA STRETCHING OR REST TO MEASURE SECRETORY IMMUNOGLOBULIN A (SIGA), CORTISOL, AND TESTOSTERONE. THE SIGA CONCENTRATION AND SECRETION RATE WERE SIGNIFICANTLY HIGHER AFTER YOGA THAN BEFORE (P < .05). THE CORTISOL CONCENTRATION AND SECRETION RATE WERE LOWER AND TESTOSTERONE SECRETION RATE HIGHER AFTER YOGA (P < .05). YOGA STRETCHING CAN REDUCE STRESS AND ENHANCE MUCOSAL IMMUNE FUNCTION IN ELDERLY WOMEN.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
3  720 24 EFFECT OF IYENGAR YOGA PRACTICE ON FATIGUE AND DIURNAL SALIVARY CORTISOL CONCENTRATION IN BREAST CANCER SURVIVORS. PURPOSE: TO EXAMINE THE EFFECT OF REGULAR IYENGAR YOGA PRACTICE ON MEASURES OF SELF-PERCEIVED PSYCHOSOCIAL FUNCTION AND DIURNAL SALIVARY CORTISOL SECRETION IN STAGE II-IV BREAST CANCER SURVIVORS (N = 18). DATA SOURCES: WOMEN WERE RANDOMLY ASSIGNED TO ATTEND YOGA PRACTICE FOR 90 MIN TWICE WEEKLY FOR 8 WEEKS (N = 9) OR TO A WAIT-LISTED, NONINTERVENTIONAL CONTROL GROUP (N = 9). TRADITIONAL IYENGAR YOGA ROUTINES THAT PROGRESSIVELY INCREASED IN DIFFICULTY AS PARTICIPANTS GAINED STRENGTH AND FLEXIBILITY WERE USED. AT BASELINE AND AFTER THE 8-WEEK STUDY PERIOD, WOMEN COMPLETED SELF-REPORT INSTRUMENTS TO DOCUMENT VARIOUS ASPECTS OF PSYCHOSOCIAL AND PHYSICAL FUNCTIONING, AND COLLECTED SALIVARY SAMPLES FOR CORTISOL ANALYSIS FOUR TIMES DURING THE DAY FOR TWO CONSECUTIVE DAYS. CONCLUSIONS: THE YOGA GROUP HAD LOWER MORNING AND 5 P.M. SALIVARY CORTISOL AND IMPROVED EMOTIONAL WELL-BEING AND FATIGUE SCORES. IMPLICATIONS FOR PRACTICE: BREAST CANCER SURVIVORS ARE AT RISK FOR CHRONIC PSYCHOSOCIAL DISTRESS THAT MAY ALTER ACTIVITY OF THE HYPOTHALAMIC-PITUITARY-ADRENAL AXIS, RESULTING IN ABERRANT REGULATION OF CORTISOL SECRETION AND INCREASED RISK OF IMMUNE DYSFUNCTION AND CANCER PROGRESSION. REGULAR YOGA PRACTICE MAY BE A LOW-RISK, COST-EFFECTIVE WAY TO IMPROVE PSYCHOSOCIAL FUNCTIONING, FATIGUE, AND REGULATION OF CORTISOL SECRETION IN BREAST CANCER SURVIVORS. THESE FINDINGS REQUIRE VALIDATION WITH A LARGER RANDOMIZED STUDY.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
4 1562 22 LONGITUDINAL AND IMMEDIATE EFFECT OF KUNDALINI YOGA ON SALIVARY LEVELS OF CORTISOL AND ACTIVITY OF ALPHA-AMYLASE AND ITS EFFECT ON PERCEIVED STRESS. CONTEXT: STRESS IS DEFINED AS AN ALTERATION OF AN ORGANISM'S BALANCE IN RESPONSE TO A DEMAND PERCEIVED FROM THE ENVIRONMENT. DIVERSE METHODS EXIST TO EVALUATE PHYSIOLOGICAL RESPONSE. A NONINVASIVE METHOD IS SALIVARY MEASUREMENT OF CORTISOL AND ALPHA-AMYLASE. A GROWING BODY OF EVIDENCE SUGGESTS THAT THE REGULAR PRACTICE OF YOGA WOULD BE AN EFFECTIVE TREATMENT FOR STRESS. AIMS: TO DETERMINE THE KUNDALINI YOGA (KY) EFFECT, IMMEDIATE AND AFTER 3 MONTHS OF REGULAR PRACTICE, ON THE PERCEPTION OF PSYCHOLOGICAL STRESS AND THE SALIVARY LEVELS OF CORTISOL AND ALPHA-AMYLASE ACTIVITY. SETTINGS AND DESIGN: TO DETERMINE THE PSYCHOLOGICAL PERCEIVED STRESS, LEVELS OF CORTISOL AND ALPHA-AMYLASE ACTIVITY IN SALIVA, AND COMPARE BETWEEN THE PARTICIPANTS TO KY CLASSES PERFORMED FOR 3 MONTHS AND A GROUP THAT DOES NOT PRACTICE ANY TYPE OF YOGA. SUBJECTS AND METHODS: THE TOTAL SAMPLE CONSISTED OF 26 PEOPLE BETWEEN 18 AND 45-YEAR-OLD; 13 TAKING PART IN KY CLASSES GIVEN AT THE FACULTY OF DENTISTRY, UNIVERSITY OF CHILE AND 13 CONTROLS. SALIVARY SAMPLES WERE COLLECTED, ENZYME-LINKED IMMUNOSORBENT ASSAY WAS PERFORMED TO QUANTIFY CORTISOL AND KINETIC REACTION TEST WAS MADE TO DETERMINE ALPHA-AMYLASE ACTIVITY. PERCEIVED STRESS SCALE WAS APPLIED AT THE BEGINNING AND AT THE END OF THE INTERVENTION. STATISTICAL ANALYSIS USED: STATISTICAL ANALYSIS WAS APPLIED USING STATA V11.1 SOFTWARE. SHAPIRO-WILK TEST WAS USED TO DETERMINE DATA DISTRIBUTION. THE PAIRED ANALYSIS WAS FULFILLED BY T-TEST OR WILCOXON SIGNED-RANK TEST. T-TEST OR MANN-WHITNEY'S TEST WAS APPLIED TO COMPARE LONGITUDINAL DATA. A STATISTICAL SIGNIFICANCE WAS CONSIDERED WHEN P < 0.05. RESULTS: KY PRACTICE HAD AN IMMEDIATE EFFECT ON SALIVARY CORTISOL. THE ACTIVITY OF ALPHA-AMYLASE DID NOT SHOW SIGNIFICANT CHANGES. A SIGNIFICANT DECREASE OF PERCEIVED STRESS IN THE STUDY GROUP WAS FOUND. CONCLUSIONS: KY PRACTICE SHOWS AN IMMEDIATE EFFECT ON SALIVARY CORTISOL LEVELS AND ON PERCEIVED STRESS AFTER 3 MONTHS OF PRACTICE.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                     
5  726 19 EFFECT OF LAUGHTER YOGA ON SALIVARY CORTISOL AND DEHYDROEPIANDROSTERONE AMONG HEALTHY UNIVERSITY STUDENTS: A RANDOMIZED CONTROLLED TRIAL. OBJECTIVE: TO EXAMINE WHETHER LAUGHTER YOGA (LY), I.E., SIMULATED LAUGHTER, ALTERS CORTISOL AND DEHYDROEPIANDROSTERONE (DHEA) LEVELS AND CORTISOL/DHEA (C/D) RATIOS. METHODS: IN A RANDOMIZED CONTROLLED TRIAL, 120 HEALTHY UNIVERSITY STUDENTS WERE ALLOCATED TO EXPERIENCING LY, WATCHING A COMEDY MOVIE (SPONTANEOUS LAUGHTER), OR READING A BOOK. SALIVARY CORTISOL AND DHEA LEVELS WERE MEASURED IMMEDIATELY BEFORE, IMMEDIATELY AFTER, AND 30MIN AFTER THE INTERVENTION. RESULTS: CORTISOL LEVELS AND C/D RATIOS SIGNIFICANTLY DECREASED BY TIME IN THE LY AND COMEDY MOVIE GROUPS. SIGNIFICANT GROUP*TIME INTERACTIONS WERE FOUND BETWEEN THESE TWO GROUPS FOR CORTISOL LEVELS AND C/D RATIOS. DHEA LEVELS DID NOT CHANGE BY TIME IN THE LY GROUP. CONCLUSIONS: LY DECREASED CORTISOL LEVELS AND C/D RATIOS BUT DID NOT AFFECT DHEA LEVELS. SIMULATED AND SPONTANEOUS LAUGHTER DIFFERENTLY AFFECTED THE DYNAMICS OF CORTISOL LEVELS AND C/D RATIOS. EFFECT OF SPONTANEOUS LAUGHTER ON THE CORTISOL DYNAMICS LASTED LONGER THAN THAT OF SIMULATED LAUGHTER.

RESULTS: ANALYSIS OF COVARIANCE REVEALS SIGNIFICANT DECREASES IN ANXIETY (P < .001), DEPRESSION (P = .002), PERCEIVED STRESS (P < .001), 6 A.M. SALIVARY CORTISOL (P = .009), AND POOLED MEAN CORTISOL (P = .03) IN THE YOGA GROUP COMPARED WITH CONTROLS. THERE IS A SIGNIFICANT POSITIVE CORRELATION BETWEEN MORNING SALIVARY CORTISOL LEVEL AND ANXIETY AND DEPRESSION. CONCLUSION: YOGA MIGHT HAVE A ROLE IN MANAGING SELF-REPORTED PSYCHOLOGICAL DISTRESS AND MODULATING CIRCADIAN PATTERNS OF STRESS HORMONES IN EARLY BREAST CANCER PATIENTS UNDERGOING ADJUVANT RADIOTHERAPY.	2009	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
7  244 25 A YOGA AND COMPASSION MEDITATION PROGRAM REDUCES STRESS IN FAMILIAL CAREGIVERS OF ALZHEIMER'S DISEASE PATIENTS. FAMILIAL CAREGIVERS OF PATIENTS WITH ALZHEIMER'S DISEASE EXHIBIT REDUCED QUALITY OF LIFE AND INCREASED STRESS LEVELS. THE AIM OF THIS STUDY WAS TO INVESTIGATE THE EFFECTS OF AN 8-WEEK YOGA AND COMPASSION MEDITATION PROGRAM ON THE PERCEIVED STRESS, ANXIETY, DEPRESSION, AND SALIVARY CORTISOL LEVELS IN FAMILIAL CAREGIVERS. A TOTAL OF 46 VOLUNTEERS WERE RANDOMLY ASSIGNED TO PARTICIPATE IN A STRESS-REDUCTION PROGRAM FOR A 2-MONTH PERIOD (YOGA AND COMPASSION MEDITATION PROGRAM-YCMP GROUP) (N = 25) OR AN UNTREATED GROUP FOR THE SAME PERIOD OF TIME (CONTROL GROUP) (N = 21). THE LEVELS OF STRESS, ANXIETY, DEPRESSION, AND MORNING SALIVARY CORTISOL OF THE PARTICIPANTS WERE MEASURED BEFORE AND AFTER INTERVENTION. THE GROUPS WERE INITIALLY HOMOGENEOUS; HOWEVER, AFTER INTERVENTION, THE GROUPS DIVERGED SIGNIFICANTLY. THE YCMP GROUP EXHIBITED A REDUCTION OF THE STRESS (P < 0.05), ANXIETY (P < 0.000001), AND DEPRESSION (P < 0.00001) LEVELS, AS WELL AS A REDUCTION IN THE CONCENTRATION OF SALIVARY CORTISOL (P < 0.05). OUR STUDY SUGGESTS THAT AN 8-WEEK YOGA AND COMPASSION MEDITATION PROGRAM MAY OFFER AN EFFECTIVE INTERVENTION FOR REDUCING PERCEIVED STRESS, ANXIETY, DEPRESSION, AND SALIVARY CORTISOL IN FAMILIAL CAREGIVERS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
8 2743 26 YOGA PRACTICE IMPROVES EXECUTIVE FUNCTION BY ATTENUATING STRESS LEVELS. BACKGROUND: PROLONGED ACTIVATION OF THE HYPOTHALAMUS-PITUITARY-ADRENAL SYSTEM IS THOUGHT TO HAVE DELETERIOUS EFFECTS ON BRAIN FUNCTION. NEUROENDOCRINE STUDIES SUGGEST THAT BRAIN EXPOSURE TO HIGHER CORTISOL CONCENTRATIONS CONTRIBUTE TO COGNITIVE DEFICITS AS WE AGE. MIND-BODY TECHNIQUES SUCH AS YOGA HAVE SHOWN TO IMPROVE STRESS LEVELS BY RESTORING THE BODY'S SYMPATHETIC-PARASYMPATHETIC BALANCE. THE OBJECTIVE OF THIS STUDY WAS TO DETERMINE WHETHER YOGA PRACTICE MODERATED THE STRESS RESPONSE RESULTING IN IMPROVED EXECUTIVE FUNCTION. METHODS: SEDENTARY COMMUNITY DWELLING OLDER ADULTS (N=118, MEAN AGE=62.02) WERE RANDOMIZED TO AN 8-WEEK YOGA INTERVENTION OR A STRETCHING CONTROL GROUP. AT BASELINE AND FOLLOWING 8 WEEKS, ALL PARTICIPANTS COMPLETED MEASURES OF EXECUTIVE FUNCTION, SELF-REPORTED STRESS AND ANXIETY AND PROVIDED SALIVA SAMPLES BEFORE AND AFTER COGNITIVE TESTING TO ASSESS CORTISOL. RESULTS: YOGA PARTICIPANTS SHOWED IMPROVED ACCURACY ON EXECUTIVE FUNCTION MEASURES AND AN ATTENUATED CORTISOL RESPONSE COMPARED TO THEIR STRETCHING COUNTERPARTS WHO SHOWED INCREASED CORTISOL LEVELS AND POOR COGNITIVE PERFORMANCE AT FOLLOW UP. THE CHANGE IN CORTISOL LEVELS AS WELL AS SELF-REPORTED STRESS AND ANXIETY LEVELS PREDICTED PERFORMANCE ON THE RUNNING SPAN TASK, N-BACK WORKING MEMORY AND TASK SWITCHING PARADIGM (BETA'S=0.27-0.38, P'S</=0.05 FOR YOGA AND BETA'S=-0.37-0.47, P'S</=0.01 FOR STRETCHING CONTROL). CONCLUSION: EIGHT WEEKS OF REGULAR YOGA PRACTICE RESULTED IN IMPROVED WORKING MEMORY PERFORMANCE THAT WAS MEDIATED BY AN ATTENUATED RESPONSE TO STRESS AS MEASURED BY SELF-REPORT STRESS AND OBJECTIVE SALIVARY CORTISOL MEASUREMENTS. THIS TRIAL OFFERS EVIDENCE FOR NON-TRADITIONAL PHYSICAL ACTIVITY INTERVENTIONS SUCH AS YOGA THAT MAY BE HELPFUL IN RESTORING HPA BALANCE IN OLDER ADULTS, THEREBY PREVENTING COGNITIVE DECLINE.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
9  385 26 BENEFICIAL EFFECTS OF YOGA STRETCHING ON SALIVARY STRESS HORMONES AND PARASYMPATHETIC NERVE ACTIVITY. THIS STUDY AIMED TO DETERMINE THE EFFECT OF YOGA STRETCHING ON SALIVARY STRESS HORMONES AND CARDIAC AUTONOMIC NERVOUS SYSTEM. TO OUR KNOWLEDGE, THIS STUDY IS THE FIRST TO INVESTIGATE CHANGES IN CARDIAC AUTONOMIC NERVOUS SYSTEM AFTER YOGA STRETCHING. IN THIS CROSSOVER DESIGN STUDY, 10 ADULT MEN (AGE, 26.3 +/- 2.5 YEARS) WITHOUT YOGA EXPERIENCE PARTICIPATED IN THE REST AND YOGA TRIALS FOR 90 MIN. MEASUREMENTS WERE CARRIED OUT BEFORE (PRE), IMMEDIATELY (POST), 60 MIN, AND 120 MIN AFTER REST OR YOGA STRETCHING. SALIVA SAMPLES WERE COLLECTED BY CHEWING A STERILE COTTON BALL AT A FREQUENCY OF 60 CYCLES PER MINUTE. SALIVARY CORTISOL AND TESTOSTERONE CONCENTRATIONS WERE MEASURED USING AN ENZYME-LINKED IMMUNOSORBENT ASSAY. WITH THE SUBJECTS IN THE SITTING POSITION, HEART RATE VARIABILITY WAS MEASURED USING PULSE ANALYZER PLUS FOR 150 SECONDS. AS REGARDS RATE CHANGES, SALIVARY TESTOSTERONE LEVEL TENDED TO INCREASE (P = 0.088), TESTOSTERONE/CORTISOL RATIO SIGNIFICANTLY INCREASED (P < 0.05), AND CORTISOL LEVEL SIGNIFICANTLY DECREASED (P < 0.05) AT 120 MIN AFTER YOGA STRETCHING. THE SQUARE ROOT OF THE MEAN-SQUARED DIFFERENCES OF SUCCESSIVE NORMAL-TO-NORMAL INTERVALS AND NATURAL LOGARITHM HIGH-FREQUENCY COMPONENT, WHICH ARE INDICATORS OF PARASYMPATHETIC NERVE ACTIVITY, INCREASED AT 60 MIN (P < 0.05) AND 120 MIN (P < 0.05) IN THE YOGA TRIAL, RESPECTIVELY. IN CONCLUSION, YOGA STRETCHING CAN ENHANCE PARASYMPATHETIC NERVE ACTIVITY AND IMPROVE STRESS HORMONES. THEREFORE, YOGA STRETCHING MAY BE USEFUL TO COMPENSATE FOR PHYSICAL INACTIVITY AND INCREASE LIFE EXPECTANCY IN THE GENERAL POPULATION.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
10  984 35 EFFECTS OF HATHA YOGA AND AFRICAN DANCE ON PERCEIVED STRESS, AFFECT, AND SALIVARY CORTISOL. BACKGROUND: DANCE AND YOGA HAVE BEEN SHOWN TO PRODUCE IMPROVEMENTS IN PSYCHOLOGICAL WELL-BEING. PURPOSE: THE AIM OF THIS STUDY WAS TO EXAMINE SOME OF THE PSYCHOLOGICAL AND NEUROENDOCRINE RESPONSE TO THESE ACTIVITIES. METHODS: SIXTY-NINE HEALTHY COLLEGE STUDENTS PARTICIPATED IN ONE OF THREE 90-MIN CLASSES: AFRICAN DANCE (N = 21), HATHA YOGA (N= 18), OR A BIOLOGY LECTURE AS A CONTROL SESSION (N = 30). BEFORE AND AFTER EACH CONDITION PARTICIPANTS COMPLETED THE PERCEIVED STRESS SCALE (PSS), COMPLETED THE POSITIVE AFFECT AND NEGATIVE AFFECT SCHEDULE, AND PROVIDED A SALIVA SAMPLE FOR CORTISOL. RESULTS: THERE WERE SIGNIFICANT REDUCTIONS IN PSS AND NEGATIVE AFFECT (PS < .0001) AND TIME X TREATMENT INTERACTIONS (PS < .0001) SUCH THAT AFRICAN DANCE AND HATHA YOGA SHOWED SIGNIFICANT DECLINES, WHEREAS THERE WAS NO SIGNIFICANT CHANGE IN BIOLOGY LECTURE. THERE WAS NO SIGNIFICANT MAIN EFFECT FOR POSITIVE AFFECT (P = .53), HOWEVER THERE WAS A SIGNIFICANT INTERACTION EFFECT (P < .001) SUCH THAT POSITIVE AFFECT INCREASED IN AFRICAN DANCE, DECREASED IN BIOLOGY LECTURE, AND DID NOT CHANGE SIGNIFICANTLY IN HATHA YOGA. THERE WAS A SIGNIFICANT MAIN EFFECT FOR SALIVARY CORTISOL (P < .05) AND A SIGNIFICANT INTERACTION EFFECT (P < .0001) SUCH THAT CORTISOL INCREASED IN AFRICAN DANCE, DECREASED IN HATHA YOGA, AND DID NOT CHANGE IN BIOLOGY. CHANGES IN CORTISOL WERE NOT SIGNIFICANTLY RELATED TO CHANGES IN PSYCHOLOGICAL VARIABLES ACROSS TREATMENTS. THERE WAS 1 SIGNIFICANT INTERACTION EFFECT (P = .04) SUCH THAT CHANGE IN POSITIVE AFFECT AND CHANGE IN CORTISOL WERE NEGATIVELY CORRELATED IN HATHA YOGA BUT POSITIVELY CORRELATED IN AFRICA DANCE AND BIOLOGY. CONCLUSIONS: BOTH AFRICAN DANCE AND HATHA YOGA REDUCED PERCEIVED STRESS AND NEGATIVE AFFECT. CORTISOL INCREASED IN AFRICAN DANCE AND DECREASED IN HATHA YOGA. THEREFORE, EVEN WHEN THESE INTERVENTIONS PRODUCE SIMILAR POSITIVE PSYCHOLOGICAL EFFECTS, THE EFFECTS MAY BE VERY DIFFERENT ON PHYSIOLOGICAL STRESS PROCESSES. ONE FACTOR THAT MAY HAVE PARTICULAR SALIENCE IS THAT AMOUNT OF PHYSIOLOGICAL AROUSAL PRODUCED BY THE INTERVENTION.	2004	
                                                                                                                                                                                                                                                                                                                                               
11 1361 26 IMMEDIATE STRESS REDUCTION EFFECTS OF YOGA DURING PREGNANCY: ONE GROUP PRE-POST TEST. BACKGROUND: EXCESSIVE STRESS DURING PREGNANCY MAY CAUSE MENTAL DISORDERS IN PREGNANT WOMEN AND INHIBIT FETAL GROWTH. YOGA MAY ALLEVIATE STRESS DURING PREGNANCY. AIM: TO VERIFY THE IMMEDIATE EFFECTS OF YOGA ON STRESS RESPONSE DURING PREGNANCY. METHODS: ONE GROUP PRE-POST TEST WAS CONDUCTED AT A HOSPITAL IN JAPAN. WE RECRUITED 60 HEALTHY PRIMIPARAS WITHOUT COMPLICATIONS AND ASKED THEM TO ATTEND YOGA CLASSES TWICE A MONTH AND TO PRACTICE YOGA AT THEIR HOMES USING DVD 3 TIMES A WEEK FROM 20 GESTATIONAL WEEKS UNTIL CHILDBIRTH. SALIVARY CORTISOL AND ALPHA-AMYLASE CONCENTRATION WERE MEASURED BEFORE AND AFTER YOGA CLASSES AT TIME 1 (27-32 GESTATIONAL WEEKS) AND TIME 2 (34-37 GESTATIONAL WEEKS). SUBJECTIVE MOOD WAS ASSESSED USING THE PROFILE OF MOOD STATES. SALIVA VALUES AND MOOD SCORES BEFORE AND AFTER EACH YOGA CLASS WERE COMPARED USING PAIRED T-TEST AND WILCOXON RANK-SUM TEST, RESPECTIVELY. FINDINGS: WE ANALYZED 44 AND 35 WOMEN AT TIME 1 AND TIME 2, RESPECTIVELY. THE MEAN SALIVARY CORTISOL CONCENTRATION DECLINED SIGNIFICANTLY AFTER EACH YOGA CLASS [TIME 1: 0.36-0.26MUG/DL (P<0.001), TIME 2: 0.32-0.26MUG/DL (P=0.001)]. THE MEAN SALIVARY ALPHA-AMYLASE CONCENTRATION ALSO DECREASED SIGNIFICANTLY FOLLOWING EACH CLASS [TIME 1: 72.2-50.8KU/L (P=0.001), TIME 2: 70.6-52.7KU/L (P=0.006)]. THE SCORES FOR NEGATIVE DIMENSIONS OF MOOD (TRAIT-ANXIETY, DEPRESSION, ANGER-HOSTILITY, FATIGUE, AND CONFUSION) DECREASED SIGNIFICANTLY. THE SCORES OF VIGOR FOR A POSITIVE DIMENSION OF MOOD SIGNIFICANTLY INCREASED. CONCLUSION: THIS STUDY INDICATED THE IMMEDIATE STRESS REDUCTION EFFECTS OF YOGA DURING PREGNANCY.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
12  951 25 EFFECTS OF A CLASSROOM-BASED YOGA INTERVENTION ON CORTISOL AND BEHAVIOR IN SECOND- AND THIRD-GRADE STUDENTS: A PILOT STUDY. THIS UNCONTROLLED PILOT STUDY EXAMINED THE EFFECTS OF A CLASSROOM-BASED YOGA INTERVENTION ON CORTISOL CONCENTRATIONS AND PERCEIVED BEHAVIOR IN CHILDREN. A 10-WEEK YOGA 4 CLASSROOMS INTERVENTION WAS IMPLEMENTED IN ONE SECOND-GRADE AND ONE THIRD-GRADE CLASSROOM. STUDENTS' SALIVARY CORTISOL RESPONSES WERE ASSESSED AT 3 TIME POINTS. CLASSROOM TEACHERS ALSO DOCUMENTED THEIR PERCEPTIONS OF THE EFFECTS OF THE INTERVENTION ON STUDENTS' COGNITIVE, SOCIAL, AND EMOTIONAL SKILLS. SECOND, BUT NOT THIRD, GRADERS SHOWED A SIGNIFICANT DECREASE IN BASELINE CORTISOL FROM BEFORE TO AFTER THE INTERVENTION. SECOND AND THIRD GRADERS BOTH SHOWED SIGNIFICANT DECREASES IN CORTISOL FROM BEFORE TO AFTER A COGNITIVE TASK, BUT NEITHER GRADE SHOWED ADDITIONAL DECREASES FROM BEFORE TO AFTER A SINGLE YOGA CLASS. THE SECOND-GRADE TEACHER PERCEIVED SIGNIFICANT IMPROVEMENTS IN SEVERAL ASPECTS HIS/HER STUDENTS' BEHAVIOR. THE THIRD-GRADE TEACHER PERCEIVED SOME, BUT FEWER, IMPROVEMENTS IN HIS/HER STUDENTS' BEHAVIOR. RESULTS SUGGEST THAT SCHOOL-BASED YOGA MAY BE ADVANTAGEOUS FOR STRESS MANAGEMENT AND BEHAVIOR.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
13 1390 20 IMPACT OF SUDARSHAN KRIYA YOGA ON SALIVARY PH: AN EXPLORATORY PILOT STUDY. INTRODUCTION: SALIVA IS INCREASINGLY USED AS A DIAGNOSTIC TOOL AS IT IS NON-INVASIVE, EASILY ACCESSIBLE, AND LESS STRESSFUL COMPARED TO BLOOD SAMPLING. SALIVA HAS A VITAL ROLE IN MAINTAINING ORAL HEALTH. IT IS NECESSARY FOR THE SALIVARY PH TO BE NEUTRAL IN THE ORAL CAVITY FOR THE OPTIMAL FUNCTIONING OF ITS COMPONENTS. STRESS HAS AN EFFECT ON SALIVARY PH. OBJECTIVE: TO STUDY THE EFFECT OF A MIND-BODY INTERVENTION LIKE SUDARSHAN KRIYA YOGA (SKY) ON THE SALIVARY PH. METHODS AND MATERIALS: AN EXPLORATORY PILOT STUDY INVOLVING AN OPEN TRIAL ON 321 HEALTHY INDIVIDUALS WHO WERE NOVICE TO SKY WAS CONDUCTED. THE SALIVARY PH WAS MEASURED BEFORE AND AFTER A SINGLE 90-MIN SESSION OF SKY. RESULTS: THE SALIVARY PH CONTINUED TO BE NEUTRAL AFTER THE INTERVENTION IN THE GROUP THAT HAD INITIAL NEUTRAL PH. THERE WAS A STATISTICALLY SIGNIFICANT SHIFT OF PH TOWARDS NEUTRAL IN BOTH THE GROUPS THAT HAD EITHER ACIDIC OR ALKALINE PH INITIALLY. CONCLUSION: MIND-BODY INTERVENTIONS LIKE SKY MODULATE THE SALIVARY PH TO BRING IT TO THE RANGE OF OPTIMAL FUNCTIONING. THIS PILOT STUDY PROVIDES INFORMATION FOR FUTURE LONG-TERM STUDIES THAT CAN BE IMPLEMENTED WITH MEASURES OF ANXIETY AND STRESS ALONG WITH MEASURING OTHER SALIVARY BIOMARKERS.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
14  302 26 AN EIGHT-WEEK YOGA INTERVENTION IS ASSOCIATED WITH IMPROVEMENTS IN PAIN, PSYCHOLOGICAL FUNCTIONING AND MINDFULNESS, AND CHANGES IN CORTISOL LEVELS IN WOMEN WITH FIBROMYALGIA. OBJECTIVES: FIBROMYALGIA (FM) IS A CHRONIC CONDITION CHARACTERIZED BY WIDESPREAD MUSCULOSKELETAL PAIN, FATIGUE, DEPRESSION, AND HYPOCORTISOLISM. TO DATE, PUBLISHED STUDIES HAVE NOT INVESTIGATED THE EFFECTS OF YOGA ON CORTISOL IN FM. THIS PILOT STUDY USED A TIME SERIES DESIGN TO EVALUATE PAIN, PSYCHOLOGICAL VARIABLES, MINDFULNESS, AND CORTISOL IN WOMEN WITH FM BEFORE AND AFTER A YOGA INTERVENTION. METHODS: PARTICIPANTS (N = 22) WERE RECRUITED FROM THE COMMUNITY TO PARTICIPATE IN A 75 MINUTE YOGA CLASS TWICE WEEKLY FOR 8 WEEKS. QUESTIONNAIRES CONCERNING PAIN (INTENSITY, UNPLEASANTNESS, QUALITY, SUM OF LOCAL AREAS OF PAIN, CATASTROPHIZING, ACCEPTANCE, DISABILITY), ANXIETY, DEPRESSION, AND MINDFULNESS WERE ADMINISTERED PRE-, MID- AND POST-INTERVENTION. SALIVARY CORTISOL SAMPLES WERE COLLECTED THREE TIMES A DAY FOR EACH OF TWO DAYS, PRE- AND POST-INTERVENTION. RESULTS: REPEATED MEASURES ANALYSIS OF VARIANCE (ANOVA) REVEALED THAT MEAN +/- STANDARD DEVIATION (SD) SCORES IMPROVED SIGNIFICANTLY (P < 0.05) FROM PRE- TO POST-INTERVENTION FOR CONTINUOUS PAIN (PRE: 5.18 +/- 1.72; POST: 4.44 +/- 2.03), PAIN CATASTROPHIZING (PRE: 25.33 +/- 14.77; POST: 20.40 +/- 17.01), PAIN ACCEPTANCE (PRE: 60.47 +/- 23.43; POST: 65.50 +/- 22.93), AND MINDFULNESS (PRE: 120.21 +/- 21.80; POST: 130.63 +/- 20.82). INTENTION-TO-TREAT ANALYSIS SHOWED THAT MEDIAN AUC FOR POST-INTERVENTION CORTISOL (263.69) WAS SIGNIFICANTLY HIGHER (P < 0.05) THAN MEDIAN AUC FOR PRE-INTERVENTION LEVELS (189.46). MEDIATION ANALYSIS REVEALED THAT MID-INTERVENTION MINDFULNESS SCORES SIGNIFICANTLY (P < 0.05) MEDIATED THE RELATIONSHIP BETWEEN PRE- AND POST-INTERVENTION PAIN CATASTROPHIZING SCORES. DISCUSSION: THE RESULTS SUGGEST THAT A YOGA INTERVENTION MAY REDUCE PAIN AND CATASTROPHIZING, INCREASE ACCEPTANCE AND MINDFULNESS, AND ALTER TOTAL CORTISOL LEVELS IN WOMEN WITH FM. THE CHANGES IN MINDFULNESS AND CORTISOL LEVELS MAY PROVIDE PRELIMINARY EVIDENCE FOR MECHANISMS OF A YOGA PROGRAM FOR WOMEN WITH FM. FUTURE STUDIES SHOULD USE AN RCT DESIGN WITH A LARGER SAMPLE SIZE.	2011	
                                                                                                                                                                                                                                                                                               
15 1549 32 LAUGHTER YOGA REDUCES THE CORTISOL RESPONSE TO ACUTE STRESS IN HEALTHY INDIVIDUALS. STRESS IS ONE OF THE FOREMOST CONTRIBUTORS TO THE DEVELOPMENT OF PSYCHIATRIC DISEASES. SINCE THE PREVALENCE OF STRESS-RELATED COMPLAINTS IS INCREASING, WE ARE IN NEED FOR AFFORDABLE AND EFFECTIVE TREATMENT ALTERNATIVES. LAUGHTER YOGA (LY), A POPULAR METHOD ENCOURAGING PARTICIPANTS TO SIMULATE LAUGHTER AND PARTICIPATE IN YOGIC BREATHING EXERCISES, IS HYPOTHESIZED TO BUFFER NEGATIVE EFFECTS OF STRESS. ALTHOUGH WIDELY PRACTICED, EMPIRICAL EVIDENCE FOR BENEFICIAL EFFECTS OF LY IS SCARCE. WE INVESTIGATED THE ACUTE EFFECTS OF A SINGLE 30-MIN LY SESSION ON THE AUTONOMIC, ENDOCRINE AND PSYCHOLOGICAL RESPONSE TO A STANDARDIZED PSYCHOSOCIAL STRESSOR. THIRTY-FIVE HEALTHY SUBJECTS (51% FEMALE) WERE RANDOMLY ASSIGNED TO EXPERIENCE EITHER A LY (N = 11), A RELAXATION BREATHING (N = 12) OR A (NON-INTERVENTION) CONTROL (N = 12) SESSION PRIOR TO THEIR EXPOSURE TO THE TRIER SOCIAL STRESS TEST FOR GROUPS (TSST-G). SALIVARY CORTISOL, SALIVARY ALPHA AMYLASE, AND SUBJECTIVE STRESS WERE ASSESSED REPEATEDLY THROUGHOUT THE EXPERIMENT. WE EXPECTED THAT LY AND RELAXATION BREATHING GROUP EACH SHOW A DOWNREGULATION OF STRESS RESPONSE INDICES COMPARED TO THE CONTROL GROUP. FURTHER, WE EXPECTED THAT LY HAS BENEFICIAL EFFECTS COMPARED TO RELAXATION BREATHING. THE GROUPS DID NOT DIFFER IN SALIVARY CORTISOL, ALPHA AMYLASE OR SUBJECTIVE STRESS REACTIVITY DURING THE 30-MIN INTERVENTION. HOWEVER, IN RESPONSE TO THE TSST-G, THE LY, BUT NEITHER THE RELAXATION BREATHING, NOR THE CONTROL CONDITION, SHOWED AN ATTENUATED CORTISOL STRESS RESPONSE. THESE FINDINGS HIGHLIGHT THE POTENTIAL OF LY TO BUFFER THE ENDOCRINE STRESS RESPONSE. THEREFORE, LY COULD BE USED AS A CHEAP AND EASILY-TO-IMPLEMENT ADD-ON TO MORE TRADITIONAL STRESS INTERVENTIONS. LAY SUMMARY IN RECENT YEARS, MORE AND MORE PEOPLE HAVE REPORTED TO FEEL STRESSED. ALTHOUGH OUR BODY IS WELL EQUIPPED TO DEAL WITH ACUTE STRESS, CHRONIC STRESS CAN TIRE OUR SYSTEM AND CONTRIBUTE TO ILLNESS IN THE LONG RUN. THEREFORE, WE NEED AFFORDABLE AND EFFECTIVE MEASURES TO REDUCE STRESS. IN THIS STUDY WE HAVE INVESTIGATED WHETHER A SINGLE LAUGHTER YOGA SESSION CAN HELP US TO DEAL WITH ACUTE STRESS. ALTHOUGH LAUGHTER YOGA DID NOT CHANGE HOW STRESSFUL A SITUATION WAS PERCEIVED, IT REDUCED THE AMOUNT OF STRESS HORMONES THAT WERE RELEASED IN RESPONSE TO THE SITUATION. AS SUCH, LAUGHTER YOGA MIGHT BE A CHEAP AND EASILY-TO-IMPLEMENT ADD-ON TO MORE TRADITIONAL STRESS REDUCTION INTERVENTIONS.	2021	

16 1874 32 RAPID STRESS REDUCTION AND ANXIOLYSIS AMONG DISTRESSED WOMEN AS A CONSEQUENCE OF A THREE-MONTH INTENSIVE YOGA PROGRAM. BACKGROUND: EMOTIONAL DISTRESS IS AN INCREASING PUBLIC HEALTH PROBLEM AND HATHA YOGA HAS BEEN CLAIMED TO INDUCE STRESS REDUCTION AND EMPOWERMENT IN PRACTICING SUBJECTS. WE AIMED TO EVALUATE POTENTIAL EFFECTS OF IYENGAR HATHA YOGA ON PERCEIVED STRESS AND ASSOCIATED PSYCHOLOGICAL OUTCOMES IN MENTALLY DISTRESSED WOMEN. MATERIAL/METHODS: A CONTROLLED PROSPECTIVE NON-RANDOMIZED STUDY WAS CONDUCTED IN 24 SELF-REFERRED FEMALE SUBJECTS (MEAN AGE 37.9+/-7.3 YEARS) WHO PERCEIVED THEMSELVES AS EMOTIONALLY DISTRESSED. SUBJECTS WERE OFFERED PARTICIPATION IN ONE OF TWO SUBSEQUENTIAL 3-MONTHS YOGA PROGRAMS. GROUP 1 (N=16) PARTICIPATED IN THE FIRST CLASS, GROUP 2 (N=8) SERVED AS A WAITING LIST CONTROL. DURING THE YOGA COURSE, SUBJECTS ATTENDED TWO-WEEKLY 90-MIN IYENGAR YOGA CLASSES. OUTCOME WAS ASSESSED ON ENTRY AND AFTER 3 MONTHS BY COHEN PERCEIVED STRESS SCALE, STATE-TRAIT ANXIETY INVENTORY, PROFILE OF MOOD STATES, CESD-DEPRESSION SCALE, BF-S/BF-S' WELL-BEING SCALES, FREIBURG COMPLAINT LIST AND RATINGS OF PHYSICAL WELL-BEING. SALIVARY CORTISOL LEVELS WERE MEASURED BEFORE AND AFTER AN EVENING YOGA CLASS IN A SECOND SAMPLE. RESULTS: COMPARED TO WAITING-LIST, WOMEN WHO PARTICIPATED IN THE YOGA-TRAINING DEMONSTRATED PRONOUNCED AND SIGNIFICANT IMPROVEMENTS IN PERCEIVED STRESS (P<0.02), STATE AND TRAIT ANXIETY (P<0.02 AND P<0.01, RESPECTIVELY), WELL-BEING (P<0.01), VIGOR (P<0.02), FATIGUE (P<0.02) AND DEPRESSION (P<0.05). PHYSICAL WELL-BEING ALSO INCREASED (P<0.01), AND THOSE SUBJECTS SUFFERING FROM HEADACHE OR BACK PAIN REPORTED MARKED PAIN RELIEF. SALIVARY CORTISOL DECREASED SIGNIFICANTLY AFTER PARTICIPATION IN A YOGA CLASS (P<0.05). CONCLUSIONS: WOMEN SUFFERING FROM MENTAL DISTRESS PARTICIPATING IN A 3-MONTH IYENGAR YOGA CLASS SHOW SIGNIFICANT IMPROVEMENTS ON MEASURES OF STRESS AND PSYCHOLOGICAL OUTCOMES. FURTHER INVESTIGATION OF YOGA WITH RESPECT TO PREVENTION AND TREATMENT OF STRESS-RELATED DISEASE AND OF UNDERLYING MECHANISM IS WARRANTED.	2005	
                                                                                                                                                                                                                                                                                                                                                                                                                                               
17 1330 22 HOLISTIC NURSING IN PRACTICE: MINDFULNESS-BASED YOGA AS AN INTERVENTION TO MANAGE STRESS AND BURNOUT. PURPOSE: EFFECTS OF A MINDFULNESS-BASED (MB) YOGA PRACTICE ON STRESS, BURNOUT, AND INDICATORS OF WELL-BEING AMONG NURSES AND HEALTH CARE PROFESSIONALS (HCPS). DESIGN: A RANDOMIZED CONTROLLED TRIAL, 80 HCPS ASSIGNED TO EITHER MB YOGA INTERVENTION OR CONTROL GROUP. METHOD: THE MB YOGA INTERVENTION GROUP (N = 41) ATTENDED WEEKLY YOGA CLASSES AND PRACTICED YOGA INDEPENDENTLY. THE CONTROL GROUP (N = 39) DID NOT RECEIVE THE YOGA INTERVENTION. STUDY PARTICIPANTS COMPLETED PRE- AND POSTINTERVENTION QUESTIONNAIRES, INSTRUMENTS INCLUDED (A) PERCEIVED STRESS SCALE; (B) MASLACH BURNOUT INVENTORY; (C) VITALITY SUBSCALE OF THE MEDICAL OUTCOMES STUDY SHORT FORM-36; (D) GLOBAL SLEEP QUALITY ITEM, (E) MINDFULNESS AWARENESS SURVEY, AND (F) SUBSCALE OF THE BRIEF SERENITY SCALE. DIURNAL SALIVARY CORTISOL AND BLOOD PRESSURE WERE ASSESSED PRE AND POSTINTERVENTION. RESULTS: SIGNIFICANT IMPROVEMENTS (P < .01) NOTED IN MB YOGA COMPARED WITH CONTROL FOR SELF-REPORTED FACTORS, INCLUDING STRESS (PERCEIVED STRESS SCALE), BURNOUT (MASLACH BURNOUT INVENTORY), VITALITY (MEDICAL OUTCOMES STUDY SHORT FORM-36), SLEEP (GSQ), SERENITY/INNER HAVEN (IH), AND MINDFULNESS (MINDFULNESS AWARENESS SURVEY). DIURNAL CORTISOL SLOPES AND BLOOD PRESSURE WERE NOT SIGNIFICANTLY IMPROVED. CONCLUSION: THE MB YOGA INTERVENTION HAD A STATISTICALLY SIGNIFICANT EFFECT ON THE HEALTH AND WELL-BEING OF NURSES AND HCPS, MOST SPECIFICALLY FOR MEASURES OF STRESS; PERCEIVED STRESS, BURNOUT, VITALITY, SLEEP QUALITY, SERENITY, AND MINDFULNESS.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
18  743 25 EFFECT OF RESTORATIVE YOGA VS. STRETCHING ON DIURNAL CORTISOL DYNAMICS AND PSYCHOSOCIAL OUTCOMES IN INDIVIDUALS WITH THE METABOLIC SYNDROME: THE PRYSMS RANDOMIZED CONTROLLED TRIAL. PURPOSE: CHRONIC STIMULATION AND DYSREGULATION OF THE NEUROENDOCRINE SYSTEM BY STRESS MAY CAUSE METABOLIC ABNORMALITIES. WE ESTIMATED HOW MUCH CORTISOL AND PSYCHOSOCIAL OUTCOMES IMPROVED WITH A RESTORATIVE YOGA (RELAXATION) VERSUS A LOW IMPACT STRETCHING INTERVENTION FOR INDIVIDUALS WITH THE METABOLIC SYNDROME. METHODS: WE CONDUCTED A 1-YEAR MULTI-CENTER RANDOMIZED CONTROLLED TRIAL (6-MONTH INTERVENTION AND 6-MONTH MAINTENANCE PHASE) OF RESTORATIVE YOGA VS. STRETCHING. PARTICIPANTS COMPLETED SURVEYS TO ASSESS DEPRESSION, SOCIAL SUPPORT, POSITIVE AFFECT, AND STRESS AT BASELINE, 6 MONTHS AND 12 MONTHS. FOR EACH ASSESSMENT, WE COLLECTED SALIVA AT FOUR POINTS DAILY FOR THREE DAYS AND COLLECTED RESPONSE TO DEXAMETHASONE ON THE FOURTH DAY FOR ANALYSIS OF DIURNAL CORTISOL DYNAMICS. WE ANALYZED OUR DATA USING MULTIVARIATE REGRESSION MODELS, CONTROLLING FOR STUDY SITE, MEDICATIONS (ANTIDEPRESSANTS, HORMONE THERAPY), BODY MASS INDEX, AND BASELINE CORTISOL VALUES. RESULTS: PSYCHOSOCIAL OUTCOME MEASURES WERE AVAILABLE FOR 171 STUDY PARTICIPANTS AT BASELINE, 140 AT 6 MONTHS, AND 132 AT 1 YEAR. COMPLETE CORTISOL DATA WERE AVAILABLE FOR 136 OF 171 STUDY PARTICIPANTS (72 IN RESTORATIVE YOGA AND 64 IN STRETCHING) AND WERE ONLY AVAILABLE AT BASELINE AND 6 MONTHS. AT 6 MONTHS, THE STRETCHING GROUP HAD DECREASED CORTISOL AT WAKING AND BEDTIME COMPARED TO THE RESTORATIVE YOGA GROUP. THE PATTERN OF CHANGES IN STRESS MIRRORED THIS IMPROVEMENT, WITH THE STRETCHING GROUP SHOWING REDUCTIONS IN CHRONIC STRESS SEVERITY AND PERSEVERATIVE THOUGHTS ABOUT THEIR STRESS. PERCEIVED STRESS DECREASED BY 1.5 POINTS (-0.4; 3.3, P=0.11) AT 6 MONTHS, AND BY 2.0 POINTS (0.1; 3.9, P=0.04) AT 1 YEAR IN THE STRETCHING COMPARED TO RESTORATIVE YOGA GROUPS. POST HOC ANALYSES SUGGEST THAT IN THE STRETCHING GROUP ONLY, PERCEIVED INCREASES IN SOCIAL SUPPORT (PARTICULARLY FEELINGS OF BELONGING), BUT NOT CHANGES IN STRESS WERE RELATED TO IMPROVED CORTISOL DYNAMICS. CONCLUSIONS: WE FOUND SIGNIFICANT DECREASES IN SALIVARY CORTISOL, CHRONIC STRESS SEVERITY, AND STRESS PERCEPTION IN THE STRETCHING GROUP COMPARED TO THE RESTORATIVE YOGA GROUP. GROUP SUPPORT DURING THE INTERACTIVE STRETCH CLASSES MAY HAVE CONTRIBUTED TO THESE CHANGES.	2014	
                                                                                                                
19   51 20 A COMPARATIVE RANDOMISED CONTROLLED TRIAL OF THE EFFECTS OF BRAIN WAVE VIBRATION TRAINING, IYENGAR YOGA, AND MINDFULNESS ON MOOD, WELL-BEING, AND SALIVARY CORTISOL. THIS RANDOMISED TRIAL COMPARED THE EFFECTS OF BRAIN WAVE VIBRATION (BWV) TRAINING, WHICH INVOLVES RHYTHMIC YOGA-LIKE MEDITATIVE EXERCISES, WITH IYENGAR YOGA AND MINDFULNESS. IYENGAR PROVIDED A CONTRAST FOR THE PHYSICAL COMPONENTS AND MINDFULNESS FOR THE "MENTAL" COMPONENTS OF BWV. 35 HEALTHY ADULTS COMPLETED 10 75-MINUTE CLASSES OF BWV, IYENGAR, OR MINDFULNESS OVER FIVE WEEKS. PARTICIPANTS WERE ASSESSED AT PRE- AND POSTINTERVENTION FOR MOOD, SLEEP, MINDFULNESS, ABSORPTION, HEALTH, MEMORY, AND SALIVARY CORTISOL. BETTER OVERALL MOOD AND VITALITY FOLLOWED BOTH BWV AND IYENGAR TRAINING, WHILE THE BWV GROUP ALONE HAD IMPROVED DEPRESSION AND SLEEP LATENCY. MINDFULNESS PRODUCED A COMPARATIVELY GREATER INCREASE IN ABSORPTION. ALL INTERVENTIONS IMPROVED STRESS AND MINDFULNESS, WHILE NO CHANGES OCCURRED IN HEALTH, MEMORY, OR SALIVARY CORTISOL. IN CONCLUSION, INCREASED WELL-BEING FOLLOWED TRAINING IN ALL THREE PRACTICES, INCREASED ABSORPTION WAS SPECIFIC TO MINDFULNESS, WHILE BWV WAS UNIQUE IN ITS BENEFITS TO DEPRESSION AND SLEEP LATENCY, WARRANTING FURTHER RESEARCH.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
20 1015 25 EFFECTS OF PRENATAL YOGA ON WOMEN'S STRESS AND IMMUNE FUNCTION ACROSS PREGNANCY: A RANDOMIZED CONTROLLED TRIAL. OBJECTIVE: THE EFFECTS OF PRENATAL YOGA ON BIOLOGICAL INDICATORS HAVE NOT BEEN WIDELY STUDIED. THUS, WE COMPARED CHANGES IN STRESS AND IMMUNITY SALIVARY BIOMARKERS FROM 16 TO 36 WEEKS' GESTATION BETWEEN WOMEN RECEIVING PRENATAL YOGA AND THOSE RECEIVING ROUTINE PRENATAL CARE. DESIGN: FOR THIS LONGITUDINAL, PROSPECTIVE, RANDOMIZED CONTROLLED TRIAL, WE RECRUITED 94 HEALTHY PREGNANT WOMEN AT 16 WEEKS' GESTATION THROUGH CONVENIENCE SAMPLING FROM A PRENATAL CLINIC IN TAIPEI. PARTICIPANTS WERE RANDOMLY ASSIGNED TO INTERVENTION (N=48) OR CONTROL (N=46) GROUPS USING CLINSTAT BLOCK RANDOMIZATION. INTERVENTION: THE 20-WEEK INTERVENTION COMPRISED TWO WEEKLY 70-MIN YOGA SESSIONS LED BY A MIDWIFE CERTIFIED AS A YOGA INSTRUCTOR; THE CONTROL GROUP RECEIVED ONLY ROUTINE PRENATAL CARE. MAIN OUTCOME MEASURES: IN BOTH GROUPS, PARTICIPANTS' SALIVARY CORTISOL AND IMMUNOGLOBULIN A LEVELS WERE COLLECTED BEFORE AND AFTER YOGA EVERY 4 WEEKS FROM 16 TO 36 WEEKS' GESTATION. RESULTS: THE INTERVENTION GROUP HAD LOWER SALIVARY CORTISOL (P<0.001) AND HIGHER IMMUNOGLOBULIN A (P<0.001) LEVELS IMMEDIATELY AFTER YOGA THAN THE CONTROL GROUP. SPECIFICALLY, THE INTERVENTION GROUP HAD SIGNIFICANTLY HIGHER LONG-TERM SALIVARY IMMUNOGLOBULIN A LEVELS THAN THE CONTROL GROUP (P=0.018), AND INFANTS BORN TO WOMEN IN THE INTERVENTION GROUP WEIGHED MORE THAN THOSE BORN TO THE CONTROL GROUP (P<0.001). CONCLUSION: PRENATAL YOGA SIGNIFICANTLY REDUCED PREGNANT WOMEN'S STRESS AND ENHANCED THEIR IMMUNE FUNCTION. CLINICIANS SHOULD LEARN THE MECHANISMS OF YOGA AND ITS EFFECTS ON PREGNANT WOMEN. OUR FINDINGS CAN GUIDE CLINICIANS TO HELP PREGNANT WOMEN ALLEVIATE THEIR STRESS AND ENHANCE THEIR IMMUNE FUNCTION.	2017
