1 1835 68 PSYCHOPHYSIOLOGICAL CHANGES AT THE TIME OF EXAMINATION IN MEDICAL STUDENTS BEFORE AND AFTER THE PRACTICE OF YOGA AND RELAXATION. THE EFFECT OF YOGA AND RELAXATION CHANGES IN PSYCHOPHYSIOLOGICAL PARAMETERS IN RESPONSE TO THE STRESS OF EXAMINATION IN 75 MEDICAL STUDENTS WAS STUDIED. INITIALLY FIVE PARAMETERS (ANXIETY LEVEL, HEART RATE, BLOOD PRESSURE, GALVANIC SKIN RESISTANCE AND CHOICE REACTION TIME) WERE RECORDED, A MONTH BEFORE THE EXAMINATION AND ON THE DAY OF EXAMINATION. STUDENTS WERE THEN RANDOMLY DIVIDED INTO 3 GROUP OF 25 EACH. ONE GROUP PRACTICED YOGA (GROUP- Y), AND ANOTHER GROUP PRACTICED RELAXATION (GROUP-R) REGULARLY FOR THREE MONTHS. THE THIRD GROUP WAS CONTROL GROUP (GROUP-C). ALL THE PARAMETERS WERE RECORDED AFTER THE CHANGES IN ANXIETY LEVEL, HEART RATE, BLOOD PRESSURE, AND GALVANIC SKIN RESISTANCE IN RESPONSE TO STRESS OF EXAMINATION WERE SIGNIFICANTLY ATTENUATED AND THERE WAS SIGNIFICANT IMPROVEMENT IN CHOICE REACTION TIME IN GROUP-Y AND GROUP-R AS COMPARED TO GROUP-C AFTER YOGA AND RELAXATION.	1998	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
2  209 25 A SINGLE SESSION OF HATHA YOGA IMPROVES STRESS REACTIVITY AND RECOVERY AFTER AN ACUTE PSYCHOLOGICAL STRESS TASK-A COUNTERBALANCED, RANDOMIZED-CROSSOVER TRIAL IN HEALTHY INDIVIDUALS. OBJECTIVES: YOGA IS PROMOTED AS AN ANTI-STRESS ACTIVITY, HOWEVER, LITTLE IS KNOWN ABOUT THE MECHANISMS THROUGH WHICH IT ACTS. THE PRESENT STUDY INVESTIGATED THE ACUTE EFFECTS OF A HATHA YOGA SESSION, DISPLAYED ON A VIDEO, ON THE RESPONSE TO AND RECOVERY FROM AN ACUTE PSYCHOLOGICAL STRESSOR. METHODS: TWENTY-FOUR HEALTHY YOUNG ADULTS TOOK PART IN A COUNTERBALANCED, RANDOMIZED-CROSSOVER TRIAL, WITH A YOGA AND A CONTROL CONDITION (WATCHING TV). PARTICIPANTS ATTENDED THE LABORATORY IN THE AFTERNOON ON TWO DAYS AND EACH SESSION COMPRISED A BASELINE, CONTROL OR YOGA TASK, STRESS TASK AND RECOVERY. BLOOD PRESSURE (BP), HEART RATE (HR) AND SALIVARY CORTISOL RESPONSES WERE MEASURED. STATE COGNITIVE- AND SOMATIC-ANXIETY ALONG WITH SELF-CONFIDENCE WERE ASSESSED BEFORE AND AFTER THE STRESSOR. RESULTS: ALTHOUGH NO DIFFERENCE IN THE BP OR HR RESPONSES TO STRESS WERE FOUND BETWEEN CONDITIONS, SYSTOLIC BP (P=0.047) AND DIASTOLIC BP (P=0.018) RECOVERY FROM STRESS WERE SIGNIFICANTLY ACCELERATED AND SALIVARY CORTISOL REACTIVITY WAS SIGNIFICANTLY LOWER (P=0.01) IN THE YOGA CONDITION. A YOGA SESSION ALSO INCREASED SELF-CONFIDENCE (P=0.006) IN PREPARATION FOR THE TASK AND AFTER COMPLETION. MOREOVER, SELF-CONFIDENCE REPORTED AFTER THE STRESS TASK WAS CONSIDERED DEBILITATIVE TOWARDS PERFORMANCE IN THE CONTROL CONDITION, BUT REMAINED FACILITATIVE IN THE YOGA CONDITION. CONCLUSION: OUR RESULTS SHOW THAT A SINGLE VIDEO-INSTRUCTED SESSION OF HATHA YOGA WAS ABLE TO IMPROVE STRESS REACTIVITY AND RECOVERY FROM AN ACUTE STRESS TASK IN HEALTHY INDIVIDUALS. THESE POSITIVE PRELIMINARY FINDINGS ENCOURAGE FURTHER INVESTIGATION IN AT-RISK POPULATIONS IN WHICH THE MAGNITUDE OF EFFECTS MAY BE GREATER, AND SUPPORT THE USE OF YOGA FOR STRESS REACTIVITY AND RECOVERY.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
3 1875 24 REACTION TIME FOLLOWING YOGA BELLOWS-TYPE BREATHING AND BREATH AWARENESS. THE REACTION TIME (RT) WAS ASSESSED IN TWO GROUPS OF HEALTHY MALES, YOGA GROUP (M AGE = 29.0 YR.) AND NON-YOGA OR CONTROL GROUP (M AGE = 29.0 YR.), WITH 35 PARTICIPANTS EACH. THE YOGA GROUP HAD AN AVERAGE EXPERIENCE OF 6 MONTHS, WHILE THE CONTROL GROUP WAS YOGA-NAIVE. THE YOGA GROUP WAS ASSESSED IN TWO SESSIONS, (I) BHASTRIKA PRANAYAMA OR BELLOWS BREATHING AND (II) BREATH AWARENESS, WHILE THE CONTROL GROUP HAD A SINGLE CONTROL SESSION. THE TWO EXPERIMENTAL SESSIONS, ONE WITH EACH TYPE OF BREATHING, AND THE CONTROL SESSION CONSISTED OF PRE- (5 MIN.), DURING (18 MIN.), AND POST-SESSION EPOCHS (5 MIN.). ASSESSMENTS WERE MADE IN THE PRE- AND POST-SESSION EPOCHS USING A MULTI-OPERATIONAL APPARATUS FOR REACTION TIME. FOLLOWING 18 MIN. OF BHASTRIKA PRANAYAMA THERE WAS A STATISTICALLY SIGNIFICANT REDUCTION IN NUMBER OF ANTICIPATORY RESPONSES COMPARED TO BEFORE THE PRACTICE. THIS SUGGESTS THAT THE IMMEDIATE EFFECT OF BHASTRIKA PRANAYAMA IS TO INHIBIT UNNECESSARY RESPONDING TO STIMULI.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
4   33 22 A 10-WEEK YOGA PRACTICE HAS NO EFFECT ON COGNITION, BUT IMPROVES BALANCE AND MOTOR LEARNING BY ATTENUATING BRAIN-DERIVED NEUROTROPHIC FACTOR LEVELS IN OLDER ADULTS. DESPITE STUDIES INVESTIGATING THE EFFECT OF YOGA ON COGNITIVE AND MOTOR FUNCTIONING IN OLDER ADULTS, THE EFFECT ON DUAL-TASK PERFORMANCE AND MOTOR LEARNING AND THE SPECIFIC MECHANISMS UNDERLYING THE POSITIVE EFFECT OF YOGA REMAIN UNCLEAR. THUS, THE AIM OF THIS STUDY WAS TO INVESTIGATE THE EFFECTS OF YOGA ON COGNITION, BALANCE UNDER SINGLE- AND DUAL-TASK CONDITIONS, AND MOTOR LEARNING. THE POTENTIAL ROLE OF BRAIN-DERIVED NEUROTROPHIC FACTOR (BDNF) IN INDUCED IMPROVEMENT WAS ALSO EXPLORED. PARTICIPANTS AGED 60-79YEARS WERE RANDOMIZED TO EITHER A CONTROL GROUP (N=15) OR A YOGA GROUP (N=18) FOR A 10-WEEK PERIOD. THE YOGA GROUP RECEIVED 90-MIN DURATION YOGA CLASSES TWO TIMES PER WEEK. CHANGES IN COGNITION, BALANCE UNDER SINGLE- AND DUAL-TASK CONDITIONS, AND LEARNING FAST AND ACCURATE REACHING MOVEMENTS WERE ASSESSED. YOGA PRACTICE DECREASED (P<0.05) THE VELOCITY VECTOR OF THE CENTER OF PRESSURE UNDER SINGLE- AND DUAL-TASK CONDITIONS, WHEREAS NO CHANGES IN COGNITIVE PERFORMANCE WERE OBSERVED. ALTHOUGH REACTION AND MOVEMENT TIMES DURING LEARNING WERE DECREASED IN BOTH GROUPS (P<0.05), A FASTER REACTION TIME (P<0.05) AND SHORTER MOVEMENT TIME (P<0.05) WERE OBSERVED IN THE YOGA GROUP THAN IN THE CONTROL GROUP. SIGNIFICANT MODERATE RELATIONSHIPS (P<0.05) BETWEEN CHANGES IN BDNF LEVELS AND FUNCTIONAL IMPROVEMENTS WERE OBSERVED. THUS, 10WEEKS OF YOGA PRACTICE RESULTED IN IMPROVED BALANCE AND LEARNING IN THE SPEED-ACCURACY MOTOR TASK THAT WERE MEDIATED BY INCREASED BDNF LEVELS, BUT HAD NO IMPACT ON COGNITION IN OLDER ADULTS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
5 2863 24 YOGA-BASED GUIDED RELAXATION REDUCES SYMPATHETIC ACTIVITY JUDGED FROM BASELINE LEVELS. 35 MALE VOLUNTEERS WHOSE AGES RANGED FROM 20 TO 46 YEARS WERE STUDIED IN TWO SESSIONS OF YOGA-BASED GUIDED RELAXATION AND SUPINE REST. ASSESSMENTS OF AUTONOMIC VARIABLES WERE MADE FOR 15 SUBJECTS, BEFORE, DURING, AND AFTER THE PRACTICES, WHEREAS OXYGEN CONSUMPTION AND BREATH VOLUME WERE RECORDED FOR 25 SUBJECTS BEFORE AND AFTER BOTH TYPES OF RELAXATION. A SIGNIFICANT DECREASE IN OXYGEN CONSUMPTION AND INCREASE IN BREATH VOLUME WERE RECORDED AFTER GUIDED RELAXATION (PAIRED T TEST). THERE WERE COMPARABLE REDUCTIONS IN HEART RATE AND SKIN CONDUCTANCE DURING BOTH TYPES OF RELAXATION. DURING GUIDED RELAXATION THE POWER OF THE LOW FREQUENCY COMPONENT OF THE HEART-RATE VARIABILITY SPECTRUM REDUCED, WHEREAS THE POWER OF THE HIGH FREQUENCY COMPONENT INCREASED, SUGGESTING REDUCED SYMPATHETIC ACTIVITY. ALSO, SUBJECTS WITH A BASELINE RATIO OF LF/HF > 0.5 SHOWED A SIGNIFICANT DECREASE IN THE RATIO AFTER GUIDED RELAXATION, WHILE SUBJECTS WITH A RATIO < OR = 0.5 AT BASELINE SHOWED NO SUCH CHANGE. THE RESULTS SUGGEST THAT SYMPATHETIC ACTIVITY DECREASED AFTER GUIDED RELAXATION BASED ON YOGA, DEPENDING ON THE BASELINE LEVELS.	2002	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
6  462 27 CHANGES IN REACTION TIME AFTER YOGA BELLOWS-TYPE BREATHING IN HEALTHY FEMALE VOLUNTEERS. BACKGROUND: PREVIOUSLY, YOGA BELLOWS-TYPE BREATHING (BHASTRIKA PRANAYAMA) REDUCED REACTION TIME (RT) OR REDUCED ANTICIPATORY RESPONSES IN MALE PARTICIPANTS OR A MIXED GROUP OF MALE AND FEMALE PARTICIPANTS. AIMS: THE PRESENT STUDY AS A CONTROL TRIAL AIMED TO ASSESS THE EFFECTS OF YOGA BELLOWS-TYPE BREATHING ON RT IN FEMALES EXCLUSIVELY. METHODS: THE SAMPLE CONSISTED OF 25 HEALTHY FEMALES, AGED BETWEEN 19 AND 32 YEARS (GROUP MEAN +/- STANDARD DEVIATION, 22.8 +/- 3.5 YEARS). ALL OF THEM HAD PRIOR MINIMUM EXPERIENCE OF YOGA INCLUDING YOGA BELLOWS-TYPE BREATHING OF 12 MONTHS. THE RT WAS ASSESSED IN EACH PARTICIPANT BEFORE AND AFTER THREE RANDOMIZED SESSIONS DIFFERED IN THE INTERVENTION GIVEN HELD ON THREE SEPARATE DAYS. THE SESSIONS WERE (I) YOGA BELLOWS-TYPE BREATHING OR BHASTRIKA PRANAYAMA(BHK), (II) BREATH AWARENESS (BAW), AND (III) SITTING QUIETLY (CTL) AS A CONTROL SESSION. THE DURATION OF THE INTERVENTION WAS 18 MIN, AND THE PARTICIPANTS WERE ASSESSED FOR RT BEFORE AND AFTER THE INTERVENTION. RESULTS: REPEATED MEASURES ANOVA, POST HOC TESTS WITH BONFERRONI ADJUSTED SHOWED THAT THE TIME TAKEN TO OBTAIN A CORRECT RESPONSE REDUCED SIGNIFICANTLY AFTER 18 MIN OF BAW (P < 0.05) AND CTL (P < 0.05). HOWEVER, NO CHANGES WERE SEEN IN THE RT AFTER BHK. CONCLUSIONS: THE RESULTS SUGGEST THAT DIFFERENT INTERVENTIONS MAY OPTIMIZE PERFORMANCE IN TASKS REQUIRING ATTENTION IN FEMALES COMPARED TO MALES.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
7  809 39 EFFECT OF YOGA ON AUTONOMIC FUNCTIONS AND PSYCHOLOGICAL STATUS DURING BOTH PHASES OF MENSTRUAL CYCLE IN YOUNG HEALTHY FEMALES. CONTEXT: PREMENSTRUAL STRESS AFFECTS 75% OF WOMEN OF CHILDBEARING AGE AND YOGA HAS BEEN FOUND TO BE BENEFICIAL IN MANY PSYCHO-SOMATIC DISORDERS. AIMS: TO INVESTIGATE THE EFFECT OF INTEGRATED YOGA ON AUTONOMIC PARAMETERS AND PSYCHOLOGICAL WELL-BEING DURING BOTH PRE AND POST PHASES OF MENSTRUAL CYCLE IN HEALTHY YOUNG FEMALE SUBJECTS. SETTINGS AND DESIGN: PRESENT STUDY IS A RANDOMIZED CONTROL TRIAL AND WAS CONDUCTED IN THE DEPARTMENT OF PHYSIOLOGY, LADY HARDINGE MEDICAL COLLEGE, NEW DELHI, INDIA. MATERIAL AND METHODS: FIFTY APPARENTLY HEALTHY FEMALES IN THE AGE GROUP OF 18-20 YEARS WERE RANDOMIZED INTO TWO GROUPS: GROUP I (N=25) CONSISTED OF SUBJECTS WHO PRACTICED YOGA 35-40 MINUTES PER DAY, SIX TIMES PER WEEK FOR THE DURATION OF THREE MENSTRUAL CYCLES. TRAINING WAS GIVEN BY QUALIFIED YOGA INSTRUCTOR. GROUP II (N=25) SUBJECTS ACTED AS CONTROLS. FOLLOWING PARAMETERS WERE RECORDED AT THE BEGINNING AND AFTER COMPLETION OF THREE MENSTRUAL CYCLES IN ALL THE SUBJECTS: HEIGHT, WEIGHT (BW), RESTING HEART RATE (HR), RESTING SYSTOLIC (SBP) AND DIASTOLIC BLOOD PRESSURE (DBP), PARASYMPATHETIC REACTIVITY TESTS INCLUDING EXPIRATION-INSPIRATION RATIO (E: I RATIO) AND 30:15 RATIO, SYMPATHETIC REACTIVITY TESTS INCLUDING BP CHANGES DUE TO ISOMETRIC HAND GRIP (IHG) EXERCISE, AND COLD PRESSOR TEST (CPT). ASSESSMENT OF PSYCHOLOGICAL STATUS WAS DONE BY ADMINISTERING DIPAS (DEFENSE INSTITUTE OF PHYSIOLOGY AND ALLIED SCIENCES) INVENTORIES OF ANGER SELF REPORT SCALE, TRAIT ANXIETY, SENSE OF WELL-BEING AND DEPRESSION SCALE. STATISTICAL ANALYSIS: INTRA-GROUP COMPARISON OF PHYSIOLOGICAL PARAMETERS WAS DONE BY USING PAIRED 'T' TEST, WHEREAS INTRA-GROUP COMPARISON OF NON-PARAMETERIC DATA SUCH AS SCORES OF ANXIETY, DEPRESSION, ANGER AND SENSE OF WELL-BEING WAS DONE BY WILCOXON SIGNED-RANK TEST. INTER-GROUP COMPARISON OF PARAMETERS WAS DONE BY STUDENTS 'T' TEST FOR PARAMETRIC TESTS AND MANN-WHITNEY 'U' TEST FOR NON-PARAMETERIC TESTS. RESULTS: THERE WAS SIGNIFICANTLY HIGHER BW, RESTING SBP, DBP, SYMPATHETIC ACTIVITY AND BLUNTING OF PARASYMPATHETIC REACTIVITY AND ALSO, SIGNIFICANTLY HIGHER SCORES OF ANGER, DEPRESSION, ANXIETY AND DECREASED SCORE OF WELL-BEING IN PREMENSTRUAL PHASE AS COMPARED TO POSTMENSTRUAL PHASE IN BOTH THE GROUPS IN INITIAL CYCLE. THERE WAS SIGNIFICANTLY HIGHER PERCENTAGE DECREASE IN BW, HR, SBP & DBP IN YOGA GROUP AS COMPARED TO CONTROL GROUP IN BOTH THE PHASES FROM INITIAL TO SECOND AND ONWARDS BETWEEN SECOND AND THIRD MENSTRUAL CYCLE. ALSO, DECREASE IN ANGER, DEPRESSION AND ANXIETY AND INCREASE IN WELL-BEING SCORE WAS SIGNIFICANT IN YOGA GROUP AS COMPARED TO CONTROL GROUP FROM INITIAL TO SECOND AND THIRD CYCLE IN PREMENSTRUAL PHASE WHILE THE CHANGE WAS SIGNIFICANT ONLY IN DEPRESSION SCORE IN POSTMENSTRUAL PHASE. CONCLUSION: OUR STUDY SHOWS THAT THERE WAS SIGNIFICANT ALTERATION OF AUTONOMIC FUNCTIONS AND PSYCHOLOGICAL STATUS IN PREMENSTRUAL PHASE WHEN COMPARED WITH POSTMENSTRUAL PHASE IN YOUNG HEALTHY FEMALES. ALSO, REGULAR PRACTICE OF YOGA HAS BENEFICIAL EFFECTS ON BOTH PHASES OF MENSTRUAL CYCLE BY BRINGING PARASYMPATHODOMINANCE AND PSYCHOLOGICAL WELL-BEING PROBABLY BY BALANCING NEURO-ENDOCRINAL AXIS.	2013	

8  306 26 AN EVALUATION OF THE ABILITY TO VOLUNTARILY REDUCE THE HEART RATE AFTER A MONTH OF YOGA PRACTICE. THE STUDY AIMED AT DETERMINING WHETHER NOVICES TO YOGA WOULD BE ABLE TO REDUCE THEIR HEART RATE VOLUNTARILY AND WHETHER THE MAGNITUDE OF REDUCTION WOULD BE MORE AFTER 30 DAYS OF YOGA TRAINING. TWO GROUPS (YOGA AND CONTROL, N = 12 EACH) WERE ASSESSED ON DAY 1 AND ON DAY 30. DURING THE INTERVENING 30 DAYS, THE YOGA GROUP RECEIVED TRAINING IN YOGA TECHNIQUES WHILE THE CONTROL GROUP CARRIED ON WITH THEIR ROUTINE. AT EACH ASSESSMENT THE BASELINE HEART RATE WAS RECORDED FOR ONE MINUTE, THIS WAS FOLLOWED BY A SIX-MINUTE PERIOD DURING WHICH PARTICIPANTS WERE ASKED TO ATTEMPT TO VOLUNTARILY REDUCE THEIR HEART RATE, USING ANY STRATEGY. BOTH THE BASELINE HEART RATE AND THE LOWEST HEART RATE ACHIEVED VOLUNTARILY DURING THE SIX-MINUTE PERIOD WERE SIGNIFICANTLY LOWER IN THE YOGA GROUP ON DAY 30 COMPARED TO DAY 1 BY A GROUP AVERAGE OF 10.7 BEATS PER MINUTE (I.E., BPM) AND 6.8 BPM, RESPECTIVELY (P < .05, WILCOXON PAIRED SIGNED RANKS TEST). IN CONTRAST, THERE WAS NO SIGNIFICANT CHANGE IN EITHER THE BASELINE HEART RATE OR THE LOWEST HEART RATE ACHIEVED VOLUNTARILY IN THE CONTROL GROUP ON DAY 30 COMPARED TO DAY 1. THE RESULTS SUGGEST THAT YOGA TRAINING CAN ENABLE PRACTITIONERS TO USE THEIR OWN STRATEGIES TO REDUCE THE HEART RATE, WHICH HAS POSSIBLE THERAPEUTIC APPLICATIONS.	2004	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
9  941 24 EFFECTS OF 8 WEEKS OF MODIFIED HATHA YOGA TRAINING ON RESTING-STATE BRAIN ACTIVITY AND THE P300 ERP IN PATIENTS WITH PHYSICAL DISABILITY-RELATED STRESS. [PURPOSE] WE EXAMINED THE EFFECTS OF HATHA YOGA ON EEG AND ERP IN PATIENTS WITH PHYSICAL DISABILITY-RELATED STRESS. [PARTICIPANTS AND METHODS] EIGHTEEN MALE AND FEMALE INJURED WORKERS WITH HIGH STRESS LEVELS, AGED BETWEEN 18 TO 55 YEARS, WERE EVENLY DIVIDED INTO TWO GROUPS: UNTRAINED (CG) AND TRAINED (TG) MODIFIED HATHA YOGA GROUPS. A MODIFIED HATHA YOGA PROTOCOL WAS DESIGNED FOR THIS POPULATION BY TWO CERTIFIED YOGA INSTRUCTORS, APPROVED BY A PHYSICAL THERAPIST, AND CONDUCTED FOR ONE HOUR, THREE TIMES WEEKLY FOR 8 WEEKS. [RESULTS] THE RESULTS INDICATED A SIGNIFICANT INCREASE IN ALPHA EEG ACTIVITY OVER THE FRONTAL, CENTRAL, AND PARIETAL ELECTRODES AND THE DELTA EEG ACTIVITY OVER THE CENTROPARIETAL ELECTRODE FROM PRE- TO POST-TRAINING IN TG. IN ADDITION, SIGNIFICANTLY FASTER AUDITORY REACTION TIME FOR TARGET STIMULI, AS WELL AS LOWER P300 PEAK LATENCY OF ERP IN AUDITORY ODDBALL PARADIGM WERE OBTAINED IN TG AFTER 8 WEEKS OF YOGA TRAINING COMPARE TO CG. [CONCLUSION] CHANGES IN BRAIN ACTIVITY AND ERP COMPONENTS FOLLOWING YOGA TRAINING WOULD SUPPORT THE PSYCHOPHYSIOLOGICAL EFFECTS OF HATHA YOGA AS AN ADJUNCT TO ROUTINE REHABILITATION.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
10 2138 24 THE EFFECTS OF AN 8-WEEK HATHA YOGA INTERVENTION ON EXECUTIVE FUNCTION IN OLDER ADULTS. BACKGROUND: FEW SCIENTIFIC STUDIES HAVE EXAMINED MOVEMENT-BASED EMBODIED CONTEMPLATIVE PRACTICES SUCH AS YOGA AND THEIR EFFECTS ON COGNITION. THE PURPOSE OF THIS RANDOMIZED CONTROLLED TRIAL WAS TO EXAMINE THE EFFECTS OF AN 8-WEEK HATHA YOGA INTERVENTION ON EXECUTIVE FUNCTION MEASURES OF TASK SWITCHING AND WORKING MEMORY CAPACITY. METHODS: COMMUNITY-DWELLING OLDER ADULTS (N = 118; MEAN AGE = 62.0) WERE RANDOMIZED TO ONE OF TWO GROUPS: A HATHA YOGA INTERVENTION OR A STRETCHING-STRENGTHENING CONTROL. BOTH GROUPS PARTICIPATED IN HOUR-LONG EXERCISE CLASSES 3X/WEEK OVER THE 8-WEEK STUDY PERIOD. ALL PARTICIPANTS COMPLETED ESTABLISHED TESTS OF EXECUTIVE FUNCTION INCLUDING THE TASK SWITCHING PARADIGM, N-BACK AND RUNNING MEMORY SPAN AT BASELINE AND FOLLOW-UP. RESULTS: ANALYSIS OF COVARIANCES SHOWED SIGNIFICANTLY SHORTER REACTION TIMES ON THE MIXED AND REPEAT TASK SWITCHING TRIALS (PARTIAL ETA(2) = .04, P < .05) FOR THE HATHA YOGA GROUP. HIGHER ACCURACY WAS RECORDED ON THE SINGLE TRIALS (PARTIAL ETA(2) = .05, P < .05), THE 2-BACK CONDITION OF THE N-BACK (PARTIAL ETA(2) = .08, P < .001), AND PARTIAL RECALL SCORES (PARTIAL ETA(2) = .06, P < .01) OF RUNNING SPAN TASK. CONCLUSIONS: FOLLOWING 8 WEEKS OF YOGA PRACTICE, PARTICIPANTS IN THE YOGA INTERVENTION GROUP SHOWED SIGNIFICANTLY IMPROVED PERFORMANCE ON THE EXECUTIVE FUNCTION MEASURES OF WORKING MEMORY CAPACITY AND EFFICIENCY OF MENTAL SET SHIFTING AND FLEXIBILITY COMPARED WITH THEIR STRETCHING-STRENGTHENING COUNTERPARTS. ALTHOUGH THE UNDERLYING MECHANISMS NEED TO BE INVESTIGATED, THESE RESULTS DEMAND LARGER SYSTEMATIC TRIALS TO THOROUGHLY EXAMINE EFFECTS OF YOGA ON EXECUTIVE FUNCTION AS WELL AS ACROSS OTHER DOMAINS OF COGNITION, AND ITS POTENTIAL TO MAINTAIN OR IMPROVE COGNITIVE FUNCTIONING IN THE AGING PROCESS.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
11 2743 25 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
12  985 31 EFFECTS OF HATHA YOGA AND OMKAR MEDITATION ON CARDIORESPIRATORY PERFORMANCE, PSYCHOLOGIC PROFILE, AND MELATONIN SECRETION. OBJECTIVES: TO EVALUATE EFFECTS OF HATHA YOGA AND OMKAR MEDITATION ON CARDIORESPIRATORY PERFORMANCE, PSYCHOLOGIC PROFILE, AND MELATONIN SECRETION. SUBJECTS AND METHODS: THIRTY HEALTHY MEN IN THE AGE GROUP OF 25-35 YEARS VOLUNTEERED FOR THE STUDY. THEY WERE RANDOMLY DIVIDED IN TWO GROUPS OF 15 EACH. GROUP 1 SUBJECTS SERVED AS CONTROLS AND PERFORMED BODY FLEXIBILITY EXERCISES FOR 40 MINUTES AND SLOW RUNNING FOR 20 MINUTES DURING MORNING HOURS AND PLAYED GAMES FOR 60 MINUTES DURING EVENING HOURS DAILY FOR 3 MONTHS. GROUP 2 SUBJECTS PRACTICED SELECTED YOGIC ASANAS (POSTURES) FOR 45 MINUTES AND PRANAYAMA FOR 15 MINUTES DURING THE MORNING, WHEREAS DURING THE EVENING HOURS THESE SUBJECTS PERFORMED PREPARATORY YOGIC POSTURES FOR 15 MINUTES, PRANAYAMA FOR 15 MINUTES, AND MEDITATION FOR 30 MINUTES DAILY, FOR 3 MONTHS. ORTHOSTATIC TOLERANCE, HEART RATE, BLOOD PRESSURE, RESPIRATORY RATE, DYNAMIC LUNG FUNCTION (SUCH AS FORCED VITAL CAPACITY, FORCED EXPIRATORY VOLUME IN 1 SECOND, FORCED EXPIRATORY VOLUME PERCENTAGE, PEAK EXPIRATORY FLOW RATE, AND MAXIMUM VOLUNTARY VENTILATION), AND PSYCHOLOGIC PROFILE WERE MEASURED BEFORE AND AFTER 3 MONTHS OF YOGIC PRACTICES. SERIAL BLOOD SAMPLES WERE DRAWN AT VARIOUS TIME INTERVALS TO STUDY EFFECTS OF THESE YOGIC PRACTICES AND OMKAR MEDITATION ON MELATONIN LEVELS. RESULTS: YOGIC PRACTICES FOR 3 MONTHS RESULTED IN AN IMPROVEMENT IN CARDIORESPIRATORY PERFORMANCE AND PSYCHOLOGIC PROFILE. THE PLASMA MELATONIN ALSO SHOWED AN INCREASE AFTER THREE MONTHS OF YOGIC PRACTICES. THE SYSTOLIC BLOOD PRESSURE, DIASTOLIC BLOOD PRESSURE, MEAN ARTERIAL PRESSURE, AND ORTHOSTATIC TOLERANCE DID NOT SHOW ANY SIGNIFICANT CORRELATION WITH PLASMA MELATONIN. HOWEVER, THE MAXIMUM NIGHT TIME MELATONIN LEVELS IN YOGA GROUP SHOWED A SIGNIFICANT CORRELATION (R = 0.71, P < 0.05) WITH WELL-BEING SCORE. CONCLUSION: THESE OBSERVATIONS SUGGEST THAT YOGIC PRACTICES CAN BE USED AS PSYCHOPHYSIOLOGIC STIMULI TO INCREASE ENDOGENOUS SECRETION OF MELATONIN, WHICH, IN TURN, MIGHT BE RESPONSIBLE FOR IMPROVED SENSE OF WELL-BEING.	2004	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
13  298 21 ALTERNATE-NOSTRIL YOGA BREATHING REDUCED BLOOD PRESSURE WHILE INCREASING PERFORMANCE IN A VIGILANCE TEST. BACKGROUND REPORTS SUGGEST THAT VIGILANCE OR SUSTAINED ATTENTION INCREASES SYMPATHETIC ACTIVITY. A PERSISTENT INCREASE IN SYMPATHETIC ACTIVITY CAN LEAD TO AN INCREASE IN BLOOD PRESSURE. ALTERNATE-NOSTRIL YOGA BREATHING HAS BEEN SHOWN TO BE USEFUL TO (I) IMPROVE ATTENTION AND (II) DECREASE THE SYSTOLIC AND DIASTOLIC BLOOD PRESSURE. EARLIER STUDIES DID NOT REPORT SIMULTANEOUS RECORDINGS OF THE BLOOD PRESSURE AND PERFORMANCE IN VIGILANCE TESTS AFTER ALTERNATE-NOSTRIL YOGA BREATHING. WITH THIS BACKGROUND, THE PRESENT STUDY WAS PLANNED TO DETERMINE IF 15 MINUTES OF ALTERNATE NOSTRIL YOGA BREATHING COULD IMPROVE THE PERFORMANCE IN A VIGILANCE TEST WITHOUT AN INCREASE IN BLOOD PRESSURE. MATERIAL AND METHODS FIFTEEN HEALTHY MALE VOLUNTEERS PARTICIPATED IN THE STUDY (GROUP MEAN AGE +/-SD, 22.4+/-2.4 YEARS). PARTICIPANTS WERE ASSESSED ON 3 SEPARATE DAYS IN 3 DIFFERENT SESSIONS. THESE WERE (I) ALTERNATE NOSTRIL YOGA BREATHING, (II) BREATH AWARENESS, AND (III) SITTING QUIETLY AS A CONTROL. BLOOD PRESSURE AND THE DIGIT VIGILANCE TEST WERE SIMULTANEOUSLY ASSESSED BEFORE AND AFTER EACH SESSION. RESULTS SYSTOLIC BLOOD PRESSURE (P<0.01), MEAN ARTERIAL BLOOD PRESSURE (P<0.05), AND THE TIME TAKEN TO COMPLETE THE DIGIT VIGILANCE TEST (P<0.05) SIGNIFICANTLY DECREASED FOLLOWING ALTERNATE-NOSTRIL YOGA BREATHING. THE TIME TAKEN TO COMPLETE THE DIGIT VIGILANCE TEST DIFFERED SIGNIFICANTLY BETWEEN SESSIONS (P<0.05). THE TIME TAKEN TO COMPLETE THE DIGIT VIGILANCE TEST WAS ALSO SIGNIFICANTLY DECREASED AFTER SITTING QUIETLY (P<0.01). CONCLUSIONS ALTERNATE-NOSTRIL YOGA BREATHING APPEARS TO IMPROVE PERFORMANCE IN THE DIGIT VIGILANCE TEST, ALONG WITH A REDUCTION IN SYSTOLIC BLOOD PRESSURE. THIS IS SUGGESTIVE OF BETTER VIGILANCE WITHOUT SYMPATHETIC ACTIVATION.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
14  864 25 EFFECT OF YOGA PRACTICES ON PSYCHO-MOTOR ABILITIES AMONG INTELLECTUALLY DISABLED CHILDREN. THE CHILDREN WITH INTELLECTUAL DISABILITIES SHOW DISORDERS AT MOTOR DEVELOPMENT AND COORDINATION. HENCE, THE OBJECTIVE OF THIS STUDY WAS TO SEE THE EFFECT OF YOGA PRACTICES ON PSYCHO-MOTOR ABILITIES OF INTELLECTUALLY DISABLED CHILDREN. SEVENTY INTELLECTUALLY DISABLED CHILDREN WERE DIVIDED INTO EXPERIMENTAL GROUP AND CONTROL GROUP. BOTH EXPERIMENTAL AND CONTROL GROUP WERE ASSESSED ON THE FIRST DAY AND AFTER 12 WEEKS OF THE YOGA INTERVENTION FOR STATIC BALANCE, EYE HAND COORDINATION, AGILITY AND REACTION TIME. THE SUBJECTS OF EXPERIMENTAL GROUP THEN UNDERWENT A TRAINING OF YOGA PRACTICES, FOR 1 HR FOR A TOTAL PERIOD OF 12 WEEKS. THE RESULT OF WITHIN GROUP COMPARISON REVEALED SIGNIFICANT IMPROVEMENT IN STATIC BALANCE, EYE HAND COORDINATION, AGILITY, AND REACTION TIME (P< 0.001) IN SUBJECTS OF YOGA GROUP HOWEVER NO CHANGE WAS OBSERVED IN CONTROL GROUP. THE PRESENT STUDY DEMONSTRATED THAT 12 WEEKS OF YOGA IS EFFECTIVE IN IMPROVING PSYCHO-MOTOR ABILITIES OF INTELLECTUALLY DISABLED CHILDREN.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
15  297 25 ALTERNATE NOSTRIL BREATHING AT DIFFERENT RATES AND ITS INFLUENCE ON HEART RATE VARIABILITY IN NON PRACTITIONERS OF YOGA. INTRODUCTION: HEART RATE VARIABILITY IS A MEASURE OF MODULATION IN AUTONOMIC INPUT TO THE HEART AND IS ONE OF THE MARKERS OF AUTONOMIC FUNCTIONS. THOUGH THERE ARE MANY STUDIES ON THE LONG TERM INFLUENCE OF BREATHING ON HRV (HEART RATE VARIABILITY) THERE ARE ONLY A FEW STUDIES ON THE IMMEDIATE EFFECT OF BREATHING ESPECIALLY ALTERNATE NOSTRIL BREATHING ON HRV. THIS STUDY FOCUSES ON THE IMMEDIATE EFFECTS OF ALTERNATE NOSTRIL BREATHING AND THE INFLUENCE OF DIFFERENT BREATHING RATES ON HRV. MATERIALS AND METHODS: THE STUDY WAS DONE ON 25 SUBJECTS IN THE AGE GROUP OF 17-35 YEARS. ECG AND RESPIRATION WERE RECORDED BEFORE INTERVENTION AND IMMEDIATELY AFTER THE SUBJECTS WERE ASKED TO PERFORM ALTERNATE NOSTRIL BREATHING FOR FIVE MINUTES. RESULTS: LOW FREQUENCY (LF) WHICH IS A MARKER OF SYMPATHETIC ACTIVITY INCREASED, HIGH FREQUENCY (HF) WHICH IS A MARKER OF PARASYMPATHETIC ACTIVITY DECREASED AND THEIR RATIO LF/HF WHICH IS A MARKER OF SYMPATHO/VAGAL BALANCE INCREASED IMMEDIATELY AFTER 6 AND 12 MINUTES IN COMPARISON TO BASELINE VALUES WHEREAS THERE WAS NO SIGNIFICANT DIFFERENCE IN THE MEANS OF THESE COMPONENTS WHEN BOTH 6 AND 12 MINUTES WERE COMPARED. CONCLUSION: IMMEDIATE EFFECTS OF ALTERNATE NOSTRIL BREATHING ON HRV IN NON PRACTITIONERS OF YOGIC BREATHING ARE VERY DIFFERENT FROM THE LONG TERM INFLUENCE OF YOGIC BREATHING ON HRV WHICH SHOW A PREDOMINANT PARASYMPATHETIC INFLUENCE ON THE HEART.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
16  629 19 DIFFERENCES IN BRAIN STRUCTURE AND FUNCTION AMONG YOGA PRACTITIONERS AND CONTROLS. BACKGROUND: YOGA IS A MIND-BODY BASED PHYSICAL ACTIVITY THAT HAS DEMONSTRATED A VARIETY OF PHYSIOLOGICAL, PSYCHOLOGICAL AND COGNITIVE HEALTH BENEFITS. ALTHOUGH YOGA PRACTICE HAS SHOWN TO IMPROVE COGNITIVE PERFORMANCE, FEW STUDIES HAVE EXAMINED THE UNDERLYING NEUROLOGICAL CORRELATES. OBJECTIVE: THE CURRENT STUDY AIMED TO DETERMINE THE DIFFERENCES IN GRAY MATTER VOLUME OF THE HIPPOCAMPUS, THALAMUS AND CAUDATE NUCLEUS AND BRAIN ACTIVATION DURING THE STERNBERG WORKING MEMORY TASK. METHOD: PARTICIPANTS WERE 13 EXPERIENCED YOGA PRACTITIONERS (MEAN AGE = 35.8), DEFINED AS HAVING MORE THAN 3 YEARS OF REGULAR YOGA PRACTICE, AND 13 AGE- AND SEX-MATCHED CONTROLS (MEAN AGE = 35.7). ALL PARTICIPANTS COMPLETED A 6-MIN WALK TEST TO ASSESS FITNESS, PSYCHOSOCIAL AND DEMOGRAPHIC QUESTIONNAIRES; AND UNDERWENT MAGNETIC RESONANCE IMAGING TO ASSESS GRAY MATTER VOLUME AND BRAIN ACTIVATION. RESULTS: THERE WERE NO GROUP DIFFERENCES ON DEMOGRAPHIC MEASURES OF INCOME, EDUCATION AND ON ESTIMATED VO2MAX OR PHYSICAL ACTIVITY LEVELS. GRAY MATTER VOLUME DIFFERENCES WERE OBSERVED IN THE LEFT HIPPOCAMPUS, SHOWING GREATER VOLUME IN EXPERIENCED YOGA PRACTITIONERS COMPARED TO CONTROLS (P = 0.017). THE FUNCTIONAL MRI RESULTS REVEALED LESS ACTIVATION IN THE DORSOLATERAL PREFRONTAL CORTEX IN YOGA PRACTITIONERS COMPARED TO CONTROLS DURING THE ENCODING PHASE OF THE STERNBERG TASK (P < 0.05). REACTION TIME AND ACCURACY ON THE TASK DID NOT DIFFER BETWEEN THE GROUPS. CONCLUSIONS: OUR RESULTS SUGGEST AN ASSOCIATION BETWEEN REGULAR LONG-TERM YOGA PRACTICE AND DIFFERENTIAL STRUCTURE AND FUNCTION OF SPECIFIC BRAIN REGIONS INVOLVED IN EXECUTIVE FUNCTION, SPECIFICALLY WORKING MEMORY, WHICH HAS PREVIOUSLY SHOWN TO IMPROVE WITH YOGA PRACTICE. FUTURE STUDIES NEED TO EXAMINE INTERVENTION EFFECTS OF YOGA AND EXPLORE ITS POTENTIAL TO MAINTAIN AND IMPROVE COGNITIVE HEALTH ACROSS THE LIFESPAN THROUGH LONGITUDINAL AND INTERVENTION STUDIES.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
17  523 26 COMPARISON OF CHANGES IN AUTONOMIC AND RESPIRATORY PARAMETERS OF GIRLS AFTER YOGA AND GAMES AT A COMMUNITY HOME. THE HEART RATE, BREATHING RATE, AND SKIN RESISTANCE WERE RECORDED FOR 20 COMMUNITY HOME GIRLS (HOME GROUP) AND FOR 20 AGE-MATCHED GIRLS FROM A REGULAR SCHOOL (SCHOOL GROUP). THE FORMER GROUP HAD A SIGNIFICANTLY HIGHER RATE OF BREATHING AND A MORE IRREGULAR BREATH PATTERN KNOWN TO CORRELATE WITH HIGH FEAR AND ANXIETY, THAN THE SCHOOL GROUP. SKIN RESISTANCE WAS SIGNIFICANTLY LOWER IN THE SCHOOL GROUP, WHICH MAY SUGGEST GREATER AROUSAL, 28 GIRLS OF THE HOME GROUP FORMED 14 PAIRS, MATCHED FOR AGE AND DURATION OF STAY IN THE HOME. SUBJECTS OF A PAIR WERE RANDOMLY ASSIGNED TO EITHER YOGA OR GAMES GROUPS. FOR THE FORMER EMPHASIS WAS ON RELAXATION AND AWARENESS, WHEREAS FOR THE LATTER INCREASING PHYSICAL ACTIVITY WAS EMPHASIZED. AT THE END OF AN HOUR DAILY FOR SIX MONTHS BOTH GROUPS SHOWED A SIGNIFICANT DECREASE IN THE RESTING HEART RATE RELATIVE TO INITIAL VALUES (WILCOXON PAIRED-SAMPLE REST), AND THE YOGA GROUP SHOWED A SIGNIFICANT DECREASE IN BREATH RATE, WHICH APPEARED MORE REGULAR BUT NO SIGNIFICANT INCREASE IN THE SKIN RESISTANCE. THESE RESULTS SUGGEST THAT A YOGA PROGRAM WHICH INCLUDES RELAXATION, AWARENESS, AND GRADED PHYSICAL ACTIVITY IS A USEFUL ADDITION TO THE ROUTINE OF COMMUNITY HOME CHILDREN.	1997	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
18  300 24 AN ASSESSMENT OF A SEQUENCE OF YOGA EXERCISES TO PATIENTS WITH ARTERIAL HYPERTENSION. THIS QUASI-EXPERIMENTAL STUDY DESCRIBES THE EFFECTS OF A YOGA SEQUENCE FOLLOWING HEMODYNAMIC AND BIOCHEMICAL PARAMETERS IN PATIENTS WITH HYPERTENSION. THIRTY-THREE VOLUNTEERS PARTICIPATED IN THE STUDY (CONTROL = 16 AND YOGA = 17) FOR FOUR MONTHS. BLOOD PRESSURE MEASUREMENTS, CARDIAC AND RESPIRATORY RATE WERE COLLECTED MONTHLY, WHILE THE BIOCHEMICAL PROFILE WAS TAKEN AT THE BEGINNING AND END OF THE PROGRAM. TO ANALYZE THE DATA, STUDENT'S T TEST AND REPEATED MEASURES ANALYSES WERE PERFORMED. THE YOGA GROUP SHOWED A SIGNIFICANT REDUCTION OF SYSTOLIC BLOOD PRESSURE, HEART AND RESPIRATORY RATE (P < 0.05). AS FOR THE BIOCHEMICAL PROFILE, THE YOGA GROUP SHOWED CORRELATION COEFFICIENTS BETWEEN INITIAL VALUES AND FINAL RESPONSES GREATER THAN THE CONTROL OF FASTING GLUCOSE, TOTAL CHOLESTEROL, LDL-CHOLESTEROL AND TRIGLYCERIDES. THE ELABORATED SEQUENCE PRACTICE PROMOTED SIGNIFICANT CARDIOVASCULAR AND METABOLIC BENEFITS.

19 2364 23 VOLUNTARY HEART RATE REDUCTION FOLLOWING YOGA USING DIFFERENT STRATEGIES. BACKGROUND/AIMS: ONE MONTH OF YOGA TRAINING HAS BEEN SHOWN TO REDUCE THE PULSE RATE VOLUNTARILY WITHOUT USING EXTERNAL CUES. HENCE, THE PRESENT STUDY WAS DESIGNED TO UNDERSTAND THE STRATEGIES USED BY YOGA PRACTITIONERS AND AUTONOMIC CHANGES ASSOCIATED WITH VOLUNTARY HEART RATE REDUCTION. MATERIALS AND METHODS: FIFTY VOLUNTEERS (GROUP MEAN AGE +/- S.D., 25.4 +/- 4.8 YEARS; 25 MALES) WERE ASSESSED IN TWO TRIALS ON SEPARATE DAYS. EACH TRIAL WAS FOR 12 MINUTES, WITH A 'PRE' STATE AND 'DURING' STATE OF 6 MINUTES EACH. FOR BOTH TRIALS THE 'PRE' STATE WAS RELAXATION WITH EYES CLOSED. IN THE 'DURING' STATE OF TRIAL I, SUBJECTS WERE ASKED TO VOLUNTARILY REDUCE THEIR HEART RATE USING A STRATEGY OF THEIR CHOICE. FROM THEIR RESPONSES TO SPECIFIC QUESTIONS IT WAS DETERMINED THAT 22 OUT OF 50 PERSONS USED BREATH REGULATION AS A STRATEGY. HENCE, IN THE 'DURING' STATE OF TRIAL II, SUBJECTS WERE ASKED TO VOLUNTARILY REDUCE THEIR HEART RATE BY BREATH REGULATION. RESULTS: IN THE FIRST TRIAL, THE HEART RATE WAS REDUCED BY AN AVERAGE OF 19.6 BEATS PER MINUTE AND IN THE SECOND TRIAL (WITH BREATH REGULATION EXCLUSIVELY) AN AVERAGE DECREASE OF 22.2 BEATS PER MINUTE WAS ACHIEVED. CONCLUSIONS: HENCE, THE STRATEGY USED DID NOT MARKEDLY ALTER THE OUTCOME.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
20  859 25 EFFECT OF YOGA PRACTICE ON LEVELS OF INFLAMMATORY MARKERS AFTER MODERATE AND STRENUOUS EXERCISE. BACKGROUND AND OBJECTIVES: TO EVALUATE THE EFFECT OF YOGA PRACTICE AND EXERCISE CHALLENGE ON TUMOUR NECROSIS FACTOR ALPHA (TNF-ALPHA), INTERLEUKIN-6 (IL-6) LEVELS AND LIPID PROFILE. MATERIALS AND METHODS: TWO HUNDRED AND EIGHTEEN SUBJECTS PARTICIPATED IN THE STUDY. ONE HUNDRED AND NINE VOLUNTEERS (51 MALES AND 58 FEMALES) IN THE AGE GROUP OF 20 TO 60 YEARS, WHO PRACTICED YOGA REGULARLY FOR OVER FIVE YEARS FOR A PERIOD OF ONE HOUR DAILY, PERFORMED A BOUT OF MODERATE EXERCISE AND A BOUT OF STRENUOUS EXERCISE AS PER STANDARDIZED SHUTTLE WALK TEST PROTOCOL. ANTHROPOMETRICALLY MATCHED, AGE MATCHED AND GENDER MATCHED SUBJECTS, WHO DID NOT PRACTICE YOGA (NON-YOGA GROUP) WERE CHOSEN AS CONTROLS (NON-YOGA, N=109). THE NON-YOGA GROUP ALSO PERFORMED SIMILAR EXERCISES. THE BLOOD SAMPLES OF BOTH THE GROUPS WERE COLLECTED BEFORE AND AFTER THE EXERCISES. TNF-ALPHA AND IL-6 WAS ANALYSED BEFORE AND AFTER THE EXERCISE BY SANDWICH ELISA (ENZYME LINKED IMMUNOSORBENT ASSAY). RESULTS: RESTING PLASMA TNF-ALPHA CONCENTRATION WAS SIGNIFICANTLY HIGHER IN NON-YOGA GROUP WHEN COMPARED TO YOGA GROUP (P<0.05). THERE WAS AN INCREASE IN TNF-ALPHA LEVELS IN BOTH THE GROUPS IN RESPONSE TO STRENUOUS EXERCISE. THERE WAS NO GENDER DIFFERENCE IN TNF-ALPHA AND IL-6 LEVELS BEFORE AND AFTER EXERCISE IN YOGA AND NON-YOGA GROUPS. CONCLUSION: REGULAR PRACTICE OF YOGA LOWERS BASAL TNF-ALPHA AND IL-6 LEVELS. IT ALSO REDUCES THE EXTENT OF INCREASE OF TNF-ALPHA AND IL-6 TO A PHYSICAL CHALLENGE OF MODERATE EXERCISE AND STRENUOUS EXERCISE. THERE IS NO SIGNIFICANT GENDER DIFFERENCE IN THE TNF-ALPHA AND IL-6 LEVELS. REGULAR PRACTICE OF YOGA CAN PROTECT THE INDIVIDUAL AGAINST INFLAMMATORY DISEASES BY FAVOURABLY ALTERING PRO-INFLAMMATORY CYTOKINE LEVELS.	2015
