1  163 164 A RANDOMIZED CONTROL TRIAL OF THE EFFECT OF YOGA ON GUNAS (PERSONALITY) AND HEALTH IN NORMAL HEALTHY VOLUNTEERS. OBJECTIVE: TO STUDY THE EFFICACY OF YOGA ON GUNA (YOGIC PERSONALITY MEASURE) AND GENERAL HEALTH IN NORMAL ADULTS. METHODS: OF THE 1228 PERSONS WHO ATTENDED INTRODUCTORY LECTURES, 226 SUBJECTS AGED 18-71 YEARS, OF BOTH SEXES, WHO SATISFIED THE INCLUSION AND EXCLUSION CRITERIA AND WHO CONSENTED TO PARTICIPATE IN THE STUDY WERE RANDOMLY ALLOCATED INTO TWO GROUPS. THE YOGA(Y) GROUP PRACTISED AN INTEGRATED YOGA MODULE THAT INCLUDED ASANAS, PRANAYAMA, MEDITATION, NOTIONAL CORRECTION AND DEVOTIONAL SESSIONS. THE CONTROL GROUP PRACTISED MILD TO MODERATE PHYSICAL EXERCISES (PE). BOTH GROUPS HAD SUPERVISED PRACTICE SESSIONS (BY TRAINED EXPERTS) FOR ONE HOUR DAILY, SIX DAYS A WEEK FOR EIGHT WEEKS. GUNA (YOGIC PERSONALITY) WAS ASSESSED BEFORE AND AFTER EIGHT WEEKS USING THE SELF-ADMINISTERED VEDIC PERSONALITY INVENTORY (VPI) WHICH ASSESSES SATTVA (GENTLE AND CONTROLLED), RAJAS (VIOLENT AND UNCONTROLLED) AND TAMAS (DULL AND UNCONTROLLED). THE GENERAL HEALTH STATUS (TOTAL HEALTH), WHICH INCLUDES FOUR DOMAINS NAMELY SOMATIC SYMPTOMS (SS), ANXIETY AND INSOMNIA (AI), SOCIAL DYSFUNCTION (SF) AND SEVERE DEPRESSION (SP), WAS ASSESSED USING A GENERAL HEALTH QUESTIONNAIRE (GHQ). RESULTS: BASELINE SCORES FOR ALL THE DOMAINS FOR BOTH THE GROUPS DID NOT DIFFER SIGNIFICANTLY (P > 0.05, INDEPENDENT SAMPLES T TEST). SATTVA SHOWED A SIGNIFICANT DIFFERENCE WITHIN THE GROUPS AND THE EFFECT SIZE WAS MORE IN THE Y THAN IN THE PE GROUP. RAJAS SHOWED A SIGNIFICANT DECREASE WITHIN AND BETWEEN THE GROUPS WITH A HIGHER EFFECT SIZE IN THE PE GROUP. TAMAS SHOWED SIGNIFICANT REDUCTION WITHIN THE PE GROUP ONLY. THE GHQ REVEALED THAT THERE WAS SIGNIFICANT DECREASE IN SS, AI, SF AND SP IN BOTH Y AND PE GROUPS (WILCOXCON SINGED RANK T TEST). SS SHOWED A SIGNIFICANT DIFFERENCE BETWEEN THE GROUPS (MANN WHITNEY U TEST). CONCLUSIONS: THERE WAS AN IMPROVEMENT IN SATTVA IN BOTH THE YOGA AND CONTROL GROUPS WITH A TREND OF HIGHER EFFECT SIZE IN YOGA; RAJAS REDUCED IN BOTH BUT SIGNIFICANTLY BETTER IN PE THAN IN YOGA AND TAMAS REDUCED IN PE. THE GENERAL HEALTH STATUS IMPROVED IN BOTH THE YOGA AND CONTROL GROUPS.	2008	
                                                                                                                                                                                                                                                                                                      
2  164 113 A RANDOMIZED CONTROL TRIAL OF THE EFFECT OF YOGA ON GUNAS (PERSONALITY) AND SELF ESTEEM IN NORMAL HEALTHY VOLUNTEERS. BACKGROUND/AIMS: TO STUDY THE EFFICACY OF YOGA ON GUNAS (PERSONALITY) AND SELF ESTEEM IN NORMAL ADULTS THROUGH A RANDOMIZED COMPARATIVE STUDY. MATERIALS AND METHODS: OF THE 1228 PERSONS WHO ATTENDED MOTIVATIONAL LECTURES, 226 SUBJECTS AGED 18-71 YEARS, OF BOTH SEXES, WHO SATISFIED THE INCLUSION AND EXCLUSION CRITERIA, AND WHO CONSENTED TO PARTICIPATE IN THE STUDY WERE RANDOMLY ALLOCATED INTO TWO GROUPS. THE YOGA (Y) GROUP PRACTISED AN INTEGRATED YOGA MODULE THAT INCLUDED ASANAS, PRANAYAMA, MEDITATION, NOTIONAL CORRECTION, AND DEVOTIONAL SESSIONS. THE COMPARISON GROUP PRACTISED MILD TO MODERATE PHYSICAL EXERCISES (PE). BOTH GROUPS HAD SUPERVISED PRACTICES FOR ONE HOUR DAILY, SIX DAYS A WEEK, FOR EIGHT WEEKS. GUNA (PERSONALITY) WAS ASSESSED BEFORE AND AFTER EIGHT WEEKS USING THE SELF-ADMINISTERED "THE 'GITA" INVENTORY OF PERSONALITY" (GIN) TO ASSESS SATTVA, RAJAS, AND TAMAS. SELF ESTEEM IN TERMS OF COMPETENCY (COM), GLOBAL SELF ESTEEM (GSE), MORAL AND SELF ESTEEM (MSE), SOCIAL ESTEEM (SET), FAMILY SELF ESTEEM (FSE), BODY AND PHYSICAL APPEARANCE (BPA), AND THE LIE SCALE (LIS) WERE ASSESSED USING THE SELF ESTEEM QUESTIONNAIRE (SEQ). RESULTS: THE BASELINE SCORES FOR ALL DOMAINS FOR BOTH THE GROUPS DID NOT DIFFER SIGNIFICANTLY (P > 0.05 INDEPENDENT SAMPLES T-TEST). THERE WERE SIGNIFICANT PRE-POST IMPROVEMENTS IN ALL DOMAINS IN BOTH GROUPS (P < 0.001 PAIRED T-TEST). THE NUMBER OF PERSONS WHO SHOWED IMPROVEMENT IN SATTVA AND DECREASE IN TAMAS WAS SIGNIFICANT IN THE Y BUT NOT IN THE PE GROUP (MCNEMAR TEST). THE EFFECT SIZE FOR SELF ESTEEM IN THE Y GROUP IS GREATER THAN FOR THE PE GROUP IN THREE OUT OF SEVEN DOMAINS. CONCLUSIONS: THIS RANDOMIZED CONTROLLED STUDY HAS SHOWN THE INFLUENCE OF YOGA ON GUNAS AND SELF ESTEEM IN COMPARISON TO PHYSICAL EXERCISE.	2009	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
3  411  36 BLOOD PRESSURE AND HEART RATE VARIABILITY DURING YOGA-BASED ALTERNATE NOSTRIL BREATHING PRACTICE AND BREATH AWARENESS. BACKGROUND: PREVIOUS RESEARCH HAS SHOWN A REDUCTION IN BLOOD PRESSURE (BP) IMMEDIATELY AFTER THE PRACTICE OF ALTERNATE NOSTRIL YOGA BREATHING (ANYB) IN NORMAL HEALTHY MALE VOLUNTEERS AND IN HYPERTENSIVE PATIENTS OF BOTH SEXES. THE BP DURING ANYB HAS NOT BEEN RECORDED. MATERIAL/METHODS: PARTICIPANTS WERE 26 MALE VOLUNTEERS (GROUP MEAN AGE +/-SD, 23.8+/-3.5 YEARS). WE ASSESSED (1) HEART RATE VARIABILITY, (2) NON-INVASIVE ARTERIAL BP, AND (3) RESPIRATION RATE, DURING (A) ANYB AND (B) BREATH AWARENESS (BAW) SESSIONS. EACH SESSION WAS 25 MINUTES. WE PERFORMED ASSESSMENTS AT 3 TIME POINTS: PRE (5 MINUTES), DURING (15 MINUTES; FOR ANYB OR BAW) AND POST (5 MINUTES). A NAIVE-TO-YOGA CONTROL GROUP (N=15 MALES, MEAN AGE +/-SD 26.1+/-4.0 YEARS) WERE ASSESSED WHILE SEATED QUIETLY FOR 25 MINUTES. RESULTS: DURING ANYB THERE WAS A SIGNIFICANT DECREASE (REPEATED MEASURES ANOVA) IN SYSTOLIC BP AND RESPIRATION RATE; WHILE RMSSD (THE SQUARE ROOT OF THE MEAN OF THE SUM OF SQUARES OF DIFFERENCES BETWEEN ADJACENT NN INTERVALS) AND NN50 (THE NUMBER OF INTERVAL DIFFERENCES OF SUCCESSIVE NORMAL TO NORMAL INTERVALS GREATER THAN 50 MS) SIGNIFICANTLY INCREASED. DURING BAW RESPIRATION RATE DECREASED. IN CONTRAST, RESPIRATION RATE INCREASED DURING THE CONTROL STATE. ANYB AND BAW WERE SIGNIFICANTLY DIFFERENT (2-FACTOR ANOVA) IN RMSSD AND RESPIRATION RATE. BAW AND CONTROL WERE DIFFERENT WITH RESPECT TO RESPIRATION RATE. CONCLUSIONS: THE RESULTS SUGGEST THAT VAGAL ACTIVITY INCREASED DURING AND AFTER ANYB, WHICH COULD HAVE CONTRIBUTED TO THE DECREASE IN BP AND CHANGES IN THE HRV.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
4  165  99 A RANDOMIZED CONTROL TRIAL OF THE EFFECT OF YOGA ON VERBAL AGGRESSIVENESS IN NORMAL HEALTHY VOLUNTEERS. OBJECTIVE: TO STUDY THE EFFECT OF YOGA ON VERBAL AGGRESSIVENESS IN NORMAL HEALTHY ADULTS. METHODS: OF THE 1228 PERSONS WHO ATTENDED INTRODUCTORY LECTURES, 226 SUBJECTS OF BOTH SEXES WHO SATISFIED THE INCLUSION AND EXCLUSION CRITERIA AND WHO CONSENTED TO PARTICIPATE IN THE STUDY WERE RANDOMLY ALLOCATED INTO TWO GROUPS. THESE 226 SUBJECTS WERE BETWEEN THE AGES OF 17 AND 62 YEARS AND 173/226 COMPLETED THE EIGHT WEEKS OF INTERVENTION. THE YOGA (Y) GROUP PRACTISED AN INTEGRATED YOGA MODULE THAT INCLUDED ASANAS, PRANAYAMA, MEDITATION, NOTIONAL CORRECTION, AND DEVOTIONAL SESSIONS. THE CONTROL GROUP PRACTISED MILD TO MODERATE PHYSICAL EXERCISES (PE). BOTH GROUPS HAD SUPERVISED PRACTICES (BY TRAINED EXPERTS) FOR ONE HOUR DAILY, SIX DAYS A WEEK FOR EIGHT WEEKS. VERBAL AGGRESSIVENESS WAS ASSESSED BEFORE AND AFTER EIGHT WEEKS USING THE SELF-ADMINISTERED VERBAL AGGRESSIVE SCALE. RESULTS: THE BASELINE SCORE OF THE TWO GROUPS DID NOT DIFFER SIGNIFICANTLY (P = 0.66). THERE WAS A SIGNIFICANT DECREASE IN VERBAL AGGRESSIVENESS IN THE YOGA GROUP (P = 0.01 PAIRED SAMPLES T-TEST) WITH A NONSIGNIFICANT INCREASE IN THE PE GROUP. ANCOVA USING PRE- VALUES AS COVARIATES SHOWED A SIGNIFICANT DIFFERENCE BETWEEN THE GROUPS (P = 0.013). RMANOVA FOR INTERACTION BETWEEN THE SEXES OR AGE GROUPS IN CHANGE SCORES WERE NOT SIGNIFICANT. CONCLUSIONS: THIS STUDY HAS DEMONSTRATED THAT AN EIGHT WEEK INTERVENTION OF AN INTEGRATED YOGA MODULE DECREASED VERBAL AGGRESSIVENESS IN THE YOGA GROUP (IN MALES AND THOSE BELOW 25 YEARS OF AGE), WITH A NONSIGNIFICANT INCREASE IN THE PE GROUP.	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
5 1726  46 PERFORMANCE IN A CORSI BLOCK-TAPPING TASK FOLLOWING HIGH-FREQUENCY YOGA BREATHING OR BREATH AWARENESS. BACKGROUND: UNINOSTRIL YOGA BREATHING PRACTICES HAVE IMPROVED SPATIAL MEMORY SCORES. THERE HAS BEEN NO ASSESSMENT ON THE EFFECT OF HIGH-FREQUENCY YOGA BREATHING (HFYB) ON WORKING MEMORY AND SPATIAL MEMORY SCORES USING THE CORSI BLOCK-TAPPING TASK (CBTT). OBJECTIVES: THE PRESENT STUDY WAS PLANNED TO ASSESS THE IMMEDIATE EFFECTS OF HFYB AND BREATH AWARENESS (BAW) COMPARED TO A CONTROL SESSION ON PERFORMANCE IN A CBTT. METHODS: FIFTEEN PARTICIPANTS OF BOTH SEXES WITH AGES BETWEEN 18 AND 24 YEARS (GROUP MEAN AGE +/- STANDARD DEVIATION, 20.0 +/- 1.6 YEARS; 10 FEMALES) WERE RECRUITED FOR THE TRIAL FROM A UNIVERSITY IN NORTH INDIA. EACH PARTICIPANT WAS ASSESSED IN THREE SESSIONS CONDUCTED ON 3 SEPARATE DAYS AT THE SAME TIME OF THE DAY. THE THREE SESSIONS WERE (I) HFYB, (II) BAW, AND (III) QUIET SITTING (QS). THE DURATION OF THE INTERVENTION WAS 18 MIN. THE PARTICIPANTS WERE ASSESSED BEFORE AND AFTER ALL THE THREE SESSIONS. REPEATED-MEASURES-ANALYSES OF VARIANCE FOLLOWED BY POST HOC TESTS WITH BONFERRONI ADJUSTMENT WERE PERFORMED TO COMPARE DATA BEFORE AND AFTER ALL THE THREE SESSIONS. RESULTS: BAW RESULTED IN AN IMPROVEMENT IN BACKWARD TOTAL SCORES (P < 0.05) AND THE BACKWARD CORSI SPAN (P < 0.05; ONE TAILED). CONCLUSIONS: THE RESULTS SUGGEST THAT BAW IMPROVES PRIMARY WORKING MEMORY, SPATIAL MEMORY, AND SPATIAL ATTENTION. HFYB DID NOT CAUSE ANY CHANGE.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
6  703  47 EFFECT OF INTEGRAL YOGA ON PSYCHOLOGICAL AND HEALTH VARIABLES AND THEIR CORRELATIONS. OBJECTIVE: CERTAIN PSYCHOLOGICAL AND HEALTH VARIABLES ARE COMMONLY MEASURED IN INDIA. THIS STUDY EVALUATES THE EFFECTS OF INTEGRAL YOGA PRACTICES ON THESE VARIABLES AND ALSO THE CONSISTENCY OF CORRELATIONS OBSERVED BETWEEN THEM. MATERIALS AND METHODS: THE STUDY WAS A PRE-POST INTERVENTION STUDY. THE VARIABLES WERE MEASURED AT THE BEGINNING AND THE END OF A ONE-MONTH YOGA COURSE. THERE WAS NO CONTROL GROUP.THE STUDY WAS CARRIED OUT AT SWAMI VIVEKANANDA YOGA ANUSANDHANA SAMSTHANA (S-VYASA) UNIVERSITY, IN ITS RURAL CAMPUS SOUTH OF BANGALORE. BASED ON HEALTH CRITERIA, 108 SUBJECTS WERE SELECTED OUT OF 198 VOLUNTEERS TO FORM THE EXPERIMENTAL YOGA GROUP. AGES RANGED FROM 17 TO 63 YEARS. THE YOGASANAS (POSTURES), PRANAYAMA (BREATHING EXERCISES), RELAXATION TECHNIQUES, MEDITATION, CHANTING AND LECTURES WERE THE COMPONENTS OF YOGA INTERVENTION. THE VARIABLES MEASURED WERE SUSTAINED ATTENTION, EMOTIONAL INTELLIGENCE - EQ, GENERAL HEALTH - GHQ, GUNA PERSONALITY - SATTVA, RAJAS AND TAMAS. RESULTS: SIGNIFICANT PRE-POST CHANGES WERE FOUND IN ALL VARIABLES. SIGNIFICANT CORRELATIONS WERE FOUND BETWEEN THE FOLLOWING PAIRS: THE TWO SUSTAINED ATTENTION VARIABLES; EMOTIONAL INTELLIGENCE AND GENERAL HEALTH; GHQ AND TAMAS; SATTVA AND TAMAS; AND RAJAS AND TAMAS. CONCLUSION: THE STUDY SHOWS THAT THERE WERE SIGNIFICANT CHANGES IN ALL VARIABLES (P< 0.001) EXCEPT IN SATTVA. IT ALSO CONFIRMS THAT EQ AND GENERAL HEALTH VARIABLES CORRELATE SIGNIFICANTLY WITH EACH OTHER AND NEGATIVELY WITH TAMAS. EQ AND TAMAS FORM POSITIVE AND NEGATIVE PREDICTORS OF HEALTH RESPECTIVELY. SATTVA CORRELATES POSITIVELY WITH EQ SUGGESTING THAT A SATTVIC PERSONALITY INDICATES BETTER SELF-CONTROL. THIS SUGGESTS THAT, BY IMPROVING GUNA PERSONALITY, LONG-TERM YOGA PRACTICE MAY STABILIZE EQ.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
7  442  30 CEREBROVASCULAR DYNAMICS ASSOCIATED WITH YOGA BREATHING AND BREATH AWARENESS. AIMS: BREATH FREQUENCY CAN ALTER CEREBRAL BLOOD FLOW. THE STUDY AIMED TO DETERMINE BILATERAL MIDDLE CEREBRAL ARTERIAL HEMODYNAMICS IN HIGH-FREQUENCY YOGA BREATHING (HFYB) AND SLOW FREQUENCY ALTERNATE NOSTRIL YOGA BREATHING (ANYB) USING TRANSCRANIAL DOPPLER SONOGRAPHY. METHODS: HEALTHY MALE VOLUNTEERS WERE ASSESSED IN TWO SEPARATE TRIALS BEFORE, DURING, AND AFTER HFYB (2.0 HZ FOR 1 MIN, N = 16) AND ANYB (12 BREATHS PER MINUTE FOR 5 MIN, N = 22). HFYB AND ANYB WERE SEPARATELY COMPARED TO BREATH AWARENESS (BAW) AND TO CONTROL SESSIONS. STATISTICAL ANALYSIS: THE DATA WERE ANALYZED USING REPEATED-MEASURES ANOVA WITH BONFERRONI ADJUSTED POST HOC TESTS. RESULTS: DURING HFYB THERE WAS A DECREASE IN END-DIASTOLIC VELOCITY (EDV) AND MEAN FLOW VELOCITY (MFV) (P < 0.01 FOR LEFT AND P < 0.05 FOR RIGHT MIDDLE CEREBRAL ARTERIES; MCA) WITH AN INCREASE IN PULSATILITY INDEX (PI) FOR THE RIGHT MCA (P < 0.05). DURING ANYB, THERE WAS A BILATERAL DECREASE IN PEAK SYSTOLIC VELOCITY (P < 0.05 FOR LEFT AND P < 0.01 FOR RIGHT MCA), EDV (P < 0.01) AND MFV (P < 0.01 FOR LEFT AND P < 0.001 FOR RIGHT MCA) AND AN INCREASE IN PI (P < 0.01). DURING BAW OF THE TWO SESSIONS THERE WAS A DECREASE IN LATERALIZED FLOW AND END-DIASTOLIC VELOCITIES (P < 0.05) AND AN INCREASE IN PI (P < 0.05). CONCLUSIONS: CHANGES IN PEAK FLOW VELOCITIES AND PULSATILITY INDICES DURING AND AFTER HFYB, ANYB, AND BAW SUGGEST DECREASED CEREBROVASCULAR BLOOD FLOW AND INCREASED FLOW RESISTANCE BASED ON DIFFERENT MECHANISMS.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
8 1317  37 HEART RATE VARIABILITY CHANGES DURING HIGH FREQUENCY YOGA BREATHING AND BREATH AWARENESS. BACKGROUND: PRE AND POST COMPARISON AFTER ONE MINUTE OF HIGH FREQUENCY YOGA BREATHING (HFYB) SUGGESTED THAT THE HFYB MODIFIES THE AUTONOMIC STATUS BY INCREASING SYMPATHETIC MODULATION, BUT ITS EFFECT DURING THE PRACTICE WAS NOT ASSESSED. METHODS: THIRTY-EIGHT MALE VOLUNTEERS WITH GROUP AVERAGE AGE +/- S.D., 23.3 +/- 4.4 YEARS WERE EACH ASSESSED ON TWO SEPARATE DAYS IN TWO SESSIONS, (I) HFYB AND (II) BREATH AWARENESS. EACH SESSION WAS FOR 35 MINUTES, WITH 3 PERIODS, I.E., PRE (5 MINUTES), DURING HFYB OR BREATH AWARENESS (15 MINUTES) AND POST (5 MINUTES). RESULTS: THERE WAS A SIGNIFICANT DECREASE IN NN50, PNN50 AND THE MEAN RR INTERVAL DURING AND AFTER HFYB AND AFTER BREATH AWARENESS, COMPARED TO THE RESPECTIVE 'PRE' VALUES (P < 0.05) (REPEATED MEASURES ANOVA FOLLOWED BY POST-HOC ANALYSIS). THE LF POWER INCREASED AND HF POWER DECREASED DURING AND AFTER BREATH AWARENESS AND LF/HF RATIO INCREASED AFTER BREATH AWARENESS (P < 0.05). CONCLUSION: THE RESULTS SUGGEST THAT THERE WAS REDUCED PARASYMPATHETIC MODULATION DURING AND AFTER HFYB AND INCREASED SYMPATHETIC MODULATION WITH REDUCED PARASYMPATHETIC MODULATION DURING AND AFTER BREATH AWARENESS.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
9  516  49 COMPARING COGNITION, COPING SKILLS AND VEDIC PERSONALITY OF INDIVIDUALS PRACTICING YOGA, PHYSICAL EXERCISE OR SEDENTARY LIFESTYLE: A CROSS-SECTIONAL FMRI STUDY. BACKGROUND: NATURE AND INTENSITY OF PHYSICAL ACTIVITY MAY INFLUENCE COGNITION, COPING MECHANISMS AND OVERALL PERSONALITY OF AN INDIVIDUAL. THE OBJECTIVE OF THIS CROSS-SECTIONAL STUDY WAS TO COMPARE COGNITION, COPING STYLES AND VEDIC PERSONALITY AMONG INDIVIDUALS PRACTICING DIFFERENT LIFESTYLE. METHODS: THIRTY-NINE HEALTHY YOUNG ADULTS OF BOTH GENDER (27.63+/-4.04 YEARS) WERE RECRUITED AND CATEGORIZED INTO THREE GROUPS; I.E. YOGA, PHYSICAL ACTIVITY OR SEDENTARY LIFESTYLE GROUPS. PARTICIPANTS WERE ASSESSED ON COGNITION, COPING STYLES AND VEDIC PERSONALITY INVENTORY (VPI). VERBAL-N-BACK AND STROOP TASKS WERE PERFORMED USING 3 TESLA MRI SCANNER. TASK BASED CONNECTIVITY (TBC) ANALYSIS WAS DONE USING CONN TOOLBOX IN SPM. RESULTS: THERE WERE NO SIGNIFICANT DIFFERENCES IN THE COGNITIVE DOMAINS ACROSS THE GROUPS. THE PLANNING (P=0.03) AND ACCEPTANCE DOMAIN (P=0.03) OF THE BRIEF COPE SCALE SHOWED DIFFERENCE ACROSS THE GROUPS. POST-HOC ANALYSIS REVEALED THAT PLANNING AND ACCEPTANCE SCORES WERE DISTINCTLY HIGHER IN THE PHYSICAL ACTIVITY GROUP, HOWEVER, THERE WAS NO DIFFERENCE BETWEEN PHYSICAL ACTIVITY GROUP AND YOGA PRACTITIONERS. SIMILARLY, IN THE VPI, SATTVA (P=0.003), RAJAS (P=0.05) AND TAMAS (P=0.01) WERE DIFFERENT ACROSS THE GROUPS, AND THE POST HOC ANALYSIS SHOWED SUPERIORITY IN SATTVA SCORES IN YOGA GROUP, MEANWHILE, BOTH RAJAS AND TAMAS WERE HIGHER IN THE PHYSICAL ACTIVITY GROUP. YOGA PRACTITIONERS PREFERENTIALLY RECRUITED LEFT SUPERIOR FRONTAL GYRUS IN RELATION TO THE PHYSICALLY ACTIVE GROUP AND PRECUNEUS IN RELATION TO THE SEDENTARY LIFESTYLE GROUP. CONCLUSION: THE STUDY REVEALED THAT YOGA PRACTITIONERS HAD A DISTINCT HIGHER SATTVA GUNA AND PREFERENTIALLY RECRUITED BRAIN AREAS ASSOCIATED WITH SELF-REGULATION AND INHIBITORY CONTROL.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
10 1359  42 IMMEDIATE EFFECTS OF OM CHANTING ON HEART RATE VARIABILITY MEASURES COMPARED BETWEEN EXPERIENCED AND INEXPERIENCED YOGA PRACTITIONERS. BACKGROUND: CHANTING "OM" IS A FORM OF MEDITATION THAT HAS NUMEROUS HEALTH BENEFITS. HOWEVER, THE NEUROPHYSIOLOGICAL MECHANISMS UNDERPINNING ITS EFFECT ARE SURPRISINGLY SCARCE. THE PRESENT STUDY AIMED TO INVESTIGATE THE EFFECT OF OM CHANTING ON AUTONOMIC MODULATION, USING HEART RATE VARIABILITY (HRV), ON EXPERIENCED YOGA PRACTITIONERS AND YOGA NAIVE PERSONS. METHODS: THIS PROSPECTIVE STUDY INCLUDED 19 YOGA PRACTITIONERS (9 FEMALES AND 10 MALES; GROUP MEAN AGE +/- STANDARD DEVIATION [SD]; 25.9 +/- 3.2 YEARS) AND 17 YOGA NAIVE PERSONS (8 FEMALES AND 9 MALES; GROUP MEAN AGE +/- SD; 24.8 +/- 3.6 YEARS) OF BOTH SEXES AND SIMILAR AGE RANGE. BOTH THE GROUPS WERE ASSESSED FOR HRV INDICES (TIME AND FREQUENCY DOMAIN MEASURES) BEFORE AND AFTER LOUD OM CHANTING FOR 5 MIN. RESULTS: BASELINE COMPARISON USING MANN-WHITNEY U TEST BETWEEN GROUPS SHOWED YOGA PRACTITIONERS HAD SIGNIFICANTLY INCREASED HIGH FREQUENCY (HF) POWER (P < 0.029) THAN NONYOGA PRACTITIONERS, SIGNIFYING A STATE OF TRANQUILITY BEFORE THE CHANTING OF OM. AFTER 5 MIN OF LOUD CHANTING OF OM, A COMPARISON BETWEEN GROUPS ASSESSED USING WILCOXON SIGNED RANKS TEST REVEALED: HF POWER, A COMPONENT OF THE PARASYMPATHETIC NERVOUS SYSTEM, WAS FURTHER AMPLIFIED WITH A SIGNIFICANTLY INCREASE (P < 0.001) IN THE YOGA PRACTITIONERS GROUP COMPARED TO NONYOGA PRACTITIONERS. FURTHERMORE, THIS INCREASE IN HF POWER WAS POSITIVELY CORRELATED WITH THE YEARS OF EXPERIENCE IN YOGA. CONCLUSION: THE PRESENT STUDY SHOWED THAT A BRIEF CHANTING OF OM (5 MIN) MIGHT ENHANCE PARASYMPATHETIC NERVOUS SYSTEM ACTIVITY, PROMOTE RELAXATION, AND PROVIDE CALMNESS. FURTHER, THIS EXPERIENCE MAY BE ACHIEVED EFFECTIVELY IN INDIVIDUALS EXPERIENCED IN YOGA THAN NONYOGA PRACTITIONERS.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
11 1353  29 IMMEDIATE EFFECT OF SPECIFIC NOSTRIL MANIPULATING YOGA BREATHING PRACTICES ON AUTONOMIC AND RESPIRATORY VARIABLES. THE EFFECT OF RIGHT, LEFT, AND ALTERNATE NOSTRIL YOGA BREATHING (I.E., RNYB, LNYB, AND ANYB, RESPECTIVELY) WERE COMPARED WITH BREATH AWARENESS (BAW) AND NORMAL BREATHING (CTL). AUTONOMIC AND RESPIRATORY VARIABLES WERE STUDIED IN 21 MALE VOLUNTEERS WITH AGES BETWEEN 18 AND 45 YEARS AND EXPERIENCE IN THE YOGA BREATHING PRACTICES BETWEEN 3 AND 48 MONTHS. SUBJECTS WERE ASSESSED IN FIVE EXPERIMENTAL SESSIONS ON FIVE SEPARATE DAYS. THE SESSIONS WERE IN FIXED POSSIBLE SEQUENCES AND SUBJECTS WERE ASSIGNED TO A SEQUENCE RANDOMLY. EACH SESSION WAS FOR 40 MIN; 30 MIN FOR THE BREATHING PRACTICE, PRECEDED AND FOLLOWED BY 5 MIN OF QUIET SITTING. ASSESSMENTS INCLUDED HEART RATE VARIABILITY, SKIN CONDUCTANCE, FINGER PLETHYSMOGRAM AMPLITUDE, BREATH RATE, AND BLOOD PRESSURE. FOLLOWING RNYB THERE WAS A SIGNIFICANT INCREASE IN SYSTOLIC, DIASTOLIC AND MEAN PRESSURE. IN CONTRAST, THE SYSTOLIC AND DIASTOLIC PRESSURE DECREASED AFTER ANYB AND THE SYSTOLIC AND MEAN PRESSURE WERE LOWER AFTER LNYB. HENCE, UNILATERAL NOSTRIL YOGA BREATHING PRACTICES APPEAR TO INFLUENCE THE BLOOD PRESSURE IN DIFFERENT WAYS. THESE EFFECTS SUGGEST POSSIBLE THERAPEUTIC APPLICATIONS.	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
12  462  40 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.

BACKGROUND YOGA BREATHING TECHNIQUES LIKE HIGH-FREQUENCY YOGA BREATHING (HFYB) AND BREATH AWARENESS (BAW) HAVE BEEN ASSOCIATED WITH IMPROVED PERFORMANCE IN THE SHAPE AND SIZE DISCRIMINATION TASK. A PUBMED SEARCH OF THE LITERATURE REVEALED THAT ALTERNATE-NOSTRIL BREATHING HAS BEEN SHOWN TO IMPROVE PERFORMANCE IN ATTENTION TASKS, BUT THE EFFECT ON TACTILE PERCEPTION HAS NOT BEEN STUDIED. HENCE, THE PRESENT STUDY WAS DESIGNED TO ASSESS THE IMMEDIATE EFFECTS OF ALTERNATE-NOSTRIL YOGA BREATHING (ANYB) COMPARED TO BREATH AWARENESS ON SHAPE AND SIZE DISCRIMINATION AND STATE ANXIETY. MATERIAL AND METHODS FIFTY HEALTHY MALE VOLUNTEERS AGES 20-50 YEARS (GROUP MEAN +/-S.D., 28.4+/-8.2 YEARS) WERE RECRUITED. EACH PARTICIPANT WAS ASSESSED IN 3 SESSIONS CONDUCTED ON 3 SEPARATE DAYS AT THE SAME TIME OF DAY. THE 3 SESSIONS WERE (I) ALTERNATE-NOSTRIL YOGA BREATHING (ANYB), (II) BREATH AWARENESS (BAW), AND (III) QUIET SITTING (QS), AND THE SEQUENCE OF THE SESSIONS WAS RANDOMLY ALLOCATED. THE SHAPE AND SIZE DISCRIMINATION TASK AND STATE ANXIETY WERE ASSESSED BEFORE AND AFTER ALL 3 SESSIONS. REPEATED MEASURES ANALYSIS OF VARIANCE (RM-ANOVA) FOLLOWED BY POST HOC TESTS FOR MULTIPLE COMPARISONS, WHICH WERE BONFERRONI-ADJUSTED, WERE PERFORMED TO COMPARE DATA BEFORE AND AFTER ALL 3 SESSIONS USING SPSS VERSION 18.0. RESULTS THE ERRORS SCORES IN THE SHAPE AND SIZE DISCRIMINATION TASK SHOWED A SIGNIFICANT REDUCTION AFTER THE ANYB SESSION (P<0.001). A SIGNIFICANT REDUCTION WAS FOUND IN THE LEVEL OF STATE ANXIETY AFTER BREATH AWARENESS (P<0.05) AND QUIET SITTING SESSIONS (P<0.001). CONCLUSIONS THE PRESENT RESULTS SUGGEST THAT ANYB: (I) IMPROVES PERFORMANCE IN A TASK WHICH REQUIRES PERCEPTUAL SENSITIVITY AND FOCUSED ATTENTION, BUT (II) DOES NOT REDUCE STATE ANXIETY FOLLOWING THIS TASK.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
14   72  35 A FUNCTIONAL NEAR-INFRARED SPECTROSCOPY STUDY OF HIGH-FREQUENCY YOGA BREATHING COMPARED TO BREATH AWARENESS. BACKGROUND HIGH-FREQUENCY YOGA BREATHING (BREATH RATE OF 2.0 HZ) HAS BEEN ASSOCIATED WITH CHANGES IN OXY-HEMOGLOBIN IN THE PREFRONTAL REGION OF THE BRAIN. THE PRESENT STUDY ASSESSED THE EFFECTS OF HIGH-FREQUENCY YOGA BREATHING (HFYB) AT 1.0 HZ ON FRONTAL OXY-HEMOGLOBIN (OXY-HB) AND DEOXY-HEMOGLOBIN (DEOXY-HB). MATERIAL AND METHODS FORTY HEALTHY MALE PARTICIPANTS WERE RECRUITED FOR THE STUDY. THE EXPERIMENTAL GROUP CONSISTED OF 20 PARTICIPANTS 23-40 YEARS OLD (GROUP MEAN +/-S.D., 26.4+/-4.7 YEARS) WITH AT LEAST 3 MONTHS OF EXPERIENCE PERFORMING HFYB (GROUP MEAN +/-S.D., 16.3+/-9.8 MONTHS). THE CONTROL GROUP CONSISTED OF 20 PARTICIPANTS AGES 23-38 YEARS (GROUP MEAN AGE +/- S.D., 27.4+/-4.1 YEARS), WHO WERE SEATED QUIETLY FOR THE SAME DURATION AND THEIR AVERAGE EXPERIENCE OF YOGA PRACTICE WAS (+/-S.D.) 4.3+/-2.7 MONTHS. EACH PARTICIPANT IN THE EXPERIMENTAL GROUP WAS ASSESSED AT 2 SESSIONS (HFYB AND BREATH AWARENESS [BAW]) ON ALTERNATE DAYS. HEMODYNAMIC CHANGES WERE ASSESSED USING A FUNCTIONAL NEAR-INFRARED SPECTROSCOPY SENSOR PLACED OVER THE FOREHEAD. DATA WERE ANALYZED USING REPEATED-MEASURES ANALYSES OF VARIANCE FOLLOWED BY POST HOC BONFERRONI ADJUSTMENT. RESULTS A SIGNIFICANT REDUCTION WAS OBSERVED IN OXY-HB DURING AND AFTER HFYB ON THE LEFT AND RIGHT SIDES COMPARED TO VALUES BEFORE. WE ALSO FOUND A SIGNIFICANT REDUCTION IN DEOXY-HB DURING AND AFTER THE QUIET SITTING CONTROL SESSION COMPARED TO PRE-SESSION VALUES ON LEFT AND RIGHT SIDES. CONCLUSIONS THE DECREASE IN OXY-HB DURING AND AFTER HFYB SUGGESTS THAT THERE WAS NO FRONTAL ACTIVATION DURING HFYB WHEN PRACTICED AT THE RATE OF 1.0 HZ.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
15 1610  39 METABOLIC AND VENTILATORY CHANGES DURING AND AFTER HIGH-FREQUENCY YOGA BREATHING. BACKGROUND PRACTICING HIGH-FREQUENCY YOGA BREATHING (HFYB) INDUCED A HYPERMETABOLIC STATE IN A SINGLE SUBJECT DURING THE PRACTICE BUT THE EFFECT HAS NOT BEEN STUDIED IN MULTIPLE PRACTITIONERS. MATERIAL AND METHODS HEALTHY MALE VOLUNTEERS (N=47, GROUP MEAN AGE +/- S.D., 23.2 +/- 4.1 YEARS) WERE RECRUITED AS AN EXPERIMENTAL GROUP AND ANOTHER TWENTY VOLUNTEERS WERE RECRUITED AS A CONTROL GROUP. THE EXPERIMENTAL GROUP PRACTICED EITHER HFYB (BREATH RATE 1.0 HZ) OR BREATH AWARENESS (BAW) ON TWO SEPARATE DAYS. THE SEQUENCE WAS REVERSED FOR ALTERNATE PARTICIPANTS. THE CONTROL GROUP WAS ASSESSED UNDER SIMILAR CONDITIONS WHILE SITTING AT EASE. THE BREATH RATE (RR), TIDAL VOLUME (VT), VENTILATION (VE), VO2, VCO2, ARTERIAL PCO2 AND ENERGY EXPENDITURE (EE KCAL/DAY) WERE ASSESSED FOR 35 MINUTES USING AN OPEN CIRCUIT OXYGEN CONSUMPTION ANALYZER. THE ASSESSMENT PERIOD WAS DIVIDED INTO BEFORE, DURING AND AFTER CONDITIONS. REPEATED MEASURES ANALYSES OF VARIANCE (ANOVA) WERE USED TO COMPARE DATA RECORDED DURING AND AFTER THE TWO PRACTICES WITH DATA RECORDED BEFORE. BEFORE-AFTER COMPARISONS IN THE CONTROL GROUP WERE WITH PAIRED T-TESTS. RESULTS THE MOST RELEVANT SIGNIFICANT CHANGES WERE INCREASES IN VE, VO2, VCO2 AND EE DURING HFYB, WHILE THE SAME VARIABLES DECREASED DURING THE CONTROL PERIOD. HOWEVER AFTER HFYB THERE WAS NO CHANGE IN VO2 OR EE, ALTHOUGH VE DECREASED AS IT DID AFTER THE CONTROL PERIOD. CONCLUSIONS HFYB INDUCES A HYPERMETABOLIC STATE FOR THE DURATION OF THE PRACTICE WHICH RETURNS TO BASELINE AFTER HFYB SUGGESTING A POSSIBLE APPLICATION FOR HFYB IN HYPOMETABOLIC STATES.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
16 2510  33 YOGA BREATHING THROUGH A PARTICULAR NOSTRIL INCREASES SPATIAL MEMORY SCORES WITHOUT LATERALIZED EFFECTS. UNINOSTRIL BREATHING FACILITATES THE PERFORMANCE ON SPATIAL AND VERBAL COGNITIVE TASKS, SAID TO BE RIGHT AND LEFT BRAIN FUNCTIONS, RESPECTIVELY. SINCE HEMISPHERIC MEMORY FUNCTIONS ARE ALSO KNOWN TO BE LATERALIZED, THE PRESENT STUDY ASSESSED THE EFFECTS OF UNINOSTRIL BREATHING ON THE PERFORMANCE IN VERBAL AND SPATIAL MEMORY TESTS. SCHOOL CHILDREN (N = 108 WHOSE AGES RANGED FROM 10 TO 17 YEARS) WERE RANDOMLY ASSIGNED TO FOUR GROUPS. EACH GROUP PRACTICED A SPECIFIC YOGA BREATHING TECHNIQUE: (I) RIGHT NOSTRIL BREATHING, (II) LEFT NOSTRIL BREATHING, (III) ALTERNATE NOSTRIL BREATHING, OR (IV) BREATH AWARENESS WITHOUT MANIPULATION OF NOSTRILS. THESE TECHNIQUES WERE PRACTICED FOR 10 DAYS. VERBAL AND SPATIAL MEMORY WAS ASSESSED INITIALLY AND AFTER 10 DAYS. AN AGE-MATCHED CONTROL GROUP OF 27 WERE SIMILARLY ASSESSED. ALL 4 TRAINED GROUPS SHOWED A SIGNIFICANT INCREASE IN SPATIAL TEST SCORES AT RETEST, BUT THE CONTROL GROUP SHOWED NO CHANGE. AVERAGE INCREASE IN SPATIAL MEMORY SCORES FOR THE TRAINED GROUPS WAS 84%. IT APPEARS YOGA BREATHING INCREASES SPATIAL RATHER THAN VERBAL SCORES, WITHOUT A LATERALIZED EFFECT.	1997	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
17  298  37 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
18  867  50 EFFECT OF YOGA REGIMEN ON LUNG FUNCTIONS INCLUDING DIFFUSION CAPACITY IN CORONARY ARTERY DISEASE PATIENTS: A RANDOMIZED CONTROLLED STUDY. BACKGROUND: LUNG FUNCTIONS ARE FOUND TO BE IMPAIRED IN CORONARY ARTERY DISEASE (CAD), CONGESTIVE HEART FAILURE, LEFT VENTRICULAR DYSFUNCTION, AND AFTER CARDIAC SURGERY. DIFFUSION CAPACITY PROGRESSIVELY WORSENS AS THE SEVERITY OF CAD INCREASES DUE TO REDUCTION IN LUNG TISSUE PARTICIPATING IN GAS EXCHANGE. AIMS AND OBJECTIVES: PRANAYAMA BREATHING EXERCISES AND YOGIC POSTURES MAY PLAY AN IMPRESSIVE ROLE IN IMPROVING CARDIO-RESPIRATORY EFFICIENCY AND FACILITATING GAS DIFFUSION AT THE ALVEOLO-CAPILLARY MEMBRANE. THIS STUDY WAS DONE TO SEE THE EFFECT OF YOGA REGIMEN ON LUNG FUNCTIONS PARTICULARLY DIFFUSION CAPACITY IN CAD PATIENTS. MATERIALS AND METHODS: A TOTAL OF 80 STABLE CAD PATIENTS BELOW 65 YEARS OF AGE OF BOTH SEXES WERE SELECTED AND RANDOMIZED INTO TWO GROUPS OF 40 EACH. GROUP I CAD PATIENTS WERE GIVEN YOGA REGIMEN FOR 3 MONTHS WHICH CONSISTED OF YOGIC POSTURES, PRANAYAMA BREATHING EXERCISES, DIETARY MODIFICATION, AND HOLISTIC TEACHING ALONG WITH THEIR CONVENTIONAL MEDICINE WHILE GROUP II CAD PATIENTS WERE PUT ONLY ON CONVENTIONAL MEDICINE. LUNG FUNCTIONS INCLUDING DIFFUSION CAPACITY WERE RECORDED THRICE IN BOTH THE GROUPS: 0 DAY AS BASELINE, 22(ND) DAY AND ON 90(TH) DAY BY USING COMPUTERIZED MS MEDISOFT CARDIO-RESPIRATORY INSTRUMENT, HYP'AIR COMPACT MODEL OF CARDIO-RESPIRATORY TESTING MACHINE WAS MANUFACTURED BY P K MORGAN, INDIA. THE RECORDED PARAMETERS WERE STATISTICALLY ANALYZED BY REPEATED MEASURES ANOVA FOLLOWED BY TUKEY'S TEST IN BOTH THE GROUPS. CARDIOVASCULAR PARAMETERS WERE ALSO COMPARED BEFORE AND AFTER INTERVENTION IN BOTH THE GROUPS. RESULTS: STATISTICALLY SIGNIFICANT IMPROVEMENTS WERE SEEN IN SLOW VITAL CAPACITY, FORCED VITAL CAPACITY, PEAK EXPIRATORY FLOW RATE, MAXIMUM VOLUNTARY VENTILATION, AND DIFFUSION FACTOR/ TRANSFER FACTOR OF LUNG FOR CARBON MONOXIDE AFTER 3 MONTHS OF YOGA REGIMEN IN GROUP I. FORCED EXPIRATORY VOLUME IN 1(ST) SEC (FEV1), AND FEV1 % ALSO SHOWED A TREND TOWARD IMPROVEMENT ALTHOUGH NOT STATISTICALLY SIGNIFICANT. HR, SBP AND DBP ALSO SHOWED SIGNIFICANT IMPROVEMENT IN GROUP-I PATIENTS WHO FOLLOWED YOGA REGIMEN. CONCLUSIONS: YOGA REGIMEN WAS FOUND TO IMPROVE LUNG FUNCTIONS AND DIFFUSION CAPACITY IN CAD PATIENTS BESIDES IMPROVING CARDIOVASCULAR FUNCTIONS. THUS, IT CAN BE USED AS A COMPLIMENTARY OR ADJUNCT THERAPY ALONG WITH THE CONVENTIONAL MEDICINE FOR THEIR TREATMENT AND REHABILITATION.	2015	

19 1875  31 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
20 1578  33 MEASUREMENT OF THE EFFECT OF ISHA YOGA ON CARDIAC AUTONOMIC NERVOUS SYSTEM USING SHORT-TERM HEART RATE VARIABILITY. BACKGROUND: BENEFICIAL EFFECTS OF YOGA HAVE BEEN POSTULATED TO BE DUE TO MODULATION OF THE AUTONOMIC NERVOUS SYSTEM. OBJECTIVE: TO ASSESS THE EFFECT OF ISHA YOGA PRACTICES ON CARDIOVASCULAR AUTONOMIC NERVOUS SYSTEM THROUGH SHORT-TERM HEART RATE VARIABILITY (HRV). DESIGN OF THE STUDY: SHORT-TERM HRV OF LONG-TERM REGULAR HEALTHY 14 (12 MALES AND 2 FEMALES) ISHA YOGA PRACTITIONERS WAS COMPARED WITH THAT OF AGE- AND GENDER-MATCHED 14 (12 MALES AND 2 FEMALES) NON-YOGA PRACTITIONERS. METHODS AND MATERIALS: ECG LEAD II AND RESPIRATORY MOVEMENTS WERE RECORDED IN BOTH GROUPS USING POLYRITE DURING SUPINE REST FOR 5 MIN AND CONTROLLED DEEP BREATHING FOR 1 MINUTE. FREQUENCY DOMAIN ANALYSIS [RR INTERVAL IS THE MEAN OF DISTANCE BETWEEN SUBSEQUENT R WAVE PEAKS IN ECG], LOW FREQUENCY (LF) POWER, HIGH FREQUENCY (HF) POWER, LF NORMALIZED UNITS (NU), HF NU, LF/HF RATIO] AND TIME DOMAIN ANALYSIS [STANDARD DEVIATION OF NORMAL TO NORMAL INTERVAL (SDNN), SQUARE OF MEAN SQUARED DIFFERENCE OF SUCCESSIVE NORMAL TO NORMAL INTERVALS (RMSSD), NORMAL TO NORMAL INTERVALS WHICH ARE DIFFERING BY 50 MS (NN50), AND PERCENTAGE OF NN50 (PNN50)] OF HRV VARIABLES WERE ANALYZED FOR SUPINE REST. TIME DOMAIN ANALYSIS WAS RECORDED FOR DEEP BREATHING. RESULTS: RESULTS SHOWED STATISTICALLY SIGNIFICANT DIFFERENCES BETWEEN ISHA YOGA PRACTITIONERS AND CONTROLS IN BOTH FREQUENCY AND TIME DOMAIN ANALYSES OF HRV INDICES, WITH NO DIFFERENCE IN RESTING HEART RATE BETWEEN THE GROUPS. CONCLUSIONS: PRACTITIONERS OF ISHA YOGA SHOWED WELL-BALANCED BENEFICIAL ACTIVITY OF VAGAL EFFERENTS, AN OVERALL INCREASED HRV, AND SYMPATHOVAGAL BALANCE, COMPARED TO NON-YOGA PRACTITIONERS DURING SUPINE REST AND DEEP BREATHING.	2012
