1 2362 164 VOLITIONAL YOGA BREATHING INFLUENCES ATTENTION AND ANXIETY: AN EXPLORATORY RANDOMIZED CROSSOVER STUDY. BACKGROUND: PREVIOUS STUDIES ASSESSED YOGA BREATHING PRACTICES INDIVIDUALLY. THIS EXPLORATORY, RANDOMIZED CROSSOVER STUDY ASSESSED ATTENTION AND ANXIETY FOLLOWING FOUR YOGA BREATHING PRACTICES, BREATH AWARENESS, AND QUIET SEATED REST. MATERIALS AND METHODS: THIRTY-EIGHT MALE VOLUNTEERS BETWEEN 20 AND 37 YEARS (GROUP MEAN AGE +/- SD; 24.08 +/- 4.01 YEARS) WERE ASSESSED IN SIX SESSIONS IN RANDOM ORDER (WWW.RANDOMIZER.ORG) ON SEPARATE DAYS. THE SESSIONS WERE: (I) ALTERNATE NOSTRIL YOGA BREATHING, (II) BELLOWS YOGA BREATHING, (III) BUMBLEBEE YOGA BREATHING, (IV) HIGH-FREQUENCY YOGA BREATHING, (V) BREATH AWARENESS, AND (VI) QUIET SEATED REST. THE SESSIONS WERE FOR 18 MIN EACH. SIX LETTER CANCELLATION TEST (SLCT) AND SPIELBERGER'S STATE TRAIT ANXIETY INVENTORY-STATE (STAI-S) WERE ADMINISTERED PRE AND POST EACH SESSION. DATA ANALYSIS USED GENERAL LINEAR MIXED MODEL ANALYSIS, WITH FIXED EFFECT OF STATES (PRE AND POST) AND SESSIONS. RESULTS: A SIGNIFICANT MAIN EFFECT OF STATES WAS OBSERVED ON TOTAL ATTEMPTED (F1,407 = 5.374, P = 0.021) AND NET ATTEMPTED SCORES (F1,407 = 6.178, P = 0.013) OF THE SLCT, WITH A SIGNIFICANT INCREASE IN SCORES FOLLOWING HIGH-FREQUENCY YOGA BREATHING (PADJ = 0.031 FOR TOTAL ATTEMPTED SCORES; PADJ = 0.029 FOR NET ATTEMPTED SCORES). ALSO, A SIGNIFICANT MAIN EFFECT OF STATES ON STAI-S SCORES WAS OBSERVED (F1,407 = 33.979, P < 0.001), WITH A SIGNIFICANT DECREASE IN SCORES FOLLOWING ALTERNATE NOSTRIL YOGA BREATHING (PADJ = 0.001), BELLOWS YOGA BREATHING (PADJ = 0.008), BUMBLEBEE YOGA BREATHING (PADJ = 0.002), AND HIGH-FREQUENCY YOGA BREATHING (PADJ = 0.042) COMPARED TO THE CORRESPONDING PRE STATE. THERE WAS A SIGNIFICANT MAIN EFFECT OF SESSIONS (F5,407 = 3.043, P = 0.010) ON STAI-S SCORES, WITH SCORES POST ALTERNATE NOSTRIL YOGA BREATHING SIGNIFICANTLY LOWER THAN POST BREATH AWARENESS (PADJ = 0.037). CONCLUSION: FOLLOWING HIGH-FREQUENCY YOGA BREATHING SUSTAINED ATTENTION WAS BETTER THAN BEFORE WHILE STATE ANXIETY DECREASED IN POST-PRE COMPARISONS OF ALTERNATE NOSTRIL YOGA BREATHING, BELLOWS YOGA BREATHING, BUMBLEBEE YOGA BREATHING, AND HIGH-FREQUENCY YOGA BREATHING. THE DIFFERENCES BETWEEN BREATHING PRACTICES MAY BE DUE TO DIFFERENCES IN DEGREE OF VOLITIONAL REGULATION OF BREATHING AND IN THE BREATH PATTERNS MODIFIED VOLITIONALLY. THE GENERALIZABILITY OF THE FINDINGS WAS LIMITED BY INCLUDING AN ALL MALE, YOGA EXPERIENCED SAMPLE. FUTURE RESEARCH SHOULD INCLUDE PARTICIPANTS OF BOTH GENDERS AND COULD INCLUDE DIFFERENT LEVELS OF YOGA EXPERIENCE, WITH ASSESSMENTS INCLUDING OBJECTIVE MEASURES OF ATTENTION AND ANXIETY.	2022	

2 1351  57 IMMEDIATE EFFECT OF A YOGA BREATHING PRACTICE ON ATTENTION AND ANXIETY IN PRE-TEEN CHILDREN. PRE-TEEN CHILDREN FACE STRESSORS RELATED TO THEIR TRANSITION FROM CHILDHOOD TO ADOLESCENCE, WITH A SIMULTANEOUS INCREASE IN ACADEMIC PRESSURE. THE PRESENT STUDY COMPARED THE IMMEDIATE EFFECTS OF 18 MIN OF (I) HIGH FREQUENCY YOGA BREATHING WITH (II) YOGA-BASED BREATH AWARENESS AND (III) SITTING QUIETLY, ON (A) ATTENTION AND (B) ANXIETY, IN 61 PRE-TEEN CHILDREN (AGED BETWEEN 11 AND 12 YEARS; 25 GIRLS). ATTENTION WAS ASSESSED USING A SIX LETTER CANCELLATION TASK AND SPIELBERGER'S STATE TRAIT ANXIETY INVENTORY STAI-S WAS USED TO MEASURE ANXIETY BEFORE AND AFTER THE THREE PRACTICES, PRACTICED ON SEPARATE DAYS. REPEATED MEASURES ANOVA, FOLLOWED BY BONFERRONI ADJUSTED POST-HOC ANALYSES SHOWED AN INCREASE IN TOTAL ATTEMPTS AND NET SCORES AFTER HIGH FREQUENCY YOGA BREATHING (P < 0.05), WHILE WRONG ATTEMPTS INCREASED AFTER YOGA BASED BREATH AWARENESS (P < 0.05). ANXIETY DECREASED COMPARABLY AFTER ALL THREE INTERVENTIONS. THE 25 GIRLS IN THE GROUP HAD THE SAME TREND OF RESULTS AS THE WHOLE GROUP WITH RESPECT TO THE ATTENTION-BASED CANCELLATION TASK, WHILE BOYS SHOWED NO, HOW SINCE CHANGE. FOR BOTH GIRLS AND BOYS, ANXIETY DECREASED AFTER ALL THREE 18MIN INTERVENTIONS. THE RESULTS SUGGEST THAT HIGH FREQUENCY YOGA BREATHING COULD BE A SHORT, USEFUL SCHOOL BASED PRACTICE TO IMPROVE ATTENTION AND REDUCE ANXIETY.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
3 1354  32 IMMEDIATE EFFECT OF THREE YOGA BREATHING TECHNIQUES ON PERFORMANCE ON A LETTER-CANCELLATION TASK. THE EFFECTS OF THREE YOGA BREATHING PRACTICES WERE EVALUATED ON PERFORMANCE ON A LETTER-CANCELLATION TASK WHICH IS A LEFT-HEMISPHERE DOMINANT TASK. THE THREE YOGA BREATHING PRACTICES (RIGHT, LEFT, AND ALTERNATE NOSTRIL BREATHING) WERE SELECTED BECAUSE UNILATERAL FORCED NOSTRIL BREATHING STIMULATES THE CONTRALATERAL HEMISPHERE. THERE WERE 20 MALE VOLUNTEERS WHOSE AGES RANGED FROM 20 TO 45 YEARS (M AGE=28.4 YR., SD=5.7). ALL SUBJECTS WERE ASSESSED BEFORE AND AFTER FOUR SESSIONS, I.E., RIGHT NOSTRIL YOGA BREATHING, LEFT NOSTRIL YOGA BREATHING, ALTERNATE NOSTRIL YOGA BREATHING, AND BREATH AWARENESS AS A CONTROL. THE LETTER-CANCELLATION TASK SCORES WERE SIGNIFICANTLY IMPROVED, I.E., THERE WERE FEWER ERRORS FOLLOWING RIGHT AND ALTERNATE NOSTRIL YOGA BREATHING (WILCOXON PAIRED SIGNED-RANKS TEST). THE IMPROVED PERFORMANCE MAY BE RELATED TO THE ENHANCEMENT OF CONTRALATERAL HEMISPHERE FUNCTION FOUND WITH SELECTIVE NOSTRIL BREATHING.	2007	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
4 1726  56 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
5  277  39 ADDITIONAL PRACTICE OF YOGA BREATHING WITH INTERMITTENT BREATH HOLDING ENHANCES PSYCHOLOGICAL FUNCTIONS IN YOGA PRACTITIONERS: A RANDOMIZED CONTROLLED TRIAL. BACKGROUND AND OBJECTIVE: THE PRACTICE OF YOGA IS ASSOCIATED WITH ENHANCED PSYCHOLOGICAL WELLBEING. THE CURRENT STUDY ASSESSED THE CORRELATION BETWEEN THE DURATION OF YOGA PRACTICE WITH STATE MINDFULNESS, MIND-WANDERING AND STATE ANXIETY. ALSO, WE EXAMINED IF AN ADDITIONAL 20 MIN OF YOGA BREATHING WITH INTERMITTENT BREATH HOLDING (EXPERIMENTAL GROUP) FOR 8 WEEKS WOULD AFFECT THESE PSYCHOLOGICAL VARIABLES MORE THAN REGULAR YOGA PRACTICE (CONTROL GROUP) ALONE. METHODS: ONE HUNDRED SIXTEEN SUBJECTS WERE RANDOMLY ASSIGNED TO EXPERIMENTAL (N = 60) AND CONTROL (N = 56) GROUPS. STATE MINDFULNESS ATTENTION AWARENESS SCALE (SMAAS), MIND-WANDERING QUESTIONNAIRE (MWQ) AND STATE ANXIETY INVENTORY WERE ADMINISTERED AT BASELINE AND AT THE END OF 8 WEEKS. RESULTS: BASELINE ASSESSMENT REVEALED A POSITIVE CORRELATION BETWEEN DURATION OF YOGA PRACTICE WITH SMAAS SCORES AND NEGATIVE CORRELATION WITH MWQ AND STATE ANXIETY SCORES. AT THE END OF 8 WEEKS, BOTH GROUPS DEMONSTRATED ENHANCED PSYCHOLOGICAL FUNCTIONS, BUT THE EXPERIMENTAL GROUP RECEIVING ADDITIONAL YOGA BREATHING PERFORMED BETTER THAN THE GROUP PRACTICING YOGA ALONE. CONCLUSION: AN ADDITIONAL PRACTICE OF YOGA BREATHING WITH INTERMITTENT BREATH HOLDING WAS FOUND TO ENHANCE THE PSYCHOLOGICAL FUNCTIONS IN YOUNG ADULT YOGA PRACTITIONERS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
6 1695  59 P300 FOLLOWING FOUR VOLUNTARILY REGULATED YOGA BREATHING PRACTICES AND BREATH AWARENESS. ATTENTION WAS INFLUENCED BY YOGA BREATHING IN PREVIOUSLY PUBLISHED RESEARCH. EACH YOGA BREATHING PRACTICE UNIQUELY MODIFIES SPECIFIC BREATH CHARACTERISTICS. DIFFERENCES IN THE STUDY DESIGNS, ASSESSMENT METHODS AND INTERVENTIONS RESULTED IN DIFFICULTY IN COMPARING EFFECTS BETWEEN YOGA BREATHING PRACTICES. THIS STUDY AIMED (I) TO COMPARE FOUR YOGA BREATHING PRACTICES ON ATTENTION USING AN AUDITORY ODDBALL TASK AND (II) TO DETERMINE CARDIAC AUTONOMIC ACTIVITY ASSOCIATED WITH ATTENTION USING HEART RATE VARIABILITY. P300 EVENT RELATED POTENTIAL WAS RECORDED SIMULTANEOUSLY WITH HEART RATE VARIABILITY BEFORE AND AFTER 18-MINUTE PERIODS EACH OF (I) HIGH FREQUENCY YOGA BREATHING (WITH INCREASED BREATH FREQUENCY), (II) BELLOWS YOGA BREATHING (WITH INCREASED DEPTH OF RESPIRATION), (III) ALTERNATE NOSTRIL YOGA BREATHING (WITH ALTERNATE NOSTRIL PATENCY), (IV) BUMBLEBEE YOGA BREATHING (WITH PROLONGED EXHALE), (V) BREATH AWARENESS (WITH ATTENTION TO THE BREATH) AND (VI) QUIET SEATED REST AS CONTROL IN 38 YOGA EXPERIENCED MALES (AVERAGE AGE +/- SD; 24.08 +/- 4.01 YEARS). THE SIX SESSIONS WERE ON SEPARATE, RANDOMLY ALLOCATED DAYS. THE P300 PEAK AMPLITUDE RECORDED AT PZ WAS SIGNIFICANTLY INCREASED AFTER FOUR YOGA BREATHING PRACTICES (BONFERRONI ADJUSTED POST-HOC TESTS, REPEATED MEASURES ANOVA). NO SIGNIFICANT CHANGES WERE NOTED IN HEART RATE VARIABILITY FOLLOWING YOGA BREATHING OR CONTROL SESSIONS. THESE FINDINGS SUGGEST THAT THE FOUR YOGA BREATHING PRACTICES INCREASE THE ATTENTIONAL NEURAL RESOURCES ENGAGED FOR THIS AUDITORY ODDBALL TASK, IRRESPECTIVE OF THE CHARACTERISTIC OF BREATH UNIQUELY REGULATED IN THE FOUR YOGA BREATHING PRACTICES.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
7  295  44 AGE RELATED DIFFERENCES OF SELECTED HATHA YOGA PRACTICES ON ANTHROPOMETRIC CHARACTERISTICS, MUSCULAR STRENGTH AND FLEXIBILITY OF HEALTHY INDIVIDUALS. BACKGROUND: PHYSIOLOGICAL BENEFITS OF YOGA ON VOLUNTEERS OF A PARTICULAR AGE GROUP ARE AVAILABLE. HOWEVER, REPORTS ON EFFICACY OF A SPECIFIC YOGA PACKAGE ON THE POPULACE OF DIFFERENT AGE GROUPS FROM SIMILAR OCCUPATIONAL BACKGROUND IS STILL VERY LIMITED. THEREFORE, THE PRESENT STUDY WAS CONDUCTED TO APPRAISE THE EFFECT OF A SPECIFIC HATHA YOGA PACKAGE ON ANTHROPOMETRIC CHARACTERISTICS, FLEXIBILITY AND MUSCULAR STRENGTH OF HEALTHY INDIVIDUALS OF DIFFERENT AGE GROUPS FROM SIMILAR OCCUPATIONAL TRADE. MATERIALS AND METHODS: A TOTAL OF 71 PARTICIPANTS (GROUP ALL) FROM INDIAN AIR FORCE GROUND PERSONNEL VOLUNTEERED AND AGE WISE DIVIDED INTO 3 GROUPS - (I) GROUP I (GR. - I) (N1 = 27, 20-29 YEARS), (II) GROUP II (GR. - II) (N2 = 21, 30-39 YEARS) AND (III) GROUP III (GR. - III) (N3 = 23, 40-49 YEARS). ALL THE PARTICIPANTS UNDERGONE SELECTED HATHA YOGA TRAINING FOR 1 H DAILY FOR A PERIOD OF 12 WEEKS. PARAMETERS WERE RECORDED BEFORE AND AFTER THE TRAINING. PRE AND POST TRAINING DIFFERENCES WERE ASSESSED BY STUDENT'S T-TEST. RESULTS: BODY WEIGHT (ALL, GR. - II AND GR. - III [ALL P < 0.05]), BODY MASS INDEX (GR. - II AND GR. - III [BOTH P < 0.01]) AND FAT% (GR. - II AND III [BOTH P < 0.05]) WERE DECREASED SIGNIFICANTLY. NECK CIRCUMFERENCE WAS INCREASED SIGNIFICANTLY IN GR. - I (P < 0.05) BUT DECREASED SIGNIFICANTLY IN GR. - III (P < 0.05). CHEST CIRCUMFERENCE (ALL (P < 0.001), IN GR. - I AND II [BOTH P < 0.05]), GRIP STRENGTH (ALL [LEFT: P < 0.01 AND RIGHT: P < 0.05], IN GR. - I [LEFT: P < 0.05 AND RIGHT: P < 0.01], IN GR. - II [RIGHT: P < 0.05] AND IN GR. - III [LEFT: P < 0.05 AND RIGHT: P < 0.01]), BACK LEG STRENGTH (GROUP WISE P < 0.001, P < 0.05, P < 0.01 AND P < 0.05 RESPECTIVELY) AND FLEXIBILITY (ALL P < 0.001) WERE INCREASED SIGNIFICANTLY. SUMMARY AND CONCLUSION: HATHA YOGA CAN IMPROVE ANTHROPOMETRIC CHARACTERISTICS, MUSCULAR STRENGTH AND FLEXIBILITY AMONG VOLUNTEERS OF DIFFERENT AGE GROUP AND CAN ALSO BE HELPFUL IN PREVENTING AND ATTENUATING AGE RELATED DETERIORATION OF THESE PARAMETERS.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
8  769  39 EFFECT OF UNILATERAL LEFT NOSTRIL BREATHING (CHANDRA ANGA PRANAYAMA) ON COGNITIVE FUNCTION IN HEALTHY YOGA-NAIVE INDIVIDUALS: A RANDOMIZED, CONTROLLED, PILOT STUDY. INTRODUCTION: BREATHING MODULATES CORTICAL NEURONAL ACTIVITY. VARIOUS BREATHING EXERCISES ARE PURPORTED TO HAVE SPECIFIC EFFECTS ON EMOTIONAL AND COGNITIVE FUNCTIONS. OBJECTIVE: TO DETERMINE THE EFFECT OF UNILATERAL LEFT NOSTRIL BREATHING (ULNB) ON NONLATERALIZED, OVERALL COGNITIVE FUNCTIONS USING COMPUTERIZED PSYCHOMETRIC TESTS. METHODS: A RANDOMIZED, CONTROLLED, PILOT STUDY WAS CONDUCTED AMONG 20 HEALTHY YOGA-NAIVE MEDICAL STUDENTS. ULNB WAS PERFORMED FOR 15 MIN BY THE TEST GROUP (N = 10) AND BREATH AWARENESS BY THE CONTROL GROUP (N = 10). ATTENTION AND PROCESSING SPEED, MEMORY, AND EXECUTIVE FUNCTION WERE ASSESSED USING THE LETTER-DIGIT SUBSTITUTION TEST, STERNBERG MEMORY TASK, AND VICTORIA STROOP TEST, RESPECTIVELY. BASELINE, PRE- AND POSTINTERVENTION SCORES WERE RECORDED. RESULTS: THERE WAS NO SIGNIFICANT DIFFERENCE BETWEEN THE GROUPS IN BASELINE SCORES. IN THE STERNBERG MEMORY TASK, A STATISTICALLY SIGNIFICANT DECREASE IN RESPONSE TIME WAS SEEN IN THE TEST (T(9) = 3.855, P = 0.004) AS WELL AS THE CONTROL GROUP (T(9) = 3.120, P = 0.012); THERE WAS NO SIGNIFICANT DIFFERENCE BETWEEN THE GROUPS. NO SIGNIFICANT EFFECT OF UNLB WAS SEEN IN THE LETTER-DIGIT SUBSTITUTION TEST AND STROOP TEST. CONCLUSIONS: OUR STUDY SHOWED NO DIFFERENCE IN THE EFFECTS OF 15-MIN PRACTICE OF ULNB AND BREATH AWARENESS ON COGNITIVE FUNCTIONS; BOTH IMPROVED MEMORY BUT NOT ATTENTION OR EXECUTIVE FUNCTION.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
9  417  45 BODY TEMPERATURE IN PRACTITIONERS OF A YOGA BREATHING TECHNIQUE CONSIDERED TO BE HEAT GENERATING. CONTEXT: SURYABHEDA PRANAYAMA IS TRADITIONALLY DESCRIBED AS "INCREASING THE INNER FIRE" AND IS BELIEVED TO BE HEAT GENERATING. AIMS: THE PRESENT STUDY AIMED AT DETERMINING WHETHER THE SURFACE BODY TEMPERATURE WOULD INCREASE AFTER SURYABHEDA PRANAYAMA PRACTICE COMPARED WITH SITTING QUIETLY FOR THE SAME DURATION AS A CONTROL. MATERIALS AND METHODS: NINETEEN PARTICIPANTS WITH EXPERIENCE OF SURYABHEDA PRANAYAMA PRACTICE (GROUP MEAN EXPERIENCE +/- STANDARD DEVIATION, 30.2 +/- 22.8 MONTHS) WERE ASSESSED IN 3 SESSIONS ON SEPARATE DAYS. THE SESSIONS WERE (I) SURYABHEDA PRANAYAMA WITH PHYSIOLOGICAL LOCKS OR BREATH RETENTION, (II) SURYABHEDA PRANAYAMA WITHOUT PHYSIOLOGICAL LOCKS OR BREATH RETENTION, AND (III) QUIET SITTING (CONTROL SESSION). THE AXILLARY SURFACE BODY TEMPERATURE WAS MONITORED IN ALL THREE SESSIONS BEFORE (5 MIN), DURING (15 MIN), AND AFTER (5 MIN) THE INTERVENTION. AMBIENT TEMPERATURE AND HUMIDITY IN THE RECORDING CABIN USED FOR TESTING WERE NOTED. FROM THE AMBIENT TEMPERATURE AND HUMIDITY, THE HEAT INDEX WAS DERIVED. STATISTICAL ANALYSIS: REPEATED MEASURES ANALYSES OF VARIANCE WERE PERFORMED TO COMPARE VALUES BEFORE, DURING, AND AFTER THE 3 SESSIONS, USING SPSS VERSION 24.0. RESULTS: THE SURFACE BODY TEMPERATURE INCREASED DURING AND AFTER SURYABHEDA PRANAYAMA WITH PHYSIOLOGICAL LOCKS (P < 0.001; P < 0.001), SURYABHEDA PRANAYAMA WITHOUT PHYSIOLOGICAL LOCKS (P < 0.01; P < 0.001), AND QUIET SITTING (P < 0.001; P < 0.001) COMPARED TO THE RESPECTIVE BEFORE VALUES. CONCLUSION: THE CONTROL (I.E., QUIET SITTING) AND EXPERIMENTAL SESSIONS (I.E., SURYABHEDA WITH LOCKS AND SURYABHEDA WITHOUT LOCKS) SHOWED A COMPARABLE INCREASE IN THE SURFACE BODY TEMPERATURE. HENCE, THE INCREASE IN SURFACE BODY TEMPERATURE DURING AND AFTER EXPERIMENTAL SESSIONS DOES NOT APPEAR TO BE RELATED TO THE PRANAYAMA TECHNIQUES. THE POSSIBLE FACTORS WHICH MAY HAVE CONTRIBUTED TO INCREASED SURFACE BODY TEMPERATURE IN THE CONTROL AND EXPERIMENTAL SESSIONS HAVE BEEN DISCUSSED.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
10   72  49 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
11  695  38 EFFECT OF FOUR VOLUNTARY REGULATED YOGA BREATHING TECHNIQUES ON GRIP STRENGTH. BILATERAL HAND-GRIP STRENGTH WAS STUDIED IN 21 MALE VOLUNTEERS (M AGE = 25.6 YR., SD = 5.2). ALL WERE ASSESSED BEFORE AND AFTER FIVE PRACTICE SESSIONS OF 20 MIN. DURATION: RIGHT-NOSTRIL YOGA BREATHING, LEFT-NOSTRIL YOGA BREATHING, ALTERNATE-NOSTRIL YOGA BREATHING, BREATH AWARENESS, AND A NO-INTERVENTION SESSION. DATA WERE ANALYZED WITH ANALYSES OF VARIANCE AND AN ANALYSIS OF VARIANCE USING THE NO-BREATH AWARENESS CONTROL CONDITION AS A COVARIATE. THERE WERE NO SIGNIFICANT CHANGES. THE LEFT-HAND-GRIP STRENGTH REDUCED AFTER LEFT-NOSTRIL YOGA BREATHING. HOWEVER, FINDINGS WERE NOT CONSIDERED SIGNIFICANT, SO METHODOLOGICAL ISSUES IN YOGA RESEARCH WHICH COULD CONTRIBUTE TO NULL FINDINGS AND EVEN MASK ACTUAL CHANGES WERE DISCUSSED.	2009	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
12 1559  27 LONG-TERM VIHANGAM YOGA MEDITATION AND SCORES ON TESTS OF ATTENTION. ALTHOUGH THE LITERATURE INDICATES THAT MEDITATION HAS BENEFICIAL EFFECTS ON SEVERAL ASPECTS OF HUMAN FUNCTIONING, FEW STUDIES HAVE SPECIFICALLY INVESTIGATED THE EFFECTS OF MEDITATION ON VARIOUS DOMAINS OF ATTENTION. THIS STUDY WAS CONDUCTED TO EXAMINE THE DIFFERENCES IN VARIOUS DOMAINS OF ATTENTION BETWEEN LONG-TERM CONCENTRATIVE MEDITATORS VERSUS MATCHED CONTROLS. 15 PRACTITIONERS OF VIHANGAM YOGA (> 10 YR. EXPERIENCE) WERE ENROLLED IN THE STUDY. CONTROLS MATCHED ON AGE, SEX, AND YEARS OF EDUCATION WERE RECRUITED. BOTH GROUPS WERE ADMINISTERED THE STROOP, TRAIL-MAKING, AND DIGIT SYMBOL SUBSTITUTION TESTS AS WELL AS THE DIGIT FORWARD AND DIGIT BACKWARD TESTS. THE GROUP OF VIHANGAM YOGIS HAD SIGNIFICANTLY BETTER MEAN PERFORMANCE ON ALL TESTS OF ATTENTION. LONG-TERM VIHANGAM YOGA MEDITATION IMPROVES ATTENTION SPAN, PROCESSING SPEED, ATTENTION ALTERNATION ABILITY, AND PERFORMANCE IN INTERFERENCE TESTS.	2010	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
13  830  45 EFFECT OF YOGA ON MENTAL HEALTH: COMPARATIVE STUDY BETWEEN YOUNG AND SENIOR SUBJECTS IN JAPAN. BACKGROUND: JAPAN HAS A LARGE NUMBER OF SENIOR CITIZENS. YOGA CAN BE WISELY APPLIED IN OLD AGE CARE. THERE IS NO ANY AGE RESTRICTION TO PRACTICE YOGA. THE EFFECT MAY DIFFER BY AGE. THERE IS A NEED TO STUDY THE MECHANISM OF ACTION OF YOGA WITH RESPECT TO AGE. AIM: THIS STUDY WAS CONDUCTED IN JAPAN TO FIND THE EFFECT OF YOGA ON MENTAL HEALTH BETWEEN YOUNG AND SENIOR PEOPLE. MATERIALS AND METHODS: TWENTY-FIVE NORMAL HEALTHY VOLUNTEERS OF BOTH SEXES WERE DIVIDED INTO TWO GROUPS ACCORDING TO AGE. FIFTEEN PARTICIPANTS OF THE AGE GROUP BETWEEN 65 TO 75 YEARS AND 10 PARTICIPANTS OF THE AGE GROUP BETWEEN 20 TO 30 YEARS WERE SELECTED. THIS STUDY WAS APPROVED BY THE ETHICAL COMMITTEE OF KAWASAKI UNIVERSITY OF MEDICAL WELFARE. SELECTED INDIVIDUALS WERE SUBJECTED TO 90 MIN OF YOGA CLASSES ONCE OR TWICE A WEEK FOR A MONTH. SALIVARY AMYLASE ACTIVITY WAS ASSESSED BEFORE AND AFTER YOGA PRACTICE. STATE TRAIT ANXIETY INVENTORY (STAI) WAS GIVEN BEFORE YOGA ON THE FIRST DAY AND AFTER ONE MONTH OF PRACTICE TO ASSESS THE CHANGE IN STATE ANXIETY AND TRAIT ANXIETY. RESULTS: SENIOR GROUP - SALIVARY AMYLASE ACTIVITY DECREASED FROM 111.2+/-42.7 TO 83.48+/-39.5 KU/L [AVERAGE+/-STANDARD DEVIATION]. YOUNGER GROUP - SALIVARY AMYLASE ACTIVITY REDUCED FROM 60.74+/-31.8 TO 42.39+/-24 KU/L. SENIOR GROUP - STATE ANXIETY SCORE DECREASED FROM 41.13 +/-8.43 TO 30.8+/-6.49, TRAIT ANXIETY SCORE REDUCED FROM 45.66+/-7.5 TO 40.73+/-8.3. YOUNGER GROUP - STATE ANXIETY SCORE REDUCED FROM 38.7+/-4.8 TO 30.8+/-4.1,TRAIT ANXIETY SCORE REDUCED FROM 46.2+/-7.9 TO 42.9+/-9.1. CHANGES WERE STATISTICALLY SIGNIFICANT WITH P<0.05. CONCLUSION: DECREASE IN SALIVARY AMYLASE ACTIVITY MAY BE DUE TO REDUCTION IN SYMPATHETIC RESPONSE. REDUCTION IN STATE AND TRAIT ANXIETY SCORE SIGNIFIES THAT YOGA HAS BOTH IMMEDIATE AS WELL AS LONG-TERM EFFECT ON ANXIETY REDUCTION. THUS YOGA HELPS TO IMPROVE THE MENTAL HEALTH IN BOTH THE GROUPS.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
14 1762  44 POST TRAUMATIC STRESS SYMPTOMS AND HEART RATE VARIABILITY IN BIHAR FLOOD SURVIVORS FOLLOWING YOGA: A RANDOMIZED CONTROLLED STUDY. BACKGROUND: AN EARLIER STUDY SHOWED THAT A WEEK OF YOGA PRACTICE WAS USEFUL IN STRESS MANAGEMENT AFTER A NATURAL CALAMITY. DUE TO HEAVY RAIN AND A RIFT ON THE BANKS OF THE KOSI RIVER, IN THE STATE OF BIHAR IN NORTH INDIA, THERE WERE FLOODS WITH LOSS OF LIFE AND PROPERTY. A WEEK OF YOGA PRACTICE WAS GIVEN TO THE SURVIVORS A MONTH AFTER THE EVENT AND THE EFFECT WAS ASSESSED. METHODS: TWENTY-TWO VOLUNTEERS (GROUP AVERAGE AGE +/- S.D, 31.5 +/- 7.5 YEARS; ALL OF THEM WERE MALES) WERE RANDOMLY ASSIGNED TO TWO GROUPS, YOGA AND A NON-YOGA WAIT-LIST CONTROL GROUP. THE YOGA GROUP PRACTICED YOGA FOR AN HOUR DAILY WHILE THE CONTROL GROUP CONTINUED WITH THEIR ROUTINE ACTIVITIES. BOTH GROUPS' HEART RATE VARIABILITY, BREATH RATE, AND FOUR SYMPTOMS OF EMOTIONAL DISTRESS USING VISUAL ANALOG SCALES, WERE ASSESSED ON THE FIRST AND EIGHTH DAY OF THE PROGRAM. RESULTS: THERE WAS A SIGNIFICANT DECREASE IN SADNESS IN THE YOGA GROUP (P < 0.05, PAIRED T-TEST, POST DATA COMPARED TO PRE) AND AN INCREASE IN ANXIETY IN THE CONTROL GROUP (P < 0.05, PAIRED T-TEST, POST DATA COMPARED TO PRE). CONCLUSIONS: A WEEK OF YOGA CAN REDUCE FEELINGS OF SADNESS AND POSSIBLY PREVENT AN INCREASE IN ANXIETY IN FLOOD SURVIVORS A MONTH AFTER THE CALAMITY.

15 2085  40 THE EFFECT OF LONG TERM COMBINED YOGA PRACTICE ON THE BASAL METABOLIC RATE OF HEALTHY ADULTS. BACKGROUND: DIFFERENT PROCEDURES PRACTICED IN YOGA HAVE STIMULATORY OR INHIBITORY EFFECTS ON THE BASAL METABOLIC RATE WHEN STUDIED ACUTELY. IN DAILY LIFE HOWEVER, THESE PROCEDURES ARE USUALLY PRACTICED IN COMBINATION. THE PURPOSE OF THE PRESENT STUDY WAS TO INVESTIGATE THE NET CHANGE IN THE BASAL METABOLIC RATE (BMR) OF INDIVIDUALS ACTIVELY ENGAGING IN A COMBINATION OF YOGA PRACTICES (ASANA OR YOGIC POSTURES, MEDITATION AND PRANAYAMA OR BREATHING EXERCISES) FOR A MINIMUM PERIOD OF SIX MONTHS, AT A RESIDENTIAL YOGA EDUCATION AND RESEARCH CENTER AT BANGALORE. METHODS: THE MEASURED BMR OF INDIVIDUALS PRACTICING YOGA THROUGH A COMBINATION OF PRACTICES WAS COMPARED WITH THAT OF CONTROL SUBJECTS WHO DID NOT PRACTICE YOGA BUT LED SIMILAR LIFESTYLES. RESULTS: THE BMR OF THE YOGA PRACTITIONERS WAS SIGNIFICANTLY LOWER THAN THAT OF THE NON-YOGA GROUP, AND WAS LOWER BY ABOUT 13 % WHEN ADJUSTED FOR BODY WEIGHT (P < 0.001). THIS DIFFERENCE PERSISTED WHEN THE GROUPS WERE STRATIFIED BY GENDER; HOWEVER, THE DIFFERENCE IN BMR ADJUSTED FOR BODY WEIGHT WAS GREATER IN WOMEN THAN MEN (ABOUT 8 AND 18% RESPECTIVELY). IN ADDITION, THE MEAN BMR OF THE YOGA GROUP WAS SIGNIFICANTLY LOWER THAN THEIR PREDICTED VALUES, WHILE THE MEAN BMR OF NON-YOGA GROUP WAS COMPARABLE WITH THEIR PREDICTED VALUES DERIVED FROM 1985 WHO/FAO/UNU PREDICTIVE EQUATIONS. CONCLUSION: THIS STUDY SHOWS THAT THERE IS A SIGNIFICANTLY REDUCED BMR, PROBABLY LINKED TO REDUCED AROUSAL, WITH THE LONG TERM PRACTICE OF YOGA USING A COMBINATION OF STIMULATORY AND INHIBITORY YOGIC PRACTICES.	2006	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
16 1355  33 IMMEDIATE EFFECT OF TWO YOGA-BASED RELAXATION TECHNIQUES ON ATTENTION IN CHILDREN. AIMS: TO INVESTIGATE THE EFFECT OF TWO YOGA-BASED RELAXATION TECHNIQUES, NAMELY, CYCLIC MEDITATION (CM) AND SUPINE REST (SR), USING THE SIX LETTER CANCELLATION TASK (SLCT). MATERIALS AND METHODS: THE SUBJECTS CONSISTED OF 208 SCHOOL STUDENTS, (132 BOYS, 76 GIRLS) IN THE AGE RANGE OF 13 - 16 YEARS. THE SUBJECTS WERE ASSESSED ON SLCT BEFORE AND IMMEDIATELY AFTER BOTH YOGA-BASED RELAXATION TECHNIQUES. RESULTS: AFTER BOTH PRACTICES, THE TOTAL AND NET SCORES WERE SIGNIFICANTLY INCREASED, ALTHOUGH THE MAGNITUDE OF CHANGE WAS MORE AFTER CM THAN AFTER SR IN THE NET SCORES (14.5 VERSUS 11.31%). THE NET SCORE CHANGE IN THE CM SESSION WAS SIGNIFICANTLY LARGER THAN THE CHANGE IN THE SR, WHEREAS, THERE WAS NO SIGNIFICANT CHANGE IN THE WRONG CANCELLATION SCORE. AFTER EITHER PRACTICE, THE TOTAL AND NET SCORES WERE SIGNIFICANTLY INCREASED, IRRESPECTIVE OF GENDER AND AGE. CONCLUSIONS: BOTH CM AND SR LED TO IMPROVEMENT IN PERFORMANCE, AS ASSESSED BY SLCT, BUT THE CHANGE CAUSED BY CM WAS LARGER THAN SR.	2010	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
17  768  47 EFFECT OF TWO YOGA-BASED RELAXATION TECHNIQUES ON MEMORY SCORES AND STATE ANXIETY. BACKGROUND: A YOGA PRACTICE INVOLVING CYCLES OF YOGA POSTURES AND SUPINE REST (CALLED CYCLIC MEDITATION) WAS PREVIOUSLY SHOWN TO IMPROVE PERFORMANCE IN ATTENTION TASKS MORE THAN RELAXATION IN THE CORPSE POSTURE (SHAVASANA). THIS WAS ASCRIBED TO REDUCED ANXIETY, THOUGH THIS WAS NOT ASSESSED. METHODS: IN FIFTY-SEVEN MALE VOLUNTEERS (GROUP AVERAGE AGE +/- S.D., 26.6 +/- 4.5 YEARS) THE IMMEDIATE EFFECT OF TWO YOGA RELAXATION TECHNIQUES WAS STUDIED ON MEMORY AND STATE ANXIETY. ALL PARTICIPANTS WERE ASSESSED BEFORE AND AFTER (I) CYCLIC MEDITATION (CM) PRACTICED FOR 22:30 MINUTES ON ONE DAY AND (II) AN EQUAL DURATION OF SUPINE REST (SR) OR THE CORPSE POSTURE (SHAVASANA), ON ANOTHER DAY. SECTIONS OF THE WECHSLER MEMORY SCALE (WMS) WERE USED TO ASSESS; (I) ATTENTION AND CONCENTRATION (DIGIT SPAN FORWARD AND BACKWARD), AND (II) ASSOCIATE LEARNING. STATE ANXIETY WAS ASSESSED USING SPIELBERGER'S STATE-TRAIT ANXIETY INVENTORY (STAI). RESULTS: THERE WAS A SIGNIFICANT IMPROVEMENT IN THE SCORES OF ALL SECTIONS OF THE WMS STUDIED AFTER BOTH CM AND SR, BUT, THE MAGNITUDE OF CHANGE WAS MORE AFTER CM COMPARED TO AFTER SR. THE STATE ANXIETY SCORES DECREASED AFTER BOTH CM AND SR, WITH A GREATER MAGNITUDE OF DECREASE AFTER CM. THERE WAS NO CORRELATION BETWEEN PERCENTAGE CHANGE IN MEMORY SCORES AND STATE ANXIETY FOR EITHER SESSION. CONCLUSION: A CYCLICAL COMBINATION OF YOGA POSTURES AND SUPINE REST IN CM IMPROVED MEMORY SCORES IMMEDIATELY AFTER THE PRACTICE AND DECREASED STATE ANXIETY MORE THAN REST IN A CLASSICAL YOGA RELAXATION POSTURE (SHAVASANA).	2009	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
18  850  30 EFFECT OF YOGA ON SHORT-TERM HEART RATE VARIABILITY MEASURE AS A STRESS INDEX IN SUBJUNIOR CYCLISTS: A PILOT STUDY. SUBJUNIOR ATHLETES EXPERIENCE MENTAL STRESS DUE TO PRESSURE FROM THE COACH, TEACHERS AND PARENTS FOR BETTER PERFORMANCE. STRESS, IF REMAINS FOR LONGER PERIOD AND NOT MANAGED APPROPRIATELY CAN LEADS TO NEGATIVE PHYSICAL, MENTAL AND COGNITIVE IMPACT ON CHILDREN. THE PRESENT STUDY WAS AIMED TO EVALUATE THE EFFECT OF INTEGRATED YOGA MODULE ON HEART RATE VARIABILITY (HRV) MEASURE AS A STRESS INDEX IN SUBJUNIOR CYCLISTS. FAST FURRIER TRANSFORM TECHNIQUE OF FREQUENCY DOMAIN METHOD WAS USED FOR THE ANALYSIS OF HRV. WE HAVE FOUND A SIGNIFICANT INCREASE IN HIGH FREQUENCY (HF) COMPONENT BY 14.64% (P < 0.05) AND DECREASE IN THE LOW FREQUENCY COMPONENT (LF) OF HRV SPECTRUM BY 5.52% (P < 0.05) AND A DECREASE IN LF/HF RATIO BY 19.63% (P < 0.01) IN YOGA GROUP. IN THE CONTROL GROUP, THERE WAS DECREASE IN THE HF COMPONENT AND, NO SIGNIFICANT DIFFERENCE IN THE LF COMPONENT OF HRV SPECTRUM AND LF/HF RATIO. THE RESULTS SHOW THAT YOGA PRACTICE DECREASES SYMPATHETIC ACTIVITY AND CAUSES A SHIFT IN THE AUTONOMIC BALANCE TOWARDS PARASYMPATHETIC DOMINANCE INDICATING A REDUCTION IN STRESS. IN CONCLUSION, YOGA PRACTICE HELPS TO REDUCE STRESS BY OPTIMIZING THE AUTONOMIC FUNCTIONS. SO, IT IS SUGGESTED TO INCORPORATE YOGA MODULE AS A REGULAR FEATURE TO KEEP SUBJUNIOR ATHLETES BOTH MENTALLY AND PHYSICALLY FIT.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
19  678  30 EFFECT OF A YOGA PRACTICE SESSION AND A YOGA THEORY SESSION ON STATE ANXIETY. YOGA TECHNIQUES PRACTICED FOR VARYING DURATIONS HAVE BEEN SHOWN TO REDUCE STATE ANXIETY. IN THIS STUDY, THERE WERE 300 NAIVE-TO-YOGA PERSONS OF BOTH SEXES WHO WERE ATTENDING A YOGA THERAPY CENTER IN NORTH INDIA FOR STRESS RELIEF AS DAY VISITORS AND WERE NOT RESIDING AT THE CENTER. THEY WERE ASSIGNED TO TWO GROUPS, YOGA PRACTICE AND YOGA THEORY, AND THEIR STATE ANXIETY WAS ASSESSED BEFORE AND AFTER A 2-HR. YOGA SESSION. A SIGNIFICANT REDUCTION IN SCORES ON STATE ANXIETY WAS FOUND IN THE YOGA PRACTICE GROUP (14.7% DECREASE), AS WELL AS IN THE YOGA THEORY GROUP (3.4% DECREASE). THE DIFFERENCE IN SCORES FOLLOWING THE SESSIONS WAS STATISTICALLY SIGNIFICANT. HENCE, YOGA PRACTICE AS WELL AS LEARNING ABOUT THEORETICAL ASPECTS OF YOGA APPEAR TO REDUCE STATE ANXIETY, WITH A GREATER REDUCTION FOLLOWING YOGA PRACTICE.	2009	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
20  760  39 EFFECT OF SUDARSANKRIYA YOGA PRACTICES ON P300 AMPLITUDE AND LATENCY. THE COGNITIVE ABILITY WHICH WAS PERCEIVED AS A CONSTANT TRAIT, IS NOW UNDERSTOOD TO BE UPGRADED BY ADAPTIVE AND EXTENDED TRAINING. YOGA PRACTICES ARE KNOWN TO SHARPEN THE INTELLECT AND ENHANCE CONCENTRATION. IN THE INITIAL PERIOD OF PRACTICING YOGA AS AN ALTERNATIVE/SUPPORTING TOOL TO MEDICAL LINE OF TREATMENT, IT IS ESSENTIAL TO INVESTIGATE EFFECT OF YOGA ON COGNITIVE ABILITY USING OBJECTIVE METHOD, IN ORDER TO ESTABLISH EVIDENCES. HENCE, AIM OF THIS STUDY WAS TO EXPLORE THE EFFECT OF REGULAR PRACTICE OF SUDARSANKRIYA YOGA ON AUDITORY EVENT RELATED POTENTIAL (P300) BY RECORDING AND COMPARING PEAK LATENCY AND AMPLITUDE. THE PARTICIPANTS WERE DIVIDED INTO THREE GROUPS WITH GROUP I AND GROUP II PARTICIPANTS PRACTICING SUDARSANKRIYA YOGA FOR MORE THAN 36 MONTHS AND LESS THAN 36 MONTHS RESPECTIVELY. GROUP III WERE NON-PRACTITIONERS WITH NO PRIOR PRACTICE OF ANY FORM OF YOGA. TWENTY PARTICIPANTS IN EACH GROUP WITH A TOTAL OF 60 PARTICIPANTS BETWEEN 40 TO 65 YEARS OF AGE WERE RECRUITED FOR THE STUDY. RESULTS REVEALED A SIGNIFICANT DIFFERENCE FOR MEAN LATENCY AND AMPLITUDE BETWEEN THREE GROUPS. FINDINGS OF THE CURRENT STUDY SUGGEST THAT SUDARSANKRIYA YOGA PRACTICES SLOWS DOWN THE PROCESS OF AGING EFFECT OR MAINTAINS ON COGNITIVE ABILITY IN ADULTS.	2021
