1 1692 116 OXYGEN CONSUMPTION AND RESPIRATION FOLLOWING TWO YOGA RELAXATION TECHNIQUES. THE PRESENT STUDY WAS CONDUCTED TO EVALUATE A STATEMENT IN ANCIENT YOGA TEXTS THAT SUGGESTS THAT A COMBINATION OF BOTH "CALMING" AND "STIMULATING" MEASURES MAY BE ESPECIALLY HELPFUL IN REACHING A STATE OF MENTAL EQUILIBRIUM. TWO YOGA PRACTICES, ONE COMBINING "CALMING AND STIMULATING" MEASURES (CYCLIC MEDITATION) AND THE OTHER, A "CALMING" TECHNIQUE (SHAVASAN), WERE COMPARED. THE OXYGEN CONSUMPTION, BREATH RATE, AND BREATH VOLUME OF 40 MALE VOLUNTEERS (GROUP MEAN +/- SD, 27.0 +/- 5.7 YEARS) WERE ASSESSED BEFORE AND AFTER SESSIONS OF CYCLIC MEDITATION (CM) AND BEFORE AND AFTER SESSIONS OF SHAVASAN (SH). THE 2 SESSIONS (CM, SH) WERE 1 DAY APART. CYCLIC MEDITATION INCLUDES THE PRACTICE OF YOGA POSTURES INTERSPERSED WITH PERIODS OF SUPINE RELAXATION. DURING SH THE SUBJECT LIES IN A SUPINE POSITION THROUGHOUT THE PRACTICE. THERE WAS A SIGNIFICANT DECREASE IN THE AMOUNT OF OXYGEN CONSUMED AND IN BREATH RATE AND AN INCREASE IN BREATH VOLUME AFTER BOTH TYPES OF SESSIONS (2-FACTOR ANOVA, PAIRED T TEST). HOWEVER, THE MAGNITUDE OF CHANGE ON ALL 3 MEASURES WAS GREATER AFTER CM: (1) OXYGEN CONSUMPTION DECREASED 32.1% AFTER CM COMPARED WITH 10.1% AFTER SH; (2) BREATH RATE DECREASED 18.0% AFTER CM AND 15.2% AFTER SH; AND (3) BREATH VOLUME INCREASED 28.8% AFTER CM AND 15.9% AFTER SH. THESE RESULTS SUPPORT THE IDEA THAT A COMBINATION OF YOGA POSTURES INTERSPERSED WITH RELAXATION REDUCES AROUSAL MORE THAN RELAXATION ALONE DOES.	2000	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
2 1691  68 OXYGEN CONSUMPTION AND RESPIRATION DURING AND AFTER TWO YOGA RELAXATION TECHNIQUES. CYCLIC MEDITATION (CM) IS A TECHNIQUE WHICH COMBINES "STIMULATING" AND "CALMING" PRACTICES, BASED ON A STATEMENT IN ANCIENT YOGA TEXTS SUGGESTING THAT SUCH A COMBINATION MAY BE ESPECIALLY HELPFUL TO REACH A STATE OF MENTAL EQUILIBRIUM. THE OXYGEN CONSUMPTION, BREATH RATE AND BREATH VOLUME OF 50 MALE VOLUNTEERS (GROUP MEAN AGE+/-SD, 27+/-6.3 YEARS) WERE ASSESSED BEFORE, DURING, AND AFTER SESSIONS OF CM AND SESSIONS OF SUPINE REST IN THE CORPSE POSTURE (SHAVASANA, SH). THE SESSIONS WERE ONE DAY APART AND THE ORDER WAS ALTERNATED. THE OXYGEN CONSUMPTION, BREATH RATE AND BREATH VOLUME INCREASED DURING THE "STIMULATING" PRACTICES OF CM, RETURNED TO THE BASELINE DURING THE "CALMING" PRACTICES, AND THE OXYGEN CONSUMPTION DECREASED BY 19.3 PERCENT BELOW BASELINE VALUES AFTER CM. DURING THE SH SESSION THE OXYGEN CONSUMPTION, BREATH RATE AND BREATH VOLUME REDUCED; HOWEVER THE DECREASE IN OXYGEN CONSUMPTION AFTER SH WAS LESS THAN AFTER CM (I.E., 4.8 PERCENT). THE RESULTS SUPPORT THE IDEA THAT A COMBINATION OF YOGA POSTURES WITH SUPINE REST (IN CM) REDUCES THE OXYGEN CONSUMPTION MORE THAN RESTING SUPINE ALONE DOES.	2006	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
3  768  45 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
4 2863  43 YOGA-BASED GUIDED RELAXATION REDUCES SYMPATHETIC ACTIVITY JUDGED FROM BASELINE LEVELS. 35 MALE VOLUNTEERS WHOSE AGES RANGED FROM 20 TO 46 YEARS WERE STUDIED IN TWO SESSIONS OF YOGA-BASED GUIDED RELAXATION AND SUPINE REST. ASSESSMENTS OF AUTONOMIC VARIABLES WERE MADE FOR 15 SUBJECTS, BEFORE, DURING, AND AFTER THE PRACTICES, WHEREAS OXYGEN CONSUMPTION AND BREATH VOLUME WERE RECORDED FOR 25 SUBJECTS BEFORE AND AFTER BOTH TYPES OF RELAXATION. A SIGNIFICANT DECREASE IN OXYGEN CONSUMPTION AND INCREASE IN BREATH VOLUME WERE RECORDED AFTER GUIDED RELAXATION (PAIRED T TEST). THERE WERE COMPARABLE REDUCTIONS IN HEART RATE AND SKIN CONDUCTANCE DURING BOTH TYPES OF RELAXATION. DURING GUIDED RELAXATION THE POWER OF THE LOW FREQUENCY COMPONENT OF THE HEART-RATE VARIABILITY SPECTRUM REDUCED, WHEREAS THE POWER OF THE HIGH FREQUENCY COMPONENT INCREASED, SUGGESTING REDUCED SYMPATHETIC ACTIVITY. ALSO, SUBJECTS WITH A BASELINE RATIO OF LF/HF > 0.5 SHOWED A SIGNIFICANT DECREASE IN THE RATIO AFTER GUIDED RELAXATION, WHILE SUBJECTS WITH A RATIO < OR = 0.5 AT BASELINE SHOWED NO SUCH CHANGE. THE RESULTS SUGGEST THAT SYMPATHETIC ACTIVITY DECREASED AFTER GUIDED RELAXATION BASED ON YOGA, DEPENDING ON THE BASELINE LEVELS.	2002	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
5  785  40 EFFECT OF YOGA BASED TECHNIQUES ON STRESS AND HEALTH INDICES USING ELECTRO PHOTONIC IMAGING TECHNIQUE IN MANAGERS. BACKGROUND: MEDITATION TECHNIQUES ARE KNOWN TO ELICIT RELAXATION RESPONSE IN WHICH MOVING MEDITATION WHICH COMBINES THE PRACTICE OF YOGA POSTURES AND GUIDED RELAXATION IS KNOWN AS CYCLIC MEDITATION REPORTED HELPFUL IN REDUCING THE SYMPATHETIC AROUSAL AND IMPROVING HEALTH OF PRACTITIONERS. OBJECTIVES: THE OBJECTIVE OF THIS STUDY WAS TO INVESTIGATE THE EFFECT OF CYCLIC MEDITATION ON STRESS AND HEALTH INDICES IN MANAGERS AS MEASURED BY ELECTRO PHOTONIC IMAGING (EPI) TECHNIQUE. MATERIALS AND METHODS: EPI TECHNIQUE WAS USED TO ASSESS PARTICIPANTS BEFORE AND AFTER 35 MIN OF CYCLIC MEDITATION (CM) AND EQUAL DURATION OF SUPINE REST (SR) SESSION. A TOTAL OF SIXTY SIX MALE MANAGERS, AGE RANGES FROM 35 TO 60 YEARS (MEAN +/- SD 53.97 +/- 5.96) WERE INCLUDED IN THE STUDY. EPI PARAMETERS, INCLUDING ACTIVATION COEFFICIENT, INTEGRAL AREA LEFT AND RIGHT AND INTEGRAL ENTROPY, LEFT AND RIGHT WERE TAKEN FOR STATISTICAL ANALYSES. RESULTS: CYCLIC MEDITATION HAS PRODUCED A HIGHLY SIGNIFICANT REDUCTION IN STRESS LEVEL, WHEREAS THIS REDUCTION WAS NOT FOUND SIGNIFICANT WITHIN SR GROUP. THERE WAS A SIGNIFICANT IMPROVEMENT IN HEALTH INDEX 'INTEGRAL AREA' VALUES IN BOTH LEFT AND RIGHT SIDES WITHIN THE CM GROUP WHILE ONLY IA RIGHT SIDE SHOWED A SIGNIFICANT IMPROVEMENT WITHIN THE CM GROUP. THE INTEGRAL ENTROPY VALUE RIGHT SIDE DECREASED SIGNIFICANTLY WITHIN THE CM GROUP, WHEREAS IE LEFT WAS FOUND DETERIORATED WITHIN THE SR GROUP. MOREOVER, ONLY IE LEFT SIDE HAS SHOWN A SIGNIFICANT DIFFERENCE BETWEEN THE GROUPS. CONCLUSION: THE INVESTIGATIONS IN THIS STUDY SUGGEST THAT CYCLIC MEDITATION PRACTICE REDUCES STRESS AND IMPROVES PSYCHOSOMATIC HEALTH INDICES MORE EFFECTIVELY THAN SUPINE REST IN MANAGERS.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
6 1357  36 IMMEDIATE EFFECT OF TWO YOGA-BASED RELAXATION TECHNIQUES ON PERFORMANCE IN A LETTER-CANCELLATION TASK. THE PERFORMANCE IN A SIX-LETTER CANCELLATION TASK WAS ASSESSED WITH 69 MALE VOLUNTEERS, AGES 18 TO 48 YEARS, IMMEDIATELY BEFORE AND AFTER TWO YOGA-BASED RELAXATION TECHNIQUES AND A CONTROL SESSION OF EQUAL DURATION. THE TECHNIQUES WERE CYCLIC MEDITATION AND SUPINE REST. CYCLIC MEDITATION CONSISTS OF ALTERNATING CYCLES OF YOGA POSTURES AND SUPINE REST. AFTER BOTH PRACTICES, THE NET SCORES WERE SIGNIFICANTLY HIGHER, ALTHOUGH THE MAGNITUDE OF CHANGE WAS MORE AFTER CYCLIC MEDITATION THAN AFTER SUPINE REST (24.9% VERSUS 13.6%). THERE WAS REDUCTION IN SCORES FOR WRONG CANCELLATIONS AFTER CYCLIC MEDITATION AND NOT AFTER SUPINE REST. THE CONTROL GROUP SHOWED NO CHANGE. THE RESULTS SUGGEST THAT CYCLIC MEDITATION BRINGS ABOUT A GREATER IMPROVEMENT IN PERFORMANCE IN THIS TASK, WHICH REQUIRES SELECTIVE ATTENTION, CONCENTRATION, VISUAL SCANNING ABILITIES, AND A REPETITIVE MOTOR RESPONSE.	2007	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
7  306  36 AN EVALUATION OF THE ABILITY TO VOLUNTARILY REDUCE THE HEART RATE AFTER A MONTH OF YOGA PRACTICE. THE STUDY AIMED AT DETERMINING WHETHER NOVICES TO YOGA WOULD BE ABLE TO REDUCE THEIR HEART RATE VOLUNTARILY AND WHETHER THE MAGNITUDE OF REDUCTION WOULD BE MORE AFTER 30 DAYS OF YOGA TRAINING. TWO GROUPS (YOGA AND CONTROL, N = 12 EACH) WERE ASSESSED ON DAY 1 AND ON DAY 30. DURING THE INTERVENING 30 DAYS, THE YOGA GROUP RECEIVED TRAINING IN YOGA TECHNIQUES WHILE THE CONTROL GROUP CARRIED ON WITH THEIR ROUTINE. AT EACH ASSESSMENT THE BASELINE HEART RATE WAS RECORDED FOR ONE MINUTE, THIS WAS FOLLOWED BY A SIX-MINUTE PERIOD DURING WHICH PARTICIPANTS WERE ASKED TO ATTEMPT TO VOLUNTARILY REDUCE THEIR HEART RATE, USING ANY STRATEGY. BOTH THE BASELINE HEART RATE AND THE LOWEST HEART RATE ACHIEVED VOLUNTARILY DURING THE SIX-MINUTE PERIOD WERE SIGNIFICANTLY LOWER IN THE YOGA GROUP ON DAY 30 COMPARED TO DAY 1 BY A GROUP AVERAGE OF 10.7 BEATS PER MINUTE (I.E., BPM) AND 6.8 BPM, RESPECTIVELY (P < .05, WILCOXON PAIRED SIGNED RANKS TEST). IN CONTRAST, THERE WAS NO SIGNIFICANT CHANGE IN EITHER THE BASELINE HEART RATE OR THE LOWEST HEART RATE ACHIEVED VOLUNTARILY IN THE CONTROL GROUP ON DAY 30 COMPARED TO DAY 1. THE RESULTS SUGGEST THAT YOGA TRAINING CAN ENABLE PRACTITIONERS TO USE THEIR OWN STRATEGIES TO REDUCE THE HEART RATE, WHICH HAS POSSIBLE THERAPEUTIC APPLICATIONS.	2004	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
8  523  32 COMPARISON OF CHANGES IN AUTONOMIC AND RESPIRATORY PARAMETERS OF GIRLS AFTER YOGA AND GAMES AT A COMMUNITY HOME. THE HEART RATE, BREATHING RATE, AND SKIN RESISTANCE WERE RECORDED FOR 20 COMMUNITY HOME GIRLS (HOME GROUP) AND FOR 20 AGE-MATCHED GIRLS FROM A REGULAR SCHOOL (SCHOOL GROUP). THE FORMER GROUP HAD A SIGNIFICANTLY HIGHER RATE OF BREATHING AND A MORE IRREGULAR BREATH PATTERN KNOWN TO CORRELATE WITH HIGH FEAR AND ANXIETY, THAN THE SCHOOL GROUP. SKIN RESISTANCE WAS SIGNIFICANTLY LOWER IN THE SCHOOL GROUP, WHICH MAY SUGGEST GREATER AROUSAL, 28 GIRLS OF THE HOME GROUP FORMED 14 PAIRS, MATCHED FOR AGE AND DURATION OF STAY IN THE HOME. SUBJECTS OF A PAIR WERE RANDOMLY ASSIGNED TO EITHER YOGA OR GAMES GROUPS. FOR THE FORMER EMPHASIS WAS ON RELAXATION AND AWARENESS, WHEREAS FOR THE LATTER INCREASING PHYSICAL ACTIVITY WAS EMPHASIZED. AT THE END OF AN HOUR DAILY FOR SIX MONTHS BOTH GROUPS SHOWED A SIGNIFICANT DECREASE IN THE RESTING HEART RATE RELATIVE TO INITIAL VALUES (WILCOXON PAIRED-SAMPLE REST), AND THE YOGA GROUP SHOWED A SIGNIFICANT DECREASE IN BREATH RATE, WHICH APPEARED MORE REGULAR BUT NO SIGNIFICANT INCREASE IN THE SKIN RESISTANCE. THESE RESULTS SUGGEST THAT A YOGA PROGRAM WHICH INCLUDES RELAXATION, AWARENESS, AND GRADED PHYSICAL ACTIVITY IS A USEFUL ADDITION TO THE ROUTINE OF COMMUNITY HOME CHILDREN.	1997	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
9  525  30 COMPARISON OF EFFECTS OF YOGA & PHYSICAL EXERCISE IN ATHLETES. THE EFFECT OF PRANAYAMA A CONTROLLED BREATHING PRACTICE, ON EXERCISE TESTS WAS STUDIED IN ATHLETES IN TWO PHASES; SUB-MAXIMAL AND MAXIMAL EXERCISE TESTS. AT THE END OF PHASE I (ONE YEAR) BOTH THE GROUPS (CONTROL AND EXPERIMENTAL) ACHIEVED SIGNIFICANTLY HIGHER WORK RATE AND REDUCTION IN OXYGEN CONSUMPTION PER UNIT WORK. THERE WAS A SIGNIFICANT REDUCTION IN BLOOD LACTATE AND AN INCREASE IN P/L RATIO IN THE EXPERIMENTAL GROUP, AT REST. AT THE END OF PHASE II (TWO YEARS), THE OXYGEN CONSUMPTION PER UNIT WORK WAS FOUND TO BE SIGNIFICANTLY REDUCED AND THE WORK RATE SIGNIFICANTLY INCREASED IN THE EXPERIMENTAL GROUP. BLOOD LACTATE DECREASED SIGNIFICANTLY AT REST IN THE EXPERIMENTAL GROUP ONLY. PYRUVATE AND PYRUVATE-LACTATE RATIO INCREASED SIGNIFICANTLY IN BOTH THE GROUPS AFTER EXERCISE AND AT REST IN THE EXPERIMENTAL GROUP. THE RESULTS IN BOTH PHASES SHOWED THAT THE SUBJECTS WHO PRACTISED PRANAYAMA COULD ACHIEVE HIGHER WORK RATES WITH REDUCED OXYGEN CONSUMPTION PER UNIT WORK AND WITHOUT INCREASE IN BLOOD LACTATE LEVELS. THE BLOOD LACTATE LEVELS WERE SIGNIFICANTLY LOW AT REST.	1994	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
10 2364  31 VOLUNTARY HEART RATE REDUCTION FOLLOWING YOGA USING DIFFERENT STRATEGIES. BACKGROUND/AIMS: ONE MONTH OF YOGA TRAINING HAS BEEN SHOWN TO REDUCE THE PULSE RATE VOLUNTARILY WITHOUT USING EXTERNAL CUES. HENCE, THE PRESENT STUDY WAS DESIGNED TO UNDERSTAND THE STRATEGIES USED BY YOGA PRACTITIONERS AND AUTONOMIC CHANGES ASSOCIATED WITH VOLUNTARY HEART RATE REDUCTION. MATERIALS AND METHODS: FIFTY VOLUNTEERS (GROUP MEAN AGE +/- S.D., 25.4 +/- 4.8 YEARS; 25 MALES) WERE ASSESSED IN TWO TRIALS ON SEPARATE DAYS. EACH TRIAL WAS FOR 12 MINUTES, WITH A 'PRE' STATE AND 'DURING' STATE OF 6 MINUTES EACH. FOR BOTH TRIALS THE 'PRE' STATE WAS RELAXATION WITH EYES CLOSED. IN THE 'DURING' STATE OF TRIAL I, SUBJECTS WERE ASKED TO VOLUNTARILY REDUCE THEIR HEART RATE USING A STRATEGY OF THEIR CHOICE. FROM THEIR RESPONSES TO SPECIFIC QUESTIONS IT WAS DETERMINED THAT 22 OUT OF 50 PERSONS USED BREATH REGULATION AS A STRATEGY. HENCE, IN THE 'DURING' STATE OF TRIAL II, SUBJECTS WERE ASKED TO VOLUNTARILY REDUCE THEIR HEART RATE BY BREATH REGULATION. RESULTS: IN THE FIRST TRIAL, THE HEART RATE WAS REDUCED BY AN AVERAGE OF 19.6 BEATS PER MINUTE AND IN THE SECOND TRIAL (WITH BREATH REGULATION EXCLUSIVELY) AN AVERAGE DECREASE OF 22.2 BEATS PER MINUTE WAS ACHIEVED. CONCLUSIONS: HENCE, THE STRATEGY USED DID NOT MARKEDLY ALTER THE OUTCOME.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
11  868  41 EFFECT OF YOGA RELAXATION TECHNIQUES ON PERFORMANCE OF DIGIT-LETTER SUBSTITUTION TASK BY TEENAGERS. BACKGROUND/AIMS: MEMORY AND SELECTIVE ATTENTION ARE IMPORTANT SKILLS FOR ACADEMIC AND PROFESSIONAL PERFORMANCE. TECHNIQUES TO IMPROVE THESE SKILLS ARE NOT TAUGHT EITHER IN EDUCATION OR COMPANY TRAINING COURSES. ANY SYSTEM WHICH CAN SYSTEMATICALLY IMPROVE THESE SKILLS WILL BE OF VALUE IN SCHOOLS, UNIVERSITIES, AND WORKPLACES. AIMS: TO INVESTIGATE POSSIBLE IMPROVEMENTS IN MEMORY AND SELECTIVE ATTENTION, AS MEASURED BY THE DIGIT-LETTER SUBSTITUTION TASK (DLST), DUE TO PRACTICE OF CYCLIC MEDITATION (CM), A YOGA RELAXATION TECHNIQUE, AS COMPARED TO SUPINE REST (SR). MATERIALS AND METHODS: SUBJECTS CONSISTED OF 253 SCHOOL STUDENTS, 156 BOYS, 97 GIRLS, IN THE AGE RANGE 13-16 YEARS, WHO WERE ATTENDING A 10-DAY YOGA TRAINING COURSE DURING SUMMER VACATION. THE SELECTED SUBJECTS HAD ENGLISH AS THEIR MEDIUM OF INSTRUCTION IN SCHOOL AND THEY ACTED AS THEIR OWN CONTROLS. THEY WERE ALLOCATED TO TWO GROUPS, AND TESTED ON THE DLST, IMMEDIATELY BEFORE AND AFTER 22.5 MINUTES PRACTICE OF CM ON ONE DAY, AND IMMEDIATELY BEFORE AND AFTER AN EQUAL PERIOD OF SR ON THE OTHER DAY. THE FIRST GROUP PERFORMED CM ON DAY 9 AND SR ON DAY 10. FOR THE SECOND GROUP, THE ORDER WAS REVERSED. RESULTS: WITHIN EACH GROUP PRE-POST TEST DIFFERENCES WERE SIGNIFICANT FOR BOTH THE RELAXATION TECHNIQUES. THE MAGNITUDE OF NET SCORE IMPROVEMENT WAS GREATER AFTER SR (7.85%) COMPARED TO CM (3.95%). SIGNIFICANCE LEVELS WERE P < 0.4 X 10(-9)FOR SR AND P < 0.1 X 10(-3) FOR CM. THE NUMBER OF WRONG ATTEMPTS ALSO INCREASED SIGNIFICANTLY ON BOTH INTERVENTIONS, EVEN AFTER REMOVING TWO OUTLIER DATA POINTS ON DAY 1 IN THE SR GROUP. CONCLUSIONS: BOTH CM AND SR LEAD TO IMPROVEMENT IN PERFORMANCE ON THE DLST. HOWEVER, THESE RELAXATION TECHNIQUES LEAD TO MORE WRONG CANCELLATION ERRORS.	2009	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
12 1835  23 PSYCHOPHYSIOLOGICAL CHANGES AT THE TIME OF EXAMINATION IN MEDICAL STUDENTS BEFORE AND AFTER THE PRACTICE OF YOGA AND RELAXATION. THE EFFECT OF YOGA AND RELAXATION CHANGES IN PSYCHOPHYSIOLOGICAL PARAMETERS IN RESPONSE TO THE STRESS OF EXAMINATION IN 75 MEDICAL STUDENTS WAS STUDIED. INITIALLY FIVE PARAMETERS (ANXIETY LEVEL, HEART RATE, BLOOD PRESSURE, GALVANIC SKIN RESISTANCE AND CHOICE REACTION TIME) WERE RECORDED, A MONTH BEFORE THE EXAMINATION AND ON THE DAY OF EXAMINATION. STUDENTS WERE THEN RANDOMLY DIVIDED INTO 3 GROUP OF 25 EACH. ONE GROUP PRACTICED YOGA (GROUP- Y), AND ANOTHER GROUP PRACTICED RELAXATION (GROUP-R) REGULARLY FOR THREE MONTHS. THE THIRD GROUP WAS CONTROL GROUP (GROUP-C). ALL THE PARAMETERS WERE RECORDED AFTER THE CHANGES IN ANXIETY LEVEL, HEART RATE, BLOOD PRESSURE, AND GALVANIC SKIN RESISTANCE IN RESPONSE TO STRESS OF EXAMINATION WERE SIGNIFICANTLY ATTENUATED AND THERE WAS SIGNIFICANT IMPROVEMENT IN CHOICE REACTION TIME IN GROUP-Y AND GROUP-R AS COMPARED TO GROUP-C AFTER YOGA AND RELAXATION.	1998	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
13  436  28 CARDIORESPIRATORY AND METABOLIC CHANGES DURING YOGA SESSIONS: THE EFFECTS OF RESPIRATORY EXERCISES AND MEDITATION PRACTICES. THE NOVELTY OF THIS STUDY WAS TO INVESTIGATE THE CHANGES IN CARDIORESPIRATORY AND METABOLIC INTENSITY BROUGHT ABOUT BY THE PRACTICE OF PRANAYAMAS (BREATHING EXERCISES OF YOGA) AND MEDITATION DURING THE SAME HATHA-YOGA SESSION. THE TECHNIQUE APPLIED WAS THE ONE ADVOCATED BY THE HATHA-YOGA SYSTEM. NINE YOGA INSTRUCTORS-FIVE FEMALES AND FOUR MALES, MEAN AGE OF 44+/-11, 6, WERE SUBJECTED TO ANALYSIS OF THE GASES EXPIRED DURING THREE DISTINCT PERIODS OF 30 MIN: REST, RESPIRATORY EXERCISES AND MEDITATIVE PRACTICE. A METABOLIC OPEN CIRCUIT COMPUTERIZED SYSTEM WAS APPLIED (VO2000, MEDGRAPHICS-USA). THE OXYGEN UPTAKE (VO(2)) AND THE CARBON DIOXIDE OUTPUT (VCO(2)) WERE STATISTICALLY DIFFERENT (P <OR= 0.05) DURING MEDITATION AND PRANAYAMA PRACTICES WHEN COMPARED WITH REST. THE HEART RATE ALSO SUFFERED RELEVANT REDUCTIONS WHEN RESULTS AT REST WERE COMPARED WITH THOSE DURING MEDITATION. A SMALLER PROPORTION OF LIPIDS WAS METABOLIZED DURING MEDITATION PRACTICE COMPARED WITH REST. THE RESULTS SUGGEST THAT THE MEDITATION USED IN THIS STUDY REDUCES THE METABOLIC RATE WHEREAS THE SPECIFIC PRANAYAMA TECHNIQUE IN THIS STUDY INCREASES IT WHEN COMPARED WITH THE REST STATE.	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
14  463  38 CHANGES IN SHAPE AND SIZE DISCRIMINATION AND STATE ANXIETY AFTER ALTERNATE-NOSTRIL YOGA BREATHING AND BREATH AWARENESS IN ONE SESSION EACH. 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
15 1355  29 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
16 1351  33 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
17 1261  34 FINGER DEXTERITY AND VISUAL DISCRIMINATION FOLLOWING TWO YOGA BREATHING PRACTICES. BACKGROUND: PRACTICING YOGA HAS BEEN SHOWN TO IMPROVE MOTOR FUNCTIONS AND ATTENTION. THOUGH ATTENTION IS REQUIRED FOR FINE MOTOR AND DISCRIMINATION TASKS, THE EFFECT OF YOGA BREATHING TECHNIQUES ON FINE MOTOR SKILLS AND VISUAL DISCRIMINATION HAS NOT BEEN ASSESSED. AIM: TO STUDY THE EFFECT OF YOGA BREATHING TECHNIQUES ON FINGER DEXTERITY AND VISUAL DISCRIMINATION. MATERIALS AND METHODS: THE PRESENT STUDY CONSISTED OF ONE HUNDRED AND FORTY SUBJECTS WHO HAD ENROLLED FOR STRESS MANAGEMENT. THEY WERE RANDOMLY DIVIDED INTO TWO GROUPS, ONE GROUP PRACTICED HIGH FREQUENCY YOGA BREATHING WHILE THE OTHER GROUP PRACTICED BREATH AWARENESS. HIGH FREQUENCY YOGA BREATHING (KAPALABHATI, BREATH RATE 1.0 HZ) AND BREATH AWARENESS ARE TWO YOGA PRACTICES WHICH IMPROVE ATTENTION. THE IMMEDIATE EFFECT OF HIGH FREQUENCY YOGA BREATHING AND BREATH AWARENESS (I) WERE ASSESSED ON THE PERFORMANCE ON THE O'CONNOR FINGER DEXTERITY TASK AND (II) (IN) A SHAPE AND SIZE DISCRIMINATION TASK. RESULTS: THERE WAS A SIGNIFICANT IMPROVEMENT IN THE FINGER DEXTERITY TASK BY 19% AFTER KAPALABHATI AND 9% AFTER BREATH AWARENESS (P<0.001 IN BOTH CASES, REPEATED MEASURES ANOVA AND POST-HOC ANALYSES). THERE WAS A SIGNIFICANT REDUCTION (P<0.001) IN ERROR (41% AFTER KAPALABHATI AND 21% AFTER BREATH AWARENESS) AS WELL AS TIME TAKEN TO COMPLETE THE SHAPE AND SIZE DISCRIMINATION TEST (15% AFTER KAPALABHATI AND 15% AFTER BREATH AWARENESS; P<0.001) WAS ALSO OBSERVED. CONCLUSION: BOTH KAPALABAHATI AND BREATH AWARENESS CAN IMPROVE FINE MOTOR SKILLS AND VISUAL DISCRIMINATION, WITH A GREATER MAGNITUDE OF CHANGE AFTER KAPALABHATI.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
18  678  28 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
19   98  38 A NONRANDOMIZED NON-NAIVE COMPARATIVE STUDY OF THE EFFECTS OF KAPALABHATI AND BREATH AWARENESS ON EVENT-RELATED POTENTIALS IN TRAINED YOGA PRACTITIONERS. OBJECTIVES: THE STUDY WAS CONDUCTED TO COMPARE THE P300 EVENT-RELATED POTENTIALS RECORDED BEFORE AND AFTER (1) HIGH-FREQUENCY YOGA BREATHING (HFYB) AND (2) BREATH AWARENESS. DESIGN: THE P300 WAS RECORDED IN PARTICIPANTS OF TWO GROUPS BEFORE AND AFTER THE INTERVENTION SESSION (1 MINUTE IN DURATION). SETTINGS AND LOCATION: ALL PARTICIPANTS WERE RECEIVING YOGA TRAINING IN A RESIDENTIAL YOGA CENTER, SWAMI VIVEKANADA YOGA RESEARCH FOUNDATION IN BANGALORE, INDIA. SUBJECTS: THIRTY (30) MALE PARTICIPANTS FORMED TWO GROUPS (N = 15 EACH) WITH COMPARABLE AGES (WITHIN AN AGE RANGE OF 20-35 YEARS) AND COMPARABLE EXPERIENCE OF THE TWO TECHNIQUES, THE MINIMUM EXPERIENCE BEING 3 MONTHS. INTERVENTIONS: THE TWO GROUPS WERE EACH GIVEN A SEPARATE INTERVENTION. ONE GROUP PRACTICED A HFYB AT A FREQUENCY OF APPROXIMATELY 2.0 HZ, CALLED KAPALABHATI. THE OTHER GROUP PRACTICED BREATH AWARENESS DURING WHICH PARTICIPANTS WERE AWARE OF THEIR BREATH WHILE SEATED, RELAXED. OUTCOME MEASURES: THE P300 EVENT-RELATED POTENTIAL, WHICH IS GENERATED WHEN ATTENDING TO AND DISCRIMINATING BETWEEN AUDITORY STIMULI, WAS RECORDED BEFORE AND AFTER BOTH TECHNIQUES. RESULTS: THE P300 PEAK LATENCY DECREASED AFTER HFYB AND THE P300 PEAK AMPLITUDE INCREASED AFTER BREATH AWARENESS. CONCLUSIONS: BOTH PRACTICES (HFYB AND BREATH AWARENESS), THOUGH VERY DIFFERENT, INFLUENCED THE P300. HFYB REDUCED THE PEAK LATENCY, SUGGESTING A DECREASE IN TIME NEEDED FOR THIS TASK, WHICH REQUIRES SELECTIVE ATTENTION. BREATH AWARENESS INCREASED THE P300 PEAK AMPLITUDE, SUGGESTING AN INCREASE IN THE NEURAL RESOURCES AVAILABLE FOR THE TASK.	2009	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
20  341  38 ARTERIAL BLOOD PRESSURE AND CARDIOVASCULAR RESPONSES TO YOGA PRACTICE. CONTEXT: YOGA IS QUALITATIVELY DIFFERENT FROM ANY OTHER MODE OF PHYSICAL ACTIVITY IN THAT IT CONSISTS OF A UNIQUE COMBINATION OF ISOMETRIC MUSCULAR CONTRACTIONS, STRETCHING EXERCISES, RELAXATION TECHNIQUES, AND BREATHING EXERCISES. IN PARTICULAR, YOGA POSTURES CONSIST OF SYSTEMIC ISOMETRIC CONTRACTIONS THAT ARE KNOWN TO ELICIT MARKED INCREASES IN MEAN BLOOD PRESSURE THAT ARE NOT OBSERVED DURING DYNAMIC EXERCISE. STRETCHING CAN ALSO INDUCE INCREASES IN BLOOD PRESSURE AND SYMPATHETIC NERVE ACTIVITY IN THE MUSCLES. CURRENTLY, NOT MUCH IS KNOWN ABOUT CHANGES IN BLOOD PRESSURE AND OTHER CARDIOVASCULAR RESPONSES TO YOGA PRACTICE. OBJECTIVE: THE STUDY INTENDED TO DETERMINE THE ACUTE EFFECTS OF ONE SESSION OF HATHA YOGA PRACTICE ON BLOOD PRESSURE AND OTHER CARDIOVASCULAR RESPONSES. TO GAIN INSIGHT INTO THE LONG-TERM EFFECTS OF YOGA PRACTICE, BOTH NOVICE (N = 19) AND ADVANCED (N = 18) YOGA PRACTITIONERS WERE STUDIED. DESIGN: THE TWO GROUPS WERE MATCHED FOR AGE, GENDER, BMI, AND BLOOD PRESSURE. SETTING: THE SETTING WAS A RESEARCH LABORATORY AT A UNIVERSITY. PARTICIPANTS: THIRTY-SIX APPARENTLY HEALTHY, NONOBESE, SEDENTARY, OR RECREATIONALLY ACTIVE INDIVIDUALS FROM THE COMMUNITY PARTICIPATED IN THE STUDY. INTERVENTION THE INTERVENTION COMPRISED ONE SESSION OF YOGA PRACTICE, IN WHICH PARTICIPANTS FOLLOWED A CUSTOM MADE INSTRUCTIONAL VIDEO PROVIDING A YOGA ROUTINE THAT CONSISTED OF A SERIES OF 23 HATHA-BASED YOGA POSTURES. OUTCOME MEASURES: PRIOR TO ARRIVING AT THE LABORATORY, EACH PARTICIPANT COMPLETED A RESEARCH HEALTH QUESTIONNAIRE, A TRAINING-STATUS QUESTIONNAIRE, AND A YOGA-EXPERIENCE QUESTIONNAIRE. PRIOR TO THE YOGA PRACTICE, EACH PARTICIPANT'S HEIGHT, BODY FAT PERCENTAGE, TRUNK OR LUMBAR FLEXIBILITY, AND ARTERIAL STIFFNESS AS ASSESSED BY CAROTID FEMORAL PULSE WAVE VELOCITY (CFPWV) WERE MEASURED. FOR EACH POSTURE DURING THE YOGA PRACTICE, THE STUDY CONTINUOUSLY MEASURED SYSTOLIC, MEAN, AND DIASTOLIC BLOOD PRESSURES, HEART RATE, STROKE VOLUME, AND CARDIAC OUTPUT. RESULTS: SYSTOLIC, MEAN, AND DIASTOLIC BLOOD PRESSURES INCREASED SIGNIFICANTLY DURING THE YOGA PRACTICE. THE MAGNITUDE OF THESE INCREASES IN BLOOD PRESSURE WAS GREATEST WITH STANDING POSTURES. HEART RATE AND CARDIAC OUTPUT INCREASED SIGNIFICANTLY DURING YOGA PRACTICE, ESPECIALLY WITH STANDING POSTURES. OVERALL, NO DIFFERENCES EXISTED IN CARDIOVASCULAR RESPONSES BETWEEN THE NOVICE AND ADVANCED PRACTITIONERS THROUGHOUT THE YOGA TESTING SESSION; CFPWV VELOCITY WAS SIGNIFICANTLY AND INVERSELY ASSOCIATED WITH LUMBAR FLEXION BUT NOT WITH SIT-AND-REACH TEST SCORES. CONCLUSIONS: THE RESEARCH TEAM CONCLUDED THAT A VARIETY OF HATHA YOGA POSTURES, ESPECIALLY STANDING POSTURES, EVOKED SIGNIFICANT INCREASES IN BLOOD PRESSURE. THE ELEVATION IN BLOOD PRESSURE DUE TO YOGA PRACTICE WAS ASSOCIATED WITH INCREASES IN CARDIAC OUTPUT AND HEART RATE, WHICH ARE RESPONSES SIMILAR TO THOSE OBSERVED IN ISOMETRIC EXERCISE. THE LACK OF OBVIOUS DIFFERENCES IN BLOOD PRESSURE AND OTHER CARDIOVASCULAR RESPONSES BETWEEN NOVICE AND ADVANCED YOGA PRACTITIONERS SUGGESTS THAT LONG-TERM YOGA PRACTICE DOES NOT ATTENUATE ACUTE YOGA RESPONSES.	2013
