1 1706 98 PATTERN OF BREATHING AND VENTILATORY RESPONSE TO CO2 IN SUBJECTS PRACTICING HATHA-YOGA. WE STUDIED EIGHT BELGIAN SUBJECTS WELL ADVANCED IN THE PRACTICE OF HATHA-YOGA AND COMPARED THEM WITH EIGHT SEX-, AGE-, AND HEIGHT-MATCHED CONTROL SUBJECTS. PRACTICE OF YOGA (RANGE 4-12 YR) INVOLVES CONTROL OF POSTURE AND MANIPULATION OF BREATHING, INCLUDING SLOW NEAR-VITAL CAPACITY MANEUVERS ACCOMPANIED BY APNEA AT END INSPIRATION AND END EXPIRATION. AVERAGE VALUES FOR THE YOGA AND THE CONTROL GROUP (IN PARENTHESES) ARE AS FOLLOWS: VENTILATION (VE) 5.53 1 X MIN-1 (7.07); TIDAL VOLUME (VT), 1.03 LITERS (0.56); RATE OF BREATHING, 5.5 MIN-1 (13.4); END-TIDAL PCO2, 39.0 TORR (35.3). ALL DIFFERENCES ARE SIGNIFICANT (P LESS THAN 0.05). VENTILATORY RESPONSE TO CO2 (REBREATHING TECHNIQUE) WAS SIGNIFICANTLY LOWER IN THE YOGA GROUP (P LESS THAN 0.01). THE REGRESSION RELATING VE TO VT DURING REBREATHING OF CO2 WAS VE = 8.1 (VT - 0.23) FOR THE YOGA GROUP AND VE = 15.8 (VT - 0.16) FOR THE CONTROL GROUP (P LESS THAN 0.005). WE ATTRIBUTE THESE CHANGES TO CHRONIC MANIPULATION OF RESPIRATION.	1981	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
2  637 26 DO 12-WEEK YOGA PROGRAM INFLUENCE RESPIRATORY FUNCTION OF ELDERLY WOMEN? AGING PRODUCES SEVERAL RESPIRATORY LIMITATIONS AND REDUCES TOLERANCE TO PHYSICAL EFFORTS, SOMETIMES LEADING TO PULMONARY DISEASES IN THE ELDERLY. THE LITERATURE DRAWS ATTENTION TO THE POSSIBLE BENEFITS OF YOGA PRACTICE AMONG THE ELDERLY, PRESENTING EVIDENCE FOR SIGNIFICANT IMPROVEMENTS IN QUALITY OF LIFE. IT WAS HYPOTHESIZED THAT YOGA PRACTICE CAN IMPROVE RESPIRATORY FUNCTION IN THE ELDERLY. THE EFFECTS OF A YOGA PROGRAM ON PULMONARY VOLUMES AND RESPIRATORY MUSCLE STRENGTH WERE VERIFIED IN 36 ELDERLY WOMEN DIVIDED INTO A YOGA GROUP [YG] (63.1 +/- 13.3 YEARS OF AGE) AND A CONTROL GROUP (61.0 +/- 6.9 YEARS OF AGE). MAXIMAL INSPIRATORY AND EXPIRATORY PRESSURE (MIP AND MEP) WERE ASSESSED BY A MANOVACUOMETER AND TIDAL VOLUME (VT), VITAL CAPACITY (VC) AND MINUTE VENTILATION (VE) WERE MEASURED BY A VENTILOMETER. THE PROGRAM COMPRISED 65 MIN SESSIONS, 3 TIMES/WEEK DURING 12 WEEKS. THE HEART RATE AND RESPIRATORY RATE DECREASED SIGNIFICANTLY IN THE YG (76-39 +/- 8-03 VS. 74-61+/-10.26 BPM AND 18.61 +/- 3.15 VS. 16.72 +/- 3.12 RESP/MIN, RESPECTIVELY). IN THE YG, VT AND VE INCREASED SIGNIFICANTLY (0.55 +/- 0.22 VS. 0.64 +/- 0.2 ML AND 9.19 +/- 2.39 VS. 10.05 +/- 2.11 ML, RESPECTIVELY), AS WELL AS VC (1.48 +/- 0.45 VS. 2.03 +/- 0.72 ML). IMPROVEMENTS WERE ALSO FOUND IN MIP AND MEP IN THE YG (62.17 +/- 14.77 VS. 73.06 +/- 20.16 CMH2O AND 80.56 +/- 23.94 VS. 86.39 +/- 20.16 CMH2O, RESPECTIVELY). IT WAS CONCLUDED THAT A 12-WEEK YOGA PROGRAM SIGNIFICANTLY IMPROVES PULMONARY FUNCTION OF AGED WOMEN.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
3  741 27 EFFECT OF REGULAR YOGA PRACTICE ON RESPIRATORY REGULATION AND EXERCISE PERFORMANCE. YOGA ALTERS SPONTANEOUS RESPIRATORY REGULATION AND REDUCES HYPOXIC AND HYPERCAPNIC VENTILATORY RESPONSES. SINCE A LOWER VENTILATORY RESPONSE IS ASSOCIATED WITH AN IMPROVED ENDURANCE CAPACITY DURING WHOLE-BODY EXERCISE, WE TESTED WHETHER YOGIC SUBJECTS (YOGA) SHOW AN INCREASED ENDURANCE CAPACITY COMPARED TO MATCHED NON-YOGIC INDIVIDUALS (CON) WITH SIMILAR PHYSICAL ACTIVITY LEVELS. RESTING VENTILATION, THE VENTILATORY RESPONSE TO HYPERCAPNIA, PASSIVE LEG MOVEMENT AND EXERCISE, AS WELL AS ENDURANCE PERFORMANCE WERE ASSESSED. YOGA (N = 9), COMPARED TO CONTROL (N = 6), HAD A HIGHER TIDAL VOLUME AT REST (0.7+/-0.2 VS. 0.5+/-0.1 L, P = 0.034) AND A REDUCED VENTILATORY RESPONSE TO HYPERCAPNIA (33+/-15 VS. 47+/-15 L.MIN(-1), P = 0.048). A YOGA SUBGROUP (N = 6) WITH MAXIMAL PERFORMANCE SIMILAR TO CONTROL SHOWED A BLUNTED VENTILATORY RESPONSE TO PASSIVE CYCLING (11+/-2 VS. 14+/-2 L.MIN(-1), P = 0.039) AND A TENDENCY TOWARDS LOWER EXERCISE VENTILATION (33+/-2 VS. 36+/-3 L.MIN(-1), P = 0.094) WHILE CYCLING ENDURANCE (YOGA: 17.3+/-3.3; CON: 19.6+/-8.5 MIN, P = 0.276) DID NOT DIFFER. THUS, YOGA PRACTICE WAS NOT ASSOCIATED WITH IMPROVED EXERCISE CAPACITY NOR WITH SIGNIFICANT CHANGES IN EXERCISE VENTILATION DESPITE A SIGNIFICANTLY DIFFERENT RESPIRATORY REGULATION AT REST AND IN RESPONSE TO HYPERCAPNIA AND PASSIVE LEG MOVEMENT.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
4 2005 20 STUDY OF PULMONARY AND AUTONOMIC FUNCTIONS OF ASTHMA PATIENTS AFTER YOGA TRAINING. "THE CONCEPT OF YOGA IS HELPFUL FOR THE TREATMENT OF BRONCHIAL ASTHMA", HAS CREATED A GREAT INTEREST IN THE MEDICAL RESEARCH FIELD. IN ORDER TO INVESTIGATE WHETHER AUTONOMIC FUNCTIONS AND PULMONARY FUNCTIONS ARE IMPROVED IN ASTHMA PATIENTS AFTER SHORT TERM YOGA TRAINING, A STUDY WAS CONDUCTED WITH NINE DIAGNOSED BRONCHIAL ASTHMA PATIENTS. YOGA TRAINING WAS GIVEN FOR SEVEN DAYS IN A CAMP IN ADHYATMA SADHNA KENDRA, NEW DELHI. THE AUTONOMIC FUNCTION TESTS TO MEASURE THE PARASYMPATHETIC REACTIVITY (DEEP BREATHING TEST, VALSALVA MANOUEVER), SYMPATHETIC REACTIVITY (HAND GRIP TEST, COLD PRESSURE TEST), AND PULMONARY FUNCTION TESTS FVC, FEV1, PEFR, PIF, BHT AND CE WERE RECORDED BEFORE AND AFTER YOGA TRAINING. THE RESTING HEART RATE AFTER YOGA TRAINING (P < 0.05) WAS SIGNIFICANTLY DECREASED (89.55 +/- 18.46/MIN TO 76.22 +/- 16.44/MIN). THE SYMPATHETIC REACTIVITY WAS REDUCED FOLLOWING YOGA TRAINING AS INDICATED BY SIGNIFICANT (P < 0.01) REDUCTION IN DBP AFTER HGT. THERE WAS NO CHANGE IN PARASYMPATHETIC REACTIVITY. THE FVC, FEV1, PEFR DID NOT SHOW ANY SIGNIFICANT CHANGE. THE PIF (P < 0.01), BHT (P < 0.01) AND CE (P < 0.01) SHOWED SIGNIFICANT IMPROVEMENT. THE RESULTS CLOSELY INDICATED THE REDUCTION IN SYMPATHETIC REACTIVITY AND IMPROVEMENT IN THE PULMONARY VENTILATION BY WAY OF RELAXATION OF VOLUNTARY INSPIRATORY AND EXPIRATORY MUSCLES. THE "COMPREHENSIVE YOGIC LIFE STYLE CHANGE PROGRAMME FOR PATIENTS OF BRONCHIAL ASTHMA" HAVE SHOWN SIGNIFICANT BENEFIT EVEN WITHIN A SHORT PERIOD.	1996	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
5  887 16 EFFECT OF YOGA TYPE BREATHING ON HEART RATE AND CARDIAC AXIS OF NORMAL SUBJECTS. EFFECT OF INSPIRATORY AND EXPIRATORY PHASES OF NORMAL QUIET BREATHING, DEEP BREATHING AND SAVITRI PRANAYAM TYPE BREATHING ON HEART RATE AND MEAN VENTRICULAR QRS AXIS WAS INVESTIGATED IN YOUNG, HEALTHY UNTRAINED SUBJECTS. PRANAYAM TYPE BREATHING PRODUCED SIGNIFICANT CARDIOACCELERATION AND INCREASE IN QRS AXIS DURING THE INSPIRATORY PHASE AS COMPARED TO EUPNEA. ON THE OTHER HAND, EXPIRATORY EFFORT DURING PRANAYAM TYPE BREATHING DID NOT PRODUCE ANY SIGNIFICANT CHANGE IN HEART RATE OR QRS AXIS. THE CHANGES IN HEART RATE AND QRS AXIS DURING THE INSPIRATORY AND EXPIRATORY PHASES OF PRANAYAM TYPE BREATHING WERE SIMILAR TO THE CHANGES OBSERVED DURING THE CORRESPONDING PHASES OF DEEP BREATHING.	1986	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
6 1112 28 EFFICACY AND TOLERABILITY OF YOGA BREATHING IN PATIENTS WITH CHRONIC OBSTRUCTIVE PULMONARY DISEASE: A PILOT STUDY. PURPOSE: YOGA-DERIVED BREATHING HAS BEEN REPORTED TO IMPROVE GAS EXCHANGE IN PATIENTS WITH CHRONIC HEART FAILURE AND IN PARTICIPANTS EXPOSED TO HIGH-ALTITUDE HYPOXIA. WE INVESTIGATED THE TOLERABILITY AND EFFECT OF YOGA BREATHING ON VENTILATORY PATTERN AND OXYGENATION IN PATIENTS WITH CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD). METHODS: PATIENTS WITH COPD (N = 11, 3 WOMEN) WITHOUT PREVIOUS YOGA PRACTICE AND TAKING ONLY SHORT-ACTING BETA2-ADRENERGIC BLOCKING DRUGS WERE ENROLLED. VENTILATORY PATTERN AND OXYGEN SATURATION WERE MONITORED BY MEANS OF INDUCTIVE PLETHYSMOGRAPHY DURING 30-MINUTE SPONTANEOUS BREATHING AT REST (SB) AND DURING A 30-MINUTE YOGA LESSON (Y). DURING THE YOGA LESSON, THE PATIENTS WERE REQUESTED TO MOBILIZE IN SEQUENCE THE DIAPHRAGM, LOWER CHEST, AND UPPER CHEST ADOPTING A SLOWER AND DEEPER BREATHING. WE EVALUATED OXYGEN SATURATION (SAO2%), TIDAL VOLUME (VT), MINUTE VENTILATION (E), RESPIRATORY RATE (I>F), INSPIRATORY TIME, TOTAL BREATH TIME, FRACTIONAL INSPIRATORY TIME, AN INDEX OF THORACOABDOMINAL COORDINATION, AND AN INDEX OF RAPID SHALLOW BREATHING. CHANGES IN DYSPNEA DURING THE YOGA LESSON WERE ASSESSED WITH THE BORG SCALE. RESULTS: DURING THE YOGA LESSON, DATA SHOWED THE ADOPTION OF A DEEPER AND SLOWER BREATHING PATTERN (VTSB L 0.54[0.04], VTY L 0.74[0.08], P = .01; I>FSB 20.8[1.3], I>FY 13.8[0.2], P = .001) AND A SIGNIFICANT IMPROVEMENT IN SAO2% WITH NO CHANGE IN E (SAO2%SB 91.5%[1.13], SAO2%Y 93.5%[0.99], P = .02; ESB L/MIN 11.2[1.1], EY L/MIN 10.2[0.9]). ALL THE PARTICIPANTS REPORTED TO BE COMFORTABLE DURING THE YOGA LESSON, WITH NO INCREASE IN DYSPNEA INDEX. CONCLUSION: WE CONCLUDE THAT SHORT-TERM TRAINING IN YOGA IS WELL TOLERATED AND INDUCES FAVORABLE RESPIRATORY CHANGES IN PATIENTS WITH COPD.	2009	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
7 2363 25 VOLUNTARILY INDUCED VOMITING - A YOGA TECHNIQUE TO ENHANCE PULMONARY FUNCTIONS IN HEALTHY HUMANS. VOMITING IS A COMPLEX AUTONOMIC REFLEX ORCHESTRATED BY SEVERAL NEUROLOGICAL CENTRES IN THE BRAIN. VAGUS, THE CRANIAL NERVE PLAYS A KEY ROLE IN REGULATION OF VOMITING. KUNJAL KRIYA (VOLUNTARILY INDUCED VOMITING), IS A YOGIC CLEANSING TECHNIQUE WHICH INVOLVES VOLUNTARILY INDUCING VOMITING AFTER DRINKING SALINE WATER (5%) ON EMPTY STOMACH. THIS STUDY WAS DESIGNED WITH AN OBJECTIVE TO UNDERSTAND THE EFFECT OF VOLUNTARY INDUCED VOMITING (VIV) ON PULMONARY FUNCTIONS IN EXPERIENCED PRACTITIONERS AND NOVICES AND DERIVE ITS POSSIBLE THERAPEUTIC APPLICATIONS. EIGHTEEN HEALTHY INDIVIDUALS VOLUNTEERED FOR THE STUDY OF WHICH NINE HAD PRIOR EXPERIENCE OF VIV WHILE NINE DID NOT. PULMONARY FUNCTION TESTS WERE PERFORMED BEFORE AND AFTER 10 MIN OF REST FOLLOWING VIV. ANALYSIS OF COVARIANCE WAS PERFORMED ADJUSTED FOR GENDER AND BASELINE VALUES. NO SIGNIFICANT CHANGES WERE OBSERVED ACROSS GENDERS. THE RESULTS OF THE PRESENT STUDY SUGGEST A SIGNIFICANT INCREASE IN SLOW VITAL CAPACITY [F(1,13) = 5.699; P = 0.03] AND FORCED INSPIRATORY VOLUME IN 1ST SECOND [P = 0.02] AND REDUCTION IN EXPIRATORY RESERVE VOLUME [F(1,13) = 5.029; P = 0.04] AND RESPIRATORY RATE [F(1,13) = 3.244, P = 0.09]. THESE CHANGES SUGGEST THE POSSIBLE ROLE OF VIV IN ENHANCING THE ENDURANCE OF THE RESPIRATORY MUSCLES, DECREASED AIRWAY RESISTANCE, BETTER EMPTYING OF LUNGS AND VAGAL PREDOMINANCE RESPECTIVELY. WE CONCLUDE THAT VIV WHEN PRACTICED REGULARLY ENHANCES THE ENDURANCE OF THE RESPIRATORY MUSCLES AND DECREASES AIRWAY RESISTANCE. THESE FINDINGS ALSO INDICATE NEED FOR SCIENTIFIC UNDERSTANDING OF VIV IN THE MANAGEMENT OF MOTION SICKNESS AND RESTRICTIVE PULMONARY DISORDERS LIKE BRONCHITIS AND BRONCHIAL ASTHMA.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
8 2905 30 [LONG-TERM EFFECTS OF BREATHING EXERCISES AND YOGA IN PATIENTS WITH BRONCHIAL ASTHMA]. TO COMPARE THE EFFECTS OF BREATHING EXERCISES (BE) OR YOGA (Y) ON THE COURSE OF BRONCHIAL ASTHMA WE STUDIED 36 SUBJECTS WITH A MILD DISEASE. THE PATIENTS WERE RANDOMLY DIVIDED INTO 3 GROUPS. 2 OF THEM PARTICIPATED IN A 3 WEEKS TRAINING PROGRAM OF BE OR Y WHILE THE THIRD GROUP RESTED WITHOUT ANY ADDITIONAL TREATMENT (CONTROL GROUP, C). AT THE END OF THE TRAINING PERIOD THE PATIENTS WERE ASKED TO PRACTISE BE OR Y ON THEIR OWN. DRUG THERAPY AND LUNG FUNCTION PARAMETERS BEFORE AND AFTER A BETA 2-AGONIST METERED DOSE INHALER (ALBUTEROL, ALB) WERE RECORDED PRIOR TO THE TRAINING PROGRAM AND IN 4 WEEKS INTERVALS FOR 4 MONTHS THEREAFTER. THE RESPONSE TO THE BETA 2-AGONIST WAS DOCUMENTED CONTINUOUSLY IN 28 PATIENTS. THE MENTAL STATE OF THE PATIENTS WAS ELUCIDATED BY QUESTIONNAIRES.--PRIOR TO THE STUDY A SIGNIFICANT EFFECT OF INHALED ALB ON THE FEV1 WAS SHOWN WITHOUT ANY SIGNIFICANT BETWEEN GROUP DIFFERENCES. BOTH, BE AND Y, CAUSED A SIGNIFICANT AMELIORATION OF THE MENTAL STATE BUT ONLY THE BE INDUCED A SIGNIFICANT IMPROVEMENT OF LUNG FUNCTION PARAMETERS COMPARED TO THE INDIVIDUAL BASELINE VALUES. THE FEV1 INCREASED SIGNIFICANTLY BY 356.3 +/- 146.2 ML (P < 0.05) AND THE VC BY 225.0 +/- 65.5 ML (P < 0.01). THESE LONG-TERM CHANGES WERE NOT SIGNIFICANTLY DIFFERENT FROM THE ACTUAL RESPONSE TO ALB. BE DECREASED THE RV SIGNIFICANTLY BY 306.3 +/- 111.6 ML (P < 0.05), AN EFFECT SIGNIFICANTLY HIGHER COMPARED TO THE BETA 2-AGONIST (P < 0.01). BE IN COMBINATION WITH ALB CAUSED AN ADDITIVE EFFECT.(ABSTRACT TRUNCATED AT 250 WORDS)	1994	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
9 2257 17 THE PHYSIOLOGICAL CORRELATES OF KUNDALINI YOGA MEDITATION: A STUDY OF A YOGA MASTER. THIS STUDY EXPLORES THE PHYSIOLOGICAL CORRELATES OF A HIGHLY PRACTICED KUNDALINI YOGA MEDITATOR. THORACIC AND ABDOMINAL BREATHING PATTERNS, HEART RATE (HR), OCCIPITAL PARIETAL ELECTROENCEPHALOGRAPH (EEG), SKIN CONDUCTANCE LEVEL (SCL), AND BLOOD VOLUME PULSE (BVP) WERE MONITORED DURING PREBASELINE, MEDITATION, AND POSTBASELINE PERIODS. VISUAL ANALYSES OF THE DATA SHOWED A DECREASE IN RESPIRATION RATE DURING THE MEDITATION FROM A MEAN OF 11 BREATHS/MIN FOR THE PRE- AND 13 BREATHS/MIN FOR THE POSTBASELINE TO A MEAN OF 5 BREATHS/MIN DURING THE MEDITATION, WITH A PREDOMINANCE OF ABDOMINAL/DIAPHRAGMATIC BREATHING. THERE WAS ALSO MORE ALPHA EEG ACTIVITY DURING THE MEDITATION (M = 1.71 MICROV) COMPARED TO THE PRE- (M = .47 MICROV) AND POSTBASELINE (M = .78 MICROV) PERIODS, AND AN INCREASE IN THETA EEG ACTIVITY IMMEDIATELY FOLLOWING THE MEDITATION (M = .62 MICROV) COMPARED TO THE PRE-BASELINE AND MEDITATIVE PERIODS (EACH WITH M = .26 MICROV). THESE FINDINGS SUGGEST THAT A SHIFT IN BREATHING PATTERNS MAY CONTRIBUTE TO THE DEVELOPMENT OF ALPHA EEG, AND THOSE PATTERNS NEED TO BE INVESTIGATED FURTHER.	2001

WE TESTED WHETHER CHEMOREFLEX SENSITIVITY COULD BE AFFECTED BY THE PRACTICE OF YOGA, AND WHETHER THIS IS SPECIFICALLY BECAUSE OF A SLOW BREATHING RATE OBTAINED DURING YOGA OR AS A GENERAL CONSEQUENCE OF YOGA. WE FOUND THAT SLOW BREATHING RATE PER SE SUBSTANTIALLY REDUCED CHEMOREFLEX SENSITIVITY, BUT LONG-TERM YOGA PRACTICE WAS RESPONSIBLE FOR A GENERALISED REDUCTION IN CHEMOREFLEX.	2000	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
11  417 22 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
12  416 20 BODY TEMPERATURE AND ENERGY EXPENDITURE DURING AND AFTER YOGA BREATHING PRACTICES TRADITIONALLY DESCRIBED AS COOLING. BACKGROUND IN TRADITIONAL YOGA TEXTS, SHEETALI AND SITKARI PRANAYAMAS ARE DESCRIBED AS COOLING. THE PRESENT STUDY WAS AIMED AT RECORDING THE SURFACE BODY TEMPERATURE, OXYGEN CONSUMED, AND CARBON DIOXIDE ELIMINATED BEFORE, DURING, AND AFTER PERFORMANCE OF SHEETALI AND SITKARI PRANAYAMAS. MATERIAL AND METHODS SEVENTEEN HEALTHY MALE VOLUNTEERS WITH AGES BETWEEN 19 TO 25 YEARS (AVERAGE AGE 20.7+/-1.8 YEARS) WERE ASSESSED IN 4 SESSIONS, VIZ. SHEETALI PRANAYAMA, SITKARI PRANAYAMA, BREATH AWARENESS AND QUIET LYING, ON 4 SEPARATE DAYS, IN RANDOM SEQUENCE. THE AXILLARY SURFACE BODY TEMPERATURE (TRUSCOPE II, SCHILLER, CHINA) AND METABOLIC VARIABLES (QUARK CPET, COSMED, ITALY) WERE RECORDED IN 3 PERIODS: BEFORE (5 MINUTES), DURING (18 MINUTES), AND AFTER (5 MINUTES), IN EACH OF THE 4 SESSIONS. THE HEAT INDEX WAS CALCULATED IN THE BEFORE AND AFTER PERIODS, BASED ON RECORDINGS OF AMBIENT TEMPERATURE AND HUMIDITY. DATA WERE ANALYZED USING SPSS (VERSION 24.0). RESULTS BODY TEMPERATURE INCREASED SIGNIFICANTLY DURING SHEETALI AND SITKARI (P<0.05, P<0.01; RESPECTIVELY) WHILE IT DECREASED AFTER BREATH AWARENESS AND QUIET LYING DOWN (P<0.01, P<0.001; RESPECTIVELY) WHEN COMPARED WITH RESPECTIVE POST-EXERCISE STATES. OXYGEN CONSUMPTION INCREASED BY 9.0% DURING SHEETALI (P<0.05) AND BY 7.6% DURING SITKARI (P<0.01) WHILE IT DECREASED SIGNIFICANTLY DURING (P<0.05) AND AFTER (P<0.01) QUIET LYING DOWN COMPARED TO RESPECTIVE PRE-EXERCISE STATES. CONCLUSIONS THE RESULTS DO NOT SUPPORT THE DESCRIPTION OF THESE YOGA BREATHING PRACTICES AS COOLING. THESE YOGA BREATHING PRACTICES MAY BE USED TO INDUCE A MILD HYPERMETABOLIC STATE.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
13  736 22 EFFECT OF PRACTICING YOGA ON CERVICAL VESTIBULAR EVOKED MYOGENIC POTENTIAL. THE PRESENT STUDY ATTEMPTED TO DETERMINE THE EFFECT OF PRACTICING YOGA ON FUNCTIONING OF SACCULO-COLLIC PATHWAY USING CERVICAL VESTIBULAR EVOKED MYOGENIC POTENTIAL (CVEMP). CVEMP WAS RECORDED FROM 40 PARTICIPANTS (20 WHO PRACTICE YOGA REGULARLY AND 20 WHO DO NOT PRACTICE YOGA REGULARLY). THE DIFFERENCES IN AMPLITUDE OF P1, N1, P1-N1 COMPLEX, ASYMMETRY RATIO AND LATENCIES OF P1 AND N1 OF CVEMP WERE COMPARED BETWEEN BOTH THE GROUPS. THE RESULTS OF THE STUDY SHOWED THAT THERE WAS A SIGNIFICANT INCREASE (P < 0.05) IN THE AMPLITUDE OF P1, N1 AND P1-N1 COMPLEX AND A SIGNIFICANT REDUCTION IN LATENCY (P < 0.05) FOR EXPERIMENTAL GROUP. THE ASYMMETRY RATIO IN INDIVIDUALS WHO PRACTICE YOGA WAS SIGNIFICANTLY LOWER (MEAN = 6.73) COMPARED TO THE CONTROL GROUP (MEAN = 19.13). MULTIVARIATE REGRESSION ANALYSES SUGGESTED THAT THE NUMBER OF YEARS OF YOGA PRACTICE SIGNIFICANTLY PREDICTED THE AMPLITUDE OF P1-N1 COMPLEX (BETA = 0.70, P < 0.01) AND AMPLITUDE RATIO (BETA = 0.72, P < 0.01). THUS, PRACTICING YOGA IMPROVES POSTURAL CONTROL AND STRENGTHENS THE MUSCLES AND VESTIBULAR SYSTEM LEADING TO ENHANCED CVEMP RESPONSES. THE PLASTIC CHANGES IN THE VESTIBULAR SYSTEM AND INCREASED MUSCULAR STRENGTH BECAUSE OF CONSTANT PRACTICING OF YOGA COULD HAVE LED TO CHANGES IN CVEMP RESPONSES. HOWEVER, FURTHER STUDIES ON A LARGER GROUP OF INDIVIDUALS ARE ESSENTIAL FOR BETTER CLINICAL APPLICABILITY OF THE RESULTS.	2017

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	2014	

15  821 15 EFFECT OF YOGA ON EXERCISE TOLERANCE IN NORMAL HEALTHY VOLUNTEERS. TWELVE NORMAL HEALTHY VOLUNTEERS (6 MALES AND 6 FEMALES) UNDERGOING YOGA TRAINING FOR 90 DAYS WERE STUDIED FOR THE EFFECT OF YOGA ON EXERCISE TOLERANCE. THEIR AGES RANGED FROM 18 TO 28 YEARS. THE VOLUNTEERS WERE TAUGHT ONLY PRANAYAMA FOR THE FIRST 20 DAYS AND LATER ON YOGIC ASANAS WERE ADDED. SUB-MAXIMAL EXERCISE TOLERANCE TEST WAS DONE ON A MOTORIZED TREADMILL BY USING BALKE'S MODIFIED PROTOCOL, INITIALLY, AFTER 20 DAYS (PHASE-I) AND AFTER 90 DAYS OF YOGA TRAINING (PHASE-II). PYRUVATE AND LACTATE IN VENOUS BLOOD AND BLOOD GASES IN CAPILLARY BLOOD WERE ESTIMATED IMMEDIATELY BEFORE AND AFTER THE EXERCISE. MINUTE VENTILATION AND OXYGEN CONSUMPTION WERE ESTIMATED BEFORE AND DURING THE TEST. POST EXERCISE BLOOD LACTATE WAS ELEVATED SIGNIFICANTLY DURING INITIAL AND PHASE-I, BUT NOT IN PHASE-II. THERE WAS SIGNIFICANT REDUCTION OF MINUTE VENTILATION AND OXYGEN CONSUMPTION ONLY IN MALES IN PHASE-I AND II AT THE TIME WHEN THE VOLUNTEERS REACHED THEIR 80% OF THE PREDICTED HEART RATE. FEMALE VOLUNTEERS WERE ABLE TO GO TO HIGHER LOADS OF EXERCISE IN PHASE-I AND II.	1986	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
16  804 10 EFFECT OF YOGA ON AEROBIC AND ANAEROBIC POWER OF MUSCLES. AEROBIC POWER (VO2 MAX) AND ANAEROBIC POWER WERE ESTIMATED IN MEDICAL STUDENTS BEFORE AND AFTER SIX WEEKS OF YOGIC TRAINING. A SIGNIFICANT INCREASE IN AEROBIC POWER AND A SIGNIFICANT DECREASE IN ANAEROBIC POWER WAS OBSERVED. THIS MAY BE DUE TO CONVERSION OF SOME OF THE FAST TWITCH (F.T.) MUSCLE FIBRES INTO SLOW TWITCH FIBRES (S.T.) DURING YOGIC TRAINING.	1991	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
17  295 21 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
18  898 16 EFFECT OF YOGASANAS ON THE VISUAL AND AUDITORY REACTION TIME. VISUAL AND AUDITORY REACTION TIME (VRT, ART) WAS STUDIED IN 83 HEALTHY MALE SUBJECTS OF 30-40 YEARS OF AGE WHO HAD NEVER PRACTICED YOGASANAS BEFORE. THESE SUBJECTS WERE DIVIDED INTO TWO GROUPS VIZ. GROUP A WHOSE VRT AND ART WAS DETERMINED AFTER 1 HR. YOGASANAS AND GROUP B WHOSE ART AND VRT WAS DETERMINED AFTER 6 WEEKS YOGASANAS TRAINING PROGRAMME. VRT AND ART SHOWED A SIGNIFICANT REDUCTION IN GROUP A (P LESS THAN .05) AND GROUP B (P LESS THAN .001).	1989	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
19 1932 25 ROLE OF YOGA IN MODIFYING ANXIETY LEVEL IN WOMEN. ANXIETY LEADS TO DERANGEMENT IN PHYSICAL AND MENTAL HEALTH. ANXIETY LEVELS ARE MORE IN FULL TIME HOUSEWIVES THAN WORKING WOMEN. THERE IS A NEED FOR SIMPLE, EASY TREATMENT FOR ANXIETY TO ALLEVIATE THE BURDEN ON HEALTH CAUSED BY ANXIETY. YOGA IS AMONG THE TOP TEN COMPLEMENTARY AND ALTERNATIVE MEDICINE THERAPIES. OUR STUDY AIMED TO DETERMINE THE ANXIETY LEVELS IN APPARENTLY HEALTHY FULL TIME HOUSEWIVES AND TO STUDY THE EFFECTS OF YOGA ON ANXIETY LEVELS AMONG THEM. PRESENT STUDY IS A COMPARATIVE INTERVENTIONAL STUDY. STUDY WAS CONDUCTED ON 50 APPARENTLY HEALTHY FULL TIME HOUSEWIVES (20-50 YEARS) WHO ATTENDED ONE MONTH YOGA CAMP. HAMILTON ANXIETY (HAMA) SCALE WAS USED TO EVALUATE ANXIETY LEVELS BEFORE AND AT THE END OF THE YOGA CAMP. STATISTICAL ANALYSIS WAS DONE BY PAIRED T TEST USING SPSS 9.0. THE BASELINE PULSE RATE, SBP, DBP WERE 82.90 +/- 4.25 BPM, 124.84 +/- 11.022 MM HG, 85.20 +/- 10.81 MM HG RESPECTIVELY. AFTER FOUR WEEKS YOGA CAMP THERE WAS STATISTICALLY SIGNIFICANT LOWERING OF PULSE RATE (77.58 +/- 3.86 BPM), SBP (117.92 +/- 6.76 MM HG), DBP (78.68 +/- 6.62 MM HG). BEFORE YOGA TRAINING, PERCENTAGE DISTRIBUTIONS OF SUBJECTS WITH MILD, MODERATE AND SEVERE ANXIETY WERE 6%, 18% AND 76% RESPECTIVELY. AT THE END OF FOUR WEEK YOGA TRAINING, PERCENTAGE DISTRIBUTIONS OF SUBJECTS WITH MILD, MODERATE AND SEVERE ANXIETY WERE 44.23%, 19.23% AND 36.53% RESPECTIVELY. THERE WAS HIGHLY SIGNIFICANT (P = 0.000) DIFFERENCE IN THE MEAN VALUES OF TOTAL SCORE BEFORE (33.71 +/- 4.90) AND AFTER (26.93 +/- 4.53) YOGA. THESE RESULTS INDICATE THAT THERE WAS A REDUCTION IN THE SEVERITY OF ANXIETY FROM SEVERE TO MODERATE AND MILD INDICATING DECREASE IN ANXIETY FOLLOWING YOGA. BASED ON THE RESULTS OF OUR STUDY, WE CONCLUDE THAT REGULAR YOGIC PRACTICES AND ADAPTING AND IMPLEMENTING THE PRINCIPALS AND PHILOSOPHY OF YOGA IN DAY TO DAY LIFE MAY DECREASE THE ANXIETY LEVEL.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
20  447 23 CHANGED PATTERN OF REGIONAL GLUCOSE METABOLISM DURING YOGA MEDITATIVE RELAXATION. USING POSITRON EMISSION TOMOGRAPHY (PET), MEASUREMENTS OF THE REGIONAL CEREBRAL METABOLIC RATE OF GLUCOSE (RCMRGLC) ARE ABLE TO DELINEATE CEREBRAL METABOLIC RESPONSES TO EXTERNAL OR MENTAL STIMULATION. IN ORDER TO EXAMINE POSSIBLE CHANGES OF BRAIN METABOLISM DUE TO YOGA MEDITATION PET SCANS WERE PERFORMED IN 8 MEMBERS OF A YOGA MEDITATION GROUP DURING THE NORMAL CONTROL STATE (C) AND YOGA MEDITATIVE RELAXATION (YMR). WHEREAS THERE WERE INTRAINDIVIDUAL CHANGES OF THE TOTAL CMRGLC, THE ALTERATIONS WERE NOT SIGNIFICANT FOR INTERGROUP COMPARISON; SPECIFIC FOCAL CHANGES OR CHANGES IN THE INTERHEMISPHERIC DIFFERENCES IN METABOLISM WERE ALSO NOT SEEN; HOWEVER THE RATIOS OF FRONTAL VS. OCCIPITAL RCMRGLC WERE SIGNIFICANTLY ELEVATED (P LESS THAN 0.05) DURING YMR. THESE ALTERED RATIOS WERE CAUSED BY A SLIGHT INCREASE OF FRONTAL RCMRGLC AND A MORE PRONOUNCED REDUCTION IN PRIMARY AND SECONDARY VISUAL CENTERS. THESE DATA INDICATE A HOLISTIC BEHAVIOR OF THE BRAIN METABOLISM DURING THE TIME OF ALTERED STATE OF CONSCIOUSNESS DURING YMR.	1990
