1 1676 127 OBJECTIVE AND SUBJECTIVE MEASURES OF EXERCISE INTENSITY DURING THERMO-NEUTRAL AND HOT YOGA. WHILE HOT YOGA HAS GAINED ENORMOUS POPULARITY IN RECENT YEARS, OWING IN PART TO INCREASED ENVIRONMENTAL CHALLENGE ASSOCIATED WITH EXERCISE IN THE HEAT, IT IS NOT CLEAR WHETHER HOT YOGA IS MORE VIGOROUS THAN THERMO-NEUTRAL YOGA. THEREFORE, THE AIM OF THIS STUDY WAS TO DETERMINE OBJECTIVE AND SUBJECTIVE MEASURES OF EXERCISE INTENSITY DURING CONSTANT INTENSITY YOGA IN A HOT AND THERMO-NEUTRAL ENVIRONMENT. USING A RANDOMIZED, CROSSOVER DESIGN, 14 PARTICIPANTS COMPLETED 2 IDENTICAL APPROXIMATELY 20-MIN YOGA SESSIONS IN A HOT (35.3 +/- 0.8 DEGREES C; HUMIDITY: 20.5% +/- 1.4%) AND THERMO-NEUTRAL (22.1 +/- 0.2 DEGREES C; HUMIDITY: 27.8% +/- 1.6%) ENVIRONMENT. OXYGEN CONSUMPTION AND HEART RATE (HR) WERE RECORDED AS OBJECTIVE MEASURES (PERCENTAGE OF MAXIMAL OXYGEN CONSUMPTION AND PERCENTAGE OF MAXIMAL HR (%HRMAX)) AND RATING OF PERCEIVED EXERTION (RPE) WAS RECORDED AS A SUBJECTIVE MEASURE OF EXERCISE INTENSITY. THERE WAS NO DIFFERENCE IN EXERCISE INTENSITY BASED ON PERCENTAGE OF MAXIMAL OXYGEN CONSUMPTION DURING HOT VERSUS THERMO-NEUTRAL YOGA (30.9% +/- 2.3% VS. 30.5% +/- 1.8%, P = 0.68). HOWEVER, EXERCISE INTENSITY WAS SIGNIFICANTLY HIGHER DURING HOT VERSUS THERMO-NEUTRAL YOGA BASED ON %HRMAX (67.0% +/- 2.3% VS. 60.8% +/- 1.9%, P = 0.01) AND RPE (12 +/- 1 VS. 11 +/- 1, P = 0.04). ACCORDING TO ESTABLISHED EXERCISE INTENSITIES, HOT YOGA WAS CLASSIFIED AS LIGHT-INTENSITY EXERCISE BASED ON PERCENTAGE OF MAXIMAL OXYGEN CONSUMPTION BUT MODERATE-INTENSITY EXERCISE BASED ON %HRMAX AND RPE WHILE THERMO-NEUTRAL YOGA WAS CLASSIFIED AS LIGHT-INTENSITY EXERCISE BASED ON PERCENTAGE OF MAXIMAL OXYGEN UPTAKE, %HRMAX, AND RPE. DESPITE THE ADDED HEMODYNAMIC STRESS AND PERCEPTION THAT YOGA IS MORE STRENUOUS IN A HOT ENVIRONMENT, WE OBSERVED SIMILAR OXYGEN CONSUMPTION DURING HOT VERSUS THERMO-NEUTRAL YOGA, CLASSIFYING BOTH EXERCISE MODALITIES AS LIGHT-INTENSITY EXERCISE.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
2 2193  36 THE EFFECTS OF YOGA TRAINING AND A SINGLE BOUT OF YOGA ON DELAYED ONSET MUSCLE SORENESS IN THE LOWER EXTREMITY. THE PURPOSE OF THIS STUDY WAS TO DETERMINE THE EFFECTS OF YOGA TRAINING AND A SINGLE BOUT OF YOGA ON THE INTENSITY OF DELAYED ONSET MUSCLE SORENESS (DOMS). 24 YOGA-TRAINED (YT; N = 12) AND NON-YOGA-TRAINED (CON; N = 12), MATCHED WOMEN VOLUNTEERS WERE ADMINISTERED A DOMS-INDUCING BENCH-STEPPING EXERCISE. MUSCLE SORENESS WAS ASSESSED AT BASELINE, 24, 48, 72, 96, AND 120 HOURS AFTER BENCH-STEPPING USING A VISUAL ANALOG SCALE (VAS). GROUPS WERE ALSO COMPARED ON BODY AWARENESS (BA), FLEXIBILITY USING THE SIT-AND-REACH TEST (SR), AND PERCEIVED EXERTION (RPE). STATISTICAL SIGNIFICANCE WAS ACCEPTED AT P </= 0.05. A 2 X 2 MIXED FACTORIAL ANOVA WITH REPEATED MEASURES AT 24 AND 48 HOURS REVEALED A SIGNIFICANT (P < 0.05) GROUP MAIN EFFECT WITH VAS SCORES GREATER FOR CON THAN YT. PAIRED T-TESTS REVEALED THAT IN YT, VAS SCORES WERE HIGHER BEFORE YOGA CLASS THAN AFTER YOGA CLASS AT 24 HOURS (21.4 [+/- 6.9] MM VS. 11.1 [+/- 4.1] MM; P = 0.02). THE SR WAS GREATER IN YT THAN IN CON (65.0 [+/- 7.9] CM VS. 33.3 [+/- 7.0] CM; P < 0.01); HOWEVER, NO DIFFERENCES WERE FOUND BETWEEN YOGA AND CONTROL IN BA (94.0 [+/- 4.4] UNITS VS. 83.8 [+/- 3.7] UNITS; P = 0.21) OR IN RPE AT 5-MINUTE INTERVALS (2.9 [+/- 0.3], 5.3 [+/- 0.8], 5.8 [+/- 0.9], AND 5.2 [+/- 0.8] VS. 2.5 [+/- 0.3], 4.0 [+/- 0.5], 4.2 [+/- 0.3], AND 4.9 [+/- 0.4]. YOGA TRAINING AND A SINGLE BOUT OF YOGA APPEAR TO ATTENUATE PEAK MUSCLE SORENESS IN WOMEN FOLLOWING A BOUT OF ECCENTRIC EXERCISE. THESE FINDINGS HAVE SIGNIFICANT IMPLICATIONS FOR COACHES, ATHLETES, AND THE EXERCISING PUBLIC WHO MAY WANT TO IMPLEMENT YOGA TRAINING AS A PRESEASON REGIMEN OR SUPPLEMENTAL ACTIVITY TO LESSEN THE SYMPTOMS ASSOCIATED WITH MUSCLE SORENESS.	2004	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
3  995  36 EFFECTS OF HIGH-INTENSITY HATHA YOGA ON CARDIOVASCULAR FITNESS, ADIPOCYTOKINES, AND APOLIPOPROTEINS IN HEALTHY STUDENTS: A RANDOMIZED CONTROLLED STUDY. BACKGROUND: YOGA EXERCISES ARE OFTEN USED AS A FORM OF BODY AND MIND EXERCISE TO INCREASE PERFORMANCE. HOWEVER, KNOWLEDGE ABOUT THE PHYSIOLOGIC EFFECTS OF PERFORMING HIGH-INTENSITY HATHA YOGA EXERCISES OVER A LONGER TIME PERIOD REMAINS LIMITED. OBJECTIVE: TO INVESTIGATE THE EFFECTS OF HIGH-INTENSITY YOGA (HIY) ON CARDIOVASCULAR FITNESS (MAXIMAL OXYGEN CONSUMPTION, ESTIMATED FROM THE COOPER RUNNING TEST), RATINGS OF PERCEIVED EXERTION (RPE), HEART RATE (HR), HEART RATE RECOVERY (HRR), BLOOD PRESSURE (BP), ADIPOCYTOKINES, APOLIPOPROTEIN A1 (APOA1), APOLIPOPROTEIN B (APOB), AND GLYCOSYLATED HEMOGLOBIN (HBA1C) IN HEALTHY STUDENTS. METHODS: THE 44 PARTICIPANTS (38 WOMEN AND 6 MEN; MEDIAN AGE, 25 YEARS [RANGE, 20-39 YEARS]) WERE RANDOMLY ASSIGNED TO AN HIY OR A CONTROL GROUP. THE HIY PROGRAM WAS HELD FOR 6 WEEKS (60 MINUTES ONCE A WEEK). CARDIOVASCULAR FITNESS, RPE, HR, HRR, BP, ADIPOCYTOKINES, HBA1C, APOA1, AND APOB WERE MEASURED AT BASELINE AND AFTER 6 WEEKS IN BOTH GROUPS. RESULTS: HIY HAD NO SIGNIFICANT EFFECTS ON CARDIOVASCULAR FITNESS (MEAN DOSE: 390 MINUTES [RANGE, 210-800 MINUTES]), HR, HRR, BP, OR ANY OF THE BLOOD PARAMETERS. HOWEVER, SECONDARY FINDINGS SHOWED THAT [CORRECTED] APOA1 (1.47 +/- 0.17 TO 1.55 +/- 0.16 G/L; P = 0.03) AND ADIPONECTIN (8.32 +/- 3.32 TO 9.68 +/- 3.83 MG/L; P = 0.003) LEVELS INCREASED SIGNIFICANTLY IN THE HIY GROUP AFTER 6 WEEKS. CONCLUSIONS: SIX WEEKS OF HIY DID NOT SIGNIFICANTLY IMPROVE CARDIOVASCULAR FITNESS. HOWEVER, SECONDARY FINDINGS SHOWED THAT [CORRECTED] APOA1 AND ADIPONECTIN LEVELS INCREASED SIGNIFICANTLY IN THE HIY GROUP. THIS FINDING SUGGESTS THAT HIY MAY HAVE POSITIVE EFFECTS ON BLOOD LIPIDS AND AN ANTI-INFLAMMATORY EFFECT.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
4 1060  35 EFFECTS OF YOGA ON FUNCTIONAL CAPACITY AND WELL BEING. YOGA HAS PROVEN BENEFICIAL EFFECTS ON VARIOUS HEALTH DOMAINS INCLUDING MUSCULOSKELETAL CONDITIONS, CARDIOPULMONARY CONDITIONS THROUGH THE PRACTICE OF ASANA AND PRANAYAMAS AS WELL AS ON MENTAL HEALTH, AS IT IS KNOWN TO ENHANCE THE BODY-AND MIND COORDINATION. THERE IS PAUCITY OF DATA ON THE EFFECT OF YOGA ON FUNCTIONAL CAPACITY IN LITERATURE USING 6 MIN WALK TEST. THE PRESENT STUDY AIMS TO LOOK AT THE EFFECT OF YOGA ON 6-MIN WALKED DISTANCE, RATING OF PERCEIVED EXERTION (RPE), RECOVERY TIME FOLLOWING THE WALK AND STATE OF WELL BEING. THIS IS A HOSPITAL-BASED LONGITUDINAL STUDY WHERE 30 PHYSIOTHERAPY STUDENTS OF THE AGE GROUP 18 - 22 YEARS OF EITHER SEX WERE ENROLLED. SUBJECTS HAVING MUSCULOSKELETAL PROBLEMS, CARDIO RESPIRATORY DISEASE AND THOSE WHO WERE NOT WILLING TO VOLUNTEER WERE EXCLUDED THEY RECEIVED YOGA INTERVENTION IN FORM OF YOGIC PRACTICES WHICH INCLUDED A COMBINATION OF ASANAS, PRANAYAMAS AND OMKAR CHANTING FOR 1 H FOR 30 SESSIONS. A BASELINE 6-MIN WALK TEST WAS CONDUCTED ON SUBJECTS AND THE 6-MIN WALKED DISTANCE, RATING OF PERCEIVED EXERTION (RPE) ON MODIFIED BORG'S SCALE WERE RECORDED. THE BASELINE STATE OF WELL-BEING WAS NOTED USING THE WARWICK- EDINBURGH MENTAL WELL-BEING SCALE AND SIMILAR RECORDING WAS DONE POST INTERVENTION AFTER 30 SESSIONS. OF THE 30 SUBJECTS, THERE WERE NO DROP OUTS AS THESE WERE COMMITTED COLLEGE STUDENTS. OF THEM, 24 WERE FEMALES AND 6 WERE MALES WITH A MEAN AGE OF 21.5 YEARS SD 2.38. STATISTICALLY SIGNIFICANT IMPROVEMENTS WERE OBSERVED IN 6-MIN WALK DISTANCE (P VALUE = 0.000), RPE (P VALUE < 0.000), RECOVERY TIME (P VALUE < 0.000) AND SENSE OF WELL BEING SCORE (P VALUE < 0.000). YOGA PRACTICES ARE BENEFICIAL IN IMPROVING THE FUNCTIONAL CAPACITY IN YOUNG HEALTHY ADULTS. YOGA CAN VERY WELL BE INCORPORATED IN MEDICAL PRACTICE FOR INCREASING THE PATIENT'S FUNCTIONAL CAPACITY, FOR THOSE WHO HAVE LIMITATIONS IN PERFORMING AEROBIC TRAINING DUE TO VARIOUS HEALTH REASONS. THE IMPROVED STATE OF WELL BEING MOTIVATES THE PATIENTS TO ADHERE TO YOGIC PRACTICES.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
5  967  32 EFFECTS OF AEROBIC EXERCISE TRAINING AND YOGA ON THE BAROREFLEX IN HEALTHY ELDERLY PERSONS. IT IS UNCLEAR WHETHER THE AGE-ASSOCIATED REDUCTION IN BAROREFLEX SENSITIVITY IS MODIFIABLE BY EXERCISE TRAINING. THE EFFECTS OF AEROBIC EXERCISE TRAINING AND YOGA, A NON-AEROBIC CONTROL INTERVENTION, ON THE BAROREFLEX OF ELDERLY PERSONS WAS DETERMINED. BAROREFLEX SENSITIVITY WAS QUANTIFIED BY THE ALPHA-INDEX, AT HIGH FREQUENCY (HF; 0.15-0.35 HZ, REFLECTING PARASYMPATHETIC ACTIVITY) AND MID-FREQUENCY (MF; 0.05-0.15 HZ, REFLECTING SYMPATHETIC ACTIVITY AS WELL), DERIVED FROM SPECTRAL AND CROSS-SPECTRAL ANALYSIS OF SPONTANEOUS FLUCTUATIONS IN HEART RATE AND BLOOD PRESSURE. TWENTY-SIX (10 WOMEN) SEDENTARY, HEALTHY, NORMOTENSIVE ELDERLY (MEAN 68 YEARS, RANGE 62-81 YEARS) SUBJECTS WERE STUDIED. FOURTEEN (4 WOMEN) OF THE SEDENTARY ELDERLY SUBJECTS COMPLETED 6 WEEKS OF AEROBIC TRAINING, WHILE THE OTHER 12 (6 WOMEN) SUBJECTS COMPLETED 6 WEEKS OF YOGA. HEART RATE DECREASED FOLLOWING YOGA (69 +/- 8 VS. 61 +/- 7 MIN-1, P < 0.05) BUT NOT AEROBIC TRAINING (66 +/- 8 VS. 63 +/- 9 MIN-1, P = 0.29). VO2 MAX INCREASED BY 11% FOLLOWING YOGA (P < 0.01) AND BY 24% FOLLOWING AEROBIC TRAINING (P < 0.01). NO SIGNIFICANT CHANGE IN ALPHA MF (6.5 +/- 3.5 VS. 6.2 +/- 3.0 MS MMHG-1, P = 0.69) OR ALPHA HF (8.5 +/- 4.7 VS. 8.9 +/- 3.5 MS MMHG-1, P = 0.65) OCCURRED AFTER AEROBIC TRAINING. FOLLOWING YOGA, ALPHA HF (8.0 +/- 3.6 VS. 11.5 +/- 5.2 MS MMHG-1, P < 0.01) BUT NOT ALPHA MF (6.5 +/- 3.0 VS. 7.6 +/- 2.8 MS MMHG-1, P = 0.29) INCREASED. SHORT-DURATION AEROBIC TRAINING DOES NOT MODIFY THE ALPHA-INDEX AT ALPHA MF OR ALPHA HF IN HEALTHY NORMOTENSIVE ELDERLY SUBJECTS. ALPHA HF BUT NOT ALPHA MF INCREASED FOLLOWING YOGA, SUGGESTING THAT THESE PARAMETERS ARE MEASURING DISTINCT ASPECTS OF THE BAROREFLEX THAT ARE SEPARATELY MODIFIABLE.	1997	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
6  993  17 EFFECTS OF HEATED AND THERMONEUTRAL YOGA INTERVENTIONS ON ARTERIAL STIFFNESS IN MIDDLE-AGED ADULTS. THE STUDY INVESTIGATED THE EFFICACY OF 12 WEEKS OF HEATED AND THERMONEUTRAL BIKRAM YOGA IN REDUCING ARTERIAL STIFFNESS IN MIDDLE-AGED ADULTS. FIFTY-FOUR SEDENTARY ADULTS (AGES 40-60 YEARS) COMPLETED 12 WEEKS OF YOGA AT 40.5 DEGREES C (N = 21), YOGA AT 23 DEGREES C (N = 14) OR TIME CONTROL (N = 19). BRACHIAL-ANKLE PULSE WAVE VELOCITY (PWV) WAS NOT SIGNIFICANTLY ALTERED BY HOT OR THERMONEUTRAL YOGA INTERVENTIONS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
7 1693  29 OXYGEN CONSUMPTION DURING VINIYOGA PRACTICE IN ADULTS. CONTEXT: THE PURPOSE OF THIS STUDY WAS TO MEASURE THE OXYGEN CONSUMPTION (VO2) DURING VINIYOGA YOGA MOVEMENTS (ASANAS) AND TO COMPARE VO2 WALKING AMONG ADULTS. METHODS: YOGA PRACTITIONERS (N = 10) WERE RECRUITED TO MEASURE VO2 WHILE AT REST (30 MIN), PRACTICING YOGA (16 MOVEMENTS WITH DIFFERENT VARIATIONS), AND TREADMILL WALKING AT 2 MPH (10 MIN) AND 3 MPH (10 MIN). VO2 WAS MEASURED USING A WHOLE-ROOM INDIRECT CALORIMETRY. EACH YOGA MOVEMENT WAS CATEGORIZED BY BODY ORIENTATION AS STANDING, LYING, AND SITTING. THE DIFFERENCES IN VO2 BETWEEN YOGA AND WALKING WERE EXAMINED USING PEARSON'S CORRELATIONS. DIFFERENCES IN VO2 BETWEEN POSES (STANDING, SITTING, AND LYING) WERE EXAMINED USING LINEAR REGRESSION MODELS. VO2. RESULTS: MEAN YOGA-VO2 FOR THE ENTIRE YOGA SESSION WAS 3.7 (STANDARD DEVIATION [SD] 0.43, RANGE: 4.4-8.9) ML/KG/MIN. YOGA-VO2 VARIED BY BODY ORIENTATION: STANDING = 7.5 (SD = 1.5) ML/KG/MIN, LYING = 5.3 (SD = 1.0) ML/KG/MIN, AND SITTING = 5.4 (SD = 1.1) ML/KG/MIN. AFTER ADJUSTING FOR BODY MASS, FREQUENCY OF YOGA PRACTICE, AND RESTING ENERGY EXPENDITURE, FEMALE GENDER WAS NEGATIVELY ASSOCIATED WITH MEAN YOGA VO2 FOR STANDING (B = -112.19, P < 0.05), LYING (B = -141.87, P < 0.05), AND SITTING (B = -129.96, P < 0.05). MEAN VO2 FOR WALKING 2 MPH WAS COMPARABLE WITH SITTING (R = 0.836, P < 0.05) AND LYING (R = 0.735, P < 0.05) WHEREAS WALKING AT 3 MPH WAS COMPARABLE WITH STANDING (R = 0.718, P < 0.05) AND SITTING (R = 0.760, P < 0.05). CONCLUSION: WE CONCLUDE THAT VO2 DURING YOGA PRACTICE IS COMPARABLE TO VO2 DURING SLOW TREADMILL WALKING AND MAY VARY BASED ON GENDER AND BODY ORIENTATION.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
8 1147  39 ENERGY EXPENDITURE DURING A VINYASA YOGA SESSION. BACKGROUND: VINYASA YOGA HAS BEEN RECENTLY PROMOTED AS ONE OF THE MOST POPULAR MINDFUL EXERCISES TO IMPROVE OVERALL HEALTH, INCLUDING BODY WEIGHT MANAGEMENT. THE PURPOSE OF THIS STUDY WAS TO DETERMINE THE METABOLIC RESPONSE OF 24 MODERATELY TRAINED INDIVIDUALS DURING A 90-MIN GROUP VINYASA YOGA ROUTINE. METHODS: HEART RATE (HR) TIME COURSE OF 12 MALES AND 12 FEMALES (AGE: 39+/-7.33 YEARS) WAS RECORDED DURING TWO GROUP VINYASA YOGA SESSIONS CONSISTED OF FOUR SECTIONS (WARM-UP, HIGH-INTENSITY SURYA NAMASKAR (HSN), NO SURYA NAMASKAR POSTURES, AND COOL-DOWN). MAXIMAL OXYGEN UPTAKE (VO<INF>2PEAK</INF>) AND MAXIMUM HR HAD BEEN ESTIMATED EARLIER AFTER A MAXIMAL TREADMILL TEST. VO<INF>2</INF> DURING VINYASA YOGA SESSIONS WAS ESTIMATED FROM INDIVIDUAL REGRESSION EQUATIONS USING THE RELATIONSHIP OF VO<INF>2</INF> AND HR VALUES DERIVED FROM VO<INF>2PEAK</INF> TEST, WHILE THE METABOLIC RATE (KCAL/MIN) WAS CALCULATED FROM THE RELATIONSHIP OF HR AND KCAL/MIN. TOTAL SESSION ENERGY CONSUMPTION WAS THE AVERAGE VALUE OF THE TWO YOGA SESSIONS. RESULTS: THE 2 (GENDER) X 4 (SECTIONS) MIXED ANOVA REVEALED NO SIGNIFICANT INTERACTION BETWEEN THE TWO FACTORS (P=0.101) FOR THE MEAN METABOLIC RATE (7.1+/-2.6 KCAL/MIN). MEAN METABOLIC RATE THOUGHT WAS HIGHER (P=0.015) IN MALES COMPARED TO FEMALES AT EACH SECTION. ALSO, SIGNIFICANT DIFFERENCES WERE FOUND AMONG THE FOUR VINYASA YOGA SECTIONS (P<0.001) IN THE RATE OF ENERGY EXPENDITURE, WITH HSN PRESENTING THE HIGHEST MEAN VALUES (P<0.05). CONCLUSIONS: IT SEEMS THAT SYSTEMATIC PARTICIPATION IN VINYASA YOGA MAY EFFECTIVELY IMPROVE CARDIORESPIRATORY FITNESS AND PROMOTE BODY WEIGHT LOSS, AS AN ALTERNATIVE METHOD TO TRADITIONAL AEROBIC EXERCISE.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
9 1305  31 HATHA YOGA PRACTICES: ENERGY EXPENDITURE, RESPIRATORY CHANGES AND INTENSITY OF EXERCISE. THE AIM OF THIS STUDY WAS TO CRITICALLY OBSERVE THE ENERGY EXPENDITURE, EXERCISE INTENSITY AND RESPIRATORY CHANGES DURING A FULL YOGA PRACTICE SESSION. OXYGEN CONSUMPTION ([FORMULA: SEE TEXT]), CARBON DIOXIDE OUTPUT ([FORMULA: SEE TEXT]), PULMONARY VENTILATION ([FORMULA: SEE TEXT]E), RESPIRATORY RATE (FR) AND TIDAL VOLUME (VT), WERE MEASURED IN 16 PHYSICAL POSTURE (ASANAS), FIVE YOGA BREATHING MANEUVERS (BM) AND TWO TYPES OF MEDITATION. TWENTY MALE (AGE 27.3 +/- 3.5 YEARS, HEIGHT 166.6 +/- 5.4 CM AND BODY WEIGHT 58.8 +/- 9.6 KG) YOGA INSTRUCTORS WERE STUDIED. THEIR MAXIMAL OXYGEN CONSUMPTION ([FORMULA: SEE TEXT]) WAS RECORDED. THE EXERCISE INTENSITY IN ASANAS WAS EXPRESSED IN PERCENTAGE [FORMULA: SEE TEXT] . IN ASANAS, EXERCISE INTENSITY VARIED FROM 9.9 TO 26.5% OF [FORMULA: SEE TEXT] . HIGHEST ENERGY COST WAS 3.02 KCAL MIN(-1). IN BM HIGHEST [FORMULA: SEE TEXT]E WAS 53.7 +/- 15.5 L MIN(-1). VT WAS 0.97 +/- 0.59, 1.41 +/- 1.27 AND 1.28 +/- L/BREATH WITH CORRESPONDING FR OF 14.0 +/- 5.3, 10.0 +/- 6.35, 10.0 +/- 5.8 BREATHS/MIN. AVERAGE ENERGY EXPENDITURE IN ASANAS, BM AND MEDITATION WERE 2.29, 1.91 AND 1.37 KCAL MIN(-1), RESPECTIVELY. METABOLIC RATE WAS GENERALLY IN THE RANGE OF 1-2 METABOLIC EQUIVALENTS (MET) EXCEPT IN THREE ASANAS WHERE IT WAS >2 MET. [FORMULA: SEE TEXT] WAS 0.27 +/- 0.05 AND 0.24 +/- 0.04 L MIN(-1) IN MEDITATION AND SHAVASANA, RESPECTIVELY. ALTHOUGH YOGIC PRACTICES ARE LOW INTENSITY EXERCISES WITHIN LACTATE THRESHOLD, PHYSICAL PERFORMANCE IMPROVEMENT IS POSSIBLE OWING TO BOTH BETTER ECONOMY OF BREATHING BY BM AND ALSO BY IMPROVEMENT IN CARDIOVASCULAR RESERVE. OTHER FACTORS SUCH AS PSYCHO-PHYSIOLOGICAL AND BETTER RELAXATION MAY CONTRIBUTE TO IT.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
10 1045  38 EFFECTS OF YOGA INTERVENTIONS PRACTISED IN HEATED AND THERMONEUTRAL CONDITIONS ON ENDOTHELIUM-DEPENDENT VASODILATATION: THE BIKRAM YOGA HEART STUDY. NEW FINDINGS: WHAT IS THE CENTRAL QUESTION OF THIS STUDY? DOES THE HEATED PRACTICE ENVIRONMENT ENHANCE THE EFFECTS OF BIKRAM YOGA ON ENDOTHELIUM-DEPENDENT VASODILATATION IN HEALTHY, MIDDLE-AGED ADULTS? WHAT IS THE MAIN FINDING AND ITS IMPORTANCE? THE PRIMARY FINDING FROM THIS INVESTIGATION IS THAT THE HATHA YOGA POSTURES IN THE BIKRAM YOGA SERIES PRODUCE SIMILAR ENHANCEMENTS IN ENDOTHELIUM-DEPENDENT VASODILATATION IN HEALTHY, MIDDLE-AGED ADULTS REGARDLESS OF ENVIRONMENTAL TEMPERATURE. THESE FINDINGS HIGHLIGHT THE EFFICACY OF YOGA POSTURES IN PRODUCING IMPROVEMENTS IN VASCULAR HEALTH AND DOWNPLAY THE NECESSITY OF THE HEATED PRACTICE ENVIRONMENT IN INDUCING VASCULAR ADAPTATIONS. ABSTRACT: WE HAVE PREVIOUSLY DOCUMENTED IMPROVEMENTS IN ENDOTHELIUM-DEPENDENT VASODILATATION WITH A BIKRAM (HOT) YOGA INTERVENTION IN MIDDLE-AGED ADULTS. AT PRESENT, THE EFFECT OF ENVIRONMENTAL TEMPERATURE IN HOT YOGA ON ENDOTHELIAL FUNCTION IS UNKNOWN. THE PURPOSE OF THIS INVESTIGATION WAS TO DETERMINE THE EFFECTS OF BIKRAM YOGA INTERVENTIONS PERFORMED IN HEATED OR THERMONEUTRAL CONDITIONS ON ENDOTHELIUM-DEPENDENT VASODILATATION. FIFTY-TWO SEDENTARY BUT APPARENTLY HEALTHY ADULTS AGED 40-60 YEARS WERE RANDOMLY ASSIGNED TO ONE OF THREE GROUPS: BIKRAM YOGA PRACTISED AT 40.5 DEGREES C (N = 19), BIKRAM YOGA PRACTISED AT 23 DEGREES C (N = 14) OR SEDENTARY TIME CONTROL (N = 19). THE YOGA INTERVENTIONS CONSISTED OF 90 MIN BIKRAM YOGA CLASSES THREE TIMES A WEEK FOR 12 WEEKS. ENDOTHELIUM-DEPENDENT VASODILATATION WAS MEASURED NON-INVASIVELY USING BRACHIAL ARTERY FLOW-MEDIATED DILATATION (FMD). BODY FAT PERCENTAGE DETERMINED VIA DUAL-ENERGY X-RAY ABSORPTIOMETRY WAS SIGNIFICANTLY LOWER IN THE HOT YOGA GROUP AFTER THE INTERVENTION THAN IN THE THERMONEUTRAL YOGA AND CONTROL CONDITIONS. BRACHIAL ARTERY FMD INCREASED (P < 0.05) IN THE THERMONEUTRAL YOGA GROUP AND TENDED TO INCREASE IN THE HOT YOGA GROUP (P = 0.056). NO CHANGES OCCURRED IN THE CONTROL GROUP. THERE WERE NO SIGNIFICANT DIFFERENCES IN FMD CHANGE SCORES BETWEEN GROUPS. WE CONCLUDE THAT BIKRAM YOGA PRACTISED IN THERMONEUTRAL CONDITIONS IMPROVED ENDOTHELIUM-DEPENDENT VASODILATATION IN HEALTHY, MIDDLE-AGED ADULTS. THESE NEW FINDINGS HIGHLIGHT THE EFFECTIVENESS OF HATHA YOGA POSTURES ALONE, IN THE ABSENCE OF A HEATED PRACTICE ENVIRONMENT, IN IMPROVING VASCULAR HEALTH AND ARE OF CLINICAL SIGNIFICANCE GIVEN THE INCREASED PROPENSITY FOR HEAT INTOLERANCE IN AGEING ADULTS.	2018	

11  985  28 EFFECTS OF HATHA YOGA AND OMKAR MEDITATION ON CARDIORESPIRATORY PERFORMANCE, PSYCHOLOGIC PROFILE, AND MELATONIN SECRETION. OBJECTIVES: TO EVALUATE EFFECTS OF HATHA YOGA AND OMKAR MEDITATION ON CARDIORESPIRATORY PERFORMANCE, PSYCHOLOGIC PROFILE, AND MELATONIN SECRETION. SUBJECTS AND METHODS: THIRTY HEALTHY MEN IN THE AGE GROUP OF 25-35 YEARS VOLUNTEERED FOR THE STUDY. THEY WERE RANDOMLY DIVIDED IN TWO GROUPS OF 15 EACH. GROUP 1 SUBJECTS SERVED AS CONTROLS AND PERFORMED BODY FLEXIBILITY EXERCISES FOR 40 MINUTES AND SLOW RUNNING FOR 20 MINUTES DURING MORNING HOURS AND PLAYED GAMES FOR 60 MINUTES DURING EVENING HOURS DAILY FOR 3 MONTHS. GROUP 2 SUBJECTS PRACTICED SELECTED YOGIC ASANAS (POSTURES) FOR 45 MINUTES AND PRANAYAMA FOR 15 MINUTES DURING THE MORNING, WHEREAS DURING THE EVENING HOURS THESE SUBJECTS PERFORMED PREPARATORY YOGIC POSTURES FOR 15 MINUTES, PRANAYAMA FOR 15 MINUTES, AND MEDITATION FOR 30 MINUTES DAILY, FOR 3 MONTHS. ORTHOSTATIC TOLERANCE, HEART RATE, BLOOD PRESSURE, RESPIRATORY RATE, DYNAMIC LUNG FUNCTION (SUCH AS FORCED VITAL CAPACITY, FORCED EXPIRATORY VOLUME IN 1 SECOND, FORCED EXPIRATORY VOLUME PERCENTAGE, PEAK EXPIRATORY FLOW RATE, AND MAXIMUM VOLUNTARY VENTILATION), AND PSYCHOLOGIC PROFILE WERE MEASURED BEFORE AND AFTER 3 MONTHS OF YOGIC PRACTICES. SERIAL BLOOD SAMPLES WERE DRAWN AT VARIOUS TIME INTERVALS TO STUDY EFFECTS OF THESE YOGIC PRACTICES AND OMKAR MEDITATION ON MELATONIN LEVELS. RESULTS: YOGIC PRACTICES FOR 3 MONTHS RESULTED IN AN IMPROVEMENT IN CARDIORESPIRATORY PERFORMANCE AND PSYCHOLOGIC PROFILE. THE PLASMA MELATONIN ALSO SHOWED AN INCREASE AFTER THREE MONTHS OF YOGIC PRACTICES. THE SYSTOLIC BLOOD PRESSURE, DIASTOLIC BLOOD PRESSURE, MEAN ARTERIAL PRESSURE, AND ORTHOSTATIC TOLERANCE DID NOT SHOW ANY SIGNIFICANT CORRELATION WITH PLASMA MELATONIN. HOWEVER, THE MAXIMUM NIGHT TIME MELATONIN LEVELS IN YOGA GROUP SHOWED A SIGNIFICANT CORRELATION (R = 0.71, P < 0.05) WITH WELL-BEING SCORE. CONCLUSION: THESE OBSERVATIONS SUGGEST THAT YOGIC PRACTICES CAN BE USED AS PSYCHOPHYSIOLOGIC STIMULI TO INCREASE ENDOGENOUS SECRETION OF MELATONIN, WHICH, IN TURN, MIGHT BE RESPONSIBLE FOR IMPROVED SENSE OF WELL-BEING.	2004	
                                                                                                                                                                                                                                                                                                                                                                                                                          
12  642  36 DOES PRACTICING HATHA YOGA SATISFY RECOMMENDATIONS FOR INTENSITY OF PHYSICAL ACTIVITY WHICH IMPROVES AND MAINTAINS HEALTH AND CARDIOVASCULAR FITNESS? BACKGROUND: LITTLE IS KNOWN ABOUT THE METABOLIC AND HEART RATE RESPONSES TO A TYPICAL HATHA YOGA SESSION. THE PURPOSES OF THIS STUDY WERE 1) TO DETERMINE WHETHER A TYPICAL YOGA PRACTICE USING VARIOUS POSTURES MEETS THE CURRENT RECOMMENDATIONS FOR LEVELS OF PHYSICAL ACTIVITY REQUIRED TO IMPROVE AND MAINTAIN HEALTH AND CARDIOVASCULAR FITNESS; 2) TO DETERMINE THE RELIABILITY OF METABOLIC COSTS OF YOGA ACROSS SESSIONS; 3) TO COMPARE THE METABOLIC COSTS OF YOGA PRACTICE TO THOSE OF TREADMILL WALKING. METHODS: IN THIS OBSERVATIONAL STUDY, 20 INTERMEDIATE-TO-ADVANCED LEVEL YOGA PRACTITIONERS, AGE 31.4 +/- 8.3 YEARS, PERFORMED AN EXERCISE ROUTINE INSIDE A HUMAN RESPIRATORY CHAMBER (INDIRECT CALORIMETER) WHILE WEARING HEART RATE MONITORS. THE EXERCISE ROUTINE CONSISTED OF 30 MINUTES OF SITTING, 56 MINUTES OF BEGINNER-LEVEL HATHA YOGA ADMINISTERED BY VIDEO, AND 10 MINUTES OF TREADMILL WALKING AT 3.2 AND 4.8 KPH EACH. MEASURES WERE MEAN OXYGEN CONSUMPTION (VO2), HEART RATE (HR), PERCENTAGE PREDICTED MAXIMAL HEART RATE (%MHR), METABOLIC EQUIVALENTS (METS), AND ENERGY EXPENDITURE (KCAL). SEVEN SUBJECTS REPEATED THE PROTOCOL SO THAT MEASUREMENT RELIABILITY COULD BE ESTABLISHED. RESULTS: MEAN VALUES ACROSS THE ENTIRE YOGA SESSION FOR VO2, HR, %MHR, METS, AND ENERGY/MIN WERE 0.6 L/KG/MIN; 93.2 BEATS/MIN; 49.4%; 2.5; AND 3.2 KCAL/MIN; RESPECTIVELY. RESULTS OF THE ICCS (2,1) FOR MEAN VALUES ACROSS THE ENTIRE YOGA SESSION FOR KCAL, METS, AND %MHR WERE 0.979 AND 0.973, AND 0.865, RESPECTIVELY. CONCLUSION: METABOLIC COSTS OF YOGA AVERAGED ACROSS THE ENTIRE SESSION REPRESENT LOW LEVELS OF PHYSICAL ACTIVITY, ARE SIMILAR TO WALKING ON A TREADMILL AT 3.2 KPH, AND DO NOT MEET RECOMMENDATIONS FOR LEVELS OF PHYSICAL ACTIVITY FOR IMPROVING OR MAINTAINING HEALTH OR CARDIOVASCULAR FITNESS. YOGA PRACTICE INCORPORATING SUN SALUTATION POSTURES EXCEEDING THE MINIMUM BOUT OF 10 MINUTES MAY CONTRIBUTE SOME PORTION OF SUFFICIENTLY INTENSE PHYSICAL ACTIVITY TO IMPROVE CARDIO-RESPIRATORY FITNESS IN UNFIT OR SEDENTARY INDIVIDUALS. THE MEASUREMENT OF ENERGY EXPENDITURE ACROSS YOGA SESSIONS IS HIGHLY RELIABLE.	2007	
                                                                                                                                                                                                                                                                                                                                
13 2258  43 THE PHYSIOLOGICAL RESPONSES TO BIKRAM YOGA IN NOVICE AND EXPERIENCED PRACTITIONERS. CONTEXT: BIKRAM YOGA HAS GAINED A LARGE FOLLOWING, POSSIBLY BECAUSE OF WIDESPREAD CLAIMS BOASTING ENERGY EXPENDITURE OF UP TO 1000 CALORIES PER SESSION. HOWEVER, THESE CLAIMS ARE UNFOUNDED BECAUSE NO SCIENTIFIC STUDY HAS INVESTIGATED THE METABOLIC RESPONSE TO A COMPLETE, STANDARDIZED BIKRAM YOGA CLASS. OBJECTIVES: THIS STUDY INTENDS TO DETERMINE ENERGY EXPENDITURE, HEART RATE, AND SWEAT RATE IN NOVICE AND EXPERIENCED PRACTITIONERS FROM A STANDARDIZED BIKRAM YOGA CLASS. SETTING: DATA WERE COLLECTED IN THE ENVIRONMENTAL CHAMBER OF THE EXERCISE PHYSIOLOGY LABORATORY AT SAN DIEGO STATE UNIVERSITY IN CALIFORNIA, USA. PARTICIPANTS: MALE (N = 5) AND FEMALE (N = 19) PARTICIPANTS BETWEEN THE AGES OF 18 AND 57 Y WERE RECRUITED THROUGH FLYERS IN YOGA STUDIOS THROUGHOUT SAN DIEGO. PARTICIPANTS WERE CLASSIFIED AS EXPERIENCED OR NOVICE PRACTITIONERS, HAVING COMPLETED >/=20 OR <20 SESSIONS, RESPECTIVELY. INTERVENTIONS: PARTICIPANTS WERE GUIDED THROUGH A STANDARDIZED 90-MIN YOGA CLASS PERFORMED IN A HOT ENVIRONMENT USING BIKRAM'S STANDARD BEGINNING DIALOGUE, WHILE EXPIRED GAS WAS COLLECTED AND HEART RATE WAS RECORDED. OUTCOME MEASURES: ENERGY EXPENDITURE, CALCULATED VIA OXYGEN UPTAKE, AND HEART RATE WERE DETERMINED FOR EACH POSTURE AND TRANSITION PERIOD. IN ADDITION, SWEAT RATE AND CORE TEMPERATURE WERE RECORDED FOR EACH PARTICIPANT. RESULTS: MEAN (+/-SD) RELATIVE VO2 FOR THE ENTIRE 90-MIN SESSION WAS 9.5 +/- 1.9 ML X KG-1 X MIN-1, RANGING FROM 6.0 TO 12.9 ML X KG-1 X MIN-1. MEAN ABSOLUTE ENERGY EXPENDITURE WAS 286 +/- 72 KCALS, RANGING FROM 179 TO 478 KCALS. INDEPENDENT SAMPLE T TESTS REVEALED SIGNIFICANT DIFFERENCES (P < .05) IN RELATIVE ENERGY EXPENDITURE, HEART RATE, ENDING CORE TEMPERATURE, AND SWEAT RATE BETWEEN EXPERIENCE LEVELS. MEAN RELATIVE ENERGY EXPENDITURE WAS 3.7 +/- 0.5 KCAL/KG IN NOVICE PRACTITIONERS AND 4.7 +/- 0.8 KCAL/KG IN EXPERIENCED PRACTITIONERS. PERCENTAGE OF PREDICTED MAXIMUM HEART RATE AND SWEAT RATE WERE 72.3% +/- 10.6% AND 0.6 +/- 0.2 KG/H IN NOVICE PRACTITIONERS AND 86.4% +/- 5.2% AND 1.1 +/- 0.5 KG/H IN EXPERIENCED PARTICIPANTS. ALL POSTURES WERE CLASSIFIED AS LIGHT-TO-MODERATE INTENSITY ACCORDING TO THE AMERICAN COLLEGE OF SPORTS MEDICINE (ACSM) STANDARDS. CONCLUSIONS: BIKRAM YOGA MEETS REQUIREMENTS FOR EXERCISE OF LIGHT-TO-MODERATE INTENSITY AND, THEORETICALLY, COULD BE USED FOR WEIGHT MAINTENANCE OR WEIGHT LOSS IF PRACTICED SEVERAL TIMES PER WEEK.	2014	
                                                                                    
14 2823  29 YOGA VERSUS AEROBIC ACTIVITY: EFFECTS ON SPIROMETRY RESULTS AND MAXIMAL INSPIRATORY PRESSURE. OBJECTIVE: TO CLARIFY WHETHER, IN HEALTHY INDIVIDUALS, PRACTICING YOGA CAN MODIFY MAXIMAL INSPIRATORY PRESSURE AND SPIROMETRIC INDICES WHEN COMPARED WITH THE PRACTICE OF AEROBIC EXERCISE. MEYHODS: A CONTROLLED CLINICAL TRIAL. A TOTAL OF 31 HEALTHY VOLUNTEERS WERE ALLOCATED TO PRACTICE AEROBIC EXERCISE (N = 15) OR TO PRACTICE YOGA (N = 16). THOSE IN THE FIRST GROUP SERVED AS CONTROLS AND ENGAGED IN AEROBIC EXERCISE FOR 45-60 MINUTES, TWICE A WEEK FOR THREE MONTHS. THOSE IN THE SECOND GROUP PRACTICED SELECTED YOGIC TECHNIQUES, ALSO IN SESSIONS OF 45-60 MINUTES, TWICE A WEEK FOR THREE MONTHS. FORCED VITAL CAPACITY, FORCED EXPIRATORY VOLUME IN ONE SECOND AND MAXIMAL INSPIRATORY PRESSURE WERE MEASURED BEFORE AND AFTER THE THREE MONTHS OF TRAINING. RESULTS: NO SIGNIFICANT ALTERATIONS WERE SEEN IN THE SPIROMETRIC INDICES. A SLIGHT, ALTHOUGH NOT SIGNIFICANT, IMPROVEMENT IN MAXIMAL INSPIRATORY PRESSURE WAS SEEN IN BOTH GROUPS. HOWEVER, THERE WAS A SIGNIFICANT DIFFERENCE, SEEN IN BOTH GENDERS, BETWEEN THE ABSOLUTE DELTA (FINAL VALUE MINUS BASELINE VALUE) OF MAXIMAL INSPIRATORY PRESSURE FOR THE GROUP PRACTICING YOGA AND THAT OBTAINED FOR THE GROUP ENGAGING IN AEROBIC EXERCISE (MALES: 19.5 CM H2O VERSUS 2.8 CM H2O, P = 0.05; FEMALES: 20 CM H2O VERSUS 3.9 CM H2O, P = 0.01). CONCLUSION: NEITHER YOGA NOR AEROBIC EXERCISE PROVIDED A STATISTICALLY SIGNIFICANT IMPROVEMENT IN MAXIMAL INSPIRATORY PRESSURE AFTER THREE MONTHS. HOWEVER, THE ABSOLUTE VARIATION IN MAXIMAL INSPIRATORY PRESSURE WAS GREATER AMONG THOSE PRACTICING YOGA.	2006	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
15 1451  29 INFLUENCE OF INTENSIVE YOGA TRAINING ON PHYSIOLOGICAL CHANGES IN 6 ADULT WOMEN: A CASE REPORT. THE SHORT-TERM EFFECTS OF 4 WEEKS OF INTENSIVE YOGA PRACTICE ON PHYSIOLOGICAL RESPONSES IN SIX HEALTHY ADULT FEMALE VOLUNTEERS WERE MEASURED USING THE MAXIMAL EXERCISE TREADMILL TEST. YOGA PRACTICE INVOLVED DAILY MORNING AND EVENING SESSIONS OF 90 MINUTES EACH. PRE- AND POST-YOGA EXERCISE PERFORMANCE WAS COMPARED. MAXIMAL WORK OUTPUT (WMAX) FOR THE GROUP INCREASED BY 21%, WITH A SIGNIFICANTLY REDUCED LEVEL OF OXYGEN CONSUMPTION PER UNIT WORK BUT WITHOUT A CONCOMITANT SIGNIFICANT CHANGE IN HEART RATE. AFTER INTENSIVE YOGA TRAINING, AT 154 WMIN(-1) (CORRESPONDING TO WMAX OF THE PRE-YOGA MAXIMAL EXERCISE TEST) PARTICIPANTS COULD EXERCISE MORE COMFORTABLY, WITH A SIGNIFICANTLY LOWER HEART RATE (P < 0.05), REDUCED MINUTE VENTILATION (P < 0.05), REDUCED OXYGEN CONSUMPTION PER UNIT WORK (P < 0.05), AND A SIGNIFICANTLY LOWER RESPIRATORY QUOTIENT (P < 0.05). THE IMPLICATIONS FOR THE EFFECT OF INTENSIVE YOGA ON CARDIORESPIRATORY EFFICIENCY ARE DISCUSSED, WITH THE SUGGESTION THAT YOGA HAS SOME TRANSPARENTLY DIFFERENT QUANTIFIABLE PHYSIOLOGICAL EFFECTS TO OTHER EXERCISES.	1997	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
16 1148  31 ENERGY EXPENDITURE IN VINYASA YOGA VERSUS WALKING. BACKGROUND: WHETHER THE ENERGY COST OF VINYASA YOGA MEETS THE CRITERIA FOR MODERATE-TO-VIGOROUS PHYSICAL ACTIVITY HAS NOT BEEN ESTABLISHED. PURPOSE: TO COMPARE ENERGY EXPENDITURE DURING ACUTE BOUTS OF VINYASA YOGA AND 2 WALKING PROTOCOLS. METHODS: PARTICIPANTS (20 MALES, 18 FEMALES) PERFORMED 60-MINUTE SESSIONS OF VINYASA YOGA (YOGA), TREADMILL WALKING AT A SELF-SELECTED BRISK PACE (SELF), AND TREADMILL WALKING AT A PACE THAT MATCHED THE HEART RATE OF THE YOGA SESSION (HR-MATCH). ENERGY EXPENDITURE WAS ASSESSED VIA INDIRECT CALORIMETRY. RESULTS: ENERGY EXPENDITURE WAS SIGNIFICANTLY LOWER IN YOGA COMPARED WITH HR-MATCH (DIFFERENCE = 79.5 +/- 44.3 KCAL; P < .001) AND SELF (DIFFERENCE = 51.7 +/- 62.6 KCAL; P < .001), BUT NOT IN SELF COMPARED WITH HR-MATCH (DIFFERENCE = 27.8 +/- 72.6 KCAL; P = .054). A SIMILAR PATTERN WAS OBSERVED FOR METABOLIC EQUIVALENTS (HR-MATCH = 4.7 +/- 0.8, SELF = 4.4 +/- 0.7, YOGA = 3.6 +/- 0.6; P < .001). ANALYSES USING ONLY THE INITIAL 45 MINUTES FROM EACH OF THE SESSIONS, WHICH EXCLUDED THE RESTORATIVE COMPONENT OF YOGA, SHOWED ENERGY EXPENDITURE WAS SIGNIFICANTLY LOWER IN YOGA COMPARED WITH HR-MATCH (DIFFERENCE = 68.0 +/- 40.1 KCAL; P < .001) BUT NOT COMPARED WITH SELF (DIFFERENCE = 15.1 +/- 48.7 KCAL; P = .189). CONCLUSIONS: YOGA MEETS THE CRITERIA FOR MODERATE-INTENSITY PHYSICAL ACTIVITY. THUS, YOGA MAY BE A VIABLE FORM OF PHYSICAL ACTIVITY TO ACHIEVE PUBLIC HEALTH GUIDELINES AND TO ELICIT HEALTH BENEFITS.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
17  741  29 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
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	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
19 1298  31 HATHA YOGA AND VASCULAR FUNCTION: RESULTS FROM CROSS-SECTIONAL AND INTERVENTIONAL STUDIES. THE AIM OF THIS STUDY WAS TO DETERMINE THE EFFECT OF HATHA YOGA ON ARTERIAL ELASTICITY AND ENDOTHELIAL FUNCTION. FIRST, A CROSS-SECTIONAL STUDY WAS PERFORMED TO DETERMINE WHETHER YOGA PRACTITIONERS WOULD DEMONSTRATE GREATER ARTERIAL COMPLIANCE AND ENDOTHELIUM-DEPENDENT VASODILATION THAN THEIR SEDENTARY PEERS. SECOND, AN INTERVENTION STUDY INVOLVING 13 SEDENTARY MIDDLE-AGED AND OLDER ADULTS (51 +/- 7 YEARS) WAS PERFORMED TO DETERMINE WHETHER 12 WEEKS OF HATHA YOGA WOULD ELICIT INCREASES IN ARTERIAL COMPLIANCE AND ENDOTHELIAL FUNCTION. IN THE CROSS-SECTIONAL STUDY INVOLVING A TOTAL OF 34 SUBJECTS, THERE WERE NO GROUP DIFFERENCES IN BODY FATNESS, BLOOD LIPID AND LIPOPROTEIN CONCENTRATIONS, CAROTID ARTERY COMPLIANCE OR BRACHIAL ARTERY FLOW-MEDIATED DILATION (FMD). HEMOGLOBIN A1C WAS LOWER IN YOGA PRACTITIONERS THAN IN SEDENTARY ADULTS (P < 0.05). TOTAL CHOLESTEROL AND HEMOGLOBIN A1C DECREASED AFTER THE INTERVENTION (P < 0.05) WHILE CAROTID ARTERY COMPLIANCE AND BRACHIAL ARTERY FMD DID NOT CHANGE. THE RESULTS OF BOTH CROSS-SECTIONAL AND INTERVENTIONAL STUDIES INDICATE THAT REGULAR PRACTICE OF HATHA YOGA IS NOT ASSOCIATED WITH IMPROVEMENTS IN VASCULAR FUNCTIONS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
20 1638  27 MODULATION OF CARDIOVASCULAR RESPONSE TO EXERCISE BY YOGA TRAINING. THIS STUDY REPORTS THE EFFECTS OF YOGA TRAINING ON CARDIOVASCULAR RESPONSE TO EXERCISE AND THE TIME COURSE OF RECOVERY AFTER THE EXERCISE. CARDIOVASCULAR RESPONSE TO EXERCISE WAS DETERMINED BY HARVARD STEP TEST USING A PLATFORM OF 45 CM HEIGHT. THE SUBJECTS WERE ASKED TO STEP UP AND DOWN THE PLATFORM AT A RATE OF 30/MIN FOR A TOTAL DURATION OF 5 MIN OR UNTIL FATIGUE, WHICHEVER WAS EARLIER. HEART RATE (HR) AND BLOOD PRESSURE RESPONSE TO EXERCISE WERE MEASURED IN SUPINE POSITION BEFORE EXERCISE AND AT 1, 2, 3, 4, 5, 7 AND 10 MINUTES AFTER THE EXERCISE. RATE-PRESSURE PRODUCT [RPP = (HR X SP)/100] AND DOUBLE PRODUCT (DO P = HR X MP), WHICH ARE INDICES OF WORK DONE BY THE HEART WERE ALSO CALCULATED. EXERCISE PRODUCED A SIGNIFICANT INCREASE IN HR, SYSTOLIC PRESSURE, RPP & DOP AND A SIGNIFICANT DECREASE IN DIASTOLIC PRESSURE. AFTER TWO MONTHS OF YOGA TRAINING, EXERCISE-INDUCED CHANGES IN THESE PARAMETERS WERE SIGNIFICANTLY REDUCED. IT IS CONCLUDED THAT AFTER YOGA TRAINING A GIVEN LEVEL OF EXERCISE LEADS TO A MILDER CARDIOVASCULAR RESPONSE, SUGGESTING BETTER EXERCISE TOLERANCE.	2004
