1 1147 146 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
2  992  34 EFFECTS OF HATHA YOGA PRACTICE ON THE HEALTH-RELATED ASPECTS OF PHYSICAL FITNESS. TEN HEALTHY, UNTRAINED VOLUNTEERS (NINE FEMALES AND ONE MALE), RANGING IN AGE FROM 18-27 YEARS, WERE STUDIED TO DETERMINE THE EFFECTS OF HATHA YOGA PRACTICE ON THE HEALTH-RELATED ASPECTS OF PHYSICAL FITNESS, INCLUDING MUSCULAR STRENGTH AND ENDURANCE, FLEXIBILITY, CARDIORESPIRATORY FITNESS, BODY COMPOSITION, AND PULMONARY FUNCTION. SUBJECTS WERE REQUIRED TO ATTEND A MINIMUM OF TWO YOGA CLASSES PER WEEK FOR A TOTAL OF 8 WEEKS. EACH YOGA SESSION CONSISTED OF 10 MINUTES OF PRANAYAMAS (BREATH-CONTROL EXERCISES), 15 MINUTES OF DYNAMIC WARM-UP EXERCISES, 50 MINUTES OF ASANAS (YOGA POSTURES), AND 10 MINUTES OF SUPINE RELAXATION IN SAVASANA (CORPSE POSE). THE SUBJECTS WERE EVALUATED BEFORE AND AFTER THE 8-WEEK TRAINING PROGRAM. ISOKINETIC MUSCULAR STRENGTH FOR ELBOW EXTENSION, ELBOW FLEXION, AND KNEE EXTENSION INCREASED BY 31%, 19%, AND 28% (P<0.05), RESPECTIVELY, WHEREAS ISOMETRIC MUSCULAR ENDURANCE FOR KNEE FLEXION INCREASED 57% (P<0.01). ANKLE FLEXIBILITY, SHOULDER ELEVATION, TRUNK EXTENSION, AND TRUNK FLEXION INCREASED BY 13% (P<0.01), 155% (P<0.001), 188% (P<0.001), AND 14% (P<0.05), RESPECTIVELY. ABSOLUTE AND RELATIVE MAXIMAL OXYGEN UPTAKE INCREASED BY 7% AND 6%, RESPECTIVELY (P<0.01). THESE FINDINGS INDICATE THAT REGULAR HATHA YOGA PRACTICE CAN ELICIT IMPROVEMENTS IN THE HEALTH-RELATED ASPECTS OF PHYSICAL FITNESS.

3  659  45 EFFECT OF 11 MONTHS OF YOGA TRAINING ON CARDIORESPIRATORY RESPONSES DURING THE ACTUAL PRACTICE OF SURYA NAMASKAR. BACKGROUND: SURYA NAMASKAR (SN), A POPULAR TRADITIONAL INDIAN YOGIC PRACTICE, INCLUDES PRACTICING 12 PHYSICAL POSTURES WITH ALTERNATE FORWARD AND BACKWARD BENDING MOVEMENT OF THE BODY ALONG WITH DEEP BREATHING MANEUVERS. THE PRACTICE OF SN HAS BECOME POPULAR AMONG YOGA PRACTITIONERS AND OTHER FITNESS CONSCIOUS PEOPLE. THE LONG-TERM EFFECT OF PRACTICING SN AND OTHER YOGIC PRACTICES ON CARDIORESPIRATORY RESPONSES DURING SN ARE LACKING. AIM: THE PRESENT STUDY WAS CONDUCTED TO STUDY THE EFFECT OF YOGIC TRAINING ON VARIOUS CARDIORESPIRATORY RESPONSES DURING THE SN PRACTICE IN YOGA TRAINEES AFTER A TIME INTERVAL OF 3, 6, AND 11 MONTHS. MATERIALS AND METHODS: THE PRESENT STUDY WAS CONDUCTED ON 9 HEALTHY MALE ARMY SOLDIERS WHO UNDERWENT TRAINING IN VARIOUS YOGA POSTURES INCLUDING SN, MEDITATION, AND PRANAYAMA FOR 1 H DAILY FOR 11 MONTHS. FIRST, SECOND, AND THIRD PHASE OF THE STUDY WAS CONDUCTED IN THE LABORATORY AFTER COMPLETION OF 3, 6, AND 11 MONTHS OF THE YOGA TRAINING. THE PARTICIPANTS PERFORMED SN ALONG WITH OTHER YOGIC PRACTICES IN THE LABORATORY AS PER THEIR DAILY PRACTICE SCHEDULE. THE CARDIORESPIRATORY RESPONSES OF THE VOLUNTEERS WERE RECORDED DURING ACTUAL PRACTICE OF SN. STATISTICAL ANALYSIS: ONE-WAY REPEATED MEASURE ANOVA FOLLOWED BY TUKEY HSD. RESULTS: OXYGEN CONSUMPTION AND HEART RATE DURING ACTUAL PRACTICE OF SN WAS 0.794 +/- 0.252, 0.738 +/- 0.229, AND 0.560 +/- 0.165 L/MIN AND 92.1 +/- 11.6, 97.9 +/- 7.3 AND 87.4 +/- 9.2 BEATS/MIN RESPECTIVELY AT 1(ST) , 2(ND) , AND 3(RD) PHASE OF YOGA TRAINING. MINUTE VENTILATION AND TIDAL VOLUME ALSO REDUCED FROM 19.9 +/- 4.65 TO 17.8 +/- 4.41 L/MIN AND 1.091 +/- 0.021 TO 0.952 L/BREATH FROM 1(ST) PHASE TO 3(RD) PHASE OF YOGA TRAINING. HOWEVER, RESPIRATORY PARAMETERS LIKE BREATHING RATE (FR) DID NOT SHOW ANY REDUCTION ACROSS THE THREE PHASES. CONCLUSION: THE RESULTS OF THE PRESENT STUDY INDICATED THAT YOGIC TRAINING CAUSED CONDITIONING OF CARDIORESPIRATORY PARAMETERS EXCEPT FR, WHICH DID NOT REDUCE ACROSS THREE PHASES OF TRAINING.	2014	
                                                                                                                                   
4 1451  34 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
5  985  38 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	
                                                                                          
6  943  35 EFFECTS OF A 12-WEEK HATHA YOGA INTERVENTION ON CARDIORESPIRATORY ENDURANCE, MUSCULAR STRENGTH AND ENDURANCE, AND FLEXIBILITY IN HONG KONG CHINESE ADULTS: A CONTROLLED CLINICAL TRIAL. OBJECTIVE. TO EXAMINE THE EFFECTS OF A 12-WEEK HATHA YOGA INTERVENTION ON CARDIORESPIRATORY ENDURANCE, MUSCULAR STRENGTH AND ENDURANCE, AND FLEXIBILITY IN CHINESE ADULTS. METHODS. 173 ADULTS (AGED 52.0 +/- 7.5 YEARS) WERE ASSIGNED TO EITHER THE YOGA INTERVENTION GROUP (N = 87) OR THE WAITLIST CONTROL GROUP (N = 86). 19 DROPPED OUT FROM THE STUDY. PRIMARY OUTCOMES WERE CHANGES IN CARDIORESPIRATORY ENDURANCE (RESTING HEART RATE (HR) AND MAXIMAL OXYGEN UPTAKE (VO2MAX)), MUSCULAR STRENGTH AND ENDURANCE (CURL-UP AND PUSH-UP TESTS), AND LOWER BACK AND HAMSTRING FLEXIBILITY (THE MODIFIED BACK-SAVER SIT-AND-REACH (MBS) TEST). RESULTS. COMPARED TO CONTROLS, THE YOGA GROUP ACHIEVED SIGNIFICANT IMPROVEMENTS IN VO2MAX (P < 0.01), CURL-UP (P < 0.05) AND PUSH-UP (P < 0.001) TESTS, AND THE MBS LEFT AND RIGHT LEG TESTS (BOTH P < 0.001) IN BOTH GENDERS. SIGNIFICANT CHANGE WAS ALSO FOUND FOR RESTING HR BETWEEN GROUPS IN WOMEN (P < 0.05) BUT NOT IN MEN. FURTHER ANALYSIS COMPARING PARTICIPANTS BETWEEN YOUNGER AND OLDER SUBGROUPS YIELDED SIMILAR FINDINGS, EXCEPT THAT THE OLDER PARTICIPANTS IN THE YOGA GROUP FAILED TO IMPROVE RESTING HR OR THE CURL-UP TEST VERSUS CONTROL. ADHERENCE (89%) AND ATTENDANCE (94%) WERE HIGH. NO SERIOUS ADVERSE EVENTS OCCURRED. CONCLUSION. A 12-WEEK HATHA YOGA INTERVENTION HAS FAVORABLE EFFECTS ON CARDIORESPIRATORY ENDURANCE, MUSCULAR STRENGTH AND ENDURANCE, AND FLEXIBILITY IN CHINESE ADULTS.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
7  675  30 EFFECT OF A SIX-MONTH YOGA EXERCISE INTERVENTION ON FITNESS OUTCOMES FOR BREAST CANCER SURVIVORS. YOGA-BASED EXERCISE HAS PROVEN TO BE BENEFICIAL FOR PRACTITIONERS, INCLUDING CANCER SURVIVORS. THIS STUDY REPORTS ON THE IMPROVEMENTS IN PHYSICAL FITNESS FOR 20 BREAST CANCER SURVIVORS WHO PARTICIPATED IN A SIX-MONTH YOGA-BASED EXERCISE PROGRAM (YE). RESULTS ARE COMPARED TO A COMPREHENSIVE EXERCISE (CE) PROGRAM GROUP AND A COMPARISON (C) EXERCISE GROUP WHO CHOSE THEIR OWN EXERCISES. "PRE" AND "POST" FITNESS ASSESSMENTS INCLUDED MEASURES OF ANTHROPOMETRICS, CARDIORESPIRATORY CAPACITY, STRENGTH AND FLEXIBILITY. DESCRIPTIVE STATISTICS, EFFECT SIZE (D), DEPENDENT SAMPLE 'T' TESTS FOR ALL OUTCOME MEASURES WERE CALCULATED FOR THE YE GROUP. SIGNIFICANT IMPROVEMENTS INCLUDED: DECREASED % BODY FAT (-3.00%, D = -0.44, P < 0.001); INCREASED SIT TO STAND LEG STRENGTH REPETITIONS (2.05, D = 0.48, P = 0.003); FORWARD REACH (3.59 CM, D = 0.61, P = 0.01); AND RIGHT ARM SAGITTAL RANGE OF MOTION (6.50 DEGREES , D = 0.92, P = 0.05). TO COMPARE YE OUTCOMES WITH THE OTHER TWO GROUPS, A ONE-WAY ANALYSIS OF VARIANCE (ANOVA) WAS USED. YE PARTICIPANTS SIGNIFICANTLY OUTPERFORMED C PARTICIPANTS ON "FORWARD REACH" (3.59 CM GAINED VERSUS -2.44 CM LOST), (P = 0.009) AND OUTPERFORMED CE PARTICIPANTS (3.59 CM GAINED VERSUS 1.35 CM GAINED), BUT NOT STATISTICALLY SIGNIFICANT. OUR RESULTS SUPPORT YOGA-BASED EXERCISE MODIFIED FOR BREAST CANCER SURVIVORS AS SAFE AND EFFECTIVE.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
8  436  34 CARDIORESPIRATORY AND METABOLIC CHANGES DURING YOGA SESSIONS: THE EFFECTS OF RESPIRATORY EXERCISES AND MEDITATION PRACTICES. THE NOVELTY OF THIS STUDY WAS TO INVESTIGATE THE CHANGES IN CARDIORESPIRATORY AND METABOLIC INTENSITY BROUGHT ABOUT BY THE PRACTICE OF PRANAYAMAS (BREATHING EXERCISES OF YOGA) AND MEDITATION DURING THE SAME HATHA-YOGA SESSION. THE TECHNIQUE APPLIED WAS THE ONE ADVOCATED BY THE HATHA-YOGA SYSTEM. NINE YOGA INSTRUCTORS-FIVE FEMALES AND FOUR MALES, MEAN AGE OF 44+/-11, 6, WERE SUBJECTED TO ANALYSIS OF THE GASES EXPIRED DURING THREE DISTINCT PERIODS OF 30 MIN: REST, RESPIRATORY EXERCISES AND MEDITATIVE PRACTICE. A METABOLIC OPEN CIRCUIT COMPUTERIZED SYSTEM WAS APPLIED (VO2000, MEDGRAPHICS-USA). THE OXYGEN UPTAKE (VO(2)) AND THE CARBON DIOXIDE OUTPUT (VCO(2)) WERE STATISTICALLY DIFFERENT (P <OR= 0.05) DURING MEDITATION AND PRANAYAMA PRACTICES WHEN COMPARED WITH REST. THE HEART RATE ALSO SUFFERED RELEVANT REDUCTIONS WHEN RESULTS AT REST WERE COMPARED WITH THOSE DURING MEDITATION. A SMALLER PROPORTION OF LIPIDS WAS METABOLIZED DURING MEDITATION PRACTICE COMPARED WITH REST. THE RESULTS SUGGEST THAT THE MEDITATION USED IN THIS STUDY REDUCES THE METABOLIC RATE WHEREAS THE SPECIFIC PRANAYAMA TECHNIQUE IN THIS STUDY INCREASES IT WHEN COMPARED WITH THE REST STATE.	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
9  642  50 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	

10  438  27 CARDIOVASCULAR AND RESPIRATORY EFFECT OF YOGIC SLOW BREATHING IN THE YOGA BEGINNER: WHAT IS THE BEST APPROACH? SLOW BREATHING INCREASES CARDIAC-VAGAL BAROREFLEX SENSITIVITY (BRS), IMPROVES OXYGEN SATURATION, LOWERS BLOOD PRESSURE, AND REDUCES ANXIETY. WITHIN THE YOGA TRADITION SLOW BREATHING IS OFTEN PAIRED WITH A CONTRACTION OF THE GLOTTIS MUSCLES. THIS RESISTANCE BREATH "UJJAYI" IS PERFORMED AT VARIOUS RATES AND RATIOS OF INSPIRATION/EXPIRATION. TO TEST WHETHER UJJAYI HAD ADDITIONAL POSITIVE EFFECTS TO SLOW BREATHING, WE COMPARED BRS AND VENTILATORY CONTROL UNDER DIFFERENT BREATHING PATTERNS (EQUAL/UNEQUAL INSPIRATION/EXPIRATION AT 6 BREATH/MIN, WITH/WITHOUT UJJAYI), IN 17 YOGA-NAIVE YOUNG HEALTHY PARTICIPANTS. BRS INCREASED WITH SLOW BREATHING TECHNIQUES WITH OR WITHOUT EXPIRATORY UJJAYI (P < 0.05 OR HIGHER) EXCEPT WITH INSPIRATORY + EXPIRATORY UJJAYI. THE MAXIMAL INCREASE IN BRS AND DECREASE IN BLOOD PRESSURE WERE FOUND IN SLOW BREATHING WITH EQUAL INSPIRATION AND EXPIRATION. THIS CORRESPONDED WITH A SIGNIFICANT IMPROVEMENT IN OXYGEN SATURATION WITHOUT INCREASE IN HEART RATE AND VENTILATION. UJJAYI SHOWED SIMILAR INCREASE IN OXYGEN SATURATION BUT SLIGHTLY LESSER IMPROVEMENT IN BAROREFLEX SENSITIVITY WITH NO CHANGE IN BLOOD PRESSURE. THE SLOW BREATHING WITH EQUAL INSPIRATION AND EXPIRATION SEEMS THE BEST TECHNIQUE FOR IMPROVING BAROREFLEX SENSITIVITY IN YOGA-NAIVE SUBJECTS. THE EFFECTS OF UJJAYI SEEMS DEPENDENT ON INCREASED INTRATHORACIC PRESSURE THAT REQUIRES GREATER EFFORT THAN NORMAL SLOW BREATHING.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
11  727  40 EFFECT OF LONG-TERM REGULAR YOGA ON PHYSICAL HEALTH OF YOGA PRACTITIONERS. BACKGROUND: YOGA IS A PHYSICAL, MENTAL, AND SPIRITUAL DISCIPLINE. THE EFFECT OF YOGA ON MENTAL HEALTH HAS BEEN STUDIED EXTENSIVELY IN INDIA BUT LESS IN THE CONTEXT OF PHYSICAL HEALTH. OBJECTIVE: THE OBJECTIVE WAS TO EXPLORE THE EFFECT OF LONG-TERM REGULAR YOGA ON PHYSICAL HEALTH OF YOGA PRACTITIONERS. MATERIALS AND METHODS: IT WAS AN INTERVENTIONAL STUDY. INCLUSION CRITERIA WERE STUDENTS WHO ENROLLED FOR 1-YEAR DIPLOMA COURSE AT THE YOGA CENTER. EXCLUSION CRITERIA WERE NONREGULAR YOGA PRACTITIONERS DURING THE COURSE. PHYSICAL HEALTH PARAMETERS CONSIDERED FOR ASSESSMENT BEFORE AND AFTER THE YOGA COURSE WERE PULMONARY FUNCTION TESTS, MAXIMUM OXYGEN CONSUMPTION (VO2 MAX) USING BRUCE TREADMILL TEST, FLEXIBILITY, BODY COMPOSITION ANALYSIS, AND HEMOGLOBIN LEVEL. PAIRED SAMPLE T-TEST AND CHI-SQUARE TEST WERE USED FOR STATISTICAL ANALYSIS. RESULTS: THE AEROBIC CAPACITY IMPROVED SIGNIFICANTLY IN TERMS OF MEAN (STANDARD DEVIATION [SD]) FORCED VITAL CAPACITY (P < 0.001), FORCED EXPIRATION VOLUME AT THE END OF THE FIRST SECOND (P < 0.001) AS WELL AS PEAK EXPIRATORY FLOW RATE (P = 0.04). THE MEAN (SD) FLEXIBILITY SCORE IMPROVED SIGNIFICANTLY (P < 0.001). SIMILARLY, THE ENDURANCE IMPROVED SIGNIFICANTLY IN TERMS OF MEAN (SD) VO2 MAX (< 0.001) AND TREADMILL TIME (P < 0.001). THERE WAS NO SIGNIFICANT CHANGE IN BODY COMPOSITION AND HEMOGLOBIN LEVEL. CONCLUSIONS: REGULAR YOGA PRACTITIONERS DEMONSTRATED THE IMPROVEMENT IN PULMONARY FUNCTIONS, CARDIORESPIRATORY FITNESS, ENDURANCE, AND FLEXIBILITY.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
12 1759  41 POSITIVE EFFECT OF YOGA ON CARDIORESPIRATORY FITNESS: A PILOT STUDY. INTRODUCTION: CARDIOVASCULAR DISEASE (CVD) IS THE LEADING CAUSE OF DEATH IN DEVELOPED COUNTRIES. AN INTEGRAL PART OF PRIMARY PREVENTION IS PHYSICAL ACTIVITY. ONE FORM OF PHYSICAL ACTIVITY TO BE POTENTIALLY USED IS YOGA, BUT THIS ACTIVITY IS ASSOCIATED WITH LOWER ENERGY EXPENDITURE THAN THAT RECOMMENDED FOR PREVENTION. THE STUDY AIMED AT ASSESSING THE EFFECT OF REGULAR YOGA SESSIONS ON THE AEROBIC CAPACITY OF THE PRACTITIONERS AND COMPARING IT WITH THE NORMAL POPULATION PERFORMING PHYSICAL ACTIVITY RECOMMENDED BY GUIDELINES. MATERIALS AND METHODS: FIFTY-EIGHT PERSONS (16 MALES) WITH A MEAN AGE OF 50.0 +/- 11.06 YEARS COMPRISING THE YOGA GROUP PRACTICED YOGA FOR AT LEAST 1 H A DAY FOR OVER 2 YEARS. THEY UNDERWENT SPIROERGOMETRY UNDER MAXIMAL EXERCISE TESTING TO ASSESS BASIC PERFORMANCE PARAMETERS. THEIR RESULTS WERE COMPARED WITH THOSE IN 54 AGE-MATCHED CONTROLS (16 MALES MEAN AGE OF 48 +/- 11.86 YEARS PERFORMING A REGULAR AEROBIC PHYSICAL ACTIVITY FOR AT LEAST 7 H A WEEK. RESULTS: THE YOGA GROUP HAD STATISTICALLY SIGNIFICANTLY HIGHER MAXIMUM PERFORMANCE PER KILOGRAM (P = 0.007) AND MAXIMUM OXYGEN CONSUMPTION PER KILOGRAM PER MINUTE (P = 0.028). CONCLUSIONS: DESPITE LOW ENERGY EXPENDITURE, YOGA PRACTICES ARE BETTER IN SOME CARDIORESPIRATORY FITNESS PARAMETERS THAN OTHER AEROBIC ACTIVITIES RECOMMENDED BY CURRENT GUIDELINES FOR CVD PREVENTION.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
13 1018  36 EFFECTS OF SIX MONTHS OF YOGA ON INFLAMMATORY SERUM MARKERS PROGNOSTIC OF RECURRENCE RISK IN BREAST CANCER SURVIVORS. YOGA-BASED EXERCISE HAS PROVEN TO BE BENEFICIAL FOR PRACTITIONERS, INCLUDING CANCER SURVIVORS. THIS STUDY REPORTS ON THE EFFECT ON INFLAMMATORY BIOLOGICAL MARKERS FOR 20 BREAST CANCER SURVIVORS WHO PARTICIPATED IN A SIX-MONTH YOGA-BASED (YE) EXERCISE PROGRAM. RESULTS ARE COMPARED TO A COMPREHENSIVE EXERCISE (CE) PROGRAM GROUP AND A COMPARISON (C) EXERCISE GROUP WHO CHOSE THEIR OWN EXERCISES. "PRE" AND "POST" ASSESSMENTS INCLUDED MEASURES OF ANTHROPOMETRICS, CARDIORESPIRATORY CAPACITY, AND INFLAMMATORY MARKERS INTERLEUKIN 6 (IL-6), INTERLEUKIN 8 (IL-8), TUMOR NECROSIS FACTOR ALPHA (TNFALPHA) AND C-REACTIVE PROTEIN (CRP). DESCRIPTIVE STATISTICS, EFFECT SIZE (D), AND DEPENDENT SAMPLE 'T' TESTS FOR ALL OUTCOME MEASURES WERE CALCULATED FOR THE YE GROUP. SIGNIFICANT IMPROVEMENTS WERE SEEN IN DECREASED % BODY FAT, (-3.00%, D = -0.44, P = <.001) BUT NOT IN CARDIORESPIRATORY CAPACITY OR IN INFLAMMATORY SERUM MARKERS. TO COMPARE YE OUTCOMES WITH THE OTHER TWO GROUPS, A ONE-WAY ANALYSIS OF CO-VARIANCE (ANCOVA) WAS USED, CONTROLLING FOR AGE, BMI, CARDIORESPIRATORY CAPACITY AND SERUM MARKER BASELINE VALUES. WE FOUND NO DIFFERENCES BETWEEN GROUPS. MOREOVER, WE DID NOT SEE SIGNIFICANT CHANGES IN ANY INFLAMMATORY MARKER FOR ANY GROUP. OUR RESULTS SUPPORT THE EFFECTIVENESS OF YOGA-BASED EXERCISE MODIFIED FOR BREAST CANCER SURVIVORS FOR IMPROVING BODY COMPOSITION. LARGER STUDIES ARE NEEDED TO DETERMINE IF THERE ARE SIGNIFICANT CHANGES IN INFLAMMATORY SERUM MARKERS AS A RESULT OF SPECIFIC EXERCISE MODALITIES.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
14 1305  39 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
15  751  17 EFFECT OF SHORT TERM YOGA PRACTICE ON VENTILATORY FUNCTION TESTS. TWENTYFIVE NORMAL MALE VOLUNTEERS UNDERGOING A TEN WEEKS COURSE IN THE PRACTICE OF YOGA HAVE BEEN STUDIED BY SOME PARAMETERS OF VENTILATORY FUNCTIONS TESTS. THE OBSERVATIONS RECORDED AT THE END OF TEN WEEKS OF THE COURSE HAVE SHOWN IMPROVED VENTILATORY FUNCTIONS IN THE FORM OF LOWERED RESPIRATORY RATE, INCREASED FORCED VITAL CAPACITY, FEV1, MAXIMUM BREATHING CAPACITY AND BREATH HOLDING TIME, WHILE TIDAL VOLUME AND %FEV1, DID NOT REVEAL ANY SIGNIFICANT CHANGE. THUS, A COMBINED PRACTICE OF YOGA SEEMS TO BE BENEFICIAL ON RESPIRATORY EFFICIENCY.	1988	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
16  880  28 EFFECT OF YOGA TRAINING ON HANDGRIP, RESPIRATORY PRESSURES AND PULMONARY FUNCTION. ALTHOUGH THERE ARE A NUMBER OF REPORTS ON THE EFFECT OF YOGA TRAINING ON PULMONARY FUNCTIONS, VERY FEW STUDIES HAVE BEEN UNDERTAKEN ON THE EFFECT OF YOGA TRAINING ON RESPIRATORY PRESSURES AND HANDGRIP ENDURANCE. HENCE THE PRESENT WORK WAS PLANNED TO STUDY THE EFFECT OF YOGA TRAINING ON HAND GRIP STRENGTH (HGS), HAND GRIP ENDURANCE (HGE), MAXIMUM EXPIRATORY PRESSURE (MEP), MAXIMUM INSPIRATORY PRESSURE (MIP), FORCED EXPIRATORY VOLUME (FEV), FORCED EXPIRATORY VOLUME IN FIRST SECOND (FEV1) AND PEAK EXPIRATORY FLOW RATE (PEFR). 20 SCHOOL CHILDREN IN THE AGE GROUP OF 12 TO 15 YEARS WERE GIVEN YOGA TRAINING (ASANS AND PRANAYAMS) FOR 6 MONTHS. 20 AGE AND GENDER-MATCHED STUDENTS FORMED THE CONTROL GROUP. YOGA TRAINING PRODUCED STATISTICALLY SIGNIFICANT (P < 0.05) INCREASE IN HGS AND HGE. MEP, MIP, FEV, FEV1 AND PEFR ALSO INCREASED SIGNIFICANTLY (P < 0.001) AFTER THE YOGA TRAINING. IN CONTRAST, THE INCREASE IN THESE PARAMETERS IN THE CONTROL GROUP WAS STATISTICALLY INSIGNIFICANT. OUR STUDY SHOWS THAT YOGA TRAINING FOR 6 MONTHS IMPROVES LUNG FUNCTION, STRENGTH OF INSPIRATORY AND EXPIRATORY MUSCLES AS WELL AS SKELETAL MUSCLE STRENGTH AND ENDURANCE. IT IS SUGGESTED THAT YOGA BE INTRODUCED AT SCHOOL LEVEL IN ORDER TO IMPROVE PHYSIOLOGICAL FUNCTIONS, OVERALL HEALTH AND PERFORMANCE OF STUDENTS.	2003	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
17 2823  34 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
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	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
19 1691  28 OXYGEN CONSUMPTION AND RESPIRATION DURING AND AFTER TWO YOGA RELAXATION TECHNIQUES. CYCLIC MEDITATION (CM) IS A TECHNIQUE WHICH COMBINES "STIMULATING" AND "CALMING" PRACTICES, BASED ON A STATEMENT IN ANCIENT YOGA TEXTS SUGGESTING THAT SUCH A COMBINATION MAY BE ESPECIALLY HELPFUL TO REACH A STATE OF MENTAL EQUILIBRIUM. THE OXYGEN CONSUMPTION, BREATH RATE AND BREATH VOLUME OF 50 MALE VOLUNTEERS (GROUP MEAN AGE+/-SD, 27+/-6.3 YEARS) WERE ASSESSED BEFORE, DURING, AND AFTER SESSIONS OF CM AND SESSIONS OF SUPINE REST IN THE CORPSE POSTURE (SHAVASANA, SH). THE SESSIONS WERE ONE DAY APART AND THE ORDER WAS ALTERNATED. THE OXYGEN CONSUMPTION, BREATH RATE AND BREATH VOLUME INCREASED DURING THE "STIMULATING" PRACTICES OF CM, RETURNED TO THE BASELINE DURING THE "CALMING" PRACTICES, AND THE OXYGEN CONSUMPTION DECREASED BY 19.3 PERCENT BELOW BASELINE VALUES AFTER CM. DURING THE SH SESSION THE OXYGEN CONSUMPTION, BREATH RATE AND BREATH VOLUME REDUCED; HOWEVER THE DECREASE IN OXYGEN CONSUMPTION AFTER SH WAS LESS THAN AFTER CM (I.E., 4.8 PERCENT). THE RESULTS SUPPORT THE IDEA THAT A COMBINATION OF YOGA POSTURES WITH SUPINE REST (IN CM) REDUCES THE OXYGEN CONSUMPTION MORE THAN RESTING SUPINE ALONE DOES.	2006	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
20 2001  41 STRESS, INFLAMMATION, AND YOGA PRACTICE. OBJECTIVE: TO ADDRESS THE MECHANISMS UNDERLYING HATHA YOGA'S POTENTIAL STRESS-REDUCTION BENEFITS, WE COMPARED INFLAMMATORY AND ENDOCRINE RESPONSES OF NOVICE AND EXPERT YOGA PRACTITIONERS BEFORE, DURING, AND AFTER A RESTORATIVE HATHA YOGA SESSION, AS WELL AS IN TWO CONTROL CONDITIONS. STRESSORS BEFORE EACH OF THE THREE CONDITIONS PROVIDED DATA ON THE EXTENT TO WHICH YOGA SPEEDED AN INDIVIDUAL'S PHYSIOLOGICAL RECOVERY. METHODS: A TOTAL OF 50 HEALTHY WOMEN (MEAN AGE, 41.32 YEARS; RANGE, 30-65 YEARS), 25 NOVICES AND 25 EXPERTS, WERE EXPOSED TO EACH OF THE CONDITIONS (YOGA, MOVEMENT CONTROL, AND PASSIVE-VIDEO CONTROL) DURING THREE SEPARATE VISITS. RESULTS: THE YOGA SESSION BOOSTED PARTICIPANTS' POSITIVE AFFECT COMPARED WITH THE CONTROL CONDITIONS, BUT NO OVERALL DIFFERENCES IN INFLAMMATORY OR ENDOCRINE RESPONSES WERE UNIQUE TO THE YOGA SESSION. IMPORTANTLY, EVEN THOUGH NOVICES AND EXPERTS DID NOT DIFFER ON KEY DIMENSIONS, INCLUDING AGE, ABDOMINAL ADIPOSITY, AND CARDIORESPIRATORY FITNESS, NOVICES' SERUM INTERLEUKIN (IL)-6 LEVELS WERE 41% HIGHER THAN THOSE OF EXPERTS ACROSS SESSIONS, AND THE ODDS OF A NOVICE HAVING DETECTABLE C-REACTIVE PROTEIN (CRP) WERE 4.75 TIMES AS HIGH AS THAT OF AN EXPERT. DIFFERENCES IN STRESS RESPONSES BETWEEN EXPERTS AND NOVICES PROVIDED ONE PLAUSIBLE MECHANISM FOR THEIR DIVERGENT SERUM IL-6 DATA; EXPERTS PRODUCED LESS LIPOPOLYSACCHARIDE-STIMULATED IL-6 IN RESPONSE TO THE STRESSOR THAN NOVICES, AND IL-6 PROMOTES CRP PRODUCTION. CONCLUSION: THE ABILITY TO MINIMIZE INFLAMMATORY RESPONSES TO STRESSFUL ENCOUNTERS INFLUENCES THE BURDEN THAT STRESSORS PLACE ON AN INDIVIDUAL. IF YOGA DAMPENS OR LIMITS STRESS-RELATED CHANGES, THEN REGULAR PRACTICE COULD HAVE SUBSTANTIAL HEALTH BENEFITS.	2010
