1 1693 122 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
2 1148  32 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
3  404  30 BIKRAM YOGA TRAINING AND PHYSICAL FITNESS IN HEALTHY YOUNG ADULTS. THERE HAS BEEN RELATIVELY LITTLE LONGITUDINAL CONTROLLED INVESTIGATION OF THE EFFECTS OF YOGA ON GENERAL PHYSICAL FITNESS, DESPITE THE WIDESPREAD PARTICIPATION IN THIS FORM OF EXERCISE. THE PURPOSE OF THIS EXPLORATORY STUDY WAS TO EXAMINE THE EFFECT OF SHORT-TERM BIKRAM YOGA TRAINING ON GENERAL PHYSICAL FITNESS. YOUNG HEALTHY ADULTS WERE RANDOMIZED TO YOGA TRAINING (N = 10, 29 +/- 6 YEARS, 24 SESSIONS IN 8 WEEKS) OR A CONTROL GROUP (N = 11, 26 +/- 7 YEARS). EACH YOGA TRAINING SESSION CONSISTED OF 90-MINUTE STANDARDIZED SUPERVISED POSTURES PERFORMED IN A HEATED AND HUMIDIFIED STUDIO. ISOMETRIC DEADLIFT STRENGTH, HANDGRIP STRENGTH, LOWER BACK/HAMSTRING AND SHOULDER FLEXIBILITY, RESTING HEART RATE AND BLOOD PRESSURE, MAXIMAL OXYGEN CONSUMPTION (TREADMILL), AND LEAN AND FAT MASS (DUAL-ENERGY X-RAY ABSORPTIOMETRY) WERE MEASURED BEFORE AND AFTER TRAINING. YOGA SUBJECTS EXHIBITED INCREASED DEADLIFT STRENGTH, SUBSTANTIALLY INCREASED LOWER BACK/HAMSTRING FLEXIBILITY, INCREASED SHOULDER FLEXIBILITY, AND MODESTLY DECREASED BODY FAT COMPARED WITH CONTROL GROUP. THERE WERE NO CHANGES IN HANDGRIP STRENGTH, CARDIOVASCULAR MEASURES, OR MAXIMAL AEROBIC FITNESS. IN SUMMARY, THIS SHORT-TERM YOGA TRAINING PROTOCOL PRODUCED BENEFICIAL CHANGES IN MUSCULOSKELETAL FITNESS THAT WERE SPECIFIC TO THE TRAINING STIMULUS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
4  642  44 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	
                                                                                                                                                                                                                                             
5  967  23 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  295  27 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	
                                                                                                                                                                                                                                                                                                                                      
7  417  38 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	
                                                                                                                                                                                                                                                                                                                                                                                                                               
8 2131  26 THE EFFECTS OF A 6-MONTH MODERATE-INTENSITY HATHA YOGA-BASED TRAINING PROGRAM ON HEALTH-RELATED FITNESS IN MIDDLE-AGED SEDENTARY WOMEN: A RANDOMIZED CONTROLLED STUDY. BACKGROUND: THERE IS PAUCITY OF DATA EXAMINING THE EFFECTIVENESS OF LONG-TERM HATHA YOGA-BASED (HY) PROGRAMS FOCUSED ON THE HEALTH-RELATED FITNESS (H-RF) OF ASYMPTOMATIC, SEDENTARY WOMEN. THE PURPOSE OF THIS STUDY WAS TO EXAMINE THE EFFECTS OF A 6-MONTH HY-BASED TRAINING PROGRAM ON H-RF COMPONENTS IN SEDENTARY MIDDLE-AGED WOMEN. METHODS: EIGHTY SEDENTARY WOMEN WERE RANDOMLY ASSIGNED INTO EITHER THE HY GROUP (HYG) (N.=42) OR THE CONTROL GROUP (CG) (N.=38). THE 6-MONTH HYG PROGRAM INVOLVED A PROGRESSIVE SERIES OF VINYASA FLOW POSES PERFORMED 3 TIMES/WEEK FOR 60 MINUTES (40 MINUTES WITHIN THE EXERCISE ZONE OF 60-75% HR<INF>MAX</INF>). THE CG PARTICIPANTS DID NOT UNDERGO ANY PHYSICAL TRAINING OR EDUCATION. HEALTH-RELATED FITNESS PARAMETERS INCLUDED MEASURES OF PRE- AND POST-TRAINING: BODY COMPOSITION, MUSCULAR STRENGTH AND MAXIMAL VOLUNTARY ISOMETRIC TORQUES OF ELBOW FLEXORS AND KNEE EXTENSORS, CARDIO-RESPIRATORY FITNESS, LOWER BACK AND HAMSTRING FLEXIBILITY AND A STATIC-DYNAMIC BALANCE. RESULTS: TWO-WAY MIXED DESIGN ANOVA REVEALED SIGNIFICANT MAIN EFFECTS FOR ALL THE INDICATORS OF H-RF. TUKEY POST-HOC TESTS CONFIRMED THAT THE HYG DEMONSTRATED SIGNIFICANT IMPROVEMENTS IN EVERY VARIABLE TESTED. EXAMPLES OF THE BENEFITS ACHIEVED INCLUDE (ALL P<.001): AN AVERAGE LOSS OF 1.03 KG AND A 4.82% DECREASE IN BODY FAT, 14.6% AND 13.1% GAINS IN ISOMETRIC STRENGTH OF THE KNEE EXTENSORS AND ELBOW FLEXORS RESPECTIVELY, AN INCREASE IN RELATIVE VO<INF>2MAX</INF> OF 6.1% (33.12+/-5.30 TO 35.14+/-4.82 ML/KG/MIN), A 4-CM OR 10.4% INCREASE IN THEIR MSAR, AND AN AVERAGE IMPROVED BALANCE INDEX OF 5.6 MM/S. REVERSELY, THE CG SHOWED NON-SIGNIFICANT CHANGES IN H-RF VARIABLES (ALL P>0.05; PERCENT RANGE FROM -1.4% TO 1.1%). CONCLUSIONS: BY PARTICIPATING IN A MODERATE-INTENSITY 6-MONTH HY-BASED TRAINING PROGRAM, MIDDLE-AGED WOMEN CAN SIGNIFICANTLY IMPROVE THEIR HR-F STATUS. THE APPLICATION OF PROGRESSIVE TARGET HEART RATE GOALS FACILITATED GREATER THAN EXPECTED IMPROVEMENTS IN CARDIO-RESPIRATORY FITNESS AND IMPROVEMENTS IN BODY COMPOSITION.	2020	
                                                                                                                                                                                                                                                                                         
9  436  29 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
10  356  37 ASSOCIATION BETWEEN HAMSTRING FLEXIBILITY AND SPRINT SPEED AFTER 8 WEEKS OF YOGA IN MALE RUGBY PLAYERS. BACKGROUND: A YOGA-ASANA-BASED INTERVENTION HAS DEMONSTRATED ITS ABILITY TO IMPROVE FLEXIBILITY OF INDIVIDUALS, BUT HAS NOT BEEN EXPLORED IN RUGBY PLAYERS. WE HYPOTHESIZED THAT A STRUCTURED YOGA INTERVENTION MAY HAVE AN EFFECT ON FLEXIBILITY AND SPRINT PERFORMANCE IN MALE RUGBY UNION PLAYERS. METHODS: IT WAS A CONTROLLED TRIAL RESEARCH DESIGN AND PLAYERS WERE ASSIGNED USING RANDOM SAMPLING TO ONE OF THE TWO GROUPS; A YOGA GROUP (N = 16) THAT PRACTISED YOGA FOR 1 H 2 TIMES A WEEK FOR 8 WEEKS IN ADDITION TO THEIR NORMAL RUGBY TRAINING AND A CONTROL GROUP (N = 15) WITH REGULAR RUGBY TRAINING BUT NO YOGA INTERVENTION. YOGA INTERVENTION INCLUDED 32 YOGA POSTURES TO ADDRESS BOTH THE UPPER AND LOWER EXTREMITIES OF THE BODY. DATA WERE COLLECTED DURING PRESEASON AND MID-SEASON ON HAMSTRING FLEXIBILITY (SIT AND REACH TEST), AND SPRINT PERFORMANCE (MEASURED AT 5, 10, AND 30 M). RESULTS: ONE HUNDRED AND TWENTY PARTICIPANTS WERE SCREENED AND THIRTY-ONE PLAYERS VOLUNTEERED FOR THE STUDY. INTERACTIONS BETWEEN GROUPS AND DIFFERENCES BETWEEN PRE- AND POST-INTERVENTION SCORES WERE ANALYZED USING ANALYSIS OF VARIANCE USING SPSS (VERSION 24.0). SIGNIFICANCE WAS SET AT AN ALPHA LEVEL OF P = 0.05. THE YOGA GROUP SHOWED A SMALL NONSIGNIFICANT DECREASE (-1.2% +/- 21.4%, P = 0.05) IN HAMSTRING FLEXIBILITY COMPARED TO THE CONTROL GROUP WHICH DEMONSTRATED A LARGE SIGNIFICANT DECREASE (-14.8% +/- 23.7%) (MEAN % CHANGE +/- 95% CONFIDENCE INTERVAL [CI], P < 0.05). THE YOGA GROUP ALSO SHOWED MINOR NONSIGNIFICANT IMPROVEMENTS IN SPRINT TIMES -3.2% +/- 10.4%, -0.7% +/- 9.0% FOR THE 5 AND 10 M SPRINTS, RESPECTIVELY, (MEAN % CHANGE +/- 95% CI) COMPARED TO CONTROLS -0.4% +/- 10.2%, 0.4% +/- 7.9%. CONCLUSIONS: FINDINGS SUGGEST THAT COMPLETING A STRUCTURED YOGA INTERVENTION ALONGSIDE NORMAL RUGBY TRAINING DURING THE RUGBY SEASON, YOGA HELPED RUGBY PLAYERS MAINTAIN THEIR HAMSTRING FLEXIBILITY BUT DID LITTLE TO IMPROVE SPRINT PERFORMANCE DURING THE SEASON.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                    
11 1246  30 FEASIBILITY OF INTEGRATION OF YOGA IN A BEHAVIORAL WEIGHT-LOSS INTERVENTION: A RANDOMIZED TRIAL. OBJECTIVE: THIS STUDY EXAMINED THE FEASIBILITY AND COMPARISON OF TWO STYLES OF YOGA WITHIN THE CONTEXT OF A STANDARD BEHAVIORAL WEIGHT-LOSS INTERVENTION (SBWI). METHODS: FIFTY ADULTS WITH OBESITY (BMI: 31.3 +/- 3.8 KG/M(2) ) PARTICIPATED IN THIS 6-MONTH STUDY THAT INCLUDED A SBWI AND A CALORIE- AND FAT-REDUCED DIET. RANDOMIZATION WAS TO RESTORATIVE HATHA (SBWI+RES) OR VINYASA (SBWI+VIN) YOGA. YOGA WAS PRESCRIBED TO INCREASE FROM 20 TO 40 TO 60 MINUTES PER SESSION ACROSS THE INTERVENTION. WEIGHT WAS ASSESSED AT BASELINE AND 6 MONTHS. PERCEPTIONS OF YOGA WERE ASSESSED AT THE COMPLETION OF THE INTERVENTION. RESULTS: ADJUSTED WEIGHT LOSS WAS -3.4 KG (95% CI: -6.4 TO -0.5) IN SBWI+RES AND -3.8 KG (95% CI: -6.8 TO -0.9) IN SBWI+VIN (P < 0.001), WITH NO DIFFERENCE BETWEEN GROUPS. OF ALL PARTICIPANTS, 74.4% REPORTED THAT THEY WOULD CONTINUE PARTICIPATION IN YOGA AFTER THE SBWI. SESSION DURATION WAS A BARRIER AS YOGA INCREASED FROM 20 TO 40 TO 60 MINUTES PER DAY, WITH 0%, 7.5%, AND 48.8% REPORTING THIS BARRIER, RESPECTIVELY. CONCLUSIONS: AMONG ADULTS WITH OBESITY, YOGA PARTICIPATION, WITHIN THE CONTEXT OF A SBWI, APPEARS TO BE FEASIBLE, WITH WEIGHT LOSS NOT DIFFERING BY STYLE OF YOGA. PROGRESSING TO 60 MINUTES PER SESSION APPEARS TO BE A BARRIER TO ENGAGEMENT IN YOGA IN THIS POPULATION.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
12 1316  22 HEART RATE AND THERMAL RESPONSES TO POWER YOGA. BACKGROUND: AND PURPOSE: YOGA HAS GROWN IN POPULARITY AND MAY OFFER A VIABLE ALTERNATIVE FORM OF PHYSICAL ACTIVITY. THE PURPOSE OF THIS STUDY WAS TO EXAMINE HEART RATE, HYDRATION, AND THERMAL RESPONSES TO A POWER YOGA SEQUENCE. MATERIALS AND METHODS: TWENTY-SEVEN MEN AND WOMEN (N=4/23; MEAN+/-SD AGE=23.3+/-3.3 YEARS; BMI=23+/-3KGM(-2)) UNDERWENT APPROXIMATELY 45MIN OF POWER YOGA. HEART RATE AND SKIN TEMPERATURE WERE RECORDED. MASS WAS MEASURED BEFORE AND AFTER EXERCISE TO ESTIMATE FLUID LOSS. TIME SPENT IN LIGHT, MODERATE, AND VIGOROUS HEART RATE ZONES WAS CALCULATED. RESULTS: HEART RATE AND SKIN TEMPERATURE INCREASED (P<0.0001). PARTICIPANTS SPENT MORE TIME IN MODERATE AND VIGOROUS HEART RATE ZONES THAN IN LIGHT INTENSITY (P<0.0001). THERE WAS A REDUCTION IN BODY MASS (-0.28+/-0.13KG, P<0.0001). CONCLUSION: POWER YOGA MAY BE CONSIDERED MODERATE-VIGOROUS INTENSITY EXERCISE, BASED ON HEART-RATE.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
13 1095  23 EFFECTS OF YOGA PRACTICE ON MUSCULAR ENDURANCE IN YOUNG WOMEN. THE AIM OF THIS STUDY WAS TO VERIFY THE EFFECTS OF A SYSTEMATIZED YOGA PRACTICE ON MUSCULAR ENDURANCE IN YOUNG WOMEN. TWENTY SIX WOMEN (24 +/- 3.5 YEARS OLD) PARTICIPATED IN SIX WEEKS OF YOGA CLASSES, AND TWENTY ONE WOMEN (25 +/- 5.1 YEARS OLD) PARTICIPATED AS THE CONTROL GROUP. THE YOGA INTERVENTION WAS COMPOSED OF EIGHTEEN SESSIONS, THREE TIMES PER WEEK, AT 1 H PER SESSION. THE MUSCULAR ENDURANCE OF UPPER LIMBS (PUSH-UP) AND ABDOMINAL (SIT-UP) WAS ASSESSED THROUGH THE PROTOCOL SUGGESTED BY GETTMAN (1989) [1] AND GOLDING, MYERS AND SINNING (1989) [2] TO THE MAXIMUM REPETITIONS PERFORMED IN 1 MIN. TO VERIFY THE SIGNIFICANT DIFFERENCES INTRA GROUPS AND BETWEEN GROUPS A SPANOVA WAS PERFORMED, AND THE LEVEL OF SIGNIFICANCE WAS P </= 0.05. THE FINDINGS SUGGEST THAT YOGA PROVIDES IMPROVEMENT IN UPPER LIMB AND IN ABDOMINAL MUSCULAR ENDURANCE.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
14  943  25 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
15 2823  28 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
16 1147  41 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
17  821  21 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
18 1301  30 HATHA YOGA ON BODY BALANCE. BACKGROUND: A GOOD BODY BALANCE REQUIRES A PROPER FUNCTION OF VESTIBULAR, VISUAL, AND SOMATOSENSORY SYSTEMS WHICH CAN BE REACH WITH EXERCISE PRACTICE AND/OR YOGA. AIM: TO DETERMINE THE EFFECTS OF A 5-MONTH HATHA YOGA TRAINING PROGRAM ON BODY BALANCE IN YOUNG ADULTS. MATERIALS AND METHODS: THIS STUDY USED A CONTROLLED, NONRANDOMIZED DESIGN, WHERE THE EXPERIMENTAL GROUP UNDERWENT A 5-MONTH TRAINING PROGRAM AND WERE THEN COMPARED WITH THE CONTROL GROUP THAT HAD A SEDENTARY LIFESTYLE. A CONVENIENCE SAMPLE OF 34 OUT OF 40 MEN AGED 25-55 YEARS OLD (34.0 +/- 0.9) WERE DEEMED ELIGIBLE FOR THIS STUDY. THEY WERE RANDOMLY DIVIDED INTO TWO GROUPS: EXPERIMENTAL AND CONTROL GROUPS. SUBJECTS IN THE EXPERIMENTAL GROUP WERE ENGAGED IN 60 MIN SESSIONS OF HATHA YOGA THREE TIMES A WEEK FOR 5 MONTHS. WE EVALUATED POSTURAL CONTROL BY MEASURING THE LIMIT OF STABILITY AND VELOCITY OF OSCILLATION (VOS) IN THREE CONDITIONS OF THE BALANCE REHABILITATION UNIT (BRU) AND THROUGH FIELD PROCEDURES (FOUR POSITION, PLANE, FLAMINGO, HOPSCOTCH, AND DYNAMIC TEST). RESULTS: WE OBSERVED DIFFERENCES (P < 0.05) IN POSTINTERVENTION SCORES BETWEEN THE GROUPS REGARDLESS OF BRU PARAMETERS AND FIELD PROCEDURES (EXCEPT FOR FLAMINGO) EVEN AFTER ADJUSTING FOR PREINTERVENTION SCORES, SUGGESTING THAT THESE CHANGES WERE INDUCED BY HATHA YOGA TRAINING. THE PARTIAL ETA SQUARED ON BRU PARAMETERS RANGED FROM 0.78 (VOS1)-0.97 (COP2), AND FROM 0.00 (FLAMINGO)-0.94 (FOUR POSITION) FOR THE FIELD PROCEDURES. CONCLUSIONS: OUR RESULTS PROVIDE SUBSTANTIAL EVIDENCE THAT POSTURAL CONTROL IN HEALTHY YOUNG ADULTS CAN BE IMPROVED THROUGH PRACTICING HATHA YOGA.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
19 2258  40 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	

20  416  35 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
