1 1148 116 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
2  642  47 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	
                                                                                                                                                                                                                                             
3  404  25 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 1693  32 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
5 1246  26 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
6 1316  24 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
7 2085  30 THE EFFECT OF LONG TERM COMBINED YOGA PRACTICE ON THE BASAL METABOLIC RATE OF HEALTHY ADULTS. BACKGROUND: DIFFERENT PROCEDURES PRACTICED IN YOGA HAVE STIMULATORY OR INHIBITORY EFFECTS ON THE BASAL METABOLIC RATE WHEN STUDIED ACUTELY. IN DAILY LIFE HOWEVER, THESE PROCEDURES ARE USUALLY PRACTICED IN COMBINATION. THE PURPOSE OF THE PRESENT STUDY WAS TO INVESTIGATE THE NET CHANGE IN THE BASAL METABOLIC RATE (BMR) OF INDIVIDUALS ACTIVELY ENGAGING IN A COMBINATION OF YOGA PRACTICES (ASANA OR YOGIC POSTURES, MEDITATION AND PRANAYAMA OR BREATHING EXERCISES) FOR A MINIMUM PERIOD OF SIX MONTHS, AT A RESIDENTIAL YOGA EDUCATION AND RESEARCH CENTER AT BANGALORE. METHODS: THE MEASURED BMR OF INDIVIDUALS PRACTICING YOGA THROUGH A COMBINATION OF PRACTICES WAS COMPARED WITH THAT OF CONTROL SUBJECTS WHO DID NOT PRACTICE YOGA BUT LED SIMILAR LIFESTYLES. RESULTS: THE BMR OF THE YOGA PRACTITIONERS WAS SIGNIFICANTLY LOWER THAN THAT OF THE NON-YOGA GROUP, AND WAS LOWER BY ABOUT 13 % WHEN ADJUSTED FOR BODY WEIGHT (P < 0.001). THIS DIFFERENCE PERSISTED WHEN THE GROUPS WERE STRATIFIED BY GENDER; HOWEVER, THE DIFFERENCE IN BMR ADJUSTED FOR BODY WEIGHT WAS GREATER IN WOMEN THAN MEN (ABOUT 8 AND 18% RESPECTIVELY). IN ADDITION, THE MEAN BMR OF THE YOGA GROUP WAS SIGNIFICANTLY LOWER THAN THEIR PREDICTED VALUES, WHILE THE MEAN BMR OF NON-YOGA GROUP WAS COMPARABLE WITH THEIR PREDICTED VALUES DERIVED FROM 1985 WHO/FAO/UNU PREDICTIVE EQUATIONS. CONCLUSION: THIS STUDY SHOWS THAT THERE IS A SIGNIFICANTLY REDUCED BMR, PROBABLY LINKED TO REDUCED AROUSAL, WITH THE LONG TERM PRACTICE OF YOGA USING A COMBINATION OF STIMULATORY AND INHIBITORY YOGIC PRACTICES.	2006	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
8  967  21 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
9  295  23 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	
                                                                                                                                                                                                                                                                                                                                      
10 2751  33 YOGA PRACTICE IS ASSOCIATED WITH ATTENUATED WEIGHT GAIN IN HEALTHY, MIDDLE-AGED MEN AND WOMEN. BACKGROUND: YOGA IS PROMOTED OR WEIGHT MAINTENANCE, BUT THERE IS LITTLE EVIDENCE OF ITS EFFICACY. OBJECTIVE: TO EXAMINE WHETHER YOGA PRACTICE IS ASSOCIATED WITH LOWER MEAN 10-YEAR WEIGHT GAIN AFTER AGE 45. PARTICIPANTS: PARTICIPANTS INCLUDED 15,550 ADULTS, AGED 53 TO 57 YEARS, RECRUITED TO THE VITAMIN AND LIFESTYLE (VITAL) COHORT STUDY BETWEEN 2000 AND 2002. MEASUREMENTS: PHYSICAL ACTIVITY (INCLUDING YOGA) DURING THE PAST 10 YEARS, DIET, HEIGHT, AND WEIGHT AT RECRUITMENT AND AT AGES 30 AND 45. ALL MEASURES WERE BASED ON SELF-REPORTING, AND PAST WEIGHT WAS RETROSPECTIVELY ASCERTAINED. METHODS: MULTIPLE REGRESSION ANALYSES WERE USED TO EXAMINED COVARIATE-ADJUSTED ASSOCIATIONS BETWEEN YOGA PRACTICE AND WEIGHT CHANGE FROM AGE 45 TO RECRUITMENT, AND POLYCHOTOMOUS LOGISTIC REGRESSION WAS USED TO EXAMINE ASSOCIATIONS OF YOGA PRACTICE WITH THE RELATIVE ODDS OF WEIGHT MAINTENANCE (WITHIN 5%) AND WEIGHT LOSS (> 5%) COMPARED TO WEIGHT GAIN. RESULTS: YOGA PRACTICE FOR FOUR OR MORE YEARS WAS ASSOCIATED WITH A 3.1-LB LOWER WEIGHT GAIN AMONG NORMAL WEIGHT (BMI < 25) PARTICIPANTS [9.5 LBS VERSUS 12.6 IBS] AND AN 18.5-LB LOWER WEIGHT GAIN AMONG OVERWEIGHT PARTICIPANTS [-5.0 LBS VERSUS 13.5 IBS] (BOTH P FOR TREND <.001). AMONG OVERWEIGHT INDIVIDUALS, 4+ YEARS OF YOGA PRACTICE WAS ASSOCIATED WITH A RELATIVE ODDS OF 1.85 (95% CONFIDENCE INTERVAL [CI] 0.63-5.42) FOR WEIGHT MAINTENANCE (WITHIN 5%) AND 3.88 (95% CL 1.30-9.88) FOR WEIGHT LOSS (> 5%) COMPARED TO WEIGHT GAIN (P FOR TREND .026 AND .003, RESPECTIVELY). CONCLUSIONS: REGULAR YOGA PRACTICE WAS ASSOCIATED WITH ATTENUATED WEIGHT GAIN, MOST STRONGLY AMONG INDIVIDUALS WHO WERE OVERWEIGHT. ALTHOUGH CAUSAL INFERENCE FROM THIS OBSERVATIONAL STUDY IS NOT POSSIBLE, RESULTS ARE CONSISTENT WITH THE HYPOTHESIS THAT REGULAR YOGA PRACTICE CAN BENEFIT INDIVIDUALS WHO WISH TO MAINTAIN OR LOSE WEIGHT.	2005	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
11 1095  19 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
12 2258  36 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	

13  436  23 CARDIORESPIRATORY AND METABOLIC CHANGES DURING YOGA SESSIONS: THE EFFECTS OF RESPIRATORY EXERCISES AND MEDITATION PRACTICES. THE NOVELTY OF THIS STUDY WAS TO INVESTIGATE THE CHANGES IN CARDIORESPIRATORY AND METABOLIC INTENSITY BROUGHT ABOUT BY THE PRACTICE OF PRANAYAMAS (BREATHING EXERCISES OF YOGA) AND MEDITATION DURING THE SAME HATHA-YOGA SESSION. THE TECHNIQUE APPLIED WAS THE ONE ADVOCATED BY THE HATHA-YOGA SYSTEM. NINE YOGA INSTRUCTORS-FIVE FEMALES AND FOUR MALES, MEAN AGE OF 44+/-11, 6, WERE SUBJECTED TO ANALYSIS OF THE GASES EXPIRED DURING THREE DISTINCT PERIODS OF 30 MIN: REST, RESPIRATORY EXERCISES AND MEDITATIVE PRACTICE. A METABOLIC OPEN CIRCUIT COMPUTERIZED SYSTEM WAS APPLIED (VO2000, MEDGRAPHICS-USA). THE OXYGEN UPTAKE (VO(2)) AND THE CARBON DIOXIDE OUTPUT (VCO(2)) WERE STATISTICALLY DIFFERENT (P <OR= 0.05) DURING MEDITATION AND PRANAYAMA PRACTICES WHEN COMPARED WITH REST. THE HEART RATE ALSO SUFFERED RELEVANT REDUCTIONS WHEN RESULTS AT REST WERE COMPARED WITH THOSE DURING MEDITATION. A SMALLER PROPORTION OF LIPIDS WAS METABOLIZED DURING MEDITATION PRACTICE COMPARED WITH REST. THE RESULTS SUGGEST THAT THE MEDITATION USED IN THIS STUDY REDUCES THE METABOLIC RATE WHEREAS THE SPECIFIC PRANAYAMA TECHNIQUE IN THIS STUDY INCREASES IT WHEN COMPARED WITH THE REST STATE.	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
14 1301  22 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
15 2823  26 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 1988  26 SPECTRAL PARAMETERS OF HRV IN YOGA PRACTITIONERS, ATHLETES AND SEDENTARY MALES. PHYSICAL INACTIVITY IS AN IMPORTANT RISK FACTOR FOR CARDIOVASCULAR MORTALITY AND MORBIDITY. EXERCISE IS CONSIDERED AN ACCEPTABLE METHOD FOR IMPROVING AND MAINTAINING PHYSICAL AND EMOTIONAL HEALTH. ALTHOUGH YOGA IS HISTORICALLY A SPIRITUAL DISCIPLINE, A GROWING BODY OF EVIDENCE SUPPORTS THE BELIEF THAT YOGA BENEFITS PHYSICAL AND MENTAL HEALTH. THE OBJECTIVE OF THIS STUDY WAS TO EVALUATE HEART RATE VARIABILITY WHICH REFLECTS AUTONOMIC CONTROL OF HEART AMONG YOGA PRACTITIONERS, ATHLETES AND INDIVIDUALS WITH SEDENTARY LIFESTYLE. THE STUDY WAS CARRIED OUT IN THE DEPARTMENTS OF PHYSIOLOGY AT MAMC AGROHA, HISAR AND PT. BD SHARMA PGIMS ROHTAK, HARYANA. THE STUDY GROUP COMPRISED OF 1200 HEALTHY MALE VOLUNTEERS OF 16 TO 55 YEARS OF AGE. THE STUDY GROUP WAS DIVIDED INTO FOUR AGE GROUPS: GROUP A OF AGE 16 TO 25 YEARS; GROUP B OF AGE 26 TO 35 YEARS; GROUP C OF AGE 36 TO 45 YEARS AND GROUP D OF AGE 46 TO 55 YEARS. ALL AGE GROUPS WERE FURTHER DIVIDED INTO THREE CATEGORIES I.E ATHLETE (RUNNER), YOGA (YOGA PRACTITIONERS) AND SEDENTARY IN WHICH INDIVIDUALS WITH SEDENTARY LIFE STYLE WERE INCLUDED. THE BASAL RECORDING OF ECG IN LEAD II WAS DONE FOR 5 MINUTES. THE POLYRITE-D ECG DATA WAS USED FOR ANALYSIS OF HEART RATE VARIABILITY BY FREQUENCY DOMAIN METHOD. TWO SPECTRAL COMPONENTS WERE RECORDED NAMELY HIGH FREQUENCY (HF) COMPONENT (0.15-0.4 HZ), AN INDICATOR OF VAGAL EFFERENT ACTIVITY AND LOW FREQUENCY (LF) COMPONENT (0.04-.15 HZ), REPLICATOR OF COMPOSITE SYMPATHO-VAGAL INTERPLAY. HF COMPONENT IN NORMALIZED UNIT WAS FOUND SIGNIFICANTLY HIGH IN AGE GROUP B AND C IN YOGA PRACTITIONERS AND ATHLETES AS COMPARED TO SEDENTARY INDIVIDUALS AND IN AGE GROUP D SIGNIFICANTLY HIGH IN YOGA PRACTITIONERS AS COMPARED TO ATHLETES AND SEDENTARY INDIVIDUALS. SIGNIFICANTLY DECREASED LF/HF RATIO WAS FOUND IN AGE GROUP B AND C IN YOGA AND ATHLETE SUBJECTS AS COMPARED TO SEDENTARY INDIVIDUALS AND IN AGE GROUP D IN YOGA PRACTITIONERS AS COMPARED TO ATHLETES AND SEDENTARY INDIVIDUALS. THIS INDICATES THAT PARASYMPATHETIC ACTIVITY IS SUBSTANTIALLY GREATER IN YOGA PRACTITIONERS.	2015	
                                                                                                                                                                                                                                                                                                                                                      
17  356  34 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                    
18  277  19 ADDITIONAL PRACTICE OF YOGA BREATHING WITH INTERMITTENT BREATH HOLDING ENHANCES PSYCHOLOGICAL FUNCTIONS IN YOGA PRACTITIONERS: A RANDOMIZED CONTROLLED TRIAL. BACKGROUND AND OBJECTIVE: THE PRACTICE OF YOGA IS ASSOCIATED WITH ENHANCED PSYCHOLOGICAL WELLBEING. THE CURRENT STUDY ASSESSED THE CORRELATION BETWEEN THE DURATION OF YOGA PRACTICE WITH STATE MINDFULNESS, MIND-WANDERING AND STATE ANXIETY. ALSO, WE EXAMINED IF AN ADDITIONAL 20 MIN OF YOGA BREATHING WITH INTERMITTENT BREATH HOLDING (EXPERIMENTAL GROUP) FOR 8 WEEKS WOULD AFFECT THESE PSYCHOLOGICAL VARIABLES MORE THAN REGULAR YOGA PRACTICE (CONTROL GROUP) ALONE. METHODS: ONE HUNDRED SIXTEEN SUBJECTS WERE RANDOMLY ASSIGNED TO EXPERIMENTAL (N = 60) AND CONTROL (N = 56) GROUPS. STATE MINDFULNESS ATTENTION AWARENESS SCALE (SMAAS), MIND-WANDERING QUESTIONNAIRE (MWQ) AND STATE ANXIETY INVENTORY WERE ADMINISTERED AT BASELINE AND AT THE END OF 8 WEEKS. RESULTS: BASELINE ASSESSMENT REVEALED A POSITIVE CORRELATION BETWEEN DURATION OF YOGA PRACTICE WITH SMAAS SCORES AND NEGATIVE CORRELATION WITH MWQ AND STATE ANXIETY SCORES. AT THE END OF 8 WEEKS, BOTH GROUPS DEMONSTRATED ENHANCED PSYCHOLOGICAL FUNCTIONS, BUT THE EXPERIMENTAL GROUP RECEIVING ADDITIONAL YOGA BREATHING PERFORMED BETTER THAN THE GROUP PRACTICING YOGA ALONE. CONCLUSION: AN ADDITIONAL PRACTICE OF YOGA BREATHING WITH INTERMITTENT BREATH HOLDING WAS FOUND TO ENHANCE THE PSYCHOLOGICAL FUNCTIONS IN YOUNG ADULT YOGA PRACTITIONERS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
19  471  25 CHARACTERISTICS OF YOGA PRACTITIONERS, MOTIVATORS, AND YOGA TECHNIQUES OF CHOICE: A CROSS-SECTIONAL STUDY. BACKGROUND: THE CHARACTERISTICS OF YOGA PRACTITIONERS AND FACTORS MOTIVATING PEOPLE TO PRACTICE YOGA HAVE BEEN STUDIED IN THE US AND IN AUSTRALIA. THIS STUDY AIMED TO DETERMINE THE CHARACTERISTICS OF YOGA USERS IN INDIA, THE FACTORS THAT MOTIVATE THEM TO PRACTICE YOGA, AND THE YOGA TECHNIQUES OF CHOICE. MATERIALS AND METHODS: THE STUDY WAS A ONE-TIME, CROSS-SECTIONAL SURVEY BASED ON CONVENIENCE SAMPLING. INCLUSION CRITERIA WERE (A) A MINIMUM OF 1 WEEK EXPERIENCE OF YOGA AND (B) AT LEAST 10 YEARS OF AGE. 14,250 PEOPLE RECEIVED THE SURVEY. AFTER EXCLUDING THOSE WHO DID NOT MEET THE INCLUSION CRITERIA OR FILLED IN THE SURVEY INCOMPLETELY OR INCORRECTLY, 5,157 RESPONDENTS WERE INCLUDED IN THE STUDY. RESULTS: OUT OF 5,157 RESPONDENTS, THERE WERE MORE MALES (67.3%), AGED BETWEEN 21 AND 44 YEARS (33.7% OF THE SAMPLE SURVEYED), EDUCATED UP TO HIGH SCHOOL (62.5%), STUDENTS (39.3%), AND THOSE WHO HAD BETWEEN 1 AND 12 MONTHS OF EXPERIENCE IN YOGA (54.4%). THE FIRST MOST COMMON REASON TO PRACTICE YOGA FOR ALL RESPONDENTS WAS PHYSICAL FITNESS. THREE OF THE REMAINING REASONS TO PRACTICE YOGA DIFFERED SIGNIFICANTLY WITH AGE: (I) YOGA FOR DISEASE MANAGEMENT (CHI(2) = 17.62, P < 0.005), (II) YOGA AS A HOBBY (CHI(2) = 10.87, P < 0.05), AND (III) YOGA BASED ON THE GURU'S (TEACHER'S) INSTRUCTIONS (CHI(2) = 20.05, P < 0.001). THE YOGA TECHNIQUE OF CHOICE [I.E., (I) ASANAS (CHI(2) = 23.17, P < 0.001), (II) PRANAYAMA (CHI(2) = 19.87, P < 0.001), OR (III) MEDITATION (CHI(2) = 9.64, P < 0.05)] DIFFERED SIGNIFICANTLY ACROSS AGE GROUPS. CONCLUSION: IN INDIA, A YOGA PRACTITIONER WAS MORE LIKELY TO BE MALE, BETWEEN 21 AND 44 YEARS OF AGE, HIGH SCHOOL EDUCATED, AND A STUDENT. THE REASONS TO PRACTICE YOGA AND THE YOGA TECHNIQUE OF CHOICE DIFFERED SIGNIFICANTLY WITH AGE.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
20  417  33 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
