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  268  36 ACUTE PHYSIOLOGIC EFFECTS OF PERFORMING YOGA IN THE HEAT ON ENERGY EXPENDITURE, RANGE OF MOTION, AND INFLAMMATORY BIOMARKERS. PERFORMING YOGA IN A HEATED ENVIRONMENT (HY) IS A POPULAR EXERCISE MODE PURPORTED TO IMPROVE RANGE OF MOTION (ROM), BODY COMPOSITION, AND AEROBIC FITNESS. THE PURPOSE OF THIS INVESTIGATION WAS TO COMPARE A SESSION OF HY TO ROOM TEMPERATURE YOGA (RTY) WITH REGARDS TO ROM, OXYGEN CONSUMPTION, CALORIC EXPENDITURE, AND BIOMARKERS OF ACUTE STRESS AND INFLAMMATION. SIXTEEN EXPERIENCED YOGA PRACTITIONERS (F14, M2; 40 +/- 11YR; 22.6 +/- 1.8 KG/M(2)) COMPLETED A 1-HOUR STANDARDIZED BIKRAM SEQUENCE IN HY (105 DEGREES F, 40 DEGREES C) AND RTY (74 DEGREES F, 23.3 DEGREES C) CONDITIONS (ORDER OF CONDITIONS RANDOMIZED, HUMIDITY STANDARDIZED AT 40%). INTRA-EXERCISE METABOLIC GAS EXCHANGE AND HEART RATE (HR) WAS MONITORED USING A METABOLIC CART. ROM MEASURES WERE TAKEN PRE AND POST-EXERCISE AT THE ELBOW, SHOULDER, HIP, AND KNEE. CYTOKINES INTERLEUKIN 6,10 (IL-6, IL-10) AND TUMOR-NECROSIS-FACTOR ALPHA (TNF-ALPHA) WERE ANALYZED FROM BLOOD SAMPLES COLLECTED PRE- AND 30-MINUTES POST-EXERCISE. INTRA-EXERCISE METABOLIC GAS EXCHANGE AND HEART RATE (HR) WAS MONITORED USING A METABOLIC CART. BOTH BOUTS ELICITED SIMILAR ACUTE CHANGES IN ROM ALTHOUGH HY ELICITED A GREATER INCREASE IN HIP ABDUCTION (RTYDELTA DEGREES = 2.3 +/- 1.3|HYDELTA DEGREES = 6.6 +/- 1.5; P < 0.05). MEAN VO2, PEAK VO2, %VO2MAX, HR, AND KCAL EXPENDITURE DID NOT DIFFER BETWEEN CONDITIONS. RER WAS LOWER DURING THE HY (RTY = 0.95 +/- 0.02| HY = 0.89 +/- 0.02; P < 0.05) WITH A CONCOMITANT ELEVATION IN FAT OXIDATION (RTY = 0.05 +/- 0.01|HY = 0.09 +/- 0.01, G.MIN(-1); P < 0.05) AND DECREASE IN CARBOHYDRATE OXIDATION (RTY = 0.51 +/- 0.04|HY = 0.44 +/- 0.03, G.MIN(-1); P < 0.05). SERUM IL-6 WAS INCREASED (15.5 +/- 8.0-FOLD) FOLLOWING HY ONLY (P < 0.05). HY DOES NOT SIGNIFICANTLY ELEVATE AEROBIC ENERGY COST COMPARED TO RTY BUT MAY ACUTELY INCREASE FAT SUBSTRATE UTILIZATION AND HIP ROM. FUTURE STUDIES REMAIN NEEDED TO ESTABLISH DOSE-RESPONSE RELATIONSHIPS FOR INCLUDING HY OR RTY INTO WELL-ROUNDED FITNESS PROGRAMS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
3 1676  31 OBJECTIVE AND SUBJECTIVE MEASURES OF EXERCISE INTENSITY DURING THERMO-NEUTRAL AND HOT YOGA. WHILE HOT YOGA HAS GAINED ENORMOUS POPULARITY IN RECENT YEARS, OWING IN PART TO INCREASED ENVIRONMENTAL CHALLENGE ASSOCIATED WITH EXERCISE IN THE HEAT, IT IS NOT CLEAR WHETHER HOT YOGA IS MORE VIGOROUS THAN THERMO-NEUTRAL YOGA. THEREFORE, THE AIM OF THIS STUDY WAS TO DETERMINE OBJECTIVE AND SUBJECTIVE MEASURES OF EXERCISE INTENSITY DURING CONSTANT INTENSITY YOGA IN A HOT AND THERMO-NEUTRAL ENVIRONMENT. USING A RANDOMIZED, CROSSOVER DESIGN, 14 PARTICIPANTS COMPLETED 2 IDENTICAL APPROXIMATELY 20-MIN YOGA SESSIONS IN A HOT (35.3 +/- 0.8 DEGREES C; HUMIDITY: 20.5% +/- 1.4%) AND THERMO-NEUTRAL (22.1 +/- 0.2 DEGREES C; HUMIDITY: 27.8% +/- 1.6%) ENVIRONMENT. OXYGEN CONSUMPTION AND HEART RATE (HR) WERE RECORDED AS OBJECTIVE MEASURES (PERCENTAGE OF MAXIMAL OXYGEN CONSUMPTION AND PERCENTAGE OF MAXIMAL HR (%HRMAX)) AND RATING OF PERCEIVED EXERTION (RPE) WAS RECORDED AS A SUBJECTIVE MEASURE OF EXERCISE INTENSITY. THERE WAS NO DIFFERENCE IN EXERCISE INTENSITY BASED ON PERCENTAGE OF MAXIMAL OXYGEN CONSUMPTION DURING HOT VERSUS THERMO-NEUTRAL YOGA (30.9% +/- 2.3% VS. 30.5% +/- 1.8%, P = 0.68). HOWEVER, EXERCISE INTENSITY WAS SIGNIFICANTLY HIGHER DURING HOT VERSUS THERMO-NEUTRAL YOGA BASED ON %HRMAX (67.0% +/- 2.3% VS. 60.8% +/- 1.9%, P = 0.01) AND RPE (12 +/- 1 VS. 11 +/- 1, P = 0.04). ACCORDING TO ESTABLISHED EXERCISE INTENSITIES, HOT YOGA WAS CLASSIFIED AS LIGHT-INTENSITY EXERCISE BASED ON PERCENTAGE OF MAXIMAL OXYGEN CONSUMPTION BUT MODERATE-INTENSITY EXERCISE BASED ON %HRMAX AND RPE WHILE THERMO-NEUTRAL YOGA WAS CLASSIFIED AS LIGHT-INTENSITY EXERCISE BASED ON PERCENTAGE OF MAXIMAL OXYGEN UPTAKE, %HRMAX, AND RPE. DESPITE THE ADDED HEMODYNAMIC STRESS AND PERCEPTION THAT YOGA IS MORE STRENUOUS IN A HOT ENVIRONMENT, WE OBSERVED SIMILAR OXYGEN CONSUMPTION DURING HOT VERSUS THERMO-NEUTRAL YOGA, CLASSIFYING BOTH EXERCISE MODALITIES AS LIGHT-INTENSITY EXERCISE.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
4 1017  34 EFFECTS OF SINGLE BOUTS OF WALKING EXERCISE AND YOGA ON ACUTE MOOD SYMPTOMS IN PEOPLE WITH MULTIPLE SCLEROSIS. BACKGROUND: LITTLE IS KNOWN ABOUT THE ACUTE OR IMMEDIATE EFFECTS OF WALKING EXERCISE AND YOGA ON MOOD IN PEOPLE WITH MULTIPLE SCLEROSIS (MS). SUCH AN EXAMINATION IS IMPORTANT FOR IDENTIFYING AN EXERCISE MODALITY FOR INCLUSION IN EXERCISE-TRAINING INTERVENTIONS THAT YIELDS MOOD BENEFITS IN MS. WE EXAMINED THE EFFECTS OF SINGLE BOUTS OF TREADMILL WALKING AND YOGA COMPARED WITH A QUIET, SEATED-REST CONTROL CONDITION ON ACUTE MOOD SYMPTOMS IN MS. METHODS: TWENTY-FOUR PARTICIPANTS WITH MS COMPLETED 20 MINUTES OF TREADMILL WALKING, YOGA, OR QUIET REST IN A RANDOMIZED, COUNTERBALANCED ORDER WITH 1 WEEK BETWEEN SESSIONS. PARTICIPANTS COMPLETED THE PROFILE OF MOOD STATES QUESTIONNAIRE BEFORE AND IMMEDIATELY AFTER EACH CONDITION. TOTAL MOOD DISTURBANCE (TMD) AND THE SIX SUBSCALES OF THE PROFILE OF MOOD STATES WERE ANALYZED USING REPEATED-MEASURES ANALYSIS OF VARIANCE AND PAIRED-SAMPLES T TESTS. RESULTS: THERE WAS A SIGNIFICANT CONDITION X TIME INTERACTION ON TMD SCORES (ETAP (2) = 0.13). WALKING AND YOGA CONDITIONS YIELDED COMPARABLE REDUCTIONS IN TMD SCORES. THERE WAS A SIGNIFICANT CONDITION X TIME INTERACTION ON VIGOR (ETAP (2) = 0.23) WHEREBY WALKING BUT NOT YOGA YIELDED AN IMPROVEMENT IN VIGOR. THERE WAS A SIGNIFICANT MAIN EFFECT OF TIME ON ANGER, CONFUSION, DEPRESSION, AND TENSION (P < .05) BUT NOT ON FATIGUE. CONCLUSIONS: WALKING AND YOGA YIELDED SIMILAR IMPROVEMENTS IN OVERALL ACUTE MOOD SYMPTOMS, AND WALKING IMPROVED FEELINGS OF VIGOR. THESE EFFECTS SHOULD BE FURTHER INVESTIGATED IN LONG-TERM EXERCISE-TRAINING STUDIES.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
5 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
6  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	
                                                                                                                                                                                                                                                                                                                                 
7 1297  21 HATHA YOGA AND EXECUTIVE FUNCTION: A SYSTEMATIC REVIEW. INTRODUCTION: RECENT REVIEWS HAVE DOCUMENTED THE BENEFICIAL EFFECTS OF SEATED MEDITATION ON EXECUTIVE FUNCTION (EF). HOWEVER, THERE HAS YET TO BE A COMPREHENSIVE REVIEW ON THE EFFECTS OF HATHA YOGA, A MOVING MEDITATION, ON EF. OBJECTIVE: TO EXAMINE THE EMPIRICAL LITERATURE ON THE EFFECTS OF HATHA YOGA ON EF. METHODS: MEDLINE, SCOPUS, AND PSYCINFO DATABASES WERE SEARCHED FOR EXPERIMENTAL STUDIES (BETWEEN- OR WITHIN-SUBJECT DESIGNS) TESTING THE EFFECTS OF HATHA YOGA (ACUTE BOUTS, SHORT-TERM INTERVENTIONS, LONGER-TERM INTERVENTIONS) ON EF. RESULTS: A TOTAL OF 11 PUBLISHED STUDIES MET ELIGIBILITY CRITERIA: THREE STUDIES INVOLVED HEALTHY ADULTS, 2 STUDIES INVOLVED HEALTHY OLDER ADULTS (N = 2), 1 STUDY INVOLVED CHILDREN AND ADOLESCENTS, AND 5 STUDIES INVOLVED MEDICAL (N = 4) OR FORENSIC (N = 1) POPULATIONS. IN HEALTHY ADULTS, 2 OF 3 STUDIES SUGGESTED THAT ACUTE BOUTS OF HATHA YOGA IMPROVED EF; HOWEVER, 1 STUDY USING A SHORT-TERM INTERVENTION FOUND NO IMPROVEMENTS IN EF. AMONG HEALTHY OLDER ADULTS, 1 STUDY PROVIDED EVIDENCE THAT HATHA YOGA IMPROVES EF. IN CHILD/ADOLESCENT SAMPLES, 1 STUDY SUPPORTED THE CONTENTION THAT HATHA YOGA IMPROVES EF AFTER SHORT-TERM INTERVENTIONS. AMONG MEDICAL POPULATIONS, EF IMPROVED IN PATIENTS WITH TYPE 2 DIABETES MELLITUS AND IN 1 OF 3 STUDIES INVOLVING PATIENTS WITH MULTIPLE SCLEROSIS. THE SOLE STUDY INVOLVING IMPULSIVE PRISONERS SHOWED POSITIVE EFFECTS ON EF WITH A SHORT-TERM INTERVENTION. CONCLUSION: HATHA YOGA SHOWS PROMISE OF BENEFIT FOR EF IN HEALTHY ADULTS, CHILDREN, ADOLESCENTS, HEALTHY OLDER ADULTS, IMPULSIVE PRISONERS, AND MEDICAL POPULATIONS (WITH THE EXCEPTION OF MULTIPLE SCLEROSIS). HOWEVER, MORE GOOD-QUALITY STUDIES THAT EVALUATE THE EFFICACY OF HATHA YOGA'S EFFECTS ON EF ARE ESSENTIAL TO BUILD ON THIS EVIDENCE BASE.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
8  630  26 DIFFERENCES IN ENERGY EXPENDITURE DURING HIGH-SPEED VERSUS STANDARD-SPEED YOGA: A RANDOMIZED SEQUENCE CROSSOVER TRIAL. OBJECTIVES: TO COMPARE ENERGY EXPENDITURE AND VOLUME OF OXYGEN CONSUMPTION AND CARBON DIOXIDE PRODUCTION DURING A HIGH-SPEED YOGA AND A STANDARD-SPEED YOGA PROGRAM. DESIGN: RANDOMIZED REPEATED MEASURES CONTROLLED TRIAL. SETTING: A LABORATORY OF NEUROMUSCULAR RESEARCH AND ACTIVE AGING. INTERVENTIONS: SUN-SALUTATION B WAS PERFORMED, FOR EIGHT MINUTES, AT A HIGH SPEED VERSUS AND A STANDARD-SPEED SEPARATELY WHILE OXYGEN CONSUMPTION WAS RECORDED. CALORIC EXPENDITURE WAS CALCULATED USING VOLUME OF OXYGEN CONSUMPTION AND CARBON DIOXIDE PRODUCTION. MAIN OUTCOME MEASURES: DIFFERENCE IN ENERGY EXPENDITURE (KCAL) OF HSY AND SSY. RESULTS: SIGNIFICANT DIFFERENCES WERE OBSERVED IN ENERGY EXPENDITURE BETWEEN YOGA SPEEDS WITH HIGH-SPEED YOGA PRODUCING SIGNIFICANTLY HIGHER ENERGY EXPENDITURE THAN STANDARD-SPEED YOGA (MD=18.55, SE=1.86, P<0.01). SIGNIFICANT DIFFERENCES WERE ALSO SEEN BETWEEN HIGH-SPEED AND STANDARD-SPEED YOGA FOR VOLUME OF OXYGEN CONSUMED AND CARBON DIOXIDE PRODUCED. CONCLUSIONS: HIGH-SPEED YOGA RESULTS IN A SIGNIFICANTLY GREATER CALORIC EXPENDITURE THAN STANDARD-SPEED YOGA. HIGH-SPEED YOGA MAY BE AN EFFECTIVE ALTERNATIVE PROGRAM FOR THOSE TARGETING CARDIOMETABOLIC MARKERS.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
9 1305  22 HATHA YOGA PRACTICES: ENERGY EXPENDITURE, RESPIRATORY CHANGES AND INTENSITY OF EXERCISE. THE AIM OF THIS STUDY WAS TO CRITICALLY OBSERVE THE ENERGY EXPENDITURE, EXERCISE INTENSITY AND RESPIRATORY CHANGES DURING A FULL YOGA PRACTICE SESSION. OXYGEN CONSUMPTION ([FORMULA: SEE TEXT]), CARBON DIOXIDE OUTPUT ([FORMULA: SEE TEXT]), PULMONARY VENTILATION ([FORMULA: SEE TEXT]E), RESPIRATORY RATE (FR) AND TIDAL VOLUME (VT), WERE MEASURED IN 16 PHYSICAL POSTURE (ASANAS), FIVE YOGA BREATHING MANEUVERS (BM) AND TWO TYPES OF MEDITATION. TWENTY MALE (AGE 27.3 +/- 3.5 YEARS, HEIGHT 166.6 +/- 5.4 CM AND BODY WEIGHT 58.8 +/- 9.6 KG) YOGA INSTRUCTORS WERE STUDIED. THEIR MAXIMAL OXYGEN CONSUMPTION ([FORMULA: SEE TEXT]) WAS RECORDED. THE EXERCISE INTENSITY IN ASANAS WAS EXPRESSED IN PERCENTAGE [FORMULA: SEE TEXT] . IN ASANAS, EXERCISE INTENSITY VARIED FROM 9.9 TO 26.5% OF [FORMULA: SEE TEXT] . HIGHEST ENERGY COST WAS 3.02 KCAL MIN(-1). IN BM HIGHEST [FORMULA: SEE TEXT]E WAS 53.7 +/- 15.5 L MIN(-1). VT WAS 0.97 +/- 0.59, 1.41 +/- 1.27 AND 1.28 +/- L/BREATH WITH CORRESPONDING FR OF 14.0 +/- 5.3, 10.0 +/- 6.35, 10.0 +/- 5.8 BREATHS/MIN. AVERAGE ENERGY EXPENDITURE IN ASANAS, BM AND MEDITATION WERE 2.29, 1.91 AND 1.37 KCAL MIN(-1), RESPECTIVELY. METABOLIC RATE WAS GENERALLY IN THE RANGE OF 1-2 METABOLIC EQUIVALENTS (MET) EXCEPT IN THREE ASANAS WHERE IT WAS >2 MET. [FORMULA: SEE TEXT] WAS 0.27 +/- 0.05 AND 0.24 +/- 0.04 L MIN(-1) IN MEDITATION AND SHAVASANA, RESPECTIVELY. ALTHOUGH YOGIC PRACTICES ARE LOW INTENSITY EXERCISES WITHIN LACTATE THRESHOLD, PHYSICAL PERFORMANCE IMPROVEMENT IS POSSIBLE OWING TO BOTH BETTER ECONOMY OF BREATHING BY BM AND ALSO BY IMPROVEMENT IN CARDIOVASCULAR RESERVE. OTHER FACTORS SUCH AS PSYCHO-PHYSIOLOGICAL AND BETTER RELAXATION MAY CONTRIBUTE TO IT.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
10 1147  43 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
11 2193  27 THE EFFECTS OF YOGA TRAINING AND A SINGLE BOUT OF YOGA ON DELAYED ONSET MUSCLE SORENESS IN THE LOWER EXTREMITY. THE PURPOSE OF THIS STUDY WAS TO DETERMINE THE EFFECTS OF YOGA TRAINING AND A SINGLE BOUT OF YOGA ON THE INTENSITY OF DELAYED ONSET MUSCLE SORENESS (DOMS). 24 YOGA-TRAINED (YT; N = 12) AND NON-YOGA-TRAINED (CON; N = 12), MATCHED WOMEN VOLUNTEERS WERE ADMINISTERED A DOMS-INDUCING BENCH-STEPPING EXERCISE. MUSCLE SORENESS WAS ASSESSED AT BASELINE, 24, 48, 72, 96, AND 120 HOURS AFTER BENCH-STEPPING USING A VISUAL ANALOG SCALE (VAS). GROUPS WERE ALSO COMPARED ON BODY AWARENESS (BA), FLEXIBILITY USING THE SIT-AND-REACH TEST (SR), AND PERCEIVED EXERTION (RPE). STATISTICAL SIGNIFICANCE WAS ACCEPTED AT P </= 0.05. A 2 X 2 MIXED FACTORIAL ANOVA WITH REPEATED MEASURES AT 24 AND 48 HOURS REVEALED A SIGNIFICANT (P < 0.05) GROUP MAIN EFFECT WITH VAS SCORES GREATER FOR CON THAN YT. PAIRED T-TESTS REVEALED THAT IN YT, VAS SCORES WERE HIGHER BEFORE YOGA CLASS THAN AFTER YOGA CLASS AT 24 HOURS (21.4 [+/- 6.9] MM VS. 11.1 [+/- 4.1] MM; P = 0.02). THE SR WAS GREATER IN YT THAN IN CON (65.0 [+/- 7.9] CM VS. 33.3 [+/- 7.0] CM; P < 0.01); HOWEVER, NO DIFFERENCES WERE FOUND BETWEEN YOGA AND CONTROL IN BA (94.0 [+/- 4.4] UNITS VS. 83.8 [+/- 3.7] UNITS; P = 0.21) OR IN RPE AT 5-MINUTE INTERVALS (2.9 [+/- 0.3], 5.3 [+/- 0.8], 5.8 [+/- 0.9], AND 5.2 [+/- 0.8] VS. 2.5 [+/- 0.3], 4.0 [+/- 0.5], 4.2 [+/- 0.3], AND 4.9 [+/- 0.4]. YOGA TRAINING AND A SINGLE BOUT OF YOGA APPEAR TO ATTENUATE PEAK MUSCLE SORENESS IN WOMEN FOLLOWING A BOUT OF ECCENTRIC EXERCISE. THESE FINDINGS HAVE SIGNIFICANT IMPLICATIONS FOR COACHES, ATHLETES, AND THE EXERCISING PUBLIC WHO MAY WANT TO IMPLEMENT YOGA TRAINING AS A PRESEASON REGIMEN OR SUPPLEMENTAL ACTIVITY TO LESSEN THE SYMPTOMS ASSOCIATED WITH MUSCLE SORENESS.	2004	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
12  265  28 ACUTE EFFECTS OF AEROBIC EXERCISE AND HATHA YOGA ON CRAVING TO SMOKE. INTRODUCTION: RECENT STUDIES HAVE EXAMINED THE EFFECTS OF PHYSICAL ACTIVITY ON CRAVING TO SMOKE AND SMOKING WITHDRAWAL. THE CURRENT STUDY WAS DESIGNED TO COMPARE AND CONTRAST THE EFFECTS OF 2 DIFFERENT FORMS OF PHYSICAL ACTIVITY ON GENERAL AND CUE-ELICITED CRAVING TO SMOKE. METHODS: FOLLOWING 1-HR NICOTINE ABSTINENCE, 76 DAILY SMOKERS WERE RANDOMLY ASSIGNED TO ENGAGE IN A 30-MIN BOUT OF CARDIOVASCULAR EXERCISE (CE; BRISK WALK ON A TREADMILL), HATHA YOGA (HY), OR A NONACTIVITY CONTROL CONDITION. PARTICIPANTS COMPLETED MEASURES OF CRAVING AND MOOD, AND A SMOKING CUE REACTIVITY ASSESSMENT, BEFORE, IMMEDIATELY FOLLOWING, AND APPROXIMATELY 20 MIN AFTER THE PHYSICAL ACTIVITY OR CONTROL CONDITIONS. RESULTS: COMPARED WITH THE CONTROL CONDITION, PARTICIPANTS IN EACH OF THE PHYSICAL ACTIVITY GROUPS REPORTED A DECREASE IN CRAVING TO SMOKE, AN INCREASE IN POSITIVE AFFECT, AND A DECREASE IN NEGATIVE AFFECT. IN ADDITION, CRAVING IN RESPONSE TO SMOKING CUES WAS SPECIFICALLY REDUCED AMONG THOSE WHO ENGAGED IN CE, WHEREAS THOSE WHO ENGAGED IN HY REPORTED A GENERAL DECREASE IN CRAVINGS. CONCLUSIONS: THIS STUDY PROVIDES FURTHER SUPPORT FOR THE USE OF EXERCISE BOUTS FOR ATTENUATING CIGARETTE CRAVINGS DURING TEMPORARY NICOTINE ABSTINENCE. RESULTS ALSO SUGGEST THAT CE CAN ATTENUATE CRAVINGS IN RESPONSE TO SMOKING CUES.

13 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	
                                                                                    
14  266  27 ACUTE EFFECTS OF WALKING, CYCLING, AND YOGA EXERCISE ON COGNITION IN PERSONS WITH RELAPSING-REMITTING MULTIPLE SCLEROSIS WITHOUT IMPAIRED COGNITIVE PROCESSING SPEED. INTRODUCTION: COGNITIVE IMPAIRMENT IS A HIGHLY PREVALENT, DISABLING, AND POORLY MANAGED CONSEQUENCE OF MULTIPLE SCLEROSIS (MS). EXERCISE TRAINING REPRESENTS A PROMISING APPROACH FOR MANAGING COGNITIVE IMPAIRMENT IN THIS POPULATION. HOWEVER, THERE IS LIMITED EVIDENCE SUPPORTING AN OPTIMAL EXERCISE STIMULUS FOR IMPROVING COGNITION IN MS. THE CURRENT STUDY COMPARED THE ACUTE EFFECTS OF MODERATE-INTENSITY TREADMILL WALKING, MODERATE-INTENSITY CYCLE ERGOMETRY, AND GUIDED YOGA WITH THOSE OF QUIET REST ON EXECUTIVE CONTROL IN 24 PERSONS WITH RELAPSING-REMITTING MS WITHOUT IMPAIRED COGNITIVE PROCESSING SPEED USING A WITHIN-SUBJECTS, REPEATED MEASURES DESIGN. METHOD: PARTICIPANTS COMPLETED FOUR EXPERIMENTAL CONDITIONS THAT CONSISTED OF 20 MINUTES OF MODERATE-INTENSITY TREADMILL WALKING EXERCISE, MODERATE-INTENSITY CYCLE ERGOMETER EXERCISE, GUIDED YOGA, AND QUIET REST IN A RANDOMIZED, COUNTERBALANCED ORDER. PARTICIPANTS UNDERWENT A MODIFIED-FLANKER TASK AS A MEASURE OF EXECUTIVE CONTROL IMMEDIATELY PRIOR TO AND FOLLOWING EACH CONDITION. RESULTS: REPEATED MEASURES ANALYSES OF VARIANCE (ANOVAS) INDICATED GENERAL PRE-TO-POST IMPROVEMENTS IN REACTION TIME, BUT NOT ACCURACY, ON THE MODIFIED-FLANKER TASK FOR ALL THREE EXERCISE MODALITIES COMPARED WITH QUIET REST. HOWEVER, THERE WERE ADDITIONAL, SELECTIVE PRE-TO-POST REDUCTIONS IN THE COST OF INTERFERING STIMULI ON REACTION TIME ON THE MODIFIED-FLANKER TASK FOR TREADMILL WALKING, F(1, 23) = 4.67, P = .04, ETA(P)2 = .17, BUT NOT CYCLE ERGOMETRY, F(1, 23) = 0.12, P = .73, ETA(P)2 < .01, OR GUIDED YOGA, F(1, 23) = 0.73, P = .40, ETA(P)2 = .03, COMPARED WITH QUIET REST. CONCLUSIONS: THE PRESENT RESULTS SUPPORT TREADMILL WALKING AS THE MODALITY OF EXERCISE THAT MIGHT EXERT THE LARGEST BENEFICIAL EFFECTS ON EXECUTIVE CONTROL IN PERSONS WITH RELAPSING-REMITTING MS WITHOUT IMPAIRED COGNITIVE PROCESSING SPEED. THIS REPRESENTS AN EXCITING STARTING POINT FOR DELINEATING THE APPROPRIATE EXERCISE STIMULUS (I.E., MODALITY AND INTENSITY) FOR INCLUSION IN A SUBSEQUENT LONGITUDINAL EXERCISE TRAINING INTERVENTION FOR IMPROVING COGNITIVE PERFORMANCE IN THIS POPULATION.	2015	
                                                                                                                                                                                                                                                                                                
15  993   9 EFFECTS OF HEATED AND THERMONEUTRAL YOGA INTERVENTIONS ON ARTERIAL STIFFNESS IN MIDDLE-AGED ADULTS. THE STUDY INVESTIGATED THE EFFICACY OF 12 WEEKS OF HEATED AND THERMONEUTRAL BIKRAM YOGA IN REDUCING ARTERIAL STIFFNESS IN MIDDLE-AGED ADULTS. FIFTY-FOUR SEDENTARY ADULTS (AGES 40-60 YEARS) COMPLETED 12 WEEKS OF YOGA AT 40.5 DEGREES C (N = 21), YOGA AT 23 DEGREES C (N = 14) OR TIME CONTROL (N = 19). BRACHIAL-ANKLE PULSE WAVE VELOCITY (PWV) WAS NOT SIGNIFICANTLY ALTERED BY HOT OR THERMONEUTRAL YOGA INTERVENTIONS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
16  229  35 A SYSTEMATIC REVIEW OF THE ENERGY COST AND METABOLIC INTENSITY OF YOGA. PURPOSE: WITH THE INCREASING POPULARITY OF HATHA YOGA, IT IS IMPORTANT TO UNDERSTAND THE ENERGY COST AND METS OF YOGA PRACTICE WITHIN THE CONTEXT OF THE AMERICAN COLLEGE OF SPORTS MEDICINE (ACSM) AND THE AMERICAN HEART ASSOCIATION (AHA) PHYSICAL ACTIVITY GUIDELINES. METHODS: THIS SYSTEMATIC REVIEW EVALUATED THE ENERGY COST AND METABOLIC INTENSITY OF YOGA PRACTICE INCLUDING YOGA ASANAS (POSES/POSTURES) AND PRANAYAMAS (BREATH EXERCISES) MEASURED BY INDIRECT CALORIMETRY. THE ENGLISH-SPEAKING LITERATURE WAS SURVEYED VIA PUBMED USING THE GENERAL TERMS "YOGA" AND "ENERGY EXPENDITURE" WITH NO DATE LIMITATIONS. RESULTS: THIRTEEN MANUSCRIPTS WERE INITIALLY IDENTIFIED WITH AN ADDITIONAL FOUR LOCATED FROM REVIEW OF MANUSCRIPT REFERENCES. OF THE 17 STUDIES, 10 EVALUATED THE ENERGY COST AND METS OF FULL YOGA SESSIONS OR FLOW THROUGH SURYA NAMASKAR (SUN SALUTATIONS), EIGHT OF INDIVIDUAL ASANAS, AND FIVE OF PRANAYAMAS. METS FOR YOGA PRACTICE AVERAGED 3.3 +/- 1.6 (RANGE = 1.83-7.4 METS) AND 2.9 +/- 0.8 METS WHEN ONE OUTLIER (I.E., 7.4 METS FOR SURYA NAMASKAR) WAS OMITTED. METS FOR INDIVIDUAL ASANAS AVERAGED 2.2 +/- 0.7 (RANGE = 1.4-4.0 METS), WHEREAS THAT OF PRANAYAMAS WAS 1.3 +/- 0.3. ON THE BASIS OF ACSM/AHA CLASSIFICATION, THE INTENSITY OF MOST ASANAS AND FULL YOGA SESSIONS RANGED FROM LIGHT (LESS THAN 3 METS) TO MODERATE AEROBIC INTENSITY (3-6 METS), WITH THE MAJORITY CLASSIFIED AS LIGHT INTENSITY. CONCLUSION: THIS REVIEW SUGGESTS THAT YOGA IS TYPICALLY CLASSIFIED AS A LIGHT-INTENSITY PHYSICAL ACTIVITY. HOWEVER, A FEW SEQUENCES/POSES, INCLUDING SURYA NAMASKAR, MEET THE CRITERIA FOR MODERATE- TO VIGOROUS-INTENSITY ACTIVITY. IN ACCORDANCE WITH THE ACSM/AHA GUIDELINES, THE PRACTICE OF ASANA SEQUENCES WITH MET INTENSITIES HIGHER THAN THREE (I.E., >10 MIN) CAN BE ACCUMULATED THROUGHOUT THE DAY AND COUNT TOWARD DAILY RECOMMENDATIONS FOR MODERATE- OR VIGOROUS-INTENSITY PHYSICAL ACTIVITY.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
17 1451  26 INFLUENCE OF INTENSIVE YOGA TRAINING ON PHYSIOLOGICAL CHANGES IN 6 ADULT WOMEN: A CASE REPORT. THE SHORT-TERM EFFECTS OF 4 WEEKS OF INTENSIVE YOGA PRACTICE ON PHYSIOLOGICAL RESPONSES IN SIX HEALTHY ADULT FEMALE VOLUNTEERS WERE MEASURED USING THE MAXIMAL EXERCISE TREADMILL TEST. YOGA PRACTICE INVOLVED DAILY MORNING AND EVENING SESSIONS OF 90 MINUTES EACH. PRE- AND POST-YOGA EXERCISE PERFORMANCE WAS COMPARED. MAXIMAL WORK OUTPUT (WMAX) FOR THE GROUP INCREASED BY 21%, WITH A SIGNIFICANTLY REDUCED LEVEL OF OXYGEN CONSUMPTION PER UNIT WORK BUT WITHOUT A CONCOMITANT SIGNIFICANT CHANGE IN HEART RATE. AFTER INTENSIVE YOGA TRAINING, AT 154 WMIN(-1) (CORRESPONDING TO WMAX OF THE PRE-YOGA MAXIMAL EXERCISE TEST) PARTICIPANTS COULD EXERCISE MORE COMFORTABLY, WITH A SIGNIFICANTLY LOWER HEART RATE (P < 0.05), REDUCED MINUTE VENTILATION (P < 0.05), REDUCED OXYGEN CONSUMPTION PER UNIT WORK (P < 0.05), AND A SIGNIFICANTLY LOWER RESPIRATORY QUOTIENT (P < 0.05). THE IMPLICATIONS FOR THE EFFECT OF INTENSIVE YOGA ON CARDIORESPIRATORY EFFICIENCY ARE DISCUSSED, WITH THE SUGGESTION THAT YOGA HAS SOME TRANSPARENTLY DIFFERENT QUANTIFIABLE PHYSIOLOGICAL EFFECTS TO OTHER EXERCISES.	1997

PATIENTS AND METHODS: THIRTY-ONE MS PATIENTS, ALL FEMALE WITH MEAN OF AGE OF 36.75 YEARS AND EXPANDED DISABILITY STATUS SCALE SCORES (EDSS) OF 1.0 TO 4.0 WERE RECRUITED. SUBJECTS WERE RANDOMLY ASSIGNED TO ONE OF THE THREE GROUPS: TREADMILL TRAINING, YOGA OR CONTROL GROUPS. TREADMILL TRAINING AND YOGA PRACTICE CONSISTED OF 8 WEEKS (24 SESSIONS, THRICE WEEKLY). THE CONTROL GROUP FOLLOWED THEIR OWN ROUTINE TREATMENT PROGRAM. BALANCE, SPEED AND ENDURANCE OF WALKING, FATIGUE, DEPRESSION AND ANXIETY WERE MEASURED BY BERG BALANCE SCORES, TIME FOR 10M WALK AND DISTANCE FOR A TWO MINUTE WALK, FATIGUE SEVERITY SCALE (FFS), BECK DEPRESSION INVENTORY (BDI) AND BECK ANXIETY INVENTORY (BAI), RESPECTIVELY. RESULTS: COMPARISON OF RESULTS HAVE SHOWN THAT PRE- AND POST-INTERVENTIONS PRODUCED SIGNIFICANT IMPROVEMENTS IN THE BALANCE SCORE, WALKING ENDURANCE, FFS SCORE, BDI SCORE AND BAI SCORE IN THE TREADMILL TRAINING GROUP AND YOGA GROUP. HOWEVER, 10M WALK TIME DECREASED IN THE TREADMILL TRAINING GROUP BUT DID NOT SHOW ANY CLEAR CHANGE IN THE YOGA GROUP. MOREOVER, THE ANALYSIS SHOWED SIGNIFICANT DIFFERENCES BETWEEN THE TREADMILL TRAINING GROUP AND YOGA GROUP FOR BAI SCORE. CONCLUSIONS: THESE RESULTS SUGGEST THAT TREADMILL TRAINING AND YOGA PRACTICE IMPROVED AMBULATORY FUNCTION, FATIGUE AND MOOD STATUS IN THE INDIVIDUALS WITH MILD TO MODERATE MS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
19  943  27 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
20 1045  25 EFFECTS OF YOGA INTERVENTIONS PRACTISED IN HEATED AND THERMONEUTRAL CONDITIONS ON ENDOTHELIUM-DEPENDENT VASODILATATION: THE BIKRAM YOGA HEART STUDY. NEW FINDINGS: WHAT IS THE CENTRAL QUESTION OF THIS STUDY? DOES THE HEATED PRACTICE ENVIRONMENT ENHANCE THE EFFECTS OF BIKRAM YOGA ON ENDOTHELIUM-DEPENDENT VASODILATATION IN HEALTHY, MIDDLE-AGED ADULTS? WHAT IS THE MAIN FINDING AND ITS IMPORTANCE? THE PRIMARY FINDING FROM THIS INVESTIGATION IS THAT THE HATHA YOGA POSTURES IN THE BIKRAM YOGA SERIES PRODUCE SIMILAR ENHANCEMENTS IN ENDOTHELIUM-DEPENDENT VASODILATATION IN HEALTHY, MIDDLE-AGED ADULTS REGARDLESS OF ENVIRONMENTAL TEMPERATURE. THESE FINDINGS HIGHLIGHT THE EFFICACY OF YOGA POSTURES IN PRODUCING IMPROVEMENTS IN VASCULAR HEALTH AND DOWNPLAY THE NECESSITY OF THE HEATED PRACTICE ENVIRONMENT IN INDUCING VASCULAR ADAPTATIONS. ABSTRACT: WE HAVE PREVIOUSLY DOCUMENTED IMPROVEMENTS IN ENDOTHELIUM-DEPENDENT VASODILATATION WITH A BIKRAM (HOT) YOGA INTERVENTION IN MIDDLE-AGED ADULTS. AT PRESENT, THE EFFECT OF ENVIRONMENTAL TEMPERATURE IN HOT YOGA ON ENDOTHELIAL FUNCTION IS UNKNOWN. THE PURPOSE OF THIS INVESTIGATION WAS TO DETERMINE THE EFFECTS OF BIKRAM YOGA INTERVENTIONS PERFORMED IN HEATED OR THERMONEUTRAL CONDITIONS ON ENDOTHELIUM-DEPENDENT VASODILATATION. FIFTY-TWO SEDENTARY BUT APPARENTLY HEALTHY ADULTS AGED 40-60 YEARS WERE RANDOMLY ASSIGNED TO ONE OF THREE GROUPS: BIKRAM YOGA PRACTISED AT 40.5 DEGREES C (N = 19), BIKRAM YOGA PRACTISED AT 23 DEGREES C (N = 14) OR SEDENTARY TIME CONTROL (N = 19). THE YOGA INTERVENTIONS CONSISTED OF 90 MIN BIKRAM YOGA CLASSES THREE TIMES A WEEK FOR 12 WEEKS. ENDOTHELIUM-DEPENDENT VASODILATATION WAS MEASURED NON-INVASIVELY USING BRACHIAL ARTERY FLOW-MEDIATED DILATATION (FMD). BODY FAT PERCENTAGE DETERMINED VIA DUAL-ENERGY X-RAY ABSORPTIOMETRY WAS SIGNIFICANTLY LOWER IN THE HOT YOGA GROUP AFTER THE INTERVENTION THAN IN THE THERMONEUTRAL YOGA AND CONTROL CONDITIONS. BRACHIAL ARTERY FMD INCREASED (P < 0.05) IN THE THERMONEUTRAL YOGA GROUP AND TENDED TO INCREASE IN THE HOT YOGA GROUP (P = 0.056). NO CHANGES OCCURRED IN THE CONTROL GROUP. THERE WERE NO SIGNIFICANT DIFFERENCES IN FMD CHANGE SCORES BETWEEN GROUPS. WE CONCLUDE THAT BIKRAM YOGA PRACTISED IN THERMONEUTRAL CONDITIONS IMPROVED ENDOTHELIUM-DEPENDENT VASODILATATION IN HEALTHY, MIDDLE-AGED ADULTS. THESE NEW FINDINGS HIGHLIGHT THE EFFECTIVENESS OF HATHA YOGA POSTURES ALONE, IN THE ABSENCE OF A HEATED PRACTICE ENVIRONMENT, IN IMPROVING VASCULAR HEALTH AND ARE OF CLINICAL SIGNIFICANCE GIVEN THE INCREASED PROPENSITY FOR HEAT INTOLERANCE IN AGEING ADULTS.	2018
