1 1676 127 OBJECTIVE AND SUBJECTIVE MEASURES OF EXERCISE INTENSITY DURING THERMO-NEUTRAL AND HOT YOGA. WHILE HOT YOGA HAS GAINED ENORMOUS POPULARITY IN RECENT YEARS, OWING IN PART TO INCREASED ENVIRONMENTAL CHALLENGE ASSOCIATED WITH EXERCISE IN THE HEAT, IT IS NOT CLEAR WHETHER HOT YOGA IS MORE VIGOROUS THAN THERMO-NEUTRAL YOGA. THEREFORE, THE AIM OF THIS STUDY WAS TO DETERMINE OBJECTIVE AND SUBJECTIVE MEASURES OF EXERCISE INTENSITY DURING CONSTANT INTENSITY YOGA IN A HOT AND THERMO-NEUTRAL ENVIRONMENT. USING A RANDOMIZED, CROSSOVER DESIGN, 14 PARTICIPANTS COMPLETED 2 IDENTICAL APPROXIMATELY 20-MIN YOGA SESSIONS IN A HOT (35.3 +/- 0.8 DEGREES C; HUMIDITY: 20.5% +/- 1.4%) AND THERMO-NEUTRAL (22.1 +/- 0.2 DEGREES C; HUMIDITY: 27.8% +/- 1.6%) ENVIRONMENT. OXYGEN CONSUMPTION AND HEART RATE (HR) WERE RECORDED AS OBJECTIVE MEASURES (PERCENTAGE OF MAXIMAL OXYGEN CONSUMPTION AND PERCENTAGE OF MAXIMAL HR (%HRMAX)) AND RATING OF PERCEIVED EXERTION (RPE) WAS RECORDED AS A SUBJECTIVE MEASURE OF EXERCISE INTENSITY. THERE WAS NO DIFFERENCE IN EXERCISE INTENSITY BASED ON PERCENTAGE OF MAXIMAL OXYGEN CONSUMPTION DURING HOT VERSUS THERMO-NEUTRAL YOGA (30.9% +/- 2.3% VS. 30.5% +/- 1.8%, P = 0.68). HOWEVER, EXERCISE INTENSITY WAS SIGNIFICANTLY HIGHER DURING HOT VERSUS THERMO-NEUTRAL YOGA BASED ON %HRMAX (67.0% +/- 2.3% VS. 60.8% +/- 1.9%, P = 0.01) AND RPE (12 +/- 1 VS. 11 +/- 1, P = 0.04). ACCORDING TO ESTABLISHED EXERCISE INTENSITIES, HOT YOGA WAS CLASSIFIED AS LIGHT-INTENSITY EXERCISE BASED ON PERCENTAGE OF MAXIMAL OXYGEN CONSUMPTION BUT MODERATE-INTENSITY EXERCISE BASED ON %HRMAX AND RPE WHILE THERMO-NEUTRAL YOGA WAS CLASSIFIED AS LIGHT-INTENSITY EXERCISE BASED ON PERCENTAGE OF MAXIMAL OXYGEN UPTAKE, %HRMAX, AND RPE. DESPITE THE ADDED HEMODYNAMIC STRESS AND PERCEPTION THAT YOGA IS MORE STRENUOUS IN A HOT ENVIRONMENT, WE OBSERVED SIMILAR OXYGEN CONSUMPTION DURING HOT VERSUS THERMO-NEUTRAL YOGA, CLASSIFYING BOTH EXERCISE MODALITIES AS LIGHT-INTENSITY EXERCISE.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
2  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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
3   23  36 #MINDINBODY - FEASIBILITY OF VIGOROUS EXERCISE (BIKRAM YOGA VERSUS HIGH INTENSITY INTERVAL TRAINING) TO IMPROVE PERSISTENT PAIN IN WOMEN WITH A HISTORY OF TRAUMA: A PILOT RANDOMIZED CONTROL TRIAL. BACKGROUND: THE NEUROBIOLOGY OF PERSISTENT PAIN SHARES COMMON UNDERLYING PSYCHOBIOLOGY WITH THAT OF TRAUMATIC STRESS. MODERN TREATMENTS FOR TRAUMATIC STRESS OFTEN INVOLVE BOTTOM-UP SENSORIMOTOR RETRAINING/EXPOSURE THERAPIES, WHERE BREATH, MOVEMENT, BALANCE AND MINDFULNESS, ARE USED TO TARGET UNDERLYING PSYCHOBIOLOGY. VIGOROUS EXERCISE, IN PARTICULAR BIKRAM YOGA, COMBINES MANY OF THESE SENSORIMOTOR/EXPOSURE THERAPEUTIC FEATURES. HOWEVER, THERE IS VERY LITTLE RESEARCH INVESTIGATING THE FEASIBILITY AND EFFICACY OF SUCH TREATMENTS FOR TARGETING THE UNDERLYING PSYCHOBIOLOGY OF PERSISTENT PAIN. METHODS: THIS STUDY WAS A RANDOMIZED CONTROLLED TRAIL (RCT) COMPARING THE EFFICACY OF BIKRAM YOGA VERSUS HIGH INTENSITY INTERVAL TRAINING (HIIT), FOR IMPROVING PERSISTENT PAIN IN WOMEN AGED 20 TO 50 YEARS. THE PARTICIPANTS WERE 1:1 RANDOMIZED TO ATTEND THEIR ASSIGNED INTERVENTION, 3 TIMES PER WEEK, FOR 8 WEEKS. THE PRIMARY OUTCOME MEASURE WAS THE BRIEF PAIN INVENTORY (BPI) AND FURTHER PAIN RELATED BIOPSYCHOSOCIAL SECONDARY OUTCOMES, INCLUDING SF-36 MEDICAL OUTCOMES AND HEART RATE VARIABILITY (HRV), WERE ALSO EXPLORED. DATA WAS COLLECTED PRE (T0) AND POST (T1) INTERVENTION VIA AN ONLINE QUESTIONNAIRE AND PHYSIOLOGICAL TESTING. RESULTS: A TOTAL OF 34 WOMEN WERE RECRUITED FROM THE COMMUNITY. ANALYSES USING ANCOVA DEMONSTRATED NO SIGNIFICANT DIFFERENCE IN BPI (SEVERITY PLUS INTERFERENCE) SCORES BETWEEN THE BIKRAM YOGA (N = 17) AND THE HIIT (N = 15). WOMEN IN THE BIKRAM YOGA GROUP DEMONSTRATED SIGNIFICANTLY IMPROVED SF-36 SUBSCALE PHYSICAL FUNCTIONING: [ANCOVA: F(1, 29) = 6.17, P = .019, PARTIAL ETA-SQUARED EFFECT SIZE (ETAP(2)) = .175 AND MENTAL HEALTH: F(1, 29) = 9.09, P = .005, ETAP(2) = .239; AND INCREASED HEART RATE VARIABILITY (SDNN): F(1, 29) = 5.12, P = .013, ETAP(2) = .150, SCORES COMPARED TO THE HIIT GROUP. ACROSS BOTH GROUPS, PAIN WAS SHOWN TO DECREASE, NO INJURIES WERE EXPERIENCED AND RETENTION RATES WERE 94% FOR BIKRAM YOGA AND 75% FOR HIIT . CONCLUSIONS: BIKRAM YOGA DOES NOT APPEAR A SUPERIOR EXERCISE COMPARED TO HIIT FOR PERSISTENT PAIN. HOWEVER, IMPORVEMENTS IN QUALITY OF LIFE MEASURES AND INDICATOR OF BETTER HEALTH WERE SEEN IN THE BIKRAM YOGA GROUP. THE OUTCOMES OF THE PRESENT STUDY SUGGEST VIGOROUS EXERCISE INTERVENTIONS IN PERSISTENT PAIN COHORTS ARE FEASIBLE.

4 1316  30 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
5   71  32 A FEASIBILITY STUDY OF RESTORATIVE YOGA VERSUS VIGOROUS YOGA INTERVENTION FOR SEDENTARY BREAST AND OVARIAN CANCER SURVIVORS. YOGA HAS BEEN SHOWN TO IMPROVE CANCER SURVIVORS' QUALITY OF LIFE, YET REGULAR YOGA PRACTICE IS A CHALLENGE FOR THOSE WHO ARE SEDENTARY. WE CONDUCTED A PILOT RANDOMIZED CONTROLLED STUDY TO ASSESS FEASIBILITY AND ADHERENCE OF TWO TYPES OF YOGA INTERVENTION AMONG SEDENTARY CANCER SURVIVORS. SEDENTARY BREAST AND OVARIAN CANCER SURVIVORS WERE RANDOMIZED TO PRACTICE EITHER RESTORATIVE YOGA (MINIMAL PHYSICAL EXERTION, GROUP R) OR VIGOROUS YOGA (CONSIDERABLE PHYSICAL EXERTION, GROUP V) IN THREE 60-MINUTE SUPERVISED SESSIONS A WEEK FOR 12 WEEKS, FOLLOWED BY 12 WEEKS OF HOME PRACTICE. ACCRUAL, ADHERENCE, AND ATTENDANCE RATES WERE ASSESSED. OF THE 226 ELIGIBLE PATIENTS, 175 (77%) DECLINED TO PARTICIPATE IN THE STUDY, CITING TIME COMMITMENT AND TRAVEL AS THE MOST COMMON BARRIERS. FORTY-TWO SUBJECTS CONSENTED TO PARTICIPATE IN THE STUDY. OF THE 35 PARTICIPANTS WHO BEGAN THE INTERVENTION (20 IN GROUP R AND 15 IN GROUP V), ADHERENCE RATE (PERCENTAGE REMAINING IN THE STUDY AT WEEK 12) WAS 100% AND 87%, RESPECTIVELY. RATE OF ADEQUATE ATTENDANCE (MORE THAN 66% OF THE SCHEDULED SUPERVISED SESSIONS) WAS 85% AND 73%, RESPECTIVELY. RATE OF COMPLETION OF THE HOME PRACTICE PERIOD WAS 85% AND 77%, RESPECTIVELY. IN THIS STUDY, SEDENTARY CANCER SURVIVORS WERE ABLE TO ADHERE TO A LONG-TERM, REGULAR YOGA REGIMEN. THE RATE OF ADEQUATE ATTENDANCE WAS HIGHER FOR RESTORATIVE YOGA. FUTURE STUDIES FOR SEDENTARY PATIENTS SHOULD FOCUS ON REDUCING TIME COMMITMENT AND TRAVEL REQUIREMENTS TO IMPROVE RECRUITMENT, AND ON USING RESTORATIVE YOGA AS A MORE FEASIBLE INTERVENTION FOR THIS POPULATION.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
6 1497  39 INTRADIALYTIC LAUGHTER YOGA THERAPY FOR HAEMODIALYSIS PATIENTS: A PRE-POST INTERVENTION FEASIBILITY STUDY. BACKGROUND: LAUGHTER YOGA CONSISTS OF PHYSICAL EXERCISE, RELAXATION TECHNIQUES AND SIMULATED VIGOROUS LAUGHTER. IT HAS BEEN ASSOCIATED WITH PHYSICAL AND PSYCHOLOGICAL BENEFITS FOR PEOPLE IN DIVERSE CLINICAL AND NON-CLINICAL SETTINGS, BUT HAS NOT YET BEEN TESTED IN A HAEMODIALYSIS SETTING. THE STUDY HAD THREE AIMS: 1) TO EXAMINE THE FEASIBILITY OF CONDUCTING LAUGHTER YOGA FOR PATIENTS WITH END STAGE KIDNEY DISEASE IN A DIALYSIS SETTING; 2) TO EXPLORE THE PSYCHOLOGICAL AND PHYSIOLOGICAL IMPACT OF LAUGHTER YOGA FOR THESE PATIENTS; AND 3) TO ESTIMATE THE SAMPLE SIZE REQUIRED FOR FUTURE RESEARCH. METHODS: PRE/POST INTERVENTION FEASIBILITY STUDY. EIGHTEEN PARTICIPANTS WERE RECRUITED INTO THE STUDY AND LAUGHTER YOGA THERAPISTS PROVIDED A FOUR WEEK INTRADIALYTIC PROGRAM (30-MIN INTERVENTION THREE TIMES PER WEEK). PRIMARY OUTCOMES WERE PSYCHOLOGICAL ITEMS MEASURED AT THE FIRST AND LAST LAUGHTER YOGA SESSION, INCLUDING: QUALITY OF LIFE; SUBJECTIVE WELLBEING; MOOD; OPTIMISM; CONTROL; SELF-ESTEEM; DEPRESSION, ANXIETY AND STRESS. SECONDARY OUTCOMES WERE: BLOOD PRESSURE, INTRADIALYTIC HYPOTENSIVE EPISODES AND LUNG FUNCTION (FORCED EXPIRATORY VOLUME). DIALYSIS NURSES EXPOSED TO THE INTERVENTION COMPLETED A LAUGHTER YOGA ATTITUDES AND PERCEPTIONS SURVEY (N = 11). DATA WERE ANALYSED USING IBM SPSS STATISTICS V22, INCLUDING DESCRIPTIVE AND INFERENTIAL STATISTICS, AND SAMPLE SIZE ESTIMATES WERE CALCULATED USING G*POWER. RESULTS: ONE PARTICIPANT WITHDREW FROM THE STUDY FOR MEDICAL REASONS THAT WERE UNRELATED TO THE STUDY DURING THE FIRST WEEK (94 % RETENTION RATE). THERE WERE NON-SIGNIFICANT INCREASES IN HAPPINESS, MOOD, AND OPTIMISM AND A DECREASE IN STRESS. EPISODES OF INTRADIALYTIC HYPOTENSION DECREASED FROM 19 PRE AND 19 DURING LAUGHTER YOGA TO 4 POST LAUGHTER YOGA. THERE WAS NO CHANGE IN LUNG FUNCTION OR BLOOD PRESSURE. ALL NURSES AGREED OR STRONGLY AGREED THAT LAUGHTER YOGA HAD A POSITIVE IMPACT ON PATIENTS' MOOD, IT WAS A FEASIBLE INTERVENTION AND THEY WOULD RECOMMEND LAUGHTER YOGA TO THEIR PATIENTS. SAMPLE SIZE CALCULATIONS FOR FUTURE RESEARCH INDICATED THAT A MINIMUM OF 207 PARTICIPANTS WOULD BE REQUIRED TO PROVIDE SUFFICIENT POWER TO DETECT CHANGE IN KEY PSYCHOLOGICAL VARIABLES. CONCLUSIONS: THIS STUDY PROVIDES EVIDENCE THAT LAUGHTER YOGA IS A SAFE, LOW-INTENSITY FORM OF INTRADIALYTIC PHYSICAL ACTIVITY THAT CAN BE SUCCESSFULLY IMPLEMENTED FOR PATIENTS IN DIALYSIS SETTINGS. LARGER STUDIES ARE REQUIRED, HOWEVER, TO DETERMINE THE EFFECT OF LAUGHTER YOGA ON KEY PSYCHOLOGICAL VARIABLES.

7 1147  39 ENERGY EXPENDITURE DURING A VINYASA YOGA SESSION. BACKGROUND: VINYASA YOGA HAS BEEN RECENTLY PROMOTED AS ONE OF THE MOST POPULAR MINDFUL EXERCISES TO IMPROVE OVERALL HEALTH, INCLUDING BODY WEIGHT MANAGEMENT. THE PURPOSE OF THIS STUDY WAS TO DETERMINE THE METABOLIC RESPONSE OF 24 MODERATELY TRAINED INDIVIDUALS DURING A 90-MIN GROUP VINYASA YOGA ROUTINE. METHODS: HEART RATE (HR) TIME COURSE OF 12 MALES AND 12 FEMALES (AGE: 39+/-7.33 YEARS) WAS RECORDED DURING TWO GROUP VINYASA YOGA SESSIONS CONSISTED OF FOUR SECTIONS (WARM-UP, HIGH-INTENSITY SURYA NAMASKAR (HSN), NO SURYA NAMASKAR POSTURES, AND COOL-DOWN). MAXIMAL OXYGEN UPTAKE (VO<INF>2PEAK</INF>) AND MAXIMUM HR HAD BEEN ESTIMATED EARLIER AFTER A MAXIMAL TREADMILL TEST. VO<INF>2</INF> DURING VINYASA YOGA SESSIONS WAS ESTIMATED FROM INDIVIDUAL REGRESSION EQUATIONS USING THE RELATIONSHIP OF VO<INF>2</INF> AND HR VALUES DERIVED FROM VO<INF>2PEAK</INF> TEST, WHILE THE METABOLIC RATE (KCAL/MIN) WAS CALCULATED FROM THE RELATIONSHIP OF HR AND KCAL/MIN. TOTAL SESSION ENERGY CONSUMPTION WAS THE AVERAGE VALUE OF THE TWO YOGA SESSIONS. RESULTS: THE 2 (GENDER) X 4 (SECTIONS) MIXED ANOVA REVEALED NO SIGNIFICANT INTERACTION BETWEEN THE TWO FACTORS (P=0.101) FOR THE MEAN METABOLIC RATE (7.1+/-2.6 KCAL/MIN). MEAN METABOLIC RATE THOUGHT WAS HIGHER (P=0.015) IN MALES COMPARED TO FEMALES AT EACH SECTION. ALSO, SIGNIFICANT DIFFERENCES WERE FOUND AMONG THE FOUR VINYASA YOGA SECTIONS (P<0.001) IN THE RATE OF ENERGY EXPENDITURE, WITH HSN PRESENTING THE HIGHEST MEAN VALUES (P<0.05). CONCLUSIONS: IT SEEMS THAT SYSTEMATIC PARTICIPATION IN VINYASA YOGA MAY EFFECTIVELY IMPROVE CARDIORESPIRATORY FITNESS AND PROMOTE BODY WEIGHT LOSS, AS AN ALTERNATIVE METHOD TO TRADITIONAL AEROBIC EXERCISE.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
8  642  36 DOES PRACTICING HATHA YOGA SATISFY RECOMMENDATIONS FOR INTENSITY OF PHYSICAL ACTIVITY WHICH IMPROVES AND MAINTAINS HEALTH AND CARDIOVASCULAR FITNESS? BACKGROUND: LITTLE IS KNOWN ABOUT THE METABOLIC AND HEART RATE RESPONSES TO A TYPICAL HATHA YOGA SESSION. THE PURPOSES OF THIS STUDY WERE 1) TO DETERMINE WHETHER A TYPICAL YOGA PRACTICE USING VARIOUS POSTURES MEETS THE CURRENT RECOMMENDATIONS FOR LEVELS OF PHYSICAL ACTIVITY REQUIRED TO IMPROVE AND MAINTAIN HEALTH AND CARDIOVASCULAR FITNESS; 2) TO DETERMINE THE RELIABILITY OF METABOLIC COSTS OF YOGA ACROSS SESSIONS; 3) TO COMPARE THE METABOLIC COSTS OF YOGA PRACTICE TO THOSE OF TREADMILL WALKING. METHODS: IN THIS OBSERVATIONAL STUDY, 20 INTERMEDIATE-TO-ADVANCED LEVEL YOGA PRACTITIONERS, AGE 31.4 +/- 8.3 YEARS, PERFORMED AN EXERCISE ROUTINE INSIDE A HUMAN RESPIRATORY CHAMBER (INDIRECT CALORIMETER) WHILE WEARING HEART RATE MONITORS. THE EXERCISE ROUTINE CONSISTED OF 30 MINUTES OF SITTING, 56 MINUTES OF BEGINNER-LEVEL HATHA YOGA ADMINISTERED BY VIDEO, AND 10 MINUTES OF TREADMILL WALKING AT 3.2 AND 4.8 KPH EACH. MEASURES WERE MEAN OXYGEN CONSUMPTION (VO2), HEART RATE (HR), PERCENTAGE PREDICTED MAXIMAL HEART RATE (%MHR), METABOLIC EQUIVALENTS (METS), AND ENERGY EXPENDITURE (KCAL). SEVEN SUBJECTS REPEATED THE PROTOCOL SO THAT MEASUREMENT RELIABILITY COULD BE ESTABLISHED. RESULTS: MEAN VALUES ACROSS THE ENTIRE YOGA SESSION FOR VO2, HR, %MHR, METS, AND ENERGY/MIN WERE 0.6 L/KG/MIN; 93.2 BEATS/MIN; 49.4%; 2.5; AND 3.2 KCAL/MIN; RESPECTIVELY. RESULTS OF THE ICCS (2,1) FOR MEAN VALUES ACROSS THE ENTIRE YOGA SESSION FOR KCAL, METS, AND %MHR WERE 0.979 AND 0.973, AND 0.865, RESPECTIVELY. CONCLUSION: METABOLIC COSTS OF YOGA AVERAGED ACROSS THE ENTIRE SESSION REPRESENT LOW LEVELS OF PHYSICAL ACTIVITY, ARE SIMILAR TO WALKING ON A TREADMILL AT 3.2 KPH, AND DO NOT MEET RECOMMENDATIONS FOR LEVELS OF PHYSICAL ACTIVITY FOR IMPROVING OR MAINTAINING HEALTH OR CARDIOVASCULAR FITNESS. YOGA PRACTICE INCORPORATING SUN SALUTATION POSTURES EXCEEDING THE MINIMUM BOUT OF 10 MINUTES MAY CONTRIBUTE SOME PORTION OF SUFFICIENTLY INTENSE PHYSICAL ACTIVITY TO IMPROVE CARDIO-RESPIRATORY FITNESS IN UNFIT OR SEDENTARY INDIVIDUALS. THE MEASUREMENT OF ENERGY EXPENDITURE ACROSS YOGA SESSIONS IS HIGHLY RELIABLE.	2007	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
9  978  27 EFFECTS OF BODY-ORIENTED YOGA: A RCT STUDY FOR PATIENTS WITH MAJOR DEPRESSIVE DISORDER. THE MAJOR DEPRESSIVE DISORDER IS ONE OF THE MOST COMMON MENTAL ILLNESSES WORLDWIDE. CURRENT TREATMENT STANDARDS RECOMMEND A COMBINED THERAPY WITH MEDICATION AND PSYCHOTHERAPY. AS AN ADDITIVE COMPONENT AND TO FURTHER IMPROVEMENTS IN TREATMENT, PHYSICAL ACTIVITY SUCH AS YOGA MAY BE INTEGRATED INTO CONVENTIONAL TREATMENT. THIS STUDY INVESTIGATES THE IMPACT OF A 3-MONTH BODY-ORIENTED YOGA IN PATIENTS WITH MAJOR DEPRESSIVE DISORDER (MDD). IN TOTAL, N = 83 PATIENTS WERE INCLUDED. AN INTERVENTION GROUP RECEIVED A VIGOROUS ASHTANGA-YOGA THREE TIMES A WEEK. THE WAITING-LIST CONTROL GROUP OBTAINED A TREATMENT AS USUAL (TAU). AS A PRIMARY OUTCOME DEPRESSION SCORES (BECK DEPRESSION INVENTORY-II (BDI-II), MONTGOMERY ASBERG DEPRESSION RATING SCALE (MADRS)) WERE TESTED AT THREE TIME POINTS. SECONDARY OUTCOME WAS THE POSITIVE AND NEGATIVE AFFECT [POSITIVE AND NEGATIVE AFFECT SCALE (PANAS)] AND REMISSION RATES. TO ANALYZE THE DATA, MULTILEVEL MODELS AND EFFECT SIZES WERE CONDUCTED. THE RESULTS SHOWED AN IMPROVEMENT IN BDI-II SCORES FOR BOTH GROUPS OVER TIME [GAMMA = - 3.46, T(165) = - 7.99, P < 0.001] BUT NOT BETWEEN GROUPS [GAMMA = 0.98, T(164) = 1.12, P = 0.263]. AN INTERACTION EFFECT (TIME X GROUP) OCCURRED FOR MADRS [GAMMA = 2.10, T(164) = 2.10, P < 0.038]. POSITIVE AFFECTS IMPROVED OVER TIME FOR BOTH GROUPS [GAMMA = 1.65, T(165) = 4.03, P < 0.001]. NEGATIVE AFFECTS DECREASED FOR ALL OVER TIME [GAMMA = - 1.00, T(165) = - 2.51, P = 0.013]. THERE WERE NO SIGNIFICANT GROUP DIFFERENCES IN PANAS. POST HOC TESTS REVEALED A GREATER SYMPTOM REDUCTION WITHIN THE FIRST 6 WEEKS FOR ALL MEASUREMENTS. THE EFFECT SIZES FOR DEPRESSION SCORES SHOWED A POSITIVE TREND. REMISSION RATES INDICATED A SIGNIFICANT IMPROVEMENT IN THE YOGA GROUP (BDI-II: 46.81%, MADRS: 17.02%) COMPARED TO THE CONTROL GROUP (BDI: 33.33%, MADRS: 8.33%). THE FINDINGS SUGGEST THAT THERE IS A TRENDSETTING ADDITIVE EFFECT OF ASHTANGA-YOGA AFTER 3 MONTHS ON PSYCHOPATHOLOGY AND MOOD WITH A GREATER IMPROVEMENT AT THE BEGINNING OF THE INTERVENTION. FURTHER RESEARCH IN THIS FIELD CAN HELP TO ACHIEVE MORE DIFFERENTIATED RESULTS.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
10  668  33 EFFECT OF A 16-WEEK BIKRAM YOGA PROGRAM ON HEART RATE VARIABILITY AND ASSOCIATED CARDIOVASCULAR DISEASE RISK FACTORS IN STRESSED AND SEDENTARY ADULTS: A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: CHRONIC ACTIVATION OF THE STRESS-RESPONSE CAN CONTRIBUTE TO CARDIOVASCULAR DISEASE RISK, PARTICULARLY IN SEDENTARY INDIVIDUALS. THIS STUDY INVESTIGATED THE EFFECT OF A BIKRAM YOGA INTERVENTION ON THE HIGH FREQUENCY POWER COMPONENT OF HEART RATE VARIABILITY (HRV) AND ASSOCIATED CARDIOVASCULAR DISEASE (CVD) RISK FACTORS (I.E. ADDITIONAL DOMAINS OF HRV, HEMODYNAMIC, HEMATOLOGIC, ANTHROPOMETRIC AND BODY COMPOSITION OUTCOME MEASURES) IN STRESSED AND SEDENTARY ADULTS. METHODS: ELIGIBLE ADULTS WERE RANDOMIZED TO AN EXPERIMENTAL GROUP (N = 29) OR A NO TREATMENT CONTROL GROUP (N = 34). EXPERIMENTAL GROUP PARTICIPANTS WERE INSTRUCTED TO ATTEND THREE TO FIVE SUPERVISED BIKRAM YOGA CLASSES PER WEEK FOR 16 WEEKS AT LOCAL STUDIOS. OUTCOME MEASURES WERE ASSESSED AT BASELINE (WEEK 0) AND COMPLETION (WEEK 17). RESULTS: SIXTY-THREE ADULTS (37.2 +/- 10.8 YEARS, 79% WOMEN) WERE INCLUDED IN THE INTENTION-TO-TREAT ANALYSIS. THE EXPERIMENTAL GROUP ATTENDED 27 +/- 18 CLASSES. ANALYSES OF COVARIANCE REVEALED NO SIGNIFICANT CHANGE IN THE HIGH-FREQUENCY COMPONENT OF HRV (P = 0.912, PARTIAL ETA (2) = 0.000) OR IN ANY SECONDARY OUTCOME MEASURE BETWEEN GROUPS OVER TIME. HOWEVER, REGRESSION ANALYSES REVEALED THAT HIGHER ATTENDANCE IN THE EXPERIMENTAL GROUP WAS ASSOCIATED WITH SIGNIFICANT REDUCTIONS IN DIASTOLIC BLOOD PRESSURE (P = 0.039; PARTIAL ETA (2) = 0.154), BODY FAT PERCENTAGE (P = 0.001, PARTIAL ETA (2) = 0.379), FAT MASS (P = 0.003, PARTIAL ETA (2) = 0.294) AND BODY MASS INDEX (P = 0.05, PARTIAL ETA (2) = 0.139). CONCLUSIONS: A 16-WEEK BIKRAM YOGA PROGRAM DID NOT INCREASE THE HIGH FREQUENCY POWER COMPONENT OF HRV OR ANY OTHER CVD RISK FACTORS INVESTIGATED. AS REVEALED BY POST HOC ANALYSES, LOW ADHERENCE LIKELY CONTRIBUTED TO THE NULL EFFECTS. FUTURE STUDIES ARE REQUIRED TO ADDRESS BARRIERS TO ADHERENCE TO BETTER ELUCIDATE THE DOSE-RESPONSE EFFECTS OF BIKRAM YOGA PRACTICE AS A MEDIUM TO LOWER STRESS-RELATED CVD RISK.

11 2258  43 THE PHYSIOLOGICAL RESPONSES TO BIKRAM YOGA IN NOVICE AND EXPERIENCED PRACTITIONERS. CONTEXT: BIKRAM YOGA HAS GAINED A LARGE FOLLOWING, POSSIBLY BECAUSE OF WIDESPREAD CLAIMS BOASTING ENERGY EXPENDITURE OF UP TO 1000 CALORIES PER SESSION. HOWEVER, THESE CLAIMS ARE UNFOUNDED BECAUSE NO SCIENTIFIC STUDY HAS INVESTIGATED THE METABOLIC RESPONSE TO A COMPLETE, STANDARDIZED BIKRAM YOGA CLASS. OBJECTIVES: THIS STUDY INTENDS TO DETERMINE ENERGY EXPENDITURE, HEART RATE, AND SWEAT RATE IN NOVICE AND EXPERIENCED PRACTITIONERS FROM A STANDARDIZED BIKRAM YOGA CLASS. SETTING: DATA WERE COLLECTED IN THE ENVIRONMENTAL CHAMBER OF THE EXERCISE PHYSIOLOGY LABORATORY AT SAN DIEGO STATE UNIVERSITY IN CALIFORNIA, USA. PARTICIPANTS: MALE (N = 5) AND FEMALE (N = 19) PARTICIPANTS BETWEEN THE AGES OF 18 AND 57 Y WERE RECRUITED THROUGH FLYERS IN YOGA STUDIOS THROUGHOUT SAN DIEGO. PARTICIPANTS WERE CLASSIFIED AS EXPERIENCED OR NOVICE PRACTITIONERS, HAVING COMPLETED >/=20 OR <20 SESSIONS, RESPECTIVELY. INTERVENTIONS: PARTICIPANTS WERE GUIDED THROUGH A STANDARDIZED 90-MIN YOGA CLASS PERFORMED IN A HOT ENVIRONMENT USING BIKRAM'S STANDARD BEGINNING DIALOGUE, WHILE EXPIRED GAS WAS COLLECTED AND HEART RATE WAS RECORDED. OUTCOME MEASURES: ENERGY EXPENDITURE, CALCULATED VIA OXYGEN UPTAKE, AND HEART RATE WERE DETERMINED FOR EACH POSTURE AND TRANSITION PERIOD. IN ADDITION, SWEAT RATE AND CORE TEMPERATURE WERE RECORDED FOR EACH PARTICIPANT. RESULTS: MEAN (+/-SD) RELATIVE VO2 FOR THE ENTIRE 90-MIN SESSION WAS 9.5 +/- 1.9 ML X KG-1 X MIN-1, RANGING FROM 6.0 TO 12.9 ML X KG-1 X MIN-1. MEAN ABSOLUTE ENERGY EXPENDITURE WAS 286 +/- 72 KCALS, RANGING FROM 179 TO 478 KCALS. INDEPENDENT SAMPLE T TESTS REVEALED SIGNIFICANT DIFFERENCES (P < .05) IN RELATIVE ENERGY EXPENDITURE, HEART RATE, ENDING CORE TEMPERATURE, AND SWEAT RATE BETWEEN EXPERIENCE LEVELS. MEAN RELATIVE ENERGY EXPENDITURE WAS 3.7 +/- 0.5 KCAL/KG IN NOVICE PRACTITIONERS AND 4.7 +/- 0.8 KCAL/KG IN EXPERIENCED PRACTITIONERS. PERCENTAGE OF PREDICTED MAXIMUM HEART RATE AND SWEAT RATE WERE 72.3% +/- 10.6% AND 0.6 +/- 0.2 KG/H IN NOVICE PRACTITIONERS AND 86.4% +/- 5.2% AND 1.1 +/- 0.5 KG/H IN EXPERIENCED PARTICIPANTS. ALL POSTURES WERE CLASSIFIED AS LIGHT-TO-MODERATE INTENSITY ACCORDING TO THE AMERICAN COLLEGE OF SPORTS MEDICINE (ACSM) STANDARDS. CONCLUSIONS: BIKRAM YOGA MEETS REQUIREMENTS FOR EXERCISE OF LIGHT-TO-MODERATE INTENSITY AND, THEORETICALLY, COULD BE USED FOR WEIGHT MAINTENANCE OR WEIGHT LOSS IF PRACTICED SEVERAL TIMES PER WEEK.	2014	
                                                                                                                                                                                                                                                            
12 1871  31 RANGE OF YOGA INTENSITIES FROM SAVASANA TO SWEATING: A SYSTEMATIC REVIEW. BACKGROUND: THERE IS LIMITED RESEARCH EXAMINING THE INTENSITY OF YOGA AND INTENSITY VARIATIONS BETWEEN DIFFERENT STYLES. THE PURPOSE OF THIS REVIEW IS TO EXAMINE THE INTENSITY OF YOGA BASED ON DIFFERENT PHYSIOLOGIC RESPONSES BOTH BETWEEN DIFFERENT YOGA STYLES AND WITHIN STYLES OF YOGA. METHODS: ARTICLES WERE SEARCHED FOR ON THE PUBMED DATABASE IN EARLY 2019. INCLUSION CRITERIA WERE AS FOLLOWS: (1) WRITTEN IN ENGLISH, (2) CITE A SPECIFIC STYLE OF YOGA AND INCLUDE WHOLE YOGA SESSION, AND (3) MEASURE METABOLIC OR HEART RATE RESPONSE. RESULTS: TEN ARTICLES WERE REVIEWED; ARTICLES REPORTED OXYGEN CONSUMPTION (N = 1), HEART RATE (N = 4), OR BOTH VARIABLES (N = 5). YOGA STYLES ASSESSED INCLUDED ASHTANGA (N = 2), BIKRAM (N = 3), GENTLE (N = 1), HATHA (N = 3), IYENGAR (N = 1), POWER (N = 1), AND VINYASA (N = 1). OXYGEN CONSUMPTION COMMONLY CATEGORIZED YOGA AS A LIGHT-INTENSITY ACTIVITY, WHILE HEART RATE RESPONSES CLASSIFIED DIFFERENT YOGA INTO MULTIPLE INTENSITIES. CONCLUSION: THIS REVIEW DEMONSTRATES THAT LARGE DIFFERENCES IN INTENSITY CLASSIFICATIONS ARE OBSERVED BETWEEN DIFFERENT STYLES OF YOGA. FURTHERMORE, METABOLIC AND HEART RATE RESPONSES CAN BE VARIABLE, LEADING TO INCONSISTENT INTENSITY CLASSIFICATIONS. THIS IS LIKELY DUE TO THEIR NONLINEAR RELATIONSHIP DURING YOGA. THUS, IT IS IMPERATIVE THAT THE FIELD OF YOGA RESEARCH WORKS TOGETHER TO CREATE A STANDARD FOR REPORTING YOGA.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
13 1235  33 FEASIBILITY AND SAFETY OF INTRADIALYSIS YOGA AND EDUCATION IN MAINTENANCE HEMODIALYSIS PATIENTS. OBJECTIVE: PATIENTS WITH END-STAGE RENAL DISEASE ON MAINTENANCE HEMODIALYSIS ARE MUCH MORE SEDENTARY THAN HEALTHY INDIVIDUALS. THE PURPOSE OF THIS STUDY WAS TO ASSESS THE FEASIBILITY AND SAFETY OF A 12-WEEK INTRADIALYSIS YOGA INTERVENTION VERSUS A KIDNEY EDUCATION INTERVENTION ON THE PROMOTION OF PHYSICAL ACTIVITY. DESIGN AND METHODS: WE RANDOMIZED PARTICIPANTS BY DIALYSIS SHIFT TO EITHER 12-WEEK INTRADIALYSIS YOGA OR AN EDUCATIONAL INTERVENTION. INTRADIALYSIS YOGA WAS PROVIDED BY YOGA TEACHERS TO PARTICIPANTS WHILE RECEIVING HEMODIALYSIS. PARTICIPANTS RECEIVING THE 12-WEEK EDUCATIONAL INTERVENTION RECEIVED A MODIFICATION OF A PREVIOUSLY DEVELOPED COMPREHENSIVE EDUCATIONAL PROGRAM FOR PATIENTS WITH KIDNEY DISEASE (KIDNEY SCHOOL). THE PRIMARY OUTCOME FOR THIS STUDY WAS FEASIBILITY BASED ON RECRUITMENT AND ADHERENCE TO THE INTERVENTIONS AND SAFETY OF INTRADIALYSIS YOGA. SECONDARY OUTCOMES WERE TO DETERMINE THE FEASIBILITY OF ADMINISTERING QUESTIONNAIRES AT BASELINE AND 12 WEEKS INCLUDING THE KIDNEY DISEASE-RELATED QUALITY OF LIFE-36. RESULTS: AMONG 56 ELIGIBLE PATIENTS WHO APPROACHED FOR THE STUDY, 31 (55%) WERE INTERESTED AND CONSENTED TO PARTICIPATION, WITH 18 ASSIGNED TO INTRADIALYSIS YOGA AND 13 TO THE EDUCATIONAL PROGRAM. A TOTAL OF 5 PARTICIPANTS WITHDREW FROM THE PILOT STUDY, ALL FROM THE INTRADIALYSIS YOGA GROUP. TWO OF THESE PARTICIPANTS REPORTED NO FURTHER INTEREST IN PARTICIPATION. THREE WITHDRAWN PARTICIPANTS SWITCHED DIALYSIS TIMES AND THEREFORE COULD NO LONGER RECEIVE INTRADIALYSIS YOGA. AS A RESULT, 13 OF 18 (72%) AND 13 OF 13 (100%) PARTICIPANTS COMPLETED 12-WEEK INTRADIALYSIS YOGA AND EDUCATIONAL PROGRAMS, RESPECTIVELY. THERE WERE NO ADVERSE EVENTS RELATED TO INTRADIALYSIS YOGA. INTERVENTION PARTICIPANTS PRACTICED YOGA FOR A MEDIAN OF 21 SESSIONS (70% PARTICIPATION FREQUENCY), WITH 60% OF PARTICIPANTS PRACTICING AT LEAST 2 TIMES A WEEK. PARTICIPANTS IN THE EDUCATIONAL PROGRAM COMPLETED A MEDIAN OF 30 SESSIONS (83% PARTICIPATION FREQUENCY). OF PARTICIPANTS WHO COMPLETED THE STUDY (N = 26), BASELINE AND 12-WEEK QUESTIONNAIRES WERE OBTAINED FROM 85%. CONCLUSIONS: OUR PILOT STUDY OF 12-WEEK INTRADIALYSIS YOGA AND 12-WEEK EDUCATIONAL INTERVENTION REACHED RECRUITMENT GOALS BUT WITH LESS THAN TARGETED COMPLETION AND ADHERENCE TO INTERVENTION RATES. THIS STUDY PROVIDED VALUABLE FEASIBILITY DATA TO INCREASE FOLLOW-UP AND ADHERENCE FOR FUTURE CLINICAL TRIALS TO COMPARE EFFICACY.	2015	
                                                                                                                                                                                                                           
14  944  27 EFFECTS OF A 12-WEEK HATHA YOGA INTERVENTION ON METABOLIC RISK AND QUALITY OF LIFE IN HONG KONG CHINESE ADULTS WITH AND WITHOUT METABOLIC SYNDROME. OBJECTIVE: TO DETERMINE THE EFFICACY OF A 12-WEEK HATHA YOGA INTERVENTION TO IMPROVE METABOLIC RISK PROFILES AND HEALTH-RELATED QUALITY OF LIFE (HRQOL) IN CHINESE ADULTS WITH AND WITHOUT METABOLIC SYNDROME (METS). METHODS: WE CONDUCTED A CONTROLLED TRIAL WITHIN AN UNIVERSITY-AFFILIATED HOSPITAL. 173 CHINESE MEN AND WOMEN AGED 18 OR ABOVE WERE ASSIGNED TO EITHER THE YOGA INTERVENTION GROUP (N = 87) OR THE CONTROL GROUP (N = 86). PRIMARY OUTCOMES INCLUDED 12-WEEK CHANGE IN METABOLIC RISK FACTORS AND METS Z SCORE. SECONDARY OUTCOME WAS HRQOL (MEDICAL OUTCOMES SHORT FORM SURVEY AT 12 WEEKS). RESULTS: THE MEAN AGE OF PARTICIPANTS WAS 52.0 (SD 7.4, RANGE 31-71) YEARS. ANALYSIS INVOLVING THE ENTIRE STUDY POPULATION REVEALED THAT THE YOGA GROUP ACHIEVED GREATER DECLINE IN WAIST CIRCUMFERENCE (P<0.001), FASTING GLUCOSE (P<0.01), TRIGLYCERIDES (P<0.05), AND METS Z SCORE (P<0.01). YOGA TRAINING ALSO IMPROVED GENERAL HEALTH PERCEPTIONS (P<0.01), PHYSICAL COMPONENT SCORE (P<0.01), AND SOCIAL FUNCTIONING (P<0.01) DOMAINS SCORE OF HRQOL. HOWEVER, NO SIGNIFICANT DIFFERENCES BETWEEN GROUPS WERE OBSERVED IN THE MEAN CHANGE OF SYSTOLIC/DIASTOLIC BLOOD PRESSURES OR HIGH-DENSITY LIPID PROTEIN CHOLESTEROL (ALL P>0.05). THERE WERE NO SIGNIFICANT DIFFERENCES IN THE INTERVENTION EFFECTS ON WAIST CIRCUMFERENCE AND METS Z SCORE BETWEEN THE METS SUBGROUPS (BOTH P>0.05). CONCLUSION: A 12-WEEK HATHA YOGA INTERVENTION IMPROVES METABOLIC RISK PROFILES AND HRQOL IN CHINESE ADULTS WITH AND WITHOUT METS.

15  675  28 EFFECT OF A SIX-MONTH YOGA EXERCISE INTERVENTION ON FITNESS OUTCOMES FOR BREAST CANCER SURVIVORS. YOGA-BASED EXERCISE HAS PROVEN TO BE BENEFICIAL FOR PRACTITIONERS, INCLUDING CANCER SURVIVORS. THIS STUDY REPORTS ON THE IMPROVEMENTS IN PHYSICAL FITNESS FOR 20 BREAST CANCER SURVIVORS WHO PARTICIPATED IN A SIX-MONTH YOGA-BASED EXERCISE PROGRAM (YE). RESULTS ARE COMPARED TO A COMPREHENSIVE EXERCISE (CE) PROGRAM GROUP AND A COMPARISON (C) EXERCISE GROUP WHO CHOSE THEIR OWN EXERCISES. "PRE" AND "POST" FITNESS ASSESSMENTS INCLUDED MEASURES OF ANTHROPOMETRICS, CARDIORESPIRATORY CAPACITY, STRENGTH AND FLEXIBILITY. DESCRIPTIVE STATISTICS, EFFECT SIZE (D), DEPENDENT SAMPLE 'T' TESTS FOR ALL OUTCOME MEASURES WERE CALCULATED FOR THE YE GROUP. SIGNIFICANT IMPROVEMENTS INCLUDED: DECREASED % BODY FAT (-3.00%, D = -0.44, P < 0.001); INCREASED SIT TO STAND LEG STRENGTH REPETITIONS (2.05, D = 0.48, P = 0.003); FORWARD REACH (3.59 CM, D = 0.61, P = 0.01); AND RIGHT ARM SAGITTAL RANGE OF MOTION (6.50 DEGREES , D = 0.92, P = 0.05). TO COMPARE YE OUTCOMES WITH THE OTHER TWO GROUPS, A ONE-WAY ANALYSIS OF VARIANCE (ANOVA) WAS USED. YE PARTICIPANTS SIGNIFICANTLY OUTPERFORMED C PARTICIPANTS ON "FORWARD REACH" (3.59 CM GAINED VERSUS -2.44 CM LOST), (P = 0.009) AND OUTPERFORMED CE PARTICIPANTS (3.59 CM GAINED VERSUS 1.35 CM GAINED), BUT NOT STATISTICALLY SIGNIFICANT. OUR RESULTS SUPPORT YOGA-BASED EXERCISE MODIFIED FOR BREAST CANCER SURVIVORS AS SAFE AND EFFECTIVE.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
16 2193  36 THE EFFECTS OF YOGA TRAINING AND A SINGLE BOUT OF YOGA ON DELAYED ONSET MUSCLE SORENESS IN THE LOWER EXTREMITY. THE PURPOSE OF THIS STUDY WAS TO DETERMINE THE EFFECTS OF YOGA TRAINING AND A SINGLE BOUT OF YOGA ON THE INTENSITY OF DELAYED ONSET MUSCLE SORENESS (DOMS). 24 YOGA-TRAINED (YT; N = 12) AND NON-YOGA-TRAINED (CON; N = 12), MATCHED WOMEN VOLUNTEERS WERE ADMINISTERED A DOMS-INDUCING BENCH-STEPPING EXERCISE. MUSCLE SORENESS WAS ASSESSED AT BASELINE, 24, 48, 72, 96, AND 120 HOURS AFTER BENCH-STEPPING USING A VISUAL ANALOG SCALE (VAS). GROUPS WERE ALSO COMPARED ON BODY AWARENESS (BA), FLEXIBILITY USING THE SIT-AND-REACH TEST (SR), AND PERCEIVED EXERTION (RPE). STATISTICAL SIGNIFICANCE WAS ACCEPTED AT P </= 0.05. A 2 X 2 MIXED FACTORIAL ANOVA WITH REPEATED MEASURES AT 24 AND 48 HOURS REVEALED A SIGNIFICANT (P < 0.05) GROUP MAIN EFFECT WITH VAS SCORES GREATER FOR CON THAN YT. PAIRED T-TESTS REVEALED THAT IN YT, VAS SCORES WERE HIGHER BEFORE YOGA CLASS THAN AFTER YOGA CLASS AT 24 HOURS (21.4 [+/- 6.9] MM VS. 11.1 [+/- 4.1] MM; P = 0.02). THE SR WAS GREATER IN YT THAN IN CON (65.0 [+/- 7.9] CM VS. 33.3 [+/- 7.0] CM; P < 0.01); HOWEVER, NO DIFFERENCES WERE FOUND BETWEEN YOGA AND CONTROL IN BA (94.0 [+/- 4.4] UNITS VS. 83.8 [+/- 3.7] UNITS; P = 0.21) OR IN RPE AT 5-MINUTE INTERVALS (2.9 [+/- 0.3], 5.3 [+/- 0.8], 5.8 [+/- 0.9], AND 5.2 [+/- 0.8] VS. 2.5 [+/- 0.3], 4.0 [+/- 0.5], 4.2 [+/- 0.3], AND 4.9 [+/- 0.4]. YOGA TRAINING AND A SINGLE BOUT OF YOGA APPEAR TO ATTENUATE PEAK MUSCLE SORENESS IN WOMEN FOLLOWING A BOUT OF ECCENTRIC EXERCISE. THESE FINDINGS HAVE SIGNIFICANT IMPLICATIONS FOR COACHES, ATHLETES, AND THE EXERCISING PUBLIC WHO MAY WANT TO IMPLEMENT YOGA TRAINING AS A PRESEASON REGIMEN OR SUPPLEMENTAL ACTIVITY TO LESSEN THE SYMPTOMS ASSOCIATED WITH MUSCLE SORENESS.	2004	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
17 1344  24 HYDRATION AND HOT YOGA: ENCOURAGEMENT, BEHAVIORS, AND OUTCOMES. CONTEXT: CURRENTLY, THE LITERATURE ON HOT YOGA IS LACKING, AND THERE IS STILL MUCH TO UNDERSTAND REGARDING THE SAFETY OF THESE PRACTICES. HOWEVER, ONE POINT OF SAFETY OFTEN EMPHASIZED IS HYDRATION DURING THE PRACTICE OF HOT YOGA. AIM: THE AIM OF THIS STUDY WAS TO EXAMINE HYDRATION ENCOURAGEMENT BY HOT YOGA INSTRUCTORS AND HYDRATION BEHAVIORS AND RELATED OUTCOMES BY HOT YOGA PARTICIPANTS. METHODS: A CROSS-SECTIONAL STUDY (N = 700) COLLECTED SELF-REPORT DATA ON DEMOGRAPHICS, TYPES AND FREQUENCY OF YOGA PRACTICED, HYDRATION BEHAVIORS, AND SELF-REPORT MEASURES OF ADVERSE OUTCOMES EXPERIENCED BY PARTICIPANTS DURING HOT YOGA. ASSOCIATIONS BETWEEN HYDRATION ENCOURAGEMENT, PROTECTIVE BEHAVIORS, AND ADVERSE OUTCOMES WERE ANALYZED THROUGH CHI-SQUARE TESTS. RESULTS: EVERY PROTECTIVE HYDRATION BEHAVIOR WAS SIGNIFICANTLY ASSOCIATED WITH INSTRUCTOR ENCOURAGEMENT (P < 0.05). HYDRATION BEFORE OR DURING HOT YOGA PARTICIPATION WAS ASSOCIATED WITH A LOWER OCCURRENCE OF DEHYDRATION SYMPTOMS (P < 0.05). CONCLUSIONS: HOT YOGA INSTRUCTORS HOLD A KEY ROLE IN ENCOURAGING HYDRATION AND STUDENT SAFETY OUTCOMES.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
18  687  38 EFFECT OF AN OFFICE WORKSITE-BASED YOGA PROGRAM ON HEART RATE VARIABILITY: OUTCOMES OF A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: CHRONIC WORK-RELATED STRESS IS AN INDEPENDENT RISK FACTOR FOR CARDIOMETABOLIC DISEASES AND ASSOCIATED MORTALITY, PARTICULARLY WHEN COMPOUNDED BY A SEDENTARY WORK ENVIRONMENT. THE PURPOSE OF THIS STUDY WAS TO DETERMINE IF AN OFFICE WORKSITE-BASED HATHA YOGA PROGRAM COULD IMPROVE PHYSIOLOGICAL STRESS, EVALUATED VIA HEART RATE VARIABILITY (HRV), AND ASSOCIATED HEALTH-RELATED OUTCOMES IN A COHORT OF OFFICE WORKERS. METHODS: THIRTY-SEVEN ADULTS EMPLOYED IN UNIVERSITY-BASED OFFICE POSITIONS WERE RANDOMIZED UPON THE COMPLETION OF BASELINE TESTING TO AN EXPERIMENTAL OR CONTROL GROUP. THE EXPERIMENTAL GROUP COMPLETED A 10-WEEK YOGA PROGRAM PRESCRIBED THREE SESSIONS PER WEEK DURING LUNCH HOUR (50 MIN PER SESSION). AN EXPERIENCED INSTRUCTOR LED THE SESSIONS, WHICH EMPHASIZED ASANAS (POSTURES) AND VINYASA (EXERCISES). THE PRIMARY OUTCOME WAS THE HIGH FREQUENCY (HF) POWER COMPONENT OF HRV. SECONDARY OUTCOMES INCLUDED ADDITIONAL HRV PARAMETERS, MUSCULOSKELETAL FITNESS (I.E. PUSH-UP, SIDE-BRIDGE, AND SIT & REACH TESTS) AND PSYCHOLOGICAL INDICES (I.E. STATE AND TRAIT ANXIETY, QUALITY OF LIFE AND JOB SATISFACTION). RESULTS: ALL MEASURES OF HRV FAILED TO CHANGE IN THE EXPERIMENTAL GROUP VERSUS THE CONTROL GROUP, EXCEPT THAT THE EXPERIMENTAL GROUP SIGNIFICANTLY INCREASED LF:HF (P = 0.04) AND REDUCED PNN50 (P = 0.04) VERSUS CONTROL, CONTRARY TO OUR HYPOTHESES. FLEXIBILITY, EVALUATED VIA SIT & REACH TEST INCREASED IN THE EXPERIMENTAL GROUP VERSUS THE CONTROL GROUP (P < 0.001). NO OTHER ADAPTATIONS WERE NOTED. POST HOC ANALYSIS COMPARING PARTICIPANTS WHO COMPLETED >/=70% OF YOGA SESSIONS (N = 11) TO CONTROL (N = 19) YIELDED THE SAME FINDINGS, EXCEPT THAT THE HIGH ADHERERS ALSO REDUCED STATE ANXIETY (P = 0.02) AND RMSSD (P = 0.05), AND TENDED TO IMPROVE THE PUSH-UP TEST (P = 0.07) VERSUS CONTROL. CONCLUSIONS: A 10-WEEK HATHA YOGA INTERVENTION DELIVERED AT THE OFFICE WORKSITE DURING LUNCH HOUR DID NOT IMPROVE HF POWER OR OTHER HRV PARAMETERS. HOWEVER, IMPROVEMENTS IN FLEXIBILITY, STATE ANXIETY AND MUSCULOSKELETAL FITNESS WERE NOTED WITH HIGH ADHERENCE. FUTURE INVESTIGATIONS SHOULD INCORPORATE STRATEGIES TO PROMOTE ADHERENCE, INVOLVE MORE FREQUENT AND LONGER DURATIONS OF YOGA TRAINING, AND ENROL COHORTS WHO SUFFER FROM HIGHER LEVELS OF WORK-RELATED STRESS.

19 1451  29 INFLUENCE OF INTENSIVE YOGA TRAINING ON PHYSIOLOGICAL CHANGES IN 6 ADULT WOMEN: A CASE REPORT. THE SHORT-TERM EFFECTS OF 4 WEEKS OF INTENSIVE YOGA PRACTICE ON PHYSIOLOGICAL RESPONSES IN SIX HEALTHY ADULT FEMALE VOLUNTEERS WERE MEASURED USING THE MAXIMAL EXERCISE TREADMILL TEST. YOGA PRACTICE INVOLVED DAILY MORNING AND EVENING SESSIONS OF 90 MINUTES EACH. PRE- AND POST-YOGA EXERCISE PERFORMANCE WAS COMPARED. MAXIMAL WORK OUTPUT (WMAX) FOR THE GROUP INCREASED BY 21%, WITH A SIGNIFICANTLY REDUCED LEVEL OF OXYGEN CONSUMPTION PER UNIT WORK BUT WITHOUT A CONCOMITANT SIGNIFICANT CHANGE IN HEART RATE. AFTER INTENSIVE YOGA TRAINING, AT 154 WMIN(-1) (CORRESPONDING TO WMAX OF THE PRE-YOGA MAXIMAL EXERCISE TEST) PARTICIPANTS COULD EXERCISE MORE COMFORTABLY, WITH A SIGNIFICANTLY LOWER HEART RATE (P < 0.05), REDUCED MINUTE VENTILATION (P < 0.05), REDUCED OXYGEN CONSUMPTION PER UNIT WORK (P < 0.05), AND A SIGNIFICANTLY LOWER RESPIRATORY QUOTIENT (P < 0.05). THE IMPLICATIONS FOR THE EFFECT OF INTENSIVE YOGA ON CARDIORESPIRATORY EFFICIENCY ARE DISCUSSED, WITH THE SUGGESTION THAT YOGA HAS SOME TRANSPARENTLY DIFFERENT QUANTIFIABLE PHYSIOLOGICAL EFFECTS TO OTHER EXERCISES.	1997	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
20  410  31 BLOOD LIPIDS AND ANTHROPOMETRIC PARAMETERS IN HEALTHY SUBJECTS PRACTICING YOGA OR RESISTANCE TRAINING IN LEISURE TIME. WHAT MATTERS: TYPE OR INTENSITY OF PHYSICAL ACTIVITY? AIM: THE AIM OF THE PRESENT STUDY WAS TO ASSESS EFFECTS OF YOGA AND RESISTANCE TRAININGS ON BLOOD LIPIDS AND ANTHROPOMETRIC PARAMETERS IN PEOPLE WITHOUT CARDIOVASCULAR DISEASES. MATERIALS AND METHODS: CROSS-SECTIONAL STUDY, WHICH INCLUDED 167 SUBJECTS, WAS CONDUCTED. SUBJECTS REGULARLY PRACTICING YOGA OR RESISTANCE TRAINING NOT LESS THAN 2 TIMES A WEEK FOR A PERIOD MORE THAN ONE YEAR WERE INCLUDED IN THE STUDY. YOGA TRAININGS WERE DEFINED AS YOGA ASANAS AND RESISTANCE TRAININGS WERE DEFINED AS ANY EXERCISE THAT CAUSES THE MUSCLES TO CONTRACT AGAINST AN EXTERNAL RESISTANCE. ANTHROPOMETRIC PARAMETERS, BLOOD LIPIDS AND GLUCOSE, URIC ACID WERE ASSESSED. WE USED INTERNATIONAL QUESTIONNAIRE ON LONG PHYSICAL ACTIVITY TO ASSESS PHYSICAL ACTIVITY AND SEDENTARY TIME. SPSS 17.0 WAS USED TO PERFORM STATISTICAL ANALYSIS. RESULTS: THERE WERE NO SIGNIFICANT DIFFERENCES BETWEEN "YOGA TRAINING" AND "RESISTANCE TRAINING" GROUPS IN GENERAL PHYSICAL ACTIVITY, MODERATE PHYSICAL ACTIVITY AND SITTING TIME IN THE WHOLE GROUP. HDL-CHOLESTEROL WAS SIGNIFICANTLY HIGHER IN "YOGA TRAINING" COMPARED TO "RESISTANCE TRAINING" GROUP AND CONTROL GROUP (1,65+/-0,37 MMOL/L; 1,43+/-0,21 MMOL/L AND 1,34+/-0,22, PYOGA-RESISTANCE TRAINING=0,001; PYOGA-CONTROL=0,0001; PRESISTANCE TRAINING-CONTROL= P2-3=0,037). LDL CHOLESTEROL WAS THE LOWEST IN SUBJECTS THAT HAD THE HIGHEST LEVEL OF VIGOROUS PHYSICAL ACTIVITY. CONCLUSIONS: PEOPLE PRACTICING YOGA AND RESISTANCE TRAINING HAD MORE FAVORABLE BLOOD LIPID PROFILE AND ANTHROPOMETRIC PARAMETERS THAN CONTROL GROUP. "YOGA TRAINING" HAD MORE PRONOUNCED POSITIVE EFFECT ON HDL CHOLESTEROL. LEVEL OF LDL CHOLESTEROL WAS MORE LIKELY TO BE ASSOCIATED WITH INTENSITY OF PHYSICAL ACTIVITY THAN WITH TYPE OF PHYSICAL ACTIVITY.	2021
