1   81 90 A MATHEMATICAL MODEL OF EFFECTS ON SPECIFIC JOINTS DURING PRACTICE OF THE SUN SALUTATION--A SEQUENCE OF YOGA POSTURES. THE 'SUN SALUTATION' CONSISTS OF A SEQUENCE OF TEN YOGA POSTURES, EACH POSTURE COUNTERACTING THE PRECEDING ONE PRODUCING A BALANCE BETWEEN FLEXION AND EXTENSION, PERFORMED WITH SYNCHRONIZED BREATHING AND AEROBIC ACTIVITY. AS THIS SEQUENCE IS OFTEN PERFORMED AND RECOMMENDED BY MANY YOGA PRACTITIONERS, THERE IS A NEED FOR THE DEVELOPMENT OF A BIOMECHANICAL MODEL TO SUPPORT ITS REPORTED CLINICAL BENEFITS. THIS REQUIRES A DETAILED KNOWLEDGE OF THE NATURE OF THE FORCES AND MOMENTS AT THE VARIOUS JOINTS INVOLVED. A SIMPLE MATHEMATICAL MODEL BASED ON RIGID BODY MECHANICS IS DEVELOPED FOR EACH OF THE SUN SALUTATION POSTURES. DYNAMIC MOMENTS WITH HIGH MAGNITUDES AND RATES, APPLIED WITH UNUSUAL DISTRIBUTION PATTERNS, OPTIMAL FOR OSTEOGENESIS, ARE FOUND TO OCCUR. ALSO, THE JOINTS ARE SUBJECTED TO SUBMAXIMAL LOADINGS THUS ENSURING THAT NONE OF THE JOINTS ARE OVERSTRESSED.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
2  642 26 DOES PRACTICING HATHA YOGA SATISFY RECOMMENDATIONS FOR INTENSITY OF PHYSICAL ACTIVITY WHICH IMPROVES AND MAINTAINS HEALTH AND CARDIOVASCULAR FITNESS? BACKGROUND: LITTLE IS KNOWN ABOUT THE METABOLIC AND HEART RATE RESPONSES TO A TYPICAL HATHA YOGA SESSION. THE PURPOSES OF THIS STUDY WERE 1) TO DETERMINE WHETHER A TYPICAL YOGA PRACTICE USING VARIOUS POSTURES MEETS THE CURRENT RECOMMENDATIONS FOR LEVELS OF PHYSICAL ACTIVITY REQUIRED TO IMPROVE AND MAINTAIN HEALTH AND CARDIOVASCULAR FITNESS; 2) TO DETERMINE THE RELIABILITY OF METABOLIC COSTS OF YOGA ACROSS SESSIONS; 3) TO COMPARE THE METABOLIC COSTS OF YOGA PRACTICE TO THOSE OF TREADMILL WALKING. METHODS: IN THIS OBSERVATIONAL STUDY, 20 INTERMEDIATE-TO-ADVANCED LEVEL YOGA PRACTITIONERS, AGE 31.4 +/- 8.3 YEARS, PERFORMED AN EXERCISE ROUTINE INSIDE A HUMAN RESPIRATORY CHAMBER (INDIRECT CALORIMETER) WHILE WEARING HEART RATE MONITORS. THE EXERCISE ROUTINE CONSISTED OF 30 MINUTES OF SITTING, 56 MINUTES OF BEGINNER-LEVEL HATHA YOGA ADMINISTERED BY VIDEO, AND 10 MINUTES OF TREADMILL WALKING AT 3.2 AND 4.8 KPH EACH. MEASURES WERE MEAN OXYGEN CONSUMPTION (VO2), HEART RATE (HR), PERCENTAGE PREDICTED MAXIMAL HEART RATE (%MHR), METABOLIC EQUIVALENTS (METS), AND ENERGY EXPENDITURE (KCAL). SEVEN SUBJECTS REPEATED THE PROTOCOL SO THAT MEASUREMENT RELIABILITY COULD BE ESTABLISHED. RESULTS: MEAN VALUES ACROSS THE ENTIRE YOGA SESSION FOR VO2, HR, %MHR, METS, AND ENERGY/MIN WERE 0.6 L/KG/MIN; 93.2 BEATS/MIN; 49.4%; 2.5; AND 3.2 KCAL/MIN; RESPECTIVELY. RESULTS OF THE ICCS (2,1) FOR MEAN VALUES ACROSS THE ENTIRE YOGA SESSION FOR KCAL, METS, AND %MHR WERE 0.979 AND 0.973, AND 0.865, RESPECTIVELY. CONCLUSION: METABOLIC COSTS OF YOGA AVERAGED ACROSS THE ENTIRE SESSION REPRESENT LOW LEVELS OF PHYSICAL ACTIVITY, ARE SIMILAR TO WALKING ON A TREADMILL AT 3.2 KPH, AND DO NOT MEET RECOMMENDATIONS FOR LEVELS OF PHYSICAL ACTIVITY FOR IMPROVING OR MAINTAINING HEALTH OR CARDIOVASCULAR FITNESS. YOGA PRACTICE INCORPORATING SUN SALUTATION POSTURES EXCEEDING THE MINIMUM BOUT OF 10 MINUTES MAY CONTRIBUTE SOME PORTION OF SUFFICIENTLY INTENSE PHYSICAL ACTIVITY TO IMPROVE CARDIO-RESPIRATORY FITNESS IN UNFIT OR SEDENTARY INDIVIDUALS. THE MEASUREMENT OF ENERGY EXPENDITURE ACROSS YOGA SESSIONS IS HIGHLY RELIABLE.	2007	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
3  229 21 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
4  613 24 DEVELOPMENT OF A YOGA PROGRAM FOR TYPE-2 DIABETES PREVENTION (YOGA-DP) AMONG HIGH-RISK PEOPLE IN INDIA. INTRODUCTION: MANY INDIANS ARE AT HIGH-RISK OF TYPE-2 DIABETES MELLITUS (T2DM). YOGA IS AN ANCIENT INDIAN MIND-BODY DISCIPLINE, THAT HAS BEEN ASSOCIATED WITH IMPROVED GLUCOSE LEVELS AND CAN HELP TO PREVENT T2DM. THE STUDY AIMED TO SYSTEMATICALLY DEVELOP A YOGA PROGRAM FOR T2DM PREVENTION (YOGA-DP) AMONG HIGH-RISK PEOPLE IN INDIA USING A COMPLEX INTERVENTION DEVELOPMENT APPROACH. MATERIALS AND METHODS: AS PART OF THE INTERVENTION, WE DEVELOPED A BOOKLET AND A HIGH-DEFINITION VIDEO FOR PARTICIPANTS AND A MANUAL FOR YOGA-DP INSTRUCTORS. A SYSTEMATIC ITERATIVE PROCESS WAS FOLLOWED TO DEVELOP THE INTERVENTION AND INCLUDED FIVE STEPS: (I) A SYSTEMATIC REVIEW OF THE LITERATURE TO GENERATE A LIST OF YOGIC PRACTICES THAT IMPROVES BLOOD GLUCOSE LEVELS AMONG ADULTS AT HIGH-RISK OF OR WITH T2DM, (II) VALIDATION OF IDENTIFIED YOGIC PRACTICES BY YOGA EXPERTS, (III) DEVELOPMENT OF THE INTERVENTION, (IV) CONSULTATION WITH YOGA, EXERCISE, PHYSICAL ACTIVITY, DIET, BEHAVIOR CHANGE, AND/OR DIABETES EXPERTS ABOUT THE INTERVENTION, AND (V) PRETEST THE INTERVENTION AMONG YOGA PRACTITIONERS AND LAY PEOPLE (THOSE AT RISK OF T2DM AND HAD NOT PRACTICED YOGA BEFORE) IN INDIA. RESULTS: YOGA-DP IS A STRUCTURED LIFESTYLE EDUCATION AND EXERCISE PROGRAM, PROVIDED OVER A PERIOD OF 24 WEEKS. THE EXERCISE PART IS BASED ON YOGA AND INCLUDES SHITHILIKARANA VYAYAMA (LOOSENING EXERCISES), SURYA NAMASKAR (SUN SALUTATION EXERCISES), ASANA (YOGIC POSES), PRANAYAMA (BREATHING PRACTICES), AND DHYANA (MEDITATION) AND RELAXATION PRACTICES. ONCE PARTICIPANTS COMPLETE THE PROGRAM, THEY ARE STRONGLY ENCOURAGED TO MAINTAIN A HEALTHY LIFESTYLE IN THE LONG-TERM. CONCLUSIONS: WE SYSTEMATICALLY DEVELOPED A NOVEL YOGA PROGRAM FOR T2DM PREVENTION (YOGA-DP) AMONG HIGH-RISK PEOPLE IN INDIA. A MULTI-CENTER FEASIBILITY RANDOMIZED CONTROLLED TRIAL IS IN PROGRESS IN INDIA.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
5  626 23 DIFFERENCE IN MUSCLE ACTIVATION PATTERNS DURING HIGH-SPEED VERSUS STANDARD-SPEED YOGA: A RANDOMIZED SEQUENCE CROSSOVER STUDY. OBJECTIVES: TO COMPARE THE DIFFERENCE IN MUSCLE ACTIVATION BETWEEN HIGH-SPEED YOGA AND STANDARD-SPEED YOGA AND TO COMPARE MUSCLE ACTIVATION OF THE TRANSITIONS BETWEEN POSES AND THE HELD PHASES OF A YOGA POSE. DESIGN: RANDOMIZED SEQUENCE CROSSOVER TRIAL SETTING: A LABORATORY OF NEUROMUSCULAR RESEARCH AND ACTIVE AGING INTERVENTIONS: EIGHT MINUTES OF CONTINUOUS SUN SALUTATION B WAS PERFORMED, AT A HIGH SPEED VERSUS A STANDARD-SPEED, SEPARATELY. ELECTROMYOGRAPHY WAS USED TO QUANTIFY NORMALIZED MUSCLE ACTIVATION PATTERNS OF EIGHT UPPER AND LOWER BODY MUSCLES (PECTORALIS MAJOR, MEDIAL DELTOIDS, LATERAL HEAD OF THE TRICEPS, MIDDLE FIBERS OF THE TRAPEZIUS, VASTUS MEDIALIS, MEDIAL GASTROCNEMIUS, THORACIC EXTENSOR SPINAE, AND EXTERNAL OBLIQUES) DURING THE HIGH-SPEED AND STANDARD-SPEED YOGA PROTOCOLS. MAIN OUTCOME MEASURES: DIFFERENCE IN NORMALIZED MUSCLE ACTIVATION BETWEEN HIGH-SPEED YOGA AND STANDARD-SPEED YOGA. RESULTS: NORMALIZED MUSCLE ACTIVITY SIGNALS WERE SIGNIFICANTLY HIGHER IN ALL EIGHT MUSCLES DURING THE TRANSITION PHASES OF POSES COMPARED TO THE HELD PHASES (P<0.01). THERE WAS NO SIGNIFICANT INTERACTION BETWEEN SPEEDXPHASE; HOWEVER, GREATER NORMALIZED MUSCLE ACTIVITY WAS SEEN FOR HIGHSPEED YOGA ACROSS THE ENTIRE SESSION. CONCLUSIONS: OUR RESULTS SHOW THAT TRANSITIONS FROM ONE HELD PHASE OF A POSE TO ANOTHER PRODUCES HIGHER NORMALIZED MUSCLE ACTIVITY THAN THE HELD PHASES OF THE POSES AND THAT OVERALL ACTIVITY IS GREATER DURING HIGHSPEED YOGA THAN STANDARD-SPEED YOGA. THEREFORE, THE TRANSITION SPEED AND ASSOCIATED NUMBER OF POSES SHOULD BE CONSIDERED WHEN TARGETING SPECIFIC IMPROVEMENTS IN PERFORMANCE.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
6 1147 22 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
7 2764 24 YOGA PROGRAMME FOR TYPE-2 DIABETES PREVENTION (YOGA-DP) AMONG HIGH RISK PEOPLE IN INDIA: A MULTICENTRE FEASIBILITY RANDOMISED CONTROLLED TRIAL PROTOCOL. INTRODUCTION: A HUGE POPULATION IN INDIA IS AT HIGH RISK OF TYPE-2 DIABETES (T2DM). PHYSICAL ACTIVITY AND A HEALTHY DIET (HEALTHY LIFESTYLE) IMPROVE BLOOD GLUCOSE LEVELS IN PEOPLE AT HIGH RISK OF T2DM. HOWEVER, AN UNHEALTHY LIFESTYLE IS COMMON AMONG INDIANS. YOGA COVERS PHYSICAL ACTIVITY AND A HEALTHY DIET AND CAN HELP TO PREVENT T2DM. THE RESEARCH QUESTION TO BE ADDRESSED BY THE MAIN RANDOMISED CONTROLLED TRIAL (RCT) IS WHETHER A YOGA PROGRAMME FOR T2DM PREVENTION (YOGA-DP) IS EFFECTIVE IN PREVENTING T2DM AMONG HIGH RISK PEOPLE IN INDIA AS COMPARED WITH ENHANCED STANDARD CARE. IN THIS CURRENT STUDY, WE ARE DETERMINING THE FEASIBILITY OF UNDERTAKING THE MAIN RCT. INTERVENTION: YOGA-DP IS A STRUCTURED LIFESTYLE EDUCATION AND EXERCISE PROGRAMME. THE EXERCISE PART IS BASED ON YOGA AND INCLUDES SHITHILIKARANA VYAYAMA (LOOSENING EXERCISES), SURYA NAMASKAR (SUN SALUTATION EXERCISES), ASANA (YOGIC POSES), PRANAYAMA (BREATHING PRACTICES) AND DHYANA (MEDITATION) AND RELAXATION PRACTICES. METHODS AND ANALYSIS: THIS IS A MULTICENTRE, TWO-ARM, PARALLEL-GROUP, FEASIBILITY RCT WITH BLINDED OUTCOME ASSESSMENT AND INTEGRATED MIXED-METHODS PROCESS EVALUATION. ELIGIBLE PARTICIPANTS SHOULD BE AGED 18-74 YEARS, AT HIGH RISK OF T2DM (FASTING PLASMA GLUCOSE LEVEL 5.6-6.9 MMOL/L) AND SAFE TO PARTICIPATE IN PHYSICAL ACTIVITIES. AT LEAST 64 PARTICIPANTS WILL BE RANDOMISED TO INTERVENTION OR CONTROL GROUP WITH FINAL FOLLOW-UP AT 6 MONTHS. IMPORTANT PARAMETERS, NEEDED TO DESIGN THE MAIN RCT, WILL BE ESTIMATED, SUCH AS SD OF THE OUTCOME MEASURE (FASTING PLASMA GLUCOSE LEVEL AT 6-MONTH FOLLOW-UP), RECRUITMENT, INTERVENTION ADHERENCE, FOLLOW-UP, POTENTIAL CONTAMINATION AND TIME NEEDED TO CONDUCT THE STUDY. SEMISTRUCTURED QUALITATIVE INTERVIEWS WILL BE CONDUCTED WITH UP TO 20-30 PARTICIPANTS, A SAMPLE OF THOSE DECLINING TO PARTICIPATE, FOUR YOGA-DP INSTRUCTORS AND AROUND EIGHT STUDY STAFF TO EXPLORE THEIR PERCEPTIONS AND EXPERIENCES OF TAKING PART IN THE STUDY AND OF THE INTERVENTION, REASONS BEHIND NON-PARTICIPATION, EXPERIENCES OF DELIVERING THE INTERVENTION AND RUNNING THE STUDY, RESPECTIVELY. ETHICS AND DISSEMINATION: ETHICS APPROVAL HAS BEEN OBTAINED FROM THE FOLLOWING RESEARCH ETHICS COMMITTEES: FACULTY OF MEDICINE AND HEALTH SCIENCES, UNIVERSITY OF NOTTINGHAM (UK); CENTRE FOR CHRONIC DISEASE CONTROL (CCDC, INDIA); BAPU NATURE CURE HOSPITAL AND YOGASHRAM (BNCHY, INDIA) AND SWAMI VIVEKANANDA YOGA ANUSANDHANA SAMSTHANA (S-VYASA, INDIA). THE RESULTS WILL BE WIDELY DISSEMINATED AMONG KEY STAKEHOLDERS THROUGH VARIOUS AVENUES. TRIAL REGISTRATION NUMBER: CTRI/2019/05/018893.	2020	

8  339 17 ARE SCREENING BY YOGA INSTRUCTORS AND THEIR PRACTICE PATTERNS IMPORTANT TO PREVENT INJURIES IN YOGA CLIENTS? BACKGROUND AND PURPOSE: LITTLE INFORMATION EXISTS REGARDING THE ASSOCIATION OF YOGA-RELATED INJURIES WITH YOGA INSTRUCTOR (YI) PRACTICE PATTERNS. THEREFORE, THIS CROSS-SECTIONAL SURVEY EXAMINED THE SCREENING AND PRACTICE CHARACTERISTICS OF YI AND ITS RELATIONSHIP WITH YOGA-RELATED INJURIES. METHODS AND MATERIALS: YI FROM NORTHEASTERN US COMPLETED A CUSTOMIZED WEB-BASED 57-ITEM QUESTIONNAIRE. RESULTS: THE RESPONSE RATE OF OUR QUESTIONNAIRE WAS 46%. IN THIS STUDY, ONLY 8.8% OF THE YI REPORTED PHYSICAL PERFORMANCE SCREENING AND 33.7% OF THE PARTICIPANTS DID MEDICAL SCREENINGS WITH THEIR CLIENTS. A BINOMIAL LOGISTIC REGRESSION ANALYSIS WITH THE ABOVE VARIABLES REVEALED THAT ADHERENCE TO TRAINING BY YI (P = 0.031) AND THE USE OF SUN SALUTATIONS (P = 0.002) PREDICTED LOWER YOGA-RELATED INJURIES IN CLIENTS REPORTED BY YI. CONCLUSIONS: REDUCTION IN CLIENT YOGA-RELATED INJURIES WAS PREDICTED BY YI ADHERING TO THEIR TRAINING AND PERFORMING SUN SALUTATIONS IN THEIR CLASSES.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
9 1676 16 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
10  818 24 EFFECT OF YOGA ON COGNITIVE FUNCTIONS IN CLIMACTERIC SYNDROME: A RANDOMISED CONTROL STUDY. OBJECTIVE: TO ASSESS THE EFFICACY OF AN INTEGRATED APPROACH OF YOGA THERAPY (IAYT) ON COGNITIVE ABILITIES IN CLIMACTERIC SYNDROME. DESIGN: A RANDOMISED CONTROL STUDY WHEREIN THE PARTICIPANTS WERE DIVIDED INTO EXPERIMENTAL AND CONTROL GROUPS. SETTINGS: FOURTEEN CENTRES OF SWAMI VIVEKANANDA YOGA RESEARCH FOUNDATION, BANGALORE, INDIA. SAMPLE: ONE HUNDRED AND EIGHT PERIMENOPAUSAL WOMEN BETWEEN 40 AND 55 YEARS WITH FOLLICLE-STIMULATING HORMONE LEVEL EQUAL TO OR GREATER THAN 15 MIU/ML. ONE HUNDRED AND TWENTY PERIMENOPAUSAL WOMEN WERE RANDOMLY ALLOTTED INTO THE YOGA AND THE CONTROL GROUPS. METHODS: THE YOGA GROUP PRACTISED A MODULE COMPRISING BREATHING PRACTICES, SUN SALUTATION AND CYCLIC MEDITATION, WHEREAS THE CONTROL GROUP PRACTISED A SET OF SIMPLE PHYSICAL EXERCISES, UNDER SUPERVISION (1 HOUR/DAY, 5 DAYS/WEEK FOR 8 WEEKS). MAIN OUTCOME MEASURES: ASSESSMENTS WERE MADE BY VASOMOTOR SYMPTOM CHECKLIST, SIX-LETTER CANCELLATION TEST (SLCT) FOR ATTENTION AND CONCENTRATION AND PUNIT GOVIL INTELLIGENCE MEMORY SCALE (PGIMS) WITH TEN SUBTESTS. RESULTS: THE WILCOXON TEST SHOWED SIGNIFICANT (P < 0.001) REDUCTION IN HOT FLUSHES, NIGHT SWEATS AND SLEEP DISTURBANCE IN YOGA GROUP, WITH A TREND OF SIGNIFICANT DIFFERENCE BETWEEN GROUPS AT P = 0.06 ON MANN-WHITNEY TEST IN NIGHT SWEATS. THERE WAS NO CHANGE WITHIN OR BETWEEN GROUPS IN THE CONTROL GROUP. THE SLCT SCORE AND THE PGIMS SHOWED SIGNIFICANT IMPROVEMENT IN EIGHT OF TEN SUBTESTS IN THE YOGA GROUP AND SIX OF TEN SUBTESTS IN THE CONTROL GROUP. THE YOGA GROUP PERFORMED SIGNIFICANTLY BETTER (P < 0.001) WITH HIGHER EFFECT SIZES IN SLCT AND SEVEN TESTS OF PGIMS COMPARED WITH THE CONTROL GROUP. CONCLUSIONS: INTEGRATED APPROACH OF YOGA THERAPY CAN IMPROVE HOT FLUSHES AND NIGHT SWEATS. IT ALSO CAN IMPROVE COGNITIVE FUNCTIONS SUCH AS REMOTE MEMORY, MENTAL BALANCE, ATTENTION AND CONCENTRATION, DELAYED AND IMMEDIATE RECALL, VERBAL RETENTION AND RECOGNITION TESTS.	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
11  630 15 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
12  969 24 EFFECTS OF AN 8-MONTH YOGA INTERVENTION ON ARTERIAL COMPLIANCE AND MUSCLE STRENGTH IN PREMENOPAUSAL WOMEN. PREVIOUS STUDIES HAVE INDICATED THAT YOGA EXERCISE HAS A POSITIVE EFFECT ON REDUCING BLOOD PRESSURE AND HEART RATE. HOWEVER, NO RANDOMIZED CONTROLLED STUDIES TO DATE HAVE INVESTIGATED ITS EFFECTS ON ARTERIAL COMPLIANCE. THE PURPOSE OF THIS STUDY WAS TO INVESTIGATE THE EFFECTS OF AN 8-MONTH YOGA INTERVENTION ON ARTERIAL COMPLIANCE AND MUSCLE STRENGTH IN NORMAL PREMENOPAUSAL WOMEN 35-50 YEARS OF AGE. THIRTY-FOUR WOMEN WERE RANDOMLY ASSIGNED EITHER TO A YOGA EXERCISE GROUP (YE, N = 16) OR A CONTROL GROUP (CON, N = 18). PARTICIPANTS IN YE GROUP PERFORMED 60 MINUTES OF AN ASHTANGA YOGA SERIES 2 TIMES/WEEK WITH ONE DAY BETWEEN SESSIONS FOR 8 MONTHS. EACH YOGA SESSION CONSISTED OF 15 MINUTES OF WARM-UP EXERCISES, 35 MINUTES OF ASHTANGA YOGA POSTURES AND 10 MINUTES OF COOL-DOWN WITH RELAXATION; AND THE SESSION INTENSITY WAS PROGRESSIVELY INCREASED DURING THE 8 MONTHS. PARTICIPANTS IN CON WERE ENCOURAGED TO MAINTAIN THEIR NORMAL DAILY LIFESTYLES MONITORED BY THE BONE-SPECIFIC PHYSICAL ACTIVITY QUESTIONNAIRE AT 2 MONTH INTERVALS FOR 8 MONTHS. ARTERIAL COMPLIANCE (PULSE CONTOUR ANALYSIS) AND MUSCLE STRENGTH (1 REPETITION MAXIMUM) WERE ASSESSED AT BASELINE AND AFTER THE INTERVENTION. ARTERIAL COMPLIANCE OF THE LARGE AND SMALL ARTERIES WAS NOT AFFECTED BY THE 8 MONTH YOGA TRAINING (P > 0.05). ALSO, THERE WERE NO SIGNIFICANT (P > 0.05) GROUP, TIME, OR GROUP X TIME INTERACTION EFFECTS FOR CARDIOVASCULAR VARIABLES. YE GROUP SIGNIFICANTLY (P < 0.01) IMPROVED LEG PRESS MUSCLE STRENGTH COMPARED TO CON (11.4% VS. -6.5%). EIGHT MONTHS OF ASHTANGA YOGA TRAINING WAS BENEFICIAL FOR IMPROVING LEG PRESS STRENGTH, BUT NOT ARTERIAL COMPLIANCE IN PREMENOPAUSAL WOMEN. KEY POINTSTHE 8 MONTH YOGA TRAINING DID NOT AFFECT ARTERIAL COMPLIANCE OF THE LARGE AND SMALL ARTERIES.NONE OF THE CARDIOVASCULAR VARIABLES WERE CHANGED BY THE YOGA INTERVENTION.ISOTONIC MUSCLE STRENGTH WAS NOT ALTERED BY THE YOGA INTERVENTION, WITH THE EXCEPTION OF LEG PRESS.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
13  324 19 ANTHROPOMETRIC, BIOCHEMICAL AND CLINICAL PARAMETERS IN CLIMACTERIC YOGA PRACTITIONERS. OBJECTIVE: THIS STUDY AIMED TO EVALUATE ANTHROPOMETRIC, BIOCHEMICAL AND CLINICAL PARAMETERS IN CLIMACTERIC YOGA PRACTITIONERS. METHODS: THIS STUDY INVESTIGATED 108 CLIMACTERIC WOMEN. WE RECRUITED 28 WOMEN BETWEEN 40 AND 65 YEARS OLD WHO STARTED YOGA PRACTICES IN PREMENOPAUSE AND HAD ALREADY PRACTICED FOR AT LEAST 5 YEARS. AS CONTROLS, WE SELECTED 30 PHYSICAL ACTIVITY (PA) PRACTITIONERS WHO HAD PRACTICED FOR AT LEAST 5 YEARS AND 50 SEDENTARY WOMEN IN THE SAME AGE RANGE. WE CONDUCED ANTHROPOMETRIC, BIOCHEMICAL AND BLOOD PRESSURE MEASUREMENTS. RESULTS: THE YOGA GROUP HAD SIGNIFICANTLY LOWER FASTING BLOOD GLUCOSE THAN THE PA PRACTITIONERS AND SEDENTARY WOMEN. YOGA PRACTITIONERS ALSO HAD LOWER WEIGHT, BODY MASS INDEX, WAIST CIRCUMFERENCE, BODY FAT PERCENTAGE AND WAIST-TO-HEIGHT RATIO; HIGHER LEVELS OF HIGH-DENSITY LIPOPROTEIN CHOLESTEROL; LOWER LEVELS OF TRIGLYCERIDES, INSULIN, HOMEOSTASIS MODEL ASSESSMENT OF INSULIN RESISTANCE, URIC ACID, APOLIPOPROTEIN B AND HIGH-SENSITIVITY C-REACTIVE PROTEIN; AND LOWER FREQUENCY OF METABOLIC SYNDROME, LIPID ACCUMULATION PRODUCT, VISCERAL ADIPOSITY INDEX AND SYSTOLIC BLOOD PRESSURE THAN THE SEDENTARY WOMEN. CONCLUSION: YOGA PRACTITIONERS HAD LOWER GLUCOSE SERUM CONCENTRATIONS THAN THE PA PRACTITIONERS AND SEDENTARY WOMEN. OVERALL, THE YOGA GROUP ALSO HAD BETTER ANTHROPOMETRIC, BIOCHEMICAL AND CLINICAL VARIABLES THAN THE OTHER GROUPS. ALTHOUGH FURTHER INVESTIGATION IS REQUIRED, YOGA PRACTICE IN PREMENOPAUSE SEEMS TO BE BENEFICIAL FOR WOMEN WHEN THEY REACH MENOPAUSE.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
14 1871 22 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
15 1741 21 PHYSICAL DEMAND PROFILES OF HATHA YOGA POSTURES PERFORMED BY OLDER ADULTS. UNDERSTANDING THE PHYSICAL DEMANDS PLACED UPON THE MUSCULOSKELETAL SYSTEM BY INDIVIDUAL POSTURES MAY ALLOW EXPERIENCED INSTRUCTORS AND THERAPISTS TO DEVELOP SAFE AND EFFECTIVE YOGA PROGRAMS WHICH REDUCE UNDESIRABLE SIDE EFFECTS. THUS, WE USED BIOMECHANICAL METHODS TO QUANTIFY THE LOWER EXTREMITY JOINT ANGLES, JOINT MOMENTS OF FORCE, AND MUSCLE ACTIVITIES OF 21 HATHA YOGA POSTURES, COMMONLY USED IN SENIOR YOGA PROGRAMS. TWENTY OLDER ADULTS, 70.7 YEARS +/- 3.8 YEARS, PARTICIPATED IN A 32-WK YOGA CLASS (2 D/WK) WHERE THEY LEARNED INTRODUCTORY AND INTERMEDIATE POSTURES (ASANAS). THEY THEN PERFORMED THE ASANAS IN A MOTION ANALYSIS LABORATORY. KINEMATIC, KINETIC, AND ELECTROMYOGRAPHIC DATA WAS COLLECTED OVER THREE SECONDS WHILE THE PARTICIPANTS HELD THE POSES STATICALLY. PROFILES ILLUSTRATING THE POSTURES AND INCLUDING THE BIOMECHANICAL DATA WERE THEN GENERATED FOR EACH ASANA. OUR FINDINGS DEMONSTRATED THAT HATHA YOGA POSTURES ENGENDERED A RANGE OF APPRECIABLE JOINT ANGLES, JMOFS, AND MUSCLE ACTIVITIES ABOUT THE ANKLE, KNEE, AND HIP, AND THAT DEMANDS ASSOCIATED WITH SOME POSTURES AND POSTURE MODIFICATIONS WERE NOT ALWAYS INTUITIVE. THEY ALSO DEMONSTRATED THAT ALL OF THE POSTURES ELICITED APPRECIABLE RECTUS ABDOMINIS ACTIVITY, WHICH WAS UP TO 70% OF THAT INDUCED DURING WALKING.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
16 1305 18 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
17  992 22 EFFECTS OF HATHA YOGA PRACTICE ON THE HEALTH-RELATED ASPECTS OF PHYSICAL FITNESS. TEN HEALTHY, UNTRAINED VOLUNTEERS (NINE FEMALES AND ONE MALE), RANGING IN AGE FROM 18-27 YEARS, WERE STUDIED TO DETERMINE THE EFFECTS OF HATHA YOGA PRACTICE ON THE HEALTH-RELATED ASPECTS OF PHYSICAL FITNESS, INCLUDING MUSCULAR STRENGTH AND ENDURANCE, FLEXIBILITY, CARDIORESPIRATORY FITNESS, BODY COMPOSITION, AND PULMONARY FUNCTION. SUBJECTS WERE REQUIRED TO ATTEND A MINIMUM OF TWO YOGA CLASSES PER WEEK FOR A TOTAL OF 8 WEEKS. EACH YOGA SESSION CONSISTED OF 10 MINUTES OF PRANAYAMAS (BREATH-CONTROL EXERCISES), 15 MINUTES OF DYNAMIC WARM-UP EXERCISES, 50 MINUTES OF ASANAS (YOGA POSTURES), AND 10 MINUTES OF SUPINE RELAXATION IN SAVASANA (CORPSE POSE). THE SUBJECTS WERE EVALUATED BEFORE AND AFTER THE 8-WEEK TRAINING PROGRAM. ISOKINETIC MUSCULAR STRENGTH FOR ELBOW EXTENSION, ELBOW FLEXION, AND KNEE EXTENSION INCREASED BY 31%, 19%, AND 28% (P<0.05), RESPECTIVELY, WHEREAS ISOMETRIC MUSCULAR ENDURANCE FOR KNEE FLEXION INCREASED 57% (P<0.01). ANKLE FLEXIBILITY, SHOULDER ELEVATION, TRUNK EXTENSION, AND TRUNK FLEXION INCREASED BY 13% (P<0.01), 155% (P<0.001), 188% (P<0.001), AND 14% (P<0.05), RESPECTIVELY. ABSOLUTE AND RELATIVE MAXIMAL OXYGEN UPTAKE INCREASED BY 7% AND 6%, RESPECTIVELY (P<0.01). THESE FINDINGS INDICATE THAT REGULAR HATHA YOGA PRACTICE CAN ELICIT IMPROVEMENTS IN THE HEALTH-RELATED ASPECTS OF PHYSICAL FITNESS.

18  968 26 EFFECTS OF AN 8-MONTH ASHTANGA-BASED YOGA INTERVENTION ON BONE METABOLISM IN MIDDLE-AGED PREMENOPAUSAL WOMEN: A RANDOMIZED CONTROLLED STUDY. ALTHOUGH YOGA HAS THE POTENTIAL TO BE AN ALTERNATIVE PHYSICAL ACTIVITY TO ENHANCE BONE HEALTH, THERE IS A LACK OF HIGH QUALITY EVIDENCE FOR THIS TYPE OF INTERVENTION. THE PURPOSE OF THIS RANDOMIZED CONTROLLED TRIAL WAS TO EXAMINE THE EFFECTS OF A PROGRESSIVE 8-MONTH ASHTANGA-BASED YOGA PROGRAM ON BONE TURNOVER MARKERS (BTM), AREAL BONE MINERAL DENSITY (ABMD) AND VOLUMETRIC BONE CHARACTERISTICS IN PREMENOPAUSAL WOMEN. THIRTY-FOUR PREMENOPAUSAL WOMEN (35-50 YEARS) WERE RANDOMLY ASSIGNED EITHER TO A YOGA GROUP (YE, N = 16) OR A CONTROL GROUP (CON, N = 18). PARTICIPANTS IN YE GROUP PERFORMED 60 MINUTES OF AN ASHTANGA-BASED YOGA SERIES 2 TIMES/WEEK WITH ONE DAY BETWEEN SESSIONS FOR 8 MONTHS, AND THE SESSION INTENSITY WAS PROGRESSIVELY INCREASED BY ADDING THE NUMBER OF SUN SALUTATIONS (SS). PARTICIPANTS IN CON WERE ENCOURAGED TO MAINTAIN THEIR NORMAL DAILY LIFESTYLES MONITORED BY THE BONE SPECIFIC PHYSICAL ACTIVITY QUESTIONNAIRE (BPAQ) AT 2 MONTH INTERVALS FOR 8 MONTHS. BODY COMPOSITION WAS MEASURED BY DUAL ENERGY X-RAY ABSORPTIOMETRY (DXA). BONE FORMATION (BONE ALKALINE PHOSPHATASE, BONE ALP) AND BONE RESORPTION (TARTRATE-RESISTANT ACID PHOSPHATASE-5B, TRAP5B) MARKERS WERE ASSESSED AT BASELINE AND AFTER 8 MONTHS. ABMD OF TOTAL BODY, LUMBAR SPINE AND DUAL PROXIMAL FEMUR AND TIBIA BONE CHARACTERISTICS WERE MEASURED USING DXA AND PERIPHERAL QUANTITATIVE COMPUTED TOMOGRAPHY (PQCT), RESPECTIVELY. WE FOUND THAT THE SERUM BONE ALP CONCENTRATIONS WERE MAINTAINED IN YE, BUT SIGNIFICANTLY (P = 0.005) DECREASED IN CON AFTER THE 8 MONTH INTERVENTION, AND THERE WERE SIGNIFICANT (P = 0.002) GROUP DIFFERENCES IN BONE ALP PERCENT CHANGES (YE 9.1 +/- 4.0% VS. CON -7.1 +/- 2.3%). NO CHANGES IN TRAP5B WERE FOUND IN EITHER GROUP. THE 8-MONTH YOGA PROGRAM DID NOT INCREASE ABMD OR TIBIA BONE STRENGTH VARIABLES. BODY COMPOSITION RESULTS SHOWED NO CHANGES IN WEIGHT, FAT MASS, OR % FAT, BUT SMALL SIGNIFICANT INCREASES IN BONE FREE LEAN BODY MASS OCCURRED IN BOTH GROUPS. THE FINDINGS OF THIS STUDY SUGGEST THAT REGULAR LONG-TERM ASHTANGA YOGA HAD A SMALL POSITIVE EFFECT ON BONE FORMATION BUT DID NOT ALTER ABMD OR TIBIA BONE CHARACTERISTICS IN PREMENOPAUSAL WOMEN. KEY POINTSREGULAR LONG-TERM ASHTANGA-BASED YOGA PROGRAM HAD A SMALL POSITIVE EFFECT ON BONE FORMATION, BUT NO EFFECTS WERE FOUND ON BONE RESORPTION.NONE OF THE BONE DENSITY OR GEOMETRY VARIABLES WERE CHANGED BY THE 8-MONTH ASHTANGA-BASED YOGA INTERVENTION.FUTURE YOGA INTERVENTIONS SHOULD FOCUS ON LONGER DURATION AND GREATER FREQUENCY TO ELICIT IMPROVEMENTS IN BONE MINERAL DENSITY.	2015	
                                               
19 2306 27 TRAINING BENEFITS AND INJURY RISKS OF STANDING YOGA APPLIED IN MUSCULOSKELETAL PROBLEMS: LOWER LIMB BIOMECHANICAL ANALYSIS. STANDING YOGA POSES STRENGTHEN A PERSON'S LEGS AND HELPS TO ACHIEVE THE GOAL OF MUSCULOSKELETAL REHABILITATION, BUT INADEQUATE EXERCISE PLANNING CAN CAUSE INJURIES. THIS STUDY INVESTIGATED CHANGES IN THE ELECTROMYOGRAM AND JOINT MOMENTS OF FORCE (JMOFS) OF LOWER EXTREMITIES DURING COMMON STANDING YOGA POSES IN ORDER TO EXPLORE THE FEASIBILITY AND POSSIBLE INJURY RISK IN DEALING WITH MUSCULOSKELETAL PROBLEMS. ELEVEN YOGA INSTRUCTORS WERE RECRUITED TO EXECUTE FIVE YOGA POSES (CHAIR, TREE, WARRIOR 1, 2, AND 3). THE RESULTS REVEALED SIGNIFICANT DIFFERENCES IN HIP, KNEE, AND ANKLE JMOFS AND VARYING DEGREES OF MUSCLE ACTIVATION AMONG THE POSES. AMONG THESE POSES, RECTUS FEMORIS MUSCLE ACTIVATION DURING THE CHAIR POSE WAS THE HIGHEST, WARRIOR 2 PRODUCED THE HIGHEST MUSCLE ACTIVATION IN THE VASTUS LATERALIS OF THE FRONT LIMB, WHILE WARRIOR 1 HAD THE HIGHEST MUSCLE ACTIVATION IN THE VASTUS MEDIALIS OF THE BACK LIMB. THEREFORE, ALL THREE POSES CAN POSSIBLY BE SUGGESTED AS A THERAPEUTIC INTERVENTION FOR QUADRICEPS STRENGTHENING. WARRIOR 1 WAS POSSIBLY SUGGESTED AS A THERAPEUTIC INTERVENTION IN ORDER TO REDUCE EXCESSIVE LATERAL OVERLOAD OF THE PATELLA, BUT THE POSSIBLE ADVERSE EFFECTS OF WARRIOR 2 WITH THE HIGHEST KNEE ADDUCTOR JMOF IN THE BACK LIMB COULD RAISE JOINT REACTION FORCES ACROSS THE MEDIAL CONDYLES. IN SINGLE-LEG BALANCE POSTURES, WARRIOR 3 HAD UNIQUE TRAINING EFFECTS ON THE HAMSTRING, AND IS THEREFORE SUGGESTED AS A PART OF HAMSTRING REHABILITATION EXERCISES. THE TREE POSE INDUCED LOW LOWER-EXTREMITY JMOFS AND A LOW LEVEL OF THIGH MUSCLE ACTIVATIONS WHEN IT WAS PERFORMED BY SENIOR INSTRUCTORS WITH EXCELLENT BALANCE CONTROL; HOWEVER, FOR YOGA BEGINNERS WITH INSUFFICIENT STABILITY, IT WILL BE A USEFUL TRAINING MODE FOR STRENGTHENING THE MUSCLES THAT HELP TO KEEP ONE UPRIGHT. THIS STUDY QUANTIFIED THE PHYSICAL DEMANDS OF YOGA POSES USING BIOMECHANICAL DATA AND ELUCIDATED THE STRUCTURES AND PRINCIPLES UNDERLYING EACH YOGA MOVEMENT. THIS IS CRUCIAL FOR YOGA PRACTITIONERS.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
20  938 18 EFFECTS OF 1-YEAR YOGA ON CARDIOVASCULAR RISK FACTORS IN MIDDLE-AGED AND OLDER ADULTS WITH METABOLIC SYNDROME: A RANDOMIZED TRIAL. BACKGROUND: METABOLIC SYNDROME (METS) IS A CLUSTERING OF CARDIOVASCULAR RISK FACTORS, WHICH IS ASSOCIATED WITH DIABETES MELLITUS AND CARDIOVASCULAR DISEASE. LIFESTYLE INTERVENTIONS APPLIED TO PEOPLE WITH METS HAS CONSIDERABLE BENEFICIAL EFFECTS ON DISEASE PREVENTIVE OUTCOMES. THIS STUDY AIMED TO EXAMINE THE EFFECTS OF 1-YEAR OF YOGA EXERCISE ON THE CARDIOVASCULAR RISK FACTORS INCLUDING CENTRAL OBESITY, HYPERTENSION, DYSLIPIDEMIA AND HYPERGLYCEMIA IN MIDDLE-AGED AND OLDER HONG KONG CHINESE ADULTS WITH METS. METHODS: ADULTS DIAGNOSED WITH METS USING NATIONAL CHOLESTEROL EDUCATION PROGRAM CRITERIA (N = 182; MEAN +/- SD AGE = 56 +/- 9.1) WERE RANDOMLY ASSIGNED TO A 1-YEAR YOGA INTERVENTION GROUP OR CONTROL GROUP. SYSTOLIC AND DIASTOLIC BLOOD PRESSURE, WAIST CIRCUMFERENCE, FASTING PLASMA GLUCOSE, TRIGLYCERIDES, AND HIGH-DENSITY LIPOPROTEIN CHOLESTEROL WERE EXAMINED AT BASELINE, MIDWAY, AND ON COMPLETION OF THE STUDY. PHYSICAL ACTIVITY LEVEL AND CALORIC INTAKE WERE ASSESSED AND INCLUDED IN THE COVARIATE ANALYSES. RESULTS: A REDUCTION OF THE NUMBER OF DIAGNOSTIC COMPONENTS FOR METS WAS FOUND TO BE ASSOCIATED WITH THE YOGA INTERVENTION. WAIST CIRCUMFERENCE WAS SIGNIFICANTLY IMPROVED AFTER THE 1-YEAR YOGA INTERVENTION. A TREND TOWARDS A DECREASE IN SYSTOLIC BLOOD PRESSURE WAS OBSERVED FOLLOWING YOGA INTERVENTION. CONCLUSION: THESE RESULTS SUGGEST THAT YOGA EXERCISE IMPROVES THE CARDIOVASCULAR RISK FACTORS INCLUDING CENTRAL OBESITY AND BLOOD PRESSURE IN MIDDLE-AGED AND OLDER ADULTS WITH METS. THESE FINDINGS SUPPORT THE COMPLEMENTARY BENEFICIAL ROLE OF YOGA IN MANAGING METS.	2015
