1 1377 106 IMPACT OF HOT YOGA ON ARTERIAL STIFFNESS AND QUALITY OF LIFE IN NORMAL AND OVERWEIGHT/OBESE ADULTS. BACKGROUND: OBESITY IS ASSOCIATED WITH ARTERIAL STIFFENING AND DIMINISHED QUALITY OF LIFE. BIKRAM YOGA MAY BE A FEASIBLE ALTERNATIVE TO TRADITIONAL EXERCISE AMONG OBESE INDIVIDUALS. ACCORDINGLY, THE PURPOSE OF THIS STUDY WAS TO INVESTIGATE THE IMPACT OF BIKRAM YOGA, A HEATED STYLE OF HATHA YOGA, ON ARTERIAL STIFFNESS IN NORMAL AND OVERWEIGHT/OBESE ADULTS. METHODS: FORTY-THREE (23 NORMAL BODY MASS INDEX OR BMI; 20 OVERWEIGHT/OBESE) APPARENTLY HEALTHY PARTICIPANTS COMPLETED AN 8-WEEK BIKRAM YOGA INTERVENTION. BODY COMPOSITION WAS ESTIMATED VIA DUAL ENERGY X-RAY ABSORPTIOMETRY, ARTERIAL STIFFNESS WAS MEASURED VIA BRACHIALANKLE PULSE WAVE VELOCITY, AND HEALTH-RELATED QUALITY OF LIFE WAS ASSESSED VIA RAND 36-ITEM SHORT FORM SURVEY AT BASELINE AND AT THE END OF THE 8-WEEK INTERVENTION. RESULTS: AFTER THE INTERVENTION, BRACHIAL-ANKLE PULSE WAVE VELOCITY DECREASED (P < .05) IN OVERWEIGHT/OBESE PARTICIPANTS WHILE NO SUCH CHANGES WERE OBSERVED IN NORMAL BMI PARTICIPANTS. IN THE QUALITY OF LIFE MEASURES, EMOTIONAL WELL-BEING IMPROVED (P < .05) IN BOTH GROUPS, AND GENERAL HEALTH IMPROVED (P < .05) ONLY IN THE NORMAL WEIGHT BMI GROUP. CONCLUSION: BIKRAM YOGA AMELIORATES ARTERIAL STIFFNESS IN OVERWEIGHT/OBESE ADULTS AND CAN POSITIVELY IMPACT QUALITY OF LIFE REGARDLESS OF BMI.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
2 1102  37 EFFECTS OF YOGA TRAINING ON BODY COMPOSITION AND OXIDANT-ANTIOXIDANT STATUS AMONG HEALTHY MALE. BACKGROUND: THE STRESSFUL CONDITION MAY CAUSE OXIDATIVE STRESS, WHICH IS RESPONSIBLE FOR VARIOUS DISEASES. AIMS: THE PRESENT STUDY WAS DESIGNED TO FIND OUT WHETHER YOGA HAS IMPACT ON THE REDUCTION OF OXIDATIVE STRESS. METHODS: FOR THE PRESENT STUDY, 95 (N = 95) HEALTHY MALE VOLUNTEERS WITHIN THE AGE GROUP OF 18-24 YEARS WERE INCLUDED, 35 (N = 35) VOLUNTEERS WERE EXCLUDED. THE REMAINING 60 (N = 60) VOLUNTEERS WERE RANDOMLY DIVIDED INTO TWO GROUPS: (A) YOGA GROUP (N = 30) AND (B) CONTROL GROUP (N = 30). YOGA TRAINING WAS GIVEN FOR 60 MIN PER DAY, 6 DAYS PER WEEK FOR 12 WEEKS IN THE YOGA GROUP, WITH NO YOGA TRAINING IN CONTROL GROUP. ASSESSMENT OF BODY COMPOSITION AND OXIDANT-ANTIOXIDANT STATUS WERE PERFORMED IN BOTH THE GROUPS AT BASELINE, BEFORE YOGA TRAINING (0 WEEK) AND AFTER (12 WEEKS) OF THE TRAINING. RESULTS: SIGNIFICANT REDUCTION (P < 0.001) IN THE PERCENTAGE OF BODY FAT AND MALONDIALDEHYDE; SIGNIFICANT ELEVATION (P < 0.001) IN SUPEROXIDE DISMUTASE, CATALASE, REDUCED GLUTATHIONE AND ASCORBIC ACID LEVELS WERE NOTED IN THE YOGA GROUP AFTER 12 WEEKS WHEN COMPARED TO BASELINE DATA (0 WEEK). HOWEVER, THERE WAS NO SIGNIFICANT DIFFERENCE IN HEIGHT, WEIGHT, BODY MASS INDEX, BODY SURFACE AREA AND LEAN BODY MASS AMONG THE YOGA GROUP AFTER 12 WEEKS WHEN COMPARED TO BASELINE DATA. THESE CHANGES MIGHT BE DUE TO YOGA TRAINING. CONCLUSIONS: REGULAR YOGA PRACTICE REDUCES BODY FAT AND OXIDATIVE STRESS. YOGA TRAINING MAY BE HELPFUL TO REDUCE THE CHANCE OF OCCURRENCE OF VARIOUS DISEASES AND HELPS TO MAINTAIN NORMAL HEALTHY LIFESTYLE.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
3 2242  37 THE INFLUENCE OF PHYSICAL ACTIVITY AND YOGA ON CENTRAL ARTERIAL STIFFNESS. PURPOSE: CENTRAL ARTERIAL STIFFNESS IS AN ACCEPTED RISK FACTOR FOR CARDIOVASCULAR DISEASE. WHILE AEROBIC ACTIVITY IS ASSOCIATED WITH REDUCED STIFFNESS THE INFLUENCE OF PRACTICING YOGA IS UNKNOWN. THE AIMS OF THIS STUDY WERE TO: 1) EVALUATE ARTERIAL STIFFNESS IN MIDDLE-AGED ADULTS WHO REGULARLY PRACTICED YOGA, PERFORMED REGULAR EXERCISE, OR WERE INACTIVE, 2) EVALUATE THE REPRODUCIBILITY OF ARTERIAL STIFFNESS MEASURED IN THE LEFT AND RIGHT CAROTID ARTERY AND BY PULSE WAVE VELOCITY (PWV). METHODS: TWENTY SIX HEALTHY SUBJECTS (MALE AND FEMALE, 40-65 YRS OLD) WERE TESTED ON TWO SEPARATE DAYS. CAROTID ARTERY DISTENSIBILITY (DC) WAS MEASURED WITH ULTRASOUND. PHYSICAL ACTIVITY WAS DETERMINED BY QUESTIONNAIRE. RESULTS: YOGA AND AEROBIC SUBJECTS HAD SIMILAR PHYSICAL ACTIVITY LEVELS. YOGA AND AEROBIC GROUPS WERE NOT DIFFERENT IN EITHER DC (P = 0.26) OR PWV (P = 0.21). THE SEDENTARY GROUP HAD LOWER DC AND HIGHER PWV COMPARED TO THE AEROBIC AND YOGA GROUPS (BOTH, P < 0.001). STIFFNESS MEASURES WERE RELIABLE DAY TO DAY (COEFFICIENTS OF VARIATION APPROXIMATELY 2.5%) AND SIMILAR BETWEEN LEFT AND RIGHT ARTERIES (CV = 2.2%). CONCLUSION: PHYSICAL ACTIVITY WAS A STRONG PREDICTOR OF BOTH MEASURES OF ARTERIAL STIFFNESS, ALTHOUGH OTHER FACTORS SUCH AS NUTRITIONAL STATUS NEED TO BE ACCOUNTED FOR. AN INDEPENDENT EFFECT OF PRACTICING YOGA COULD NOT BE DETECTED. STIFFNESS MEASURES WERE REPRODUCIBLE AND LEFT AND RIGHT SIDES WERE CONSISTENT WITH EACH OTHER.	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
4  341  43 ARTERIAL BLOOD PRESSURE AND CARDIOVASCULAR RESPONSES TO YOGA PRACTICE. CONTEXT: YOGA IS QUALITATIVELY DIFFERENT FROM ANY OTHER MODE OF PHYSICAL ACTIVITY IN THAT IT CONSISTS OF A UNIQUE COMBINATION OF ISOMETRIC MUSCULAR CONTRACTIONS, STRETCHING EXERCISES, RELAXATION TECHNIQUES, AND BREATHING EXERCISES. IN PARTICULAR, YOGA POSTURES CONSIST OF SYSTEMIC ISOMETRIC CONTRACTIONS THAT ARE KNOWN TO ELICIT MARKED INCREASES IN MEAN BLOOD PRESSURE THAT ARE NOT OBSERVED DURING DYNAMIC EXERCISE. STRETCHING CAN ALSO INDUCE INCREASES IN BLOOD PRESSURE AND SYMPATHETIC NERVE ACTIVITY IN THE MUSCLES. CURRENTLY, NOT MUCH IS KNOWN ABOUT CHANGES IN BLOOD PRESSURE AND OTHER CARDIOVASCULAR RESPONSES TO YOGA PRACTICE. OBJECTIVE: THE STUDY INTENDED TO DETERMINE THE ACUTE EFFECTS OF ONE SESSION OF HATHA YOGA PRACTICE ON BLOOD PRESSURE AND OTHER CARDIOVASCULAR RESPONSES. TO GAIN INSIGHT INTO THE LONG-TERM EFFECTS OF YOGA PRACTICE, BOTH NOVICE (N = 19) AND ADVANCED (N = 18) YOGA PRACTITIONERS WERE STUDIED. DESIGN: THE TWO GROUPS WERE MATCHED FOR AGE, GENDER, BMI, AND BLOOD PRESSURE. SETTING: THE SETTING WAS A RESEARCH LABORATORY AT A UNIVERSITY. PARTICIPANTS: THIRTY-SIX APPARENTLY HEALTHY, NONOBESE, SEDENTARY, OR RECREATIONALLY ACTIVE INDIVIDUALS FROM THE COMMUNITY PARTICIPATED IN THE STUDY. INTERVENTION THE INTERVENTION COMPRISED ONE SESSION OF YOGA PRACTICE, IN WHICH PARTICIPANTS FOLLOWED A CUSTOM MADE INSTRUCTIONAL VIDEO PROVIDING A YOGA ROUTINE THAT CONSISTED OF A SERIES OF 23 HATHA-BASED YOGA POSTURES. OUTCOME MEASURES: PRIOR TO ARRIVING AT THE LABORATORY, EACH PARTICIPANT COMPLETED A RESEARCH HEALTH QUESTIONNAIRE, A TRAINING-STATUS QUESTIONNAIRE, AND A YOGA-EXPERIENCE QUESTIONNAIRE. PRIOR TO THE YOGA PRACTICE, EACH PARTICIPANT'S HEIGHT, BODY FAT PERCENTAGE, TRUNK OR LUMBAR FLEXIBILITY, AND ARTERIAL STIFFNESS AS ASSESSED BY CAROTID FEMORAL PULSE WAVE VELOCITY (CFPWV) WERE MEASURED. FOR EACH POSTURE DURING THE YOGA PRACTICE, THE STUDY CONTINUOUSLY MEASURED SYSTOLIC, MEAN, AND DIASTOLIC BLOOD PRESSURES, HEART RATE, STROKE VOLUME, AND CARDIAC OUTPUT. RESULTS: SYSTOLIC, MEAN, AND DIASTOLIC BLOOD PRESSURES INCREASED SIGNIFICANTLY DURING THE YOGA PRACTICE. THE MAGNITUDE OF THESE INCREASES IN BLOOD PRESSURE WAS GREATEST WITH STANDING POSTURES. HEART RATE AND CARDIAC OUTPUT INCREASED SIGNIFICANTLY DURING YOGA PRACTICE, ESPECIALLY WITH STANDING POSTURES. OVERALL, NO DIFFERENCES EXISTED IN CARDIOVASCULAR RESPONSES BETWEEN THE NOVICE AND ADVANCED PRACTITIONERS THROUGHOUT THE YOGA TESTING SESSION; CFPWV VELOCITY WAS SIGNIFICANTLY AND INVERSELY ASSOCIATED WITH LUMBAR FLEXION BUT NOT WITH SIT-AND-REACH TEST SCORES. CONCLUSIONS: THE RESEARCH TEAM CONCLUDED THAT A VARIETY OF HATHA YOGA POSTURES, ESPECIALLY STANDING POSTURES, EVOKED SIGNIFICANT INCREASES IN BLOOD PRESSURE. THE ELEVATION IN BLOOD PRESSURE DUE TO YOGA PRACTICE WAS ASSOCIATED WITH INCREASES IN CARDIAC OUTPUT AND HEART RATE, WHICH ARE RESPONSES SIMILAR TO THOSE OBSERVED IN ISOMETRIC EXERCISE. THE LACK OF OBVIOUS DIFFERENCES IN BLOOD PRESSURE AND OTHER CARDIOVASCULAR RESPONSES BETWEEN NOVICE AND ADVANCED YOGA PRACTITIONERS SUGGESTS THAT LONG-TERM YOGA PRACTICE DOES NOT ATTENUATE ACUTE YOGA RESPONSES.	2013	

5  297  26 ALTERNATE NOSTRIL BREATHING AT DIFFERENT RATES AND ITS INFLUENCE ON HEART RATE VARIABILITY IN NON PRACTITIONERS OF YOGA. INTRODUCTION: HEART RATE VARIABILITY IS A MEASURE OF MODULATION IN AUTONOMIC INPUT TO THE HEART AND IS ONE OF THE MARKERS OF AUTONOMIC FUNCTIONS. THOUGH THERE ARE MANY STUDIES ON THE LONG TERM INFLUENCE OF BREATHING ON HRV (HEART RATE VARIABILITY) THERE ARE ONLY A FEW STUDIES ON THE IMMEDIATE EFFECT OF BREATHING ESPECIALLY ALTERNATE NOSTRIL BREATHING ON HRV. THIS STUDY FOCUSES ON THE IMMEDIATE EFFECTS OF ALTERNATE NOSTRIL BREATHING AND THE INFLUENCE OF DIFFERENT BREATHING RATES ON HRV. MATERIALS AND METHODS: THE STUDY WAS DONE ON 25 SUBJECTS IN THE AGE GROUP OF 17-35 YEARS. ECG AND RESPIRATION WERE RECORDED BEFORE INTERVENTION AND IMMEDIATELY AFTER THE SUBJECTS WERE ASKED TO PERFORM ALTERNATE NOSTRIL BREATHING FOR FIVE MINUTES. RESULTS: LOW FREQUENCY (LF) WHICH IS A MARKER OF SYMPATHETIC ACTIVITY INCREASED, HIGH FREQUENCY (HF) WHICH IS A MARKER OF PARASYMPATHETIC ACTIVITY DECREASED AND THEIR RATIO LF/HF WHICH IS A MARKER OF SYMPATHO/VAGAL BALANCE INCREASED IMMEDIATELY AFTER 6 AND 12 MINUTES IN COMPARISON TO BASELINE VALUES WHEREAS THERE WAS NO SIGNIFICANT DIFFERENCE IN THE MEANS OF THESE COMPONENTS WHEN BOTH 6 AND 12 MINUTES WERE COMPARED. CONCLUSION: IMMEDIATE EFFECTS OF ALTERNATE NOSTRIL BREATHING ON HRV IN NON PRACTITIONERS OF YOGIC BREATHING ARE VERY DIFFERENT FROM THE LONG TERM INFLUENCE OF YOGIC BREATHING ON HRV WHICH SHOW A PREDOMINANT PARASYMPATHETIC INFLUENCE ON THE HEART.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
6  727  27 EFFECT OF LONG-TERM REGULAR YOGA ON PHYSICAL HEALTH OF YOGA PRACTITIONERS. BACKGROUND: YOGA IS A PHYSICAL, MENTAL, AND SPIRITUAL DISCIPLINE. THE EFFECT OF YOGA ON MENTAL HEALTH HAS BEEN STUDIED EXTENSIVELY IN INDIA BUT LESS IN THE CONTEXT OF PHYSICAL HEALTH. OBJECTIVE: THE OBJECTIVE WAS TO EXPLORE THE EFFECT OF LONG-TERM REGULAR YOGA ON PHYSICAL HEALTH OF YOGA PRACTITIONERS. MATERIALS AND METHODS: IT WAS AN INTERVENTIONAL STUDY. INCLUSION CRITERIA WERE STUDENTS WHO ENROLLED FOR 1-YEAR DIPLOMA COURSE AT THE YOGA CENTER. EXCLUSION CRITERIA WERE NONREGULAR YOGA PRACTITIONERS DURING THE COURSE. PHYSICAL HEALTH PARAMETERS CONSIDERED FOR ASSESSMENT BEFORE AND AFTER THE YOGA COURSE WERE PULMONARY FUNCTION TESTS, MAXIMUM OXYGEN CONSUMPTION (VO2 MAX) USING BRUCE TREADMILL TEST, FLEXIBILITY, BODY COMPOSITION ANALYSIS, AND HEMOGLOBIN LEVEL. PAIRED SAMPLE T-TEST AND CHI-SQUARE TEST WERE USED FOR STATISTICAL ANALYSIS. RESULTS: THE AEROBIC CAPACITY IMPROVED SIGNIFICANTLY IN TERMS OF MEAN (STANDARD DEVIATION [SD]) FORCED VITAL CAPACITY (P < 0.001), FORCED EXPIRATION VOLUME AT THE END OF THE FIRST SECOND (P < 0.001) AS WELL AS PEAK EXPIRATORY FLOW RATE (P = 0.04). THE MEAN (SD) FLEXIBILITY SCORE IMPROVED SIGNIFICANTLY (P < 0.001). SIMILARLY, THE ENDURANCE IMPROVED SIGNIFICANTLY IN TERMS OF MEAN (SD) VO2 MAX (< 0.001) AND TREADMILL TIME (P < 0.001). THERE WAS NO SIGNIFICANT CHANGE IN BODY COMPOSITION AND HEMOGLOBIN LEVEL. CONCLUSIONS: REGULAR YOGA PRACTITIONERS DEMONSTRATED THE IMPROVEMENT IN PULMONARY FUNCTIONS, CARDIORESPIRATORY FITNESS, ENDURANCE, AND FLEXIBILITY.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
7  452  33 CHANGES IN HEART RATE VARIABILITY AFTER YOGA ARE DEPENDENT ON HEART RATE VARIABILITY AT BASELINE AND DURING YOGA: A STUDY SHOWING AUTONOMIC NORMALIZATION EFFECT IN YOGA-NAIVE AND EXPERIENCED SUBJECTS. BACKGROUND: YOGA THERAPY IS WIDELY APPLIED TO THE MAINTENANCE OF HEALTH AND TO TREATMENT OF VARIOUS ILLNESSES. PREVIOUS RESEARCHES INDICATE THE INVOLVEMENT OF AUTONOMIC CONTROL IN ITS EFFECTS, ALTHOUGH THE GENERAL AGREEMENT HAS NOT BEEN REACHED REGARDING THE ACUTE MODULATION OF AUTONOMIC FUNCTION. AIM: THE PRESENT STUDY AIMED AT REVEALING THE ACUTE EFFECT OF YOGA ON THE AUTONOMIC ACTIVITY USING HEART RATE VARIABILITY (HRV) MEASUREMENT. METHODS: TWENTY-SEVEN HEALTHY CONTROLS PARTICIPATED IN THE PRESENT STUDY. FIFTEEN OF THEM (39.5 +/- 8.5 YEARS OLD) WERE NAIVE AND 12 (45.1 +/- 7.0 YEARS OLD) WERE EXPERIENCED IN YOGA. YOGA SKILLS INCLUDED BREATH AWARENESS, TWO TYPES OF ASANA, AND TWO TYPES OF PRANAYAMA. HRV WAS MEASURED AT THE BASELINE, DURING YOGA, AND AT THE RESTING STATE AFTER YOGA. RESULTS: IN BOTH YOGA-NAIVE AND EXPERIENCED PARTICIPANTS, THE CHANGES IN LOW-FREQUENCY (LF) COMPONENT OF HRV AND ITS RATIO TO HIGH-FREQUENCY (HF) COMPONENT (LF/HF) AFTER YOGA WERE FOUND TO BE CORRELATED NEGATIVELY WITH THE BASELINE DATA. THE CHANGES IN LF AFTER YOGA WERE ALSO CORRELATED WITH LF DURING YOGA. THE CHANGES IN HF AS WELL AS THE RAW HRV DATA AFTER YOGA WERE NOT RELATED TO THE BASELINE HRV OR THE HRV DURING YOGA. CONCLUSION: THE RESULTS INDICATE THAT YOGA LEADS TO AN INCREASE IN LF WHEN LF IS LOW AND LEADS TO A DECREASE IN LF WHEN IT IS HIGH AT THE BASELINE. THIS NORMALIZATION OF LF IS DEPENDENT ON THE AUTONOMIC MODULATION DURING YOGA AND MAY UNDERLIE THE CLINICAL EFFECTIVENESS OF YOGA THERAPY BOTH IN YOGA-NAIVE AND EXPERIENCED SUBJECTS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
8 2075  40 THE EFFECT OF BIKRAM YOGA ON ARTERIAL STIFFNESS IN YOUNG AND OLDER ADULTS. BACKGROUND AND OBJECTIVE: BIKRAM YOGA IS THE MOST POPULAR FORM OF HOT YOGA, DESPITE THE LIMITED INFORMATION AVAILABLE ON ITS CARDIOVASCULAR BENEFITS. THIS STUDY SOUGHT TO DETERMINE THE EFFECT OF BIKRAM YOGA ON ARTERIAL STIFFNESS AND INSULIN RESISTANCE IN YOUNG AND OLDER ADULTS. METHODS: TWENTY-FOUR YOUNG (MEAN AGE+/-STANDARD DEVIATION, 30+/-1 YEARS) AND 18 MIDDLE-AGED AND OLDER (MEAN AGE, 53+/-2 YEARS) ADULTS COMPLETED AN 8-WEEK BIKRAM YOGA INTERVENTION. BIKRAM YOGA CLASSES WERE PERFORMED FOR 90 MINUTES PER SESSION, THREE TIMES PER WEEK, IN A ROOM HEATED TO 40.5 DEGREES C WITH 40%--60% RELATIVE HUMIDITY. RESULTS: BODY MASS, BODY FAT PERCENTAGE, BLOOD PRESSURE, AND FASTING BLOOD GLUCOSE AND TRIGLYCERIDE CONCENTRATIONS DID NOT SIGNIFICANTLY CHANGE AS A RESULT OF THE INTERVENTION IN EITHER THE YOUNG OR THE OLDER GROUP. TRUNK FLEXIBILITY, AS MEASURED BY THE SIT-AND-REACH TEST, INCREASED IN BOTH GROUPS (P<0.01). TOTAL (P<0.05) AND LOW-DENSITY LIPOPROTEIN CHOLESTEROL (P<0.05) LEVELS, PLASMA INSULIN CONCENTRATIONS (P<0.01), AND SCORES ON THE HOMEOSTATIC MODEL OF THE ASSESSMENT OF INSULIN RESISTANCE (P<0.01) DECREASED IN OLDER ADULTS, WHEREAS TOTAL AND HIGH-DENSITY LIPOPROTEIN CHOLESTEROL CONCENTRATIONS WERE REDUCED IN YOUNG ADULTS (ALL P<0.05). CAROTID ARTERY COMPLIANCE (P<0.05) WAS INCREASED AND BETA-STIFFNESS INDEX DECREASED IN YOUNG (P<0.05) BUT NOT IN OLDER ADULTS. CAROTID PULSE PRESSURE DID NOT SIGNIFICANTLY CHANGE IN EITHER GROUP. CONCLUSION: A RELATIVELY SHORT-TERM BIKRAM YOGA INTERVENTION IMPROVED ARTERIAL STIFFNESS IN YOUNG BUT NOT OLDER ADULTS AND SIGNIFICANTLY REDUCED INSULIN RESISTANCE INDEX IN OLDER BUT NOT YOUNG ADULTS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
9  306  31 AN EVALUATION OF THE ABILITY TO VOLUNTARILY REDUCE THE HEART RATE AFTER A MONTH OF YOGA PRACTICE. THE STUDY AIMED AT DETERMINING WHETHER NOVICES TO YOGA WOULD BE ABLE TO REDUCE THEIR HEART RATE VOLUNTARILY AND WHETHER THE MAGNITUDE OF REDUCTION WOULD BE MORE AFTER 30 DAYS OF YOGA TRAINING. TWO GROUPS (YOGA AND CONTROL, N = 12 EACH) WERE ASSESSED ON DAY 1 AND ON DAY 30. DURING THE INTERVENING 30 DAYS, THE YOGA GROUP RECEIVED TRAINING IN YOGA TECHNIQUES WHILE THE CONTROL GROUP CARRIED ON WITH THEIR ROUTINE. AT EACH ASSESSMENT THE BASELINE HEART RATE WAS RECORDED FOR ONE MINUTE, THIS WAS FOLLOWED BY A SIX-MINUTE PERIOD DURING WHICH PARTICIPANTS WERE ASKED TO ATTEMPT TO VOLUNTARILY REDUCE THEIR HEART RATE, USING ANY STRATEGY. BOTH THE BASELINE HEART RATE AND THE LOWEST HEART RATE ACHIEVED VOLUNTARILY DURING THE SIX-MINUTE PERIOD WERE SIGNIFICANTLY LOWER IN THE YOGA GROUP ON DAY 30 COMPARED TO DAY 1 BY A GROUP AVERAGE OF 10.7 BEATS PER MINUTE (I.E., BPM) AND 6.8 BPM, RESPECTIVELY (P < .05, WILCOXON PAIRED SIGNED RANKS TEST). IN CONTRAST, THERE WAS NO SIGNIFICANT CHANGE IN EITHER THE BASELINE HEART RATE OR THE LOWEST HEART RATE ACHIEVED VOLUNTARILY IN THE CONTROL GROUP ON DAY 30 COMPARED TO DAY 1. THE RESULTS SUGGEST THAT YOGA TRAINING CAN ENABLE PRACTITIONERS TO USE THEIR OWN STRATEGIES TO REDUCE THE HEART RATE, WHICH HAS POSSIBLE THERAPEUTIC APPLICATIONS.	2004	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
10 2863  21 YOGA-BASED GUIDED RELAXATION REDUCES SYMPATHETIC ACTIVITY JUDGED FROM BASELINE LEVELS. 35 MALE VOLUNTEERS WHOSE AGES RANGED FROM 20 TO 46 YEARS WERE STUDIED IN TWO SESSIONS OF YOGA-BASED GUIDED RELAXATION AND SUPINE REST. ASSESSMENTS OF AUTONOMIC VARIABLES WERE MADE FOR 15 SUBJECTS, BEFORE, DURING, AND AFTER THE PRACTICES, WHEREAS OXYGEN CONSUMPTION AND BREATH VOLUME WERE RECORDED FOR 25 SUBJECTS BEFORE AND AFTER BOTH TYPES OF RELAXATION. A SIGNIFICANT DECREASE IN OXYGEN CONSUMPTION AND INCREASE IN BREATH VOLUME WERE RECORDED AFTER GUIDED RELAXATION (PAIRED T TEST). THERE WERE COMPARABLE REDUCTIONS IN HEART RATE AND SKIN CONDUCTANCE DURING BOTH TYPES OF RELAXATION. DURING GUIDED RELAXATION THE POWER OF THE LOW FREQUENCY COMPONENT OF THE HEART-RATE VARIABILITY SPECTRUM REDUCED, WHEREAS THE POWER OF THE HIGH FREQUENCY COMPONENT INCREASED, SUGGESTING REDUCED SYMPATHETIC ACTIVITY. ALSO, SUBJECTS WITH A BASELINE RATIO OF LF/HF > 0.5 SHOWED A SIGNIFICANT DECREASE IN THE RATIO AFTER GUIDED RELAXATION, WHILE SUBJECTS WITH A RATIO < OR = 0.5 AT BASELINE SHOWED NO SUCH CHANGE. THE RESULTS SUGGEST THAT SYMPATHETIC ACTIVITY DECREASED AFTER GUIDED RELAXATION BASED ON YOGA, DEPENDING ON THE BASELINE LEVELS.	2002	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
11  674  36 EFFECT OF A SHORT-TERM YOGA-BASED LIFESTYLE INTERVENTION ON HEALTH-RELATED QUALITY OF LIFE IN OVERWEIGHT AND OBESE SUBJECTS. OBJECTIVE: TO STUDY THE EFFECT OF A SHORT-TERM YOGA-BASED LIFESTYLE INTERVENTION ON HEALTH-RELATED QUALITY OF LIFE (HRQOL) IN OVERWEIGHT AND OBESE PERSONS. DESIGN AND SETTING: NONRANDOMIZED, SINGLE-ARM INTERVENTIONAL STUDY CONDUCTED FROM AUGUST 2012 TO MARCH 2015 AT INTEGRAL HEALTH CLINIC, DEPARTMENT OF PHYSIOLOGY, ALL INDIA INSTITUTE OF MEDICAL SCIENCES, NEW DELHI, INDIA. PARTICIPANTS: OVERWEIGHT (BODY-MASS INDEX [BMI], 23-24.9 KG/M(2)) AND OBESE (BMI, >/=25 KG/M(2)) PERSONS (N = 279) AGED 20-60 YEARS. INTERVENTION: PRETESTED YOGA-BASED LIFESTYLE INTERVENTION, INCLUDING ASANAS (POSTURES), PRANAYAMA (BREATHING EXERCISES), RELAXATION TECHNIQUES, LECTURES, GROUP SUPPORT, NUTRITION AWARENESS PROGRAM, AND INDIVIDUALIZED ADVICE. OUTCOME MEASURES: PRIMARY OUTCOME MEASURE WAS HRQOL, MEASURED BY USING SHORT VERSION OF WORLD HEALTH ORGANIZATION QUALITY OF LIFE (WHOQOL-BREF) QUESTIONNAIRE. SECONDARY OUTCOME MEASURES WERE ANTHROPOMETRIC VARIABLES, SYSTOLIC AND DIASTOLIC BLOOD PRESSURE, PULSE RATE, LIPID PROFILE, AND FASTING GLUCOSE. A SUBGROUP ANALYSIS ACCORDING TO SEX WAS ALSO PERFORMED. RESULTS: THE OVERALL QUALITY OF LIFE AND HEALTH IMPROVED AFTER SHORT-TERM YOGA-BASED LIFESTYLE INTERVENTION IN OVERWEIGHT AND OBESE PERSONS. PHYSICAL, PSYCHOLOGICAL AND ENVIRONMENTAL DOMAIN SCORES SIGNIFICANTLY INCREASED FROM BASELINE TO DAY 10, AND EFFICACY WAS NOTED IN BOTH MALE AND FEMALE SUBGROUPS. AFTER 10 DAYS OF INTERVENTION, THE FOLLOWING ALSO DECREASED SIGNIFICANTLY: BODY WEIGHT, BMI, TOTAL BODY FAT, WAIST AND HIP CIRCUMFERENCE, WAIST-TO-HIP RATIO, SYSTOLIC AND DIASTOLIC BLOOD PRESSURE, TOTAL CHOLESTEROL, LOW-DENSITY LIPOPROTEIN, TRIGLYCERIDES, AND FASTING GLUCOSE. CONCLUSION: A SHORT-TERM YOGA-BASED LIFESTYLE INTERVENTION HAD A POSITIVE EFFECT ON HRQOL IN OVERWEIGHT AND OBESE PERSONS.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
12 2076  39 THE EFFECT OF BIKRAM YOGA ON ENDOTHELIAL FUNCTION IN YOUNG AND MIDDLE-AGED AND OLDER ADULTS. THE PURPOSE OF THIS INVESTIGATION WAS TO DETERMINE IF BIKRAM YOGA, A STYLE OF HEATED HATHA YOGA, WOULD IMPROVE ENDOTHELIAL FUNCTION IN YOUNG AND MIDDLE-AGED AND OLDER, HEALTHY ADULTS. THIS TRIAL WAS PERFORMED IN 36 YOUNG (N = 17) AND MIDDLE-AGED AND OLDER ADULTS (N = 19) WHO COMPLETED 3 WEEKLY BIKRAM YOGA CLASSES FOR 8 WEEKS. HEIGHT, BODY WEIGHT AND BODY COMPOSITION WERE DETERMINED AND ENDOTHELIAL FUNCTION WAS MEASURED NONINVASIVELY USING BRACHIAL ARTERY FLOW-MEDIATED DILATION (FMD) BEFORE AND AFTER THE INTERVENTION. NO CHANGES IN BODY WEIGHT, BMI OR BODY FAT PERCENTAGE OCCURRED AS A RESULT OF THE INTERVENTION IN EITHER GROUP. BRACHIAL ARTERY FMD WAS SIGNIFICANTLY INCREASED IN MIDDLE-AGED AND OLDER (P < 0.05) BUT NOT IN YOUNG ADULTS AS A RESULT OF THE INTERVENTION. THE RESULTS DEMONSTRATE THAT A RELATIVELY SHORT-TERM BIKRAM YOGA PRACTICE MIGHT SIGNIFICANTLY IMPROVE VASCULAR ENDOTHELIAL FUNCTION IN MIDDLE-AGED AND OLDER ADULTS. WHILE APPARENTLY HEALTHY INDIVIDUALS IN THIS STUDY EXPERIENCED NO ADVERSE EVENTS, THOSE WITH PREEXISTING CONDITIONS SHOULD TAKE CAUTION AND CONSULT WITH A PHYSICIAN PRIOR TO ENGAGING IN THIS STYLE OF YOGA.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
13 1514  30 IS WEEKLY FREQUENCY OF YOGA PRACTICE SUFFICIENT? PHYSIOLOGICAL EFFECTS OF HATHA YOGA AMONG HEALTHY NOVICE WOMEN. BENEFICIAL PHYSICAL AND PHYSIOLOGICAL HEALTH OUTCOMES OF YOGA PRACTICE ARE WELL-SUPPORTED BY EMPIRICAL DATA. HOWEVER, WHETHER WEEKLY FREQUENCY OF TRAINING IS SUFFICIENT TO EVOKE POSITIVE CHANGES, IS STILL AN OPEN QUESTION. THE PRESENT INTERVENTION STUDY INVESTIGATED THE EFFECTS OF 10 WEEKLY SESSIONS OF BEGINNER LEVEL HATHA YOGA WITH RESPECT TO INDICATORS OF PHYSICAL FITNESS AND PHYSIOLOGICAL MARKERS. 82 YOUNG WOMEN (MEAN AGE OF 22.0 +/- 3.83 YEARS) PARTICIPATED IN THE STUDY. THE YOGA GROUP (N = 49) ATTENDED A YOGA COURSE CONSISTING OF 10 SESSIONS (1.5 H EACH) ON A WEEKLY BASIS. THE CONTROL GROUP (N = 33) DID NOT RECEIVE ANY INTERVENTION. BMI, BODY FAT PERCENTAGE, BALANCE (ONE-LEG-STAND TEST WITH OPEN AND CLOSED EYES, FUNCTIONAL REACH TEST), FLEXIBILITY (SIDE BEND TEST, MODIFIED SIT AND REACH TEST) CORE MUSCLE STRENGTH (PLANK TEST) AS WELL AS RESTING HEART RATE (HR), AND HEART RATE VARIABILITY (HRV) WERE ASSESSED 1 WEEK BEFORE AND AFTER THE COURSE. BOTH FREQUENTIST AND BAYESIAN ANALYSIS SHOWED AN IMPROVEMENT IN FLEXIBILITY AND BALANCE IN THE YOGA GROUP COMPARED TO THE CONTROL GROUP. THE YOGA GROUP SHOWED ALSO INCREASED CORE MUSCLE STRENGTH. NO CHANGES WITH RESPECT TO BMI, BODY FAT PERCENTAGE, RESTING HR AND HRV WERE FOUND. NINETY MINUTE BEGINNER LEVEL HATHA YOGA CLASSES WERE CHARACTERIZED BY 93.39 HR AND 195 KCAL ENERGY CONSUMPTION ON AVERAGE. THE PRESENT FINDINGS SUGGEST THAT WEEKLY SETTING OF A 10-SESSION LONG HATHA YOGA TRAINING LEADS TO IMPROVEMENTS IN BALANCE, FLEXIBILITY AND CORE MUSCLE STRENGTH AMONG HEALTHY YOUNG WOMEN. HOWEVER, FOR CHANGES IN BMI, BODY FAT PERCENTAGE, RESTING HR AND HRV LONGER, AND/OR MORE INTENSE INTERVENTIONS ARE NEEDED.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
14 2775  33 YOGA RESPIRATORY TRAINING IMPROVES RESPIRATORY FUNCTION AND CARDIAC SYMPATHOVAGAL BALANCE IN ELDERLY SUBJECTS: A RANDOMISED CONTROLLED TRIAL. OBJECTIVES: SINCE AGEING IS ASSOCIATED WITH A DECLINE IN PULMONARY FUNCTION, HEART RATE VARIABILITY AND SPONTANEOUS BAROREFLEX, AND RECENT STUDIES SUGGEST THAT YOGA RESPIRATORY EXERCISES MAY IMPROVE RESPIRATORY AND CARDIOVASCULAR FUNCTION, WE HYPOTHESISED THAT YOGA RESPIRATORY TRAINING MAY IMPROVE RESPIRATORY FUNCTION AND CARDIAC AUTONOMIC MODULATION IN HEALTHY ELDERLY SUBJECTS. DESIGN: 76 HEALTHY ELDERLY SUBJECTS WERE ENROLLED IN A RANDOMISED CONTROL TRIAL IN BRAZIL AND 29 COMPLETED THE STUDY (AGE 68 +/- 6 YEARS, 34% MALES, BODY MASS INDEX 25 +/- 3 KG/M(2)). SUBJECTS WERE RANDOMISED INTO A 4-MONTH TRAINING PROGRAM (2 CLASSES/WEEK PLUS HOME EXERCISES) OF EITHER STRETCHING (CONTROL, N=14) OR RESPIRATORY EXERCISES (YOGA, N=15). YOGA RESPIRATORY EXERCISES (BHASTRIKA) CONSISTED OF RAPID FORCED EXPIRATIONS FOLLOWED BY INSPIRATION THROUGH THE RIGHT NOSTRIL, INSPIRATORY APNOEA WITH GENERATION OF INTRATHORACIC NEGATIVE PRESSURE, AND EXPIRATION THROUGH THE LEFT NOSTRIL. PULMONARY FUNCTION, MAXIMUM EXPIRATORY AND INSPIRATORY PRESSURES (PE(MAX) AND PI(MAX), RESPECTIVELY), HEART RATE VARIABILITY AND BLOOD PRESSURE VARIABILITY FOR SPONTANEOUS BAROREFLEX DETERMINATION WERE DETERMINED AT BASELINE AND AFTER 4 MONTHS. RESULTS: SUBJECTS IN BOTH GROUPS HAD SIMILAR DEMOGRAPHIC PARAMETERS. PHYSIOLOGICAL VARIABLES DID NOT CHANGE AFTER 4 MONTHS IN THE CONTROL GROUP. HOWEVER, IN THE YOGA GROUP, THERE WERE SIGNIFICANT INCREASES IN PE(MAX) (34%, P<0.0001) AND PI(MAX) (26%, P<0.0001) AND A SIGNIFICANT DECREASE IN THE LOW FREQUENCY COMPONENT (A MARKER OF CARDIAC SYMPATHETIC MODULATION) AND LOW FREQUENCY/HIGH FREQUENCY RATIO (MARKER OF SYMPATHOVAGAL BALANCE) OF HEART RATE VARIABILITY (40%, P<0.001). SPONTANEOUS BAROREFLEX DID NOT CHANGE, AND QUALITY OF LIFE ONLY MARGINALLY INCREASED IN THE YOGA GROUP. CONCLUSION: RESPIRATORY YOGA TRAINING MAY BE BENEFICIAL FOR THE ELDERLY HEALTHY POPULATION BY IMPROVING RESPIRATORY FUNCTION AND SYMPATHOVAGAL BALANCE.

15 2364  24 VOLUNTARY HEART RATE REDUCTION FOLLOWING YOGA USING DIFFERENT STRATEGIES. BACKGROUND/AIMS: ONE MONTH OF YOGA TRAINING HAS BEEN SHOWN TO REDUCE THE PULSE RATE VOLUNTARILY WITHOUT USING EXTERNAL CUES. HENCE, THE PRESENT STUDY WAS DESIGNED TO UNDERSTAND THE STRATEGIES USED BY YOGA PRACTITIONERS AND AUTONOMIC CHANGES ASSOCIATED WITH VOLUNTARY HEART RATE REDUCTION. MATERIALS AND METHODS: FIFTY VOLUNTEERS (GROUP MEAN AGE +/- S.D., 25.4 +/- 4.8 YEARS; 25 MALES) WERE ASSESSED IN TWO TRIALS ON SEPARATE DAYS. EACH TRIAL WAS FOR 12 MINUTES, WITH A 'PRE' STATE AND 'DURING' STATE OF 6 MINUTES EACH. FOR BOTH TRIALS THE 'PRE' STATE WAS RELAXATION WITH EYES CLOSED. IN THE 'DURING' STATE OF TRIAL I, SUBJECTS WERE ASKED TO VOLUNTARILY REDUCE THEIR HEART RATE USING A STRATEGY OF THEIR CHOICE. FROM THEIR RESPONSES TO SPECIFIC QUESTIONS IT WAS DETERMINED THAT 22 OUT OF 50 PERSONS USED BREATH REGULATION AS A STRATEGY. HENCE, IN THE 'DURING' STATE OF TRIAL II, SUBJECTS WERE ASKED TO VOLUNTARILY REDUCE THEIR HEART RATE BY BREATH REGULATION. RESULTS: IN THE FIRST TRIAL, THE HEART RATE WAS REDUCED BY AN AVERAGE OF 19.6 BEATS PER MINUTE AND IN THE SECOND TRIAL (WITH BREATH REGULATION EXCLUSIVELY) AN AVERAGE DECREASE OF 22.2 BEATS PER MINUTE WAS ACHIEVED. CONCLUSIONS: HENCE, THE STRATEGY USED DID NOT MARKEDLY ALTER THE OUTCOME.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
16  668  40 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.

17 1451  20 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
18  300  21 AN ASSESSMENT OF A SEQUENCE OF YOGA EXERCISES TO PATIENTS WITH ARTERIAL HYPERTENSION. THIS QUASI-EXPERIMENTAL STUDY DESCRIBES THE EFFECTS OF A YOGA SEQUENCE FOLLOWING HEMODYNAMIC AND BIOCHEMICAL PARAMETERS IN PATIENTS WITH HYPERTENSION. THIRTY-THREE VOLUNTEERS PARTICIPATED IN THE STUDY (CONTROL = 16 AND YOGA = 17) FOR FOUR MONTHS. BLOOD PRESSURE MEASUREMENTS, CARDIAC AND RESPIRATORY RATE WERE COLLECTED MONTHLY, WHILE THE BIOCHEMICAL PROFILE WAS TAKEN AT THE BEGINNING AND END OF THE PROGRAM. TO ANALYZE THE DATA, STUDENT'S T TEST AND REPEATED MEASURES ANALYSES WERE PERFORMED. THE YOGA GROUP SHOWED A SIGNIFICANT REDUCTION OF SYSTOLIC BLOOD PRESSURE, HEART AND RESPIRATORY RATE (P < 0.05). AS FOR THE BIOCHEMICAL PROFILE, THE YOGA GROUP SHOWED CORRELATION COEFFICIENTS BETWEEN INITIAL VALUES AND FINAL RESPONSES GREATER THAN THE CONTROL OF FASTING GLUCOSE, TOTAL CHOLESTEROL, LDL-CHOLESTEROL AND TRIGLYCERIDES. THE ELABORATED SEQUENCE PRACTICE PROMOTED SIGNIFICANT CARDIOVASCULAR AND METABOLIC BENEFITS. THE YOGA EXERCISES PERFORMED IN THE PROPOSED SEQUENCE CONSTITUTE COMPLEMENTARY NON-PHARMACOLOGICAL CONTROL OF BLOOD PRESSURE IN PATIENTS WITH HYPERTENSION.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
19 1530  29 IYENGAR YOGA INCREASES CARDIAC PARASYMPATHETIC NERVOUS MODULATION AMONG HEALTHY YOGA PRACTITIONERS. RELAXATION TECHNIQUES ARE ESTABLISHED IN MANAGING OF CARDIAC PATIENTS DURING REHABILITATION AIMING TO REDUCE FUTURE ADVERSE CARDIAC EVENTS. IT HAS BEEN HYPOTHESIZED THAT RELAXATION-TRAINING PROGRAMS MAY SIGNIFICANTLY IMPROVE CARDIAC AUTONOMIC NERVOUS TONE. HOWEVER, THIS HAS NOT BEEN PROVEN FOR ALL AVAILABLE RELAXATION TECHNIQUES. WE TESTED THIS ASSUMPTION BY INVESTIGATING CARDIAC VAGAL MODULATION DURING YOGA.WE EXAMINED 11 HEALTHY YOGA PRACTITIONERS (7 WOMEN AND 4 MEN, MEAN AGE: 43 +/- 11; RANGE: 26-58 YEARS). EACH INDIVIDUAL WAS SUBJECTED TO TRAINING UNITS OF 90 MIN ONCE A WEEK OVER FIVE SUCCESSIVE WEEKS. DURING TWO SESSIONS, THEY PRACTICED A YOGA PROGRAM DEVELOPED FOR CARDIAC PATIENTS BY B.K.S. IYENGAR. ON THREE SESSIONS, THEY PRACTICED A PLACEBO PROGRAM OF RELAXATION. ON EACH TRAINING DAY THEY UNDERWENT AMBULATORY 24 H HOLTER MONITORING. THE GROUP OF YOGA PRACTITIONERS WAS COMPARED TO A MATCHED GROUP OF HEALTHY INDIVIDUALS NOT PRACTICING ANY RELAXATION TECHNIQUES. PARAMETERS OF HEART RATE VARIABILITY (HRV) WERE DETERMINED HOURLY BY A BLINDED OBSERVER. MEAN RR INTERVAL (INTERVAL BETWEEN TWO R-WAVES OF THE ECG) WAS SIGNIFICANTLY HIGHER DURING THE TIME OF YOGA INTERVENTION COMPARED TO PLACEBO AND TO CONTROL (P < 0.001 FOR BOTH). THE INCREASE IN HRV PARAMETERS WAS SIGNIFICANTLY HIGHER DURING YOGA EXERCISE THAN DURING PLACEBO AND CONTROL ESPECIALLY FOR THE PARAMETERS ASSOCIATED WITH VAGAL TONE, I.E. MEAN STANDARD DEVIATION OF NN (NORMAL BEAT TO NORMAL BEAT OF THE ECG) INTERVALS FOR ALL 5-MIN INTERVALS (SDNNI, P < 0.001 FOR BOTH) AND ROOT MEAN SQUARE SUCCESSIVE DIFFERENCE (RMSSD, P < 0.01 FOR BOTH). IN CONCLUSION, RELAXATION BY YOGA TRAINING IS ASSOCIATED WITH A SIGNIFICANT INCREASE OF CARDIAC VAGAL MODULATION. SINCE THIS METHOD IS EASY TO APPLY WITH NO SIDE EFFECTS, IT COULD BE A SUITABLE INTERVENTION IN CARDIAC REHABILITATION PROGRAMS.	2007	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
20 1759  26 POSITIVE EFFECT OF YOGA ON CARDIORESPIRATORY FITNESS: A PILOT STUDY. INTRODUCTION: CARDIOVASCULAR DISEASE (CVD) IS THE LEADING CAUSE OF DEATH IN DEVELOPED COUNTRIES. AN INTEGRAL PART OF PRIMARY PREVENTION IS PHYSICAL ACTIVITY. ONE FORM OF PHYSICAL ACTIVITY TO BE POTENTIALLY USED IS YOGA, BUT THIS ACTIVITY IS ASSOCIATED WITH LOWER ENERGY EXPENDITURE THAN THAT RECOMMENDED FOR PREVENTION. THE STUDY AIMED AT ASSESSING THE EFFECT OF REGULAR YOGA SESSIONS ON THE AEROBIC CAPACITY OF THE PRACTITIONERS AND COMPARING IT WITH THE NORMAL POPULATION PERFORMING PHYSICAL ACTIVITY RECOMMENDED BY GUIDELINES. MATERIALS AND METHODS: FIFTY-EIGHT PERSONS (16 MALES) WITH A MEAN AGE OF 50.0 +/- 11.06 YEARS COMPRISING THE YOGA GROUP PRACTICED YOGA FOR AT LEAST 1 H A DAY FOR OVER 2 YEARS. THEY UNDERWENT SPIROERGOMETRY UNDER MAXIMAL EXERCISE TESTING TO ASSESS BASIC PERFORMANCE PARAMETERS. THEIR RESULTS WERE COMPARED WITH THOSE IN 54 AGE-MATCHED CONTROLS (16 MALES MEAN AGE OF 48 +/- 11.86 YEARS PERFORMING A REGULAR AEROBIC PHYSICAL ACTIVITY FOR AT LEAST 7 H A WEEK. RESULTS: THE YOGA GROUP HAD STATISTICALLY SIGNIFICANTLY HIGHER MAXIMUM PERFORMANCE PER KILOGRAM (P = 0.007) AND MAXIMUM OXYGEN CONSUMPTION PER KILOGRAM PER MINUTE (P = 0.028). CONCLUSIONS: DESPITE LOW ENERGY EXPENDITURE, YOGA PRACTICES ARE BETTER IN SOME CARDIORESPIRATORY FITNESS PARAMETERS THAN OTHER AEROBIC ACTIVITIES RECOMMENDED BY CURRENT GUIDELINES FOR CVD PREVENTION.	2015
