1 993 50 EFFECTS OF HEATED AND THERMONEUTRAL YOGA INTERVENTIONS ON ARTERIAL STIFFNESS IN MIDDLE-AGED ADULTS. THE STUDY INVESTIGATED THE EFFICACY OF 12 WEEKS OF HEATED AND THERMONEUTRAL BIKRAM YOGA IN REDUCING ARTERIAL STIFFNESS IN MIDDLE-AGED ADULTS. FIFTY-FOUR SEDENTARY ADULTS (AGES 40-60 YEARS) COMPLETED 12 WEEKS OF YOGA AT 40.5 DEGREES C (N = 21), YOGA AT 23 DEGREES C (N = 14) OR TIME CONTROL (N = 19). BRACHIAL-ANKLE PULSE WAVE VELOCITY (PWV) WAS NOT SIGNIFICANTLY ALTERED BY HOT OR THERMONEUTRAL YOGA INTERVENTIONS. 2018
2 2076 22 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
3 1045 36 EFFECTS OF YOGA INTERVENTIONS PRACTISED IN HEATED AND THERMONEUTRAL CONDITIONS ON ENDOTHELIUM-DEPENDENT VASODILATATION: THE BIKRAM YOGA HEART STUDY. NEW FINDINGS: WHAT IS THE CENTRAL QUESTION OF THIS STUDY? DOES THE HEATED PRACTICE ENVIRONMENT ENHANCE THE EFFECTS OF BIKRAM YOGA ON ENDOTHELIUM-DEPENDENT VASODILATATION IN HEALTHY, MIDDLE-AGED ADULTS? WHAT IS THE MAIN FINDING AND ITS IMPORTANCE? THE PRIMARY FINDING FROM THIS INVESTIGATION IS THAT THE HATHA YOGA POSTURES IN THE BIKRAM YOGA SERIES PRODUCE SIMILAR ENHANCEMENTS IN ENDOTHELIUM-DEPENDENT VASODILATATION IN HEALTHY, MIDDLE-AGED ADULTS REGARDLESS OF ENVIRONMENTAL TEMPERATURE. THESE FINDINGS HIGHLIGHT THE EFFICACY OF YOGA POSTURES IN PRODUCING IMPROVEMENTS IN VASCULAR HEALTH AND DOWNPLAY THE NECESSITY OF THE HEATED PRACTICE ENVIRONMENT IN INDUCING VASCULAR ADAPTATIONS. ABSTRACT: WE HAVE PREVIOUSLY DOCUMENTED IMPROVEMENTS IN ENDOTHELIUM-DEPENDENT VASODILATATION WITH A BIKRAM (HOT) YOGA INTERVENTION IN MIDDLE-AGED ADULTS. AT PRESENT, THE EFFECT OF ENVIRONMENTAL TEMPERATURE IN HOT YOGA ON ENDOTHELIAL FUNCTION IS UNKNOWN. THE PURPOSE OF THIS INVESTIGATION WAS TO DETERMINE THE EFFECTS OF BIKRAM YOGA INTERVENTIONS PERFORMED IN HEATED OR THERMONEUTRAL CONDITIONS ON ENDOTHELIUM-DEPENDENT VASODILATATION. FIFTY-TWO SEDENTARY BUT APPARENTLY HEALTHY ADULTS AGED 40-60 YEARS WERE RANDOMLY ASSIGNED TO ONE OF THREE GROUPS: BIKRAM YOGA PRACTISED AT 40.5 DEGREES C (N = 19), BIKRAM YOGA PRACTISED AT 23 DEGREES C (N = 14) OR SEDENTARY TIME CONTROL (N = 19). THE YOGA INTERVENTIONS CONSISTED OF 90 MIN BIKRAM YOGA CLASSES THREE TIMES A WEEK FOR 12 WEEKS. ENDOTHELIUM-DEPENDENT VASODILATATION WAS MEASURED NON-INVASIVELY USING BRACHIAL ARTERY FLOW-MEDIATED DILATATION (FMD). BODY FAT PERCENTAGE DETERMINED VIA DUAL-ENERGY X-RAY ABSORPTIOMETRY WAS SIGNIFICANTLY LOWER IN THE HOT YOGA GROUP AFTER THE INTERVENTION THAN IN THE THERMONEUTRAL YOGA AND CONTROL CONDITIONS. BRACHIAL ARTERY FMD INCREASED (P < 0.05) IN THE THERMONEUTRAL YOGA GROUP AND TENDED TO INCREASE IN THE HOT YOGA GROUP (P = 0.056). NO CHANGES OCCURRED IN THE CONTROL GROUP. THERE WERE NO SIGNIFICANT DIFFERENCES IN FMD CHANGE SCORES BETWEEN GROUPS. WE CONCLUDE THAT BIKRAM YOGA PRACTISED IN THERMONEUTRAL CONDITIONS IMPROVED ENDOTHELIUM-DEPENDENT VASODILATATION IN HEALTHY, MIDDLE-AGED ADULTS. THESE NEW FINDINGS HIGHLIGHT THE EFFECTIVENESS OF HATHA YOGA POSTURES ALONE, IN THE ABSENCE OF A HEATED PRACTICE ENVIRONMENT, IN IMPROVING VASCULAR HEALTH AND ARE OF CLINICAL SIGNIFICANCE GIVEN THE INCREASED PROPENSITY FOR HEAT INTOLERANCE IN AGEING ADULTS. 2018
4 1298 19 HATHA YOGA AND VASCULAR FUNCTION: RESULTS FROM CROSS-SECTIONAL AND INTERVENTIONAL STUDIES. THE AIM OF THIS STUDY WAS TO DETERMINE THE EFFECT OF HATHA YOGA ON ARTERIAL ELASTICITY AND ENDOTHELIAL FUNCTION. FIRST, A CROSS-SECTIONAL STUDY WAS PERFORMED TO DETERMINE WHETHER YOGA PRACTITIONERS WOULD DEMONSTRATE GREATER ARTERIAL COMPLIANCE AND ENDOTHELIUM-DEPENDENT VASODILATION THAN THEIR SEDENTARY PEERS. SECOND, AN INTERVENTION STUDY INVOLVING 13 SEDENTARY MIDDLE-AGED AND OLDER ADULTS (51 +/- 7 YEARS) WAS PERFORMED TO DETERMINE WHETHER 12 WEEKS OF HATHA YOGA WOULD ELICIT INCREASES IN ARTERIAL COMPLIANCE AND ENDOTHELIAL FUNCTION. IN THE CROSS-SECTIONAL STUDY INVOLVING A TOTAL OF 34 SUBJECTS, THERE WERE NO GROUP DIFFERENCES IN BODY FATNESS, BLOOD LIPID AND LIPOPROTEIN CONCENTRATIONS, CAROTID ARTERY COMPLIANCE OR BRACHIAL ARTERY FLOW-MEDIATED DILATION (FMD). HEMOGLOBIN A1C WAS LOWER IN YOGA PRACTITIONERS THAN IN SEDENTARY ADULTS (P < 0.05). TOTAL CHOLESTEROL AND HEMOGLOBIN A1C DECREASED AFTER THE INTERVENTION (P < 0.05) WHILE CAROTID ARTERY COMPLIANCE AND BRACHIAL ARTERY FMD DID NOT CHANGE. THE RESULTS OF BOTH CROSS-SECTIONAL AND INTERVENTIONAL STUDIES INDICATE THAT REGULAR PRACTICE OF HATHA YOGA IS NOT ASSOCIATED WITH IMPROVEMENTS IN VASCULAR FUNCTIONS. 2013
5 2075 26 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
6 2778 13 YOGA STRETCHING FOR IMPROVING SALIVARY IMMUNE FUNCTION AND MENTAL STRESS IN MIDDLE-AGED AND OLDER ADULTS. PROTECTION AGAINST AGE-RELATED IMMUNE SUPPRESSION IS IMPORTANT IN ELDERLY INDIVIDUALS. THIS STUDY DETERMINED THE EFFECT OF YOGA ON MUCOSAL IMMUNE FUNCTION AND MENTAL STRESS. SALIVA SAMPLES WERE COLLECTED FROM 23 ADULT WOMEN (AGE: 60.4 +/- 10.4 YEARS) BEFORE AND AFTER 90 MINUTES OF YOGA STRETCHING OR REST TO MEASURE SECRETORY IMMUNOGLOBULIN A (SIGA), CORTISOL, AND TESTOSTERONE. THE SIGA CONCENTRATION AND SECRETION RATE WERE SIGNIFICANTLY HIGHER AFTER YOGA THAN BEFORE (P < .05). THE CORTISOL CONCENTRATION AND SECRETION RATE WERE LOWER AND TESTOSTERONE SECRETION RATE HIGHER AFTER YOGA (P < .05). YOGA STRETCHING CAN REDUCE STRESS AND ENHANCE MUCOSAL IMMUNE FUNCTION IN ELDERLY WOMEN. 2018
7 1377 24 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
8 2242 20 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
9 1933 12 ROLE OF YOGA IN MODIFYING CERTAIN CARDIOVASCULAR FUNCTIONS IN TYPE 2 DIABETIC PATIENTS. OBJECTIVES: 1. TO STUDY THE EFFECT OF FORTY DAYS OF YOGIC EXERCISES ON CARDIAC FUNCTIONS IN TYPE 2 DIABETICS. 2. TO STUDY THE EFFECT OF FORTY DAYS OF YOGIC EXERCISES ON BLOOD GLUCOSE LEVEL, GLYCOSYLATED HEMOGLOBIN. METHODS: THE PRESENT STUDY DONE IN TWENTY-FOUR TYPE 2 DM CASES PROVIDES METABOLIC AND CLINICAL EVIDENCE OF IMPROVEMENT IN GLYCAEMIC CONTROL AND AUTONOMIC FUNCTIONS. THESE MIDDLE-AGED SUBJECTS WERE TYPE II DIABETICS ON ANTIHYPERGLYCAEMIC AND DIETARY REGIMEN. THEIR BASELINE FASTING AND POSTPRANDIAL BLOOD GLUCOSE AND GLYCOSYLATED HB WERE MONITORED ALONG WITH AUTONOMIC FUNCTION STUDIES. THE EXPERT GAVE THESE PATIENTS TRAINING IN YOGA ASANAS AND THEY PURSUED THOSE 30-40 MIN/DAY FOR 40 DAYS UNDER GUIDANCE. THESE ASANAS CONSISTED OF 13 WELL KNOWN POSTURES, DONE IN A SEQUENCE. AFTER 40 DAYS OF YOGA ASANAS REGIMEN, THE PARAMETERS WERE REPEATED. RESULTS: THE RESULTS INDICATE THAT THERE WAS SIGNIFICANT DECREASE IN FASTING BLOOD GLUCOSE LEVELS FROM BASAL 190.08 +/- 18.54 IN MG/DL TO 141.5 +/- 16.3 IN MG/DL AFTER YOGA REGIMEN. THE POST PRANDIAL BLOOD GLUCOSE LEVELS DECREASED FROM 276.54 +/- 20.62 IN MG/DL TO 201.75 +/- 21.24 IN MG/DL, GLYCOSYLATED HEMOGLOBIN SHOWED A DECREASE FROM 9.03 +/- 0.29% TO 7.83 +/- 0.53% AFTER YOGA REGIMEN. THE PULSE RATE, SYSTOLIC AND DIASTOLIC BLOOD PRESSURE DECREASED SIGNIFICANTLY (FROM 86.45 +/- 2.0 TO 77.65 +/- 2.5 PULSE/MIN, FROM 142.0 +/- 3.9 TO 126.0 +/- 3.2 MM OF HG AND FROM 86.7 +/- 2.5 MM OF HG TO 75.5 +/- 2.1 MM OF HG AFTER YOGA REGIMEN RESPECTIVELY). CORRECTED QT INTERVAL (QTC) DECREASED FROM 0.42 +/- 0.0 TO 0.40 +/- 0.0. CONCLUSION: THESE FINDINGS SUGGEST THAT BETTER GLYCAEMIC CONTROL AND STABLE AUTONOMIC FUNCTIONS CAN BE OBTAINED IN TYPE 2 DM CASES WITH YOGA ASANAS AND PRANAYAMA. THE EXACT MECHANISM AS TO HOW THESE POSTURES AND CONTROLLED BREATHING INTERACT WITH SOMATO-NEURO-ENDOCRINE MECHANISM AFFECTING METABOLIC AND AUTONOMIC FUNCTIONS REMAINS TO BE WORKED OUT. 2004
10 2131 15 THE EFFECTS OF A 6-MONTH MODERATE-INTENSITY HATHA YOGA-BASED TRAINING PROGRAM ON HEALTH-RELATED FITNESS IN MIDDLE-AGED SEDENTARY WOMEN: A RANDOMIZED CONTROLLED STUDY. BACKGROUND: THERE IS PAUCITY OF DATA EXAMINING THE EFFECTIVENESS OF LONG-TERM HATHA YOGA-BASED (HY) PROGRAMS FOCUSED ON THE HEALTH-RELATED FITNESS (H-RF) OF ASYMPTOMATIC, SEDENTARY WOMEN. THE PURPOSE OF THIS STUDY WAS TO EXAMINE THE EFFECTS OF A 6-MONTH HY-BASED TRAINING PROGRAM ON H-RF COMPONENTS IN SEDENTARY MIDDLE-AGED WOMEN. METHODS: EIGHTY SEDENTARY WOMEN WERE RANDOMLY ASSIGNED INTO EITHER THE HY GROUP (HYG) (N.=42) OR THE CONTROL GROUP (CG) (N.=38). THE 6-MONTH HYG PROGRAM INVOLVED A PROGRESSIVE SERIES OF VINYASA FLOW POSES PERFORMED 3 TIMES/WEEK FOR 60 MINUTES (40 MINUTES WITHIN THE EXERCISE ZONE OF 60-75% HRMAX). THE CG PARTICIPANTS DID NOT UNDERGO ANY PHYSICAL TRAINING OR EDUCATION. HEALTH-RELATED FITNESS PARAMETERS INCLUDED MEASURES OF PRE- AND POST-TRAINING: BODY COMPOSITION, MUSCULAR STRENGTH AND MAXIMAL VOLUNTARY ISOMETRIC TORQUES OF ELBOW FLEXORS AND KNEE EXTENSORS, CARDIO-RESPIRATORY FITNESS, LOWER BACK AND HAMSTRING FLEXIBILITY AND A STATIC-DYNAMIC BALANCE. RESULTS: TWO-WAY MIXED DESIGN ANOVA REVEALED SIGNIFICANT MAIN EFFECTS FOR ALL THE INDICATORS OF H-RF. TUKEY POST-HOC TESTS CONFIRMED THAT THE HYG DEMONSTRATED SIGNIFICANT IMPROVEMENTS IN EVERY VARIABLE TESTED. EXAMPLES OF THE BENEFITS ACHIEVED INCLUDE (ALL P<.001): AN AVERAGE LOSS OF 1.03 KG AND A 4.82% DECREASE IN BODY FAT, 14.6% AND 13.1% GAINS IN ISOMETRIC STRENGTH OF THE KNEE EXTENSORS AND ELBOW FLEXORS RESPECTIVELY, AN INCREASE IN RELATIVE VO2MAX OF 6.1% (33.12+/-5.30 TO 35.14+/-4.82 ML/KG/MIN), A 4-CM OR 10.4% INCREASE IN THEIR MSAR, AND AN AVERAGE IMPROVED BALANCE INDEX OF 5.6 MM/S. REVERSELY, THE CG SHOWED NON-SIGNIFICANT CHANGES IN H-RF VARIABLES (ALL P>0.05; PERCENT RANGE FROM -1.4% TO 1.1%). CONCLUSIONS: BY PARTICIPATING IN A MODERATE-INTENSITY 6-MONTH HY-BASED TRAINING PROGRAM, MIDDLE-AGED WOMEN CAN SIGNIFICANTLY IMPROVE THEIR HR-F STATUS. THE APPLICATION OF PROGRESSIVE TARGET HEART RATE GOALS FACILITATED GREATER THAN EXPECTED IMPROVEMENTS IN CARDIO-RESPIRATORY FITNESS AND IMPROVEMENTS IN BODY COMPOSITION. 2020
11 700 8 EFFECT OF HIGH TEMPERATURE YOGA EXERCISE ON IMPROVING PHYSICAL AND MENTAL WELL-BEING OF OVERWEIGHT MIDDLE-AGED AND YOUNG WOMEN. OBJECTIVE: TO EXPLORE THE EFFECT OF HIGH TEMPERATURE YOGA EXERCISE ON IMPROVING PHYSICAL AND PSYCHOLOGICAL WELL-BEING OF OVERWEIGHT MIDDLE-AGED AND YOUNG WOMEN. DESIGN: 50 OVERWEIGHT MIDDLE-AGED AND YOUNG WOMEN FROM YOGA CLUBS WERE SELECTED. THE INDEXES OF THEIR CONSTITUTION, PHYSIOLOGICAL FUNCTIONS, PSYCHOLOGICAL ADAPTATION WERE MEASURED AND COMPARED BEFORE AND AFTER ONE YEAR OF UNINTERRUPTED HIGH TEMPERATURE YOGA EXERCISE. RESULTS: THE INDEXES OF THE SUBJECTS' CONSTITUTION AND PHYSIOLOGICAL FUNCTIONS WERE REMARKABLY UPLIFTED (P < 0.05); THEIR PSYCHOLOGICAL ADAPTATION WAS IMPROVED AS WELL. CONCLUSION: AEROBICS REPRESENTED BY HIGH TEMPERATURE YOGA CAN IMPROVE BODY SHAPE, LOWER LIPID, REDUCE WEIGHT, AND EXERT AN EVIDENT THERAPEUTIC EFFECT ON IMPROVING PHYSIOLOGICAL FUNCTIONS AND BOOSTING PSYCHOLOGICAL WELL-BEING. 2014
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
13 404 18 BIKRAM YOGA TRAINING AND PHYSICAL FITNESS IN HEALTHY YOUNG ADULTS. THERE HAS BEEN RELATIVELY LITTLE LONGITUDINAL CONTROLLED INVESTIGATION OF THE EFFECTS OF YOGA ON GENERAL PHYSICAL FITNESS, DESPITE THE WIDESPREAD PARTICIPATION IN THIS FORM OF EXERCISE. THE PURPOSE OF THIS EXPLORATORY STUDY WAS TO EXAMINE THE EFFECT OF SHORT-TERM BIKRAM YOGA TRAINING ON GENERAL PHYSICAL FITNESS. YOUNG HEALTHY ADULTS WERE RANDOMIZED TO YOGA TRAINING (N = 10, 29 +/- 6 YEARS, 24 SESSIONS IN 8 WEEKS) OR A CONTROL GROUP (N = 11, 26 +/- 7 YEARS). EACH YOGA TRAINING SESSION CONSISTED OF 90-MINUTE STANDARDIZED SUPERVISED POSTURES PERFORMED IN A HEATED AND HUMIDIFIED STUDIO. ISOMETRIC DEADLIFT STRENGTH, HANDGRIP STRENGTH, LOWER BACK/HAMSTRING AND SHOULDER FLEXIBILITY, RESTING HEART RATE AND BLOOD PRESSURE, MAXIMAL OXYGEN CONSUMPTION (TREADMILL), AND LEAN AND FAT MASS (DUAL-ENERGY X-RAY ABSORPTIOMETRY) WERE MEASURED BEFORE AND AFTER TRAINING. YOGA SUBJECTS EXHIBITED INCREASED DEADLIFT STRENGTH, SUBSTANTIALLY INCREASED LOWER BACK/HAMSTRING FLEXIBILITY, INCREASED SHOULDER FLEXIBILITY, AND MODESTLY DECREASED BODY FAT COMPARED WITH CONTROL GROUP. THERE WERE NO CHANGES IN HANDGRIP STRENGTH, CARDIOVASCULAR MEASURES, OR MAXIMAL AEROBIC FITNESS. IN SUMMARY, THIS SHORT-TERM YOGA TRAINING PROTOCOL PRODUCED BENEFICIAL CHANGES IN MUSCULOSKELETAL FITNESS THAT WERE SPECIFIC TO THE TRAINING STIMULUS. 2013
14 968 19 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
15 2007 13 STUDY OF YOGA ASANAS IN ASSESSMENT OF PULMONARY FUNCTION IN NIDDM PATIENTS. CERTAIN YOGA ASANAS IF PRACTICED REGULARLY ARE KNOWN TO HAVE BENEFICIAL EFFECTS ON HUMAN BODY. THESE YOGA PRACTICES MIGHT BE INTERACTING WITH VARIOUS, SOMATO-NEURO-ENDOCRINE MECHANISMS TO HAVE THERAPEUTIC EFFECTS. THE PRESENT STUDY DONE IN TWENTY FOUR NIDDM PATIENTS OF 30 TO 60 YEAR OLD, PROVIDES METABOLIC AND CLINICAL EVIDENCE OF IMPROVEMENT IN GLYCAEMIC CONTROL AND PULMONARY FUNCTIONS. THESE MIDDLE-AGED SUBJECTS WERE TYPE II DIABETICS ON ANTIHYPERGLYCAEMIC AND DIETARY REGIMEN. THEIR BASELINE FASTING AND POSTPRANDIAL BLOOD GLUCOSE AND GLYCOSYLATED HB WERE MONITORED ALONG WITH PULMONARY FUNCTION STUDIES. THE EXPERT GAVE THESE PATIENTS TRAINING IN YOGA ASANAS AND WERE PURSED 30-40 MIN/DAY FOR 40 DAYS UNDER GUIDANCE. THESE ASANAS CONSISTED OF 13 WELL KNOWN POSTURES, DONE IN A SEQUENCE. AFTER 40 DAYS OF YOGA ASANAS REGIMEN, THE PARAMETERS WERE REPEATED. THE RESULTS INDICATE THAT THERE WAS SIGNIFICANT DECREASE IN FASTING BLOOD GLUCOSE LEVELS (BASAL 190.08 +/- 90.8 IN MG/DL TO 141.5 +/- 79.8 IN MG/DL). THE POSTPRANDIAL BLOOD GLUCOSE LEVELS ALSO DECREASED (276.54 +/- 101.0 IN MG/DL TO 201.75 +/- 104.1 IN MG/DL), GLYCOSYLATED HEMOGLOBIN SHOWED A DECREASE (9.03 +/- 1.4% TO 7.83 +/- 2.6%). THE FEV1, FVC, PEFR, MVV INCREASED SIGNIFICANTLY (1.81 +/- 0.4 LT TO 2.08 +/- 0.4 LT, 2.20 +/- 0.6 LT TO 2.37 +/- 0.5 LT, 3.30 +/- 1.0 LT/S TO 4.43 +/- 1.4 LT/S AND 64.59 +/- 25.7 LT MIN TO 76.28 +/- 28.1 LT/MIN RESPECTIVELY). FEV1/FVC% IMPROVED (85 +/- 0.2% TO 89 +/- 0.1%). THESE FINDINGS SUGGEST THAT BETTER GLYCAEMIC CONTROL AND PULMONARY FUNCTIONS CAN BE OBTAINED IN NIDDM CASES WITH YOGA ASANAS AND PRANAYAMA. THE EXACT MECHANISM AS TO HOW THESE POSTURES AND CONTROLLED BREATHING, INTERACT WITH SOMATO-NEURO-ENDOCRINE MECHANISM AFFECTING METABOLIC AND PULMONARY FUNCTIONS REMAINS TO BE WORKED OUT. 2002
16 437 12 CARDIOVASCULAR AND METABOLIC EFFECTS OF INTENSIVE HATHA YOGA TRAINING IN MIDDLE-AGED AND OLDER WOMEN FROM NORTHERN MEXICO. BACKGROUND: HATHA YOGA (HY) CAN BE AN ALTERNATIVE TO IMPROVE PHYSICAL ACTIVITY IN MIDDLE-AGED AND OLDER WOMEN. HOWEVER, CONVENTIONAL HY (CHY) EXERCISING MAY NOT RESULT IN ENOUGH TRAINING STIMULUS TO IMPROVE CARDIOVASCULAR FITNESS. THE PURPOSE OF THIS STUDY WAS TO EVALUATE THE EFFECT OF AN INTENSIVE HY INTERVENTION (IHY) ON CARDIOVASCULAR RISK FACTORS IN MIDDLE-AGED AND OLDER WOMEN FROM NORTHERN MEXICO. MATERIALS AND METHODS: IN THIS PROSPECTIVE QUASIEXPERIMENTAL DESIGN, FOUR MIDDLE-AGED AND NINE OLDER CHY PRACTICING FEMALES (YOGINIS) WERE ENROLLED INTO AN 11-WEEK IHY PROGRAM CONSISTING OF 5 SESSIONS/WEEK FOR 90 MIN (55 SESSIONS). THE PROGRAM ADHERENCE, ASANA PERFORMANCE, AND WORK INTENSITY WERE ASSESSED ALONG THE INTERVENTION. ANTHROPOMETRIC [BODY MASS INDEX (BMI), % BODY FAT AND SIGMA SKIN FOLDS], CARDIOVASCULAR FITNESS [MAXIMAL EXPIRED AIR VOLUME (VE(MAX)), MAXIMAL O(2) CONSUMPTION (VO(2MAX)), MAXIMAL HEART RATE (HR(MAX)), SYSTOLIC (BPS) AND DIASTOLIC BLOOD PRESSURE (BPD)], BIOCHEMICAL [GLUCOSE, TRIACYLGLYCEROLS (TAG), TOTAL CHOLESTEROL (TC), HIGH-DENSITY LIPOPROTEIN CHOLESTEROL (HDL-C), AND LOW-DENSITY LIPOPROTEIN CHOLESTEROL (LDL-C)], AND DIETARY PARAMETERS WERE EVALUATED BEFORE AND AFTER IHY. RESULTS: DAILY CALORIC INTAKE (~1,916 KCAL/DAY), PROGRAM ADHERENCE (~85%), AND EXERCISING SKILLS (ASANA PERFORMANCE) WERE SIMILAR IN BOTH MIDDLE-AGED AND OLDER WOMEN. THE IHY PROGRAM DID NOT MODIFY ANY ANTHROPOMETRIC MEASUREMENTS. HOWEVER, IT INCREASED VO(2MAX) AND VE(MAX) AND HDL-C WHILE TAG AND LDL-C REMAINED STABLE IN BOTH MIDDLE-AGED AND OLDER GROUPS (P < 0.01). CONCLUSIONS: THE PROPOSED IHY PROGRAM IMPROVES DIFFERENT CARDIOVASCULAR RISK FACTORS (NAMELY VO(2MAX) AND HDL-C) IN MIDDLE-AGED AND OLDER WOMEN. 2009
17 1340 15 HOW IS THE PRACTICE OF YOGA RELATED TO WEIGHT STATUS? POPULATION-BASED FINDINGS FROM PROJECT EAT-IV. BACKGROUND: YOGA MAY PROVIDE A STRATEGY FOR HEALTHY WEIGHT MANAGEMENT IN YOUNG ADULTS. THIS STUDY EXAMINED PREVALENCE AND CHARACTERISTICS OF YOUNG ADULTS' YOGA PRACTICE AND ASSOCIATIONS WITH CHANGES IN BODY MASS INDEX. METHODS: SURVEYS WERE COMPLETED BY 1830 YOUNG ADULTS (31.1 +/- 1.6 Y) PARTICIPATING IN PROJECT EAT-IV. CROSS-SECTIONAL AND 5-YEAR LONGITUDINAL ANALYSES WERE CONDUCTED STRATIFIED BY INITIAL WEIGHT STATUS. RESULTS: TWO-THIRDS (66.5%) OF NONOVERWEIGHT WOMEN AND 48.9% OF OVERWEIGHT WOMEN REPORTED EVER DOING YOGA, WHILE 27.2% OF NONOVERWEIGHT WOMEN AND 16.4% OF OVERWEIGHT WOMEN PRACTICED REGULARLY (>/=30 MIN/WK). FEWER MEN PRACTICED YOGA. AMONG YOUNG ADULTS PRACTICING REGULARLY (N = 294), DIFFERENCES WERE IDENTIFIED IN INTENSITY, TYPE, AND LOCATION OF YOGA PRACTICE ACROSS WEIGHT STATUS. YOUNG ADULTS WHO WERE OVERWEIGHT AND PRACTICED YOGA REGULARLY SHOWED A NONSIGNIFICANT 5-YEAR DECREASE IN THEIR BODY MASS INDEX (-0.60 KG/M(2); P = .49), WHEREAS THOSE NOT PRACTICING REGULARLY HAD SIGNIFICANT INCREASES IN THEIR BODY MASS INDEX (+1.37 KG/M(2); P < .01). FREQUENCY OF YOGA WAS INVERSELY ASSOCIATED WITH WEIGHT GAIN AMONG BOTH OVERWEIGHT AND NONOVERWEIGHT YOUNG ADULTS PRACTICING YOGA REGULARLY. CONCLUSIONS: YOUNG ADULTS OF DIFFERENT BODY SIZES PRACTICE YOGA. YOGA WAS ASSOCIATED WITH LESS WEIGHT GAIN OVER TIME, PARTICULARLY IN OVERWEIGHT YOUNG ADULTS. PRACTICING YOGA ON A REGULAR BASIS MAY HELP WITH WEIGHT GAIN PREVENTION. 2017
18 74 19 A GROUP-BASED YOGA THERAPY INTERVENTION FOR URINARY INCONTINENCE IN WOMEN: A PILOT RANDOMIZED TRIAL. OBJECTIVE: THE AIM OF THIS STUDY IS TO EXAMINE THE FEASIBILITY, EFFICACY, AND SAFETY OF A GROUP-BASED YOGA THERAPY INTERVENTION FOR MIDDLE-AGED AND OLDER WOMEN WITH URINARY INCONTINENCE. METHODS: WE CONDUCTED A PILOT RANDOMIZED TRIAL OF AMBULATORY WOMEN AGED 40 YEARS AND OLDER WITH STRESS, URGENCY, OR MIXED-TYPE INCONTINENCE. WOMEN WERE RANDOMIZED TO A 6-WEEK YOGA THERAPY PROGRAM (N = 10) CONSISTING OF TWICE WEEKLY GROUP CLASSES AND ONCE WEEKLY HOME PRACTICE OR A WAIT-LIST CONTROL GROUP (N = 9). ALL PARTICIPANTS ALSO RECEIVED WRITTEN PAMPHLETS ABOUT STANDARD BEHAVIORAL SELF-MANAGEMENT STRATEGIES FOR INCONTINENCE. CHANGES IN INCONTINENCE WERE ASSESSED WITH 7-DAY VOIDING DIARIES. RESULTS: THE MEAN (SD) AGE WAS 61.4 (8.2) YEARS, AND THE MEAN BASELINE FREQUENCY OF INCONTINENCE WAS 2.5 (1.3) EPISODES/D. AFTER 6 WEEKS, THE TOTAL INCONTINENCE FREQUENCY DECREASED BY 70% (1.8 [0.9] FEWER EPISODES/D) IN THE YOGA THERAPY VERSUS 13% (0.3 [1.7] FEWER EPISODES/D) IN THE CONTROL GROUP (P = 0.049). PARTICIPANTS IN THE YOGA THERAPY GROUP ALSO REPORTED AN AVERAGE OF 71% DECREASE IN STRESS INCONTINENCE FREQUENCY (0.7 [0.8] FEWER EPISODES/D) COMPARED WITH A 25% INCREASE IN CONTROLS (0.2 [1.1] MORE EPISODES/D) (P = 0.039). NO SIGNIFICANT DIFFERENCES IN REDUCTION IN URGENCY INCONTINENCE WERE DETECTED BETWEEN THE YOGA THERAPY VERSUS CONTROL GROUPS (1.0 [1.0] VERSUS 0.5 [0.5] FEWER EPISODES/D; P = 0.20). ALL WOMEN STARTING THE YOGA THERAPY PROGRAM COMPLETED AT LEAST 90% OF THE GROUP CLASSES AND PRACTICE SESSIONS. TWO PARTICIPANTS IN EACH GROUP REPORTED ADVERSE EVENTS UNRELATED TO THE INTERVENTION. CONCLUSIONS: FINDINGS PROVIDE PRELIMINARY EVIDENCE TO SUPPORT THE FEASIBILITY, EFFICACY, AND SAFETY OF A GROUP-BASED YOGA THERAPY INTERVENTION TO IMPROVE URINARY INCONTINENCE IN WOMEN. 2014
19 2751 16 YOGA PRACTICE IS ASSOCIATED WITH ATTENUATED WEIGHT GAIN IN HEALTHY, MIDDLE-AGED MEN AND WOMEN. BACKGROUND: YOGA IS PROMOTED OR WEIGHT MAINTENANCE, BUT THERE IS LITTLE EVIDENCE OF ITS EFFICACY. OBJECTIVE: TO EXAMINE WHETHER YOGA PRACTICE IS ASSOCIATED WITH LOWER MEAN 10-YEAR WEIGHT GAIN AFTER AGE 45. PARTICIPANTS: PARTICIPANTS INCLUDED 15,550 ADULTS, AGED 53 TO 57 YEARS, RECRUITED TO THE VITAMIN AND LIFESTYLE (VITAL) COHORT STUDY BETWEEN 2000 AND 2002. MEASUREMENTS: PHYSICAL ACTIVITY (INCLUDING YOGA) DURING THE PAST 10 YEARS, DIET, HEIGHT, AND WEIGHT AT RECRUITMENT AND AT AGES 30 AND 45. ALL MEASURES WERE BASED ON SELF-REPORTING, AND PAST WEIGHT WAS RETROSPECTIVELY ASCERTAINED. METHODS: MULTIPLE REGRESSION ANALYSES WERE USED TO EXAMINED COVARIATE-ADJUSTED ASSOCIATIONS BETWEEN YOGA PRACTICE AND WEIGHT CHANGE FROM AGE 45 TO RECRUITMENT, AND POLYCHOTOMOUS LOGISTIC REGRESSION WAS USED TO EXAMINE ASSOCIATIONS OF YOGA PRACTICE WITH THE RELATIVE ODDS OF WEIGHT MAINTENANCE (WITHIN 5%) AND WEIGHT LOSS (> 5%) COMPARED TO WEIGHT GAIN. RESULTS: YOGA PRACTICE FOR FOUR OR MORE YEARS WAS ASSOCIATED WITH A 3.1-LB LOWER WEIGHT GAIN AMONG NORMAL WEIGHT (BMI < 25) PARTICIPANTS [9.5 LBS VERSUS 12.6 IBS] AND AN 18.5-LB LOWER WEIGHT GAIN AMONG OVERWEIGHT PARTICIPANTS [-5.0 LBS VERSUS 13.5 IBS] (BOTH P FOR TREND <.001). AMONG OVERWEIGHT INDIVIDUALS, 4+ YEARS OF YOGA PRACTICE WAS ASSOCIATED WITH A RELATIVE ODDS OF 1.85 (95% CONFIDENCE INTERVAL [CI] 0.63-5.42) FOR WEIGHT MAINTENANCE (WITHIN 5%) AND 3.88 (95% CL 1.30-9.88) FOR WEIGHT LOSS (> 5%) COMPARED TO WEIGHT GAIN (P FOR TREND .026 AND .003, RESPECTIVELY). CONCLUSIONS: REGULAR YOGA PRACTICE WAS ASSOCIATED WITH ATTENUATED WEIGHT GAIN, MOST STRONGLY AMONG INDIVIDUALS WHO WERE OVERWEIGHT. ALTHOUGH CAUSAL INFERENCE FROM THIS OBSERVATIONAL STUDY IS NOT POSSIBLE, RESULTS ARE CONSISTENT WITH THE HYPOTHESIS THAT REGULAR YOGA PRACTICE CAN BENEFIT INDIVIDUALS WHO WISH TO MAINTAIN OR LOSE WEIGHT. 2005
20 2072 16 THE EFFECT OF A SIX-WEEK PROGRAM OF YOGA AND MEDITATION ON BRACHIAL ARTERY REACTIVITY: DO PSYCHOSOCIAL INTERVENTIONS AFFECT VASCULAR TONE? BACKGROUND: CHRONIC STRESS IS ESTIMATED TO INCREASE THE RISK OF CARDIOVASCULAR (CV) EVENTS TWO-FOLD. ALTHOUGH STRESS REDUCTION HAS BEEN LINKED TO A REDUCTION IN CV EVENTS, LITTLE IS KNOWN REGARDING ITS EXACT MECHANISM OF BENEFIT. HYPOTHESIS: YOGA AND MEDITATION WILL IMPROVE PARAMETERS OF ENDOTHELIAL FUNCTION. METHODS: WE EXAMINED THE EFFECTS OF YOGA AND MEDITATION ON HEMODYNAMIC AND LABORATORY PARAMETERS AS WELL AS ON ENDOTHELIAL FUNCTION IN A 6-WEEK PILOT STUDY. SYSTOLIC AND DIASTOLIC BLOOD PRESSURES, HEART RATE, BODY MASS INDEX (BMI), FASTING GLUCOSE, LIPIDS, HS C-REACTIVE PROTEIN (CRP), AND ENDOTHELIAL FUNCTION (AS ASSESSED BY BRACHIAL ARTERY REACTIVITY) WERE ALL STUDIED AT BASELINE AND AFTER 6 WEEKS OF YOGA PRACTICE. RESULTS: A COURSE IN YOGA AND MEDITATION WAS GIVEN TO THE SUBJECTS FOR 1.5 H THREE TIMES WEEKLY FOR 6 WEEKS AND SUBJECTS WERE INSTRUCTED TO CONTINUE THEIR EFFORTS AT HOME. THIS PROSPECTIVE COHORT STUDY INCLUDED 33 SUBJECTS (MEAN AGE 55 +/- 11 YEARS) BOTH WITH (30%) AND WITHOUT (70%) ESTABLISHED CORONARY ARTERY DISEASE (CAD). THERE WERE SIGNIFICANT REDUCTIONS IN BLOOD PRESSURE, HEART RATE, AND BMI IN THE TOTAL COHORT WITH YOGA. NONE OF THE LABORATORY PARAMETERS CHANGED SIGNIFICANTLY WITH YOGA. FOR THE TOTAL COHORT THERE WAS NO SIGNIFICANT IMPROVEMENT IN ENDOTHELIAL-DEPENDENT VASODILATATION WITH YOGA TRAINING AND MEDITATION COMPARED WITH BASELINE (16.7% RELATIVE IMPROVEMENT FROM 7.2-8.4%; P = 0.3). IN THE GROUP WITH CAD, ENDOTHELIAL-DEPENDENT VASODILATATION IMPROVED 69% WITH YOGA TRAINING (6.38-10.78%; P = 0.09). CONCLUSION: YOGA AND MEDITATION APPEAR TO IMPROVE ENDOTHELIAL FUNCTION IN SUBJECTS WITH CAD. 2006
