1  425 140 CALCIUM LOSS IN SWEAT DOES NOT STIMULATE PTH RELEASE: A STUDY OF BIKRAM HOT YOGA. IT HAS BEEN HYPOTHESIZED THAT SWEAT LOSS DURING EXERCISE CAUSES A DISRUPTION IN CALCIUM HOMEOSTASIS THAT ACTIVATES BONE RESORPTION AND OVER TIME LEADS TO LOW BONE MINERAL DENSITY. THE PURPOSE OF THIS SMALL PILOT STUDY WAS TO DETERMINE WHETHER DERMAL CALCIUM LOSS FROM A BOUT OF EXCESSIVE SWEATING DURING LIGHT INTENSITY PHYSICAL ACTIVITY TRIGGERS AN INCREASE IN BIOMARKERS OF BONE RESORPTION. BIOCHEMICAL MARKERS RELATED TO BONE HOMEOSTASIS WERE MEASURED BEFORE AND AFTER A 90 MIN BIKRAM HOT YOGA PRACTICE PERFORMED IN A ROOM HEATED TO 105 DEGREES F WITH 40 % HUMIDITY. PARTICIPANTS WERE FIVE FEMALES WITH A MEAN AGE OF 47.4 +/- 4.7 YEARS. NUDE BODY WEIGHT, SERUM TOTAL CALCIUM (CA(2+)), FREE IONIZED CALCIUM, ALBUMIN, PARATHYROID HORMONE (PTH) AND CTX-I WERE MEASURED BEFORE AND AFTER A BIKRAM HOT YOGA PRACTICE. MEAN ESTIMATED SWEAT LOSS WAS 1.54 +/- 0.65 L, WHICH ELICITED A 1.9 +/- 0.9 % DECREASE IN PARTICIPANT'S BODY WEIGHT. MEAN CA(2+) CONCENTRATION IN SWEAT WAS 2.9 +/- 1.7 MG/DL AND THE ESTIMATED MEAN TOTAL CALCIUM LOST WAS 41.3 +/- 16.4 MG. SERUM IONIZED CA(2+) INCREASED FROM 4.76 +/- 0.29 MG/DL TO 5.35 +/- 0.36 MG/DL AFTER THE BIKRAM HOT YOGA PRACTICE (P = 0.0118). SERUM PTH DECREASED FROM PRE- 33.9 +/- 3.3 PG/ML TO POST- 29.9 +/- 2.1 PG/ML YOGA PRACTICE (P = 0.0015) WHEN ADJUSTED FOR HEMOCONCENTRATION (PTHADJ), IMPLYING A DECREASE IN PTH SECRETION. WE CONCLUDE THAT CALCIUM LOSS IN SWEAT DURING 90 MIN OF BIKRAM HOT YOGA DID NOT TRIGGER AN INCREASE IN PTH SECRETION AND DID NOT INITIATE BONE RESORPTION.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
2  968  44 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	

3 2333  20 TWELVE-MINUTE DAILY YOGA REGIMEN REVERSES OSTEOPOROTIC BONE LOSS. OBJECTIVE: ASSESS THE EFFECTIVENESS OF SELECTED YOGA POSTURES IN RAISING BONE MINERAL DENSITY (BMD). METHODS: TEN-YEAR STUDY OF 741 INTERNET-RECRUITED VOLUNTEERS COMPARING PREYOGA BMD CHANGES WITH POSTYOGA BMD CHANGES. OUTCOME MEASURES: DUAL-ENERGY X-RAY ABSORPTIOMETRIC SCANS. OPTIONAL RADIOGRAPHS OF HIPS AND SPINE AND BONE QUALITY STUDY (7 TESLA). RESULTS: BONE MINERAL DENSITY IMPROVED IN SPINE, HIPS, AND FEMUR OF THE 227 MODERATELY AND FULLY COMPLIANT PATIENTS. MONTHLY GAIN IN BMD WAS SIGNIFICANT IN SPINE (0.0029 G/CM(2), P = .005) AND FEMUR (0.00022 G/CM(2), P = .053), BUT IN 1 COHORT, ALTHOUGH MEAN GAIN IN HIP BMD WAS 50%, LARGE INDIVIDUAL DIFFERENCES RAISED THE CONFIDENCE INTERVAL AND THE GAIN WAS NOT SIGNIFICANT FOR TOTAL HIP (0.000357 G/CM(2)). NO YOGA-RELATED SERIOUS INJURIES WERE IMAGED OR REPORTED. BONE QUALITY APPEARED QUALITATIVELY IMPROVED IN YOGA PRACTITIONERS. CONCLUSION: YOGA APPEARS TO RAISE BMD IN THE SPINE AND THE FEMUR SAFELY.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
4 1944  59 SALT AND WATER BALANCE AFTER SWEAT LOSS: A STUDY OF BIKRAM YOGA. BIKRAM YOGA IS PRACTICED IN A ROOM HEATED TO 105 DEGREES F WITH 40% HUMIDITY FOR 90 MIN. DURING THE CLASS A LARGE VOLUME OF WATER AND ELECTROLYTES ARE LOST IN THE SWEAT, SPECIFICALLY, SODIUM IS LOST, THE MAIN CATION OF THE EXTRACELLULAR FLUID. THERE IS LITTLE KNOWN ABOUT THE VOLUME OF SWEAT AND THE AMOUNT OF SODIUM LOST IN SWEAT DURING BIKRAM YOGA OR THE OPTIMUM QUANTITY OF FLUID REQUIRED TO REPLACE THESE LOSSES. THE PARTICIPANTS WHO TOOK PART IN THIS SMALL FEASIBILITY STUDY WERE FIVE FEMALES WITH A MEAN AGE OF 47.4 +/- 4.7 YEARS AND 2.6 +/- 1.6 YEARS OF EXPERIENCE AT BIKRAM YOGA. THE TOTAL BODY WEIGHT, WATER CONSUMED, SERUM SODIUM CONCENTRATION, SERUM OSMOLALITY, AND SERUM ALDOSTERONE LEVELS WERE ALL MEASURED BEFORE AND AFTER A BIKRAM YOGA PRACTICE. SWEAT SODIUM CHLORIDE CONCENTRATION AND OSMOLALITY WERE MEASURED AT THE END OF THE PRACTICE. THE MEAN ESTIMATED SWEAT LOSS WAS 1.54 +/- 0.65 L, WHILE THE AMOUNT OF WATER CONSUMED DURING BIKRAM YOGA WAS 0.38 +/- 0.22 L. EVEN THOUGH ONLY 25% OF THE SWEAT LOSS WAS REPLENISHED WITH WATER INTAKE DURING THE BIKRAM YOGA CLASS, WE DID NOT OBSERVE A CHANGE IN SERUM SODIUM LEVELS OR SERUM OSMOLALITY. THE SWEAT CONTAINED 82 +/- 16 MMOL/L OF SODIUM CHLORIDE FOR AN ESTIMATED TOTAL OF 6.8 +/- 2.1 G OF SODIUM CHLORIDE LOST IN THE SWEAT. THE SERUM ALDOSTERONE INCREASED 3.5-FOLD FROM BEFORE TO AFTER BIKRAM YOGA. THERE WAS A DECREASE IN THE EXTRACELLULAR BODY FLUID COMPARTMENT OF 9.7%. SWEAT LOSS IN BIKRAM YOGA PREDOMINATELY PRODUCED A VOLUME DEPLETION RATHER THAN THE DEHYDRATION OF BODY FLUIDS. THE SWEATING-STIMULATED RISE IN SERUM ALDOSTERONE LEVELS WILL LEAD TO INCREASED SODIUM REABSORPTION FROM THE KIDNEY TUBULES AND RESTORE THE EXTRACELLULAR FLUID VOLUME OVER THE NEXT 24 HR.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
5 2160  27 THE EFFECTS OF WEIGHT BEARING YOGA TRAINING ON THE BONE RESORPTION MARKERS OF THE POSTMENOPAUSAL WOMEN. THIS STUDY WAS A PRELIMINARY REPORT TO INVESTIGATE THE EFFECTS OF THE WEIGHT BEARING YOGA TRAINING ON BOTH BONE RESORPTION MARKER AND THE QUALITY OF LIFE OF THE POSTMENOPAUSAL WOMEN. THE SAMPLES WERE RECRUITED BY THE PURPOSIVE SAMPLING FROM THE FEMALE CHULALONGKORN UNIVERSITY STAFF AGED BETWEEN 50-60 YEARS. THE SUBJECTS WERE DIVIDED INTO TWO GROUPS: EXPERIMENTAL GROUP AND CONTROL GROUP. THE BASELINE DEMOGRAPHIC DATA, THE BONE RESORPTION MARKER (BETA-CROSSLAPS), THE BONE FORMATION MARKER (P1NP) AND QUALITY OF LIFE (SF-36) DATA WERE COLLECTED. THE EXPERIMENTAL GROUP ATTENDED THE 12-WEEK WEIGHT-BEARING YOGA TRAINING 3 DAYS A WEEK, 50 MINUTES A DAY WHILE THE CONTROL GROUP LIVED THEIR NORMAL LIVES. AFTER 12TH WEEK, THE DATA COLLECTIONS WERE REPEATED IN BOTH GROUPS. THE EXPERIMENTAL GROUP (19 SUBJECTS, THE MEAN AGE 54.320 YRS) AND THE CONTROL GROUP (14 SUBJECTS, THE MEAN AGE 54.430 YRS) WERE RECRUITED. THE MEAN ULTRASOUND BMD OF BOTH HEELS IN BOTH GROUPS SHOWED NO OSTEOPENIA OR OSTEOPOROSIS. AFTER THE 12-WEEK TRAINING, THE MEAN BONE RESORPTION MARKER (BETA-CROSSLAPS) OF THE EXPERIMENTAL GROUP REDUCED FROM 0.464 TO 0.339 NG/ML (-26.939%) WHEREAS THE CONTROL GROUP REDUCED FROM 0.389 TO 0.386 NG/ML (-0.771%). THERE WAS A SIGNIFICANT DIFFERENCE (P < 0.05). THE MEAN OF THE BONE FORMATION MARKERS (PINP) IN THE EXPERIMENTAL GROUP REDUCED FROM 55.393 TO 42.401 NG/ML (-23.454%) AND THE BONE FORMATION MARKERS (PINP) IN THE CONTROL GROUP REDUCED FROM 61.903 TO 44.832 NG/ML (-27.577%). IN THE AREA OF THE LIFE QUALITY MEASUREMENT OF BOTH GROUPS, THE DATA OBTAINED FROM THE MEDICAL OUTCOMES STUDY SHORT-FORM SURVEY (SF-36) SHOWED THAT THERE WERE SIGNIFICANT DIFFERENCES AT 0.05 LEVELS FOR THE PHYSICAL FUNCTIONING, BODILY PAIN, GENERAL HEALTH, AND VITALITY. THE VARIANCE OF PERCENTAGE CHANGE VALUE OF THE EXPERIMENTAL GROUP INCREASED TO +25.299, +16.565, +15.309, AND +21.056. THE VARIANCE OF PERCENTAGE CHANGE VALUE OF THE CONTROL GROUP INCREASED TO +12.946, -1.221, -9.303 AND +2.291. THE WEIGH-BEARING YOGA TRAINING HAD A POSITIVE EFFECT ON BONE BY SLOWING DOWN BONE RESORPTION WHICH WAS A VERY ESSENTIAL INDICATOR FOR HUMAN HEALTH BECAUSE IT REDUCED THE OSTEOPOROSIS RISKS IN THE POSTMENOPAUSAL WOMEN. ADDITIONALLY, YOGA TRAINING PROMOTED BETTER QUALITY OF LIFE.	2009	
                                                                                                                                                                                                                                                                                                                              
6  969  33 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.

7 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	
                                                                                                                        
8  993  14 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

10 1676  31 OBJECTIVE AND SUBJECTIVE MEASURES OF EXERCISE INTENSITY DURING THERMO-NEUTRAL AND HOT YOGA. WHILE HOT YOGA HAS GAINED ENORMOUS POPULARITY IN RECENT YEARS, OWING IN PART TO INCREASED ENVIRONMENTAL CHALLENGE ASSOCIATED WITH EXERCISE IN THE HEAT, IT IS NOT CLEAR WHETHER HOT YOGA IS MORE VIGOROUS THAN THERMO-NEUTRAL YOGA. THEREFORE, THE AIM OF THIS STUDY WAS TO DETERMINE OBJECTIVE AND SUBJECTIVE MEASURES OF EXERCISE INTENSITY DURING CONSTANT INTENSITY YOGA IN A HOT AND THERMO-NEUTRAL ENVIRONMENT. USING A RANDOMIZED, CROSSOVER DESIGN, 14 PARTICIPANTS COMPLETED 2 IDENTICAL APPROXIMATELY 20-MIN YOGA SESSIONS IN A HOT (35.3 +/- 0.8 DEGREES C; HUMIDITY: 20.5% +/- 1.4%) AND THERMO-NEUTRAL (22.1 +/- 0.2 DEGREES C; HUMIDITY: 27.8% +/- 1.6%) ENVIRONMENT. OXYGEN CONSUMPTION AND HEART RATE (HR) WERE RECORDED AS OBJECTIVE MEASURES (PERCENTAGE OF MAXIMAL OXYGEN CONSUMPTION AND PERCENTAGE OF MAXIMAL HR (%HRMAX)) AND RATING OF PERCEIVED EXERTION (RPE) WAS RECORDED AS A SUBJECTIVE MEASURE OF EXERCISE INTENSITY. THERE WAS NO DIFFERENCE IN EXERCISE INTENSITY BASED ON PERCENTAGE OF MAXIMAL OXYGEN CONSUMPTION DURING HOT VERSUS THERMO-NEUTRAL YOGA (30.9% +/- 2.3% VS. 30.5% +/- 1.8%, P = 0.68). HOWEVER, EXERCISE INTENSITY WAS SIGNIFICANTLY HIGHER DURING HOT VERSUS THERMO-NEUTRAL YOGA BASED ON %HRMAX (67.0% +/- 2.3% VS. 60.8% +/- 1.9%, P = 0.01) AND RPE (12 +/- 1 VS. 11 +/- 1, P = 0.04). ACCORDING TO ESTABLISHED EXERCISE INTENSITIES, HOT YOGA WAS CLASSIFIED AS LIGHT-INTENSITY EXERCISE BASED ON PERCENTAGE OF MAXIMAL OXYGEN CONSUMPTION BUT MODERATE-INTENSITY EXERCISE BASED ON %HRMAX AND RPE WHILE THERMO-NEUTRAL YOGA WAS CLASSIFIED AS LIGHT-INTENSITY EXERCISE BASED ON PERCENTAGE OF MAXIMAL OXYGEN UPTAKE, %HRMAX, AND RPE. DESPITE THE ADDED HEMODYNAMIC STRESS AND PERCEPTION THAT YOGA IS MORE STRENUOUS IN A HOT ENVIRONMENT, WE OBSERVED SIMILAR OXYGEN CONSUMPTION DURING HOT VERSUS THERMO-NEUTRAL YOGA, CLASSIFYING BOTH EXERCISE MODALITIES AS LIGHT-INTENSITY EXERCISE.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
11  324  23 ANTHROPOMETRIC, BIOCHEMICAL AND CLINICAL PARAMETERS IN CLIMACTERIC YOGA PRACTITIONERS. OBJECTIVE: THIS STUDY AIMED TO EVALUATE ANTHROPOMETRIC, BIOCHEMICAL AND CLINICAL PARAMETERS IN CLIMACTERIC YOGA PRACTITIONERS. METHODS: THIS STUDY INVESTIGATED 108 CLIMACTERIC WOMEN. WE RECRUITED 28 WOMEN BETWEEN 40 AND 65 YEARS OLD WHO STARTED YOGA PRACTICES IN PREMENOPAUSE AND HAD ALREADY PRACTICED FOR AT LEAST 5 YEARS. AS CONTROLS, WE SELECTED 30 PHYSICAL ACTIVITY (PA) PRACTITIONERS WHO HAD PRACTICED FOR AT LEAST 5 YEARS AND 50 SEDENTARY WOMEN IN THE SAME AGE RANGE. WE CONDUCED ANTHROPOMETRIC, BIOCHEMICAL AND BLOOD PRESSURE MEASUREMENTS. RESULTS: THE YOGA GROUP HAD SIGNIFICANTLY LOWER FASTING BLOOD GLUCOSE THAN THE PA PRACTITIONERS AND SEDENTARY WOMEN. YOGA PRACTITIONERS ALSO HAD LOWER WEIGHT, BODY MASS INDEX, WAIST CIRCUMFERENCE, BODY FAT PERCENTAGE AND WAIST-TO-HEIGHT RATIO; HIGHER LEVELS OF HIGH-DENSITY LIPOPROTEIN CHOLESTEROL; LOWER LEVELS OF TRIGLYCERIDES, INSULIN, HOMEOSTASIS MODEL ASSESSMENT OF INSULIN RESISTANCE, URIC ACID, APOLIPOPROTEIN B AND HIGH-SENSITIVITY C-REACTIVE PROTEIN; AND LOWER FREQUENCY OF METABOLIC SYNDROME, LIPID ACCUMULATION PRODUCT, VISCERAL ADIPOSITY INDEX AND SYSTOLIC BLOOD PRESSURE THAN THE SEDENTARY WOMEN. CONCLUSION: YOGA PRACTITIONERS HAD LOWER GLUCOSE SERUM CONCENTRATIONS THAN THE PA PRACTITIONERS AND SEDENTARY WOMEN. OVERALL, THE YOGA GROUP ALSO HAD BETTER ANTHROPOMETRIC, BIOCHEMICAL AND CLINICAL VARIABLES THAN THE OTHER GROUPS. ALTHOUGH FURTHER INVESTIGATION IS REQUIRED, YOGA PRACTICE IN PREMENOPAUSE SEEMS TO BE BENEFICIAL FOR WOMEN WHEN THEY REACH MENOPAUSE.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
12 1298  29 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
13 1030  27 EFFECTS OF YOGA EXERCISE ON SERUM ADIPONECTIN AND METABOLIC SYNDROME FACTORS IN OBESE POSTMENOPAUSAL WOMEN. OBJECTIVE: REGULAR AND CONTINUOUS YOGA EXERCISE IS ONE OF THE MOST IMPORTANT NONPHARMACOLOGICAL METHODS OF IMPROVING SERUM LIPID CONCENTRATIONS, ADIPOSE TISSUE, AND METABOLIC SYNDROME FACTORS. THE PURPOSE OF THIS STUDY WAS TO ANALYZE THE EFFECTS OF YOGA EXERCISE ON SERUM ADIPONECTIN AND METABOLIC SYNDROME FACTORS IN OBESE POSTMENOPAUSAL KOREAN WOMEN. METHODS: SIXTEEN HEALTHY POSTMENOPAUSAL WOMEN AGED 54.50 +/- 2.75 YEARS WITH MORE THAN 36% BODY FAT WERE RANDOMLY ASSIGNED TO EITHER A YOGA EXERCISE GROUP (N = 8) OR TO A "NO EXERCISE" CONTROL GROUP (N = 8). THE VARIABLES OF BODY COMPOSITION, VISCERAL FAT, SERUM ADIPONECTIN, AND METABOLIC SYNDROME FACTORS WERE MEASURED IN ALL THE PARTICIPANTS BEFORE AND AFTER THE 16-WEEK STUDY. RESULTS: BODY WEIGHT, PERCENTAGE OF BODY FAT, LEAN BODY MASS, BODY MASS INDEX, WAIST CIRCUMFERENCE, AND VISCERAL FAT AREA HAD SIGNIFICANTLY DECREASED. HIGH-DENSITY LIPOPROTEIN CHOLESTEROL AND ADIPONECTIN HAD SIGNIFICANTLY INCREASED, BUT TOTAL CHOLESTEROL, TRIGLYCERIDE, LOW-DENSITY LIPOPROTEIN CHOLESTEROL, BLOOD PRESSURE, INSULIN, GLUCOSE, AND HOMOEOSTASIS MODEL ASSESSMENT-INSULIN RESISTANCE HAD SIGNIFICANTLY DECREASED. SERUM ADIPONECTIN CONCENTRATIONS WERE SIGNIFICANTLY CORRELATED WITH WAIST CIRCUMFERENCE, HIGH-DENSITY LIPOPROTEIN CHOLESTEROL, DIASTOLIC BLOOD PRESSURE, AND HOMOEOSTASIS MODEL ASSESSMENT-INSULIN RESISTANCE IN THE POSTYOGA EXERCISE GROUP. CONCLUSIONS: OUR FINDINGS INDICATE THAT YOGA EXERCISE IMPROVES ADIPONECTIN LEVEL, SERUM LIPIDS, AND METABOLIC SYNDROME RISK FACTORS IN OBESE POSTMENOPAUSAL WOMEN. CONSEQUENTLY, YOGA EXERCISE WILL BE EFFECTIVE IN PREVENTING CARDIOVASCULAR DISEASE CAUSED BY OBESITY IN OBESE POSTMENOPAUSAL KOREAN WOMEN.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
14 2075  35 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
15 2193  27 THE EFFECTS OF YOGA TRAINING AND A SINGLE BOUT OF YOGA ON DELAYED ONSET MUSCLE SORENESS IN THE LOWER EXTREMITY. THE PURPOSE OF THIS STUDY WAS TO DETERMINE THE EFFECTS OF YOGA TRAINING AND A SINGLE BOUT OF YOGA ON THE INTENSITY OF DELAYED ONSET MUSCLE SORENESS (DOMS). 24 YOGA-TRAINED (YT; N = 12) AND NON-YOGA-TRAINED (CON; N = 12), MATCHED WOMEN VOLUNTEERS WERE ADMINISTERED A DOMS-INDUCING BENCH-STEPPING EXERCISE. MUSCLE SORENESS WAS ASSESSED AT BASELINE, 24, 48, 72, 96, AND 120 HOURS AFTER BENCH-STEPPING USING A VISUAL ANALOG SCALE (VAS). GROUPS WERE ALSO COMPARED ON BODY AWARENESS (BA), FLEXIBILITY USING THE SIT-AND-REACH TEST (SR), AND PERCEIVED EXERTION (RPE). STATISTICAL SIGNIFICANCE WAS ACCEPTED AT P </= 0.05. A 2 X 2 MIXED FACTORIAL ANOVA WITH REPEATED MEASURES AT 24 AND 48 HOURS REVEALED A SIGNIFICANT (P < 0.05) GROUP MAIN EFFECT WITH VAS SCORES GREATER FOR CON THAN YT. PAIRED T-TESTS REVEALED THAT IN YT, VAS SCORES WERE HIGHER BEFORE YOGA CLASS THAN AFTER YOGA CLASS AT 24 HOURS (21.4 [+/- 6.9] MM VS. 11.1 [+/- 4.1] MM; P = 0.02). THE SR WAS GREATER IN YT THAN IN CON (65.0 [+/- 7.9] CM VS. 33.3 [+/- 7.0] CM; P < 0.01); HOWEVER, NO DIFFERENCES WERE FOUND BETWEEN YOGA AND CONTROL IN BA (94.0 [+/- 4.4] UNITS VS. 83.8 [+/- 3.7] UNITS; P = 0.21) OR IN RPE AT 5-MINUTE INTERVALS (2.9 [+/- 0.3], 5.3 [+/- 0.8], 5.8 [+/- 0.9], AND 5.2 [+/- 0.8] VS. 2.5 [+/- 0.3], 4.0 [+/- 0.5], 4.2 [+/- 0.3], AND 4.9 [+/- 0.4]. YOGA TRAINING AND A SINGLE BOUT OF YOGA APPEAR TO ATTENUATE PEAK MUSCLE SORENESS IN WOMEN FOLLOWING A BOUT OF ECCENTRIC EXERCISE. THESE FINDINGS HAVE SIGNIFICANT IMPLICATIONS FOR COACHES, ATHLETES, AND THE EXERCISING PUBLIC WHO MAY WANT TO IMPLEMENT YOGA TRAINING AS A PRESEASON REGIMEN OR SUPPLEMENTAL ACTIVITY TO LESSEN THE SYMPTOMS ASSOCIATED WITH MUSCLE SORENESS.	2004	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
16 2816  28 YOGA TRAINING IMPROVES METABOLIC PARAMETERS IN OBESE BOYS. YOGA HAS BEEN KNOWN TO HAVE STIMULATORY OR INHIBITORY EFFECTS ON THE METABOLIC PARAMETERS AND TO BE UNCOMPLICATED THERAPY FOR OBESITY. THE PURPOSE OF THE PRESENT STUDY WAS TO TEST THE EFFECT OF AN 8-WEEK OF YOGA-ASANA TRAINING ON BODY COMPOSITION, LIPID PROFILE, AND INSULIN RESISTANCE (IR) IN OBESE ADOLESCENT BOYS. TWENTY VOLUNTEERS WITH BODY MASS INDEX (BMI) GREATER THAN THE 95TH PERCENTILE WERE RANDOMLY ASSIGNED TO YOGA (AGE 14.7+/-0.5 YEARS, N=10) AND CONTROL GROUPS (AGE 14.6+/-1.0 YEARS, N=10). THE YOGA GROUP PERFORMED EXERCISES THREE TIMES PER WEEK AT 40~60% OF HEART-RATE RESERVE (HRR) FOR 8 WEEKS. IR WAS DETERMINED WITH THE HOMEOSTASIS MODEL ASSESSMENT OF INSULIN RESISTANCE (HOMA-IR). AFTER YOGA TRAINING, BODY WEIGHT, BMI, FAT MASS (FM), AND BODY FAT % (BF %) WERE SIGNIFICANTLY DECREASED, AND FAT-FREE MASS AND BASAL METABOLIC RATE WERE SIGNIFICANTLY INCREASED THAN BASELINE VALUES. FM AND BF % WERE SIGNIFICANTLY IMPROVED IN THE YOGA GROUP COMPARED WITH THE CONTROL GROUP (P<0.05). TOTAL CHOLESTEROL (TC) WAS SIGNIFICANTLY DECREASED IN THE YOGA GROUP (P<0.01). HDL-CHOLESTEROL WAS DECREASED IN BOTH GROUPS (P<0.05). NO SIGNIFICANT CHANGES WERE OBSERVED BETWEEN OR WITHIN GROUPS FOR TRIGLYCERIDES, LDL-CHOLESTEROL, GLUCOSE, INSULIN, AND HOMA-IR. OUR FINDINGS SHOW THAT AN 8-WEEK OF YOGA TRAINING IMPROVES BODY COMPOSITION AND TC LEVELS IN OBESE ADOLESCENT BOYS, SUGGESTING THAT YOGA TRAINING MAY BE EFFECTIVE IN CONTROLLING SOME METABOLIC SYNDROME FACTORS IN OBESE ADOLESCENT BOYS.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
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	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
18 2076  28 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
19 1968  33 SERUM MINERAL STATUS AND CLIMACTERIC SYMPTOMS IN PERIMENOPAUSAL WOMEN BEFORE AND AFTER YOGA THERAPY, AN ONGOING STUDY. BACKGROUND: MANY WOMEN REPORT AN INCREASED LEVEL OF ANXIETY, IRRITABILITY AND MOOD SWINGS DURING THEIR PERIMENOPAUSAL STATE. STUDIES SHOW THAT PHYSICALLY ACTIVE PEOPLE CAN REDUCE THEIR ANXIETY AND DEPRESSION BY PRACTICING YOGA. SERUM MINERALS SUCH AS CALCIUM, COPPER AND MAGNESIUM AND THE FERRO-OXIDASE, CERULOPLASMIN PLAY AN IMPORTANT ROLE IN THE BODY DURING THE PERIMENOPAUSAL PERIOD. OBJECTIVE: THE OBJECTIVE OF THIS STUDY IS TO ASSESS THE SERUM MINERAL STATUS, ANTHROPOMETRIC PARAMETERS AND CLIMACTERIC SYMPTOMS IN PERIMENOPAUSAL WOMEN BEFORE AND AFTER YOGA INTERVENTION. SUBJECTS AND METHODS: A TOTAL OF 30 SUBJECTS WITH PERIMENOPAUSAL SYMPTOMS, AGED BETWEEN 40 AND 60 YEARS (49.43 +/- 6.15) WERE INCLUDED IN THE STUDY. YOGA INTERVENTION WAS GIVEN ON A DAILY BASIS (45 MIN DURATION) FOR 12 WEEKS. THE CLIMACTERIC SYMPTOMS WERE ASSESSED BY GREENE'S CLIMACTERIC SCALE AND BIOCHEMICAL PARAMETERS WERE ANALYZED SPECTROPHOTOMETRICALLY. RESULTS: A SIGNIFICANT DECREASE IN THE WAIST HIP RATIO (P < 0.036) AND BODY MASS INDEX (P < 0.036) WAS OBSERVED AFTER YOGA INTERVENTION. SYSTOLIC (P < 0.064) AND DIASTOLIC (P < 0.082) BLOOD PRESSURE (BP) SHOWED MARGINAL DECREASE AFTER YOGA THERAPY. CLIMACTERIC SYMPTOMS IMPROVED SIGNIFICANTLY (P < 0.001) AFTER YOGA INTERVENTION. A SIGNIFICANT INCREASE (P < 0.001) IN SERUM CALCIUM AND COPPER AND A MARKED DECREASE IN SERUM MAGNESIUM (P < 0.05) AND CERULOPLASMIN (P < 0.028) LEVELS WAS OBSERVED, POST YOGA THERAPY. SERUM MAGNESIUM NEGATIVELY CORRELATED (R = -0.467, P < 0.035) WITH SYSTOLIC BP AFTER YOGA INTERVENTION. CONCLUSION: THE OVERALL CHANGES OBSERVED IN THE MINERAL STATUS AND CLIMACTERIC SYMPTOMS SUGGEST THAT YOGA THERAPY PROTOCOL CAN BE EFFECTIVELY USED TO IMPROVE THE QUALITY OF LIFE IN PERIMENOPAUSAL WOMEN.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
20   90  22 A MODIFIED YOGA-BASED EXERCISE PROGRAM IN HEMODIALYSIS PATIENTS: A RANDOMIZED CONTROLLED STUDY. AIM: TO EVALUATE THE EFFECTS OF A YOGA-BASED EXERCISE PROGRAM ON PAIN, FATIGUE, SLEEP DISTURBANCE, AND BIOCHEMICAL MARKERS IN HEMODIALYSIS PATIENTS. MATERIALS AND METHODS: IN 2004 A RANDOMIZED CONTROLLED TRIAL WAS CARRIED OUT IN THE OUTPATIENT HEMODIALYSIS UNIT OF THE NEPHROLOGY DEPARTMENT, ULUDAG UNIVERSITY FACULTY OF MEDICINE. CLINICALLY STABLE HEMODIALYSIS PATIENTS (N=37) WERE INCLUDED AND FOLLOWED IN TWO GROUPS: THE MODIFIED YOGA-BASED EXERCISE GROUP (N=19) AND THE CONTROL GROUP (N=18). YOGA-BASED EXERCISES WERE DONE IN GROUPS FOR 30 MIN/DAY TWICE A WEEK FOR 3 MONTHS. ALL OF THE PATIENTS IN THE YOGA AND CONTROL GROUPS WERE GIVEN AN ACTIVE RANGE OF MOTION EXERCISES TO DO FOR 10 MIN AT HOME. THE MAIN OUTCOME MEASURES WERE PAIN INTENSITY (MEASURED BY THE VISUAL ANALOGUE SCALE, VAS), FATIGUE (VAS), SLEEP DISTURBANCE (VAS), AND GRIP STRENGTH (MMHG); BIOCHEMICAL VARIABLES-- UREA, CREATININE, CALCIUM, ALKALINE PHOSPHATASE, PHOSPHORUS, CHOLESTEROL, HDL-CHOLESTEROL, TRIGLYCERIDE, ERYTHROCYTE, HEMATOCRIT--WERE EVALUATED. RESULTS: AFTER A 12-WEEK INTERVENTION, SIGNIFICANT IMPROVEMENTS WERE SEEN IN THE VARIABLES: PAIN -37%, FATIGUE -55%, SLEEP DISTURBANCE -25%, GRIP STRENGTH +15%, UREA -29%, CREATININE -14%, ALKALINE PHOSPHATASE -15%, CHOLESTEROL -15%, ERYTHROCYTE +11%, AND HEMATOCRIT COUNT +13%; NO SIDE-EFFECTS WERE SEEN. IMPROVEMENT OF THE VARIABLES IN THE YOGA-BASED EXERCISE PROGRAM WAS FOUND TO BE SUPERIOR TO THAT IN THE CONTROL GROUP FOR ALL THE VARIABLES EXCEPT CALCIUM, PHOSPHORUS, HDL-CHOLESTEROL AND TRIGLYCERIDE LEVELS. CONCLUSION: A SIMPLIFIED YOGA-BASED REHABILITATION PROGRAM IS A COMPLEMENTARY, SAFE AND EFFECTIVE CLINICAL TREATMENT MODALITY IN PATIENTS WITH END-STAGE RENAL DISEASE.	2007
