1  624 122 DIABETES MELLITUS TYPE 2 AND YOGA: ELECTRO PHOTONIC IMAGING PERSPECTIVE. BACKGROUND: YOGA IS THE MOST POPULAR FORM OF ALTERNATIVE MEDICINE FOR THE MANAGEMENT OF DIABETES MELLITUS TYPE 2. THE ELECTRO-PHOTONIC IMAGING (EPI) IS ANOTHER CONTRIBUTION FROM ALTERNATIVE MEDICINE IN HEALTH MONITORING. AIM: TO EVALUATE DIABETES FROM EPI PERSPECTIVE. OBJECTIVES: (1) COMPARE VARIOUS EPI PARAMETERS IN NORMAL, PREDIABETIC AND DIABETIC PATIENTS. (2) FIND DIFFERENCE IN CONTROLLED AND UNCONTROLLED DIABETES. (3) STUDY THE EFFECT OF 7 DAYS DIABETES-SPECIFIC YOGA PROGRAM. MATERIALS AND METHODS: FOR THE FIRST OBJECTIVE, THERE WERE 102 PATIENTS (NORMAL 29, PREDIABETIC 13, DIABETIC 60). IN THE SECOND STUDY, THERE WERE 60 PATIENTS (CONTROLLED DIABETES 27, UNCONTROLLED DIABETES 33). THE THIRD STUDY COMPRISED 37 PATIENTS. EPI PARAMETERS WERE RELATED TO GENERAL HEALTH AS WELL TO SPECIFIC ORGANS. RESULTS: IN THE FIRST STUDY, SIGNIFICANT DIFFERENCE WAS OBSERVED BETWEEN (1) DIABETICS AND NORMAL: AVERAGE INTENSITY 5.978, FORM COEFFICIENT 3.590, IMMUNE ORGANS 0.281 ALL P < 0.001; (2) DIABETICS AND PREDIABETICS: AVERAGE INTENSITY 6.676, FORM COEFFICIENT 4.158, IMMUNE ORGANS 5.890 P < 0.032; (3) NORMAL AND PREDIABETES: IMMUNE ORGANS (-6.171 P = 000). IN THE SECOND STUDY, REMARKABLE DIFFERENCE WAS IN THE IMMUNE ORGANS (0.201, P = 0.031). IN THE PRE- AND POST-STUDY, THE MEAN DIFFERENCE WAS: AREA 630.37, FORM COEFFICIENT 1.78, ENTROPY 0.03, LIVER 0.24, PANCREAS 0.17, CORONARY VESSELS 0.11, AND LEFT KIDNEY 29, WITH ALL P < 0.02. CONCLUSION: THERE IS A SIGNIFICANT DIFFERENCE IN EPI PARAMETERS BETWEEN NORMAL, PREDIABETICS AND DIABETICS, THE PROMINENT BEING AVERAGE INTENSITY, FORM COEFFICIENT, AND IMMUNE ORGANS. BETWEEN CONTROLLED AND UNCONTROLLED DIABETES, IMMUNE ORGANS SHOW SIGNIFICANT CHANGE. INTERVENTION OF YOGA RESULTS IN CHANGE IN MOST PARAMETERS.	2017	
                                                                                                                                                                                                                                                                                                                  
2 1498  27 INTRAOCULAR PRESSURE CHANGES AND OCULAR BIOMETRY DURING SIRSASANA (HEADSTAND POSTURE) IN YOGA PRACTITIONERS. PURPOSE: TO STUDY THE INTRAOCULAR PRESSURE (IOP) CHANGES IN SIRSASANA (HEADSTAND POSTURE) DONE BY EXPERIENCED YOGA PRACTITIONERS AND CORRELATE THE OCULAR BIOMETRIC PARAMETERS WITH THE IOP CHANGES, AND TO SCREEN FOR THE PREVALENCE OF OCULAR HYPERTENSION IN THIS GROUP OF SUBJECTS. DESIGN: PROSPECTIVE CASE OBSERVATIONAL SERIES. PARTICIPANTS: SEVENTY-FIVE SUBJECTS (50 ASIAN INDIANS AND 25 CAUCASIANS) FROM A YOGA TRAINING INSTITUTE VOLUNTEERED FOR THE STUDY. METHODS: ALL PARTICIPANTS UNDERWENT A DETAILED OPHTHALMIC EXAMINATION ALONG WITH OCULAR BIOMETRY AND CORNEAL PACHYMETRY. INTRAOCULAR PRESSURE WAS RECORDED USING A TONOPEN BEFORE, DURING, AND AFTER THE SIRSASANA. CHANGES WERE COMPARED USING THE PAIRED T TEST. AGE, AXIAL LENGTH, ANTERIOR CHAMBER DEPTH, LENS THICKNESS, CORNEAL CURVATURE, CORNEAL THICKNESS, RACE, AND THE LENGTH OF TIME FOR WHICH THE PRACTITIONER WAS PERFORMING YOGA WERE CORRELATED WITH THE INDUCED IOP DIFFERENCE IN A RANDOMLY SELECTED EYE USING PEARSON'S CORRELATION COEFFICIENT WITH BONFERRONI CORRECTION FOR MULTIPLE COMPARISONS. MAIN OUTCOME MEASURES: OCULAR BIOMETRY AND INDUCED IOP DIFFERENCE. RESULTS: THE MEAN INCREASE IN IOP AT BASELINE AND IMMEDIATELY AFTER ASSUMING SIRSASANA WAS 15.1+/-4.1 MMHG (R = 0.07; P = 0.999) AND AFTER 5 MINUTES WAS 15.8+/-4.6 MMHG (R = -0.25; P = 0.357). THE INDUCED INCREASE IN IOP DURING THE POSTURE WAS TWICE THE BASELINE IOP. THERE WAS NO CORRELATION BETWEEN AGE, OCULAR BIOMETRY, AND ULTRASOUND PACHYMETRY WHEN COMPARED WITH THE INDUCED IOP DIFFERENCE. ONE SUBJECT (1.33%) WAS FOUND TO HAVE BASELINE IOP OF MORE THAN 21 MMHG. CONCLUSION: THERE WAS A UNIFORM 2-FOLD INCREASE IN THE IOP DURING SIRSASANA, WHICH WAS MAINTAINED DURING THE POSTURE IN ALL AGE GROUPS IRRESPECTIVE OF THE OCULAR BIOMETRY AND ULTRASOUND PACHYMETRY. WE DID NOT DEMONSTRATE A HIGHER PREVALENCE OF OCULAR HYPERTENSIVES IN THIS COHORT OF YOGA PRACTITIONERS NOR DID THE RISK FACTORS CONTRIBUTING TO GLAUCOMA SHOW ANY CORRELATION WITH MAGNITUDE OF IOP RAISE DURING THE POSTURE.	2006	
                           
3  785  38 EFFECT OF YOGA BASED TECHNIQUES ON STRESS AND HEALTH INDICES USING ELECTRO PHOTONIC IMAGING TECHNIQUE IN MANAGERS. BACKGROUND: MEDITATION TECHNIQUES ARE KNOWN TO ELICIT RELAXATION RESPONSE IN WHICH MOVING MEDITATION WHICH COMBINES THE PRACTICE OF YOGA POSTURES AND GUIDED RELAXATION IS KNOWN AS CYCLIC MEDITATION REPORTED HELPFUL IN REDUCING THE SYMPATHETIC AROUSAL AND IMPROVING HEALTH OF PRACTITIONERS. OBJECTIVES: THE OBJECTIVE OF THIS STUDY WAS TO INVESTIGATE THE EFFECT OF CYCLIC MEDITATION ON STRESS AND HEALTH INDICES IN MANAGERS AS MEASURED BY ELECTRO PHOTONIC IMAGING (EPI) TECHNIQUE. MATERIALS AND METHODS: EPI TECHNIQUE WAS USED TO ASSESS PARTICIPANTS BEFORE AND AFTER 35 MIN OF CYCLIC MEDITATION (CM) AND EQUAL DURATION OF SUPINE REST (SR) SESSION. A TOTAL OF SIXTY SIX MALE MANAGERS, AGE RANGES FROM 35 TO 60 YEARS (MEAN +/- SD 53.97 +/- 5.96) WERE INCLUDED IN THE STUDY. EPI PARAMETERS, INCLUDING ACTIVATION COEFFICIENT, INTEGRAL AREA LEFT AND RIGHT AND INTEGRAL ENTROPY, LEFT AND RIGHT WERE TAKEN FOR STATISTICAL ANALYSES. RESULTS: CYCLIC MEDITATION HAS PRODUCED A HIGHLY SIGNIFICANT REDUCTION IN STRESS LEVEL, WHEREAS THIS REDUCTION WAS NOT FOUND SIGNIFICANT WITHIN SR GROUP. THERE WAS A SIGNIFICANT IMPROVEMENT IN HEALTH INDEX 'INTEGRAL AREA' VALUES IN BOTH LEFT AND RIGHT SIDES WITHIN THE CM GROUP WHILE ONLY IA RIGHT SIDE SHOWED A SIGNIFICANT IMPROVEMENT WITHIN THE CM GROUP. THE INTEGRAL ENTROPY VALUE RIGHT SIDE DECREASED SIGNIFICANTLY WITHIN THE CM GROUP, WHEREAS IE LEFT WAS FOUND DETERIORATED WITHIN THE SR GROUP. MOREOVER, ONLY IE LEFT SIDE HAS SHOWN A SIGNIFICANT DIFFERENCE BETWEEN THE GROUPS. CONCLUSION: THE INVESTIGATIONS IN THIS STUDY SUGGEST THAT CYCLIC MEDITATION PRACTICE REDUCES STRESS AND IMPROVES PSYCHOSOMATIC HEALTH INDICES MORE EFFECTIVELY THAN SUPINE REST IN MANAGERS.	2016	
                                                                                                                                                                                                                                                                                                                                                     
4 1803  31 PREVALENCE OF DIABETES AND ITS DETERMINANTS IN THE YOUNG ADULTS INDIAN POPULATION-CALL FOR YOGA INTERVENTION. BACKGROUND: THE YOUNG INDIAN POPULATION, WHICH CONSTITUTES 65% OF THE COUNTRY, IS FAST ADAPTING TO A NEW LIFESTYLE, WHICH WAS NOT KNOWN EARLIER. THEY ARE AT A HIGH RISK OF THE INCREASING BURDEN OF DIABETES AND ASSOCIATED COMPLICATIONS. THE NEW EVOLVING LIFESTYLE IS NOT ONLY AFFECTING PEOPLE'S HEALTH BUT ALSO MOUNTING THE MONETARY BURDEN ON A DEVELOPING COUNTRY SUCH AS INDIA. AIM: WE AIMED TO COLLECT INFORMATION REGARDING THE PREVALENCE OF RISK OF DIABETES IN YOUNG ADULTS (<35 YEARS) IN THE 29 MOST POPULOUS STATES AND UNION TERRITORIES (7 ZONES) OF INDIA, USING A VALIDATED QUESTIONNAIRE. METHODS: A USER-FRIENDLY QUESTIONNAIRE-BASED SURVEY USING A MOBILE APPLICATION WAS CONDUCTED ON ALL ADULTS IN THE 29 MOST POPULOUS STATES/UNION TERRITORIES OF INDIA, AFTER OBTAINING ETHICAL CLEARANCE FOR THE STUDY. HERE, WE REPORT THE ESTIMATION OF THE PREVALENCE OF THE RISK OF DIABETES AND SELF-REPORTED DIABETES ON 58,821 YOUNG INDIVIDUALS BELOW THE AGE OF 35 YEARS. RISK FOR DIABETES WAS ASSESSED USING A STANDARDIZED INSTRUMENT, THE INDIAN DIABETES RISK SCORE (IDRS), THAT HAS 4 FACTORS (AGE, FAMILY HISTORY OF DIABETES, WAIST CIRCUMFERENCE, AND PHYSICAL ACTIVITY). SPEARMAN'S CORRELATION COEFFICIENT WAS USED TO CHECK THE CORRELATIONS. RESULTS: THE PREVALENCE OF HIGH (IDRS SCORE > 60), MODERATE (IDRS SCORE 30-50), AND LOW (IDRS < 30) DIABETES RISK IN YOUNG ADULTS (<35 YEARS) WAS 10.2%, 33.1%, AND 56.7%, RESPECTIVELY. THOSE WITH HIGH-RISK SCORES WERE HIGHEST (14.4%) IN THE JAMMU ZONE AND LOWEST (4.1%) IN THE CENTRAL ZONE. THE PREVALENCE OF SELF-REPORTED DIABETES WAS 1.8% WITH A SMALL DIFFERENCE BETWEEN MEN (1.7%) AND WOMEN (1.9%), AND THE HIGHEST (8.4%) IN THOSE WITH A PARENTAL HISTORY OF DIABETES. THE SOUTH ZONE HAD THE HIGHEST (2.5%), AND THE NORTH WEST ZONE HAD THE LOWEST (4.4%) PREVALENCE. CONCLUSIONS: INDIAN YOUTH ARE AT HIGH RISK FOR DIABETES, WHICH CALLS FOR AN URGENT ACTION PLAN THROUGH INTENSIVE EFFORTS TO PROMOTE LIFESTYLE BEHAVIOR MODIFICATIONS DURING THE PANDEMICS OF BOTH COMMUNICABLE AND NONCOMMUNICABLE DISEASES.	2020	

5  814  24 EFFECT OF YOGA ON CARDIOVASCULAR SYSTEM IN SUBJECTS ABOVE 40 YEARS. THIS STUDY WAS CONDUCTED TO EXAMINE THE EFFECT OF YOGA ON CARDIOVASCULAR FUNCTION IN SUBJECTS ABOVE 40 YRS OF AGE. PULSE RATE, SYSTOLIC AND DIASTOLIC BLOOD PRESSURE AND VALSALVA RATIO WERE STUDIED IN 50 CONTROL SUBJECTS (NOT DOING ANY TYPE OF PHYSICAL EXERCISE) AND 50 STUDY SUBJECTS WHO HAD BEEN PRACTICING YOGA FOR 5 YEARS. FROM THE STUDY IT WAS OBSERVED THAT SIGNIFICANT REDUCTION IN THE PULSE RATE OCCURS IN SUBJECTS PRACTICING YOGA (P<0.001). THE DIFFERENCE IN THE MEAN VALUES OF SYSTOLIC AND DIASTOLIC BLOOD PRESSURE BETWEEN STUDY GROUP AND CONTROL GROUP WAS ALSO STATISTICALLY SIGNIFICANT (P<0.01 AND P<0.001 RESPECTIVELY). THE SYSTOLIC AND DIASTOLIC BLOOD PRESSURE SHOWED SIGNIFICANT POSITIVE CORRELATION WITH AGE IN THE STUDY GROUP (R1 SYSTOLIC= 0.631 AND R1 DIASTOLIC = 0.610) AS WELL AS IN THE CONTROL GROUP (R2 SYSTOLIC = 0.981 AND R2 DIASTOLIC = 0.864). THE SIGNIFICANCE OF DIFFERENCE BETWEEN CORRELATION COEFFICIENT OF BOTH THE GROUPS WAS ALSO TESTED WITH THE USE OF Z TRANSFORMATION AND THE DIFFERENCE WAS SIGNIFICANT (Z SYSTOLIC= 4.041 AND Z DIASTOLIC= 2.901). VALSALVA RATIO WAS ALSO FOUND TO BE SIGNIFICANTLY HIGHER IN YOGA PRACTITIONERS THAN IN CONTROLS (P<0.001). OUR RESULTS INDICATE THAT YOGA REDUCES THE AGE RELATED DETERIORATION IN CARDIOVASCULAR FUNCTIONS.	2003	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
6 2242  27 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
7  300  20 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
8 2499  24 YOGA AS STEADINESS TRAINING: EFFECTS ON MOTOR VARIABILITY IN YOUNG ADULTS. EXERCISE TRAINING PROGRAMS CAN INCREASE STRENGTH AND IMPROVE SUBMAXIMAL FORCE CONTROL, BUT THE EFFECTS OF YOGA AS AN ALTERNATIVE FORM OF STEADINESS TRAINING ARE NOT WELL DESCRIBED. THE PURPOSE WAS TO EXPLORE THE EFFECT OF A POPULAR TYPE OF YOGA (BIKRAM) ON STRENGTH, STEADINESS, AND BALANCE. YOUNG ADULTS PERFORMED YOGA TRAINING (N = 10, 29 +/- 6 YEARS, 24 YOGA SESSIONS IN 8 WEEKS) OR SERVED AS CONTROLS (N = 11, 26 +/- 7 YEARS). YOGA SESSIONS CONSISTED OF 1.5 HOURS OF SUPERVISED, STANDARDIZED POSTURES. MEASURES BEFORE AND AFTER TRAINING INCLUDED MAXIMUM VOLUNTARY CONTRACTION (MVC) FORCE OF THE ELBOW FLEXORS (EF) AND KNEE EXTENSORS (KE), STEADINESS OF ISOMETRIC EF AND KE CONTRACTIONS, STEADINESS OF CONCENTRIC (CON) AND ECCENTRIC (ECC) KE CONTRACTIONS, AND TIMED BALANCE. THE STANDARD DEVIATION (SD) AND COEFFICIENT OF VARIATION (CV, SD/MEAN FORCE) OF ISOMETRIC FORCE AND THE SD OF ACCELERATION DURING CON AND ECC CONTRACTIONS WERE MEASURED. AFTER YOGA TRAINING, MVC FORCE INCREASED 14% FOR KE (479 +/- 175 TO 544 +/- 187 N, P < 0.05) AND WAS UNCHANGED FOR THE EF MUSCLES (219 +/- 85 TO 230 +/- 72 N, P > 0.05). THE CV OF FORCE WAS UNCHANGED FOR EF (1.68 TO 1.73%, P > 0.05) BUT WAS REDUCED IN THE KE MUSCLES SIMILARLY FOR YOGA AND CONTROL GROUPS (2.04 TO 1.55%, P < 0.05). THE VARIABILITY OF CON AND ECC CONTRACTIONS WAS UNCHANGED. FOR THE YOGA GROUP, IMPROVEMENT IN KE STEADINESS WAS CORRELATED WITH PRETRAINING STEADINESS (R = -0.62 TO -0.84, P < 0.05); SUBJECTS WITH THE GREATEST KE FORCE FLUCTUATIONS BEFORE TRAINING EXPERIENCED THE GREATEST REDUCTIONS WITH TRAINING. PERCENT CHANGE IN BALANCE TIME FOR INDIVIDUAL YOGA SUBJECTS AVERAGED +228% (19.5 +/- 14 TO 34.3 +/- 18 SECONDS, P < 0.05), WITH NO CHANGE IN CONTROLS. FOR YOUNG ADULTS, A SHORT-TERM YOGA PROGRAM OF THIS TYPE CAN IMPROVE BALANCE SUBSTANTIALLY, PRODUCE MODEST IMPROVEMENTS IN LEG STRENGTH, AND IMPROVE LEG MUSCLE CONTROL FOR LESS-STEADY SUBJECTS.	2008	
                                                                                                                                                        
9 1494  32 INTERRATER RELIABILITY OF AN OBSERVATIONAL RATING SCALE AND VIDEO ANALYSIS OF YOGA POSES. CONTEXT: YOGA IS INCREASINGLY POPULAR, NOT ONLY AS A FORM OF RECREATIONAL EXERCISE BUT ALSO AS A PHYSICIAN-RECOMMENDED INTERVENTION FOR HEALTH CONDITIONS. WHILE SERIOUS ADVERSE EFFECTS ACCOMPANYING YOGA PRACTICE ARE RARE, POSES THAT INVOLVE UPPER-EXTREMITY WEIGHT-BEARING HAVE A HIGH RISK OF DISCOMFORT. TO BETTER UNDERSTAND FACTORS CONTRIBUTING TO ADVERSE EFFECTS, THERE IS A CRITICAL NEED FOR ROBUST INSTRUMENTS THAT OBJECTIVELY EVALUATE POSE PERFORMANCE. THE PURPOSE OF THIS STUDY WAS TO ASSESS THE INTERRATER RELIABILITY OF AN OBSERVATIONAL SCALE DEVELOPED TO ASSESS THE ALIGNMENT OF 3 YOGA POSES. DESIGN: CROSS-SECTIONAL EXPERIMENTAL STUDY. METHODS: THIRTY-EIGHT INDIVIDUALS WERE GIVEN STANDARDIZED INSTRUCTIONS AND PERFORMED 3 POSES (DOWNWARD DOG, PLANK, AND SIDE PLANK). LATERAL VIDEOS WERE RATED BY 2 RATERS. A RATING SCALE EVALUATING THE ALIGNMENT OF 7 REGIONS WAS DEVELOPED BY THE STUDY TEAM WITH INPUT FROM YOGA TEACHERS. DESCRIPTIVE STATISTICS WERE USED TO SUMMARIZE THE PERCENTAGE OF SUBJECTS SHOWING IDEAL ALIGNMENT AND DEVIATIONS. INTERRATER RELIABILITY WAS QUANTIFIED USING COHEN KAPPA COEFFICIENT (KAPPA). RESULTS: IN DOWNWARD DOG, THE PREVALENCE OF IDEAL ALIGNMENT WAS 20%, 28%, AND 37%, AT THE NECK, SHOULDER, AND BACK, RESPECTIVELY; KAPPA RANGED FROM .44 TO .69. IN PLANK, THE PREVALENCE OF IDEAL ALIGNMENT WAS 31%, 45%, AND 54% AT THE NECK, SHOULDER, AND BACK, RESPECTIVELY; KAPPA RANGED FROM .47 TO .95. IN SIDE PLANK, THE PREVALENCE OF IDEAL ALIGNMENT WAS 16, 41%, AND 24%, AT THE NECK, SHOULDER, AND BACK, RESPECTIVELY; KAPPA RANGED FROM .20 TO .84. CONCLUSION: THE OBSERVATIONAL SCALE FOUND A HIGH PREVALENCE OF DEVIATIONS, AND DEMONSTRATED FAIR TO SUBSTANTIAL INTERRATER AGREEMENT.	2022	
                                                                                                                                                                                                                                                                                                                                                                 
10 1567  21 MAGNETIC-FREE EXTENDED KALMAN FILTER FOR UPPER LIMB KINEMATIC ASSESSMENT IN YOGA. HUMAN MOTION ANALYSIS IS GAINING INCREASED IMPORTANCE IN SEVERAL FIELDS, FROM MOVEMENT ASSESSMENT IN REHABILITATION TO RECREATIONAL APPLICATIONS SUCH AS VIRTUAL COACHING. AMONG ALL THE TECHNOLOGIES INVOLVED IN MOTION CAPTURE, MAGNETO-INERTIAL MEASUREMENTS UNITS (MIMUS) IS ONE OF THE MOST PROMISING DUE TO THEIR SMALL DIMENSIONS AND LOW COSTS. NEVERTHELESS, THEIR USAGE IS STRONGLY LIMITED BY DIFFERENT ERROR SOURCES, AMONG WHICH MAGNETIC DISTURBANCES, WHICH ARE PARTICULARLY PROBLEMATIC IN INDOOR ENVIRONMENTS. INERTIAL MEASUREMENT UNITS (IMUS) COULD, THUS, BE CONSIDERED AS ALTERNATIVE SOLUTION. INDEED, RELYING EXCLUSIVELY ON ACCELEROMETERS AND GYROSCOPES, THEY ARE INSENSITIVE TO MAGNETIC DISTURBANCES. EVEN IF THE LITERATURE HAS STARTED TO PROPOSE FEW ALGORITHMS THAT DO NOT TAKE INTO ACCOUNT MAGNETOMETER INPUT, THEIR APPLICATION IS LIMITED TO ROBOTICS AND AVIATION. THE AIM OF THE PRESENT WORK IS TO INTRODUCE A MAGNETIC-FREE QUATERNION BASED EXTENDED KALMAN FILTER FOR UPPER LIMB KINEMATIC ASSESSMENT IN HUMAN MOTION (I.E., YOGA). THE ALGORITHM WAS TESTED ON FIVE EXPERT YOGA TRAINERS DURING THE EXECUTION OF THE SUN SALUTATION SEQUENCE. JOINT ANGLE ESTIMATIONS WERE COMPARED WITH THE ONES OBTAINED FROM AN OPTOELECTRONIC REFERENCE SYSTEM BY EVALUATING THE MEAN ABSOLUTE ERRORS (MAES) AND PEARSON'S CORRELATION COEFFICIENTS. THE ACHIEVED WORST-CASE WAS 6.17 DEGREES , WHILE THE BEST ONE WAS 2.65 DEGREES FOR MAES MEAN VALUES. THE ACCURACY OF THE ALGORITHM WAS FURTHER CONFIRMED BY THE HIGH VALUES OF THE PEARSON'S CORRELATION COEFFICIENTS (LOWEST MEAN VALUE OF 0.86).CLINICAL RELEVANCE- THE PROPOSED WORK VALIDATED A MAGNETIC FREE ALGORITHM FOR KINEMATIC RECONSTRUCTION WITH INERTIAL UNITS. IT COULD BE USED AS A WEARABLE SOLUTION TO TRACK HUMAN MOVEMENTS IN INDOOR ENVIRONMENTS BEING INSENSITIVE TO MAGNETIC DISTURBANCES, AND THUS COULD BE POTENTIALLY USED ALSO FOR REHABILITATION PURPOSES.	2021	
                                                                                                                                                                        
11  823  29 EFFECT OF YOGA ON GLUCOSE CONTROL AND QUALITY OF LIFE IN PATIENTS OF PREDIABETES. OBJECTIVE: THE OBJECTIVE OF THIS STUDY WAS TO EVALUATE EFFECT OF YOGA ON FASTING PLASMA GLUCOSE (FPG), POSTPRANDIAL PLASMA GLUCOSE, AND HEMOGLOBIN A1C (HBA1C) AND ALSO ON QUALITY OF LIFE (QOL). RESEARCH DESIGN AND METHODS: THIS WAS A COHORT STUDY IN WHICH 100 DIAGNOSED CASES OF PREDIABETES WERE RECRUITED FOR DOING SPECIFIC YOGA, AND THEY THEMSELVES ACT AS CONTROL FOR THE STUDY. THE MEASUREMENT AND COMPARISON OF FPG, PRANDIAL PLASMA GLUCOSE (PPG), AND HBA1C WERE DONE AT THREE DIFFERENT TIME INTERVALS, THAT IS, BASELINE, 3 MONTHS, AND AT 6 MONTHS. THE ASSESSMENT OF QOL WAS DONE USING SF-36 SCALE. RESULTS: ONE HUNDRED PREDIABETIC CASES WERE SELECTED FOR THE STUDY IN WHICH IMPAIRED FASTING GLUCOSE (IFG) WAS PRESENT MORE IN YOUNGER POPULATION COMPARED TO IMPAIRED GLUCOSE TOLERANCE (IGT) AND IFG PLUS IGT BOTH OF WHICH ARE MORE PREVALENT IN MIDDLE AGE GROUP. THE YOGA THERAPY WAS FOUND TO HAVE FAVORABLE EFFECT ON FPG, PPG, AND HBA1C ALONG WITH VARIOUS ANTHROPOMETRY MEASURES STUDIED IN THIS STUDY. AFTER ADJUSTING CORRELATION COEFFICIENT FOR VARIOUS ANTHROPOMETRY MEASURES, YOGA WAS FOUND TO BE EFFECTIVE FOR CONTROLLING GLYCEMIC PARAMETERS IN PREDIABETICS. CONCLUSIONS: YOGA IS A TYPE OF EXERCISE KNOWN TO IMPROVE GLYCEMIC CONTROL BY CHANGING ANTHROPOMETRY MEASURES, BUT OUR STUDY AIDS IN KNOWLEDGE ABOUT THE BENEFICIAL EFFECT BEYOND THIS KNOWN FACT THROUGH OTHER MECHANISMS YET TO BE EXPLORED.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
12  611  26 DEVELOPMENT OF A YOGA MODULE TARGETING CARDIOVASCULAR HEALTH FOR PATIENTS WITH POST-MYOCARDIAL LEFT VENTRICULAR DYSFUNCTION IN INDIA. BACKGROUND: YOGA IS KNOWN TO CONTRIBUTE TOWARDS CARDIOVASCULAR HEALTH. THIS PAPER DESCRIBES THE DEVELOPMENT OF A NEED-BASED YOGA PROGRAM WHICH IS SUITABLE TO BE INTEGRATED INTO THE CARDIAC REHABILITATION OF POST-MYOCARDIAL INFARCTION PATIENTS WITH LEFT VENTRICULAR DYSFUNCTION. MATERIALS AND METHODS: BASED ON THE ASSESSMENT OF THE NEED OF THE PATIENTS, LITERATURE REVIEW, AND EXPERT OPINION, A YOGA MODULE WAS DEVELOPED USING THE QUALITATIVE METHOD OF INQUIRY. THE PROGRAM INCLUDED WARM-UP EXERCISES, YOGIC ASANAS, PRANAYAMA, MEDITATION AND COUNSELING SESSIONS. A STRUCTURED QUESTIONNAIRE ELICITING COMMENTS ON THE CONTENTS WAS GIVEN INDEPENDENTLY TO TEN EXPERTS WORKING IN THE FIELD OF HEALTH AND YOGA FOR VALIDATION. THE FINAL MODULE WAS DERIVED AFTER INCORPORATING THE SUGGESTIONS OF THE EXPERTS. RESULTS: USING THE RATERS' EXPERTISE IN CARDIOLOGY AND YOGA PRACTICE, THE PRACTICES WHICH CONSTITUTE THE MODULE WERE OPTIMIZED. MAJORITY OF THE EXPERTS (RATERS) AGREED WITH THE DURATION OF 1 H TRAINING FOR 1MONTH UNDER SUPERVISION AS ADEQUATE FOR SUBSEQUENT PRACTICE AT HOME. THERE WAS A 0.786 INTER-RATER RELIABILITY ESTIMATED USING THE INTERCLASS COEFFICIENT (ICC) AND 0.789 INTERNAL CONSISTENCY OF THE QUESTIONS, MEASURED USING CRONBACH'S ALPHA. BOTH VALUES INDICATE "GOOD" RELIABILITY AND CONSISTENCY OF THE YOGA MODULE. CONCLUSION: THE DEVELOPED YOGA MODULE WAS FOUND TO BE ACCEPTABLE. FUTURE RANDOMIZED CONTROL TRIALS WILL BE NECESSARY TO VALIDATE THE EFFECTIVENESS OF THIS MODULE AND IF THE MODULE DEMONSTRATES TO BE EFFECTIVE BY CLINICAL STUDIES, IT MAY ADD A THERAPEUTIC OPTION IN THE REHABILITATION OF PATIENTS WITH HEART FAILURE FOLLOWING MYOCARDIAL INFARCTION, WHICH CAN BE APPLIED IN THE HOSPITALS AND COMMUNITY LEVEL.	2019	
                                                                                                                                                                                                                                                                                           
13 1283  26 GLUTEAL MUSCLE ACTIVATION DURING COMMON YOGA POSES. BACKGROUND: APPROXIMATELY 24% OF PHYSICAL THERAPISTS REPORT REGULARLY USING YOGA TO STRENGTHEN MAJOR MUSCLE GROUPS. ALTHOUGH CLINICIANS AND ATHLETES OFTEN USE YOGA AS A FORM OF STRENGTH TRAINING, LITTLE IS KNOWN ABOUT THE ACTIVATION OF SPECIFIC MUSCLE GROUPS DURING YOGA POSES, INCLUDING THE GLUTEUS MAXIMUS AND MEDIUS. HYPOTHESIS/PURPOSE: THE PURPOSE OF THIS STUDY WAS TO MEASURE GLUTEUS MAXIMIMUS AND GLUTEUS MEDIUS ACTIVATION VIA ELECTROMYOGRAPHY (EMG) DURING FIVE COMMON YOGA POSES. A SECONDARY PURPOSE OF THE CURRENT STUDY WAS TO EXAMINE DIFFERENCES IN MUSCLE ACTIVATION BETWEEN SEXES AND EXPERIENCE LEVELS. STUDY DESIGN: CROSS-SECTIONAL. METHODS: THIRTY-ONE HEALTHY MALES AND FEMALES AGED 18-35 YEARS WERE TESTED DURING FIVE YOGA POSES PERFORMED IN A RANDOMIZED ORDER. SURFACE EMG ELECTRODES WERE PLACED ON SUBJECTS' RIGHT GLUTEUS MAXIMUS AND GLUTEUS MEDIUS. SUBJECTS PERFORMED THE POSES ON BOTH SIDES FOLLOWING A MAXIMAL VOLUNTARY ISOMETRIC CONTRACTION (MVIC) TEST FOR EACH MUSCLE. ALL YOGA POSE EMG DATA WERE NORMALIZED TO THE CORRESPONDING MUSCLE MVIC DATA. RESULTS: HIGHEST GLUTEUS MAXIMUS ACTIVATION OCCURRED DURING HALF MOON POSE ON THE LIFTED/BACK LEG (63.3% MVIC), FOLLOWED BY THE STANCE/FRONT LEG DURING HALF MOON POSE (61.7%), THEN THE LIFTED/BACK LEG DURING WARRIOR THREE POSE (46.1%). HIGHEST GLUTEUS MEDIUS ACTIVATION OCCURRED DURING HALF MOON POSE ON THE LIFTED/BACK LEG (41.9%), FOLLOWED BY THE LIFTED/BACK LEG DURING THE WARRIOR THREE POSE (41.6%). A SIGNIFICANT DIFFERENCE WAS FOUND IN %MVIC OF GLUTEUS MEDIUS ACTIVITY BETWEEN MALE AND FEMALE SUBJECTS (P = 0.026), AND BETWEEN EXPERIENCED AND INEXPERIENCED SUBJECTS (P = 0.050), INDICATING HIGHER ACTIVATION AMONG MALES AND INEXPERIENCED SUBJECTS, RESPECTIVELY. CONCLUSION: HALF MOON POSE AND WARRIOR THREE POSE ELICITED THE HIGHEST ACTIVATION FOR BOTH THE GLUTEUS MAXIMUS AND THE GLUTEUS MEDIUS. HIGHER GLUTEUS MEDIUS ACTIVATION WAS SEEN IN MALES AND INEXPERIENCED SUBJECTS COMPARED TO THEIR FEMALE AND EXPERIENCED COUNTERPARTS. LEVEL OF EVIDENCE: 3.	2021	
                                                                         
14 1610  26 METABOLIC AND VENTILATORY CHANGES DURING AND AFTER HIGH-FREQUENCY YOGA BREATHING. BACKGROUND PRACTICING HIGH-FREQUENCY YOGA BREATHING (HFYB) INDUCED A HYPERMETABOLIC STATE IN A SINGLE SUBJECT DURING THE PRACTICE BUT THE EFFECT HAS NOT BEEN STUDIED IN MULTIPLE PRACTITIONERS. MATERIAL AND METHODS HEALTHY MALE VOLUNTEERS (N=47, GROUP MEAN AGE +/- S.D., 23.2 +/- 4.1 YEARS) WERE RECRUITED AS AN EXPERIMENTAL GROUP AND ANOTHER TWENTY VOLUNTEERS WERE RECRUITED AS A CONTROL GROUP. THE EXPERIMENTAL GROUP PRACTICED EITHER HFYB (BREATH RATE 1.0 HZ) OR BREATH AWARENESS (BAW) ON TWO SEPARATE DAYS. THE SEQUENCE WAS REVERSED FOR ALTERNATE PARTICIPANTS. THE CONTROL GROUP WAS ASSESSED UNDER SIMILAR CONDITIONS WHILE SITTING AT EASE. THE BREATH RATE (RR), TIDAL VOLUME (VT), VENTILATION (VE), VO2, VCO2, ARTERIAL PCO2 AND ENERGY EXPENDITURE (EE KCAL/DAY) WERE ASSESSED FOR 35 MINUTES USING AN OPEN CIRCUIT OXYGEN CONSUMPTION ANALYZER. THE ASSESSMENT PERIOD WAS DIVIDED INTO BEFORE, DURING AND AFTER CONDITIONS. REPEATED MEASURES ANALYSES OF VARIANCE (ANOVA) WERE USED TO COMPARE DATA RECORDED DURING AND AFTER THE TWO PRACTICES WITH DATA RECORDED BEFORE. BEFORE-AFTER COMPARISONS IN THE CONTROL GROUP WERE WITH PAIRED T-TESTS. RESULTS THE MOST RELEVANT SIGNIFICANT CHANGES WERE INCREASES IN VE, VO2, VCO2 AND EE DURING HFYB, WHILE THE SAME VARIABLES DECREASED DURING THE CONTROL PERIOD. HOWEVER AFTER HFYB THERE WAS NO CHANGE IN VO2 OR EE, ALTHOUGH VE DECREASED AS IT DID AFTER THE CONTROL PERIOD. CONCLUSIONS HFYB INDUCES A HYPERMETABOLIC STATE FOR THE DURATION OF THE PRACTICE WHICH RETURNS TO BASELINE AFTER HFYB SUGGESTING A POSSIBLE APPLICATION FOR HFYB IN HYPOMETABOLIC STATES.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
15 1455  27 INFLUENCE OF TIME OF YOGA PRACTICE AND GENDER DIFFERENCES ON BLOOD GLUCOSE LEVELS IN TYPE 2 DIABETES MELLITUS AND NORMAL HEALTHY ADULTS. BACKGROUND: PREVALENCE OF TYPE 2 DIABETES MELLITUS (T2DM) IS INCREASING WORLDWIDE. MANY STUDIES HAVE DEMONSTRATED THE EFFECTIVENESS OF YOGA IN IMPROVING GLYCAEMIC CONTROL, WHEREAS NO STUDIES ARE AVAILABLE SHOWING THE IMPACT OF TIME OF PRACTICE ON GLUCOSE LEVELS. THE CURRENT STUDY EXPLORES THE EFFECT OF TIME OF YOGA PRACTICE ON GLUCOSE LEVELS IN COMMUNITY-DWELLING ADULTS WITH AND WITHOUT T2DM. MATERIALS AND METHODS: A TOTAL OF 189 SUBJECTS WITH T2DM AND 121 SUBJECTS WITHOUT T2DM UNDERWENT A 10-DAY YOGA PROGRAM WHICH INCLUDES PRACTICAL AND THEORY LECTURE SESSIONS FOR 60MIN EVERY DAY, EITHER IN THE MORNING OR EVENING. BASELINE AND POST-INTERVENTION ASSESSMENTS OF FASTING PLASMA GLUCOSE (FPG) WERE MEASURED ON DAY-1 AND DAY-10, RESPECTIVELY. DATA ANALYSIS WERE DONE USING STATISTICAL PACKAGE FOR THE SOCIAL SCIENCES (SPSS), VERSION 16. RESULTS: RESULTS OF THE STUDY SHOWED THAT IN INDIVIDUALS WITH T2DM, A SIGNIFICANTLY HIGHER REDUCTION IN FPG WAS OBSERVED WHILE PRACTICING YOGA IN THE EVENING SESSIONS THAN IN THE MORNING SESSIONS. LIKEWISE, A SIGNIFICANT REDUCTION IN FPG WAS OBSERVED ONLY IN WOMEN WHO PRACTICED YOGA IN THE EVENING THAN IN THE MORNING, IN NON-DIABETIC HEALTHY INDIVIDUALS, WHILE THE REDUCTION WAS NOT STATISTICALLY SIGNIFICANT IN MEN. CONCLUSION: RESULTS OF THIS STUDY SUGGEST THAT REDUCTION IN FPG LEVEL WAS BETTER WHILE PRACTICING YOGA IN EVENING THAN MORNING. SIMILARLY, WOMEN HAD A BETTER REDUCTION IN BLOOD GLUCOSE LEVEL THAN MEN.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
16  410  28 BLOOD LIPIDS AND ANTHROPOMETRIC PARAMETERS IN HEALTHY SUBJECTS PRACTICING YOGA OR RESISTANCE TRAINING IN LEISURE TIME. WHAT MATTERS: TYPE OR INTENSITY OF PHYSICAL ACTIVITY? AIM: THE AIM OF THE PRESENT STUDY WAS TO ASSESS EFFECTS OF YOGA AND RESISTANCE TRAININGS ON BLOOD LIPIDS AND ANTHROPOMETRIC PARAMETERS IN PEOPLE WITHOUT CARDIOVASCULAR DISEASES. MATERIALS AND METHODS: CROSS-SECTIONAL STUDY, WHICH INCLUDED 167 SUBJECTS, WAS CONDUCTED. SUBJECTS REGULARLY PRACTICING YOGA OR RESISTANCE TRAINING NOT LESS THAN 2 TIMES A WEEK FOR A PERIOD MORE THAN ONE YEAR WERE INCLUDED IN THE STUDY. YOGA TRAININGS WERE DEFINED AS YOGA ASANAS AND RESISTANCE TRAININGS WERE DEFINED AS ANY EXERCISE THAT CAUSES THE MUSCLES TO CONTRACT AGAINST AN EXTERNAL RESISTANCE. ANTHROPOMETRIC PARAMETERS, BLOOD LIPIDS AND GLUCOSE, URIC ACID WERE ASSESSED. WE USED INTERNATIONAL QUESTIONNAIRE ON LONG PHYSICAL ACTIVITY TO ASSESS PHYSICAL ACTIVITY AND SEDENTARY TIME. SPSS 17.0 WAS USED TO PERFORM STATISTICAL ANALYSIS. RESULTS: THERE WERE NO SIGNIFICANT DIFFERENCES BETWEEN "YOGA TRAINING" AND "RESISTANCE TRAINING" GROUPS IN GENERAL PHYSICAL ACTIVITY, MODERATE PHYSICAL ACTIVITY AND SITTING TIME IN THE WHOLE GROUP. HDL-CHOLESTEROL WAS SIGNIFICANTLY HIGHER IN "YOGA TRAINING" COMPARED TO "RESISTANCE TRAINING" GROUP AND CONTROL GROUP (1,65+/-0,37 MMOL/L; 1,43+/-0,21 MMOL/L AND 1,34+/-0,22, PYOGA-RESISTANCE TRAINING=0,001; PYOGA-CONTROL=0,0001; PRESISTANCE TRAINING-CONTROL= P2-3=0,037). LDL CHOLESTEROL WAS THE LOWEST IN SUBJECTS THAT HAD THE HIGHEST LEVEL OF VIGOROUS PHYSICAL ACTIVITY. CONCLUSIONS: PEOPLE PRACTICING YOGA AND RESISTANCE TRAINING HAD MORE FAVORABLE BLOOD LIPID PROFILE AND ANTHROPOMETRIC PARAMETERS THAN CONTROL GROUP. "YOGA TRAINING" HAD MORE PRONOUNCED POSITIVE EFFECT ON HDL CHOLESTEROL. LEVEL OF LDL CHOLESTEROL WAS MORE LIKELY TO BE ASSOCIATED WITH INTENSITY OF PHYSICAL ACTIVITY THAN WITH TYPE OF PHYSICAL ACTIVITY.	2021	
                                                                                                                                                                                                                                         
17 1451  17 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  525  15 COMPARISON OF EFFECTS OF YOGA & PHYSICAL EXERCISE IN ATHLETES. THE EFFECT OF PRANAYAMA A CONTROLLED BREATHING PRACTICE, ON EXERCISE TESTS WAS STUDIED IN ATHLETES IN TWO PHASES; SUB-MAXIMAL AND MAXIMAL EXERCISE TESTS. AT THE END OF PHASE I (ONE YEAR) BOTH THE GROUPS (CONTROL AND EXPERIMENTAL) ACHIEVED SIGNIFICANTLY HIGHER WORK RATE AND REDUCTION IN OXYGEN CONSUMPTION PER UNIT WORK. THERE WAS A SIGNIFICANT REDUCTION IN BLOOD LACTATE AND AN INCREASE IN P/L RATIO IN THE EXPERIMENTAL GROUP, AT REST. AT THE END OF PHASE II (TWO YEARS), THE OXYGEN CONSUMPTION PER UNIT WORK WAS FOUND TO BE SIGNIFICANTLY REDUCED AND THE WORK RATE SIGNIFICANTLY INCREASED IN THE EXPERIMENTAL GROUP. BLOOD LACTATE DECREASED SIGNIFICANTLY AT REST IN THE EXPERIMENTAL GROUP ONLY. PYRUVATE AND PYRUVATE-LACTATE RATIO INCREASED SIGNIFICANTLY IN BOTH THE GROUPS AFTER EXERCISE AND AT REST IN THE EXPERIMENTAL GROUP. THE RESULTS IN BOTH PHASES SHOWED THAT THE SUBJECTS WHO PRACTISED PRANAYAMA COULD ACHIEVE HIGHER WORK RATES WITH REDUCED OXYGEN CONSUMPTION PER UNIT WORK AND WITHOUT INCREASE IN BLOOD LACTATE LEVELS. THE BLOOD LACTATE LEVELS WERE SIGNIFICANTLY LOW AT REST.	1994	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
19 1147  29 ENERGY EXPENDITURE DURING A VINYASA YOGA SESSION. BACKGROUND: VINYASA YOGA HAS BEEN RECENTLY PROMOTED AS ONE OF THE MOST POPULAR MINDFUL EXERCISES TO IMPROVE OVERALL HEALTH, INCLUDING BODY WEIGHT MANAGEMENT. THE PURPOSE OF THIS STUDY WAS TO DETERMINE THE METABOLIC RESPONSE OF 24 MODERATELY TRAINED INDIVIDUALS DURING A 90-MIN GROUP VINYASA YOGA ROUTINE. METHODS: HEART RATE (HR) TIME COURSE OF 12 MALES AND 12 FEMALES (AGE: 39+/-7.33 YEARS) WAS RECORDED DURING TWO GROUP VINYASA YOGA SESSIONS CONSISTED OF FOUR SECTIONS (WARM-UP, HIGH-INTENSITY SURYA NAMASKAR (HSN), NO SURYA NAMASKAR POSTURES, AND COOL-DOWN). MAXIMAL OXYGEN UPTAKE (VO<INF>2PEAK</INF>) AND MAXIMUM HR HAD BEEN ESTIMATED EARLIER AFTER A MAXIMAL TREADMILL TEST. VO<INF>2</INF> DURING VINYASA YOGA SESSIONS WAS ESTIMATED FROM INDIVIDUAL REGRESSION EQUATIONS USING THE RELATIONSHIP OF VO<INF>2</INF> AND HR VALUES DERIVED FROM VO<INF>2PEAK</INF> TEST, WHILE THE METABOLIC RATE (KCAL/MIN) WAS CALCULATED FROM THE RELATIONSHIP OF HR AND KCAL/MIN. TOTAL SESSION ENERGY CONSUMPTION WAS THE AVERAGE VALUE OF THE TWO YOGA SESSIONS. RESULTS: THE 2 (GENDER) X 4 (SECTIONS) MIXED ANOVA REVEALED NO SIGNIFICANT INTERACTION BETWEEN THE TWO FACTORS (P=0.101) FOR THE MEAN METABOLIC RATE (7.1+/-2.6 KCAL/MIN). MEAN METABOLIC RATE THOUGHT WAS HIGHER (P=0.015) IN MALES COMPARED TO FEMALES AT EACH SECTION. ALSO, SIGNIFICANT DIFFERENCES WERE FOUND AMONG THE FOUR VINYASA YOGA SECTIONS (P<0.001) IN THE RATE OF ENERGY EXPENDITURE, WITH HSN PRESENTING THE HIGHEST MEAN VALUES (P<0.05). CONCLUSIONS: IT SEEMS THAT SYSTEMATIC PARTICIPATION IN VINYASA YOGA MAY EFFECTIVELY IMPROVE CARDIORESPIRATORY FITNESS AND PROMOTE BODY WEIGHT LOSS, AS AN ALTERNATIVE METHOD TO TRADITIONAL AEROBIC EXERCISE.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                          
20  436  16 CARDIORESPIRATORY AND METABOLIC CHANGES DURING YOGA SESSIONS: THE EFFECTS OF RESPIRATORY EXERCISES AND MEDITATION PRACTICES. THE NOVELTY OF THIS STUDY WAS TO INVESTIGATE THE CHANGES IN CARDIORESPIRATORY AND METABOLIC INTENSITY BROUGHT ABOUT BY THE PRACTICE OF PRANAYAMAS (BREATHING EXERCISES OF YOGA) AND MEDITATION DURING THE SAME HATHA-YOGA SESSION. THE TECHNIQUE APPLIED WAS THE ONE ADVOCATED BY THE HATHA-YOGA SYSTEM. NINE YOGA INSTRUCTORS-FIVE FEMALES AND FOUR MALES, MEAN AGE OF 44+/-11, 6, WERE SUBJECTED TO ANALYSIS OF THE GASES EXPIRED DURING THREE DISTINCT PERIODS OF 30 MIN: REST, RESPIRATORY EXERCISES AND MEDITATIVE PRACTICE. A METABOLIC OPEN CIRCUIT COMPUTERIZED SYSTEM WAS APPLIED (VO2000, MEDGRAPHICS-USA). THE OXYGEN UPTAKE (VO(2)) AND THE CARBON DIOXIDE OUTPUT (VCO(2)) WERE STATISTICALLY DIFFERENT (P <OR= 0.05) DURING MEDITATION AND PRANAYAMA PRACTICES WHEN COMPARED WITH REST. THE HEART RATE ALSO SUFFERED RELEVANT REDUCTIONS WHEN RESULTS AT REST WERE COMPARED WITH THOSE DURING MEDITATION. A SMALLER PROPORTION OF LIPIDS WAS METABOLIZED DURING MEDITATION PRACTICE COMPARED WITH REST. THE RESULTS SUGGEST THAT THE MEDITATION USED IN THIS STUDY REDUCES THE METABOLIC RATE WHEREAS THE SPECIFIC PRANAYAMA TECHNIQUE IN THIS STUDY INCREASES IT WHEN COMPARED WITH THE REST STATE.	2008
