1  967 136 EFFECTS OF AEROBIC EXERCISE TRAINING AND YOGA ON THE BAROREFLEX IN HEALTHY ELDERLY PERSONS. IT IS UNCLEAR WHETHER THE AGE-ASSOCIATED REDUCTION IN BAROREFLEX SENSITIVITY IS MODIFIABLE BY EXERCISE TRAINING. THE EFFECTS OF AEROBIC EXERCISE TRAINING AND YOGA, A NON-AEROBIC CONTROL INTERVENTION, ON THE BAROREFLEX OF ELDERLY PERSONS WAS DETERMINED. BAROREFLEX SENSITIVITY WAS QUANTIFIED BY THE ALPHA-INDEX, AT HIGH FREQUENCY (HF; 0.15-0.35 HZ, REFLECTING PARASYMPATHETIC ACTIVITY) AND MID-FREQUENCY (MF; 0.05-0.15 HZ, REFLECTING SYMPATHETIC ACTIVITY AS WELL), DERIVED FROM SPECTRAL AND CROSS-SPECTRAL ANALYSIS OF SPONTANEOUS FLUCTUATIONS IN HEART RATE AND BLOOD PRESSURE. TWENTY-SIX (10 WOMEN) SEDENTARY, HEALTHY, NORMOTENSIVE ELDERLY (MEAN 68 YEARS, RANGE 62-81 YEARS) SUBJECTS WERE STUDIED. FOURTEEN (4 WOMEN) OF THE SEDENTARY ELDERLY SUBJECTS COMPLETED 6 WEEKS OF AEROBIC TRAINING, WHILE THE OTHER 12 (6 WOMEN) SUBJECTS COMPLETED 6 WEEKS OF YOGA. HEART RATE DECREASED FOLLOWING YOGA (69 +/- 8 VS. 61 +/- 7 MIN-1, P < 0.05) BUT NOT AEROBIC TRAINING (66 +/- 8 VS. 63 +/- 9 MIN-1, P = 0.29). VO2 MAX INCREASED BY 11% FOLLOWING YOGA (P < 0.01) AND BY 24% FOLLOWING AEROBIC TRAINING (P < 0.01). NO SIGNIFICANT CHANGE IN ALPHA MF (6.5 +/- 3.5 VS. 6.2 +/- 3.0 MS MMHG-1, P = 0.69) OR ALPHA HF (8.5 +/- 4.7 VS. 8.9 +/- 3.5 MS MMHG-1, P = 0.65) OCCURRED AFTER AEROBIC TRAINING. FOLLOWING YOGA, ALPHA HF (8.0 +/- 3.6 VS. 11.5 +/- 5.2 MS MMHG-1, P < 0.01) BUT NOT ALPHA MF (6.5 +/- 3.0 VS. 7.6 +/- 2.8 MS MMHG-1, P = 0.29) INCREASED. SHORT-DURATION AEROBIC TRAINING DOES NOT MODIFY THE ALPHA-INDEX AT ALPHA MF OR ALPHA HF IN HEALTHY NORMOTENSIVE ELDERLY SUBJECTS. ALPHA HF BUT NOT ALPHA MF INCREASED FOLLOWING YOGA, SUGGESTING THAT THESE PARAMETERS ARE MEASURING DISTINCT ASPECTS OF THE BAROREFLEX THAT ARE SEPARATELY MODIFIABLE.	1997	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
2 1988  33 SPECTRAL PARAMETERS OF HRV IN YOGA PRACTITIONERS, ATHLETES AND SEDENTARY MALES. PHYSICAL INACTIVITY IS AN IMPORTANT RISK FACTOR FOR CARDIOVASCULAR MORTALITY AND MORBIDITY. EXERCISE IS CONSIDERED AN ACCEPTABLE METHOD FOR IMPROVING AND MAINTAINING PHYSICAL AND EMOTIONAL HEALTH. ALTHOUGH YOGA IS HISTORICALLY A SPIRITUAL DISCIPLINE, A GROWING BODY OF EVIDENCE SUPPORTS THE BELIEF THAT YOGA BENEFITS PHYSICAL AND MENTAL HEALTH. THE OBJECTIVE OF THIS STUDY WAS TO EVALUATE HEART RATE VARIABILITY WHICH REFLECTS AUTONOMIC CONTROL OF HEART AMONG YOGA PRACTITIONERS, ATHLETES AND INDIVIDUALS WITH SEDENTARY LIFESTYLE. THE STUDY WAS CARRIED OUT IN THE DEPARTMENTS OF PHYSIOLOGY AT MAMC AGROHA, HISAR AND PT. BD SHARMA PGIMS ROHTAK, HARYANA. THE STUDY GROUP COMPRISED OF 1200 HEALTHY MALE VOLUNTEERS OF 16 TO 55 YEARS OF AGE. THE STUDY GROUP WAS DIVIDED INTO FOUR AGE GROUPS: GROUP A OF AGE 16 TO 25 YEARS; GROUP B OF AGE 26 TO 35 YEARS; GROUP C OF AGE 36 TO 45 YEARS AND GROUP D OF AGE 46 TO 55 YEARS. ALL AGE GROUPS WERE FURTHER DIVIDED INTO THREE CATEGORIES I.E ATHLETE (RUNNER), YOGA (YOGA PRACTITIONERS) AND SEDENTARY IN WHICH INDIVIDUALS WITH SEDENTARY LIFE STYLE WERE INCLUDED. THE BASAL RECORDING OF ECG IN LEAD II WAS DONE FOR 5 MINUTES. THE POLYRITE-D ECG DATA WAS USED FOR ANALYSIS OF HEART RATE VARIABILITY BY FREQUENCY DOMAIN METHOD. TWO SPECTRAL COMPONENTS WERE RECORDED NAMELY HIGH FREQUENCY (HF) COMPONENT (0.15-0.4 HZ), AN INDICATOR OF VAGAL EFFERENT ACTIVITY AND LOW FREQUENCY (LF) COMPONENT (0.04-.15 HZ), REPLICATOR OF COMPOSITE SYMPATHO-VAGAL INTERPLAY. HF COMPONENT IN NORMALIZED UNIT WAS FOUND SIGNIFICANTLY HIGH IN AGE GROUP B AND C IN YOGA PRACTITIONERS AND ATHLETES AS COMPARED TO SEDENTARY INDIVIDUALS AND IN AGE GROUP D SIGNIFICANTLY HIGH IN YOGA PRACTITIONERS AS COMPARED TO ATHLETES AND SEDENTARY INDIVIDUALS. SIGNIFICANTLY DECREASED LF/HF RATIO WAS FOUND IN AGE GROUP B AND C IN YOGA AND ATHLETE SUBJECTS AS COMPARED TO SEDENTARY INDIVIDUALS AND IN AGE GROUP D IN YOGA PRACTITIONERS AS COMPARED TO ATHLETES AND SEDENTARY INDIVIDUALS. THIS INDICATES THAT PARASYMPATHETIC ACTIVITY IS SUBSTANTIALLY GREATER IN YOGA PRACTITIONERS.	2015	
                                                                                                                                                                             
3  553  36 CORRELATION OF HEART RATE VARIABILITY WITH CAROTID INTIMA MEDIA THICKNESS AFTER 6 MONTH OF YOGA INTERVENTION IN PREDIABETICS. INTRODUCTION: ATHEROSCLEROTIC CAROTID INTIMAMEDIA THICKNESS (CIMT) MAY BE ASSOCIATED WITH ALTERATIONS IN THE AUTONOMIC FUNCTIONS. THE AIM OF THIS STUDY WAS TO INVESTIGATE THE EFFECT OF 6-MONTH YOGA INTERVENTION ON HEART RATE VARIABILITY (HRV) AND CIMT IN ELDERLY SUBJECTS AND THE CORRELATION BETWEEN HRV AND CIMT. METHODOLOGY: THIS WAS A RANDOMIZED CONTROLLED STUDY, IN WHICH A TOTAL OF 250 SUBJECTS WERE ENROLLED. RANDOMIZATION AND ALLOCATION IN YOGA AND CONTROL GROUPS WERE PERFORMED USING COMPUTER-GENERATED RANDOM NUMBERS. THE CIMT WAS DETERMINED BY B-MODE ULTRASONOGRAPHY, AND CARDIAC AUTONOMIC FUNCTION WAS DETERMINED THROUGH FREQUENCY DOMAIN PARAMETER OF HRV MEASURES AT BASELINE AND AFTER 6 MONTHS OF YOGA INTERVENTION. RESULTS: PARTICIPANTS HAD A MEAN AGE OF 45.4 +/- 6.4 YEARS, AND A MEAN CIMT IN CONTROL (0.70 +/- 0.05) AND STUDY GROUP (0.69 +/- 0.073), AND LOW FREQUENCY/HIGH FREQUENCY (LF/HF) RATIO IN CONTROL (2.20 +/- 1.05) AND STUDY GROUP (0.57 +/- 0.54). YOGA GROUP HAD EVIDENCE OF INCREASED VAGAL ACTIVITY IN THE FREQUENCY DOMAIN (HF AND LF/HF RATIO, P < 0.001) WITH RESPECT TO CONTROL GROUP. MOREOVER, A STUDY GROUP SHOWED LOWER INTIMAMEDIA THICKNESS (IMT) THAN CONTROL SUBJECTS (P < 0.01). IN THE WHOLE POPULATION, LF/HF RATIO POSITIVELY AND SIGNIFICANTLY CORRELATED (R = 0.665, P < 0.01) TO IMT. CONCLUSION: THIS STUDY DEMONSTRATED THAT, AFTER YOGA INTERVENTION, LF/HF RATIO IS POSITIVELY CORRELATED WITH CIMT, A PUTATIVE INDEX OF ATHEROSCLEROSIS, CONFIRMING CARDIAC AUTONOMIC NEUROPATHY AS A PART OF THE PATHOPHYSIOLOGICAL PATHWAY FOR ATHEROSCLEROSIS. IT CONFIRMS THAT THE REGULAR YOGA REPRESENTS A VALUABLE STRATEGY TO COUNTER IMPAIRMENTS OF CARDIAC AUTONOMIC ACTIVITY AND ARTERY STRUCTURAL CHANGES.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
4  890  37 EFFECT OF YOGA-BASED CARDIAC REHABILITATION ON HEART RATE VARIABILITY: RANDOMIZED CONTROLLED TRIAL IN PATIENTS POST-MI. AUTONOMIC DYSFUNCTION IS AN INDEPENDENT PREDICTOR OF CARDIOVASCULAR AND ALL-CAUSE MORTALITY AFTER MYOCARDIAL INFARCTION (MI). WE TESTED THE EFFECTS OF A 12-WEEK YOGA-BASED CARDIAC REHABILITATION PROGRAM ON HEART RATE VARIABILITY (HRV) IN 80 PATIENTS POST-MI. THIS RANDOMIZED CONTROLLED TRIAL WITH TWO PARALLEL GROUPS WAS CARRIED OUT IN A TERTIARY CARE INSTITUTION IN INDIA. THE YOGA GROUP RECEIVED 13 HOSPITAL-BASED STRUCTURED YOGA SESSIONS AS AN ADJUNCT TO STANDARD CARE. CONTROL GROUP PARTICIPANTS RECEIVED ENHANCED STANDARD CARE INVOLVING THREE BRIEF EDUCATIONAL SESSIONS WITH A LEAFLET ON THE IMPORTANCE OF DIET AND PHYSICAL ACTIVITY. HRV WAS MEASURED IN ALL PARTICIPANTS WITH LEAD II ELECTROCARDIOGRAM (ECG) SIGNALS. ONE YOGA GROUP PATIENT'S DATA WERE EXCLUDED DUE TO ECG ABNORMALITIES. BASELINE MEASUREMENT WAS DONE 3 WEEKS POST-MI, AND POSTINTERVENTION ASSESSMENT TOOK PLACE AT THE 13TH WEEK. HRV FREQUENCY AND TIME DOMAIN INDICES WERE ANALYZED. THERE WERE NO SIGNIFICANT BETWEEN-GROUP DIFFERENCES IN THE HRV TIME DOMAIN INDICES. FREQUENCY DOMAIN INDICES SHOWED SIGNIFICANT BETWEEN-GROUP DIFFERENCES IN HF POWER (ABSOLUTE) (YOGA VS. CONTROL: 114.42 [-794.80-7,993.78] VS. -38.14 [-4,843.50-1,617.87], P = 0.005) AND TOTAL POWER (NU) (YOGA VS. CONTROL: 44.96 [21.94] VS. -19.55 [15.42], P = 0.01) WITH HIGHER HF POWER AND TOTAL POWER (NU) IN THE YOGA GROUP. IT SHOULD BE NOTED THAT THESE RESULTS CANNOT BE GENERALIZED TO HIGH RISK PATIENTS. RESPIRATORY FREQUENCY CONTROL TO CHECK FOR INFLUENCE OF RESPIRATORY RATE ON RR INTERVAL WAS NOT EVALUATED. THIS SHORT-TERM YOGA-BASED CARDIAC REHABILITATION PROGRAM HAD ADDITIVE EFFECTS IN SHIFTING SYMPATHOVAGAL BALANCE TOWARD PARASYMPATHETIC PREDOMINANCE WHILE INCREASING OVERALL HRV IN OPTIMALLY MEDICATED POST-MI PATIENTS.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                             
5  404  35 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
6  850  35 EFFECT OF YOGA ON SHORT-TERM HEART RATE VARIABILITY MEASURE AS A STRESS INDEX IN SUBJUNIOR CYCLISTS: A PILOT STUDY. SUBJUNIOR ATHLETES EXPERIENCE MENTAL STRESS DUE TO PRESSURE FROM THE COACH, TEACHERS AND PARENTS FOR BETTER PERFORMANCE. STRESS, IF REMAINS FOR LONGER PERIOD AND NOT MANAGED APPROPRIATELY CAN LEADS TO NEGATIVE PHYSICAL, MENTAL AND COGNITIVE IMPACT ON CHILDREN. THE PRESENT STUDY WAS AIMED TO EVALUATE THE EFFECT OF INTEGRATED YOGA MODULE ON HEART RATE VARIABILITY (HRV) MEASURE AS A STRESS INDEX IN SUBJUNIOR CYCLISTS. FAST FURRIER TRANSFORM TECHNIQUE OF FREQUENCY DOMAIN METHOD WAS USED FOR THE ANALYSIS OF HRV. WE HAVE FOUND A SIGNIFICANT INCREASE IN HIGH FREQUENCY (HF) COMPONENT BY 14.64% (P < 0.05) AND DECREASE IN THE LOW FREQUENCY COMPONENT (LF) OF HRV SPECTRUM BY 5.52% (P < 0.05) AND A DECREASE IN LF/HF RATIO BY 19.63% (P < 0.01) IN YOGA GROUP. IN THE CONTROL GROUP, THERE WAS DECREASE IN THE HF COMPONENT AND, NO SIGNIFICANT DIFFERENCE IN THE LF COMPONENT OF HRV SPECTRUM AND LF/HF RATIO. THE RESULTS SHOW THAT YOGA PRACTICE DECREASES SYMPATHETIC ACTIVITY AND CAUSES A SHIFT IN THE AUTONOMIC BALANCE TOWARDS PARASYMPATHETIC DOMINANCE INDICATING A REDUCTION IN STRESS. IN CONCLUSION, YOGA PRACTICE HELPS TO REDUCE STRESS BY OPTIMIZING THE AUTONOMIC FUNCTIONS. SO, IT IS SUGGESTED TO INCORPORATE YOGA MODULE AS A REGULAR FEATURE TO KEEP SUBJUNIOR ATHLETES BOTH MENTALLY AND PHYSICALLY FIT.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
7 1027  26 EFFECTS OF YOGA BREATHING PRACTICE ON HEART RATE VARIABILITY IN HEALTHY ADOLESCENTS: A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: THIS STUDY WAS CONDUCTED AMONG HEALTHY ADOLESCENTS TO ASSESS THE EFFECTS OF A YOGA BREATHING PRACTICE (BHRAMARI PRANAYAMA, BHR.P) TOWARDS CARDIAC AUTONOMIC FUNCTION USING HEART RATE VARIABILITY (HRV) PARAMETERS. METHODS: OF THE 730 ELIGIBLE SUBJECTS SCREENED, 520 HEALTHY ADOLESCENTS WHO MET THE INCLUSION AND EXCLUSION CRITERIA WERE RANDOMLY ASSIGNED TO EITHER YOGA BREATHING GROUP (N=260) OR CONTROL GROUP (N=260). THE YOGA BREATHING GROUP PRACTICED BHR.P. FIVE DAYS A WEEK FOR A DURATION OF SIX MONTHS WHILE THE CONTROL GROUP CONTINUED WITH THEIR DAILY ROUTINE WITHOUT ANY INTERVENTION. OUTCOME MEASURES WERE TIME AND FREQUENCY DOMAIN OF HRV IN BOTH GROUPS WHICH WERE ASSESSED BEFORE AND AFTER THE INTERVENTION USING LEAD II ECG. LINEAR MODELS WERE USED IN THE ANALYSIS OF SHORT TERM HRV. RESULTS: AFTER 6 MONTHS OF YOGA BREATHING, THE TIME DOMAIN PARAMETERS OF SHORT TERM HRV SHOWED SIGNIFICANT (P<0.05) IMPROVEMENT TOWARDS THE PARASYMPATHETIC DOMAIN. FREQUENCY DOMAIN PARAMETERS ALSO SHOWED THE SAME DIRECTION OF CHANGES. IN CONTRAST, CONTROL GROUP SUBJECTS SHOWED A TREND TOWARDS A SYMPATHETIC DOMAIN. CONCLUSION: THE PRESENT STUDY SHOWED A POSITIVE SHIFT IN CARDIAC AUTONOMIC MODULATION TOWARDS PARASYMPATHETIC PREDOMINANCE AFTER 6 MONTHS OF YOGA BREATHING PRACTICE AMONG APPARENTLY HEALTHY ADOLESCENTS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
8  295  28 AGE RELATED DIFFERENCES OF SELECTED HATHA YOGA PRACTICES ON ANTHROPOMETRIC CHARACTERISTICS, MUSCULAR STRENGTH AND FLEXIBILITY OF HEALTHY INDIVIDUALS. BACKGROUND: PHYSIOLOGICAL BENEFITS OF YOGA ON VOLUNTEERS OF A PARTICULAR AGE GROUP ARE AVAILABLE. HOWEVER, REPORTS ON EFFICACY OF A SPECIFIC YOGA PACKAGE ON THE POPULACE OF DIFFERENT AGE GROUPS FROM SIMILAR OCCUPATIONAL BACKGROUND IS STILL VERY LIMITED. THEREFORE, THE PRESENT STUDY WAS CONDUCTED TO APPRAISE THE EFFECT OF A SPECIFIC HATHA YOGA PACKAGE ON ANTHROPOMETRIC CHARACTERISTICS, FLEXIBILITY AND MUSCULAR STRENGTH OF HEALTHY INDIVIDUALS OF DIFFERENT AGE GROUPS FROM SIMILAR OCCUPATIONAL TRADE. MATERIALS AND METHODS: A TOTAL OF 71 PARTICIPANTS (GROUP ALL) FROM INDIAN AIR FORCE GROUND PERSONNEL VOLUNTEERED AND AGE WISE DIVIDED INTO 3 GROUPS - (I) GROUP I (GR. - I) (N1 = 27, 20-29 YEARS), (II) GROUP II (GR. - II) (N2 = 21, 30-39 YEARS) AND (III) GROUP III (GR. - III) (N3 = 23, 40-49 YEARS). ALL THE PARTICIPANTS UNDERGONE SELECTED HATHA YOGA TRAINING FOR 1 H DAILY FOR A PERIOD OF 12 WEEKS. PARAMETERS WERE RECORDED BEFORE AND AFTER THE TRAINING. PRE AND POST TRAINING DIFFERENCES WERE ASSESSED BY STUDENT'S T-TEST. RESULTS: BODY WEIGHT (ALL, GR. - II AND GR. - III [ALL P < 0.05]), BODY MASS INDEX (GR. - II AND GR. - III [BOTH P < 0.01]) AND FAT% (GR. - II AND III [BOTH P < 0.05]) WERE DECREASED SIGNIFICANTLY. NECK CIRCUMFERENCE WAS INCREASED SIGNIFICANTLY IN GR. - I (P < 0.05) BUT DECREASED SIGNIFICANTLY IN GR. - III (P < 0.05). CHEST CIRCUMFERENCE (ALL (P < 0.001), IN GR. - I AND II [BOTH P < 0.05]), GRIP STRENGTH (ALL [LEFT: P < 0.01 AND RIGHT: P < 0.05], IN GR. - I [LEFT: P < 0.05 AND RIGHT: P < 0.01], IN GR. - II [RIGHT: P < 0.05] AND IN GR. - III [LEFT: P < 0.05 AND RIGHT: P < 0.01]), BACK LEG STRENGTH (GROUP WISE P < 0.001, P < 0.05, P < 0.01 AND P < 0.05 RESPECTIVELY) AND FLEXIBILITY (ALL P < 0.001) WERE INCREASED SIGNIFICANTLY. SUMMARY AND CONCLUSION: HATHA YOGA CAN IMPROVE ANTHROPOMETRIC CHARACTERISTICS, MUSCULAR STRENGTH AND FLEXIBILITY AMONG VOLUNTEERS OF DIFFERENT AGE GROUP AND CAN ALSO BE HELPFUL IN PREVENTING AND ATTENUATING AGE RELATED DETERIORATION OF THESE PARAMETERS.	2015	
                                                                                                                                                            
9 2823  29 YOGA VERSUS AEROBIC ACTIVITY: EFFECTS ON SPIROMETRY RESULTS AND MAXIMAL INSPIRATORY PRESSURE. OBJECTIVE: TO CLARIFY WHETHER, IN HEALTHY INDIVIDUALS, PRACTICING YOGA CAN MODIFY MAXIMAL INSPIRATORY PRESSURE AND SPIROMETRIC INDICES WHEN COMPARED WITH THE PRACTICE OF AEROBIC EXERCISE. MEYHODS: A CONTROLLED CLINICAL TRIAL. A TOTAL OF 31 HEALTHY VOLUNTEERS WERE ALLOCATED TO PRACTICE AEROBIC EXERCISE (N = 15) OR TO PRACTICE YOGA (N = 16). THOSE IN THE FIRST GROUP SERVED AS CONTROLS AND ENGAGED IN AEROBIC EXERCISE FOR 45-60 MINUTES, TWICE A WEEK FOR THREE MONTHS. THOSE IN THE SECOND GROUP PRACTICED SELECTED YOGIC TECHNIQUES, ALSO IN SESSIONS OF 45-60 MINUTES, TWICE A WEEK FOR THREE MONTHS. FORCED VITAL CAPACITY, FORCED EXPIRATORY VOLUME IN ONE SECOND AND MAXIMAL INSPIRATORY PRESSURE WERE MEASURED BEFORE AND AFTER THE THREE MONTHS OF TRAINING. RESULTS: NO SIGNIFICANT ALTERATIONS WERE SEEN IN THE SPIROMETRIC INDICES. A SLIGHT, ALTHOUGH NOT SIGNIFICANT, IMPROVEMENT IN MAXIMAL INSPIRATORY PRESSURE WAS SEEN IN BOTH GROUPS. HOWEVER, THERE WAS A SIGNIFICANT DIFFERENCE, SEEN IN BOTH GENDERS, BETWEEN THE ABSOLUTE DELTA (FINAL VALUE MINUS BASELINE VALUE) OF MAXIMAL INSPIRATORY PRESSURE FOR THE GROUP PRACTICING YOGA AND THAT OBTAINED FOR THE GROUP ENGAGING IN AEROBIC EXERCISE (MALES: 19.5 CM H2O VERSUS 2.8 CM H2O, P = 0.05; FEMALES: 20 CM H2O VERSUS 3.9 CM H2O, P = 0.01). CONCLUSION: NEITHER YOGA NOR AEROBIC EXERCISE PROVIDED A STATISTICALLY SIGNIFICANT IMPROVEMENT IN MAXIMAL INSPIRATORY PRESSURE AFTER THREE MONTHS. HOWEVER, THE ABSOLUTE VARIATION IN MAXIMAL INSPIRATORY PRESSURE WAS GREATER AMONG THOSE PRACTICING YOGA.	2006	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
10  412  28 BLOOD PRESSURE EFFECTS OF YOGA, ALONE OR IN COMBINATION WITH LIFESTYLE MEASURES: RESULTS OF THE LIFESTYLE MODIFICATION AND BLOOD PRESSURE STUDY (LIMBS). THE AUTHORS CONDUCTED A STUDY TO ASSESS THE EFFECTS OF YOGA ON BLOOD PRESSURE (BP). PATIENTS WERE RANDOMIZED TO YOGA (BLOOD PRESSURE EDUCATION PROGRAM [BPEP]), OR A COMBINED PROGRAM (COMBO). AMBULATORY BP WAS MEASURED AT BASELINE AND AT 12 AND 24 WEEKS. DATA ARE PRESENTED FOR ALL ENROLLED PATIENTS (N=137) AND FOR COMPLETERS ONLY (N=90). SYSTOLIC BP (SBP) AND DIASTOLIC BP (DBP) WERE SIGNIFICANTLY DECREASED WITHIN ALL GROUPS AT 12 AND 24 WEEKS (P<.001) FOR ENROLLED PATIENTS AND COMPLETERS. SBP WAS SIGNIFICANTLY REDUCED IN THE YOGA AND COMBO GROUPS AS COMPARED WITH THE BPEP GROUP AT 12 WEEKS IN ALL ENROLLED AND COMPLETERS. SBP DIFFERENCES WERE NO LONGER SIGNIFICANT AT 24 WEEKS BETWEEN GROUPS IN ALL ENROLLED PATIENTS; HOWEVER, THERE WAS A GREATER REDUCTION IN SBP AT 24 WEEKS IN COMPLETERS FAVORING BPEP OVER YOGA. NO DIFFERENCES IN DBP BETWEEN GROUPS OR IN BP BETWEEN THE YOGA AND COMBO GROUPS WERE PRESENT. THE AUTHORS DID NOT OBSERVE AN ADDITIVE BENEFIT FROM COMBINING YOGA WITH BPEP MEASURES. REASONS FOR THIS ARE UNCLEAR AT THIS TIME. BP LOWERING WITH YOGA, HOWEVER, WAS SIMILAR TO THAT ACHIEVED WITH LIFESTYLE MEASURES.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
11 2775  40 YOGA RESPIRATORY TRAINING IMPROVES RESPIRATORY FUNCTION AND CARDIAC SYMPATHOVAGAL BALANCE IN ELDERLY SUBJECTS: A RANDOMISED CONTROLLED TRIAL. OBJECTIVES: SINCE AGEING IS ASSOCIATED WITH A DECLINE IN PULMONARY FUNCTION, HEART RATE VARIABILITY AND SPONTANEOUS BAROREFLEX, AND RECENT STUDIES SUGGEST THAT YOGA RESPIRATORY EXERCISES MAY IMPROVE RESPIRATORY AND CARDIOVASCULAR FUNCTION, WE HYPOTHESISED THAT YOGA RESPIRATORY TRAINING MAY IMPROVE RESPIRATORY FUNCTION AND CARDIAC AUTONOMIC MODULATION IN HEALTHY ELDERLY SUBJECTS. DESIGN: 76 HEALTHY ELDERLY SUBJECTS WERE ENROLLED IN A RANDOMISED CONTROL TRIAL IN BRAZIL AND 29 COMPLETED THE STUDY (AGE 68 +/- 6 YEARS, 34% MALES, BODY MASS INDEX 25 +/- 3 KG/M(2)). SUBJECTS WERE RANDOMISED INTO A 4-MONTH TRAINING PROGRAM (2 CLASSES/WEEK PLUS HOME EXERCISES) OF EITHER STRETCHING (CONTROL, N=14) OR RESPIRATORY EXERCISES (YOGA, N=15). YOGA RESPIRATORY EXERCISES (BHASTRIKA) CONSISTED OF RAPID FORCED EXPIRATIONS FOLLOWED BY INSPIRATION THROUGH THE RIGHT NOSTRIL, INSPIRATORY APNOEA WITH GENERATION OF INTRATHORACIC NEGATIVE PRESSURE, AND EXPIRATION THROUGH THE LEFT NOSTRIL. PULMONARY FUNCTION, MAXIMUM EXPIRATORY AND INSPIRATORY PRESSURES (PE(MAX) AND PI(MAX), RESPECTIVELY), HEART RATE VARIABILITY AND BLOOD PRESSURE VARIABILITY FOR SPONTANEOUS BAROREFLEX DETERMINATION WERE DETERMINED AT BASELINE AND AFTER 4 MONTHS. RESULTS: SUBJECTS IN BOTH GROUPS HAD SIMILAR DEMOGRAPHIC PARAMETERS. PHYSIOLOGICAL VARIABLES DID NOT CHANGE AFTER 4 MONTHS IN THE CONTROL GROUP. HOWEVER, IN THE YOGA GROUP, THERE WERE SIGNIFICANT INCREASES IN PE(MAX) (34%, P<0.0001) AND PI(MAX) (26%, P<0.0001) AND A SIGNIFICANT DECREASE IN THE LOW FREQUENCY COMPONENT (A MARKER OF CARDIAC SYMPATHETIC MODULATION) AND LOW FREQUENCY/HIGH FREQUENCY RATIO (MARKER OF SYMPATHOVAGAL BALANCE) OF HEART RATE VARIABILITY (40%, P<0.001). SPONTANEOUS BAROREFLEX DID NOT CHANGE, AND QUALITY OF LIFE ONLY MARGINALLY INCREASED IN THE YOGA GROUP. CONCLUSION: RESPIRATORY YOGA TRAINING MAY BE BENEFICIAL FOR THE ELDERLY HEALTHY POPULATION BY IMPROVING RESPIRATORY FUNCTION AND SYMPATHOVAGAL BALANCE.

12 1473  23 INSULIN SENSITIVITY AND CARDIAC AUTONOMIC FUNCTION IN YOUNG MALE PRACTITIONERS OF YOGA. BACKGROUND: WHILE YOGA IS THOUGHT TO REDUCE THE RISK OF CHRONIC NON-COMMUNICABLE DISEASES SUCH AS DIABETES, THERE ARE NO STUDIES ON INSULIN SENSITIVITY IN LONG TERM PRACTITIONERS OF YOGA. WE ASSESSED INSULIN SENSITIVITY AND CARDIAC AUTONOMIC FUNCTION IN LONG TERM PRACTITIONERS OF YOGA. METHODS: FIFTEEN HEALTHY, YOUNG, MALE PRACTITIONERS OF YOGA WERE COMPARED WITH 15 YOUNG, HEALTHY MALES WHO DID NOT PRACTICE YOGA MATCHED FOR BODY-MASS INDEX. FASTING INSULIN SENSITIVITY WAS MEASURED IN THE FASTING STATE BY THE HYPERINSULINAEMIC-EUGLYCAEMIC CLAMP. RESULTS: THERE WERE NO SIGNIFICANT DIFFERENCES BETWEEN THE GROUPS IN THEIR ANTHROPOMETRY OR BODY COMPOSITION. HOWEVER, THE FASTING PLASMA INSULIN WAS SIGNIFICANTLY LOWER IN THE YOGA GROUP. THE YOGA GROUP WAS ALSO MORE INSULIN SENSITIVE (YOGA 7.82 [2.29] V. CONTROL 4.86 [11.97] (MG/[KG.MIN])/(MICROU/ML), P < 0.001). WHILE THE BODY WEIGHT AND WAIST CIRCUMFERENCE WERE NEGATIVELY CORRELATED WITH GLUCOSE DISPOSAL RATE IN THE CONTROLS, THERE WERE NO SIMILAR CORRELATIONS IN THE YOGA GROUP. THE YOGA GROUP HAD SIGNIFICANTLY HIGHER LOW-FREQUENCY POWER AND LOWER NORMALIZED HIGH-FREQUENCY POWER. CONCLUSION: LONG TERM YOGA PRACTICE (FOR 1 YEAR OR MORE) IS ASSOCIATED WITH INCREASED INSULIN SENSITIVITY AND ATTENUATES THE NEGATIVE RELATIONSHIP BETWEEN BODY WEIGHT OR WAIST CIRCUMFERENCE AND INSULIN SENSITIVITY.	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
13 2745  29 YOGA PRACTICE IMPROVES THE BODY MASS INDEX AND BLOOD PRESSURE: A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: YOGA, AN ANCIENT INDIAN SYSTEM OF EXERCISE AND THERAPY IS AN ART OF GOOD LIVING OR AN INTEGRATED SYSTEM FOR THE BENEFIT OF THE BODY, MIND, AND INNER SPIRIT. REGULAR PRACTICE OF YOGA CAN HELP TO INCREASE BLOOD FLOW TO THE BRAIN, REDUCE STRESS, HAVE A CALMING EFFECT ON THE NERVOUS SYSTEM, AND GREATLY HELP IN REDUCING HYPERTENSION. AIM: AIM OF THE PRESENT STUDY IS TO EVALUATE THE EFFECT OF 1-MONTH YOGA PRACTICE ON BODY MASS INDEX (BMI), AND BLOOD PRESSURE (BP). MATERIALS AND METHODS: THE PRESENT STUDY WAS CONDUCTED TO DETERMINE THE EFFECT OF YOGA PRACTICE ON 64 PARTICIPANTS (AGE 53.6 +/- 13.1 YEARS) (EXPERIMENTAL GROUP) WHEREAS THE RESULTS WERE COMPARED WITH 26 HEALTHY VOLUNTEERS (CONTROL GROUP). WE EXAMINED THE EFFECTS OF YOGA ON PHYSIOLOGICAL PARAMETERS IN A 1-MONTH PILOT STUDY. MOST OF THE PARTICIPANTS WERE LEARNER AND PRACTICED YOGA FOR 1 H DAILY IN THE MORNING FOR 1 MONTH. BMI AND BP (SYSTOLIC AND DIASTOLIC) WERE STUDIED BEFORE AND AFTER 1 MONTH OF YOGA PRACTICE. RESULTS: YOGA PRACTICE CAUSES DECREASED BMI (26.4 +/- 2.5-25.22 +/- 2.4), SYSTOLIC BP (136.9 +/- 22.18 MMHG TO 133 +/- 21.38 MMHG), AND DIASTOLIC BP (84.7 +/- 6.5 MMHG TO 82.34 +/- 7.6 MMHG). ON THE OTHER HAND, NO SIGNIFICANT CHANGES WERE OBSERVED IN BMI AND BP OF CONTROL GROUP. CONCLUSION: THIS STUDY CONCLUDES THAT YOGA PRACTICE HAS POTENTIAL TO CONTROL BMI AND BP WITHOUT TAKING ANY MEDICATION.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
14 1388  31 IMPACT OF SHORT-TERM PRACTICE OF YOGA ON HEART RATE VARIABILITY. BACKGROUND: YOGA IS A SCIENCE THAT FACILITATES HOMEOSTASIS, AN ANCIENT WAY OF LIFE INTENDED TO IMPROVE THE QUALITY OF LIFE OF AN INDIVIDUAL. PRACTICE OF YOGA IS PROPOSED TO ALTER THE AUTONOMIC NERVOUS SYSTEM AND AFFECT THE CARDIOVASCULAR FUNCTIONING. THIS STUDY WAS INTENDED TO ASSESS THE INFLUENCE OF SHORT-TERM PRACTICE OF YOGA FOR A MONTH ON HEART RATE VARIABILITY (HRV). MATERIALS AND METHODS: TOTALLY, 40 HEALTHY MALE VOLUNTEERS IN THE AGE GROUP OF 30-60 YEARS WILLING TO PRACTICE YOGA FOR A MONTH WERE INCLUDED IN THE STUDY. HRV WAS ASSESSED USING HRV DEVICE (RMS VAGUS, INDIA). PREINTERVENTIONAL ASSESSMENT OF HRV WAS DONE IN THESE SUBJECTS. PRACTICE OF YOGA THAT INCLUDED A SET OF PHYSICAL POSTURES (ASANAS), BREATHING TECHNIQUES (PRANAYAMA), AND MEDITATION (DHYANA) WERE PERFORMED FOR AN HOUR DAILY FOR 1 MONTH UNDER THE GUIDANCE OF A CERTIFIED YOGA INSTRUCTOR. POSTINTERVENTIONAL ASSESSMENT OF HRV WAS DONE. THE VALUES WERE EXPRESSED IN MEDIAN AND THEIR INTERQUARTILE RANGE, AND STATISTICAL ANALYSIS WAS DONE TO COMPARE THE CHANGES USING WILCOXON SIGNED RANK TEST. RESULTS: THIRTY-TWO OF 40 SUBJECTS RECRUITED FOR YOGA PRACTICE COMPLETED THE STUDY PROTOCOL. ANALYSIS OF HRV REVEALED THAT IN TIME DOMAIN PARAMETERS, SDNN INCREASED FROM 33.60 (31.41-44.82) TO 42.11 (34.43-57.51), RMSSD INCREASED FROM 22.00 (16.00-33.80) TO 25.6 (17.0-34.8), AND PNN50 INCREASED FROM 2.45 (0.80-15.38) TO 7.35 (1.40-18.57) AFTER INTERVENTION. IN THE FREQUENCY DOMAIN PARAMETERS, THE LOW-FREQUENCY (LF) POWER SPECTRUM REDUCED FROM 39.30 (25.1-46.25) TO 30.40 (22.75-40.62) AND LF/HIGH-FREQUENCY RATIO WAS REDUCED FROM 2.62 (1.91-4.07) TO 2.28 (1.4-3.07) AFTER 1 MONTH PRACTICE OF YOGA. P < 0.05 WAS CONSIDERED STATISTICALLY SIGNIFICANT. CONCLUSION: AUTONOMIC BALANCE TILTS TOWARD PARASYMPATHETIC PREDOMINANCE AFTER 1 MONTH PRACTICE OF YOGA.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                        
15  814  25 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
16  492  27 COGNITIVE BEHAVIOR EVALUATION BASED ON PHYSIOLOGICAL PARAMETERS AMONG YOUNG HEALTHY SUBJECTS WITH YOGA AS INTERVENTION. OBJECTIVE: TO INVESTIGATE THE EFFECT OF YOGA PRACTICE ON COGNITIVE SKILLS, AUTONOMIC NERVOUS SYSTEM, AND HEART RATE VARIABILITY BY ANALYZING PHYSIOLOGICAL PARAMETERS. METHODS: THE STUDY WAS CONDUCTED ON 30 NORMAL YOUNG HEALTHY ENGINEERING STUDENTS. THEY WERE RANDOMLY SELECTED INTO TWO GROUPS: YOGA GROUP AND CONTROL GROUP. THE YOGA GROUP PRACTICED YOGA ONE AND HALF HOUR PER DAY FOR SIX DAYS IN A WEEK, FOR A PERIOD OF FIVE MONTHS. RESULTS: THE YOGA PRACTISING GROUP SHOWED INCREASED ALPHA, BETA, AND DELTA EEG BAND POWERS AND SIGNIFICANT REDUCTION IN THETA AND GAMMA BAND POWERS. THE INCREASED ALPHA AND BETA POWER CAN REPRESENT ENHANCED COGNITIVE FUNCTIONS SUCH AS MEMORY AND CONCENTRATION, AND THAT OF DELTA SIGNIFIES SYNCHRONIZATION OF BRAIN ACTIVITY. THE HEART RATE INDEX THETA/ALPHA DECREASED, NEURAL ACTIVITY BETA/THETA INCREASED, ATTENTION RESOURCE INDEX BETA/(ALPHA + THETA) INCREASED, EXECUTIVE LOAD INDEX (DELTA + THETA)/ALPHA DECREASED, AND THE RATIO (DELTA + THETA)/(ALPHA + BETA) DECREASED. THE YOGA PRACTICE GROUP SHOWED IMPROVEMENT IN HEART RATE VARIABILITY, INCREASED SDNN/RMSSD, AND REDUCTION IN LF/HF RATIO. CONCLUSION: YOGA PRACTISING GROUP SHOWED SIGNIFICANT IMPROVEMENT IN VARIOUS COGNITIVE FUNCTIONS, SUCH AS PERFORMANCE ENHANCEMENT, NEURAL ACTIVITY, ATTENTION, AND EXECUTIVE FUNCTION. IT ALSO RESULTED IN INCREASE IN THE HEART RATE VARIABILITY, PARASYMPATHETIC NERVOUS SYSTEM ACTIVITY, AND BALANCED AUTONOMIC NERVOUS SYSTEM REACTIVITY.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
17 1301  27 HATHA YOGA ON BODY BALANCE. BACKGROUND: A GOOD BODY BALANCE REQUIRES A PROPER FUNCTION OF VESTIBULAR, VISUAL, AND SOMATOSENSORY SYSTEMS WHICH CAN BE REACH WITH EXERCISE PRACTICE AND/OR YOGA. AIM: TO DETERMINE THE EFFECTS OF A 5-MONTH HATHA YOGA TRAINING PROGRAM ON BODY BALANCE IN YOUNG ADULTS. MATERIALS AND METHODS: THIS STUDY USED A CONTROLLED, NONRANDOMIZED DESIGN, WHERE THE EXPERIMENTAL GROUP UNDERWENT A 5-MONTH TRAINING PROGRAM AND WERE THEN COMPARED WITH THE CONTROL GROUP THAT HAD A SEDENTARY LIFESTYLE. A CONVENIENCE SAMPLE OF 34 OUT OF 40 MEN AGED 25-55 YEARS OLD (34.0 +/- 0.9) WERE DEEMED ELIGIBLE FOR THIS STUDY. THEY WERE RANDOMLY DIVIDED INTO TWO GROUPS: EXPERIMENTAL AND CONTROL GROUPS. SUBJECTS IN THE EXPERIMENTAL GROUP WERE ENGAGED IN 60 MIN SESSIONS OF HATHA YOGA THREE TIMES A WEEK FOR 5 MONTHS. WE EVALUATED POSTURAL CONTROL BY MEASURING THE LIMIT OF STABILITY AND VELOCITY OF OSCILLATION (VOS) IN THREE CONDITIONS OF THE BALANCE REHABILITATION UNIT (BRU) AND THROUGH FIELD PROCEDURES (FOUR POSITION, PLANE, FLAMINGO, HOPSCOTCH, AND DYNAMIC TEST). RESULTS: WE OBSERVED DIFFERENCES (P < 0.05) IN POSTINTERVENTION SCORES BETWEEN THE GROUPS REGARDLESS OF BRU PARAMETERS AND FIELD PROCEDURES (EXCEPT FOR FLAMINGO) EVEN AFTER ADJUSTING FOR PREINTERVENTION SCORES, SUGGESTING THAT THESE CHANGES WERE INDUCED BY HATHA YOGA TRAINING. THE PARTIAL ETA SQUARED ON BRU PARAMETERS RANGED FROM 0.78 (VOS1)-0.97 (COP2), AND FROM 0.00 (FLAMINGO)-0.94 (FOUR POSITION) FOR THE FIELD PROCEDURES. CONCLUSIONS: OUR RESULTS PROVIDE SUBSTANTIAL EVIDENCE THAT POSTURAL CONTROL IN HEALTHY YOUNG ADULTS CAN BE IMPROVED THROUGH PRACTICING HATHA YOGA.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
18 2817  37 YOGA TRAINING IMPROVES QUALITY OF LIFE IN WOMEN WITH ASTHMA. OBJECTIVES: INDIVIDUALS WITH ASTHMA FREQUENTLY SUFFER WITH A DECREASE IN QUALITY OF LIFE. YOGA HAS BEEN SHOWN TO IMPROVE AUTONOMIC FUNCTION IN THE HEALTHY POPULATION AND HAS BEEN USED AS AN ALTERNATIVE THERAPY TO HELP IMPROVE SYMPTOMS ASSOCIATED WITH VARIOUS DISEASES. PURPOSE: THE PURPOSE OF THIS STUDY WAS TO ASSESS WHETHER 10 WEEKS OF YOGA TRAINING CAN IMPROVE QUALITY OF LIFE AND HEART RATE VARIABILITY (HRV) IN PATIENTS WITH ASTHMA. DESIGN: NINETEEN (19) FEMALES WERE RANDOMLY ASSIGNED TO A YOGA GROUP OR A CONTROL GROUP FOR A 10-WEEK INTERVENTION WHILE STILL FOLLOWING GUIDELINES ESTABLISHED BY THEIR PHYSICIAN. ALL SUBJECTS ANSWERED THE ST. GEORGE'S RESPIRATORY QUESTIONNAIRE (SGRQ) TO ASSESS QUALITY OF LIFE AND PERFORMED AN ISOMETRIC HANDGRIP EXERCISE TEST TO ASSESS HRV. RESULTS: BASED ON THE SGRQ, SIGNIFICANT IMPROVEMENTS (45%, P < 0.05) IN QUALITY OF LIFE WERE OBSERVED WITH THE YOGA TRAINING, WHILE NO CHANGES WERE FOUND IN THE CONTROL GROUP. RESTING HEMODYNAMIC MEASURES IMPROVED SIGNIFICANTLY IN THE YOGA GROUP COMPARED TO THE CONTROL GROUP (P < 0.05). THE YOGA GROUP DECREASED PARASYMPATHETIC MODULATION (HFNU [NORMALIZED UNITS]) PRE- TO POSTINTERVENTION (0.45 +/- 0.60 TO 0.35 +/- 0.06 NU, P<0.05, RESPECTIVELY) IN RESPONSE TO THE ISOMETRIC FOREARM EXERCISE (IFE), WHEREAS THE CONTROL GROUP DID NOT CHANGE. ADDITIONALLY, THE YOGA GROUP INCREASED SYMPATHETIC (LFNU) (PRE 0.47 +/- 0.07 TO POST 0.60 +/- 0.07 NU, P < 0.05) AND SYMPATHOVAGAL MODULATION (LOGLF/HF) (PRE 4.61 +/- 0.39 TO POST 5.31 +/- 0.44, P < 0.05, RESPECTIVELY) DURING IFE WITH NO CHANGE IN THE CONTROL GROUP. CONCLUSIONS: YOGA TRAINING IMPROVED QUALITY OF LIFE IN WOMEN WITH MILD-TO-MODERATE ASTHMA AND RESULTED IN DECREASED PARASYMPATHETIC AND INCREASED SYMPATHETIC MODULATION IN RESPONSE TO AN IFE.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
19  771  29 EFFECT OF YOGA AND AEROBICS EXERCISE ON SLEEP QUALITY IN WOMEN WITH TYPE 2 DIABETES: A RANDOMIZED CONTROLLED TRIAL. OBJECTIVE: THE AIM OF THIS STUDY WAS INVESTIGATING THE EFFECT OF 12 WEEKS OF YOGA AND AEROBIC EXERCISE (RUNNING ON A TREADMILL) ON THE SLEEP QUALITY IN WOMEN WITH TYPE 2 DIABETES. MATERIALS AND METHODS: 39 DIABETIC WOMEN WERE SELECTED FROM SEMNAN CITY WITH THE MEAN AGE OF 46.85+/-3.35 YEARS, WEIGHT OF 69.79+/-17.18 KG, HEIGHT OF 155.03+/-5.00, BMI OF 29.64+/-5.00 KG/M(2) WHO HAD A BACKGROUND OF DIABETES FOR 6.46+/-2.69 YEARS. THEY WERE THEN RANDOMLY DIVIDED INTO YOGA EXERCISE (N=15), AEROBIC EXERCISE (N=13), AND CONTROL GROUP (N=11). THE EXERCISE PROGRAM WAS PERFORMED FOR 12 WEEKS, THREE SESSIONS PER EACH WEEK. IN ORDER TO MEASURE THE SLEEP QUALITY, THE PITTSBURGH SLEEP QUALITY INDEX (PSQI) WAS USED. THE DATA WERE ANALYZED BY NON-PARAMETRIC WILCOXON AND KRUSKAL-WALLIS TEST AT SIGNIFICANCE LEVEL OF P<0.05. RESULTS: OVERALL SCORE OF SLEEP QUALITY IMPROVED AFTER SIX (P=0.001) AND 12 (P=0.001) WEEKS OF YOGA EXERCISE. ALSO, SIGNIFICANT EFFECT WAS OBSERVED AFTER 6 WEEKS OF AEROBIC EXERCISE (P=0.039). HOWEVER, THE POSITIVE EFFECT WAS DIMINISHED TO UNDER SIGNIFICANT LEVELS AFTER 12 WEEKS OF AEROBIC EXERCISE (P=0.154). KRUSKAL-WALLIS TEST SHOWED SIGNIFICANT DIFFERENCES BETWEEN YOGA AND AEROBIC GROUPS AFTER 12 WEEKS OF EXERCISE (P=0.002). NO SIGNIFICANT DIFFERENCES WERE OBSERVED IN CONTROL GROUPS IN ALL SITUATION. CONCLUSIONS: IT CAN BE CONCLUDED THAT YOGA EXERCISE IS MORE EFFECTIVE IN IMPROVING THE SLEEP QUALITY IN COMPARISON WITH THE SAME COURSE OF AEROBIC EXERCISE IN WOMEN SUFFERING FROM DIABETES TYPE 2. THUS, YOGA EXERCISE CAN BE SUGGESTED TO THESE PATIENTS.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
20 1406  30 IMPACT OF YOGA ON HAEMODYNAMIC FUNCTION IN HEALTHY MEDICAL STUDENTS. OBJECTIVES: YOGA IMPROVES CARDIOVASCULAR HEALTH IN BOTH HEALTHY INDIVIDUALS AND THOSE WITH DIAGNOSED HEART DISEASE. THIS STUDY COMPARES CHANGES IN SOME CARDIOVASCULAR PARAMETERS BEFORE AND AFTER THE PRACTICE OF YOGA IN HEALTHY MEDICAL STUDENTS. METHODS: SIXTY-FOUR HEALTHY MEDICAL STUDENTS (57 FEMALES AND 7 MALES), MEAN AGE 21.3 +/- 2.6 YEARS, ATTENDING A SPECIAL STUDY MODULE 'ROLE OF DHYANA YOGA IN STRESS MANAGEMENT', PARTICIPATED IN THIS STUDY. SYSTOLIC (SYS) AND DIASTOLIC (DIA) BLOOD PRESSURE, HEART RATE (HR), STROKE VOLUME (SV), CARDIAC OUTPUT (CO), TOTAL PERIPHERAL RESISTANCE (TPR), INTERBEAT INTERVAL (IBI), LEFT VENTRICULAR EJECTION TIME (LVET), ARTERIAL COMPLIANCE (CWK) AND ASCENDING AORTA IMPEDANCE (ZAO) WERE MEASURED BEFORE AND AFTER SIX WEEKS OF YOGIC EXERCISES. VARIOUS EXERCISES INCLUDED ASANAS (POSTURES), PRANAYAMA (BREATHING), AND DHYANA (MEDITATION). DATA WERE ANALYZED USING STATA FOR WINDOWS. RESULTS: TWO-TAILED PAIRED T-TEST REVEALED THAT PRACTICE OFYOGA CAUSED SIGNIFICANT INCREASES IN HR (P < 0.05), SV (P < 0.01), CO (P < 0.001) AND CWK (P < 0.01) AND DECREASES IN TPR (P < 0.001), IBI (P < 0.05) AND ZAO (P < 0.001) AFTER PRACTISING YOGA FOR 6 WEEKS AS COMPARED TO BEFORE YOGA PRACTICE. NO SIGNIFICANT DIFFERENCES WERE, HOWEVER OBSERVED IN SYS, DIA, MEAN ARTERIAL BLOOD PRESSURE (MAP) AND LVET CONCLUSIONS: PRACTICE OF YOGA EVEN FOR A SHORT PERIOD SHOWED ABILITY TO IMPROVE MOST OF THE CARDIOVASCULAR FUNCTIONS. REGULAR PRACTICE OF YOGA FOR A LONGER PERIOD MAY FURTHER IMPROVE THESE FUNCTIONS AND POSSIBLY RESULT IN IMPROVED MANAGEMENT OF THEIR DAILY STRESS.	2011
