1 1148 116 ENERGY EXPENDITURE IN VINYASA YOGA VERSUS WALKING. BACKGROUND: WHETHER THE ENERGY COST OF VINYASA YOGA MEETS THE CRITERIA FOR MODERATE-TO-VIGOROUS PHYSICAL ACTIVITY HAS NOT BEEN ESTABLISHED. PURPOSE: TO COMPARE ENERGY EXPENDITURE DURING ACUTE BOUTS OF VINYASA YOGA AND 2 WALKING PROTOCOLS. METHODS: PARTICIPANTS (20 MALES, 18 FEMALES) PERFORMED 60-MINUTE SESSIONS OF VINYASA YOGA (YOGA), TREADMILL WALKING AT A SELF-SELECTED BRISK PACE (SELF), AND TREADMILL WALKING AT A PACE THAT MATCHED THE HEART RATE OF THE YOGA SESSION (HR-MATCH). ENERGY EXPENDITURE WAS ASSESSED VIA INDIRECT CALORIMETRY. RESULTS: ENERGY EXPENDITURE WAS SIGNIFICANTLY LOWER IN YOGA COMPARED WITH HR-MATCH (DIFFERENCE = 79.5 +/- 44.3 KCAL; P < .001) AND SELF (DIFFERENCE = 51.7 +/- 62.6 KCAL; P < .001), BUT NOT IN SELF COMPARED WITH HR-MATCH (DIFFERENCE = 27.8 +/- 72.6 KCAL; P = .054). A SIMILAR PATTERN WAS OBSERVED FOR METABOLIC EQUIVALENTS (HR-MATCH = 4.7 +/- 0.8, SELF = 4.4 +/- 0.7, YOGA = 3.6 +/- 0.6; P < .001). ANALYSES USING ONLY THE INITIAL 45 MINUTES FROM EACH OF THE SESSIONS, WHICH EXCLUDED THE RESTORATIVE COMPONENT OF YOGA, SHOWED ENERGY EXPENDITURE WAS SIGNIFICANTLY LOWER IN YOGA COMPARED WITH HR-MATCH (DIFFERENCE = 68.0 +/- 40.1 KCAL; P < .001) BUT NOT COMPARED WITH SELF (DIFFERENCE = 15.1 +/- 48.7 KCAL; P = .189). CONCLUSIONS: YOGA MEETS THE CRITERIA FOR MODERATE-INTENSITY PHYSICAL ACTIVITY. THUS, YOGA MAY BE A VIABLE FORM OF PHYSICAL ACTIVITY TO ACHIEVE PUBLIC HEALTH GUIDELINES AND TO ELICIT HEALTH BENEFITS. 2017
2 1398 24 IMPACT OF YOGA INTERVENTION ON MENOPAUSAL SYMPTOMS-SPECIFIC QUALITY OF LIFE AND CHANGES IN HORMONAL LEVEL AMONG MENOPAUSAL WOMEN. AIM: THE MENOPAUSE TRANSITION IS EXPERIENCED BY WOMEN OFTEN INVOLVES TROUBLESOME SYMPTOMS DUE TO CHANGES IN THE LEVEL OF REPRODUCTIVE HORMONES. NON-HORMONAL THERAPIES ARE MORE COMMONLY ACCEPTED BY WOMEN THAN HORMONAL THERAPY FOR COPING WITH THE CLIMACTERIC SYMPTOMS. THE AIM OF THE STUDY WAS TO EVALUATE THE EFFECTS OF YOGA PRACTICE ON MENOPAUSAL SYMPTOMS, SPECIFIC QUALITY OF LIFE, AND CHANGES IN HORMONAL LEVELS AMONG MENOPAUSAL WOMEN. METHOD: A SINGLE-BLINDED RANDOMIZED CONTROL TRIAL WAS CONDUCTED AMONG 80 PARTICIPANTS AGED 40 OF 50 YEARS AND WAS RANDOMLY DIVIDED INTO TWO STUDY ARMS, THAT IS, SUDARSHAN KRIYA YOGA (SKY) AND BRISK WALKING INTERVENTION, TO FIND THE EFFECT ON THE HORMONAL CHANGES AND MENOPAUSAL QUALITY OF LIFE (MEASURED BY MENQOL TOOL). THE SIGNIFICANT IMPROVEMENTS IN THE OUTCOME MEASURES WERE MEASURED BY USING REPEATED MEASURES ANALYSIS OF VARIANCE AND MCNEMAR'S TEST. RESULTS: SIGNIFICANT IMPROVEMENTS IN THE MENOPAUSAL-SPECIFIC QUALITY OF LIFE WERE OBSERVED IN THE DOMAIN OF VASOMOTOR, PSYCHOSOCIAL, AND PHYSICAL SYMPTOMS (P < 0.05). THE ANTIOXIDANT ENZYMES (SUPEROXIDE DISMUTASE AND GLUTATHIONE PEROXIDASE (GPX) WERE SIGNIFICANTLY ELEVATED AFTER 1 YEAR OF REGULAR PRACTICE OF SKY COMPARED TO WALKING INTERVENTION (P < 0.05). IN CONTRAST, NO SIGNIFICANT IMPROVEMENT WAS OBSERVED IN FOLLICLE-STIMULATING HORMONE AND DEHYDROEPIANDROSTERONE SULFATE LEVELS. THE WOMEN REPORTED NO ADVERSE EVENTS AFTER SKY PRACTICE OR BRISK WALKING. CONCLUSION: THE STUDY CONCLUDED THAT 1 YEAR OF SKY PRACTICE COULD BE ONE OF THE PREFERRED NON-HORMONAL, LIFESTYLE-MODIFYING REGIMENS FOR IMPROVING THE OVERALL QUALITY OF LIFE IN MENOPAUSAL WOMEN. 2021
3 772 28 EFFECT OF YOGA AND EXERCISE ON GLYCEMIC CONTROL AND PSYCHOSOCIAL PARAMETERS IN TYPE 2 DIABETES MELLITUS: A RANDOMIZED CONTROLLED STUDY. CONTEXT BACKGROUND: TYPE 2 DIABETES HAS BEEN STRONGLY ASSOCIATED WITH PSYCHOSOCIAL FACTORS SUCH AS STRESS, ANXIETY, DEPRESSION, AND QUALITY OF LIFE (QOL). THERE IS NOT MUCH EVIDENCE WHETHER YOGA CAN IMPROVE THESE FACTORS AND MOTIVATE INDIVIDUALS TO ENGAGE IN ACTIVE LIFESTYLE. AIMS: THIS STUDY AIMS TO EVALUATE THE EFFECT OF YOGA AND EXERCISE OVER GLYCEMIC CONTROL, ANXIETY, DEPRESSION, EXERCISE SELF-EFFICACY (ESE), AND QOL AFTER 3-MONTH PROGRAM. METHODS: TWO HUNDRED AND TWENTY-SEVEN INDIVIDUALS WERE RANDOMLY ALLOCATED TO YOGA GROUP (YG) AND EXERCISE GROUP. YG PRACTICED YOGA FOR 2 WEEKS UNDER SUPERVISION AND THEN CARRIED OUT PRACTICE AT HOME FOR 3 MONTHS. THE EXERCISE GROUP PRACTICED 30 MIN OF BRISK WALKING FOR 5 DAYS A WEEK. RESULTS: ON COMPARISON AMONG THE GROUPS, IN YG, THERE WAS A MEAN CHANGE OF 0.47 IN GLYCATED HEMOGLOBIN WHICH WAS GREATER THAN MEAN REDUCTION OF 0.28 IN THE EXERCISE GROUP WITH P < 0.05. STATE ANXIETY REDUCED BY 7.8 AND TRAIT ANXIETY REDUCED BY 4.4 IN YG (P < 0.05) IN 3 MONTHS AS COMPARED TO NONSIGNIFICANT REDUCTIONS OF 3 AND 1 IN MEAN OF STATE AND TRAIT ANXIETY SCORES IN THE EXERCISE GROUP (P > 0.05). THERE WAS A STATISTICALLY SIGNIFICANT REDUCTION IN DEPRESSION SCORE IN BOTH THE GROUPS, 8.6 IN YOGA AND 4.0 IN EXERCISE, WHICH WAS GREATER IN YG. ESE IMPROVED BY 19.2 IN YG (P < 0.05), WHEREAS IT IMPROVED ONLY 2.2 IN THE EXERCISE GROUP (P > 0.05). QOL IMPROVED BY 23.7 IN YG AND 3.0 IN THE EXERCISE GROUP WHICH WAS NONSIGNIFICANT IN THE EXERCISE GROUP AS COMPARED TO YG. CONCLUSIONS: YOGA IS SUPERIOR TO EXERCISE ALONE AS A LIFESTYLE MODIFICATION PROGRAM IN IMPROVING GLYCEMIC CONTROL, ANXIETY, DEPRESSION, AND QOL AS WELL AS ESE. 2020
4 265 28 ACUTE EFFECTS OF AEROBIC EXERCISE AND HATHA YOGA ON CRAVING TO SMOKE. INTRODUCTION: RECENT STUDIES HAVE EXAMINED THE EFFECTS OF PHYSICAL ACTIVITY ON CRAVING TO SMOKE AND SMOKING WITHDRAWAL. THE CURRENT STUDY WAS DESIGNED TO COMPARE AND CONTRAST THE EFFECTS OF 2 DIFFERENT FORMS OF PHYSICAL ACTIVITY ON GENERAL AND CUE-ELICITED CRAVING TO SMOKE. METHODS: FOLLOWING 1-HR NICOTINE ABSTINENCE, 76 DAILY SMOKERS WERE RANDOMLY ASSIGNED TO ENGAGE IN A 30-MIN BOUT OF CARDIOVASCULAR EXERCISE (CE; BRISK WALK ON A TREADMILL), HATHA YOGA (HY), OR A NONACTIVITY CONTROL CONDITION. PARTICIPANTS COMPLETED MEASURES OF CRAVING AND MOOD, AND A SMOKING CUE REACTIVITY ASSESSMENT, BEFORE, IMMEDIATELY FOLLOWING, AND APPROXIMATELY 20 MIN AFTER THE PHYSICAL ACTIVITY OR CONTROL CONDITIONS. RESULTS: COMPARED WITH THE CONTROL CONDITION, PARTICIPANTS IN EACH OF THE PHYSICAL ACTIVITY GROUPS REPORTED A DECREASE IN CRAVING TO SMOKE, AN INCREASE IN POSITIVE AFFECT, AND A DECREASE IN NEGATIVE AFFECT. IN ADDITION, CRAVING IN RESPONSE TO SMOKING CUES WAS SPECIFICALLY REDUCED AMONG THOSE WHO ENGAGED IN CE, WHEREAS THOSE WHO ENGAGED IN HY REPORTED A GENERAL DECREASE IN CRAVINGS. CONCLUSIONS: THIS STUDY PROVIDES FURTHER SUPPORT FOR THE USE OF EXERCISE BOUTS FOR ATTENUATING CIGARETTE CRAVINGS DURING TEMPORARY NICOTINE ABSTINENCE. RESULTS ALSO SUGGEST THAT CE CAN ATTENUATE CRAVINGS IN RESPONSE TO SMOKING CUES. THERE ARE SEVERAL AREAS FOR FURTHER RESEARCH THAT MAY IMPROVE INTEGRATION OF EXERCISE WITHIN SMOKING CESSATION TREATMENT. 2011
5 1426 21 IMPROVEMENT OF GLUTATHIONE AND TOTAL ANTIOXIDANT STATUS WITH YOGA. OBJECTIVE: SEVERAL STUDIES SUGGEST THAT YOGA CAN DECREASE OXIDATIVE STRESS. HOWEVER REPORTS ARE SCANTY REGARDING WHETHER YOGA TRAINING CAN IMPROVE THE GLUTATHIONE LEVEL OF INDIVIDUAL. THIS STUDY IS DESIGNED TO APPRAISE THE ROLE OF YOGA IN MAINTAINING GLUTATHIONE (REDUCED AND OXIDIZED) LEVELS AND ANTIOXIDANT STATUS. STUDY DESIGN: THIS STUDY WAS CONDUCTED ON HEALTHY MALE VOLUNTEERS FROM THE INDIAN NAVY, WHO WERE DIVIDED INTO TWO GROUPS--A YOGA (N = 30) GROUP AND A CONTROL (N = 21) GROUP. THE YOGA GROUP WAS TRAINED IN YOGA FOR 6 MONTHS. THE YOGA SCHEDULE CONSISTED OF PRAYERS, ASANA, PRANAYAMA, AND MEDITATION. THE CONTROL GROUP PRACTICED ROUTINE PHYSICAL TRAINING EXERCISE FOR 6 MONTHS. BLOOD SAMPLES WERE COLLECTED WHEN THE VOLUNTEERS WERE IN FASTING CONDITION BEFORE AND AFTER COMPLETION OF 6-MONTH TRAINING PERIOD. REDUCED AND OXIDIZED GLUTATHIONE, GLUTATHIONE REDUCTASE ACTIVITY AND TOTAL ANTIOXIDANT STATUS (TAS) WERE ESTIMATED. RESULTS: REDUCED GLUTATHIONE LEVEL INCREASED SIGNIFICANTLY (P < 0.05) IN THE YOGA GROUP AFTER COMPLETION OF TRAINING. GLUTATHIONE REDUCTASE ACTIVITY INCREASED SIGNIFICANTLY IN THE CONTROL GROUP (P < 0.05). TAS INCREASED SIGNIFICANTLY (P < 0.001) IN THE YOGA GROUP AND DECREASED SIGNIFICANTLY (P < 0.001) IN THE CONTROL GROUP. CONCLUSIONS: REGULAR PRACTICE OF YOGA CAN MAINTAIN OR IMPROVE ANTIOXIDANT LEVEL OF THE BODY. THE CLINICAL RELEVANCE IS THAT YOGA PRACTICE CAN BE USED TO MAINTAIN THE ANTIOXIDANT DEFENSE SYSTEM UNDER STRESSFUL CONDITIONS OF TRAINING AS OBSERVED IN THE CASE OF SOLDIERS AND ATHLETES. 2007
6 1693 32 OXYGEN CONSUMPTION DURING VINIYOGA PRACTICE IN ADULTS. CONTEXT: THE PURPOSE OF THIS STUDY WAS TO MEASURE THE OXYGEN CONSUMPTION (VO2) DURING VINIYOGA YOGA MOVEMENTS (ASANAS) AND TO COMPARE VO2 WALKING AMONG ADULTS. METHODS: YOGA PRACTITIONERS (N = 10) WERE RECRUITED TO MEASURE VO2 WHILE AT REST (30 MIN), PRACTICING YOGA (16 MOVEMENTS WITH DIFFERENT VARIATIONS), AND TREADMILL WALKING AT 2 MPH (10 MIN) AND 3 MPH (10 MIN). VO2 WAS MEASURED USING A WHOLE-ROOM INDIRECT CALORIMETRY. EACH YOGA MOVEMENT WAS CATEGORIZED BY BODY ORIENTATION AS STANDING, LYING, AND SITTING. THE DIFFERENCES IN VO2 BETWEEN YOGA AND WALKING WERE EXAMINED USING PEARSON'S CORRELATIONS. DIFFERENCES IN VO2 BETWEEN POSES (STANDING, SITTING, AND LYING) WERE EXAMINED USING LINEAR REGRESSION MODELS. VO2. RESULTS: MEAN YOGA-VO2 FOR THE ENTIRE YOGA SESSION WAS 3.7 (STANDARD DEVIATION [SD] 0.43, RANGE: 4.4-8.9) ML/KG/MIN. YOGA-VO2 VARIED BY BODY ORIENTATION: STANDING = 7.5 (SD = 1.5) ML/KG/MIN, LYING = 5.3 (SD = 1.0) ML/KG/MIN, AND SITTING = 5.4 (SD = 1.1) ML/KG/MIN. AFTER ADJUSTING FOR BODY MASS, FREQUENCY OF YOGA PRACTICE, AND RESTING ENERGY EXPENDITURE, FEMALE GENDER WAS NEGATIVELY ASSOCIATED WITH MEAN YOGA VO2 FOR STANDING (B = -112.19, P < 0.05), LYING (B = -141.87, P < 0.05), AND SITTING (B = -129.96, P < 0.05). MEAN VO2 FOR WALKING 2 MPH WAS COMPARABLE WITH SITTING (R = 0.836, P < 0.05) AND LYING (R = 0.735, P < 0.05) WHEREAS WALKING AT 3 MPH WAS COMPARABLE WITH STANDING (R = 0.718, P < 0.05) AND SITTING (R = 0.760, P < 0.05). CONCLUSION: WE CONCLUDE THAT VO2 DURING YOGA PRACTICE IS COMPARABLE TO VO2 DURING SLOW TREADMILL WALKING AND MAY VARY BASED ON GENDER AND BODY ORIENTATION. 2018
7 630 26 DIFFERENCES IN ENERGY EXPENDITURE DURING HIGH-SPEED VERSUS STANDARD-SPEED YOGA: A RANDOMIZED SEQUENCE CROSSOVER TRIAL. OBJECTIVES: TO COMPARE ENERGY EXPENDITURE AND VOLUME OF OXYGEN CONSUMPTION AND CARBON DIOXIDE PRODUCTION DURING A HIGH-SPEED YOGA AND A STANDARD-SPEED YOGA PROGRAM. DESIGN: RANDOMIZED REPEATED MEASURES CONTROLLED TRIAL. SETTING: A LABORATORY OF NEUROMUSCULAR RESEARCH AND ACTIVE AGING. INTERVENTIONS: SUN-SALUTATION B WAS PERFORMED, FOR EIGHT MINUTES, AT A HIGH SPEED VERSUS AND A STANDARD-SPEED SEPARATELY WHILE OXYGEN CONSUMPTION WAS RECORDED. CALORIC EXPENDITURE WAS CALCULATED USING VOLUME OF OXYGEN CONSUMPTION AND CARBON DIOXIDE PRODUCTION. MAIN OUTCOME MEASURES: DIFFERENCE IN ENERGY EXPENDITURE (KCAL) OF HSY AND SSY. RESULTS: SIGNIFICANT DIFFERENCES WERE OBSERVED IN ENERGY EXPENDITURE BETWEEN YOGA SPEEDS WITH HIGH-SPEED YOGA PRODUCING SIGNIFICANTLY HIGHER ENERGY EXPENDITURE THAN STANDARD-SPEED YOGA (MD=18.55, SE=1.86, P<0.01). SIGNIFICANT DIFFERENCES WERE ALSO SEEN BETWEEN HIGH-SPEED AND STANDARD-SPEED YOGA FOR VOLUME OF OXYGEN CONSUMED AND CARBON DIOXIDE PRODUCED. CONCLUSIONS: HIGH-SPEED YOGA RESULTS IN A SIGNIFICANTLY GREATER CALORIC EXPENDITURE THAN STANDARD-SPEED YOGA. HIGH-SPEED YOGA MAY BE AN EFFECTIVE ALTERNATIVE PROGRAM FOR THOSE TARGETING CARDIOMETABOLIC MARKERS. 2016
8 1602 29 MENOPAUSAL QUALITY OF LIFE: RCT OF YOGA, EXERCISE, AND OMEGA-3 SUPPLEMENTS. OBJECTIVE: THE PURPOSE OF THIS STUDY WAS TO DETERMINE THE EFFICACY OF 3 NONHORMONAL THERAPIES FOR THE IMPROVEMENT OF MENOPAUSE-RELATED QUALITY OF LIFE IN WOMEN WITH VASOMOTOR SYMPTOMS. STUDY DESIGN: WE CONDUCTED A 12-WEEK 3 X 2 RANDOMIZED, CONTROLLED, FACTORIAL DESIGN TRIAL. PERI- AND POSTMENOPAUSAL WOMEN, 40-62 YEARS OLD, WERE ASSIGNED RANDOMLY TO YOGA (N = 107), EXERCISE (N = 106), OR USUAL ACTIVITY (N = 142) AND ALSO ASSIGNED RANDOMLY TO A DOUBLE-BLIND COMPARISON OF OMEGA-3 (N = 177) OR PLACEBO (N = 178) CAPSULES. WE PERFORMED THE FOLLOWING INTERVENTIONS: (1) WEEKLY 90-MINUTE YOGA CLASSES WITH DAILY AT-HOME PRACTICE, (2) INDIVIDUALIZED FACILITY-BASED AEROBIC EXERCISE TRAINING 3 TIMES/WEEK, AND (3) 0.615 G OMEGA-3 SUPPLEMENT, 3 TIMES/DAY. THE OUTCOMES WERE ASSESSED WITH THE FOLLOWING SCORES: MENOPAUSAL QUALITY OF LIFE QUESTIONNAIRE (MENQOL) TOTAL AND DOMAIN (VASOMOTOR SYMPTOMS, PSYCHOSOCIAL, PHYSICAL AND SEXUAL). RESULTS: AMONG 355 RANDOMLY ASSIGNED WOMEN WHO AVERAGE AGE WAS 54.7 YEARS, 338 WOMEN (95%) COMPLETED 12-WEEK ASSESSMENTS. MEAN BASELINE VASOMOTOR SYMPTOMS FREQUENCY WAS 7.6/DAY, AND THE MEAN BASELINE TOTAL MENQOL SCORE WAS 3.8 (RANGE, 1-8 FROM BETTER TO WORSE) WITH NO BETWEEN-GROUP DIFFERENCES. FOR YOGA COMPARED TO USUAL ACTIVITY, BASELINE TO 12-WEEK IMPROVEMENTS WERE SEEN FOR MENQOL TOTAL -0.3 (95% CONFIDENCE INTERVAL, -0.6 TO 0; P = .02), VASOMOTOR SYMPTOM DOMAIN (P = .02), AND SEXUALITY DOMAIN (P = .03) SCORES. FOR WOMEN WHO UNDERWENT EXERCISE AND OMEGA-3 THERAPY COMPARED WITH CONTROL SUBJECTS, IMPROVEMENTS IN BASELINE TO 12-WEEK TOTAL MENQOL SCORES WERE NOT OBSERVED. EXERCISE SHOWED BENEFIT IN THE MENQOL PHYSICAL DOMAIN SCORE AT 12 WEEKS (P = .02). CONCLUSION: ALL WOMEN BECOME MENOPAUSAL, AND MANY OF THEM SEEK MEDICAL ADVICE ON WAYS TO IMPROVE QUALITY OF LIFE; LITTLE EVIDENCE-BASED INFORMATION EXISTS. WE FOUND THAT, AMONG HEALTHY SEDENTARY MENOPAUSAL WOMEN, YOGA APPEARS TO IMPROVE MENOPAUSAL QUALITY OF LIFE; THE CLINICAL SIGNIFICANCE OF OUR FINDING IS UNCERTAIN BECAUSE OF THE MODEST EFFECT. 2014
9 2823 26 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 1968 23 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
11 986 20 EFFECTS OF HATHA YOGA EXERCISE ON PLASMA MALONDIALDEHYDE CONCENTRATION AND SUPEROXIDE DISMUTASE ACTIVITY IN FEMALE PATIENTS WITH SHOULDER PAIN. [PURPOSE] THE PURPOSE OF THIS STUDY WAS TO ANALYZE THE EFFECTS OF HATHA YOGA EXERCISE ON PLASMA MALONDIALDEHYDE (MDA) CONCENTRATION AND SUPEROXIDE DISMUTASE (SOD) ACTIVITY IN FEMALE PATIENTS WITH SHOULDER PAIN. [SUBJECTS] SUBJECTS COMPRISED 20 FEMALE PATIENTS WITH SHOULDER PAIN. [METHODS] SUBJECTS WERE DIVIDED INTO 2 GROUPS: A HATHA YOGA EXERCISE GROUP (N = 10) AND A CONTROL GROUP THAT PERFORMED NO EXERCISE (N = 10). THE SUBJECTS' BODY COMPOSITION, PLASMA MALONDIALDEHYDE CONCENTRATIONS, AND SUPEROXIDE DISMUTASE ACTIVITIES WERE MEASURED BEFORE AND AFTER A 16-WEEK HATHA YOGA EXERCISE PROGRAM. [RESULTS] AFTER THE 16-WEEK HATHA YOGA EXERCISE PROGRAM, THE EXERCISE GROUP HAD SIGNIFICANTLY LOWER PLASMA MDA CONCENTRATIONS THAN THE CONTROL GROUP. IN ADDITION, THE EXERCISE GROUP HAD SIGNIFICANTLY HIGHER PLASMA SOD ACTIVITY THAN THE CONTROL GROUP. [CONCLUSIONS] HATHA YOGA EXERCISE IMPROVES FLEXIBILITY, MUSCLE TONE AND STRENGTH, BALANCE, AND JOINT FUNCTION. OUR FINDINGS INDICATE THAT REGULAR AND CONTINUOUS YOGA EXERCISE EFFECTIVELY IMPROVED BODY COMPOSITION, DECREASE PLASMA MDA CONCENTRATION, AND INCREASE PLASMA SOD ACTIVITY IN FEMALE PATIENTS WITH SHOULDER PAIN. 2015
12 1147 43 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 (VO2PEAK) AND MAXIMUM HR HAD BEEN ESTIMATED EARLIER AFTER A MAXIMAL TREADMILL TEST. VO2 DURING VINYASA YOGA SESSIONS WAS ESTIMATED FROM INDIVIDUAL REGRESSION EQUATIONS USING THE RELATIONSHIP OF VO2 AND HR VALUES DERIVED FROM VO2PEAK 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
13 692 18 EFFECT OF COMMUNITY-BASED YOGA INTERVENTION ON OXIDATIVE STRESS AND GLYCEMIC PARAMETERS IN PREDIABETES: A RANDOMIZED CONTROLLED TRIAL. OBJECTIVES: TO STUDY THE EFFECTIVENESS OF YOGA INTERVENTION ON OXIDATIVE STRESS, GLYCEMIC STATUS, BLOOD PRESSURE AND ANTHROPOMETRY IN PREDIABETES. DESIGN: RANDOMIZED-CONTROLLED TRIAL. PARTICIPANTS: TWENTY NINE PREDIABETES SUBJECTS AGED 30-75 YEARS. SETTING: YOGA WAS CONDUCTED AT 4 DIFFERENT COMMUNITY DIABETES CLINICS IN MANGALORE, INDIA. INTERVENTIONS: PARTICIPANTS WERE RANDOMIZED TO EITHER 3-MONTH YOGA OR WAIT-LIST CONTROL GROUPS. MAIN OUTCOME MEASURES: MALONDIALDEHYDE, GLUTATHIONE, VITAMIN C, VITAMIN E, SUPEROXIDE DISMUTASE, PLASMA GLUCOSE, GLYCATED HAEMOGLOBIN, BMI, WAIST CIRCUMFERENCE, WAIST-TO-HIP RATIO AND BLOOD PRESSURE. RESULTS: YOGA INTERVENTION RESULTED IN A SIGNIFICANT DECLINE IN MALONDIALDEHYDE (P<0.001), RELATIVE TO THE CONTROL GROUP. IN COMPARISON WITH THE CONTROL, THERE WAS A SIGNIFICANT IMPROVEMENT IN BMI, WAIST CIRCUMFERENCE, SYSTOLIC BLOOD PRESSURE AND FASTING GLUCOSE LEVELS AT FOLLOW-UP. NO SIGNIFICANT IMPROVEMENT IN GLYCATED HAEMOGLOBIN, WAIST-TO-HIP RATIO OR ANY OF THE ANTIOXIDANTS WAS OBSERVED. CONCLUSIONS: YOGA INTERVENTION MAY BE HELPFUL IN CONTROL OF OXIDATIVE STRESS IN PREDIABETES SUBJECTS. YOGA CAN ALSO BE BENEFICIAL IN REDUCTION IN BMI, WAIST CIRCUMFERENCE, SYSTOLIC BLOOD PRESSURE AND FASTING GLUCOSE. EFFECT OF YOGA ON ANTIOXIDANT PARAMETERS WAS NOT EVIDENT IN THIS STUDY. THE FINDINGS OF THIS STUDY NEED TO BE CONFIRMED IN LARGER TRIALS INVOLVING ACTIVE CONTROL GROUPS. 2013
14 389 27 BENEFITS OF YOGA FOR AFRICAN AMERICAN HEART FAILURE PATIENTS. BACKGROUND: THE NUMBER OF AFRICAN AMERICAN (AA) PATIENTS LIVING WITH HEART FAILURE (HF) HAS BEEN INCREASING, ESPECIALLY AMONG THE ECONOMICALLY DISADVANTAGED. YOGA THERAPY HAS BEEN FOUND TO IMPROVE PHYSICAL AND PSYCHOLOGICAL PARAMETERS AMONG HEALTHY INDIVIDUALS, BUT ITS EFFECT IN PATIENTS WITH HF REMAINS UNKNOWN. THE PURPOSE OF THIS STUDY WAS TO EXAMINE THE EFFECTS OF YOGA THERAPY ON CARDIOVASCULAR ENDURANCE (VO2PEAK), FLEXIBILITY, QUALITY OF LIFE (QOL), AND INFLAMMATORY MARKERS ON MEDICALLY STABLE HF PATIENTS. METHODS: FORTY PATIENTS (38 AA, 1 ASIAN, AND 1 CAUCASIAN) WITH SYSTOLIC OR DIASTOLIC HF WERE RANDOMIZED TO THE YOGA GROUP (YG, N = 21) OR THE CONTROL GROUP (CG, N = 19). ALL PATIENTS WERE ASKED TO FOLLOW A HOME WALK PROGRAM. PREMEASUREMENT AND POSTMEASUREMENT INCLUDED A TREADMILL STRESS TEST TO PEAK EXERTION, FLEXIBILITY, INTERLEUKIN-6 (IL-6), C-REACTIVE PROTEIN (CRP), AND EXTRACELLULAR SUPEROXIDE DISMUTASE (EC-SOD). QOL WAS ASSESSED BY THE MINNESOTA LIVING WITH HEART FAILURE QUESTIONNAIRE (MLWHFQ). RESULTS: THE STATISTICAL ANALYSES (ASSESSED BY ANOVA AND T-TESTS) WERE SIGNIFICANT FOR FAVORABLE CHANGES IN THE YG, COMPARED WITH THOSE IN THE CG, FOR FLEXIBILITY (P = 0.012), TREADMILL TIME (P = 0.002), VO2PEAK (P = 0.003), AND THE BIOMARKERS (IL-6, P = 0.004; CRP, P = 0.016; AND EC-SOD, P = 0.012). WITHIN THE YG, PRETEST TO POSTTEST SCORES FOR THE TOTAL (P = 0.02) AND PHYSICAL SUBSCALES (P < 0.001) OF THE MLWHFQ WERE IMPROVED. CONCLUSIONS: YOGA THERAPY OFFERED ADDITIONAL BENEFITS TO THE STANDARD MEDICAL CARE OF PREDOMINANTLY AA HF PATIENTS BY IMPROVING CARDIOVASCULAR ENDURANCE, QOL, INFLAMMATORY MARKERS, AND FLEXIBILITY. 2010
15 50 23 A COMPARATIVE CONTROLLED TRIAL COMPARING THE EFFECTS OF YOGA AND WALKING FOR OVERWEIGHT AND OBESE ADULTS. BACKGROUND: WALKING AND YOGA HAVE BEEN INDEPENDENTLY EVALUATED FOR WEIGHT CONTROL; HOWEVER, THERE ARE VERY FEW STUDIES COMPARING THE 2 WITH RANDOMIZATION. MATERIAL AND METHODS: THE PRESENT STUDY COMPARED THE EFFECTS OF 90 MINUTES/DAY FOR 15 DAYS OF SUPERVISED YOGA OR SUPERVISED WALKING ON: (I) RELATED BIOCHEMISTRY, (II) ANTHROPOMETRIC VARIABLES, (III) BODY COMPOSITION, (IV) POSTURAL STABILITY, AND (V) BILATERAL HAND GRIP STRENGTH IN OVERWEIGHT AND OBESE PERSONS. SIXTY-EIGHT PARTICIPANTS, OF WHOM 5 WERE OVERWEIGHT (BMI >/=25 KG/M2) AND 63 WERE OBESE (BMI >/=30 KG/M2; GROUP MEAN AGE +/-S.D., 36.4+/-11.2 YEARS; 35 FEMALES), WERE RANDOMIZED AS 2 GROUPS - (I) A YOGA GROUP AND (II) A WALKING GROUP - GIVEN THE SAME DIET. RESULTS: ALL DIFFERENCES WERE PRE-POST CHANGES WITHIN EACH GROUP. BOTH GROUPS SHOWED A SIGNIFICANT (P<0.05; REPEATED MEASURES ANOVA, POST-HOC ANALYSES) DECREASE IN: BMI, WAIST CIRCUMFERENCE, HIP CIRCUMFERENCE, LEAN MASS, BODY WATER, AND TOTAL CHOLESTEROL. THE YOGA GROUP INCREASED SERUM LEPTIN (P<0.01) AND DECREASED LDL CHOLESTEROL (P<0.05). THE WALKING GROUP DECREASED SERUM ADIPONECTIN (P<0.05) AND TRIGLYCERIDES (P<0.05). CONCLUSIONS: BOTH YOGA AND WALKING IMPROVED ANTHROPOMETRIC VARIABLES AND SERUM LIPID PROFILE IN OVERWEIGHT AND OBESE PERSONS. THE POSSIBLE IMPLICATIONS ARE DISCUSSED. 2014
16 771 28 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
17 859 26 EFFECT OF YOGA PRACTICE ON LEVELS OF INFLAMMATORY MARKERS AFTER MODERATE AND STRENUOUS EXERCISE. BACKGROUND AND OBJECTIVES: TO EVALUATE THE EFFECT OF YOGA PRACTICE AND EXERCISE CHALLENGE ON TUMOUR NECROSIS FACTOR ALPHA (TNF-ALPHA), INTERLEUKIN-6 (IL-6) LEVELS AND LIPID PROFILE. MATERIALS AND METHODS: TWO HUNDRED AND EIGHTEEN SUBJECTS PARTICIPATED IN THE STUDY. ONE HUNDRED AND NINE VOLUNTEERS (51 MALES AND 58 FEMALES) IN THE AGE GROUP OF 20 TO 60 YEARS, WHO PRACTICED YOGA REGULARLY FOR OVER FIVE YEARS FOR A PERIOD OF ONE HOUR DAILY, PERFORMED A BOUT OF MODERATE EXERCISE AND A BOUT OF STRENUOUS EXERCISE AS PER STANDARDIZED SHUTTLE WALK TEST PROTOCOL. ANTHROPOMETRICALLY MATCHED, AGE MATCHED AND GENDER MATCHED SUBJECTS, WHO DID NOT PRACTICE YOGA (NON-YOGA GROUP) WERE CHOSEN AS CONTROLS (NON-YOGA, N=109). THE NON-YOGA GROUP ALSO PERFORMED SIMILAR EXERCISES. THE BLOOD SAMPLES OF BOTH THE GROUPS WERE COLLECTED BEFORE AND AFTER THE EXERCISES. TNF-ALPHA AND IL-6 WAS ANALYSED BEFORE AND AFTER THE EXERCISE BY SANDWICH ELISA (ENZYME LINKED IMMUNOSORBENT ASSAY). RESULTS: RESTING PLASMA TNF-ALPHA CONCENTRATION WAS SIGNIFICANTLY HIGHER IN NON-YOGA GROUP WHEN COMPARED TO YOGA GROUP (P<0.05). THERE WAS AN INCREASE IN TNF-ALPHA LEVELS IN BOTH THE GROUPS IN RESPONSE TO STRENUOUS EXERCISE. THERE WAS NO GENDER DIFFERENCE IN TNF-ALPHA AND IL-6 LEVELS BEFORE AND AFTER EXERCISE IN YOGA AND NON-YOGA GROUPS. CONCLUSION: REGULAR PRACTICE OF YOGA LOWERS BASAL TNF-ALPHA AND IL-6 LEVELS. IT ALSO REDUCES THE EXTENT OF INCREASE OF TNF-ALPHA AND IL-6 TO A PHYSICAL CHALLENGE OF MODERATE EXERCISE AND STRENUOUS EXERCISE. THERE IS NO SIGNIFICANT GENDER DIFFERENCE IN THE TNF-ALPHA AND IL-6 LEVELS. REGULAR PRACTICE OF YOGA CAN PROTECT THE INDIVIDUAL AGAINST INFLAMMATORY DISEASES BY FAVOURABLY ALTERING PRO-INFLAMMATORY CYTOKINE LEVELS. 2015
18 1102 26 EFFECTS OF YOGA TRAINING ON BODY COMPOSITION AND OXIDANT-ANTIOXIDANT STATUS AMONG HEALTHY MALE. BACKGROUND: THE STRESSFUL CONDITION MAY CAUSE OXIDATIVE STRESS, WHICH IS RESPONSIBLE FOR VARIOUS DISEASES. AIMS: THE PRESENT STUDY WAS DESIGNED TO FIND OUT WHETHER YOGA HAS IMPACT ON THE REDUCTION OF OXIDATIVE STRESS. METHODS: FOR THE PRESENT STUDY, 95 (N = 95) HEALTHY MALE VOLUNTEERS WITHIN THE AGE GROUP OF 18-24 YEARS WERE INCLUDED, 35 (N = 35) VOLUNTEERS WERE EXCLUDED. THE REMAINING 60 (N = 60) VOLUNTEERS WERE RANDOMLY DIVIDED INTO TWO GROUPS: (A) YOGA GROUP (N = 30) AND (B) CONTROL GROUP (N = 30). YOGA TRAINING WAS GIVEN FOR 60 MIN PER DAY, 6 DAYS PER WEEK FOR 12 WEEKS IN THE YOGA GROUP, WITH NO YOGA TRAINING IN CONTROL GROUP. ASSESSMENT OF BODY COMPOSITION AND OXIDANT-ANTIOXIDANT STATUS WERE PERFORMED IN BOTH THE GROUPS AT BASELINE, BEFORE YOGA TRAINING (0 WEEK) AND AFTER (12 WEEKS) OF THE TRAINING. RESULTS: SIGNIFICANT REDUCTION (P < 0.001) IN THE PERCENTAGE OF BODY FAT AND MALONDIALDEHYDE; SIGNIFICANT ELEVATION (P < 0.001) IN SUPEROXIDE DISMUTASE, CATALASE, REDUCED GLUTATHIONE AND ASCORBIC ACID LEVELS WERE NOTED IN THE YOGA GROUP AFTER 12 WEEKS WHEN COMPARED TO BASELINE DATA (0 WEEK). HOWEVER, THERE WAS NO SIGNIFICANT DIFFERENCE IN HEIGHT, WEIGHT, BODY MASS INDEX, BODY SURFACE AREA AND LEAN BODY MASS AMONG THE YOGA GROUP AFTER 12 WEEKS WHEN COMPARED TO BASELINE DATA. THESE CHANGES MIGHT BE DUE TO YOGA TRAINING. CONCLUSIONS: REGULAR YOGA PRACTICE REDUCES BODY FAT AND OXIDATIVE STRESS. YOGA TRAINING MAY BE HELPFUL TO REDUCE THE CHANCE OF OCCURRENCE OF VARIOUS DISEASES AND HELPS TO MAINTAIN NORMAL HEALTHY LIFESTYLE. 2018
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
20 525 19 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
