1 437 146 CARDIOVASCULAR AND METABOLIC EFFECTS OF INTENSIVE HATHA YOGA TRAINING IN MIDDLE-AGED AND OLDER WOMEN FROM NORTHERN MEXICO. BACKGROUND: HATHA YOGA (HY) CAN BE AN ALTERNATIVE TO IMPROVE PHYSICAL ACTIVITY IN MIDDLE-AGED AND OLDER WOMEN. HOWEVER, CONVENTIONAL HY (CHY) EXERCISING MAY NOT RESULT IN ENOUGH TRAINING STIMULUS TO IMPROVE CARDIOVASCULAR FITNESS. THE PURPOSE OF THIS STUDY WAS TO EVALUATE THE EFFECT OF AN INTENSIVE HY INTERVENTION (IHY) ON CARDIOVASCULAR RISK FACTORS IN MIDDLE-AGED AND OLDER WOMEN FROM NORTHERN MEXICO. MATERIALS AND METHODS: IN THIS PROSPECTIVE QUASIEXPERIMENTAL DESIGN, FOUR MIDDLE-AGED AND NINE OLDER CHY PRACTICING FEMALES (YOGINIS) WERE ENROLLED INTO AN 11-WEEK IHY PROGRAM CONSISTING OF 5 SESSIONS/WEEK FOR 90 MIN (55 SESSIONS). THE PROGRAM ADHERENCE, ASANA PERFORMANCE, AND WORK INTENSITY WERE ASSESSED ALONG THE INTERVENTION. ANTHROPOMETRIC [BODY MASS INDEX (BMI), % BODY FAT AND SIGMA SKIN FOLDS], CARDIOVASCULAR FITNESS [MAXIMAL EXPIRED AIR VOLUME (VE(MAX)), MAXIMAL O(2) CONSUMPTION (VO(2MAX)), MAXIMAL HEART RATE (HR(MAX)), SYSTOLIC (BPS) AND DIASTOLIC BLOOD PRESSURE (BPD)], BIOCHEMICAL [GLUCOSE, TRIACYLGLYCEROLS (TAG), TOTAL CHOLESTEROL (TC), HIGH-DENSITY LIPOPROTEIN CHOLESTEROL (HDL-C), AND LOW-DENSITY LIPOPROTEIN CHOLESTEROL (LDL-C)], AND DIETARY PARAMETERS WERE EVALUATED BEFORE AND AFTER IHY. RESULTS: DAILY CALORIC INTAKE (~1,916 KCAL/DAY), PROGRAM ADHERENCE (~85%), AND EXERCISING SKILLS (ASANA PERFORMANCE) WERE SIMILAR IN BOTH MIDDLE-AGED AND OLDER WOMEN. THE IHY PROGRAM DID NOT MODIFY ANY ANTHROPOMETRIC MEASUREMENTS. HOWEVER, IT INCREASED VO(2MAX) AND VE(MAX) AND HDL-C WHILE TAG AND LDL-C REMAINED STABLE IN BOTH MIDDLE-AGED AND OLDER GROUPS (P < 0.01). CONCLUSIONS: THE PROPOSED IHY PROGRAM IMPROVES DIFFERENT CARDIOVASCULAR RISK FACTORS (NAMELY VO(2MAX) AND HDL-C) IN MIDDLE-AGED AND OLDER WOMEN. 2009
2 1653 22 MUSCLE POWER, DEXTERITY SKILL AND VISUAL PERCEPTION IN COMMUNITY HOME GIRLS TRAINED IN YOGA OR SPORTS AND IN REGULAR SCHOOL GIRLS. THE PRESENT STUDY WAS CONDUCTED TO COMPARE CRITICAL FLICKER FUSION FREQUENCY (CFF), DEGREE OF OPTICAL ILLUSION ("DI"), DEXTERITY SCORES, AND GRIP STRENGTH IN THREE GROUPS OF SUBJECTS, VIZ COMMUNITY HOME GIRLS WHO HAD LEARNED YOGA FOR 6 MONTHS (CHY), AGE-MATCHED COMMUNITY HOME GIRLS WHO HAD PHYSICAL ACTIVITY TRAINING FOR 6 MONTHS (CHP), AND GIRLS WHO WERE ATTENDING A REGULAR SCHOOL (SCH). THERE WERE EQUAL NUMBERS IN EACH GROUP FOR EACH OF THE 4 ASSESSMENT (RANGE 11 TO 30 SUBJECTS) AND AGE RANGE WAS 12 TO 16 YEARS OF AGE. THE CHP GROUP HAD SIGNIFICANTLY LOWER CFF AND "DI" WAS SIGNIFICANTLY HIGHER (ONE FACTOR ANOVA, T TEST FOR UNPAIRED DATA) IN THE CHP GROUP, BOTH COMPARED TO CHY AND SCH GROUPS. RIGHT HAND GRIP STRENGTH WAS ALSO SIGNIFICANTLY LESS IN THE CHP GROUP COMPARED TO SCH. THE RESULTS WERE EXPLAINED BY PREVIOUS REPORTS OF HIGH LEVELS OF ANXIETY AND AGGRESSION IN COMMUNITY-HOME GROUPS, WHICH IS KNOWN TO INFLUENCE THE FOUR PARAMETERS DESCRIBED HERE. THE BETTER PERFORMANCE OF THE CHY GROUP COMPARED TO CHP, SUGGESTED THAT YOGA PRACTICE HAS A BENEFICIAL EFFECT IN THESE SUBJECTS. 1997
3 1814 20 PROGRESSIVE INCREASE IN CRITICAL FLICKER FUSION FREQUENCY FOLLOWING YOGA TRAINING. THE CRITICAL FLICKER FUSION FREQUENCY (CFF) IS THE FREQUENCY AT WHICH A FLICKERING STIMULUS IS PERCEIVED TO BE STEADY, WITH HIGHER VALUES SUGGESTING GREATER PERCEPTUAL ACCURACY. THE CFF WAS MEASURED IN TWO AGE-MATCHED GROUPS OF HEALTHY MALE VOLUNTEERS WHOSE AGES RANGED FROM 25 TO 39 YEARS, WITH 18 SUBJECTS IN EACH GROUP. AFTER BASELINE ASSESSMENTS ONE GROUP (YOGA GROUP) RECEIVED YOGA TRAINING, WHILE THE OTHER GROUP (CONTROL GROUP) CARRIED ON WITH THEIR ROUTINE ACTIVITIES. YOGA PRACTICES INCLUDED ASANAS, PRANAYAMAS, KRIYAS, MEDITATION, DEVOTIONAL SESSIONS AND LECTURES ON THE THEORY OF YOGA. AFTER 10 DAYS NEITHER GROUP SHOWED A CHANGE IN CFF. HOWEVER, AT 20 AND AT 30 DAYS THE YOGA GROUP SHOWED SIGNIFICANT INCREASES IN CFF BY 11.1% AND 14.9%, RESPECTIVELY (TWO FACTOR ANOVA, TUKEY MULTIPLE COMPARISON TEST). THE CONTROL GROUP SHOWED NO CHANGE AT THE DAY 20 AND DAY 30 FOLLOWUP. 1997
4 828 36 EFFECT OF YOGA ON LIPID PROFILE AND C-REACTIVE PROTEIN IN WOMEN. BACKGROUND: FEW SCIENTIFIC STUDIES HAVE BEEN CONDUCTED ABOUT THE EFFECT OF YOGA ON BIOCHEMICAL VARIABLES SUCH AS TOTAL CHOLESTEROL (TC), HIGH-DENSITY LIPOPROTEIN CHOLESTEROL (HDL-C), LOW-DENSITY LIPOPROTEIN CHOLESTEROL (LDL-C), TRIGLYCERIDE (TG), AND C-REACTIVE PROTEIN (CRP) TO LAY A SCIENTIFIC FOUNDATION REGARDING BENEFITS OF YOGA, BUT ITS EFFECT IS NOT CLEARLY DETECTED YET. THIS STUDY WAS CONDUCTED TO ASSESS THE EFFECT OF YOGA ON LIPID PROFILE AND CRP IN WOMEN. METHODS: THIS RESEARCH WAS DESIGNED AS AN INTERVENTIONAL STUDY. AFTER REVIEWING INCLUSION AND EXCLUSION CRITERIA, SELECTED BIOCHEMICAL VARIABLES SUCH AS TC, HDL-C, LDL-C, TG, AND CRP WERE MEASURED FOR EACH PARTICIPANT. YOGA INSTRUCTION WAS DONE THREE TIMES A WEEK FOR 26 WEEKS BY AN EXPERIENCED YOGA INSTRUCTOR. AFTER 26 WEEKS OF YOGA INTERVENTION, THE ABOVE-MENTIONED DEPENDENT VARIABLES WERE ASSESSED. SPSS VER. 16 WAS USED FOR DATA ANALYSIS. RESULTS: AFTER A 26-WEEK FOLLOW-UP FOR PARTICIPANTS, ONLY 24 WOMEN HAD THE NECESSARY CRITERIA TO BE INCLUDED IN THE STUDY. THE MEAN TG WAS 157.33 +/- 68.416 MG/DL AND 134.33 +/- 58.80 MG/DL BEFORE AND AFTER THE INTERVENTION (P = 0.108), RESPECTIVELY. THE MEAN TC WAS 234.83 +/- 48.47 MG/DL AND 183.33 +/- 55.09 MG/DL BEFORE AND AFTER THE INTERVENTION (P = 0.014), RESPECTIVELY. THE MEAN HDL-C WAS 31.58 +/- 14.22 MG/DL AND 38.25 +/- 13.5 MG/DL BEFORE AND AFTER THE INTERVENTION (P = 0.118), RESPECTIVELY. THE MEAN LDL-C WAS 171.75 +/- 42.69 MG/DL AND 142.91 +/- 36.4 MG/DL BEFORE AND AFTER THE INTERVENTION (P = 0.030), RESPECTIVELY. THE MEAN CRP WAS 0.57 +/- 0.22 MG/L AND 0.71 +/- 0.77 MG/L BEFORE AND AFTER THE INTERVENTION (P = 0.779), RESPECTIVELY. CONCLUSIONS: THE RESULT SHOWED THAT YOGA REDUCED TC AND LDL-C SIGNIFICANTLY, BUT HAD NO SIGNIFICANT EFFECT ON TG, HDL-C, AND CRP. 2019
5 324 36 ANTHROPOMETRIC, BIOCHEMICAL AND CLINICAL PARAMETERS IN CLIMACTERIC YOGA PRACTITIONERS. OBJECTIVE: THIS STUDY AIMED TO EVALUATE ANTHROPOMETRIC, BIOCHEMICAL AND CLINICAL PARAMETERS IN CLIMACTERIC YOGA PRACTITIONERS. METHODS: THIS STUDY INVESTIGATED 108 CLIMACTERIC WOMEN. WE RECRUITED 28 WOMEN BETWEEN 40 AND 65 YEARS OLD WHO STARTED YOGA PRACTICES IN PREMENOPAUSE AND HAD ALREADY PRACTICED FOR AT LEAST 5 YEARS. AS CONTROLS, WE SELECTED 30 PHYSICAL ACTIVITY (PA) PRACTITIONERS WHO HAD PRACTICED FOR AT LEAST 5 YEARS AND 50 SEDENTARY WOMEN IN THE SAME AGE RANGE. WE CONDUCED ANTHROPOMETRIC, BIOCHEMICAL AND BLOOD PRESSURE MEASUREMENTS. RESULTS: THE YOGA GROUP HAD SIGNIFICANTLY LOWER FASTING BLOOD GLUCOSE THAN THE PA PRACTITIONERS AND SEDENTARY WOMEN. YOGA PRACTITIONERS ALSO HAD LOWER WEIGHT, BODY MASS INDEX, WAIST CIRCUMFERENCE, BODY FAT PERCENTAGE AND WAIST-TO-HEIGHT RATIO; HIGHER LEVELS OF HIGH-DENSITY LIPOPROTEIN CHOLESTEROL; LOWER LEVELS OF TRIGLYCERIDES, INSULIN, HOMEOSTASIS MODEL ASSESSMENT OF INSULIN RESISTANCE, URIC ACID, APOLIPOPROTEIN B AND HIGH-SENSITIVITY C-REACTIVE PROTEIN; AND LOWER FREQUENCY OF METABOLIC SYNDROME, LIPID ACCUMULATION PRODUCT, VISCERAL ADIPOSITY INDEX AND SYSTOLIC BLOOD PRESSURE THAN THE SEDENTARY WOMEN. CONCLUSION: YOGA PRACTITIONERS HAD LOWER GLUCOSE SERUM CONCENTRATIONS THAN THE PA PRACTITIONERS AND SEDENTARY WOMEN. OVERALL, THE YOGA GROUP ALSO HAD BETTER ANTHROPOMETRIC, BIOCHEMICAL AND CLINICAL VARIABLES THAN THE OTHER GROUPS. ALTHOUGH FURTHER INVESTIGATION IS REQUIRED, YOGA PRACTICE IN PREMENOPAUSE SEEMS TO BE BENEFICIAL FOR WOMEN WHEN THEY REACH MENOPAUSE. 2022
6 2816 36 YOGA TRAINING IMPROVES METABOLIC PARAMETERS IN OBESE BOYS. YOGA HAS BEEN KNOWN TO HAVE STIMULATORY OR INHIBITORY EFFECTS ON THE METABOLIC PARAMETERS AND TO BE UNCOMPLICATED THERAPY FOR OBESITY. THE PURPOSE OF THE PRESENT STUDY WAS TO TEST THE EFFECT OF AN 8-WEEK OF YOGA-ASANA TRAINING ON BODY COMPOSITION, LIPID PROFILE, AND INSULIN RESISTANCE (IR) IN OBESE ADOLESCENT BOYS. TWENTY VOLUNTEERS WITH BODY MASS INDEX (BMI) GREATER THAN THE 95TH PERCENTILE WERE RANDOMLY ASSIGNED TO YOGA (AGE 14.7+/-0.5 YEARS, N=10) AND CONTROL GROUPS (AGE 14.6+/-1.0 YEARS, N=10). THE YOGA GROUP PERFORMED EXERCISES THREE TIMES PER WEEK AT 40~60% OF HEART-RATE RESERVE (HRR) FOR 8 WEEKS. IR WAS DETERMINED WITH THE HOMEOSTASIS MODEL ASSESSMENT OF INSULIN RESISTANCE (HOMA-IR). AFTER YOGA TRAINING, BODY WEIGHT, BMI, FAT MASS (FM), AND BODY FAT % (BF %) WERE SIGNIFICANTLY DECREASED, AND FAT-FREE MASS AND BASAL METABOLIC RATE WERE SIGNIFICANTLY INCREASED THAN BASELINE VALUES. FM AND BF % WERE SIGNIFICANTLY IMPROVED IN THE YOGA GROUP COMPARED WITH THE CONTROL GROUP (P<0.05). TOTAL CHOLESTEROL (TC) WAS SIGNIFICANTLY DECREASED IN THE YOGA GROUP (P<0.01). HDL-CHOLESTEROL WAS DECREASED IN BOTH GROUPS (P<0.05). NO SIGNIFICANT CHANGES WERE OBSERVED BETWEEN OR WITHIN GROUPS FOR TRIGLYCERIDES, LDL-CHOLESTEROL, GLUCOSE, INSULIN, AND HOMA-IR. OUR FINDINGS SHOW THAT AN 8-WEEK OF YOGA TRAINING IMPROVES BODY COMPOSITION AND TC LEVELS IN OBESE ADOLESCENT BOYS, SUGGESTING THAT YOGA TRAINING MAY BE EFFECTIVE IN CONTROLLING SOME METABOLIC SYNDROME FACTORS IN OBESE ADOLESCENT BOYS. 2012
7 1030 40 EFFECTS OF YOGA EXERCISE ON SERUM ADIPONECTIN AND METABOLIC SYNDROME FACTORS IN OBESE POSTMENOPAUSAL WOMEN. OBJECTIVE: REGULAR AND CONTINUOUS YOGA EXERCISE IS ONE OF THE MOST IMPORTANT NONPHARMACOLOGICAL METHODS OF IMPROVING SERUM LIPID CONCENTRATIONS, ADIPOSE TISSUE, AND METABOLIC SYNDROME FACTORS. THE PURPOSE OF THIS STUDY WAS TO ANALYZE THE EFFECTS OF YOGA EXERCISE ON SERUM ADIPONECTIN AND METABOLIC SYNDROME FACTORS IN OBESE POSTMENOPAUSAL KOREAN WOMEN. METHODS: SIXTEEN HEALTHY POSTMENOPAUSAL WOMEN AGED 54.50 +/- 2.75 YEARS WITH MORE THAN 36% BODY FAT WERE RANDOMLY ASSIGNED TO EITHER A YOGA EXERCISE GROUP (N = 8) OR TO A "NO EXERCISE" CONTROL GROUP (N = 8). THE VARIABLES OF BODY COMPOSITION, VISCERAL FAT, SERUM ADIPONECTIN, AND METABOLIC SYNDROME FACTORS WERE MEASURED IN ALL THE PARTICIPANTS BEFORE AND AFTER THE 16-WEEK STUDY. RESULTS: BODY WEIGHT, PERCENTAGE OF BODY FAT, LEAN BODY MASS, BODY MASS INDEX, WAIST CIRCUMFERENCE, AND VISCERAL FAT AREA HAD SIGNIFICANTLY DECREASED. HIGH-DENSITY LIPOPROTEIN CHOLESTEROL AND ADIPONECTIN HAD SIGNIFICANTLY INCREASED, BUT TOTAL CHOLESTEROL, TRIGLYCERIDE, LOW-DENSITY LIPOPROTEIN CHOLESTEROL, BLOOD PRESSURE, INSULIN, GLUCOSE, AND HOMOEOSTASIS MODEL ASSESSMENT-INSULIN RESISTANCE HAD SIGNIFICANTLY DECREASED. SERUM ADIPONECTIN CONCENTRATIONS WERE SIGNIFICANTLY CORRELATED WITH WAIST CIRCUMFERENCE, HIGH-DENSITY LIPOPROTEIN CHOLESTEROL, DIASTOLIC BLOOD PRESSURE, AND HOMOEOSTASIS MODEL ASSESSMENT-INSULIN RESISTANCE IN THE POSTYOGA EXERCISE GROUP. CONCLUSIONS: OUR FINDINGS INDICATE THAT YOGA EXERCISE IMPROVES ADIPONECTIN LEVEL, SERUM LIPIDS, AND METABOLIC SYNDROME RISK FACTORS IN OBESE POSTMENOPAUSAL WOMEN. CONSEQUENTLY, YOGA EXERCISE WILL BE EFFECTIVE IN PREVENTING CARDIOVASCULAR DISEASE CAUSED BY OBESITY IN OBESE POSTMENOPAUSAL KOREAN WOMEN. 2012
8 913 41 EFFECTIVENESS OF LIQUID FASTING WITH YOGA AND NATUROPATHY TREATMENTS IN REDUCING METABOLIC AND CARDIOVASCULAR RISKS IN OBESITY. CONTEXT: OBESITY IS ASSOCIATED WITH CHRONIC DISEASES, INCLUDING METABOLIC SYNDROME AND CARDIOVASCULAR DISEASES (CVDS). FASTING IS COMMONLY EMPLOYED BY OBESE PEOPLE TO REDUCE THEIR WEIGHT. LIKEWISE, YOGA AND NATUROPATHY (YN) THAT INCLUDE LIQUID FASTING (LF) HAVE BEEN SHOWN TO BE BENEFICIAL IN REDUCING WEIGHT FOR PEOPLE WITH METABOLIC DISORDERS. HOWEVER, THE SAFETY OF LF DURING YN TREATMENTS AND ITS EFFECTS ON METABOLIC AND CARDIOVASCULAR RISK FACTORS HAVEN'T YET BEEN REPORTED. OBJECTIVE: THE STUDY INTENDED TO EVALUATE THE SAFETY OF LF DURING YN TREATMENTS AND ITS EFFECTS ON METABOLIC AND CARDIOVASCULAR RISK FACTORS IN PEOPLE WITH OBESITY. DESIGN: A SINGLE-GROUP, PRETEST-AND-POSTTEST DESIGN WAS ADOPTED FOR THE STUDY. SETTING: THE STUDY TOOK PLACE IN A YN HOSPITAL LOCATED IN SOUTH INDIA. PARTICIPANTS: PARTICIPANTS WERE 176 OBESE PEOPLE AGED BETWEEN 18 AND 65 YEARS. INTERVENTION: TOGETHER WITH YN TREATMENTS, ALL PARTICIPANTS UNDERWENT LF USING LIME JUICE WITH JAGGERY, ASH GUARD JUICE, VEGETABLE SOUP, BUTTERMILK, AND KOKUM JUICE FOR A PERIOD OF 5 CONSECUTIVE DAYS. OUTCOME MEASURES: ASSESSMENTS SUCH AS BODY WEIGHT, BODY MASS INDEX (BMI), FAT MASS, LIPID PROFILE, AND BLOOD PRESSURE WERE TAKEN AT BASELINE AND POSTINTERVENTION. RESULTS: PARTICIPANTS SHOWED A SIGNIFICANT REDUCTION IN BODY WEIGHT, BMI, FAT MASS, TRIGLYCERIDES (TG), TOTAL CHOLESTEROL (TC), LOW-DENSITY LIPOPROTEIN CHOLESTEROL (LDL-C), VERY-LOW-DENSITY LIPOPROTEIN CHOLESTEROL (VLDL-C), HIGH-DENSITY LIPOPROTEIN CHOLESTEROL (HDL-C), SYSTOLIC BLOOD PRESSURE (SBP), AND DIASTOLIC BLOOD PRESSURE (DBP). CONCLUSIONS: THE RESULTS SUGGEST THAT LF DURING YN TREATMENT CANBE EFFECTIVE IN REDUCING METABOLIC AND CARDIOVASCULAR RISK FACTORS IN PEOPLE WITH OBESITY. 2021
9 2252 32 THE METABOLIC COST OF HATHA YOGA. TO DETERMINE THE METABOLIC AND HEART RATE (HR) RESPONSES OF HATHA YOGA, 26 WOMEN (19-40 YEARS OLD) PERFORMED A 30-MINUTE HATHA YOGA ROUTINE OF SUPINE LYING, SITTING, AND STANDING ASANAS (I.E., POSTURES). SUBJECTS FOLLOWED IDENTICAL VIDEOTAPED SEQUENCES OF HATHA YOGA ASANAS. MEAN PHYSIOLOGICAL RESPONSES WERE COMPARED TO THE PHYSIOLOGICAL RESPONSES OF RESTING IN A CHAIR AND WALKING ON A TREADMILL AT 93.86 M.MIN(-1) [3.5 MILES PER HOUR (MPH)]. DURING THE 30-MINUTE HATHA YOGA ROUTINE, MEAN ABSOLUTE OXYGEN CONSUMPTION (VO(2)), RELATIVE VO(2), PERCENTAGE MAXIMAL OXYGEN CONSUMPTION (%VO(2)R), METABOLIC EQUIVALENTS (METS), ENERGY EXPENDITURE, HR, AND PERCENTAGE MAXIMAL HEART RATE (%MHR) WERE 0.45 L.MIN(-1), 7.59 ML.KG(-1).MIN(-1), 14.50%, 2.17 METS, 2.23 KCAL.MIN(-1), 105.29 B.MIN(-1), AND 56.89%, RESPECTIVELY. WHEN COMPARED TO RESTING IN A CHAIR, HATHA YOGA REQUIRED 114% GREATER O(2) (L.MIN(-1)), 111% GREATER O(2)(ML.KG(-1).MIN(-1)), 4,294% GREATER %VO(2)R, 111% GREATER METS, 108% GREATER KCAL.MIN(-1), 24% GREATER HR, AND 24% GREATER %MHR. WHEN COMPARED TO WALKING AT 93.86 M.MIN(-1), HATHA YOGA REQUIRED 54% LOWER O(2)(L.MIN(-1)), 53% LOWER O(2)(ML.KG(-1).MIN(-1)), 68% LOWER %VO(2)R, 53% LOWER METS, 53% LOWER KCAL.MIN(-1), 21% LOWER HR, AND 21% LOWER %MHR. THE HATHA YOGA ROUTINE IN THIS STUDY REQUIRED 14.50% VO(2)R, WHICH CAN BE CONSIDERED A VERY LIGHT INTENSITY AND SIGNIFICANTLY LIGHTER THAN 44.8% VO(2)R FOR WALKING AT 93.86 M.MIN(-1) (3.5 MPH). THE INTENSITY OF HATHA YOGA MAY BE TOO LOW TO PROVIDE A TRAINING STIMULUS FOR IMPROVING CARDIOVASCULAR FITNESS. ALTHOUGH PREVIOUS RESEARCH SUGGESTS THAT HATHA YOGA IS AN ACCEPTABLE FORM OF PHYSICAL ACTIVITY FOR ENHANCING MUSCULAR FITNESS AND FLEXIBILITY, THESE DATA DEMONSTRATE THAT HATHA YOGA MAY HAVE LITTLE, IF ANY, CARDIOVASCULAR BENEFIT. 2005
10 995 46 EFFECTS OF HIGH-INTENSITY HATHA YOGA ON CARDIOVASCULAR FITNESS, ADIPOCYTOKINES, AND APOLIPOPROTEINS IN HEALTHY STUDENTS: A RANDOMIZED CONTROLLED STUDY. BACKGROUND: YOGA EXERCISES ARE OFTEN USED AS A FORM OF BODY AND MIND EXERCISE TO INCREASE PERFORMANCE. HOWEVER, KNOWLEDGE ABOUT THE PHYSIOLOGIC EFFECTS OF PERFORMING HIGH-INTENSITY HATHA YOGA EXERCISES OVER A LONGER TIME PERIOD REMAINS LIMITED. OBJECTIVE: TO INVESTIGATE THE EFFECTS OF HIGH-INTENSITY YOGA (HIY) ON CARDIOVASCULAR FITNESS (MAXIMAL OXYGEN CONSUMPTION, ESTIMATED FROM THE COOPER RUNNING TEST), RATINGS OF PERCEIVED EXERTION (RPE), HEART RATE (HR), HEART RATE RECOVERY (HRR), BLOOD PRESSURE (BP), ADIPOCYTOKINES, APOLIPOPROTEIN A1 (APOA1), APOLIPOPROTEIN B (APOB), AND GLYCOSYLATED HEMOGLOBIN (HBA1C) IN HEALTHY STUDENTS. METHODS: THE 44 PARTICIPANTS (38 WOMEN AND 6 MEN; MEDIAN AGE, 25 YEARS [RANGE, 20-39 YEARS]) WERE RANDOMLY ASSIGNED TO AN HIY OR A CONTROL GROUP. THE HIY PROGRAM WAS HELD FOR 6 WEEKS (60 MINUTES ONCE A WEEK). CARDIOVASCULAR FITNESS, RPE, HR, HRR, BP, ADIPOCYTOKINES, HBA1C, APOA1, AND APOB WERE MEASURED AT BASELINE AND AFTER 6 WEEKS IN BOTH GROUPS. RESULTS: HIY HAD NO SIGNIFICANT EFFECTS ON CARDIOVASCULAR FITNESS (MEAN DOSE: 390 MINUTES [RANGE, 210-800 MINUTES]), HR, HRR, BP, OR ANY OF THE BLOOD PARAMETERS. HOWEVER, SECONDARY FINDINGS SHOWED THAT [CORRECTED] APOA1 (1.47 +/- 0.17 TO 1.55 +/- 0.16 G/L; P = 0.03) AND ADIPONECTIN (8.32 +/- 3.32 TO 9.68 +/- 3.83 MG/L; P = 0.003) LEVELS INCREASED SIGNIFICANTLY IN THE HIY GROUP AFTER 6 WEEKS. CONCLUSIONS: SIX WEEKS OF HIY DID NOT SIGNIFICANTLY IMPROVE CARDIOVASCULAR FITNESS. HOWEVER, SECONDARY FINDINGS SHOWED THAT [CORRECTED] APOA1 AND ADIPONECTIN LEVELS INCREASED SIGNIFICANTLY IN THE HIY GROUP. THIS FINDING SUGGESTS THAT HIY MAY HAVE POSITIVE EFFECTS ON BLOOD LIPIDS AND AN ANTI-INFLAMMATORY EFFECT. 2016
11 642 39 DOES PRACTICING HATHA YOGA SATISFY RECOMMENDATIONS FOR INTENSITY OF PHYSICAL ACTIVITY WHICH IMPROVES AND MAINTAINS HEALTH AND CARDIOVASCULAR FITNESS? BACKGROUND: LITTLE IS KNOWN ABOUT THE METABOLIC AND HEART RATE RESPONSES TO A TYPICAL HATHA YOGA SESSION. THE PURPOSES OF THIS STUDY WERE 1) TO DETERMINE WHETHER A TYPICAL YOGA PRACTICE USING VARIOUS POSTURES MEETS THE CURRENT RECOMMENDATIONS FOR LEVELS OF PHYSICAL ACTIVITY REQUIRED TO IMPROVE AND MAINTAIN HEALTH AND CARDIOVASCULAR FITNESS; 2) TO DETERMINE THE RELIABILITY OF METABOLIC COSTS OF YOGA ACROSS SESSIONS; 3) TO COMPARE THE METABOLIC COSTS OF YOGA PRACTICE TO THOSE OF TREADMILL WALKING. METHODS: IN THIS OBSERVATIONAL STUDY, 20 INTERMEDIATE-TO-ADVANCED LEVEL YOGA PRACTITIONERS, AGE 31.4 +/- 8.3 YEARS, PERFORMED AN EXERCISE ROUTINE INSIDE A HUMAN RESPIRATORY CHAMBER (INDIRECT CALORIMETER) WHILE WEARING HEART RATE MONITORS. THE EXERCISE ROUTINE CONSISTED OF 30 MINUTES OF SITTING, 56 MINUTES OF BEGINNER-LEVEL HATHA YOGA ADMINISTERED BY VIDEO, AND 10 MINUTES OF TREADMILL WALKING AT 3.2 AND 4.8 KPH EACH. MEASURES WERE MEAN OXYGEN CONSUMPTION (VO2), HEART RATE (HR), PERCENTAGE PREDICTED MAXIMAL HEART RATE (%MHR), METABOLIC EQUIVALENTS (METS), AND ENERGY EXPENDITURE (KCAL). SEVEN SUBJECTS REPEATED THE PROTOCOL SO THAT MEASUREMENT RELIABILITY COULD BE ESTABLISHED. RESULTS: MEAN VALUES ACROSS THE ENTIRE YOGA SESSION FOR VO2, HR, %MHR, METS, AND ENERGY/MIN WERE 0.6 L/KG/MIN; 93.2 BEATS/MIN; 49.4%; 2.5; AND 3.2 KCAL/MIN; RESPECTIVELY. RESULTS OF THE ICCS (2,1) FOR MEAN VALUES ACROSS THE ENTIRE YOGA SESSION FOR KCAL, METS, AND %MHR WERE 0.979 AND 0.973, AND 0.865, RESPECTIVELY. CONCLUSION: METABOLIC COSTS OF YOGA AVERAGED ACROSS THE ENTIRE SESSION REPRESENT LOW LEVELS OF PHYSICAL ACTIVITY, ARE SIMILAR TO WALKING ON A TREADMILL AT 3.2 KPH, AND DO NOT MEET RECOMMENDATIONS FOR LEVELS OF PHYSICAL ACTIVITY FOR IMPROVING OR MAINTAINING HEALTH OR CARDIOVASCULAR FITNESS. YOGA PRACTICE INCORPORATING SUN SALUTATION POSTURES EXCEEDING THE MINIMUM BOUT OF 10 MINUTES MAY CONTRIBUTE SOME PORTION OF SUFFICIENTLY INTENSE PHYSICAL ACTIVITY TO IMPROVE CARDIO-RESPIRATORY FITNESS IN UNFIT OR SEDENTARY INDIVIDUALS. THE MEASUREMENT OF ENERGY EXPENDITURE ACROSS YOGA SESSIONS IS HIGHLY RELIABLE. 2007
12 1693 26 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
13 788 47 EFFECT OF YOGA COMBINED WITH AEROBIC EXERCISE INTERVENTION ON MORPHOLOGICAL AND BLOOD LIPID INDICATORS IN FEMALE COLLEGE STUDENTS. BACKGROUND: REGULAR AEROBIC EXERCISE CAN EFFECTIVELY INCREASE MICROVASCULAR FUNCTION IN SKELETAL MUSCLE AND PROMOTE THE OXIDATION OF FATTY ACIDS. HOWEVER, WHETHER THE EFFECT OF AEROBIC EXERCISE INTERVENTION IS AFFECTED BY FAT CONTENT IS WORTH OF FURTHER EXPLORATION. IN THIS STUDY, BY MEANS OF YOGA COMBINED WITH EXERCISE, THE AUTHORS EXPLORED THE EFFECT OF AEROBIC EXERCISE ON MORPHOLOGY AND BLOOD LIPIDS IN FEMALE COLLEGE STUDENTS. METHODS: A TOTAL OF 81 FEMALE COLLEGE STUDENTS WHO VOLUNTARILY PARTICIPATED IN THIS STUDY WERE ENROLLED BY BODY MASS INDEX (BMI) OBTAINED FROM THE PHYSICAL EXAMINATION WHEN ENTERING THE SCHOOL. THE PARTICIPANTS WERE ASSIGNED TO NORMAL (BMI: 20.98+/-1.52 KG/M2, N.=29), OVERWEIGHT (BMI: 25.57+/-1.34 KG/M2, N.=27), AND OBESITY (BMI: 28.46+/-2.36 KG/M2, N.=25) GROUPS BY BMI, AND ALL OF THEM COMPLETED A 12-WEEK YOGA COMBINED WITH AEROBIC EXERCISE TRAINING PROGRAM. RELEVANT MORPHOLOGICAL SUCH AS BODY WEIGHT, BODY HEIGHT, WAIST CIRCUMFERENCE, HIP CIRCUMFERENCE, ETC. AND BLOOD LIPID INDICATORS SUCH AS LOW-DENSITY LIPOPROTEIN CHOLESTEROL (LDL-C), HIGH-DENSITY LIPOPROTEIN CHOLESTEROL (HDL-C), TOTAL CHOLESTEROL (TC) AND TRIGLYCERIDE (TG) WERE MEASURED BEFORE AND AFTER TRAINING. ONE-WAY ANVOA, PAIRED-SAMPLE T-TEST WERE USED IN THIS STUDY. RESULTS: AFTER TRAINING PROGRAM, THE RESULTS INDICATED THAT: 1) THE HIP, BODY WEIGHT, BMI AND BODY FAT PERCENTAGE IN ALL THREE GROUPS SIGNIFICANTLY DECREASED; 2) WAIST CIRCUMFERENCE IN NORMAL AND OBESITY GROUPS HAD A SIGNIFICANT CHANGE THAN THAT IN OVERWEIGHT GROUP, HIP CIRCUMFERENCE AND WAIST-TO-HIP RATIO (WHR) IN OVERWEIGHT GROUP WERE BETTER THAN THOSE IN NORMAL AND OVERWEIGHT GROUPS; THE DECREASE IN BMI IN OVERWEIGHT AND OBESITY GROUPS WAS SIGNIFICANTLY GREATER THAN THAT IN NORMAL GROUP, AND THE WEIGHT LOSS AND DECREASED BODY FAT PERCENTAGE IN OBESITY GROUP WERE THE HIGHEST, FOLLOWED BY OVERWEIGHT GROUP, AND THE SMALLEST IN NORMAL GROUP; 3) IN ALL THREE GROUPS, HDL-C SIGNIFICANTLY INCREASED, LDL-C, TC/HDL-C, TG/HDL-C AND LDL-C/HDL-C SIGNIFICANTLY DECREASED, TC AND TG SIGNIFICANTLY DECREASED IN OBESITY GROUP; AND 4) TC/HDL-C AND TG/HDL-C IN OBESITY GROUP WERE SIGNIFICANTLY HIGHER THAN THOSE IN NORMAL AND OVERWEIGHT GROUPS, WHILE CHANGE IN TC AND TG WERE THE HIGHEST IN OBESITY GROUP, THE SECOND THE OVERWEIGHT GROUP, AND THE LOWEST IN NORMAL GROUP. CONCLUSIONS: TWELVE-WEEK YOGA COMBINED WITH AEROBIC EXERCISE TRAINING HAS A SIGNIFICANT POSITIVE EFFECT ON MORPHOLOGICAL AND BLOOD LIPID INDICATORS IN FEMALE COLLEGE STUDENTS. THE YOGA COMBINED WITH AEROBIC EXERCISE TRAINING CAN BE RECOMMENDED FOR YOUNG WOMEN WITH OVERWEIGHT AND OBESITY POPULATION. 2020
14 1147 38 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
15 880 26 EFFECT OF YOGA TRAINING ON HANDGRIP, RESPIRATORY PRESSURES AND PULMONARY FUNCTION. ALTHOUGH THERE ARE A NUMBER OF REPORTS ON THE EFFECT OF YOGA TRAINING ON PULMONARY FUNCTIONS, VERY FEW STUDIES HAVE BEEN UNDERTAKEN ON THE EFFECT OF YOGA TRAINING ON RESPIRATORY PRESSURES AND HANDGRIP ENDURANCE. HENCE THE PRESENT WORK WAS PLANNED TO STUDY THE EFFECT OF YOGA TRAINING ON HAND GRIP STRENGTH (HGS), HAND GRIP ENDURANCE (HGE), MAXIMUM EXPIRATORY PRESSURE (MEP), MAXIMUM INSPIRATORY PRESSURE (MIP), FORCED EXPIRATORY VOLUME (FEV), FORCED EXPIRATORY VOLUME IN FIRST SECOND (FEV1) AND PEAK EXPIRATORY FLOW RATE (PEFR). 20 SCHOOL CHILDREN IN THE AGE GROUP OF 12 TO 15 YEARS WERE GIVEN YOGA TRAINING (ASANS AND PRANAYAMS) FOR 6 MONTHS. 20 AGE AND GENDER-MATCHED STUDENTS FORMED THE CONTROL GROUP. YOGA TRAINING PRODUCED STATISTICALLY SIGNIFICANT (P < 0.05) INCREASE IN HGS AND HGE. MEP, MIP, FEV, FEV1 AND PEFR ALSO INCREASED SIGNIFICANTLY (P < 0.001) AFTER THE YOGA TRAINING. IN CONTRAST, THE INCREASE IN THESE PARAMETERS IN THE CONTROL GROUP WAS STATISTICALLY INSIGNIFICANT. OUR STUDY SHOWS THAT YOGA TRAINING FOR 6 MONTHS IMPROVES LUNG FUNCTION, STRENGTH OF INSPIRATORY AND EXPIRATORY MUSCLES AS WELL AS SKELETAL MUSCLE STRENGTH AND ENDURANCE. IT IS SUGGESTED THAT YOGA BE INTRODUCED AT SCHOOL LEVEL IN ORDER TO IMPROVE PHYSIOLOGICAL FUNCTIONS, OVERALL HEALTH AND PERFORMANCE OF STUDENTS. 2003
16 1970 37 SHORT TERM HEALTH IMPACT OF A YOGA AND DIET CHANGE PROGRAM ON OBESITY. BACKGROUND: OBESE PERSONS OFTEN FIND PHYSICAL ACTIVITY DIFFICULT. THE EFFECTS OF A YOGA AND DIET CHANGE PROGRAM, EMPHASIZING BREATHING TECHNIQUES PRACTICED WHILE SEATED, WAS ASSESSED IN OBESE PERSONS. MATERIAL/METHODS: A SINGLE GROUP OF 47 PERSONS WERE ASSESSED ON THE FIRST AND LAST DAY OF A YOGA AND DIET CHANGE PROGRAM, WITH 6 DAYS OF THE INTERVENTION BETWEEN ASSESSMENTS. THE ASSESSMENTS WERE: BODY MASS INDEX (BMI), WAIST AND HIP CIRCUMFERENCES, MID-ARM CIRCUMFERENCE, BODY COMPOSITION, HAND GRIP STRENGTH, POSTURAL STABILITY, SERUM LIPID PROFILE AND FASTING SERUM LEPTIN LEVELS. PARTICIPANTS PRACTICED YOGA FOR 5 HOURS EVERY DAY AND HAD A LOW FAT, HIGH FIBER, VEGETARIAN DIET. LAST AND FIRST DAY DATA WERE COMPARED USING A T-TEST FOR PAIRED DATA. RESULTS: FOLLOWING THE 6-DAY RESIDENTIAL PROGRAM, PARTICIPANTS SHOWED A DECREASE IN BMI (1.6 PERCENT), WAIST AND HIP CIRCUMFERENCES, FAT-FREE MASS, TOTAL CHOLESTEROL (7.7 PERCENT DECREASE), HIGH DENSITY LIPOPROTEIN (HDL) CHOLESTEROL (8.7 PERCENT DECREASE), FASTING SERUM LEPTIN LEVELS (44.2 PERCENT DECREASE) AND AN INCREASE IN POSTURAL STABILITY AND HAND GRIP STRENGTH (P<0.05, ALL COMPARISONS). CONCLUSIONS: A 6-DAY YOGA AND DIET CHANGE PROGRAM DECREASED THE BMI AND THE FAT-FREE MASS. TOTAL CHOLESTEROL ALSO DECREASED DUE TO REDUCED HDL LEVELS. THIS SUGGESTS THAT A BRIEF, INTENSIVE YOGA PROGRAM WITH A CHANGE IN DIET CAN POSE CERTAIN RISKS. BENEFITS SEEN WERE BETTER POSTURAL STABILITY, GRIP STRENGTH (THOUGH A 'PRACTICE EFFECT' WAS NOT RULED OUT), REDUCED WAIST AND HIP CIRCUMFERENCES AND A DECREASE IN SERUM LEPTIN LEVELS. 2010
17 1298 33 HATHA YOGA AND VASCULAR FUNCTION: RESULTS FROM CROSS-SECTIONAL AND INTERVENTIONAL STUDIES. THE AIM OF THIS STUDY WAS TO DETERMINE THE EFFECT OF HATHA YOGA ON ARTERIAL ELASTICITY AND ENDOTHELIAL FUNCTION. FIRST, A CROSS-SECTIONAL STUDY WAS PERFORMED TO DETERMINE WHETHER YOGA PRACTITIONERS WOULD DEMONSTRATE GREATER ARTERIAL COMPLIANCE AND ENDOTHELIUM-DEPENDENT VASODILATION THAN THEIR SEDENTARY PEERS. SECOND, AN INTERVENTION STUDY INVOLVING 13 SEDENTARY MIDDLE-AGED AND OLDER ADULTS (51 +/- 7 YEARS) WAS PERFORMED TO DETERMINE WHETHER 12 WEEKS OF HATHA YOGA WOULD ELICIT INCREASES IN ARTERIAL COMPLIANCE AND ENDOTHELIAL FUNCTION. IN THE CROSS-SECTIONAL STUDY INVOLVING A TOTAL OF 34 SUBJECTS, THERE WERE NO GROUP DIFFERENCES IN BODY FATNESS, BLOOD LIPID AND LIPOPROTEIN CONCENTRATIONS, CAROTID ARTERY COMPLIANCE OR BRACHIAL ARTERY FLOW-MEDIATED DILATION (FMD). HEMOGLOBIN A1C WAS LOWER IN YOGA PRACTITIONERS THAN IN SEDENTARY ADULTS (P < 0.05). TOTAL CHOLESTEROL AND HEMOGLOBIN A1C DECREASED AFTER THE INTERVENTION (P < 0.05) WHILE CAROTID ARTERY COMPLIANCE AND BRACHIAL ARTERY FMD DID NOT CHANGE. THE RESULTS OF BOTH CROSS-SECTIONAL AND INTERVENTIONAL STUDIES INDICATE THAT REGULAR PRACTICE OF HATHA YOGA IS NOT ASSOCIATED WITH IMPROVEMENTS IN VASCULAR FUNCTIONS. 2013
18 2463 48 YOGA AS A THERAPEUTIC INTERVENTION FOR THE MANAGEMENT OF TYPE 2 DIABETES MELLITUS. PURPOSE: THIS STUDY AIMED TO INVESTIGATE THE EFFECTS OF 12 WEEKS YOGIC INTERVENTION ON BLOOD SUGAR AND LIPID PROFILE IN ELDER WOMEN WITH TYPE 2 DIABETES MELLITUS (T2DM). SUBJECTS AND METHODS: TWENTY ELDERLY (AGE RANGE 55-70 YEARS) T2DM WOMEN WERE DIVIDED INTO TWO GROUPS, NAMELY, YOGIC INTERVENTION GROUP (YIG: N = 10, AGE 64.70 +/- 4.03, BODY MASS INDEX [BMI] 24.26 +/- 3.40) AND CONTROL GROUP (CG: N = 10, AGE 64.40 +/- 4.79, BMI 24.28 +/- 2.36). YIG UNDERWENT YOGA PRACTICE (ASANAS, KRIYAS, PRANAYAMAS) FOR 12 WEEKS (3 SESSIONS/WEEK), WHILE THE CG CONTINUED THEIR USUAL ROUTINE ACTIVITIES. STANDING HEIGHT, BODY WEIGHT, BMI, BLOOD SUGAR, AND LIPID PROFILE WERE MEASURED BEFORE COMMENCEMENT AND AFTER 6 AND 12 WEEKS OF YOGIC INTERVENTION IN BOTH GROUPS. RESULTS: THERE WAS A SIGNIFICANT (P < 0.01) DECREASE IN FASTING PLASMA GLUCOSE, POSTPRANDIAL BLOOD SUGAR, TOTAL CHOLESTEROL, TRIGLYCERIDES, LOW-DENSITY LIPOPROTEIN, AND VERY LOW DENSITY LIPOPROTEIN, WITH A SIGNIFICANT (P < 0.01) INCREASE IN HIGH-DENSITY LIPOPROTEIN LEVEL FROM ITS INITIAL VALUE IN YIG, WHILE SHOWING INSIGNIFICANT RESULT IN CG. CONCLUSION: IT CAN BE SAID THAT YOGIC INTERVENTION MAY HAVE THE BENEFICIAL EFFECTS ON BLOOD SUGAR AND LIPID PROFILE IN ELDERLY WOMEN WITH T2DM. 2018
19 323 26 ANTHROPOMETRIC AND PHYSIOLOGIC PROFILES OF FEMALE PROFESSIONAL YOGA PRACTITIONERS AND ENERGY EXPENDITURE DURING ASANAS EXECUTION. AIM: THE PRESENT STUDY AIMED TO: 1) DEFINE THE ANTHROPOMETRIC AND PHYSIOLOGICAL PROFILES OF FEMALE PROFESSIONAL YOGA PRACTITIONER COMPARED TO THAT OF OTHER ATHLETES; 2) EVALUATE THE ENERGY EXPENDITURE (EE) DURING A YOGA SESSION. METHODS: THE PERCENTAGE FAT MASS (FM%) AND FAT FREE MASS (FFM%), THE MAXIMAL AEROBIC POWER (VO2MAX), THE MAXIMAL VOLUNTARY CONTRACTION (MVC) OF KNEE EXTENSOR MUSCLES AND THE MAXIMAL ANAEROBIC ALACTACID POWER (WMAX) WERE ASSESSED IN A GROUP OF YOGA PRACTITIONERS (YO), LONG DISTANCE RUNNERS (LDR), SPRINTERS (SPR), KARATE PRACTITIONERS (KA) AND SEDENTARY CONTROL SUBJECTS (CON). EE WAS EVALUATED IN YO DURING A YOGA SESSION (EXECUTION OF A SEQUENCE OF SIX YOGA POSTURES, CALLED ASANAS). RESULTS: FM% WAS SIGNIFICANTLY HIGHER IN CON (24.2+/-2.6%) THAN IN OTHER GROUPS (18+/-1.9%, POOLED DATA, P<0.05). FFM% DID NOT DIFFER AMONG GROUPS. VO2MAX WAS HIGHER IN LDR (55.6+/-1.8 ML MIN-1 KG-1) COMPARED TO OTHER GROUPS (41.7+/-3 ML MIN-1 KG-1, POOLED DATA, P<0.05). MVC AND WMAX WERE HIGHER IN YO, SPR AND KA THAN IN LDR AND CON (P<0.05). IN YO, EE INCREASED IN COMPARISON TO BASELINE, DURING SIRASANA EXECUTION ONLY (+59%, P<0.05). CONCLUSION: THESE DATA SUGGEST THAT CHRONIC YOGA PRACTICE IS ASSOCIATED WITH 1) VALUES OF FM%, FFM%, MVC AND WMAX SIMILAR TO THOSE INDUCED BY SPORTS REQUIRING HIGH DEGREE OF FORCE AND POWER OF LOWER LIMB MUSCLES, WITH MAXIMAL AEROBIC PERFORMANCE SIMILAR TO CONTROL SUBJECTS; 2) LOW EE DURING MOST ASANAS EXECUTION. 2015
20 439 30 CARDIOVASCULAR, CELLULAR, AND NEURAL ADAPTATIONS TO HOT YOGA VERSUS NORMAL-TEMPERATURE YOGA. CONTEXT: CHRONIC HEAT EXPOSURE PROMOTES CARDIOVASCULAR AND CELLULAR ADAPTATIONS, IMPROVING AN ORGANISM'S ABILITY TO TOLERATE SUBSEQUENT STRESSORS. HEAT EXPOSURE MAY ALSO PROMOTE NEURAL ADAPTATIONS AND ALTER THE NEURAL-HORMONAL STRESS RESPONSE. HOT-TEMPERATURE YOGA (HY) COMBINES MIND-BODY EXERCISE WITH HEAT EXPOSURE. THE ADDED HEAT COMPONENT IN HY MAY INDUCE CARDIOVASCULAR AND CELLULAR CHANGES, ALONG WITH NEURAL BENEFITS AND MODULATION OF STRESS HORMONES. AIMS: THE PURPOSE OF THE PRESENT STUDY IS TO COMPARE THE CARDIOVASCULAR, CELLULAR HEAT SHOCK PROTEIN 70 (HSP70), NEURAL, AND HORMONAL ADAPTATIONS OF HY VERSUS NORMAL-TEMPERATURE YOGA (NY). SETTINGS AND DESIGN: TWENTY-TWO SUBJECTS (MALES = 11 AND FEMALES = 11, 26 +/- 6 YEARS) COMPLETED 4 WEEKS OF NY (N = 11) OR HY (N = 11, 41 DEGREES C, 40% HUMIDITY). YOGA SESSIONS WERE PERFORMED 3 TIMES/WEEK FOLLOWING A MODIFIED BIKRAM PROTOCOL. SUBJECTS AND METHODS: PRE- AND POSTTESTING INCLUDED (1) HEMODYNAMIC MEASURES DURING A HEAT TOLERANCE TEST AND MAXIMAL AEROBIC FITNESS TEST; (2) NEURAL AND HORMONAL ADAPTATIONS USING SERUM BRAIN-DERIVED NEUROTROPHIC FACTOR (BDNF) AND ADRENOCORTICOTROPIC HORMONE (ACTH), ALONG WITH A MENTAL STRESS QUESTIONNAIRE; AND (3) CELLULAR ADAPTATIONS (HSP70) IN PERIPHERAL BLOOD MONONUCLEAR CELLS (PBMCS). STATISTICAL ANALYSIS: WITHIN- AND BETWEEN-GROUP STUDENT'S T-TEST ANALYSES WERE CONDUCTED TO COMPARE PRE- AND POST-VO2 MAX, PERCEIVED STRESS, BDNF, HSP70, AND ACTH IN HY AND NY GROUPS. RESULTS: MAXIMAL AEROBIC FITNESS INCREASED IN THE HY GROUP ONLY. NO EVIDENCE OF HEAT ACCLIMATION OR CHANGE IN MENTAL STRESS WAS OBSERVED. SERUM BDNF SIGNIFICANTLY INCREASED IN YOGA GROUPS COMBINED. ANALYSIS OF HSP70 SUGGESTED HIGHER EXPRESSION OF HSP70 IN THE HY GROUP ONLY. CONCLUSIONS: TWELVE SESSIONS OF HY PROMOTED CARDIOVASCULAR FITNESS AND CELLULAR THERMOTOLERANCE ADAPTATIONS. SERUM BDNF INCREASED IN RESPONSE TO YOGA (NY + HY) AND APPEARED TO NOT BE TEMPERATURE DEPENDENT. 2021
