1 1948 120 SCAPULAR MUSCLE ACTIVITY DURING STATIC YOGA POSTURES. STUDY DESIGN CONTROLLED, CROSS-SECTIONAL LABORATORY STUDY. BACKGROUND DESPITE THE GROWING POPULARITY OF YOGA, LITTLE IS KNOWN ABOUT THE MUSCLE ACTIVITY OF THE SCAPULAR STABILIZERS DURING ISOMETRIC YOGA POSTURES AND THEIR POTENTIAL UTILITY IN SHOULDER REHABILITATION. OBJECTIVES TO EXAMINE SCAPULAR STABILIZER MUSCLE ACTIVATION DURING VARIOUS YOGA POSTURES. METHODS TWENTY WOMEN WITH YOGA EXPERIENCE AND NO SHOULDER PAIN OR INJURY PARTICIPATED. ELECTROMYOGRAPHY WAS USED TO RECORD THE MUSCLE ACTIVITY OF THE UPPER, MIDDLE, AND LOWER TRAPEZIUS, AS WELL AS OF THE SERRATUS ANTERIOR, DURING 15 YOGA POSTURES. RESULTS MUSCLE ACTIVITY VARIED BETWEEN YOGA POSTURES (3%-57% MAXIMUM VOLUNTARY ISOMETRIC CONTRACTION [MVIC]). OVERALL, THE "LOCUST ARMS FORWARD" POSTURE ELICITED THE HIGHEST ACTIVITY FROM THE UPPER (22.4% MVIC), MIDDLE (41.8% MVIC), AND LOWER (56.8% MVIC) TRAPEZIUS, WHILE SEVERAL POSTURES ELICITED MODERATE ACTIVITY (GREATER THAN 20% MVIC) FROM THE SERRATUS ANTERIOR. CONVERSELY, THE "DANCER'S POSE RIGHT," "REVERSE TABLETOP," AND "WARRIOR II" POSTURES DEMONSTRATED LOW ACTIVITY (LESS THAN OR EQUAL TO 15.7% MVIC) OF THE SCAPULAR STABILIZERS. CONCLUSION STRENGTHENING THE SCAPULAR STABILIZER MUSCLES IS AN IMPORTANT COMPONENT OF SHOULDER REHABILITATION. YOGA POSTURES HAVE BEEN IDENTIFIED THAT ACTIVATE THE SCAPULAR STABILIZER MUSCLES AT VARYING LEVELS OF ACTIVITY. J ORTHOP SPORTS PHYS THER 2018;48(6):504-509. EPUB 6 APR 2018.

2 1283  40 GLUTEAL MUSCLE ACTIVATION DURING COMMON YOGA POSES. BACKGROUND: APPROXIMATELY 24% OF PHYSICAL THERAPISTS REPORT REGULARLY USING YOGA TO STRENGTHEN MAJOR MUSCLE GROUPS. ALTHOUGH CLINICIANS AND ATHLETES OFTEN USE YOGA AS A FORM OF STRENGTH TRAINING, LITTLE IS KNOWN ABOUT THE ACTIVATION OF SPECIFIC MUSCLE GROUPS DURING YOGA POSES, INCLUDING THE GLUTEUS MAXIMUS AND MEDIUS. HYPOTHESIS/PURPOSE: THE PURPOSE OF THIS STUDY WAS TO MEASURE GLUTEUS MAXIMIMUS AND GLUTEUS MEDIUS ACTIVATION VIA ELECTROMYOGRAPHY (EMG) DURING FIVE COMMON YOGA POSES. A SECONDARY PURPOSE OF THE CURRENT STUDY WAS TO EXAMINE DIFFERENCES IN MUSCLE ACTIVATION BETWEEN SEXES AND EXPERIENCE LEVELS. STUDY DESIGN: CROSS-SECTIONAL. METHODS: THIRTY-ONE HEALTHY MALES AND FEMALES AGED 18-35 YEARS WERE TESTED DURING FIVE YOGA POSES PERFORMED IN A RANDOMIZED ORDER. SURFACE EMG ELECTRODES WERE PLACED ON SUBJECTS' RIGHT GLUTEUS MAXIMUS AND GLUTEUS MEDIUS. SUBJECTS PERFORMED THE POSES ON BOTH SIDES FOLLOWING A MAXIMAL VOLUNTARY ISOMETRIC CONTRACTION (MVIC) TEST FOR EACH MUSCLE. ALL YOGA POSE EMG DATA WERE NORMALIZED TO THE CORRESPONDING MUSCLE MVIC DATA. RESULTS: HIGHEST GLUTEUS MAXIMUS ACTIVATION OCCURRED DURING HALF MOON POSE ON THE LIFTED/BACK LEG (63.3% MVIC), FOLLOWED BY THE STANCE/FRONT LEG DURING HALF MOON POSE (61.7%), THEN THE LIFTED/BACK LEG DURING WARRIOR THREE POSE (46.1%). HIGHEST GLUTEUS MEDIUS ACTIVATION OCCURRED DURING HALF MOON POSE ON THE LIFTED/BACK LEG (41.9%), FOLLOWED BY THE LIFTED/BACK LEG DURING THE WARRIOR THREE POSE (41.6%). A SIGNIFICANT DIFFERENCE WAS FOUND IN %MVIC OF GLUTEUS MEDIUS ACTIVITY BETWEEN MALE AND FEMALE SUBJECTS (P = 0.026), AND BETWEEN EXPERIENCED AND INEXPERIENCED SUBJECTS (P = 0.050), INDICATING HIGHER ACTIVATION AMONG MALES AND INEXPERIENCED SUBJECTS, RESPECTIVELY. CONCLUSION: HALF MOON POSE AND WARRIOR THREE POSE ELICITED THE HIGHEST ACTIVATION FOR BOTH THE GLUTEUS MAXIMUS AND THE GLUTEUS MEDIUS. HIGHER GLUTEUS MEDIUS ACTIVATION WAS SEEN IN MALES AND INEXPERIENCED SUBJECTS COMPARED TO THEIR FEMALE AND EXPERIENCED COUNTERPARTS.

3 1654  33 MUSCLE UTILIZATION PATTERNS VARY BY SKILL LEVELS OF THE PRACTITIONERS ACROSS SPECIFIC YOGA POSES (ASANAS). OBJECTIVE: TO COMPARE MUSCLE ACTIVATION PATTERNS IN 14 DOMINANT SIDE MUSCLES DURING DIFFERENT YOGA POSES ACROSS THREE SKILL LEVELS. DESIGN: MIXED REPEATED-MEASURES DESCRIPTIVE STUDY. SETTING: UNIVERSITY NEUROMUSCULAR RESEARCH LABORATORY, MIAMI, US. PARTICIPANTS: A GROUP OF 36 YOGA PRACTITIONERS (9 M/27 F; MEAN +/- SD, 31.6 +/- 12.6 YEARS) WITH AT LEAST 3 MONTHS YOGA PRACTICE EXPERIENCE. INTERVENTIONS: EACH OF THE 11 SURYA NAMASKAR POSES A AND B WAS PERFORMED SEPARATELY FOR 15S AND THE SURFACE ELECTROMYOGRAPHY FOR 14 MUSCLES WERE RECORDED. MAIN OUTCOME MEASURES: NORMALIZED ROOT MEAN SQUARE OF THE ELECTROMYOGRAPHIC SIGNAL (NRMSEMG) FOR 14 MUSCLES (5 UPPER BODY, 4 TRUNK, 5 LOWER BODY). RESULTS: THERE WERE SIGNIFICANT MAIN EFFECTS OF POSE FOR ALL FOURTEEN MUSCLES EXCEPT MIDDLE TRAPEZIUS (P<.02) AND OF SKILL LEVEL FOR THE VASTUS MEDIALIS; P=.027). A SIGNIFICANT SKILL LEVEL X POSE INTERACTION EXISTED FOR FIVE MUSCLES (PECTORALIS MAJOR STERNAL HEAD, ANTERIOR DELTOID, MEDIAL DELTOID, UPPER RECTUS ABDOMINIS AND GASTROCNEMIUS LATERALIS; P<.05). POST HOC ANALYSES USING BONFERRONI COMPARISONS INDICATED THAT DIFFERENT POSES ACTIVATED SPECIFIC MUSCLE GROUPS; HOWEVER, THIS VARIED BY SKILL LEVEL. CONCLUSION: OUR RESULTS INDICATE THAT DIFFERENT POSES CAN PRODUCE SPECIFIC MUSCLE ACTIVATION PATTERNS WHICH MAY VARY DUE TO PRACTITIONERS' SKILL LEVELS. THIS INFORMATION CAN BE USED IN DESIGNING REHABILITATION AND TRAINING PROGRAMS AND FOR CUING DURING YOGA TRAINING.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
4  626  34 DIFFERENCE IN MUSCLE ACTIVATION PATTERNS DURING HIGH-SPEED VERSUS STANDARD-SPEED YOGA: A RANDOMIZED SEQUENCE CROSSOVER STUDY. OBJECTIVES: TO COMPARE THE DIFFERENCE IN MUSCLE ACTIVATION BETWEEN HIGH-SPEED YOGA AND STANDARD-SPEED YOGA AND TO COMPARE MUSCLE ACTIVATION OF THE TRANSITIONS BETWEEN POSES AND THE HELD PHASES OF A YOGA POSE. DESIGN: RANDOMIZED SEQUENCE CROSSOVER TRIAL SETTING: A LABORATORY OF NEUROMUSCULAR RESEARCH AND ACTIVE AGING INTERVENTIONS: EIGHT MINUTES OF CONTINUOUS SUN SALUTATION B WAS PERFORMED, AT A HIGH SPEED VERSUS A STANDARD-SPEED, SEPARATELY. ELECTROMYOGRAPHY WAS USED TO QUANTIFY NORMALIZED MUSCLE ACTIVATION PATTERNS OF EIGHT UPPER AND LOWER BODY MUSCLES (PECTORALIS MAJOR, MEDIAL DELTOIDS, LATERAL HEAD OF THE TRICEPS, MIDDLE FIBERS OF THE TRAPEZIUS, VASTUS MEDIALIS, MEDIAL GASTROCNEMIUS, THORACIC EXTENSOR SPINAE, AND EXTERNAL OBLIQUES) DURING THE HIGH-SPEED AND STANDARD-SPEED YOGA PROTOCOLS. MAIN OUTCOME MEASURES: DIFFERENCE IN NORMALIZED MUSCLE ACTIVATION BETWEEN HIGH-SPEED YOGA AND STANDARD-SPEED YOGA. RESULTS: NORMALIZED MUSCLE ACTIVITY SIGNALS WERE SIGNIFICANTLY HIGHER IN ALL EIGHT MUSCLES DURING THE TRANSITION PHASES OF POSES COMPARED TO THE HELD PHASES (P<0.01). THERE WAS NO SIGNIFICANT INTERACTION BETWEEN SPEEDXPHASE; HOWEVER, GREATER NORMALIZED MUSCLE ACTIVITY WAS SEEN FOR HIGHSPEED YOGA ACROSS THE ENTIRE SESSION. CONCLUSIONS: OUR RESULTS SHOW THAT TRANSITIONS FROM ONE HELD PHASE OF A POSE TO ANOTHER PRODUCES HIGHER NORMALIZED MUSCLE ACTIVITY THAN THE HELD PHASES OF THE POSES AND THAT OVERALL ACTIVITY IS GREATER DURING HIGHSPEED YOGA THAN STANDARD-SPEED YOGA. THEREFORE, THE TRANSITION SPEED AND ASSOCIATED NUMBER OF POSES SHOULD BE CONSIDERED WHEN TARGETING SPECIFIC IMPROVEMENTS IN PERFORMANCE.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
5 2306  30 TRAINING BENEFITS AND INJURY RISKS OF STANDING YOGA APPLIED IN MUSCULOSKELETAL PROBLEMS: LOWER LIMB BIOMECHANICAL ANALYSIS. STANDING YOGA POSES STRENGTHEN A PERSON'S LEGS AND HELPS TO ACHIEVE THE GOAL OF MUSCULOSKELETAL REHABILITATION, BUT INADEQUATE EXERCISE PLANNING CAN CAUSE INJURIES. THIS STUDY INVESTIGATED CHANGES IN THE ELECTROMYOGRAM AND JOINT MOMENTS OF FORCE (JMOFS) OF LOWER EXTREMITIES DURING COMMON STANDING YOGA POSES IN ORDER TO EXPLORE THE FEASIBILITY AND POSSIBLE INJURY RISK IN DEALING WITH MUSCULOSKELETAL PROBLEMS. ELEVEN YOGA INSTRUCTORS WERE RECRUITED TO EXECUTE FIVE YOGA POSES (CHAIR, TREE, WARRIOR 1, 2, AND 3). THE RESULTS REVEALED SIGNIFICANT DIFFERENCES IN HIP, KNEE, AND ANKLE JMOFS AND VARYING DEGREES OF MUSCLE ACTIVATION AMONG THE POSES. AMONG THESE POSES, RECTUS FEMORIS MUSCLE ACTIVATION DURING THE CHAIR POSE WAS THE HIGHEST, WARRIOR 2 PRODUCED THE HIGHEST MUSCLE ACTIVATION IN THE VASTUS LATERALIS OF THE FRONT LIMB, WHILE WARRIOR 1 HAD THE HIGHEST MUSCLE ACTIVATION IN THE VASTUS MEDIALIS OF THE BACK LIMB. THEREFORE, ALL THREE POSES CAN POSSIBLY BE SUGGESTED AS A THERAPEUTIC INTERVENTION FOR QUADRICEPS STRENGTHENING. WARRIOR 1 WAS POSSIBLY SUGGESTED AS A THERAPEUTIC INTERVENTION IN ORDER TO REDUCE EXCESSIVE LATERAL OVERLOAD OF THE PATELLA, BUT THE POSSIBLE ADVERSE EFFECTS OF WARRIOR 2 WITH THE HIGHEST KNEE ADDUCTOR JMOF IN THE BACK LIMB COULD RAISE JOINT REACTION FORCES ACROSS THE MEDIAL CONDYLES. IN SINGLE-LEG BALANCE POSTURES, WARRIOR 3 HAD UNIQUE TRAINING EFFECTS ON THE HAMSTRING, AND IS THEREFORE SUGGESTED AS A PART OF HAMSTRING REHABILITATION EXERCISES. THE TREE POSE INDUCED LOW LOWER-EXTREMITY JMOFS AND A LOW LEVEL OF THIGH MUSCLE ACTIVATIONS WHEN IT WAS PERFORMED BY SENIOR INSTRUCTORS WITH EXCELLENT BALANCE CONTROL; HOWEVER, FOR YOGA BEGINNERS WITH INSUFFICIENT STABILITY, IT WILL BE A USEFUL TRAINING MODE FOR STRENGTHENING THE MUSCLES THAT HELP TO KEEP ONE UPRIGHT. THIS STUDY QUANTIFIED THE PHYSICAL DEMANDS OF YOGA POSES USING BIOMECHANICAL DATA AND ELUCIDATED THE STRUCTURES AND PRINCIPLES UNDERLYING EACH YOGA MOVEMENT. THIS IS CRUCIAL FOR YOGA PRACTITIONERS.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
6 2340  25 USE OF A 'POSE RATE' TO QUANTIFY YOGA. OBJECTIVE: TO DEVELOP A METHOD THAT DESCRIBES THE PHYSICAL ACTIVITY COMPLETED DURING YOGA, AND TO USE THIS METHOD TO COMPARE THREE DIFFERENT YOGA VIDEO CATEGORIES: WEIGHT LOSS, BEGINNER, AND STRESS RELIEF/MEDITATION. DESIGN: THIS STUDY CONDUCTED CONTENT ANALYSIS OF COMMERCIALLY AVAILABLE YOGA VIDEOS IN WHICH PRE-DETERMINED CHARACTERISTICS OF YOGA ROUTINES WERE RECORDED. OUTCOME MEASURES INCLUDED THE YOGA ROUTINE CHARACTERISTICS OF: DURATION OF EACH YOGA ROUTINE, NUMBER OF COMPLETED POSES, BODY POSITION OF EACH POSE, AND POSE RATE. RESULTS: TWENTY-TWO ROUTINES FROM YOGA VIDEOS WERE ANALYZED. DURATION OF ROUTINE BETWEEN THE THREE DIFFERENT CATEGORIES WAS NOT SIGNIFICANTLY DIFFERENT. THERE WERE SIGNIFICANT DIFFERENCES BETWEEN THE VIDEO CATEGORIES BASED ON THE CHARACTERISTICS OF TOTAL NUMBER OF POSES AND THE POSE RATE, WITH WEIGHT LOSS ROUTINES HAVING THE HIGHEST VALUES COMPARE TO BEGINNER ROUTINES AND STRESS RELIEF/MEDITATION (TOTAL NUMBER OF POSES: 74.1, 34.3, 25.6 POSES, P < 0.05; POSE RATE: 2.5M 1.5, 1.1 POSES/MIN, P < 0.05, RESPECTIVELY). ADDITIONALLY, DIFFERENCES WERE OBSERVED BETWEEN BODY POSTURES IN POSES WITH WEIGHT LOSS VIDEOS INCLUDING MORE STANDING POSES (38.8, 17.0, 5.7 POSES, P < 0.05, RESPECTIVELY) AND A LOWER PERCENTAGE OF SEATED (9.9%, 15.8%, 39.0%, P < 0.05, RESPECTIVELY) AND SUPINE POSES (10.9%, 18.5%, 28.8%, P < 0.05, RESPECTIVELY) COMPARED TO THE BEGINNER AND STRESS/MEDITATION VIDEOS. CONCLUSIONS: THE CHARACTERISTICS OF TOTAL POSES, POSE RATE, AND TOTAL STANDING POSES SHOWED SIGNIFICANT DIFFERENCES BETWEEN DIFFERENT STYLES OF YOGA. FURTHER RESEARCH SHOULD BE CONDUCTED TO VALIDATE THESE CHARACTERISTICS AS AN INTENSITY MEASURES AND TO ASSESS IF THESE CHARACTERISTICS HAVE VARIATIONS BETWEEN DIFFERENT YOGA STYLES.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
7  552  35 CORE MUSCLE FUNCTION DURING SPECIFIC YOGA POSES. OBJECTIVE: TO ASSESS THE POTENTIAL USE OF 11 YOGA POSES IN SPECIFIC TRAINING AND REHABILITATION PROGRAMS VIA EXAMINATION OF THE MUSCLE ACTIVATION PATTERNS IN SELECTED TRUNK AND HIP MUSCLES. DESIGN: REPEATED-MEASURES DESCRIPTIVE STUDY. SETTING: UNIVERSITY LABORATORY, US. PARTICIPANTS: THIRTY HEALTHY YOGA PRACTITIONERS WITH MORE THAN 3 MONTHS YOGA PRACTICE EXPERIENCE (MEAN AGE+/-SD, 32.0+/-12.3 Y; 8 M/22 F) PARTICIPATED. INTERVENTIONS: SURFACE ELECTROMYOGRAPHIC SIGNALS OF UPPER RECTUS ABDOMINIS, LOWER RECTUS ABDOMINIS, LONGISSIMUS THORACIS, EXTERNAL OBLIQUE ABDOMINIS AND GLUTEUS MAXIMUM MUSCLE WERE RECORDED IN 11 YOGA POSES: HALFWAY LIFT, FORWARD FOLD, DOWNWARD FACING DOG, UPWARD FACING DOG, HIGH PLANK, LOW PLANK, CHAIR, MOUNTAIN WITH ARMS DOWN, MOUNTAIN WITH ARMS UP, WARRIOR 1 (BOTH SIDES). MAIN OUTCOME MEASURES: ROOT MEAN SQUARE VALUES OF EACH MUSCLE DURING EACH POSE, NORMALIZED BY THE MAXIMAL VOLUNTARY CONTRACTION. RESULTS: THERE WERE SIGNIFICANT MAIN EFFECTS OF POSE (P<.001) AND MUSCLE (P<.001), AND A SIGNIFICANT POSEXMUSCLE INTERACTION (P=.001). THE POST HOC ANALYSIS REVEALED UNIQUE PATTERNS FOR THE FIVE MUSCLES OF INTEREST FOR EACH OF THE 11 POSES (P<.024). CONCLUSIONS: VARIATIONS IN CORE MUSCLE FIRING PATTERNS DEPEND ON THE TRUNK AND PELVIC POSITIONS DURING THESE POSES. TRAINING PROGRAMS CAN BE DEVELOPED BY CHOOSING PARTICULAR POSES TO TARGET SPECIFIC CORE MUSCLES FOR ADDRESSING LOW BACK PAIN AND DECLINES IN PERFORMANCE. THE HIGH PLANK, LOW PLANK AND DOWNWARD FACING DOG POSES ARE EFFECTIVE FOR STRENGTHENING EXTERNAL OBLIQUE ABDOMINIS, CHAIR AND WARRIOR 1 POSES FOR TARGETING GLUTEUS MAXIMUM, AND CHAIR AND HALFWAY LIFT POSES FOR STRENGTHENING LONGISSIMUS THORACIS. AND THESE THREE MUSCLES COULD BE STRENGTHENED BY THE UPWARD FACING DOG POSE.	2014

THUS, WE USED BIOMECHANICAL METHODS TO QUANTIFY THE LOWER EXTREMITY JOINT ANGLES, JOINT MOMENTS OF FORCE, AND MUSCLE ACTIVITIES OF 21 HATHA YOGA POSTURES, COMMONLY USED IN SENIOR YOGA PROGRAMS. TWENTY OLDER ADULTS, 70.7 YEARS +/- 3.8 YEARS, PARTICIPATED IN A 32-WK YOGA CLASS (2 D/WK) WHERE THEY LEARNED INTRODUCTORY AND INTERMEDIATE POSTURES (ASANAS). THEY THEN PERFORMED THE ASANAS IN A MOTION ANALYSIS LABORATORY. KINEMATIC, KINETIC, AND ELECTROMYOGRAPHIC DATA WAS COLLECTED OVER THREE SECONDS WHILE THE PARTICIPANTS HELD THE POSES STATICALLY. PROFILES ILLUSTRATING THE POSTURES AND INCLUDING THE BIOMECHANICAL DATA WERE THEN GENERATED FOR EACH ASANA. OUR FINDINGS DEMONSTRATED THAT HATHA YOGA POSTURES ENGENDERED A RANGE OF APPRECIABLE JOINT ANGLES, JMOFS, AND MUSCLE ACTIVITIES ABOUT THE ANKLE, KNEE, AND HIP, AND THAT DEMANDS ASSOCIATED WITH SOME POSTURES AND POSTURE MODIFICATIONS WERE NOT ALWAYS INTUITIVE. THEY ALSO DEMONSTRATED THAT ALL OF THE POSTURES ELICITED APPRECIABLE RECTUS ABDOMINIS ACTIVITY, WHICH WAS UP TO 70% OF THAT INDUCED DURING WALKING.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
10 2329  28 TRUNK AND HIP MUSCLE ACTIVATION DURING YOGA POSES: IMPLICATIONS FOR PHYSICAL THERAPY PRACTICE. OBJECTIVE: TO DETERMINE AND COMPARE ACTIVATION OF CORE MUSCLES DURING YOGA TO TRADITIONAL BACK EXERCISES. METHODS: SURFACE ELECTROMYOGRAPHY WAS USED TO QUANTIFY ACTIVATION OF THE RECTUS ABDOMINIS (RA), ABDOMINAL OBLIQUES (AO), LUMBAR EXTENSORS (LE), AND GLUTEUS MAXIMUS (GMX) DURING FOUR YOGA POSES. DATA WERE EXPRESSED AS 100% OF A MAXIMUM VOLUNTARY ISOMETRIC CONTRACTION. SEPARATE ANALYSES OF VARIANCE WITH REPEATED MEASURES WERE USED TO COMPARE MUSCLE ACTIVITY ACROSS EACH EXERCISE. RESULTS: SUBJECTS GENERATED GREATER RA (P < 0.0001) AND AO (P < 0.0001) ACTIVITY DURING THE PLANK. THEY GENERATED GREATER AO ACTIVITY (P < 0.0001) DURING THE UPWARD-FACING DOG THAN THE CHAIR AND DOMINANT-SIDE WARRIOR 1. LE ACTIVITY WAS GREATEST (P < 0.0001) DURING THE CHAIR. GMX ACTIVITY WAS SIMILAR (P = 0.09) DURING ALL EXERCISES. CONCLUSION: YOGA POSES MAY HELP IMPROVE CORE ENDURANCE AND STRENGTH. CLINICIANS MAY USE THESE DATA WHEN DEVELOPING AND IMPLEMENTING AN EVIDENCE-BASED CORE EXERCISE PROGRAM FOR INDIVIDUALS WHO PREFER A YOGA TREATMENT STRATEGY.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
11 2736  27 YOGA POSES INCREASE SUBJECTIVE ENERGY AND STATE SELF-ESTEEM IN COMPARISON TO 'POWER POSES'. RESEARCH ON BENEFICIAL CONSEQUENCES OF YOGA FOCUSES ON THE EFFECTS OF YOGIC BREATHING AND MEDITATION. LESS IS KNOWN ABOUT THE PSYCHOLOGICAL EFFECTS OF PERFORMING YOGA POSTURES. THE PRESENT STUDY INVESTIGATED THE EFFECTS OF YOGA POSES ON SUBJECTIVE SENSE OF ENERGY AND SELF-ESTEEM. THE EFFECTS OF YOGA POSTURES WERE COMPARED TO THE EFFECTS OF 'POWER POSES,' WHICH ARGUABLY INCREASE THE SENSE OF POWER AND SELF-CONFIDENCE DUE TO THEIR ASSOCIATION WITH INTERPERSONAL DOMINANCE (CARNEY ET AL., 2010). THE STUDY TESTED THE NOVEL PREDICTION THAT YOGA POSES, WHICH ARE NOT ASSOCIATED WITH INTERPERSONAL DOMINANCE BUT INCREASE BODILY ENERGY, WOULD INCREASE THE SUBJECTIVE FEELING OF ENERGY AND THEREFORE INCREASE SELF-ESTEEM COMPARED TO 'HIGH POWER' AND 'LOW POWER' POSES. A TWO FACTORIAL, BETWEEN PARTICIPANTS DESIGN WAS EMPLOYED. PARTICIPANTS PERFORMED EITHER TWO STANDING YOGA POSES WITH OPEN FRONT OF THE BODY (N = 19), TWO STANDING YOGA POSES WITH COVERED FRONT OF THE BODY (N = 22), TWO EXPANSIVE, HIGH POWER POSES (N = 21), OR TWO CONSTRICTIVE, LOW POWER POSES (N = 20) FOR 1-MIN EACH. THE RESULTS SHOWED THAT YOGA POSES IN COMPARISON TO 'POWER POSES' INCREASED SELF-ESTEEM. THIS EFFECT WAS MEDIATED BY AN INCREASED SUBJECTIVE SENSE OF ENERGY AND WAS OBSERVED WHEN BASELINE TRAIT SELF-ESTEEM WAS CONTROLLED FOR. THESE RESULTS SUGGEST THAT THE EFFECTS OF PERFORMING OPEN, EXPANSIVE BODY POSTURES MAY BE DRIVEN BY PROCESSES OTHER THAN THE POSES' ASSOCIATION WITH INTERPERSONAL POWER AND DOMINANCE. THIS STUDY DEMONSTRATES THAT POSITIVE EFFECTS OF YOGA PRACTICE CAN OCCUR AFTER PERFORMING YOGA POSES FOR ONLY 2 MIN.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
12  987  24 EFFECTS OF HATHA YOGA EXERCISES ON SPINE FLEXIBILITY IN WOMEN OVER 50 YEARS OLD. [PURPOSE] THE AIM OF THIS STUDY WAS TO ACCESS THE FLEXIBILITY OF THE SPINE IN WOMEN PRACTICING YOGA AS A PART OF THE "UNIVERSITY FOR HEALTH" PROJECT. [SUBJECTS AND METHODS] THE STUDY INCLUDED 56 WOMEN RANGING IN AGE BETWEEN 50-79 AND ATTENDING 90 MINUTES HATHA YOGA SESSIONS ONCE A WEEK. THE MEASUREMENTS WERE PERFORMED TWICE-AT THE BEGINNING OF THE PROJECT AND AFTER ITS COMPLETION, I.E., AFTER 20 WEEKS OF CLASSES. THE RANGE OF SPINE MOBILITY IN THREE PLANES WAS MEASURED USING A RIPPSTEIN PLURIMETER. THE RANGE OF MOTION IN THE SAGITTAL AND FRONTAL PLANES WAS MEASURED IN A STANDING POSITION WITH THE FEET HIP-WIDTH APART. THE TORSIONAL RANGE OF MOTION OF THE SUBJECTS WAS MEASURED WITH THE TRUNK BENT AT A RIGHT ANGLE AND THE LEGS APART. THE FLEXIBILITY RANGES OF THE SPINE AND HAMSTRINGS WERE ALSO MEASURED BY THE TOE-TOUCH TEST IN A STANDING POSITION. [RESULTS] THIS STUDY SHOWED THAT THE APPLIED YOGA EXERCISES INCREASED SPINAL MOBILITY AND FLEXIBILITY OF THE HAMSTRING MUSCLES REGARDLESS OF AGE. [CONCLUSION] YOGA EXERCISES SHOULD BE RECOMMENDED TO THE ELDERLY TO MAKE THEIR MUSCLES MORE FLEXIBLE AND TO INCREASE THE RANGE OF MOTION IN THE JOINTS, WHICH IS PARTICULARLY IMPORTANT FOR IMPROVING THEIR LIFE QUALITY.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
13 1290  25 GROUND REACTION FORCES GENERATED BY TWENTY-EIGHT HATHA YOGA POSTURES. ADHERENTS CLAIM MANY BENEFITS FROM THE PRACTICE OF YOGA, INCLUDING PROMOTION OF BONE HEALTH AND PREVENTION OF OSTEOPOROSIS. HOWEVER, NO KNOWN STUDIES HAVE INVESTIGATED WHETHER YOGA ENHANCES BONE MINERAL DENSITY. FURTHERMORE, NONE HAVE ESTIMATED REACTION FORCES APPLIED BY YOGA PRACTITIONERS. THE PURPOSE OF THIS STUDY WAS TO COLLECT GROUND REACTION FORCE (GRF) DATA ON A VARIETY OF HATHA YOGA POSTURES THAT WOULD COMMONLY BE PRACTICED IN FITNESS CENTERS OR PRIVATE STUDIOS. TWELVE FEMALE AND EIGHT MALE VOLUNTEERS PERFORMED A SEQUENCE OF 28 HATHA YOGA POSTURES WHILE GRF DATA WERE COLLECTED WITH AN AMTI STRAIN-GAUGE FORCE PLATFORM. THE SEQUENCE WAS REPEATED SIX TIMES BY EACH STUDY SUBJECT. FOUR DEPENDENT VARIABLES WERE STUDIED: PEAK VERTICAL GRF, MEAN VERTICAL GRF, PEAK RESULTANT GRF, AND MEAN RESULTANT GRF. UNIVARIATE ANALYSIS WAS USED TO IDENTIFY MEAN VALUES AND STANDARD DEVIATIONS FOR THE DEPENDENT VARIABLES. PEAK VERTICAL AND RESULTANT VALUES OF EACH POSTURE WERE SIMILAR FOR ALL SUBJECTS, AND STANDARD DEVIATIONS WERE SMALL. SIMILARLY, MEAN VERTICAL AND RESULTANT VALUES WERE SIMILAR FOR ALL SUBJECTS. THIS 28 POSTURE YOGA SEQUENCE PRODUCED LOW IMPACT GRF APPLIED TO UPPER AND LOWER EXTREMITIES. FURTHER RESEARCH IS WARRANTED TO DETERMINE WHETHER THESE FORCES ARE SUFFICIENT TO PROMOTE OSTEOGENESIS OR MAINTAIN CURRENT BONE HEALTH IN YOGA PRACTITIONERS.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
14  322  27 ANKLE MOTION IN COMMON YOGA POSES. BACKGROUND: MOTION OF THE ANKLE IS ESSENTIAL FOR MANY YOGA POSES. AN UNDERSTANDING OF RANGE OF ANKLE MOTION DURING TYPICAL YOGA POSES MAY HELP THE CLINICIAN TO UNDERSTAND EXPECTED OUTCOMES OF PATIENTS WHEN RETURNING FROM ANKLE SURGERY OR INJURY TO YOGA. METHODS: THE BIOMECHANICS OF TWENTY HEALTHY ACTIVE YOGIS WERE COLLECTED DURING SEVEN YOGA POSES THAT ARE COMMON WITHIN THEIR PRACTICES. MOTION CAPTURE AND FORCE PLATES WERE USED TO ASSESS THE RANGE OF MOTION AND JOINT MOMENTS OF THE ANKLE FOR EACH POSE. RESULTS: ALL POSES RESULTED IN PLANTARFLEXION AND EXTERNAL ROTATION MOMENTS AT THE ANKLE JOINTS. JOINT LOADING WAS HIGHEST IN SINGLE LEG POSES. THE ARC OF MOTION USED BY THE STUDY PARTICIPANTS IN THE POSES WAS 29 DEGREES OF SAGITTAL MOTION, 20 DEGREES OF FRONTAL MOTION AND 35 DEGREES OF TRANSVERSE MOTION. DISCUSSION: ANKLE MOTION WAS EVALUATED WHEN HEALTHY YOGIS PERFORM STANDARD POSES. THESE RESULTS MAY HELP IN DISCUSSION WITH PATIENTS REGARDING EXPECTED OUTCOMES AFTER ANKLE INJURY OR SURGERY.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
15 2152  22 THE EFFECTS OF SELECTED ASANAS IN IYENGAR YOGA ON FLEXIBILITY: PILOT STUDY. IN RECENT YEARS THE PRACTICE OF YOGA HAS GAINED POPULARITY AS A FORM OF PHYSICAL FITNESS AND EXERCISE, AND HAS BEEN SAID TO IMPROVE STRENGTH AND FLEXIBILITY. THE MAIN OBJECTIVE OF THIS RESEARCH PROJECT WAS TO EVALUATE THE EFFECTS OF A SIX WEEK IYENGAR YOGA INTERVENTION ON FLEXIBILITY. N = 16 LOW TO MODERATELY ACTIVE FEMALES (52.37 +/- 7.79 YEARS) ATTENDED IYENGAR YOGA PRACTICE FOR A TOTAL OF 6 WEEKS, CONSISTING OF ONE 90 MIN SESSION PER WEEK. LUMBAR AND HAMSTRING FLEXIBILITY WERE ASSESSED PRE AND POST-INTERVENTION USING A STANDARD SIT AND REACH TEST. THE RESULTS SHOW A SIGNIFICANT INCREASE IN FLEXIBILITY, INDICATING 6 WEEKS OF SINGLE SESSION YOGA TRAINING MAY BE EFFECTIVE IN INCREASING ERECTOR SPINAE AND HAMSTRING FLEXIBILITY. THIS IS IMPORTANT WHEN CONSIDERING THAT MUCH OF THE POPULATION FIND IT DIFFICULT TO ATTEND MORE THAN ONE SESSION A WEEK INTO THEIR TRAINING SCHEDULE.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
16 2085  27 THE EFFECT OF LONG TERM COMBINED YOGA PRACTICE ON THE BASAL METABOLIC RATE OF HEALTHY ADULTS. BACKGROUND: DIFFERENT PROCEDURES PRACTICED IN YOGA HAVE STIMULATORY OR INHIBITORY EFFECTS ON THE BASAL METABOLIC RATE WHEN STUDIED ACUTELY. IN DAILY LIFE HOWEVER, THESE PROCEDURES ARE USUALLY PRACTICED IN COMBINATION. THE PURPOSE OF THE PRESENT STUDY WAS TO INVESTIGATE THE NET CHANGE IN THE BASAL METABOLIC RATE (BMR) OF INDIVIDUALS ACTIVELY ENGAGING IN A COMBINATION OF YOGA PRACTICES (ASANA OR YOGIC POSTURES, MEDITATION AND PRANAYAMA OR BREATHING EXERCISES) FOR A MINIMUM PERIOD OF SIX MONTHS, AT A RESIDENTIAL YOGA EDUCATION AND RESEARCH CENTER AT BANGALORE. METHODS: THE MEASURED BMR OF INDIVIDUALS PRACTICING YOGA THROUGH A COMBINATION OF PRACTICES WAS COMPARED WITH THAT OF CONTROL SUBJECTS WHO DID NOT PRACTICE YOGA BUT LED SIMILAR LIFESTYLES. RESULTS: THE BMR OF THE YOGA PRACTITIONERS WAS SIGNIFICANTLY LOWER THAN THAT OF THE NON-YOGA GROUP, AND WAS LOWER BY ABOUT 13 % WHEN ADJUSTED FOR BODY WEIGHT (P < 0.001). THIS DIFFERENCE PERSISTED WHEN THE GROUPS WERE STRATIFIED BY GENDER; HOWEVER, THE DIFFERENCE IN BMR ADJUSTED FOR BODY WEIGHT WAS GREATER IN WOMEN THAN MEN (ABOUT 8 AND 18% RESPECTIVELY). IN ADDITION, THE MEAN BMR OF THE YOGA GROUP WAS SIGNIFICANTLY LOWER THAN THEIR PREDICTED VALUES, WHILE THE MEAN BMR OF NON-YOGA GROUP WAS COMPARABLE WITH THEIR PREDICTED VALUES DERIVED FROM 1985 WHO/FAO/UNU PREDICTIVE EQUATIONS. CONCLUSION: THIS STUDY SHOWS THAT THERE IS A SIGNIFICANTLY REDUCED BMR, PROBABLY LINKED TO REDUCED AROUSAL, WITH THE LONG TERM PRACTICE OF YOGA USING A COMBINATION OF STIMULATORY AND INHIBITORY YOGIC PRACTICES.	2006	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
17  404  24 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
18  983  28 EFFECTS OF HATA YOGA ON KNEE OSTEOARTHRITIS. BACKGROUND: THE PURPOSE OF THIS RESEARCH WAS TO STUDY THE EFFECTS OF 8 WEEKS OF HATA YOGA EXERCISES ON WOMEN WITH KNEE OSTEOARTHRITIS. STUDIES ABOUT EFFECTS OF YOGA ON DIFFERENT CHRONIC DISEASES SHOW THAT THESE EXERCISES HAVE POSITIVE EFFECTS ON CHRONIC DISEASES. AS KNEE OSTEOARTHRITIS IS VERY COMMON AMONG MIDDLE AGE WOMEN WE DECIDED TO MEASURE EFFECTIVENESS OF THESE EXERCISES ON KNEE OSTEOARTHRITIS. METHODS: SAMPLE INCLUDED 30 WOMEN WITH KNEE OSTEOARTHRITIS WHO VOLUNTARILY PARTICIPATED IN THIS SEMI-EXPERIMENTAL STUDY AND WERE DIVIDED INTO A CONTROL GROUP (15) AND A YOGA GROUP (15). THE YOGA GROUP RECEIVED 60 MINUTES SESSIONS OF HATA YOGA, 3 TIMES A WEEK AND FOR 8 WEEKS. PAIN, SYMPTOMS, DAILY ACTIVITIES, SPORTS AND SPARE-TIME ACTIVITIES, AND QUALITY OF LIFE WERE RESPECTIVELY MEASURED BY VISUAL ANALOG SCALE (VAS) AND KNEE INJURY AND OSTEOARTHRITIS OUTCOME SCALE (KOOS) QUESTIONNAIRE. THE ANALYSIS OF VARIANCE (ANOVA) METHOD FOR REPETITIVE DATA WAS USED TO ANALYZE THE RESULTS (P = 0.05). RESULTS: FINDINGS SHOWED THAT PAIN AND SYMPTOMS WERE SIGNIFICANTLY DECREASED AND SCORES OF DAILY ACTIVITIES, SPORTS, SPARE-TIME ACTIVITIES, AND QUALITY OF LIFE WERE SIGNIFICANTLY INCREASED IN THE YOGA GROUP. CONCLUSIONS: IT SEEMS THAT YOGA CAN BE USED AS A CONSERVATIVE TREATMENT BESIDES USUAL TREATMENTS AND MEDICATIONS TO IMPROVE THE CONDITION OF PEOPLE WITH OSTEOARTHRITIS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
19 1672  28 NONLINEAR MEASURES IN POSTUROGRAPHY COMPARED TO LINEAR MEASURES BASED ON YOGA POSES PERFORMANCE. PURPOSE: YOGA IS KNOWN AS A TYPE OF EXERCISE THAT COMBINES PHYSICAL, MENTAL AND SPIRITUAL ASPECTS. THERE HAS NOT BEEN MUCH RESEARCH ON THE POSTURAL CONTROL IN VARIOUS YOGA POSES. THE AIM OF THIS STUDY WAS TO EXAMINE COP REGULARITY IN BOTH YOGA INSTRUCTORS AND NOVICES DURING THE PERFORMANCE OF FOUR YOGA POSES, AND TO VERIFY THE SENSITIVITY OF LINEAR AND NONLINEAR METHODS FOR ASSESSING POSTURAL STABILITY. METHODS: THE DYNAMIC CHARACTERISTICS OF COP FLUCTUATIONS WERE EXAMINED USING LINEAR AND NONLINEAR METHODS ON A GROUP OF 22 YOGA INSTRUCTORS (Y) AND 18 AGE-MATCHED NON-PRACTITIONERS OF YOGA (NY). THE STUDY INVOLVED MAINTAINING A BALANCE FOR 20 SECONDS WHILE PERFORMING FOUR YOGA POSES. RESULTS: CONVENTIONAL ANALYSIS OF COP TRAJECTORIES SHOWED THAT NY AND Y EXHIBITED SIMILAR CONTROL OF POSTURAL SWAY, AS INDICATED BY SIMILAR COP PATH-LENGTH AND AREA VALUES OBSERVED IN BOTH GROUPS. THESE RESULTS SUGGEST THAT THE SPECIAL BALANCE YOGA TRAINING RECEIVED BY Y MAY NOT HAVE AN IMPACT ON LESS CHALLENGING BALANCE CONDITIONS, SUCH AS THE POSES USED IN THIS EXPERIMENT. INTERESTINGLY, NONLINEAR DYNAMICAL ANALYSIS OF COP SHOWED THAT Y EXHIBITED LESS COP REGULARITY AND MORE COMPLEX SIGNAL THAN NY, AS EVIDENCED BY HIGHER VALUES OF SAMPLE ENTROPY AND FRACTAL DIMENSION. CONCLUSIONS: THE RESULTS SHED LIGHT ON THE SURPLUS VALUES OF COP TRAJECTORIES IN THE NONLINEAR DYNAMICAL ANALYSIS TO GAIN FURTHER INSIGHT INTO THE MECHANISMS INVOLVED IN POSTURE CONTROL.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
20  341  33 ARTERIAL BLOOD PRESSURE AND CARDIOVASCULAR RESPONSES TO YOGA PRACTICE. CONTEXT: YOGA IS QUALITATIVELY DIFFERENT FROM ANY OTHER MODE OF PHYSICAL ACTIVITY IN THAT IT CONSISTS OF A UNIQUE COMBINATION OF ISOMETRIC MUSCULAR CONTRACTIONS, STRETCHING EXERCISES, RELAXATION TECHNIQUES, AND BREATHING EXERCISES. IN PARTICULAR, YOGA POSTURES CONSIST OF SYSTEMIC ISOMETRIC CONTRACTIONS THAT ARE KNOWN TO ELICIT MARKED INCREASES IN MEAN BLOOD PRESSURE THAT ARE NOT OBSERVED DURING DYNAMIC EXERCISE. STRETCHING CAN ALSO INDUCE INCREASES IN BLOOD PRESSURE AND SYMPATHETIC NERVE ACTIVITY IN THE MUSCLES. CURRENTLY, NOT MUCH IS KNOWN ABOUT CHANGES IN BLOOD PRESSURE AND OTHER CARDIOVASCULAR RESPONSES TO YOGA PRACTICE. OBJECTIVE: THE STUDY INTENDED TO DETERMINE THE ACUTE EFFECTS OF ONE SESSION OF HATHA YOGA PRACTICE ON BLOOD PRESSURE AND OTHER CARDIOVASCULAR RESPONSES. TO GAIN INSIGHT INTO THE LONG-TERM EFFECTS OF YOGA PRACTICE, BOTH NOVICE (N = 19) AND ADVANCED (N = 18) YOGA PRACTITIONERS WERE STUDIED. DESIGN: THE TWO GROUPS WERE MATCHED FOR AGE, GENDER, BMI, AND BLOOD PRESSURE. SETTING: THE SETTING WAS A RESEARCH LABORATORY AT A UNIVERSITY. PARTICIPANTS: THIRTY-SIX APPARENTLY HEALTHY, NONOBESE, SEDENTARY, OR RECREATIONALLY ACTIVE INDIVIDUALS FROM THE COMMUNITY PARTICIPATED IN THE STUDY. INTERVENTION THE INTERVENTION COMPRISED ONE SESSION OF YOGA PRACTICE, IN WHICH PARTICIPANTS FOLLOWED A CUSTOM MADE INSTRUCTIONAL VIDEO PROVIDING A YOGA ROUTINE THAT CONSISTED OF A SERIES OF 23 HATHA-BASED YOGA POSTURES. OUTCOME MEASURES: PRIOR TO ARRIVING AT THE LABORATORY, EACH PARTICIPANT COMPLETED A RESEARCH HEALTH QUESTIONNAIRE, A TRAINING-STATUS QUESTIONNAIRE, AND A YOGA-EXPERIENCE QUESTIONNAIRE. PRIOR TO THE YOGA PRACTICE, EACH PARTICIPANT'S HEIGHT, BODY FAT PERCENTAGE, TRUNK OR LUMBAR FLEXIBILITY, AND ARTERIAL STIFFNESS AS ASSESSED BY CAROTID FEMORAL PULSE WAVE VELOCITY (CFPWV) WERE MEASURED. FOR EACH POSTURE DURING THE YOGA PRACTICE, THE STUDY CONTINUOUSLY MEASURED SYSTOLIC, MEAN, AND DIASTOLIC BLOOD PRESSURES, HEART RATE, STROKE VOLUME, AND CARDIAC OUTPUT. RESULTS: SYSTOLIC, MEAN, AND DIASTOLIC BLOOD PRESSURES INCREASED SIGNIFICANTLY DURING THE YOGA PRACTICE. THE MAGNITUDE OF THESE INCREASES IN BLOOD PRESSURE WAS GREATEST WITH STANDING POSTURES. HEART RATE AND CARDIAC OUTPUT INCREASED SIGNIFICANTLY DURING YOGA PRACTICE, ESPECIALLY WITH STANDING POSTURES. OVERALL, NO DIFFERENCES EXISTED IN CARDIOVASCULAR RESPONSES BETWEEN THE NOVICE AND ADVANCED PRACTITIONERS THROUGHOUT THE YOGA TESTING SESSION; CFPWV VELOCITY WAS SIGNIFICANTLY AND INVERSELY ASSOCIATED WITH LUMBAR FLEXION BUT NOT WITH SIT-AND-REACH TEST SCORES. CONCLUSIONS: THE RESEARCH TEAM CONCLUDED THAT A VARIETY OF HATHA YOGA POSTURES, ESPECIALLY STANDING POSTURES, EVOKED SIGNIFICANT INCREASES IN BLOOD PRESSURE. THE ELEVATION IN BLOOD PRESSURE DUE TO YOGA PRACTICE WAS ASSOCIATED WITH INCREASES IN CARDIAC OUTPUT AND HEART RATE, WHICH ARE RESPONSES SIMILAR TO THOSE OBSERVED IN ISOMETRIC EXERCISE. THE LACK OF OBVIOUS DIFFERENCES IN BLOOD PRESSURE AND OTHER CARDIOVASCULAR RESPONSES BETWEEN NOVICE AND ADVANCED YOGA PRACTITIONERS SUGGESTS THAT LONG-TERM YOGA PRACTICE DOES NOT ATTENUATE ACUTE YOGA RESPONSES.	2013
