1  408 145 BIOMECHANICAL CHARACTERISTICS ON THE LOWER EXTREMITY OF THREE TYPICAL YOGA MANOEUVRES. THIS STUDY WAS AIMED AT EXPLORING THE BIOMECHANICAL CHARACTERISTICS OF THE LOWER EXTREMITY AMONGST THREE TYPICAL YOGA MANOEUVRES. A TOTAL OF THIRTEEN EXPERIENCED FEMALE YOGA PRACTITIONERS WERE RECRUITED IN THE CURRENT STUDY; THEY WERE ALL CERTIFIED WITH THE YOGA ALLIANCE. A THREE-DIMENSIONAL MOTION CAPTURE SYSTEM WITH 10 CAMERAS COMBINED WITH FOUR SYNCHRONISED FORCE PLATES WAS USED TO COLLECT KINEMATICS OF THE LOWER EXTREMITY AND GROUND REACTIVE FORCE WHILST THE PARTICIPANTS PERFORMED THE CRESCENT LUNGE POSE, WARRIOR II POSE, AND TRIANGLE POSE. ONE-WAY REPEATED ANOVA WAS USED IN EXPLORING THE DIFFERENCES AMONGST THE THREE YOGA MOVEMENTS, AND THE SIGNIFICANCE WAS SET TO ALPHA < 0.05. THE TRIANGLE POSE PERFORMED THE LARGEST RANGE OF MOTION (ROM) OF THE HIP (90.5 DEGREES +/- 22.9 DEGREES ), KNEE (68.8 DEGREES +/- 23.1 DEGREES ), AND ANKLE (46.4 DEGREES +/- 11.3 DEGREES ) IN THE SAGITTAL PLANE AND THE HIP (54.8 DEGREES +/- 6.5 DEGREES ), KNEE (42.4 DEGREES +/- 12.8 DEGREES ), AND ANKLE (4.8 DEGREES +/- 1.7 DEGREES ) IN THE FRONTAL PLANE AMONGST THE THREE MANOEUVRES (P < 0.05). NO SIGNIFICANT DIFFERENCE WAS FOUND FOR THE HIP AND ANKLE JOINT MOMENT AMONGST THE THREE MANOEUVRES (P > 0.05). KNEE JOINT TRAVELLED INTO 9.5 DEGREES OF EXTENSION AND SLIGHT ADDUCTION OF 1.94 DEGREES WHILST EXPRESSING THE LARGEST KNEE JOINT ADDUCTION MOMENTS (0.30 +/- 0.22 NM/KG) IN THE TRIANGLE POSE. THE DISTRIBUTION OF THE ANGULAR IMPULSE OF THE LOWER LIMB JOINTS INDICATED THAT THE HIP JOINT CONTRIBUTED SIGNIFICANTLY THE MOST IN THE SAGITTAL AND FRONTAL PLANES OF THE THREE YOGA MANOEUVRES (P < 0.05), RANGING FROM 51.67% TO 70.56%. RESULTS INDICATED THAT TRIANGLE POSE MAY BE SUPERIOR TO THE OTHER TWO MANOEUVRES, WHICH IMPROVED HIP JOINT ROM, STRENGTH, AND DYNAMIC STABILITY. HOWEVER, KNEE INJURIES SUCH AS OSTEOARTHRITIS (OA) SHOULD BE CONSIDERED BECAUSE OF THE LARGE KNEE EXTENSOR ANGLE AND ADDUCTOR MOMENTS.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
2  322  34 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
3 2064  43 THE BIOMECHANICAL DEMANDS OF STANDING YOGA POSES IN SENIORS: THE YOGA EMPOWERS SENIORS STUDY (YESS). BACKGROUND: THE NUMBER OF OLDER ADULTS PARTICIPATING IN YOGA HAS INCREASED DRAMATICALLY IN RECENT YEARS; YET, THE PHYSICAL DEMANDS ASSOCIATED WITH YOGA PERFORMANCE HAVE NOT BEEN REPORTED. THE PRIMARY AIM OF THE YOGA EMPOWERS SENIORS STUDY (YESS) WAS TO USE BIOMECHANICAL METHODS TO QUANTIFY THE PHYSICAL DEMANDS ASSOCIATED WITH THE PERFORMANCE OF 7 COMMONLY-PRACTICED STANDING YOGA POSES IN OLDER ADULTS. METHODS: 20 AMBULATORY OLDER ADULTS (70.7+-3.8 YRS) ATTENDED 2 WEEKLY 60-MINUTE HATHA YOGA CLASSES FOR 32 WEEKS. THE LOWER-EXTREMITY NET JOINT MOMENTS OF FORCE (JMOFS), WERE OBTAINED DURING THE PERFORMANCE OF THE FOLLOWING POSES: CHAIR, WALL PLANK, TREE, WARRIOR II, SIDE STRETCH, CRESCENT, AND ONE-LEGGED BALANCE. REPEATED-MEASURE ANOVA AND TUKEY'S POST-HOC TESTS WERE USED TO IDENTIFY DIFFERENCES IN JMOFS AMONG THE POSES. ELECTROMYOGRAPHIC ANALYSIS WAS USED TO SUPPORT THE JMOF FINDINGS. RESULTS: THERE WAS A SIGNIFICANT MAIN EFFECT FOR POSE, AT THE ANKLE, KNEE AND HIP, IN THE FRONTAL AND SAGITTAL PLANES (P=0.00-0.03). THE CRESCENT, CHAIR, WARRIOR II, AND ONE-LEGGED BALANCE POSES GENERATED THE GREATEST AVERAGE SUPPORT MOMENTS. SIDE STRETCH GENERATED THE GREATEST AVERAGE HIP EXTENSOR AND KNEE FLEXOR JMOFS. CRESCENT PLACED THE HIGHEST DEMANDS ON THE HIP FLEXORS AND KNEE EXTENSORS. ALL OF THE POSES PRODUCED ANKLE PLANTAR-FLEXOR JMOFS. IN THE FRONTAL PLANE, THE TREE GENERATED THE GREATEST AVERAGE HIP AND KNEE ABDUCTOR JMOFS; WHEREAS WARRIOR II GENERATED THE GREATEST AVERAGE HIP AND KNEE ADDUCTOR JMOFS. WARRIOR II AND ONE-LEGGED BALANCE INDUCED THE LARGEST AVERAGE ANKLE EVERTOR AND INVERTOR JMOFS, RESPECTIVELY. THE ELECTROMYOGRAPHIC FINDINGS WERE CONSISTENT WITH THE JMOF RESULTS. CONCLUSIONS: MUSCULOSKELETAL DEMAND VARIED SIGNIFICANTLY ACROSS THE DIFFERENT POSES. THESE FINDINGS MAY BE USED TO GUIDE THE DESIGN OF EVIDENCE-BASED YOGA INTERVENTIONS THAT ADDRESS INDIVIDUAL-SPECIFIC TRAINING AND REHABILITATION GOALS IN SENIORS.

4 2306  45 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
5 2357  38 VARYING ALIGNMENT AFFECTS LOWER EXTREMITY JOINT AND LIMB LOADING DURING YOGA'S TRIANGLE (TRIKONASANA) POSE. BACKGROUND: LIMITED BIOMECHANICAL DATA EXIST DESCRIBING HOW YOGA ASANAS (POSTURES) LOAD THE LIMBS AND JOINTS, AND LITTLE EVIDENCE-BASED RECOMMENDATIONS FOR YOGA INJURY PREVENTION ARE AVAILABLE. THIS STUDY AIMED TO ESTABLISH JOINT LOADING METRICS FOR AN INJURY-PRONE, YET COMMON YOGA POSE, THE TRIANGLE ASANA (TRIKONASANA) BY IDENTIFYING HOW STANCE WIDTH ADJUSTMENTS ALTER LOWER EXTREMITY LOADING. METHODS: EIGHTEEN YOGA PRACTITIONERS UNDERWENT 3D MOTION ANALYSIS WHILE PERFORMING TRIKONASANA WITH SELF-SELECTED (SS) STANCE WIDTH AND -30, -20, -10, +10, +20, AND +30% OF SS STANCE WIDTH. GROUND REACTION FORCES (GRFS), JOINT FORCES, AND JOINT MOMENTS WERE CALCULATED FOR THE LEADING AND TRAILING LIMB ANKLE, KNEE, AND HIP. ONE-WAY REPEATED-MEASURES ANALYSIS OF VARIANCE DETERMINED DIFFERENCES IN LOADING DUE TO STANCE WIDTH. RESULTS: GRFS, NET JOINT FORCES, AND NET JOINT MOMENTS WERE SIGNIFICANTLY AFFECTED BY STANCE WIDTH WHERE INCREASING STANCE WIDTH INCREASED LEADING LIMB LOADING BUT DECREASED TRAILING LIMB LOADING. CONCLUSIONS: ALTERING STANCE WIDTH OF TRIKONASANA INFLUENCES LOWER EXTREMITY LIMB LOADING, AND THESE LOADING RESPONSES WERE LIMB-DEPENDENT. YOGA PRACTITIONERS AND INSTRUCTORS CAN USE THIS INFORMATION TO OBJECTIVELY SUPPORT INCREASING OR DECREASING STANCE WIDTH TO REDUCE OR INCREASE LIMB LOADING ACCORDING TO THEIR GOALS OR TO MAKE ACCOMMODATIONS TO GROUPS SUCH AS BEGINNERS OR AT-RISK POPULATIONS FOR SAFER, MORE ACCESSIBLE YOGA PRACTICES. CUING A WIDER OR NARROWER STANCE WIDTH WILL NOT HAVE THE SAME EFFECT ON BOTH LIMBS.	2022

7 2100  32 THE EFFECT OF YOGA ON ARM VOLUME, STRENGTH, AND RANGE OF MOTION IN WOMEN AT RISK FOR BREAST CANCER-RELATED LYMPHEDEMA. OBJECTIVES: TO ASSESS THE FEASIBILITY, SAFETY, AND INITIAL ESTIMATES OF EFFICACY OF A YOGA PROGRAM IN POSTOPERATIVE CARE FOR WOMEN AT HIGH RISK FOR BREAST CANCER-RELATED LYMPHEDEMA (BCRL). DESIGN: SINGLE-GROUP PRETEST-POST-TEST DESIGN. SETTINGS/LOCATION: PATIENTS WERE RECRUITED FROM THE UNIVERSITY OF CALIFORNIA, SAN FRANCISCO CAROL FRANC BUCK BREAST CARE CENTER. SUBJECTS: TWENTY-ONE WOMEN WERE ENROLLED IN THE STUDY. WOMEN WERE >18 YEARS OF AGE, HAD UNDERGONE SURGICAL TREATMENT FOR BREAST CANCER, AND WERE AT HIGH RISK FOR BCRL. INTERVENTION: THE WOMEN PARTICIPATED IN AN ASHTANGA YOGA INTERVENTION FOR 8 WEEKS. SESSIONS CONSISTED OF ONCE/WEEK INSTRUCTOR-LED PRACTICE AND ONCE/WEEK HOME PRACTICE. PARTICULAR ATTENTION WAS GIVEN TO POSES THAT EMPHASIZED UPPER BODY STRENGTH AND FLEXIBILITY, WHILE AVOIDING SIGNIFICANT TIME WITH THE UPPER EXTREMITY (UE) IN A DEPENDENT POSITION. OUTCOME MEASURES: UE VOLUME WAS ASSESSED THROUGH CIRCUMFERENTIAL FOREARM MEASUREMENT, WHICH WAS CONVERTED TO VOLUME USING THE FORMULA FOR A TRUNCATED CONE. RANGE OF MOTION (ROM) WAS ASSESSED FOR THE SHOULDERS, ELBOWS, AND WRISTS, USING A STANDARD GONIOMETER. UE STRENGTH WAS ASSESSED FOR SHOULDER ABDUCTION, ELBOW FLEXION, WRIST FLEXION, AND GRIP USING A DYNAMOMETER. RESULTS: TWENTY WOMEN COMPLETED THE YOGA INTERVENTION, WITH 17 RETURNING FOR FINAL ASSESSMENT. MEAN AGE WAS 52 (+/-9.1) YEARS AND BODY MASS INDEX WAS 24.8 (+/-5.1) KG/M(2). POSTINTERVENTION, MEAN VOLUME IN THE AT-RISK UE WAS SLIGHTLY REDUCED (P = 0.397). ROM FOR SHOULDER FLEXION (P < 0.01) AND EXTERNAL ROTATION (P < 0.05) SIGNIFICANTLY INCREASED BILATERALLY. SHOULDER ABDUCTION ROM SIGNIFICANTLY IMPROVED FOR THE UNAFFECTED LIMB (P = 0.001). FOLLOWING INTERVENTION, STRENGTH IMPROVED ON THE AFFECTED SIDE FOR SHOULDER ABDUCTION AND GRIP STRENGTH, AND BILATERALLY FOR ELBOW FLEXION (P < 0.05 FOR ALL). CONCLUSIONS: THESE PRELIMINARY FINDINGS SUGGEST THAT YOGA IS FEASIBLE AND SAFE FOR WOMEN WHO ARE AT RISK FOR BCRL AND MAY RESULT IN SMALL IMPROVEMENTS IN SHOULDER ROM AND UE STRENGTH.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
8 1269  28 FRAILTY MODIFIES THE INTERVENTION EFFECT OF CHAIR YOGA ON PAIN AMONG OLDER ADULTS WITH LOWER EXTREMITY OSTEOARTHRITIS: SECONDARY ANALYSIS OF A NONPHARMACOLOGICAL INTERVENTION TRIAL. OBJECTIVE: IN AN 8-WEEK NONPHARMACOLOGICAL PAIN INTERVENTION TRIAL AMONG OLDER ADULTS WITH LOWER EXTREMITY OSTEOARTHRITIS (OA), WE AIMED TO EXAMINE: A) THE BASELINE FRAILTY LEVEL OF THE PARTICIPANTS; B) WHETHER SUCH INTERVENTION IS MORE BENEFICIAL FOR BASELINE FRAILER OLDER ADULTS THAN FOR THEIR COUNTERPARTS WITH LESS FRAILTY; AND C) WHETHER THE INTERVENTION COULD ALSO ALTER FRAILTY. METHODS: PARTICIPANTS WERE RANDOMLY ASSIGNED TO EITHER CHAIR YOGA (CY) OR HEALTH EDUCATION PROGRAM (HEP) GROUPS AND ATTENDED TWICE-WEEKLY 45-MINUTE CY OR HEP SESSIONS FOR 8 WEEKS. FOLLOWING A STANDARD PROCEDURE, 82 VARIABLES WERE USED TO CONSTRUCT A FRAILTY INDEX (FI, 0-1). PRIMARY OUTCOMES WERE: WESTERN ONTARIO AND MCMASTER UNIVERSITIES (WOMAC) PAIN AND PAIN INTERFERENCE. LINEAR MIXED-EFFECTS MODELS WERE USED TO EVALUATE THE MODIFYING EFFECT OF BASELINE FRAILTY ON THE INTERVENTION EFFECT OF CY ON PRIMARY OUTCOMES. SIMILAR MODELS WERE USED TO EVALUATE THE EFFECT OF CY ON FRAILTY. RESULTS: A TOTAL OF 112 PARTICIPANTS (N = 63 CY, N = 49 HEP; 75.3 [SD = 7.5] YEARS) WITH 85 FEMALES (75.9%) WERE INCLUDED. THE MEAN VALUES OF BASELINE FI FOR THE CY AND HEP GROUPS WERE SIMILAR (0.428 [0.05] AND 0.433 [0.05], P = 0.355). EACH 0.01 INCREMENT IN BASELINE FI WAS ASSOCIATED WITH HIGHER WOMAC PAIN (BETA = 0.28, P < 0.001) AND PAIN INTERFERENCE (BETA = 0.51, P < 0.001). THERE WAS A SIGNIFICANT INTERACTION EFFECT BETWEEN INTERVENTION, TIME, AND BASELINE FI (P = 0.020 FOR WOMAC PAIN; P = 0.010 FOR PAIN INTERFERENCE), INDICATING THAT PARTICIPANTS WITH HIGHER LEVEL OF BASELINE FI HAD GREATER DECLINES IN WOMAC PAIN AND PAIN INTERFERENCE. THERE WAS NO SIGNIFICANTLY GREATER DECLINE IN FI FOR THE CY GROUP COMPARED TO THE HEP GROUP (BETWEEN-GROUP DIFFERENCE - 0.01; P = 0.509) AND THERE WERE NO SIGNIFICANT TREND CHANGES IN FI (P FOR INTERACTION = 0.605). CONCLUSIONS: FRAILTY MODIFIES THE INTERVENTION EFFECT OF CY ON PAIN AMONG OLDER ADULTS WITH LOWER EXTREMITY OA, UNDERSCORING THE IMPORTANCE OF ASSESSING FRAILTY TO IMPROVE THE MANAGEMENT OF PAIN IN THIS POPULATION.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
9 1348  31 IDENTIFYING YOGA-BASED KNEE STRENGTHENING EXERCISES USING THE KNEE ADDUCTION MOMENT. BACKGROUND: THIS STUDY AIMED TO COMPARE MUSCLE ACTIVATIONS, CO-CONTRACTION INDICES, AND THE KNEE ADDUCTION MOMENT BETWEEN STATIC STANDING YOGA POSTURES TO IDENTIFY APPROPRIATE EXERCISES FOR KNEE OSTEOARTHRITIS. METHODS: HEALTHY YOUNG WOMEN (24.4 (5.4) YEARS, 23.1 (3.7) KG/M(2)) PARTICIPATED. PRIMARY OUTCOME VARIABLES WERE ELECTROMYOGRAPHIC ACTIVATIONS OF THE VASTUS LATERALIS, RECTUS FEMORIS, VASTUS MEDIALIS, BICEPS FEMORIS, AND SEMITENDINOSUS; CO-CONTRACTION BETWEEN THE BICEPS FEMORIS AND RECTUS FEMORIS, AND VASTUS LATERALIS AND VASTUS MEDIALIS; AND KNEE ADDUCTION MOMENTS OF BOTH LEGS DURING SIX STATIC, STANDING YOGA POSTURES (TWO SQUATTING POSTURES, TWO LUNGING POSTURES, A HAMSTRING STRETCH, AND A SINGLE-LEG BALANCE POSTURE). A TWO-FACTOR REPEATED MEASURES ANALYSIS OF VARIANCE WAS USED TO IDENTIFY DIFFERENCES IN MUSCLE AMPLITUDES, CO-CONTRACTIONS, AND KNEE ADDUCTION MOMENT BETWEEN POSTURES AND LEGS. FINDINGS: QUADRICEPS ACTIVATIONS WERE HIGHEST DURING SQUAT AND LUNGE POSTURES (P</=0.001). HAMSTRING ACTIVATIONS WERE HIGHEST DURING THE HAMSTRING STRETCH (P</=0.003). SQUAT AND LUNGE POSTURES PRODUCED HIGHER CO-CONTRACTION INDICES THAN OTHER POSTURES (P</=0.011). THE WIDE LEGGED SQUAT (GODDESS) AND LUNGE WITH TRUNK UPRIGHT (WARRIOR) PRODUCED THE LOWEST KNEE ADDUCTION MOMENTS (P</=0.006), WHILE THE SINGLE-LEG BALANCE POSTURE ELICITED A HIGHER KNEE ADDUCTION MOMENT THAN ALL OTHER POSTURES (P<0.05). INTERPRETATION: SQUATTING AND LUNGING POSTURES COULD IMPROVE LEG STRENGTH WHILE POTENTIALLY MINIMIZING EXPOSURE TO HIGH KNEE ADDUCTION MOMENTS. FUTURE WORK SHOULD EVALUATE WHETHER THESE EXERCISES ARE USEFUL IN PEOPLE WITH KNEE OSTEOARTHRITIS.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
10 1047  25 EFFECTS OF YOGA ON ARM VOLUME AMONG WOMEN WITH BREAST CANCER RELATED LYMPHEDEMA: A PILOT STUDY. LYMPHEDEMA AFFECTS 3-58% OF SURVIVORS OF BREAST CANCER AND CAN RESULT IN UPPER EXTREMITY IMPAIRMENTS. EXERCISE CAN BE BENEFICIAL IN MANAGING LYMPHEDEMA. YOGA PRACTICE HAS BEEN MINIMALLY STUDIED FOR ITS EFFECTS ON BREAST CANCER RELATED LYMPHEDEMA (BCRL). THE PURPOSE OF THIS STUDY WAS TO DETERMINE THE EFFECT OF YOGA ON ARM VOLUME, QUALITY OF LIFE (QOL), SELF-REPORTED ARM FUNCTION, AND HAND GRIP STRENGTH IN WOMEN WITH BCRL. SIX WOMEN WITH BCRL PARTICIPATED IN MODIFIED HATHA YOGA 3X/WEEK FOR 8 WEEKS. COMPRESSION SLEEVES WERE WORN DURING YOGA SESSIONS. ARM VOLUME, QOL, SELF-REPORTED ARM FUNCTION, AND HAND GRIP STRENGTH WERE MEASURED AT BASELINE, HALF-WAY, AND AT THE CONCLUSION OF YOGA PRACTICE. ARM VOLUME SIGNIFICANTLY DECREASED FROM BASELINE (2423.3 ML +/- 597.2) TO FINAL MEASURES (2370.8 ML +/- 577.2) (P = .02). NO SIGNIFICANT CHANGES IN QOL (P = .12), SELF-REPORTED ARM FUNCTION (P = .34), OR HAND GRIP STRENGTH (P = .26) WERE FOUND. YOGA MAY BE BENEFICIAL IN THE MANAGEMENT OF LYMPHEDEMA.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
11 2712  28 YOGA LEADS TO MULTIPLE PHYSICAL IMPROVEMENTS AFTER STROKE, A PILOT STUDY. OBJECTIVE: TO ASSESS CHANGE IN PHYSICAL FUNCTIONING (PAIN, RANGE OF MOTION (ROM), STRENGTH, AND ENDURANCE) AFTER 8 WEEKS OF THERAPEUTIC-YOGA. DESIGN: PLANNED ANALYSES OF DATA FROM A RANDOMIZED PILOT STUDY OF YOGA AFTER STROKE. SETTING: UNIVERSITY-BASED RESEARCH LABORATORY. PARTICIPANTS: PEOPLE WITH CHRONIC STROKE (N=47) RANDOMIZED TO THERAPEUTIC-YOGA (N=37) OR WAIT-LIST CONTROL (N=10). INTERVENTIONS: 16 SESSIONS OF THERAPEUTIC YOGA (TWICE A WEEK/8 WEEKS). YOGA WAS DELIVERED IN A STANDARDIZED AND PROGRESSIVE FORMAT WITH POSTURES, BREATHING, AND MEDITATION, AND RELAXATION IN SITTING, STANDING, AND SUPINE. MAIN MEASURES: PAIN WAS ASSESSED WITH THE PEG, A 3-ITEM FUNCTIONAL MEASURE OF THE INTERFERENCE OF PAIN. ROM INCLUDED NECK AND HIP ACTIVE AND PASSIVE ROM MEASUREMENTS). UPPER AND LOWER EXTREMITY STRENGTH WERE ASSESSED WITH THE ARM CURL TEST AND CHAIR-TO-STAND TEST, RESPECTIVELY. ENDURANCE WAS ASSESSED WITH THE 6-MINUTE WALK AND MODIFIED 2-MIN STEP TEST. RESULTS: AFTER A BONFERRONI CORRECTION, PAIN, NECK ROM, HIP PASSIVE ROM, UPPER EXTREMITY STRENGTH, AND THE 6-MIN WALK SCORES ALL SIGNIFICANTLY IMPROVED AFTER 8 WEEKS OF ENGAGING IN YOGA. NO CHANGES OCCURRED IN THE WAIT-LIST CONTROL GROUP. CONCLUSIONS: A GROUP THERAPEUTIC-YOGA INTERVENTION MAY IMPROVE MULTIPLE ASPECTS OF PHYSICAL FUNCTIONING AFTER STROKE. SUCH AN INTERVENTION MAY BE COMPLEMENTARY TO TRADITIONAL REHABILITATION.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
12   58  28 A COMPARISON OF EMG OUTPUT OF FOUR LOWER EXTREMITY MUSCLES DURING SELECTED YOGA POSTURES. THE PURPOSE OF THIS STUDY WAS TO USE SURFACE ELECTROMYOGRAPHY (EMG) ANALYSIS TO EXAMINE THE MUSCLE ACTIVATION OF THE ANTERIOR TIBIALIS (TA), GASTROCNEMIUS (GA), RECTUS FEMORIS (RF) AND BICEPS FEMORIS (BF) MUSCLES DURING SEVERAL YOGA POSES: TREE POSE (VRKSASHANA), HALF MOON POSE (ARDHA CHANDRASANA) AND WARRIOR III (VIRABADRASANA) WHEN COMPARED TO A REST POSE (MOUNTAIN POSE). TEN HEALTHY FEMALES WITH MORE THAN 3 MONTHS OF CONTINUOUS YOGA EXPERIENCE WHO PRACTICED AT LEAST 1.5H PER WEEK WERE RECRUITED. EMG ACTIVITY WAS RECORDED FROM THE AFOREMENTIONED MUSCLES DURING MOUNTAIN POSE ("REST") FOR 30S, THREE TIMES. SUBJECTS THEN PERFORMED THE FOLLOWING YOGA POSES IN A RANDOMIZED SEQUENCE WHILE SURFACE EMG ACTIVITY WAS RECORDED: TREE POSE, HALF-MOON, AND WARRIOR III. EACH POSE WAS HELD FOR 20S TO 30S AND PERFORMED THREE TIMES. EMG DATA WERE BAND PASS FILTERED AND THE ROOT MEAN SQUARE (RMS) WAS OBTAINED. THE PEAK RMS OF EACH OF THE RESTING TRIALS WAS OBTAINED AND AVERAGED TO PRODUCE AN AVERAGE PEAK RESTING RMS VALUE. THE STUDY REVEALED SIGNIFICANTLY GREATER EMG ACTIVITY IN TA AND GA IN ALL THREE POSES WHEN COMPARED TO BF AND RF. BF PRODUCED GREATER EMG ACTIVITY THAN RF IN WARRIOR III. IN CONCLUSION, SINGLE LIMB YOGA POSES REQUIRE INCREASED USE OF THE ANKLE MUSCULATURE WHEN COMPARED TO THIGH MUSCULATURE.	2019

UNDERSTANDING THE PHYSICAL DEMANDS PLACED UPON THE MUSCULOSKELETAL SYSTEM BY INDIVIDUAL POSTURES MAY ALLOW EXPERIENCED INSTRUCTORS AND THERAPISTS TO DEVELOP SAFE AND EFFECTIVE YOGA PROGRAMS WHICH REDUCE UNDESIRABLE SIDE EFFECTS. 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
14  107  25 A PILOT RANDOMIZED CONTROLLED TRIAL OF THE EFFECTS OF CHAIR YOGA ON PAIN AND PHYSICAL FUNCTION AMONG COMMUNITY-DWELLING OLDER ADULTS WITH LOWER EXTREMITY OSTEOARTHRITIS. OBJECTIVES: TO DETERMINE EFFECTS OF SIT 'N' FIT CHAIR YOGA, COMPARED TO A HEALTH EDUCATION PROGRAM (HEP), ON PAIN AND PHYSICAL FUNCTION IN OLDER ADULTS WITH LOWER EXTREMITY OSTEOARTHRITIS (OA) WHO COULD NOT PARTICIPATE IN STANDING EXERCISE. DESIGN: TWO-ARM RANDOMIZED CONTROLLED TRIAL. SETTING: ONE HUD SENIOR HOUSING FACILITY AND ONE DAY SENIOR CENTER IN SOUTH FLORIDA. PARTICIPANTS: COMMUNITY-DWELLING OLDER ADULTS (N = 131) WERE RANDOMLY ASSIGNED TO CHAIR YOGA (N = 66) OR HEP (N = 65). THIRTEEN DROPPED AFTER ASSIGNMENT BUT PRIOR TO THE INTERVENTION; SIX DROPPED DURING THE INTERVENTION; 106 OF 112 COMPLETED AT LEAST 12 OF 16 SESSIONS (95% RETENTION RATE). INTERVENTIONS: PARTICIPANTS ATTENDED EITHER CHAIR YOGA OR HEP. BOTH INTERVENTIONS CONSISTED OF TWICE-WEEKLY 45-MINUTE SESSIONS FOR 8 WEEKS. MEASUREMENTS: PRIMARY: PAIN, PAIN INTERFERENCE; SECONDARY: BALANCE, GAIT SPEED, FATIGUE, FUNCTIONAL ABILITY MEASURED AT BASELINE, AFTER 4 WEEKS OF INTERVENTION, AT THE END OF THE 8-WEEK INTERVENTION, AND POST-INTERVENTION (1 AND 3 MONTHS). RESULTS: THE CHAIR YOGA GROUP SHOWED GREATER REDUCTION IN PAIN INTERFERENCE DURING THE INTERVENTION (P = .01), SUSTAINED THROUGH 3 MONTHS (P = .022). WOMAC PAIN (P = .048), GAIT SPEED (P = .024), AND FATIGUE (P = .037) WERE IMPROVED IN THE YOGA GROUP DURING THE INTERVENTION (P = .048) BUT IMPROVEMENTS WERE NOT SUSTAINED POST INTERVENTION. CHAIR YOGA HAD NO EFFECT ON BALANCE. CONCLUSION: AN 8-WEEK CHAIR YOGA PROGRAM WAS ASSOCIATED WITH REDUCTION IN PAIN, PAIN INTERFERENCE, AND FATIGUE, AND IMPROVEMENT IN GAIT SPEED, BUT ONLY THE EFFECTS ON PAIN INTERFERENCE WERE SUSTAINED 3 MONTHS POST INTERVENTION. CHAIR YOGA SHOULD BE FURTHER EXPLORED AS A NONPHARMACOLOGIC INTERVENTION FOR OLDER PEOPLE WITH OA IN THE LOWER EXTREMITIES.

15  896  31 EFFECT OF YOGASANA INTERVENTION ON STANDING BALANCE PERFORMANCE AMONG PEOPLE WITH DIABETIC PERIPHERAL NEUROPATHY: A PILOT STUDY. BACKGROUND: DIABETIC PERIPHERAL NEUROPATHY (DPN) IS KNOWN TO CAUSE IMPAIRED BALANCE AND EVENTUALLY INCREASED RISK OF FALL. YOGASANAS CHARACTERIZED BY SLOW, GENTLE TRANSITIONS INTO POSTURES WITH A VARYING BASE OF SUPPORT AND FOCUS ON BODY AWARENESS DURING MOVEMENT HOLD POTENTIAL FOR TRAINING BALANCE CONTROL. THEREFORE, THE CURRENT STUDY AIMED TO EVALUATE EFFECT OF STRUCTURED YOGASANA INTERVENTION COMPARED TO CONVENTIONAL BALANCE EXERCISE ON STATIC AND DYNAMIC BALANCE PERFORMANCE AMONG PEOPLE WITH DIABETIC NEUROPATHY. METHODS: : THIRTY-FIVE PEOPLE WITH DPN AGED 42-70 YEARS WERE RECRUITED TO YOGASANA INTERVENTION GROUP (N = 11), CONVENTIONAL BALANCE EXERCISES GROUP (N = 10), AND CONTROL GROUP (N = 14) FOLLOWING ETHICAL APPROVAL. ALL PARTICIPANTS WERE EVALUATED AT BASELINE AND POST 12-WEEK INTERVENTION ON STAR EXCURSION BALANCE TEST, SINGLE-LIMB STANCE TEST, AND CENTER OF PRESSURE (COP) EXCURSION FOR BALANCE PERFORMANCE, MODIFIED FALL EFFICACY SCALE FOR FEAR OF FALLS AND LOWER EXTREMITY STRENGTH USING CHAIR STAND TEST AND STEP-UP TEST. RESULTS: BALANCE PERFORMANCE (STATIC AND DYNAMIC MEASURED BY STAR EXCURSION BALANCE TEST, SINGLE-LIMB STANCE TEST, AND COP EXCURSION, LOWER EXTREMITY STRENGTH (USING CHAIR STAND TEST AND STEP-UP TEST) DEMONSTRATED IMPROVEMENT AND FEAR OF FALL REDUCED AMONG YOGASANA INTERVENTION GROUP (P = 0.05) AND CONVENTIONAL BALANCE EXERCISES GROUP (P = 0.05) POST 12-WEEK INTERVENTION. COP EXCURSION INCREASED IN THE CONTROL GROUP INDICATING DETERIORATION IN BALANCE PERFORMANCE AFTER 12 WEEKS (P = 0.05). POST HOC COMPARISON REVEALED THAT YOGASANA INTERVENTION WAS MARGINALLY MORE EFFECTIVE IN IMPROVING STATIC AND DYNAMIC BALANCE PERFORMANCE COMPARED TO CONVENTIONAL BALANCE EXERCISES IN ALL VARIABLES OF STANDING BALANCE PERFORMANCE (P = 0.025). CONCLUSION: YOGASANA AND CONVENTIONAL BALANCE EXERCISES WERE EFFECTIVE IN IMPROVING STATIC AND DYNAMIC BALANCE PERFORMANCE, LOWER EXTREMITY MUSCLE STRENGTH, AND REDUCING FEAR OF FALL AMONG PEOPLE WITH DPN. YOGASANA INTERVENTION DEMONSTRATED MARGINALLY GREATER IMPROVEMENT IN STATIC AND DYNAMIC BALANCE PERFORMANCE AND LOWER EXTREMITY MUSCLE STRENGTH COMPARED TO CONVENTIONAL EXERCISE.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
16  253  40 A YOGA STRENGTHENING PROGRAM DESIGNED TO MINIMIZE THE KNEE ADDUCTION MOMENT FOR WOMEN WITH KNEE OSTEOARTHRITIS: A PROOF-OF-PRINCIPLE COHORT STUDY. UNLABELLED: PEOPLE WITH KNEE OSTEOARTHRITIS MAY BENEFIT FROM EXERCISE PRESCRIPTIONS THAT MINIMIZE KNEE LOADS IN THE FRONTAL PLANE. THE PRIMARY OBJECTIVE OF THIS STUDY WAS TO DETERMINE WHETHER A NOVEL 12-WEEK STRENGTHENING PROGRAM DESIGNED TO MINIMIZE EXPOSURE TO THE KNEE ADDUCTION MOMENT (KAM) COULD IMPROVE SYMPTOMS AND KNEE STRENGTH IN WOMEN WITH SYMPTOMATIC KNEE OSTEOARTHRITIS. A SECONDARY OBJECTIVE WAS TO DETERMINE WHETHER THE PROGRAM COULD IMPROVE MOBILITY AND FITNESS, AND DECREASE PEAK KAM DURING GAIT. THE TERTIARY OBJECTIVE WAS TO EVALUATE THE BIOMECHANICAL CHARACTERISTICS OF THIS YOGA PROGRAM. IN PARTICULAR, WE COMPARED THE PEAK KAM DURING GAIT WITH THAT DURING YOGA POSTURES AT BASELINE. WE ALSO COMPARED LOWER LIMB NORMALIZED MEAN ELECTROMYOGRAPHY (EMG) AMPLITUDES DURING YOGA POSTURES BETWEEN BASELINE AND FOLLOW-UP. PRIMARY MEASURES INCLUDED SELF-REPORTED PAIN AND PHYSICAL FUNCTION (KNEE INJURY AND OSTEOARTHRITIS OUTCOME SCORE) AND KNEE STRENGTH (EXTENSOR AND FLEXOR TORQUES). SECONDARY MEASURES INCLUDED MOBILITY (SIX-MINUTE WALK, 30-SECOND CHAIR STAND, STAIR CLIMBING), FITNESS (SUBMAXIMAL CYCLE ERGOMETER TEST), AND CLINICAL GAIT ANALYSIS USING MOTION CAPTURE SYNCHRONIZED WITH ELECTROMYOGRAPHY AND FORCE MEASUREMENT. ALSO, KAM AND NORMALIZED MEAN EMG AMPLITUDES WERE COLLECTED DURING YOGA POSTURES. FORTY-FIVE WOMEN OVER AGE 50 WITH SYMPTOMATIC KNEE OSTEOARTHRITIS, CONSISTENT WITH THE AMERICAN COLLEGE OF RHEUMATOLOGY CRITERIA, ENROLLED IN OUR 12-WEEK (3 SESSIONS PER WEEK) PROGRAM. DATA FROM 38 WERE ANALYZED (SIX DROP-OUTS; ONE LOST TO CO-INTERVENTION). PARTICIPANTS EXPERIENCED REDUCED PAIN (MEAN IMPROVEMENT 10.1-20.1 NORMALIZED TO 100; P<0.001), INCREASED KNEE EXTENSOR STRENGTH (MEAN IMPROVEMENT 0.01 NM/KG; P = 0.004), AND INCREASED FLEXOR STRENGTH (MEAN IMPROVEMENT 0.01 NM/KG; P = 0.001) AT FOLLOW-UP COMPARED TO BASELINE. PARTICIPANTS IMPROVED MOBILITY ON THE SIX-MINUTE WALK (MEAN IMPROVEMENT 37.7 M; P<0.001) AND 30-SECOND CHAIR STAND (MEAN IMPROVEMENT 1.3; P = 0.006) AT FOLLOW-UP COMPARED TO BASELINE. FITNESS AND PEAK KAM DURING GAIT WERE UNCHANGED BETWEEN BASELINE AND FOLLOW-UP. AVERAGE KAM DURING THE YOGA POSTURES WERE LOWER THAN THAT OF NORMAL GAIT. NORMALIZED MEAN EMG AMPLITUDES DURING YOGA POSTURES WERE UP TO 31.0% OF MAXIMUM BUT DID NOT CHANGE BETWEEN BASELINE AND FOLLOW-UP. IN THIS COHORT STUDY, THE YOGA-BASED STRENGTHENING POSTURES THAT ELICIT LOW KAMS IMPROVED KNEE SYMPTOMS AND STRENGTH IN WOMEN WITH KNEE OA FOLLOWING A 12 WEEK PROGRAM (3 SESSIONS PER WEEK). THE PROGRAM ALSO IMPROVED MOBILITY, BUT DID NOT IMPROVE FITNESS OR REDUCE PEAK KAM DURING GAIT. THE KAM DURING THE YOGA POSTURES WERE LOWER THAN THAT OF NORMAL GAIT. OVERALL, THE PROPOSED PROGRAM MAY BE USEFUL IN IMPROVING PAIN, STRENGTH, AND MOBILITY IN WOMEN WITH KNEE OSTEOARTHRITIS. CLINICAL EFFICACY NEEDS TO BE ASSESSED USING A RANDOMIZED CONTROLLED TRIAL DESIGN. TRIAL REGISTRATION: CLINICALTRIALS.GOV NCT02146105.	2015	

17 2193  29 THE EFFECTS OF YOGA TRAINING AND A SINGLE BOUT OF YOGA ON DELAYED ONSET MUSCLE SORENESS IN THE LOWER EXTREMITY. THE PURPOSE OF THIS STUDY WAS TO DETERMINE THE EFFECTS OF YOGA TRAINING AND A SINGLE BOUT OF YOGA ON THE INTENSITY OF DELAYED ONSET MUSCLE SORENESS (DOMS). 24 YOGA-TRAINED (YT; N = 12) AND NON-YOGA-TRAINED (CON; N = 12), MATCHED WOMEN VOLUNTEERS WERE ADMINISTERED A DOMS-INDUCING BENCH-STEPPING EXERCISE. MUSCLE SORENESS WAS ASSESSED AT BASELINE, 24, 48, 72, 96, AND 120 HOURS AFTER BENCH-STEPPING USING A VISUAL ANALOG SCALE (VAS). GROUPS WERE ALSO COMPARED ON BODY AWARENESS (BA), FLEXIBILITY USING THE SIT-AND-REACH TEST (SR), AND PERCEIVED EXERTION (RPE). STATISTICAL SIGNIFICANCE WAS ACCEPTED AT P </= 0.05. A 2 X 2 MIXED FACTORIAL ANOVA WITH REPEATED MEASURES AT 24 AND 48 HOURS REVEALED A SIGNIFICANT (P < 0.05) GROUP MAIN EFFECT WITH VAS SCORES GREATER FOR CON THAN YT. PAIRED T-TESTS REVEALED THAT IN YT, VAS SCORES WERE HIGHER BEFORE YOGA CLASS THAN AFTER YOGA CLASS AT 24 HOURS (21.4 [+/- 6.9] MM VS. 11.1 [+/- 4.1] MM; P = 0.02). THE SR WAS GREATER IN YT THAN IN CON (65.0 [+/- 7.9] CM VS. 33.3 [+/- 7.0] CM; P < 0.01); HOWEVER, NO DIFFERENCES WERE FOUND BETWEEN YOGA AND CONTROL IN BA (94.0 [+/- 4.4] UNITS VS. 83.8 [+/- 3.7] UNITS; P = 0.21) OR IN RPE AT 5-MINUTE INTERVALS (2.9 [+/- 0.3], 5.3 [+/- 0.8], 5.8 [+/- 0.9], AND 5.2 [+/- 0.8] VS. 2.5 [+/- 0.3], 4.0 [+/- 0.5], 4.2 [+/- 0.3], AND 4.9 [+/- 0.4]. YOGA TRAINING AND A SINGLE BOUT OF YOGA APPEAR TO ATTENUATE PEAK MUSCLE SORENESS IN WOMEN FOLLOWING A BOUT OF ECCENTRIC EXERCISE. THESE FINDINGS HAVE SIGNIFICANT IMPLICATIONS FOR COACHES, ATHLETES, AND THE EXERCISING PUBLIC WHO MAY WANT TO IMPLEMENT YOGA TRAINING AS A PRESEASON REGIMEN OR SUPPLEMENTAL ACTIVITY TO LESSEN THE SYMPTOMS ASSOCIATED WITH MUSCLE SORENESS.	2004

IMPROVED TIMED CHAIR STANDS (P < 0.01), 8-FOOT UP AND GO (P < 0.05), 2-MIN STEP TEST (P < 0.05), AND VERTICAL REACH (P = 0.05) PERFORMANCE WERE EVIDENT. ISOMETRIC KNEE FLEXOR STRENGTH (P < 0.05) AND REPETITIONS OF THE HEEL RISE TEST (P < 0.001) ALSO INCREASED FOLLOWING THE 32-WEEK INTERVENTION. BOTH FLEXIBILITY AND BALANCE PERFORMANCE REMAINED UNCHANGED. CONCLUSIONS. SIGNIFICANT IMPROVEMENTS IN PHYSICAL FUNCTION AND MUSCLE-SPECIFIC LOWER-EXTREMITY STRENGTH OCCUR WITH THE REGULAR PRACTICE OF A MODIFIED HATHA YOGA PROGRAM DESIGNED FOR SENIORS. THESE ADAPTATIONS CORRESPONDED WITH THE PREVIOUSLY REPORTED BIOMECHANICAL DEMANDS OF THE POSES.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
19  552  25 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
20 1757  33 POSITION OF THE HIP IN YOGA. BACKGROUND: YOGA IS GROWING IN POPULARITY AS A FORM OF EXERCISE THROUGHOUT THE WORLD. ORTHOPEDIC PATIENTS PARTICIPATE IN YOGA, YET LITTLE IS KNOWN ABOUT THE RANGES-OF-MOTION OF THE HIP WITHIN VARIOUS YOGA POSES. ORTHOPEDIC SURGEONS ARE UNSURE ABOUT WHAT POTENTIAL POSITIONS THEIR PATIENTS ARE PLACING THEIR HIPS DURING A YOGA PRACTICE. THE AIM OF THIS STUDY IS TO QUANTIFY THE DEGREE OF HIP MOTION WITH COMMON YOGA POSES. METHODS: TWENTY HEALTHY, REGULAR PRACTITIONERS OF YOGA PERFORMED 11 DIFFERENT YOGA POSES IN A STANDARDIZED FASHION. MOTION ANALYSIS WAS USED TO CAPTURE RANGE-OF-MOTION OF THE HIP DURING EACH POSE. RESULTS: MANY YOGA POSES PUT THE HIP IN EXTREMES OF MOTION. POSES SUCH AS DOWNWARD DOG, FORWARD FOLD, SEATED TWIST, AND PIGEON STRESSED THE HIP IN FLEXION. WARRIOR 1, WARRIOR 2, CRESCENT LUNGE, PIGEON, AND TRIANGLE STRESSED THE HIP IN EXTENSION. EAGLE AND SEATED TWIST PUT THE HIP IN HIGHER ADDUCTION, WHILE HALF MOON, EAGLE, AND TRIANGLE PRODUCED MORE HIP INTERNAL ROTATION. CONCLUSION: MANY POSES WERE FOUND TO REACH EXTREMES OF HIP MOTION. THIS STUDY MAY HELP GUIDE THE ORTHOPEDIC SURGEON IN COUNSELING HIP ARTHROPLASTY AND HIP IMPINGEMENT PATIENTS ABOUT YOGA-RELATED ACTIVITY. BY KNOWING WHICH POSES POTENTIALLY STRESS THE HIP IN PARTICULAR PLANES OF MOTION, SURGEONS MAY BETTER INFORM THEIR PATIENTS WHO ARE RETURNING TO YOGA AFTER INJURY OR SURGERY.	2018
