1 1283 136 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.

2 1654  41 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
3   58  43 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
4 1290  26 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
5 1095  24 EFFECTS OF YOGA PRACTICE ON MUSCULAR ENDURANCE IN YOUNG WOMEN. THE AIM OF THIS STUDY WAS TO VERIFY THE EFFECTS OF A SYSTEMATIZED YOGA PRACTICE ON MUSCULAR ENDURANCE IN YOUNG WOMEN. TWENTY SIX WOMEN (24 +/- 3.5 YEARS OLD) PARTICIPATED IN SIX WEEKS OF YOGA CLASSES, AND TWENTY ONE WOMEN (25 +/- 5.1 YEARS OLD) PARTICIPATED AS THE CONTROL GROUP. THE YOGA INTERVENTION WAS COMPOSED OF EIGHTEEN SESSIONS, THREE TIMES PER WEEK, AT 1 H PER SESSION. THE MUSCULAR ENDURANCE OF UPPER LIMBS (PUSH-UP) AND ABDOMINAL (SIT-UP) WAS ASSESSED THROUGH THE PROTOCOL SUGGESTED BY GETTMAN (1989) [1] AND GOLDING, MYERS AND SINNING (1989) [2] TO THE MAXIMUM REPETITIONS PERFORMED IN 1 MIN. TO VERIFY THE SIGNIFICANT DIFFERENCES INTRA GROUPS AND BETWEEN GROUPS A SPANOVA WAS PERFORMED, AND THE LEVEL OF SIGNIFICANCE WAS P </= 0.05. THE FINDINGS SUGGEST THAT YOGA PROVIDES IMPROVEMENT IN UPPER LIMB AND IN ABDOMINAL MUSCULAR ENDURANCE.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
6   80  30 A MATHEMATICAL METHOD FOR ELECTROMYOGRAPHY ANALYSIS OF MUSCLE FUNCTIONS DURING YOGASANA. CONTEXT: FOR THE PAST FEW DECADES, THE NUMBER OF PEOPLE PRACTICING YOGA IS INCREASING IN NUMBER. YOGASANAS NEED SMOOTH BODY MOVEMENTS IN THE PROCESS OF ATTAINING DEFINED POSTURES THAT THE PERSON MUST HOLD ON TO ACTIVATE SPECIFIC MUSCLES OF THE BODY RELATED TO THAT ASANA. YOGASANAS SHOULD BE PERFORMED WITH PERFECTION TO DERIVE MAXIMUM BENEFITS. OBJECTIVE: THE OBJECTIVE OF THIS STUDY WAS TO INTRODUCE A MATHEMATICAL METHOD TO UNDERSTAND MUSCLE FUNCTIONALITIES WHILE DOING YOGASANAS. MATERIALS AND METHODS: USED DELSYS SURFACE ELECTROMYOGRAPHY (SEMG) - TRIGNO (DELSYS INC.) SENSORS FOR DATA RECORDING AND ANALYZING MUSCLE ACTIVATION PATTERNS. RESULTS: PERFORMANCE ANALYSIS WAS QUANTIFIED USING NORMALIZED SEMG SIGNALS. THE SEMG DATA DURING FINAL POSTURE WERE FIT TO A STRAIGHT LINE USING LINEAR REGRESSION ANALYSIS. CONCLUSION: THE RESULTS SUGGESTED THAT THE SLOPE OF THE BEST FIT LINE IS A GOOD METRIC FOR MONITORING THE MUSCLE ACTIVITY DURING YOGA PERFORMANCE. THE ADVANTAGES OF THIS METHOD ARE THE SLOPE OF THE LINE IS A GOOD INDICATOR FOR MONITORING THE MUSCLE ACTIVITY WHILE DOING YOGASANA AND THE METHOD SUGGESTED IN THIS STUDY CAN BE EXTENDED FOR ANALYZING OTHER ASANAS AS WELL.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
7 1757  36 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
8  417  28 BODY TEMPERATURE IN PRACTITIONERS OF A YOGA BREATHING TECHNIQUE CONSIDERED TO BE HEAT GENERATING. CONTEXT: SURYABHEDA PRANAYAMA IS TRADITIONALLY DESCRIBED AS "INCREASING THE INNER FIRE" AND IS BELIEVED TO BE HEAT GENERATING. AIMS: THE PRESENT STUDY AIMED AT DETERMINING WHETHER THE SURFACE BODY TEMPERATURE WOULD INCREASE AFTER SURYABHEDA PRANAYAMA PRACTICE COMPARED WITH SITTING QUIETLY FOR THE SAME DURATION AS A CONTROL. MATERIALS AND METHODS: NINETEEN PARTICIPANTS WITH EXPERIENCE OF SURYABHEDA PRANAYAMA PRACTICE (GROUP MEAN EXPERIENCE +/- STANDARD DEVIATION, 30.2 +/- 22.8 MONTHS) WERE ASSESSED IN 3 SESSIONS ON SEPARATE DAYS. THE SESSIONS WERE (I) SURYABHEDA PRANAYAMA WITH PHYSIOLOGICAL LOCKS OR BREATH RETENTION, (II) SURYABHEDA PRANAYAMA WITHOUT PHYSIOLOGICAL LOCKS OR BREATH RETENTION, AND (III) QUIET SITTING (CONTROL SESSION). THE AXILLARY SURFACE BODY TEMPERATURE WAS MONITORED IN ALL THREE SESSIONS BEFORE (5 MIN), DURING (15 MIN), AND AFTER (5 MIN) THE INTERVENTION. AMBIENT TEMPERATURE AND HUMIDITY IN THE RECORDING CABIN USED FOR TESTING WERE NOTED. FROM THE AMBIENT TEMPERATURE AND HUMIDITY, THE HEAT INDEX WAS DERIVED. STATISTICAL ANALYSIS: REPEATED MEASURES ANALYSES OF VARIANCE WERE PERFORMED TO COMPARE VALUES BEFORE, DURING, AND AFTER THE 3 SESSIONS, USING SPSS VERSION 24.0. RESULTS: THE SURFACE BODY TEMPERATURE INCREASED DURING AND AFTER SURYABHEDA PRANAYAMA WITH PHYSIOLOGICAL LOCKS (P < 0.001; P < 0.001), SURYABHEDA PRANAYAMA WITHOUT PHYSIOLOGICAL LOCKS (P < 0.01; P < 0.001), AND QUIET SITTING (P < 0.001; P < 0.001) COMPARED TO THE RESPECTIVE BEFORE VALUES. CONCLUSION: THE CONTROL (I.E., QUIET SITTING) AND EXPERIMENTAL SESSIONS (I.E., SURYABHEDA WITH LOCKS AND SURYABHEDA WITHOUT LOCKS) SHOWED A COMPARABLE INCREASE IN THE SURFACE BODY TEMPERATURE. HENCE, THE INCREASE IN SURFACE BODY TEMPERATURE DURING AND AFTER EXPERIMENTAL SESSIONS DOES NOT APPEAR TO BE RELATED TO THE PRANAYAMA TECHNIQUES. THE POSSIBLE FACTORS WHICH MAY HAVE CONTRIBUTED TO INCREASED SURFACE BODY TEMPERATURE IN THE CONTROL AND EXPERIMENTAL SESSIONS HAVE BEEN DISCUSSED.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
9 2340  32 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
10 1301  32 HATHA YOGA ON BODY BALANCE. BACKGROUND: A GOOD BODY BALANCE REQUIRES A PROPER FUNCTION OF VESTIBULAR, VISUAL, AND SOMATOSENSORY SYSTEMS WHICH CAN BE REACH WITH EXERCISE PRACTICE AND/OR YOGA. AIM: TO DETERMINE THE EFFECTS OF A 5-MONTH HATHA YOGA TRAINING PROGRAM ON BODY BALANCE IN YOUNG ADULTS. MATERIALS AND METHODS: THIS STUDY USED A CONTROLLED, NONRANDOMIZED DESIGN, WHERE THE EXPERIMENTAL GROUP UNDERWENT A 5-MONTH TRAINING PROGRAM AND WERE THEN COMPARED WITH THE CONTROL GROUP THAT HAD A SEDENTARY LIFESTYLE. A CONVENIENCE SAMPLE OF 34 OUT OF 40 MEN AGED 25-55 YEARS OLD (34.0 +/- 0.9) WERE DEEMED ELIGIBLE FOR THIS STUDY. THEY WERE RANDOMLY DIVIDED INTO TWO GROUPS: EXPERIMENTAL AND CONTROL GROUPS. SUBJECTS IN THE EXPERIMENTAL GROUP WERE ENGAGED IN 60 MIN SESSIONS OF HATHA YOGA THREE TIMES A WEEK FOR 5 MONTHS. WE EVALUATED POSTURAL CONTROL BY MEASURING THE LIMIT OF STABILITY AND VELOCITY OF OSCILLATION (VOS) IN THREE CONDITIONS OF THE BALANCE REHABILITATION UNIT (BRU) AND THROUGH FIELD PROCEDURES (FOUR POSITION, PLANE, FLAMINGO, HOPSCOTCH, AND DYNAMIC TEST). RESULTS: WE OBSERVED DIFFERENCES (P < 0.05) IN POSTINTERVENTION SCORES BETWEEN THE GROUPS REGARDLESS OF BRU PARAMETERS AND FIELD PROCEDURES (EXCEPT FOR FLAMINGO) EVEN AFTER ADJUSTING FOR PREINTERVENTION SCORES, SUGGESTING THAT THESE CHANGES WERE INDUCED BY HATHA YOGA TRAINING. THE PARTIAL ETA SQUARED ON BRU PARAMETERS RANGED FROM 0.78 (VOS1)-0.97 (COP2), AND FROM 0.00 (FLAMINGO)-0.94 (FOUR POSITION) FOR THE FIELD PROCEDURES. CONCLUSIONS: OUR RESULTS PROVIDE SUBSTANTIAL EVIDENCE THAT POSTURAL CONTROL IN HEALTHY YOUNG ADULTS CAN BE IMPROVED THROUGH PRACTICING HATHA YOGA.	2014

THE DATA COLLECTED FROM 8 INDIVIDUALS (4 MALES 4 FEMALES) ON THE DEGREE OF MUSCLE RELAXATION AT THE END OF MEDITATION REVEALED A SIGNIFICANTLY DECREASED MUSCLE ACTIVITY AMOUNTING TO 58% OF THE BASAL LEVEL IN BOTH THE SEXES.	1990	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
12  295  34 AGE RELATED DIFFERENCES OF SELECTED HATHA YOGA PRACTICES ON ANTHROPOMETRIC CHARACTERISTICS, MUSCULAR STRENGTH AND FLEXIBILITY OF HEALTHY INDIVIDUALS. BACKGROUND: PHYSIOLOGICAL BENEFITS OF YOGA ON VOLUNTEERS OF A PARTICULAR AGE GROUP ARE AVAILABLE. HOWEVER, REPORTS ON EFFICACY OF A SPECIFIC YOGA PACKAGE ON THE POPULACE OF DIFFERENT AGE GROUPS FROM SIMILAR OCCUPATIONAL BACKGROUND IS STILL VERY LIMITED. THEREFORE, THE PRESENT STUDY WAS CONDUCTED TO APPRAISE THE EFFECT OF A SPECIFIC HATHA YOGA PACKAGE ON ANTHROPOMETRIC CHARACTERISTICS, FLEXIBILITY AND MUSCULAR STRENGTH OF HEALTHY INDIVIDUALS OF DIFFERENT AGE GROUPS FROM SIMILAR OCCUPATIONAL TRADE. MATERIALS AND METHODS: A TOTAL OF 71 PARTICIPANTS (GROUP ALL) FROM INDIAN AIR FORCE GROUND PERSONNEL VOLUNTEERED AND AGE WISE DIVIDED INTO 3 GROUPS - (I) GROUP I (GR. - I) (N1 = 27, 20-29 YEARS), (II) GROUP II (GR. - II) (N2 = 21, 30-39 YEARS) AND (III) GROUP III (GR. - III) (N3 = 23, 40-49 YEARS). ALL THE PARTICIPANTS UNDERGONE SELECTED HATHA YOGA TRAINING FOR 1 H DAILY FOR A PERIOD OF 12 WEEKS. PARAMETERS WERE RECORDED BEFORE AND AFTER THE TRAINING. PRE AND POST TRAINING DIFFERENCES WERE ASSESSED BY STUDENT'S T-TEST. RESULTS: BODY WEIGHT (ALL, GR. - II AND GR. - III [ALL P < 0.05]), BODY MASS INDEX (GR. - II AND GR. - III [BOTH P < 0.01]) AND FAT% (GR. - II AND III [BOTH P < 0.05]) WERE DECREASED SIGNIFICANTLY. NECK CIRCUMFERENCE WAS INCREASED SIGNIFICANTLY IN GR. - I (P < 0.05) BUT DECREASED SIGNIFICANTLY IN GR. - III (P < 0.05). CHEST CIRCUMFERENCE (ALL (P < 0.001), IN GR. - I AND II [BOTH P < 0.05]), GRIP STRENGTH (ALL [LEFT: P < 0.01 AND RIGHT: P < 0.05], IN GR. - I [LEFT: P < 0.05 AND RIGHT: P < 0.01], IN GR. - II [RIGHT: P < 0.05] AND IN GR. - III [LEFT: P < 0.05 AND RIGHT: P < 0.01]), BACK LEG STRENGTH (GROUP WISE P < 0.001, P < 0.05, P < 0.01 AND P < 0.05 RESPECTIVELY) AND FLEXIBILITY (ALL P < 0.001) WERE INCREASED SIGNIFICANTLY. SUMMARY AND CONCLUSION: HATHA YOGA CAN IMPROVE ANTHROPOMETRIC CHARACTERISTICS, MUSCULAR STRENGTH AND FLEXIBILITY AMONG VOLUNTEERS OF DIFFERENT AGE GROUP AND CAN ALSO BE HELPFUL IN PREVENTING AND ATTENUATING AGE RELATED DETERIORATION OF THESE PARAMETERS.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
13  552  43 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
14 2085  31 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
15  850  28 EFFECT OF YOGA ON SHORT-TERM HEART RATE VARIABILITY MEASURE AS A STRESS INDEX IN SUBJUNIOR CYCLISTS: A PILOT STUDY. SUBJUNIOR ATHLETES EXPERIENCE MENTAL STRESS DUE TO PRESSURE FROM THE COACH, TEACHERS AND PARENTS FOR BETTER PERFORMANCE. STRESS, IF REMAINS FOR LONGER PERIOD AND NOT MANAGED APPROPRIATELY CAN LEADS TO NEGATIVE PHYSICAL, MENTAL AND COGNITIVE IMPACT ON CHILDREN. THE PRESENT STUDY WAS AIMED TO EVALUATE THE EFFECT OF INTEGRATED YOGA MODULE ON HEART RATE VARIABILITY (HRV) MEASURE AS A STRESS INDEX IN SUBJUNIOR CYCLISTS. FAST FURRIER TRANSFORM TECHNIQUE OF FREQUENCY DOMAIN METHOD WAS USED FOR THE ANALYSIS OF HRV. WE HAVE FOUND A SIGNIFICANT INCREASE IN HIGH FREQUENCY (HF) COMPONENT BY 14.64% (P < 0.05) AND DECREASE IN THE LOW FREQUENCY COMPONENT (LF) OF HRV SPECTRUM BY 5.52% (P < 0.05) AND A DECREASE IN LF/HF RATIO BY 19.63% (P < 0.01) IN YOGA GROUP. IN THE CONTROL GROUP, THERE WAS DECREASE IN THE HF COMPONENT AND, NO SIGNIFICANT DIFFERENCE IN THE LF COMPONENT OF HRV SPECTRUM AND LF/HF RATIO. THE RESULTS SHOW THAT YOGA PRACTICE DECREASES SYMPATHETIC ACTIVITY AND CAUSES A SHIFT IN THE AUTONOMIC BALANCE TOWARDS PARASYMPATHETIC DOMINANCE INDICATING A REDUCTION IN STRESS. IN CONCLUSION, YOGA PRACTICE HELPS TO REDUCE STRESS BY OPTIMIZING THE AUTONOMIC FUNCTIONS. SO, IT IS SUGGESTED TO INCORPORATE YOGA MODULE AS A REGULAR FEATURE TO KEEP SUBJUNIOR ATHLETES BOTH MENTALLY AND PHYSICALLY FIT.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
16 1988  34 SPECTRAL PARAMETERS OF HRV IN YOGA PRACTITIONERS, ATHLETES AND SEDENTARY MALES. PHYSICAL INACTIVITY IS AN IMPORTANT RISK FACTOR FOR CARDIOVASCULAR MORTALITY AND MORBIDITY. EXERCISE IS CONSIDERED AN ACCEPTABLE METHOD FOR IMPROVING AND MAINTAINING PHYSICAL AND EMOTIONAL HEALTH. ALTHOUGH YOGA IS HISTORICALLY A SPIRITUAL DISCIPLINE, A GROWING BODY OF EVIDENCE SUPPORTS THE BELIEF THAT YOGA BENEFITS PHYSICAL AND MENTAL HEALTH. THE OBJECTIVE OF THIS STUDY WAS TO EVALUATE HEART RATE VARIABILITY WHICH REFLECTS AUTONOMIC CONTROL OF HEART AMONG YOGA PRACTITIONERS, ATHLETES AND INDIVIDUALS WITH SEDENTARY LIFESTYLE. THE STUDY WAS CARRIED OUT IN THE DEPARTMENTS OF PHYSIOLOGY AT MAMC AGROHA, HISAR AND PT. BD SHARMA PGIMS ROHTAK, HARYANA. THE STUDY GROUP COMPRISED OF 1200 HEALTHY MALE VOLUNTEERS OF 16 TO 55 YEARS OF AGE. THE STUDY GROUP WAS DIVIDED INTO FOUR AGE GROUPS: GROUP A OF AGE 16 TO 25 YEARS; GROUP B OF AGE 26 TO 35 YEARS; GROUP C OF AGE 36 TO 45 YEARS AND GROUP D OF AGE 46 TO 55 YEARS. ALL AGE GROUPS WERE FURTHER DIVIDED INTO THREE CATEGORIES I.E ATHLETE (RUNNER), YOGA (YOGA PRACTITIONERS) AND SEDENTARY IN WHICH INDIVIDUALS WITH SEDENTARY LIFE STYLE WERE INCLUDED. THE BASAL RECORDING OF ECG IN LEAD II WAS DONE FOR 5 MINUTES. THE POLYRITE-D ECG DATA WAS USED FOR ANALYSIS OF HEART RATE VARIABILITY BY FREQUENCY DOMAIN METHOD. TWO SPECTRAL COMPONENTS WERE RECORDED NAMELY HIGH FREQUENCY (HF) COMPONENT (0.15-0.4 HZ), AN INDICATOR OF VAGAL EFFERENT ACTIVITY AND LOW FREQUENCY (LF) COMPONENT (0.04-.15 HZ), REPLICATOR OF COMPOSITE SYMPATHO-VAGAL INTERPLAY. HF COMPONENT IN NORMALIZED UNIT WAS FOUND SIGNIFICANTLY HIGH IN AGE GROUP B AND C IN YOGA PRACTITIONERS AND ATHLETES AS COMPARED TO SEDENTARY INDIVIDUALS AND IN AGE GROUP D SIGNIFICANTLY HIGH IN YOGA PRACTITIONERS AS COMPARED TO ATHLETES AND SEDENTARY INDIVIDUALS. SIGNIFICANTLY DECREASED LF/HF RATIO WAS FOUND IN AGE GROUP B AND C IN YOGA AND ATHLETE SUBJECTS AS COMPARED TO SEDENTARY INDIVIDUALS AND IN AGE GROUP D IN YOGA PRACTITIONERS AS COMPARED TO ATHLETES AND SEDENTARY INDIVIDUALS. THIS INDICATES THAT PARASYMPATHETIC ACTIVITY IS SUBSTANTIALLY GREATER IN YOGA PRACTITIONERS.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
17  987  29 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
18 2757  24 YOGA PRACTICES AND PSYCHOLOGICAL WELL-BEING OF STUDENT NURSES. YOGA HAS BEEN WITH US SINCE TIME IMMEMORIAL, BUT IT IS ONLY DURING RECENT YEARS THAT IT HAS ASSUMED WORLDWIDE IMPORTANCE. THE AIM OF THE STUDY WAS TO ASSESS THE CT OF SELECTED YOGA PRACTICES ON PSYCHOLOGICAL WELLBEING. IN THIS QUASI-EXPERIMENTAL ONE GROUP PRE-TEST AND POST- TEST STUDY, 83 UNDER GRADUATE STUDENT NURSES. WERE TAUGHT SELECTED YOGA EXERCISES. THE SE- LECTED YOGA EXERCISES WERE SYSTEMATIC RELAXATION, BREATHING, AND STRETCHING THAT WERE PER- FORMED IN THE FORMATIVE MANNER. THE' INTERVENTION WAS CARRIED OUT FOR THE MINIMAL DURATION OF ONE HOUR PER DAY, THREE DAYS A WEEK FOR A PERIOD OF 6 WEEKS. ASSESSMENT WAS- CARRIED OUT ON THE FIRST AND LAST- DAY OF THE INTERVENTION, USING-A MODIFIED HINDI VERSION OF POSITIVE AFFECT AND NEGATIVE AFFECT SCALE, (PANAS-H). IT,HAS 10 QUESTIONS EACH TO MEASURE POSITIVE (PA) AND NEGA- TIVE AFFECT (NA). SINCE THE DATA WAS TESTED AND FORMED A NORMAL DISTRIBUTION, THE PAIRED 'T' TEST WAS USED FOR STATISTICAL ANALYSIS. THE. MEAN PA SCORE OF 42.92 AFTER YOGA PRACTICE WAS STATISTI- CALLY HIGHER THAN THE MEAN PA SCORE OF 32. 50 BEFORE YOGA PRACTICE (P=O. 01). THE MEAN NA SCORE OF 20.75 AFTER YOGA PRACTICE WAS LOWER THAN THE MEAN NA SCORE OF 23.33 BEFORE YOGA PRACTICE (P=0.427). THE YOGA PRACTICE CAN BE TAUGHT TO NORMALPARTICIPANTS AS IT MAY REDUCE NEGATIVE AFFECT AND INCREASE THE POSITIVE AFFECT WITHIN A FEW WEEKS.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
19  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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
20  509  34 COMPARATIVE IMMEDIATE EFFECT OF DIFFERENT YOGA ASANAS ON HEART RATE AND BLOOD PRESSURE IN HEALTHY YOUNG VOLUNTEERS. INTRODUCTION: THIS STUDY PLANNED TO COMPARE IMMEDIATE CARDIOVASCULAR EFFECTS OF DIFFERENT YOGA ASANAS IN HEALTHY YOUNG VOLUNTEERS. MATERIALS AND METHODS: HEART RATE (HR), SYSTOLIC PRESSURE (SP), AND DIASTOLIC PRESSURE (DP), BLOOD PRESSURE (BP), WERE RECORDED USING THE NON INVASIVE BLOOD PRESSURE (NIBP) APPARATUS IN 22 HEALTHY YOUNG SUBJECTS, BEFORE AND AFTER THE PERFORMANCE OF DHANURASANA (DA), VAKRASANA (VA) (BOTH SIDES), JANUSIRASASANA (JSA) (BOTH SIDES), MATSYASANA AND SHAVASANA FOR 30 S. HR AND BP WERE FURTHER RECORDED DURING SUPINE RECOVERY AT 2, 4, 6, 8, AND 10 MIN. A REPEATED MEASURE OF ANOVA WAS USED FOR STATISTICAL ANALYSIS. RESULTS: THERE WERE SIGNIFICANT CHANGES IN HR AND BP BOTH IMMEDIATELY AFTER THE ASANAS AS WELL AS DURING THE RECOVERY PERIOD. OVERALL COMPARISONS OF % CHANGES IMMEDIATELY AFTER THE PERFORMANCE OF THE ASANAS REVEALED SIGNIFICANT DIFFERENCES WITH REGARD TO HR THAT INCREASED SIGNIFICANTLY AFTER DA. IN THE RECOVERY PHASE, THERE WERE SIGNIFICANT INTERGROUP DIFFERENCES FROM 2 MIN ONWARD IN BOTH SP AND DP. THE DECREASE OF SP AFTER VA (RIGHT SIDE) (VA-R) WAS SIGNIFICANTLY GREATER THAN SHAVASANA (4(TH), 6(TH), AND 8(TH) MIN) AND JSA (LEFT SIDE) (JSA-L) AT 6(TH) AND 8(TH) MIN. DP DECREASED SIGNIFICANTLY AFTER PERFORMING JSA-L COMPARED TO VA-R AT THE 6(TH) AND 8(TH) MIN. DISCUSSION: THE CARDIOVASCULAR CHANGES IMMEDIATELY AFTER THE ASANAS AND DURING THE RECOVERY PHASE REVEAL INHERENT DIFFERENCES BETWEEN THE SELECTED POSTURES. THE RISE OF HR IN DA MAY BE ATTRIBUTED TO INCREASED SYMPATHETIC RESPONSE DUE TO THE RELATIVE DIFFICULTY OF THE POSTURE AS WELL AS ABDOMINAL COMPRESSION OCCURRING IN IT. THE EFFECT OF SUPINE RELAXATION IS MORE PRONOUNCED AFTER THE PERFORMANCE OF THE ASANAS AS COMPARED TO MERE RELAXATION IN SHAVASANA. THIS MAY BE ATTRIBUTED TO A NORMALIZATION AND RESULTANT HOMEOSTATIC EFFECT OCCURRING DUE TO A GREATER, HEALTHIER DE-ACTIVATION OF THE AUTONOMIC NERVOUS SYSTEM OCCURRING TOWING TO THE PRESENCE OF PRIOR ACTIVATION. THERE WERE ALSO SUBTLE DIFFERENCES BETWEEN THE RIGHT SIDED AND LEFT SIDED PERFORMANCE OF VA AND JSA THAT MAY BE OCCURRING DUE TO THE DIFFERENT INTERNAL STRUCTURES BEING EITHER COMPRESSED OR RELAXED ON EITHER SIDE. CONCLUSION: OUR STUDY PROVIDES INITIAL EVIDENCE OF DIFFERENTIAL CARDIOVASCULAR EFFECTS OF ASANAS AND SUBTLE DIFFERENCES BETWEEN RIGHT AND LEFT SIDED PERFORMANCE. FURTHER, CARDIOVASCULAR RECOVERY IS GREATER AFTER THE PERFORMANCE OF THE ASANAS AS COMPARED TO SHAVASAN; THUS, IMPLYING A BETTER RESPONSE WHEN EFFORT PRECEDES RELAXATION.	2014
