The Effect of Supplemental Training on Dance Aesthetic Competence A Meta-Analysis Ilka Felsen DPTc PT 209-910 Background Aesthetics: “It takes an athlete to dance, but a dancer to be an artist.” -Shanna LaFleur Aesthetics Goal of dancers Mackrell 2014 Defining Aesthetics Aesthetic Competence Tool Angioi et al. 2009 Criterion Description Mark 1-10 1. Control of movements Controlled landing from jump/turn, controlled lifting/lowering of limbs, controlled shifting of body weight. Core strength, alignment, posture. 1-3: Some evidence of coordination, movement control, and body awareness, but limited and inconsistent. 4-6: Some elements were stronger than others. 7-8: Secure general coordination and body alignment; generally well controlled movements. 9-10: Well coordinated movement and controlled work all of the time, with accurate alignment. 2. Spatial skills Spatial awareness, accuracy and intent. 1-3: Little or no use of peripheral space; poor use of performance space. 4-6: Some good use of space, but inconsistent. Some elements stronger than others. 7-8: Good use of space about 80% of the time, with general accuracy and intent. 9-10: Secure and confident use of space, with accuracy and intent. 3. Accuracy of movements Arm placement, feet positions, fully stretched leg extensions (if required). 1-3: Little or no precision throughout sequence. Unclear leg/arm lines. 4-6: Some precision, but inconsistent. Some elements stronger than others. 7-8: Correct positioning about 80% of the time. 9-10: Precise placing with well articulated gestures of limbs. 4. Technique Elevation, turning and falling techniques, height of extensions, balance, posture, placement, articulation. 1-3: Little or no evidence of high technical skills in any element. 4-6: Some skill in some elements, general virtuosity achieved. 7-8: Good virtuosity shown about 80% of the time. 9-10: A stunning performance showing virtuosity and skill throughout. 5. Dynamics, timing, and rhythmical accuracy Dancing with correct timing and ability to perceive movement and rhythmic patterns. Showing awareness for changes in musical dynamics and phrasing. 1-3: Little or no ability to perform and respond in time to the music. Little or no dynamic qualities. 4-6: Performed in time for over half of the sequence, with some ability to respond to different rhythms and dynamics of movement. 7-8: Timing was accurate for most of the sequence, and response to varying rhythms was shown. General good use of dynamics. Good sense of musicality. 9-10: Timing was accurate throughout, with very good response to various rhythms, dynamics, and phrases. 6. Performance qualities Ability to execute the work for an audience. Presence, expressiveness, memory recall. 1-3: Few or no performance qualities were shown. Poor memory recall. 4-6: Some performance qualities were shown. Generally good memory recall. 7-8: Strong expressive qualities and memory recall about 80% of the time. 9-10: Excellent and well developed projection of a range of expressions, feelings and emotions. Mature approach, with understanding of motivation for the movement. 7. Overall performance Does the performance overall impress markers? 1-3: Dancer made little impression on the audience. 4-6: Dancer not at full potential yet, OR strong work but lacking ability to impress overall. 7-8: Dancer has the ability to shine, but was hindered by minor aspects of performance. 9-10: Impressive! Significance Input Result Clinical Problem Theoretical Construct • Dancers are limited in their aesthetic competence by inadequate physical fitness. • Supplemental training has been shown to improve physical fitness parameters in dancers. • Supplemental training should improve aesthetic competence. Gap • Variety of interventions and disciplines • Addressing this gap: • Grand effect size across studies • Only 2 studies • Addressing this gap: • Several newly published studies • Examine multiple disciplines Purpose Understand the effect of supplemental training on dance aesthetic competence. Elucidate what training protocols will produce desired training effects to achieve aesthetic competence. Relevance Physical therapists may: • With dance educators on curriculum • Optimal supplemental training protocols • And develop supplemental training program Definitions Primary Question • What is the effect of supplemental training on dance aesthetic competence? Population, Intervention, Comparison, Outcome P I C O Hypothesis Expected Findings • 3 studies to address primary question • All level 2b or higher • Result: supplemental training improves dance aesthetics Methods Search Procedures • Experimental studies published in English • Ballet, contemporary, or modern dance students or professionals • Intervention consisting of strength, circuit, aerobic, or WBV training • Outcomes of aesthetic competence • Ages 16-30 • Intervention consisting of specific dance movement, stretch, or exercise • Dancers already partaking in supplemental training • Pubmed • PEDro • Web of Science Cochrane CINAHL • Fitness and dance • Supplemental and dance • Supplementary and dance performance • Exercise and dance performance Training and dance aesthetic Exercise and dance quality Training and dance Statistics • Within and between group effect sizes calculated • 95% confidence interval • Grand effect sizes calculated • 95% confidence interval • Q statistic to determine random or fixed effects model for grand effect size • P<0.05 indicates use of random effects model Results PRISMA Database Search N=1081 Recursive Search N=24 Duplicates Excluded N=83 Title and Abstract Screened N=1022 Excluded N=1013 Full Text Reviewed N=9 Excluded: • • • Studies Included in Analysis N=5 Unable to obtain full text (N=2) No intervention (N=1) Not ballet, contemporary, or modern dancers (N=1) Results • Grand effect size: • Within group: 0.81, CI 0.02 to 1.61 • Between group: 0.58, CI -0.16 to 1.32 • Random effects model used • Within group p = 0.0069 • Between group p=0.02 • Clinical Units • 10.47 Statistical Analysis of Study Outcomes CI=confidence interval, SE=standard error Within Group Comparison: Aesthetic Competence Improvement Effect size does not cross zero: Significant Between Group Comparison: Aesthetic Competence Improvement Effect size crosses zero: Not significant Subanalysis Physiological Aesthetic Competence Subanalysis: Strength Subanalysis: Anaerobic Endurance Not significant Subanalysis: Power Not significant Subanalysis: Aerobic Capacity Harm and Cost • No studies reported any adverse events. • Monetary cost was not discussed. • WBV training: 10 min per session. • Many studios have resources for supplemental training. • Supplemental training may be associated with savings.

Dancers achieved improvements in physiological AC parameters, but: •Prevents emergence of adequate differences in physiological aesthetic competence. •Improvement was insufficient to affect visual AC. •Dancers need practice to incorporate new physical capabilities into technique. AC tools were mostly created individually for studies, but have no validity determined, consequently they: •May not sense visual aesthetic elements affected by physiological parameters. Dancers may have unique aesthetic competence deficiencies, that need to be trained individually. Limitations Heterogeneous supplemental program, AC tools, and subjects Small number of subjects Low level of evidence, 4-6 on PEDro Scale Studies Did not clarify which areas of AC tool were improved Some physiological requirements not directly addressed Performed by 1 researcher Search performed on 5 databases Research Process Directions for further research Investigate effect of individualized supplemental training programs based on dancer-specific physiological deficits. Use standardized AC tool agreed upon by dance community. Link physiological improvements to specific AC tool criteria. Link modality of exercise to visual aesthetic improvement. Determine ideal parameters: intensity, duration, intensity. Implications for practice Conclusion Primary References • Angioi M, Metsios G, Twitchett E, Koutedakis Y, Wyon M.
