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

Defining Aesthetics
Supplemental Training Does Not
Improve Aesthetic Competence
Intensity insufficient to satisfy ACSM
guidelines for exercise training.
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
