Does a visual reference help ballet dancers turn more successfully?

Area of Science:

• Dance science
• Biomechanics
• Motor control

Background:

• Performing multiple rotations requires exceptional skill in ballet.
• Previous research on ballet rotations primarily focused on biomechanics, neglecting visual information's role.
• The influence of visual cues on continuous turns like Fouettés or à la Seconde remains understudied.

Purpose of the Study:

• To investigate the impact of a visual reference on balance control and head coordination (spotting) in elite ballet dancers during continuous rotations.
• To analyze how visual information affects performance over a series of consecutive turns.

Main Methods:

• 12 skilled ballet dancers (6 female, 6 male) performed 12 consecutive Fouetté or à la Seconde turns with and without a visual reference.
• Dependent measures included supporting foot path length (balance), spotting duration, head isolation, and orientation (pelvic deviation).
• Linear mixed models analyzed the effects of visual conditions and performance progression.

Main Results:

• Overall, dancers exhibited a smaller supporting foot path length without a visual reference.
• Dancers demonstrated improved orientation towards the front when a visual reference was present.
• Over consecutive turns, dancers with a visual reference reduced path length and improved orientation, while those without increased spotting duration and head isolation.

Conclusions:

• A visual reference is crucial for elite ballet dancers to sustain performance during multiple rotations, primarily by enhancing balance and orientation.
• The importance of visual references increases with the number of consecutive turns performed.
• Dancers adapt their strategies, increasing head isolation, particularly towards the end of turns, regardless of visual conditions.
