Effect of Dance Experience on Loading Patterns Among Ballroom Dancers

Area of Science:

• Biomechanics
• Kinesiology
• Dance Science

Background:

• Ballroom dance is increasingly popular for its competitive, social, and health advantages.
• Limited biomechanical data exists for ballroom dance, particularly concerning ground reaction forces.
• Understanding dance kinetics is crucial for injury prevention and performance enhancement.

Purpose of the Study:

• To quantify vertical ground reaction force (vGRF) and loading rate during common American rhythm ballroom dance steps.
• To compare vGRF and loading rate across different experience levels (inexperienced, recreational, professional).
• To analyze the variance of these biomechanical variables with increasing dance expertise.

Main Methods:

• Fifty-six participants (20 inexperienced, 18 recreational, 18 professional) performed nine American rhythm ballroom dance elements.
• Dance movements included Rumba box step and Cha Cha Cha foundational steps performed over force plates.
• Statistical analysis utilized Kruskal-Wallis and Levene's tests to compare force variables and variances across experience levels.

Main Results:

• Vertical ground reaction force and loading rate were significantly associated with dance experience for eight of nine elements (p < 0.040).
• Inexperienced dancers exhibited the highest forces, while professional dancers showed the lowest, particularly in backward and leftward steps.
• Variance in force measurements decreased significantly with higher levels of dance experience.

Conclusions:

• This study provides foundational kinetic insights into American rhythm ballroom dance movements.
• Dance experience significantly influences impact forces and loading rates, suggesting adaptive biomechanical strategies.
• Findings highlight the need for further research into ballroom dance biomechanics and injury mechanisms.
