Individualized Training Based on Force-Velocity Profiling During Jumping in Ballet Dancers

Area of Science:

• Sports Science
• Biomechanics
• Dance Science

Background:

• Ballet dancers require exceptional jumping ability for demanding performances.
• Jump height is crucial for executing a wider range of technical skills and aesthetic elements.
• The force-velocity (F-V) profile is increasingly recognized as a key determinant of jumping performance.

Purpose of the Study:

• To investigate the effects of a 9-week individualized training program based on the F-V profile on countermovement jump (CMJ) performance in female ballet dancers.
• To assess changes in theoretical maximal force, theoretical maximal velocity, theoretical maximal power, and F-V imbalance (F-VIMB) following the training intervention.

Main Methods:

• A pre-post intervention study involving 46 female ballet dancers.
• Participants were divided into a control group (standard training) and an experimental group (9 weeks of individualized F-V profile-based training).
• Training involved 2 sessions per week, focusing on optimizing the F-V profile through loaded vertical jumps.

Main Results:

• The experimental group showed significant improvements in CMJ height (from 29.3 cm to 33.5 cm) with a large effect size.
• Key mechanical outputs improved, including theoretical maximal force and theoretical maximal velocity.
• A significant reduction in F-V imbalance (F-VIMB) was observed in the experimental group (from 43.8% to 24.9%) with a very large effect size.

Conclusions:

• Individualized training programs targeting the F-V profile, particularly F-VIMB, are effective for enhancing CMJ height in female ballet dancers.
• Optimizing the force-velocity relationship is a viable strategy to improve athletic performance in ballet.
• This study provides evidence for a targeted training method to improve a critical physical attribute in ballet.
