Influencia de los estiramientos estáticos en el rendimiento del salto reactivo durante la clase de danza clásica

Introduction: Dancers require flexibility and power to achieve peak performance. Within the context of classical ballet classes, static stretching prior to centre work is an integral part of the discipline’s methodology. However, the physiological effects of this stretching may lead to a reduction in the performance of the back jump performed at the centre. Objective: To determine whether static stretching prior to centre work during a ballet class affects the performance of the back jump in classical ballet dancers. Methodology: This study followed a balanced, quantitative, experimental, cross-sectional design with repeated measures between subjects (cross-over). Three measurements of the CMJ test were taken at different points during the ballet class to assess jump performance in 22 ballet dancers from the Conservatorio Superior de Danza de Málaga following the application of a static stretching protocol (SP). Results: A significant reduction in jump height on the DJ was observed in the Stretching (St) condition compared with the control condition (p = .001). Furthermore, these significant changes persisted in the dancers’ performance in the post-core condition (after performing the core exercises), with jump height being significantly lower for the EE group (p = .010). Conclusions: The dancer’s performance is immediately affected following 90-second EE per muscle group. After performing the centre exercises (prior to the allegro), the effects of the EE remained significant, continuing to reduce the vertical jump height for the DJ.
