Resumen

El wushu, comúnmente conocido como kung-fu, es un deporte exigente que requiere una rápida aplicación de fuerza para alcanzar alturas significativas en los saltos verticales. Estos saltos son fundamentales para ejecutar tareas aéreas complejas y obtener puntuaciones más altas en las competiciones. Objetivo: El objetivo de este estudio fue establecer datos normativos para los parámetros de rendimiento del salto con contramovimiento (CMJ) en atletas de élite de wushu. Métodos: Se implementó un diseño transversal en la competición de wushu de los Juegos de Malasia 2022 (SUKMA) con 115 atletas (67 hombres). Cada atleta realizó tres CMJ con las manos en la cintura sobre un par de plataformas de fuerza. Los datos de rendimiento y biomecánicos (altura del salto vertical, potencia propulsiva relativa máxima, fuerza propulsiva relativa máxima, índice de fuerza reactiva modificado e impulso propulsivo relativo neto) se recopilaron utilizando el software Hawkins Dynamics. Se utilizó un ANCOVA para comparar los parámetros del CMJ entre sexos y eventos, controlando la edad y la masa corporal. Los datos normativos se establecieron utilizando puntuaciones t. Resultados: El ANCOVA indicó que las variables del CMJ y biomecánicas diferían según el sexo y la edad (p<0,01), pero no según la prueba. Conclusión: Estos valores normativos proporcionan una base para comprender el rendimiento del CMJ en atletas de élite de wushu y pueden orientar la exploración ulterior de las adaptaciones del entrenamiento, la evaluación del riesgo de lesiones y la optimización del rendimiento. Sin embargo, se necesitan más investigaciones para validar y ampliar plenamente las posibles aplicaciones prácticas de estos hallazgos.
