Resumen

Entre 2012 y 2026, las reglas de competición del taekwondo experimentaron profundas transformaciones, impulsadas por la necesidad de tener una mayor transparencia y aumentar el atractivo para los espectadores. Este estudio analiza la evolución normativa del taekwondo y su impacto en la dinámica de los combates y en el rendimiento. Para ello, se revisaron documentos oficiales de World Taekwondo y literatura científica con el fin de sintetizar los cambios en el sistema de puntuación, la tecnología utilizada y la estructura de los combates. Los principales resultados muestran que esta evolución estuvo marcada por la implementación progresiva del Sistema Electrónico de Puntuación (Protector Scoring System – PSS), que pasó del uso exclusivo en el peto en 2012 a la incorporación de sensores en el casco y en los calcetines en 2017. La reforma de 2022 introdujo el sistema “al mejor de tres”, reiniciando la puntuación en cada asalto y estableciendo un límite de cinco gam-jeom (penalizaciones) por asalto. En 2026 se incorporaron guantes con sensores para los golpes de puño y una “Zona de Advertencia” de 60 cm para el control espacial. Las reformas del sistema de puntuación aumentaron el valor de técnicas complejas, como la patada giratoria a la cabeza, que pasó a puntuar seis puntos en 2026. El sistema de penalizaciones evolucionó desde un límite de diez para la descalificación (2017) hasta la pérdida automática del asalto al alcanzar cinco penalizaciones (2022). Los cambios estructurales incluyeron la adopción de áreas octogonales y la simplificación del la Repetición Inmediata de Video, eliminando la revisión de patadas a la cabeza cuando se utiliza el PSS (2026). La literatura científica indica que estos cambios incrementaron la intensidad de los combates, con estudios que reportan mayores niveles de lactato postcombate y mayores exigencias cinemáticas, obligando a los atletas a adoptar estrategias técnico-tácticas más ofensivas. En conclusión, la evolución normativa ha modernizado el taekwondo, convirtiéndolo en un deporte más dinámico, tecnológicamente avanzado y físicamente exigente. La adopción de la puntuación independiente por asalto y las actualizaciones de 2026 priorizan el rendimiento explosivo y la claridad para el público, lo que exige que los protocolos de entrenamiento se adapten a las mayores demandas anaeróbicas y estratégicas.
