    El objetivo de este estudio fue fijar las variables biomecánicas que más correlacionan con el rendimiento del salto de altura en función del grupo de edad. Se analizó el mejor salto de las finalistas en el campeonato nacional: 11 saltadoras de categoría cadete, nueve de categoría junior, y 12 de categoría senior. Se calcularon 25 variables de cada salto (fases de ante-salto, batida, y paso del listón). La técnica utilizada para analizar el salto fue la fotogrametría 3D empleando tres cámaras de vídeo (50 Hz). Se realizó un análisis descriptivo e inferencial (correlación lineal de Spearman). Las variables cinemáticas que correlacionan con el rendimiento son diferentes en cada grupo de edad, salvo la altura del CM sobre el listón. Los resultados parecen indicar que la forma de evaluar la técnica y los aspectos clave a considerar no son aplicables por igual a todas las categorías de edad.

    The purpose of this study was to establish the biomechanics variable of the high jump that are most highly correlated with performance in relation to age group. The best jump of 11 U-15 jumpers, nine U-18 jumpers, and 12 senior jumpers from their respective age group Spanish National Indoor Championship was recorded and analyzed. Twenty-five biomechanical variables were analyzed (pre-jump, take-off, and clearing the bar). The technique used to analyse the jumps as the 3D photogrammetric, using three video cameras (50HZ). A descriptive and inferential analysis of the data was done (Spearman correlation). The kinematic variables that correlate with performance are different for the different age groups, except the center of mass height on the bar. The results show that the evaluation and the key aspects of the technique should not be the same for the different age groups.
