Abstract
El objetivo del presente estudio fue describir y comparar el patrón de movimiento de escaladores de diferente Nivel deportivo durante la técnica de lanzamiento. La muestra estuvo compuesta por 10 escaladores, 5 de alto nivel y 5 de bajo nivel. Se midieron variables cinemáticas de posición, velocidad y aceleración de diferentes segmentos corporales. Se utilizó un modelo anatómico de 23 puntos y el software KINESCAN del IBV para digitalizar el patrón de movimiento. El MANOVA realizado mostró diferencias según Nivel deportivo en ciertas variables cinemáticas. Específicamente, el grupo de mayor nivel obtuvo mayor velocidad del centro de masas, cadera y codos durante la fase de impulso. Los resultados obtenidos sugieren que la destreza en la técnica permitió generar movimientos más rápidos en determinados segmentos corporales a fin de alcanzar una presa del rocódromo dispuesta a una altura superior a la posición inicial del escalador.
