Qualitative description of the ideal Yurchenko layout vault technique


ABSTRACT
The Yurchenko vault was first pioneers in 1982 by Natialie Yurchenko and has since become the most widely used vault entry for women as well being performed by men. The aim of this paper is to examine the available literature and provide a detailed description of the key biomechanics characteristics and their interrelationship in the possibly ideal technique for a Yurchenko layout vault. Current scientific literature has identified several biomechanical characteristic that are shared among outstanding performances: a) a quick and close to vertical take-off from the springboard following the round-off, b) very fast rotation backward onto the table, with a high angle of attack between 30-40° c) a very short table support phase with an increasing vertical velocity on take-off with minimal losses in horizontal velocity, with the best predictive variable to a successful vault being angular momentum on departure from the springboard. Coaches who wish to improve their gymnast’s performance can compare their gymnast’s technique to the available data and devise training protocols to address their gymnast’s short comings based on comparisons with the proposed ideal kinematics. Coaches should also concentrate on developing the gymnast’s ability to generate and maintain angular momentum throughout the Round-off, pre-flight phase and table impact as these are the most technically challenging phases of the vault and also associated with as successful execution of this vault.
