Abstract


The basic aim of this research was to determine the differences of kinematic parameters in two qualitatively different groups of young pole vaulters. With this purpose, a research was conducted in which the video records from a competition were acquired. The sample of entities (n=71) consisted of successful vaults of 30 pole vaulters, whose attempts were recorded at the European Junior Championship in Novi Sad, held on 23-26th July 2009. The examinees performed the vaults as a part of the elimination competition for the finals, and during the final part of the competition. The age of examinees was from 17 to 19 years, and the span of their best results was from 4.70 to 5.30 meters. The kinematic analysis was conducted according to the standards of APAS procedure (Ariel Performance Analysis System, USA), determining 25 kinematic variables necessary for further analysis. The entities (vaults) were divided into two categories (qualitative classes) based on the expert knowledge. Group 1 consisted of successful vaults up to 4.90 m (n=46), while group 2 consisted of successful vaults whose height was more than 4.90 m (n=25). The discrimination analysis determined the parameters differentiating the vaults of different quantitative classes. Also, it was confirmed that the result efficiency in pole vault was primarily determined by the variables defined by motor abilities, as well as the indicators determining the vault performance technique.
