Abstract

The aim of this research was to analyse the kinematic parameters and to ascertain the influence of those parameters on the pole vault result. The entity sample of the research consisted of successful vaults of 30 athletes, whose attempts were recorded at the European Junior Athletics Championships. The examinees performed the vaults as part of the qualification competition for the finale and the finale of the competition itself. The examinees were 17–19 years old, and the
range of their top results was from 4.90 to 5.30 m. The results of the regression analysis showed a significant influence of the predictor variables on the effective pole vault height. The centre of body mass height was mostly influenced by the following variables: TS – takeoff velocity, LSS – last step velocity, PSS – penultimate step velocity, TAPR – trunk angle at the moment of the pole release. The following variables had lesser, but still a significant influence: CBMDM – centre of body mass distance at the pole release moment, and MCMVV – time of pole straightening. Generally, the information gained by this research indicates the significant influence of the kinematic parameters on the pole vault result. Therefore, the conclusion is that the result efficacy in the pole vault is primarily determined by the variables defined by the motor capabilities, but also by the indicators determining the vault activity realization technique. The variables that define the body position during the pole release (trunk angle and centre of mass distance) have the most significant influence on the
vault performance technique, while the motor capabilities influence the last two run up steps velocity, take off speed and the time of pole straightening.
