The aim of this study was to determine and confirm the influence and correlation of kinematic parameters on the success in shot put at top-level athletes with rotational technique. Research on this field to date showed many different kinematic parameters defining shot-put success, but more or less only those in the release phase. For this reason, the greatest interest in this work was to find out whether there exist the correlation and influence of kinematic factors on the results that are related to all phases of the shot. The study's model consists of 10 top-level putters with rotational technique competing at the 2008 European Cup Winter Throwing in Split. The recordings were made with two synchronised high-frequency cameras, and kinematic analysis was done with the APAS software. The results of the t test for independent samples showed statistically significant differences in arithmetic means between the elite and sub-elite throwers in six kinematic parameters. The calculation of Pearson's coefficient of correlation confirmed statistically significant correlation of nine kinematic parameters with the final result. With the use of linear regression we managed to explain 94.6 % of competitive success in a model, which included parameters that determine projectile motion. The model was statistically significant, as all the other models, except the one, which included kinematic parameters of the preparatory phase.
