Zakladni kinematicke rozdily mezi dvima technikami strelby z vyskoku v hazene
(Grundlegende kinematische Unterschiede zwischen zwei Typen von Sprungwürfen im Handball)
The aim of this study is to identify differences in some basic kinematic parameters between two different jump shot (JS) techniques used in handball. Ten male top-level handball players executed six JS (three shots using each technique). Among all attempts, we chose two JS for all players, the most characteristic for each technique, for further analysis. Two SVHS Video cameras operating at 25 frames per second were used for the acquisition of the data. Data processing was performed by APAS (Ariel Performance Analyses System). Basic statistics for variables were computed, and the t-test for paired samples was used to assess statistical significance differences between kinematic variables. Many similarities and differences between both shots were found. Most interesting are the following characteristics: almost all parameters of approach show that the efficiency of the approach in the last step was better in jump shots where the take-off leg is opposite the throwing hand (JS1); the body centre of gravity in JS2 (the take-off leg is on the same side as the hand with which the players are shooting) before the throw moved forward significantly more than the body centre of gravity by JS1; in JS1 the height of the throw was significantly greater than in JS2; the angle between the shoulder axis and the horizontal axis in the sagittal plane at the end of the take-off was significantly greater in JS1. The angle in the hip axis was significantly greater in JS2; landing in JS1 was mostly made with the take-off leg (left leg) while in JS2 it was made with the opposite leg (left leg).
