Vliv kinematických faktorů na rychlost a přesnost střelby v házené. / The influence of kinematic factors on shooting velocity and accuracy in team handball

Šetelík, Martin January 2014 (has links)
Title: The influence of kinematic factors on shooting velocity and accuracy in team handball. Goals: The main goal of this thesis is to find the influence of kinematic factors of throwing arm on shooting velocity and accuracy in team handball. Methods: The relationship between velocity and accuracy is based on practical measurement of group of team handballers. The measurement itself consists of three chosen types of shooting. We focused on movement and reciprocal position of reference points (ball, wrist, elbow and shoulder joint) and their influence on velocity and accuracy of hitting a target in goal. For measuring velocity is used a radar device Stalker. Measured values were elaborated in TEMA motion program which is appropriate for detail 3D analysis of throwing motion. Results: The results of this thesis demostrate the proximal-to-distal sequence in both types of throwing. An absolute velocities in this sequence were higher at Vmax shots than in accurate shots. There was found a significal difference between elbow extension angle of shots on upper and lower targets but exception. Higher elbow extension angle was found at Vmax shots than at accurate shots. This shows the influence of angle size on shooting velocity. A movement of the arm relative to vertical axis of a goal reflected an...
