The influence of kinematic factors on shooting velocity and accuracy in team handball
 Šetelík, Martin ; Tůma, Martin (advisor) ; Malý, Tomáš (referee)
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...

A relationship between velocity and accuracy of chosen type of shooting in teamhandball
 Šetelík, Martin ; Tůma, Martin (advisor) ; Pravečková, Petra (referee)
Title: A relationship between velocity and accuracy of chosen type of shooting in team- handball Goals: The goal of this thesis is finding of relationship between velocity and accuracy of team handball throws because these factors influence the number of scored goals which arbitrate about results of each match. Methods: The thesis is divided into 2 parts: theoretic which putts together actual knowledge about this topic and and practical part which presents practical measurement and its results. Study of relationship between velocity and accuracy is based on practical measurement of chosen group of team handballers. The measurement itself consists of four chosen types of shots. We studied velocity of shots and their accuracy during shooting on selected places. For measuring velocity is used radar device Stalker. Measured values were statistically elaborated in programs Microsoft Excel 2007 and Statistica. Results: The results of this thesis demostrate relatively high relationship between velocity and accuracy. Accurate throws (60 and more percent succesful trys) reached velocity equal to 95% of maximal velocity. This velocity was the average of five throws with a maximum exertion to achieve maximal speed. Key words : team handball - shooting velocity - shooting accuracy
