Analysis of selected activities without the ball in volleyball by the specialized position of smasher
Kulasová, Kateřina ; Buchtel, Jaroslav (advisor) ; Vorálek, Rostislav (referee)
This bachelor thesis refers to game actions, without the ball, by the specialized position of smasher in top-rate volleyball. Situations are analysed from both offensive and defensive areas and they are considered until the moment of smasher's contact with the ball, or immediately afterwards. All situations mentioned above concern players of the first line that are smashing or defending the ball at the net. The analysis of such situations will be delivered on the basis of video sequences using the computer programme DartFish. In the first theoretical part the reader is familiarized with volleyball as a ball game itself, briefly introducing all individual game actions. Additional to this more information about the techniques of offensive striking and blocking is given. Finally, the knowledge of the smasher's properties and her role from the point of view of top- rate volleyball is described. The Research part analyses the individual motions of a smasher at the net who is not in contact with the ball. The analysis concerns the distances and speed at the time of movement, height of jumps, arms' distance while blocking and striking etc. Based on these analyses conclusions are made, where results are evaluated and compared in individual game situations. Key words: Defense, attack, block, smash,...

Knoblochová, Michaela ; Buchtel, Jaroslav (advisor) ; Vorálek, Rostislav (referee)
The bachelor thesis deals with activities of players especially blockers without ball, mainly in defence and to a lesser extent in offensive situations. These situations are analysed via selected sequences in the software DartFish. The first theoretical part introduces the reader generally to volleyball as a ball game. It characterises individual game activities whereas it is focused on blocking which is closely described in a separate chapter. The end of the theoretical part brings basic information about the specialised software used in volleyball - Datavolley, DartFish. The second research part analyses single activities and moves of a blocker without ball at the net first of all in defence and in lesser frequency in offence. It evaluates specific measurements of blocker's moves which have been taken via DartFish software on players in view. Based on the measurement results it recommends the most effective type of blocker's move considering distance. Key words: block, blocker's moves, somatic factors, game performance, volleyball rally, Datavolley, DartFish, defence, coverage
