MOVEMENT BEHAVIOUR OF YOUNG VOLLEYBALL PLAYERS DURING THE BLOCK ACTION. IMPLICATIONS FOR TRAINING 

ABSTRACT

 

Objectives: The principal aim of this study was to examine movement behaviour of volleyball player during the block action in a in situ test. We examined differences between different destination of the ball, namely zone three and zone four in the volleyball court. Additionally we investigated key differences between successful and non successful performances.

Material and Methods: Thirty-two young volleyball players (mean age=17,38; SD=0,87) took part in this study. Volleyball players were required to block a ball to zone 3 and zone 4. The test was recorded by video and their movement behaviour was analyzed frame by frame. The experiment involved evaluating a total of 640 (320 per zone) attacking sequences. Four different groups were created in base of the performance (Successful, correct, mistake type I and mistake type II) and their temporal aspect were compared. Additionally, significant differences in the frequency of utilization of each type of execution and the average value of the temporal aspects of motion were observed, in function of the blocking zone.

Results. Most of the fails were caused by a time deficit, which produced uncertainty, and characterized by a too late start of the movement that did not permit to arrive at the right time to the attacking zone.

Conclusions. A successful block action requires initiate movement 100 ms after contact of the setter when the ball is attacked by Zone 4. Therefore, the relationship between the ball setter contains very valuable information to decide the area for the attack will occur favouring a subsequent motion control.
