RESUMO

The objective of this study was to develop a model for attack technical skills in zone four and to analyze the performance of young players through this model. In the first case, through the delphi method and in two distinct moments (1st and 2nd phases), fourteen coaches of the Brazilian male and female teams were interviewed. The structure of the model was designed in the first phase and, by means of consensus, the model itself was eventually designed in the second phase. Results evidenced that 170 attack technical skills were reported by the coaches in eleven block situations, and only four (SBT1-I, SBT1-J, SBT3-A e SBT3-S) did not reach the consensus level (mean, mode, median equal or above 4.0 and standard deviation 0,65). In the second case, twelve games were analyzed during the world championships in years 2005 and 2007 in the frequency and efficacy of actions. The results from the analysis of attack performances from zone four during the world championships showed a larger number in double blocks followed by simple and triple blocks. As for technical skills, the type of run with diagonal approach was the most used by attack players with the option of direct attack. Techniques where attack explores blocking were most common in compact double and triple blocks. The Spearman correlation analysis showed no relation between frequency and efficacy. However, a logistic regression analysis (binary and multinomial) between the most frequent techniques evidenced that SBD1-A block/skill situation was the most frequent but least likely to success. Technical skills in simple block situations were more likely to be successful than those in double blocks. The results also highlighted the situational aspect of attack that requires specific technical skills for certain block structures to be successful
