AFONSO, José; MESQUITA, Isabel  and  MARCELINO, Rui. Study on contextual specifier variables of decision making in attack organization in female volleyball. Rev. Port. Cien. Desp. [online]. 2008, vol.8, n.1, pp.137-147. ISSN 1645-0523.

The contextual specifier variables of the match scenarios, interfere with the athletes’ tactical decision making, when attacking and blocking. This paper intended to explore the following variables: a) availability of the middle attacker for the quick attack; b) block movements previous to the set; c) block opposition, and also, study the relationships between the three variables, within the women’s Volleyball game. After validating the observation instrument (construct and content validation), we analyzed 472 sequences of attack and block, from 18 sets relative to a Classification Pool relating to the 2005 European Championships. The observation reliability was asserted through Kappa’s Reliability Index. The statistical procedures used were frequencies, percentages and Chi-Square. The main results show that: i) in more than half of the sequences, the middle attacker isn’t available for the quick attack; ii) before the set, the block tends to wait, instead of moving; iii) the double block is the most common, followed by individual block; iv) every relationship studied revealed a moderate degree of association. With this study it has been demonstrated that the availability of the middle attacker for the quick attack influences the actions of the opposite block in a decisive way, before and after the set.
