Abstract

Objetivo: Associar o saque com a defesa e o contra-ataque, e a defesa com o contra-ataque, de acordo com o sucesso no set em equipes femininas de base. Materiais e métodos: Foram analisadas 2960 ações de 16 jogos, sendo 1611 saques, 870 defesas e 479 contra-ataques. A associação foi verificada através do teste Qui-quadrado. Resultados e discussão: O saque mostrou-se associado à defesa no set vencido e perdido (X2= 83.938, p< 0,000; X2=123,473, p< 0,000, respectivamente), entre o saque e o contra-ataque, não houve associação no set vencido (X2= 15,071, p= 0,058), no entanto houve associação no set perdido (X2= 17,844, p= 0,022). A defesa associou-se ao contra-ataque, tanto no set vencido (X2= 65,644, p<0,001) quanto no perdido (X2= 57,886, p<0,001), além disso, as defesas excelentes apresentaram frequência mais do que o esperado de pontos, apenas no set vencido (3,7). Conclusão: O saque parece ser um elemento norteador para a construção da organização defensiva das equipes independente do resultado do set, enquanto que, a qualidade da defesa aumenta as possibilidades de conquista de pontos de contra-ataque.
