          Abstract

          Abstract Declarative Tactical Knowledge Tests are presented as important evaluation tools for the teaching-learning-training process regulation. This study aimed to establish the content validity of scenes of the Declarative Tactical Knowledge Test in Volleyball – DTKT:Vb. Five male coaches of the Brazilian Volleyball team who worked with male athletes participated as judges, being responsible for training formation categories up to 21 years, experts in the sport, with minimum ten years of experience. The judges evaluated 212 scenes containing extremity attack (n=55), central attack (n=33), setting (n=68) and block (n=60) situations and used a 1-5 point likert scale to assign a score to the scene according to requisites image clarity, practical relevance and item representativity. The Content Validity Coefficient (CVC) was used to determine the CVC for each scene and the instrument as a whole, with cutoff point of 0.80. The results demonstrated that “image clarity” (CVC=0.92), “practical relevance” (CVC=0.96) and “item representativity” criteria (CVC=0.96) showed satisfactory levels. After calculating CVC, the ecological validity of scenes was determined, which consists of the selection of scenes where there was convergence among decision made by judges and decision made by athletes. Thus, from 212 scenes initially prepared, 66 have been validated. Scenes validated using CVC enabled the evaluation of the Declarative Tactical Knowledge, assisting in the planning of teaching-learning-training processes of male volleyball athletes.

          Resumo Os testes de conhecimento tático declarativo apresentam-se como procedimentos avaliativos importantes para a regulação do processo de ensino-aprendizagem-treinamento. Objetivou-se estabelecer a validade de conteúdo das cenas do teste de conhecimento tático declarativo no voleibol – TCTD:Vb. Participaram como juízes cinco treinadores masculinos da seleção brasileira de voleibol que trabalharam com atletas do sexo masculino, sendo responsáveis pelas categorias de formação até 21 anos, peritos na modalidade, com experiência mínima de dez anos na mesma. Os juízes avaliaram 212 cenas contendo situações de ataque de extremidade (n=55), ataque de central (n=33), levantamento (n=68) e bloqueio (n=60) e utilizaram uma escala tipo likert de 1 a 5 pontos para atribuir uma nota para cada cena nos quesitos clareza de imagem, pertinência prática e representatividade do item. Recorreu-se ao coeficiente de validade de conteúdo (CVC) para determinar o CVC para cada cena e do instrumento como um todo, sendo o ponto de corte 0,80. Os resultados demonstraram que os critérios “clareza de imagem” (CVC=0,92), “pertinência prática” (CVC=0,96) e “representatividade do item” (CVC=0,96) apresentaram níveis satisfatórios. Após o cálculo do CVC, determinou-se a validade ecológica das cenas, que consiste na seleção das cenas em que houve convergência entre a decisão apontada pelos juízes e decisão tomada pelo atleta. Desta forma, a partir das 212 cenas inicialmente elaboradas, 66 cenas foram validadas. As cenas validadas por meio do CVC possibilitam a avaliação do conhecimento tático declarativo auxiliando no planejamento dos processos de ensino-aprendizagem-treinamento de atletas de voleibol masculino.

            Relation of knowledge and performance in boys' tennis: age and expertise.

            This research examined boys' development of knowledge structure and sport performance in tennis. To assess decision-making and performance, expert and novice tennis players (10-11 and 12-13 years old) were compared on tennis performance (control, decision, and execution), tennis knowledge, serve skill, and groundstroke skill. Experts regardless of age performed better than novices on tennis skill and knowledge; experts' decisions and actions were better during tennis game performance. Declarative knowledge was related to the development of procedural knowledge; serve and groundstroke skill were related to the motor execution components of performance. Interviews during and after game play were used to examine knowledge and decision-making. Experts, as compared to novices, focused on higher level concepts, had more connections between concepts, and had more condition and alternative action concepts that were important to the game's goal structure. Experts' greater decision-making ability during game play was related to their knowledge structure.

              The effect of deliberate play on tactical performance in basketball.

              This field-based study analyzed effects of a deliberate-play training program in basketball on tactical game intelligence and tactical creativity. 22 youth basketball players, ages 10 to 12 years, completed basketball training in one of two equal-sized groups. The deliberate-play training program contained unstructured game forms in basketball. The placebo group played in traditional structured basketball game forms. Tactical intelligence and creativity was assessed before and after an 18-lesson intervention. Analysis showed significant training improvement only for the deliberate-play group. In addition, this outperformance of the placebo group was not only observed for tactical creativity but also for tactical intelligence.
