Resumo
O objetivo deste estudo foi analisar as ações e seqüências de ações técnicas de jogadores e as estratégias de finalizações durante quatro partidas de futebol, a partir do tracking computacional. Foi utilizado o software Dvideow para a obtenção da posição dos jogadores em função do tempo e suas ações técnicas. De posse dos dados das ações dos jogadores, foram identificadas as ações e seqüências de ações realizadas e dados sobre as estratégias de finalizações utilizadas pelas equipes. Os resultados mostraram que a ação passe, e as seqüências de ações domínio?passe e domínio?condução?passe compreendem em média 89,5% das ações dos jogadores. Foram também as ações e seqüências de ações curtas as mais realizadas pelos jogadores no momento da finalização, além das cobranças de bola parada. Verificou-se que os atacantes foram os que mais realizaram seqüências de ações incompletas, enquanto os zagueiros foram os que menos realizaram. No entanto, os zagueiros foram os que mais desarmaram, enquanto que os atacantes foram os jogadores que mais finalizaram. Com relação às estratégias de finalizações, verificou-se que as equipes normalmente ganham a posse de bola em seu campo de defesa. Já o passe que antecede à finalização normalmente é executado no campo de ataque e possui até 20 metros. Os resultados também mostraram que as posses de bola que resultaram em finalizações envolvem poucos ou muitos passes e têm curta ou longa duração, dependendo da situação do jogo. Por fim, verificou-se que as finalizações ocorreram numa distância média de 21,02 metros. Assim, através desses resultados, conclui-se que jogadores normalmente realizam ações e seqüências de ações que envolvem poucos fundamentos e que as posses de bola que resultam em finalizações normalmente se iniciam no campo de defesa e podem envolver poucos ou muitos passes, e ter longa ou curta duração...

The purpose of this study was to analyze the technical actions, the sequence of actions and the shots to goal strategies during four soccer matches, through computational tracking. Software Dvideow was used to obtain data about players position and their technical actions. Then, it was identified the technical actions and sequence of actions performed by players and the shots to goal strategies. The results showed that the pass movement, and the Control?Pass and Control? Dribbling? Pass sequence of actions corresponded to 89,5% of the players actions. Shorts actions and sequences of actions are the most frequent movements performed by players in shots to goal too, besides the free kicks and penalty kicks. It was verified that forwards were the players who most performed incomplete sequence of actions, while defenders were the players that performed the lower number of them. Nevertheless, the defenders were the players that most performed tackles, while the forwards were the players who most performed shots to goal. About the shots strategies, it was verified that the teams usually win the ball possession in their defensive soccer field. The pass executed before the shots to goal frequently occurred in attack soccer field and it had up to 20 meters of size. The results also showed that ball possessions that resulted in shots to goal can involve few or great number of passes, and they have short or long duration, depending on the game situation. Finally, it was found that shots to goal occurred on a 22.02 meters average distance. So, it was concluded that: ... (Complete abstract, click electronic access below)
