O objetivo deste estudo centrou-se na análise e comparação do comportamento coletivo das equipas de futebol de alto rendimento em situações de canto com diferentes níveis de sucesso.
Foram analisadas 71 situações de canto, registadas em oito jogos do Manchester City realizados na English Premier League na época de 2010/2011.
O comportamento coletivo, caracterizado por variáveis posicionais, foi analisado em função do resultado da situação de canto e das variáveis contextuais (local do jogo, qualidade do adversário e resultado corrente).
Os dados posicionais (2D) dos jogadores foram recolhidos através do sistema de rastreamento ProZone®, as variáveis coletivas foram calculadas no MATLAB. A ANOVA de design misto de medidas repetidas foi utilizada para analisar e comparar o comportamento espaço-temporal dos jogadores.
Os resultados demonstraram que nos cantos bem sucedidos, realizados contra adversários do mesmo nível, a distância entre o atacante e defesa mais próximo foi significativamente superior nos momentos de início da corrida e do pontapé, comparativamente com pontapés que terminam com a interceção do adversário.
Nas situações em que o avançado ganhou a bola o ângulo entre atacante, defensor e centro da baliza foi significativamente superior, comparativamente com pontapés que terminaram com a interceção do adversário, no momento de início da corrida.
ABSTRACT : This study aimed to analyze and compare the collective behavior of high performance football teams in corner kicks with different levels of success. The sample consisted of 71 corner situations registered in eight games of Manchester City, played in English Premier League in 2010/2011 season. Collective behavior, characterized by positional variables, was analysed according to the corner kick outcome and contextual variables (game location, quality of opposition and match status) Positional data (2D) of the players were collected using the tracking system ProZone®, the collective variables were calculated in MATLAB software. A mixed design ANOVA for repeated measures was used to analyze and compare the players’ space-time behavior. The results suggest that in successful corner kicks, performed against opponents of the same level, the distance between the attacker and nearest defender was significantly higher at the start of attacker movement and of kick compared with corner kicks that ended with the ball interception by opponents. In situations where the attacker won the ball, the angle between the attacker, defender and the goal center was significantly higher, comparatively to the corner kicks that ended with the ball interception by opponents, at the start of attacker movement.
