Abstract(s)
As situações de bola parada têm vindo a assumir uma relevância cada vez mais significativa
no jogo de futebol, muito em particular as situações de canto, definindo frequentemente os
vencedores dos jogos. O objetivo deste estudo foi analisar, visando compreender, a
organização defensiva em situações de canto no futebol. Depois de definidos os indicadores e
variáveis para a análise desta situação, aplicámos o instrumento construído para o efeito
(ficha de registo e campograma) aos últimos 16 jogos do Campeonato do Mundo de Futebol de
2018. Foram analisados um total de 139 pontapés de canto. Através de uma metodologia
observacional foram analisados e quantificados os seguintes critérios: a) Tempo de Jogo; b)
Resultado; c) Organização Defensiva; d) Zonas de Organização Defensiva Inicial; e) Zonas de
Organização Ofensiva Inicial; f) Zonas de Organização Defensiva ao 1º Toque na Bola; g) Zonas
de Organização Ofensiva ao 1º Toque na Bola; h) Pé do Marcador; i) 1ª Bola da Defesa; j) 1ª
Bola do Ataque; l) Zona do 1º Toque na Bola; m) Resultado do Canto; n) Tempo Total do
Canto; o) Tempo em que o 1º Atacante Inicia o Movimento; p) Tempo em que o 1º Defesa
Inicia o Movimento; q) Tempo do Batedor do Canto; r) Tempo da Bola no Canto até ser Tocada
pelo 1º Jogador e s) Trajetória da Bola. Os dados recolhidos indicam que o tipo de
organização defensiva mais comumente utilizado foi a Defesa Mista – Dominância Individual
(79,9%), seguida da Defesa Mista – Dominância Zonal (15,1%) e com a Defesa Individual (3,6%)
e a Defesa à Zona (1,4%) a serem utilizadas com menos frequência. Os resultados obtidos
mostraram ainda uma ocupação preferencial dos defensores na zona central da baliza entre
áreas e do poste mais próximo da marcação do canto, quer antes do canto ser marcado (57,5%
e 15,3% dos jogadores respetivamente), quer no momento do 1º toque na bola após a
marcação do canto (52,6% e 16,4% dos jogadores respetivamente), bem como que os
jogadores defensores tendem a reagir à ação dos adversários iniciando o seu movimento
frequentemente 0,36s depois dos atacantes. Estas variáveis e instrumento desenvolvido
parecem ser relevantes e úteis para compreender e melhorar o desempenho defensivo das
equipas de futebol nas situações de pontapé de canto, quer por investigadores, quer por
treinadores e equipas técnicas de futebol.
Set pieces have become increasingly important in football, particularly corner situations, often defining match winners. The objective of this study was to analyze, aiming to understand, the defensive organization in corner situations in football. After defining the indicators and variables for this situation, we’ve applied a specific built instrument (record sheet and campogram) to analyze the last 16 matches of the 2018 FIFA World Cup. A total of 139 corner kicks were analyzed. Through an observational methodology the following criteria were analyzed and quantified: a) Match Time; b) Result; c) Defensive Organization; d) Initial Defensive Organization Zones; e) Initial Offensive Organization Zones; f) Defensive Organization Zones at 1st Touch on the Ball; g) Areas of Offensive Organization at the First Touch on the Ball; h) Corner Marker Foot; i) 1st Defense Ball; j) 1st Attack Ball; l) 1st Ball Touch Zone; m) Corner Result; n) Total Corner Time; o) Time at which the First Attacker Begins the Movement; p) Time at which the First Defender Begins the Movement; q) Corner Marker Time; r) Time of the Ball in the Corner until Touched by 1st Player and s) Ball Trajectory. The data collected indicate that the most commonly used type of defensive organization was Mixed Defense - Individual Dominance (79.9%), followed by Mixed Defense - Zonal Dominance (15.1%) and Individual Defense (3.6%) and Zone Defense (1.4%) to be used less frequently. The results also showed a preferred occupancy of defenders in the central area between goal and the closest corner post, either before the corner was scored (57.5% and 15.3% of the players respectively) or on the 1st touch of the ball after the corner is scored (52.6% and 16.4% of the players respectively), as well as the defending players tend to react to the opponents' action by starting their movement 0.36s after the attackers. These variables and developed instrument appear to be relevant and useful for understanding and improving the defensive performance of football teams in corner kick situations either to researchers, to managers, football coaches and technical staff.
