Resumo
O futebol é a modalidade esportiva de maior popularidade no mundo e apresenta uma característica complexa e multifatorial quanto ao desempenho. Desta forma, é crescente o interesse em entender os fatores que implicam no sucesso de uma equipe, gerando estudos que foram aumentando o conhecimento e a tecnologia, aplicados para a modalidade. O aspecto físico do jogo teve uma ampla atenção da literatura, principalmente em relação à velocidade máxima que os jogadores são capazes de executar em treinamentos e jogos. Para isso, houve um avanço do monitoramento dos jogadores com a introdução do GPS (Global Position System), caracterizando os esforços realizados pelos jogadores. O objetivo principal do estudo foi comparar a velocidade máxima realizada pelo jogador em testes de 30 metros e nos jogos oficiais, além de comparar a capacidade nas diferentes posições, em primeiro e segundo tempo de jogo, titulares e reservas da equipe; e resultado final de jogo, utilizando o GPS como instrumento de medição. Os resultados apresentados demonstraram que o GPS é um instrumento válido para mensuração da velocidade (r=0.94 em relação a uma fotocélula) e que as velocidades máximas (Km/h) atingidas nos jogos oficiais são superiores em relação aos testes de 30 metros (VMAXT - 34.2 ±1.55 vs VMAXJO - 35.5±2.17). Além disso, os atacantes alcançam maiores velocidades máximas no segundo tempo (VMAXP - 36.4±1.72 vs VMAXS - 34.8±0.91). Os reservas apresentam velocidades máximas menores, em relação aos titulares e em relação ao teste de 30 metros (VMAXTI – 35.4±2.21 vs VMAXRE – 31.5±2.86). Por fim, as velocidades máximas obtidas nas vitórias são maiores que nas derrotas (VMAXVIT – 34.8±2.29 vs VMAXDER – 33.1±2.56). A velocidade se apresentou como uma capacidade importante para o sucesso de uma equipe, principalmente quando os atacantes realizam ações de velocidade máxima, apontando a necessidade de maiores estudos e atenção a esta variável de treinamento.
Soccer is the most popular sport in the world and presents a complex and multifactorial characteristic in terms of performance. Thus, there is a growing interest in understanding the factors that imply the success of a team. Studies that increased knowledge and technology about the modality. The physical aspect of the game has received wide attention in the literature, mainly in relation to the maximum speed that players are able to perform in training and games. For this, there was an advance in the monitoring of players with the introduction of GPS (Global Position System) characterizing the efforts made by players. The main objective of the study was to compare the maximum speed performed by the player in the 30-meter tests and in the official games, in addition to comparing the capacity in the different positions, in the first and second half, holders and reserves and final game result, using as assessment the GPS as measuring instrument. The results presented showed that the GPS is a valid instrument for measuring speed (r=0.94 in relation to a photocell) and that the maximum speeds (Km/h) reached in the official games are superior in relation to the 30 meters tests (VMAXT - 34.2 ±1.55 vs VMAXJO - 35.5±2.17), in addition the fowards reach higher maximums in the second halftime (VMAXP - 36.4±1.72 vs VMAXS - 34.8±0.91). Non starters players have lower maximum speeds in relation to the starters athletes, and in relation to the 30-meter test (VMAXTI – 35.4±2.21 vs VMAXRE – 31.5±2.86). Finally, the maximum speeds obtained in wins are higher than in losses (VMAXVIT – 34.8±2.29 vs VMAXDER – 33.1±2.56). Speed was presented as an important ability for the success of a team, especially when fowards perform maximum speed actions, pointing the need of increasing studies and attention to this training variable aspect.
