Resumo
O objectivo deste estudo foi analisar os efeitos da manipulação do número de balizas sobre as acções técnico-tácticas, individuais e colectivas, bem como na variação da FC e da PSE em diferentes JR de futebol (GR+6x6+GR sobre uma baliza; GR+6x6+GR sobre duas balizas; e 6x6 com ataque a uma zona alvo) em jogadores Sub-15 de alto nível.
Participaram 12 jogadores, com idade de 14.3±0.5 anos, altura 1.74±0.03 cm, peso 66.5±3.7 kg e com 5.1±1.4 anos de prática de futebol. Os JR tiveram a duração de 12 minutos com recuperação passiva num espaço de jogo 60x40m. Em cada jogo foi registada a FC e a PSE de cada jogador e efectuada a filmagem para posterior análise das acções técnico-tácticas.
Realizou-se uma análise descritiva de todos os dados. A estatística inferencial dos dados foi realizada através de comparações efectuadas com o teste de Friedman, Wilcoxon e ANOVA para medidas repetidas. Para tratamento dos dados foi utilizado o software Statistical Package for the Social Sciences (SPSS versão 16.0), sendo estabelecido um nível de significância de 5%.
Apesar da maior parte dos gestos técnicos e das acções ofensivas manterem um nível de eficácia igual, registamos diferenças significativas nas seguintes acções, passes certos, situações de 1x1.
. Durante os JR, a FC dos jogadores situou-se grande parte do tempo acima dos 90,0% da FC Max, a situação de jogo mais intensa foi a do JR2, formato utilizado com duas balizas. A PSE aumentou o seu valor com o desenvolvimento dos JR, sendo o JR3 foi percepcionado como o mais intenso pelos jogadores. Estes resultados permitiram concluir que a manipulação do número de balizas cria diferenças nas situações de confronto, nomeadamente 1x1 e intercepções. A intensidade dos JR intercalou momentos de grande esforço com períodos de menor intensidade. A PSE em colaboração com a monitorização pode funcionar como um bom indicador da intensidade do esforço.
The purpose of this study was to analyze the effects of manipulating the number of goals on the individual and collective technical and tactical action, the variability of HR and RPE at different small-sided soccer games (goalkeeper+6x6+goalkeeper on one goal, goalkeeper+6x6+goalkeeper on two goals, and 6x6 to attack a target zone) under-15 players in high level. 12 players participated, aged 14.3± 0.5years, height 1.74±0.03 cm, weight 66.5±3.7 kg and 5.1±1.4 years of soccer practice. The small-sided games lasted 12 minutes with passive recovery in an area of 60x40m game. In each game was recorded HR and RPE of each player and made the film for subsequent analysis of technical and tactical actions. We conducted a descriptive analysis of all data. The inferential statistics of the data was realized through comparisons with the Friedman, Wilcoxon and ANOVA for repeated measures. The data collected was used Statistical Package for Social Sciences (SPSS version 16.0), setting a significance level of 5%. Although most of the technical abilities and offensive actions to maintain a level of equal efficacyWe registered significant differences in the following actions, right passes,1x1 situations. During the small-sided game’s, the player’s HR Max was, most of the time, above the HR Max’s 90,0%, the most intense game situation was the small-sided game 2, format used with two goals. The PSE increased its value with the small-sided game’s development, being small-sided game 3 perceived as the most intense by the players. These results allowed to conclude that the manipulation of the goals number creates differences on the showdown’s situations, namely 1x1 and interceptions . The intensity of small-sided games interspersed moments of great stress with periods of lower intensity. The PSE in collaboration with the monitoring can serve as a good indicator of the intensity of effort.
