Resumo
O objectivo deste estudo baseou-se na determinação do comportamento técnico-táctico, individual e colectivo, e a variação da FC em jogos reduzidos 6x6 condicionados aos constrangimentos do número de balizas.
Foram analisados 12 jogadores com idade média 12,4 ± 0,5 anos, correspondendo ao escalão de infantis (sub-13). Estes tinham em média 4,6 ± 1,2 anos de prática da modalidade.
Os JR tiveram a duração de 12 minutos, seguidos de um momento de recuperação, num espaço de jogo 60x40m. Em cada jogo foi registada a FC 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 da ANOVA de Friedman. Nos casos onde foram verificadas diferenças, foi utilizado o teste de wilcoxon para as descriminar.
Os valores da FC foram analisados através de um modelo de análise de variância factorial para medidas repetidas 3x4 (exercício: Gr6x6Gr sobre uma baliza, Gr6x6Gr sobre duas balizas, 6x6 com o objectivo de chegar com a bola a uma zona alvo; zonas de FC: 1, 2, 3, 4).
O cálculo estatístico foi realizado através do software de tratamento estatístico SPSS para Windows, versão 16.0 (SPSS Inc., Chicago, IL) e a significância estatística foi mantida em 5%
Na análise dos ITTI verificamos diferenças significativas no número de remates do JR1 para o JR2, e no número de intercepções do JR1 para o JR3 e do JR2 para o JR3.
Em relação aos ITTC, existem diferenças significativas entre o JR2 e o JR3, particularmente na duração das jogadas, no número de jogadores envolvidos e no número de passes.
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 JR1 e a menos intensa foi registada no JR3.
A intensidade dos JR intercalou momentos de grande esforço com períodos de menor intensidade.
The purpose of this study was based on determining the technical and tactical behavior, individually and collectively, and HR variation in reduced 6x6 games conditioned the constraints on the number of goals. We analyzed 12 players with a mean age 12.4 ± 0.5 years, corresponding to the rank of children (sub-13). These were on average 4.6 ± 1.2 years of practice mode. The RG lasted 12 minutes, followed by a moment of recovery, an area of 60x40m game. In each game was recorded HR of each player and made the film for consequent analysis of technical and tactical actions. We conducted a descriptive analysis of all data. The inferential statistics of the data was performed by ANOVA Friedman. In cases where differences were found, we used the Wilcoxon test to discriminate. The HR values were analyzed using a standard analysis of variance for repeated measures factorial 3x4 (exercise: Gr6x6Gr on one goal, two goals on Gr6x6Gr, 6x6 in order to get the ball to a target zone, areas of HR: 1, 2, 3, 4). The statistical calculation was performed using the statistical software SPSS for Windows, version 16.0 (SPSS Inc., Chicago, IL) and statistical significance was maintained at 5%. In the analysis of ITTI found significant differences in the number of shots for the RG1 to RG2, and the number of interceptions for the RG1 to RG3, and RG2 to RG3. In relation to the ITTC, there are significant differences between RG2 and RG3, particularly in the duration of moves, the number of players involved and the number of passes. During the RG, the HR of the players was situated much of their time above the 90.0% of HR Max's. The most intense situation of game was RG1 and less intense was registered in RG3. The intensity of RG interspersed moments of great stress with periods of lower intensity.
