O objetivo do presente estudo foi identificar as variáveis notacionais e variáveis posicionais que se associam ao sucesso das equipas dos três escalões de formação (Sub-16, Sub-17 e Sub-19) em jogos reduzidos de futebol (5+GR vs. 5+GR). A amostra foi constituída por 36 jovens jogadores. Cada escalão foi dividido em duas equipas que jogaram 8 minutos. Para registo dos dados foi desenvolvido um sistema de observação constituído por variáveis notacionais ofensivas (simples e compostas) e defensivas, e por quatro variáveis posicionais coletivas (área de superfície, índice de dispersão, comprimento da equipa e largura da equipa) registadas no ataque e defesa.
Os resultados do teste de Mann-Whitney demonstraram as variáveis Número de passes, Número de contatos com a bola, Ritmo de intervenção sobre a bola, Ritmo de transmissão da bola e o Número de passes/Número de jogadores intervenientes variam significativamente em função do sucesso das sequências ofensivas no escalão Sub-16. O teste ANOVA revelou que a variável posicional Comprimento da equipa está relacionada com o sucesso das sequências ofensivas nos três escalões etários. Ficou confirmado que o comportamento das equipas em campo e os fatores que influenciam o sucesso ofensivo e defensivo variam em função da idade e experiência dos praticantes.
The purpose of this study was to identify the notational variables and positional variables associated with the success of the teams of three age groups (U16, U17 and U19) in small-sided games (5 + GK vs. 5 + GK). The sample consisted of 36 young players. Each age group was divided into two teams that played 8 minutes. To record the data, an observation system was developed consisting of offensive (simple and compound) and defensive variables, and four collective positional variables (surface area, stretch index, team length and team width) registered in the attack and defense. The results of the Mann-Whitney test showed that the variables Number of passes, number of touches, rhythm of intervention on the ball, rhythm of transmission of the ball and number of passes / number of players involved vary significantly according on success of the offensive sequences at the U16 age group. The ANOVA test revealed that the positional variable Team length is related to the success of the offensive sequences in the three age groups. It was confirmed that the behaviour of the teams on the field and the factors that influence the offensive and defensive success vary according to the age and experience of the practitioners.
