O estudo teve como objetivo analisar a incidência temporal de gols em uma competição estadual e a relação do primeiro gol com o resultado final da partida em diferentes categorias. Foram analisadas 526 partidas das categorias sub-15, sub-17, sub-20 e profissional, de três competições estaduais de futebol do ano de 2018, realizadas no estado do Rio de Janeiro. A coleta dos dados foi feita a partir do site da Federação de Futebol do Estado do Rio de Janeiro. Foi realizada análise descritiva (média e desvio padrão) e o teste de Shapiro-Wilk para verificar a distribuição dos dados. Na comparação dos gols por intervalo de tempo, foram realizados os testes de Kruskal Wallis (distribuição não normal) e Anova (distribuição normal). Na relação do primeiro gol com o resultado final da partida, foi realizado o teste de Friedman para identificar a existência de diferença estatisticamente significativa entre os resultados da partida e o teste de Wilcoxon para verificar onde houve diferença. O valor de significância adotado foi de p
The present study aims to compare the tactical behavior of youth academy and professional players, in order to ascertain the contribution of full- and small-sided games for the development process. One hundred and eighty individuals were selected from three age groups (U-8, U-10 and U-12). A competition was held in which all teams faced each other once in each format (Full- and Small-Sided Games). In addition, 9 matches of the 2018 Brazilian Championship were analyzed. The paired t tests, Wilcoxon and Mann-Whitney tests was performed to the comparison between the tactical behavior of youth academy players in each game format with the professional players (p < 0.05). Youth academy matches generated more and shorter offensive sequences, interactions were less frequent and less variable, and players cooperated less with one another. In the small-sided game, specifically, there was a demand for ball circulation in terms of velocity and amplitude similar to that of professional matches. Elements were found that support the need to use small-sided games in training, as it provides similar stimuli to what players will find in the professional category in the future. The speed and width of ball circulation, a large number of shots on goal, and the constant exchanges of ball possession - which helps in the development of cooperative and oppositional relationships between the phases and moments of the game - are enough elements to sustain that the game settings discussed here are beneficial for player development.
