ABSTRACT
Introduction: Creativity is a recognized quality in various areas, including sports. Within the training processes, various modifications to objectives, game configurations, rules, among other factors, can be considered to favor creative solutions to the tactical problems inherent to soccer. This systematic review aimed to identify the impact of the number of players on the emergence of creative movements in small-sided soccer games, emphasizing deliberate practice. Methods: A systematic review of Scopus, PubMed, Scielo, PsycInfo, SportDiscus and Lilacs databases was performed according to PRISMA guidelines. Eligibility criteria were defined based on the elements of population, context and concept. Only full articles published in scientific journals written in English were included. No period restriction was applied. Results: Five papers were included and the results of studies indicate greater number of actions, variability, and creativity in small-sided games compared to formal soccer matches. When comparing different small-sided game formats, 5 v 5 showed higher values in terms of total number of actions compared to 7 v 7, and the absolute number of original and creative actions tended to decrease as the game format increased. Imbalanced small-sided games format can promote increased exploratory behavior. Structural manipulation in goal positioning in 5 v 5 games may also influence the originality of tactical behaviors, while the use of different ball types in 4 v 4 games appears to decrease fluency values. In 6 v 6 games, fluency and versatility are negatively impacted. Conclusion: Reduced game formats with fewer players and in smaller field dimensions provide more suggestive environment for exploratory behavior, variability and original and creative actions.

ABSTRACT
Abstract The study aimed to analyze the core tactical offensive principles and technical efficiency of primary school futsal players. Thirty-three students from a school in Paraná participated in the study. The System of Tactical Assessment in Soccer (FUT-SAT) and the System of Notational Analysis in Small-sided Soccer Games were used for tactical-technical analysis. It was found that the tactical principle "offensive coverage" was most frequently executed by the primary school futsal players (p = 0.01), followed by "width and length" without ball (p < 0.01). Moderate and strong significant correlations were identified between the execution frequency of the core tactical principles "penetration", "offensive coverage", "width and length without ball", "offensive unity" and efficiency in technical skills (from r = 0.43 to r = 0.82, p < 0.05). It is concluded that there is a model of playing near the game center in the presented age group, and that the efficiency of executing technical skills is associated with tactical behavior in game situation.
Resumo O estudo objetivou analisar os princípios táticos fundamentais ofensivos e a eficácia técnica de escolares praticantes de futsal. Participaram do estudo 33 alunos de uma escola no Paraná. Utilizou-se o Sistema de Avaliação Tática no Futebol (FUT-SAT) e o Sistema de Análise Notacional em Jogos Reduzidos de Futebol para análise tático-técnica. Constatou-se que o princípio tático "cobertura ofensiva" foi executado com mais frequência pelos escolares praticantes de futsal (p = 0,01) seguido pelo princípio "espaço sem bola" (p < 0,01). Correlações significativas moderadas e fortes foram identificadas entre a frequência de execução dos princípios táticos fundamentais "penetração", "cobertura ofensiva", "espaço com bola", "unidade ofensiva" e a eficiência em habilidades técnicas (de r = 0,43 a r = 0,82, p < 0,05). Conclui-se que no grupo etário avaliado, existe um modelo de jogar próximo ao centro de jogo e que a eficiência de execução técnica está associada com o comportamento tático em situação de jogo.
