The purpose of this research was to investigate the structure of the ball behavior in the futsal teams during the offensive  phase. The type of research was observational and the data extracted from the 12 games in the training matches of the players of the futsal resistance team present at the Premier League matches of 97-98 were recorded and analyzed. Using the SOCNET software, the values of the cluster coefficient were calculated and using the MATLAB software, Shannon entropy values for each team were calculated. The results showed that by increasing the number of training sessions, the values of the cluster and entropy coefficient of Shannon increased in both teams and there is a moderate correlation between the values of the cluster coefficient and Shannon entropy was observed with the number of training sessions. In general, and according to the results of this study, the functional variability of ball behavior patterns increased with training and team experience, and the level of complexity and unpredictability of the team network increased. According to the sensitivity of the behavioral patterns of the ball to the effects of training, sport analyzers can use the information from this level of analysis to explain the team's synergistic behaviors in futsal teams.
