Athletes were monthly evaluated by means of the field test using the System of Tactical Assessment in Soccer – FUTSAT, which allowed the characterization of the incidence of tactical principles and place of action in the game field, as well as the percentage of positive offensive and defensive tactical principles. Data were analyzed by Friedman’s test (incidence of tactical principles and place of the action) and one-way ANOVA for repeated measures (percentage of positive tactical principles), adopting significance level of p<0.05. Results showed differences in the incidence of offensive and defensive units tactical principle, as well as the place of actions in the game field.
