Abstract

This study has pursued to find the efficacy values in the playing microsituations present in water polo and to analyse the relation between these and the condition of winner or loser. Were recorded all female games of the X World Championship, for its consensus analysis between two trained specialists. Have been evaluated by means of coefficients the playing microsituations in numerical equality, counterattack, defensive adjustment, simple temporary numerical inequality and penalty; obtaining efficacy values. For the statistical analysis an ANOVA of a single factor was carried out by the Tukey test, revealing significant differences in numerical
equality with and without possession: in possibility (.005), concretion, definition and precision (.000), resolution (.001) and accuracy (.017). In the counterattack and defensive adjustment: in possibility, concretion, definition, resolution and precision (.000) and accuracy (.001). In simple temporary numerical inequality with and without possession: in possibility (.020), concretion, definition, precision and accuracy (.000) and resolution with possession (.002) and without possession (.003); taking as reference a value of p ≤ .05. There are significant differences between the condition of winner or loser in twelve coefficients of efficacy in numerical equality, twelve in transition, twelve in simple temporary numerical inequality and none in the penalty.
