With this study has intended to obtain two objectives: the first one, to investigate the efficacy values in the playing microsituations in simple temporary numerical inequality with or without ball possession, and the second, to analyze the relation between these and the condition of loser at the end of the match and in both sexes. For the empirical part were recorded in video all the matches of the X Water polo World Championship celebrated in Barcelona during the month of July of 2003, for its subsequent analysis arrived at by consensus between two specialists previously coached, continuing the guidelines of the observational methodology. Valued themselves, by means of some coefficients, the efficacy in all the playing microsituations in simple temporary numerical inequality with or without ball possession obtaining some efficacy values. In the condition of loser at the end of the match differences were revealed among both sexes in the coefficient of shots exactness without possession (.008); taking as reference a value of p <.05. To conclude, to affirm that in one of the fourteen coefficients of efficacy proposed for evaluate the playing microsituations in simple temporary numerical inequality with or without ball possession in water polo are significant differences among sexes in teams with the condition of loser at the end of the match.<br /> <strong>Key words</strong><strong>:</strong> water polo, efficacy, loser, simple temporary numerical inequality.<br><p class="resumenyabstract" align="justify">Con este estudio se ha pretendido conseguir dos objetivos: el primero, indagar en los valores de eficacia en las microsituaciones de juego en desigualdad num&eacute;rica temporal simple con o sin posesi&oacute;n del bal&oacute;n, y el segundo, analizar la relaci&oacute;n entre los valores de eficacia en equipos con la condici&oacute;n de perdedor al finalizar el partido y en ambos sexos. Para la parte emp&iacute;rica se filmaron en v&iacute;deo todos los partidos de waterpolo del X Campeonato del Mundo celebrado en Barcelona durante el mes de Julio de 2003, para su posterior an&aacute;lisis consensuado entre dos especialistas previamente entrenados, siguiendo las directrices de la metodolog&iacute;a observacional. Se valor&oacute;, mediante unos coeficientes, la eficacia en todas las microsituaciones de juego en desigualdad num&eacute;rica temporal simple con o sin posesi&oacute;n del bal&oacute;n, obteniendo unos valores de eficacia. En la condici&oacute;n de perdedor al final del partido se revelaron diferencias entre ambos sexos en el coeficiente de exactitud de lanzamientos sin posesi&oacute;n (.008); tomando como referencia un valor de p<.05. Para concluir, afirmar que s&oacute;lo en uno de los catorce coeficientes de eficacia propuestos para evaluar las microsituaciones de juego en desigualdad num&eacute;rica temporal simple con o sin posesi&oacute;n del bal&oacute;n en waterpolo existen diferencias significativas entre sexos en equipos con la condici&oacute;n de perdedor al finalizar el partido. <br /> <strong> Palabras clave: </strong>waterpolo, eficacia, perdedor, desigualdad num&eacute;rica temporal simple.</p>
