The aim of this study was twofold: to know if the left-handed players are more effective in the goal categories and getting positive actions, in 1 and 2 position, than the right-handed in the same position at numerical inequality. To ascertain if the shots in 1 and 2 position, are less effective than the rest of the positions in the goal categories. A nomothetic observational, multidimensional and punctual design was used. The sample was the 389 shots and the 182 positive actions of 24 games (12 male and 12 female) at 15th FINA World Championship held in Barcelona. To record the data was used an ad hoc instrument for observation through the Sport Code Version Pro V9. Descriptive and Chi-square test was applied to study the relationship between variables. Left-handed players are more effective than right-handed players are if they are related to the goal and positive action categories in position 1. Shots from position 1 are the second least effective while position 2 is the fifth most effective.
Resumen. El objetivo de este estudio fue doble: saber si los jugadores zurdos son más efectivos en las categorías de gol y obtener acciones positivas, en la posición 1 y 2, que los diestros en la misma posición en la desigualdad numérica. Determinar si los lanzamientos desde posición 1 y 2 son menos efectivos que desde el resto de posiciones en las categorías de gol. Se utilizó un diseño nomotético observacional, multidimensional y puntual. La muestra fueron los 389 tiros y las 182 acciones positivas de 24 juegos (12 masculinos y 12 femeninos) en el 15º Campeonato Mundial FINA celebrado en Barcelona. Para registrar los datos se utilizó un instrumento ad hoc para observación a través del software Sport Code Version Pro V9. Se aplicó la prueba descriptiva y de Chi-cuadrado para estudiar la relación entre las variables. Los jugadores zurdos son más efectivos que los diestros si están relacionados con el objetivo y las categorías de acción positiva en la posición 1. Los lanzamientos desde la posición 1 son los segundos menos efectivos, mientras que desde la posición 2 es la quinta más efectiva.
