Water polo shot indicators according to the phase of the championship: medallist versus non-medallist players

Abstract The objective of this study was to compare the technical and tactical water polo shot indicators between medallist and non-medallist teams in the preliminary and final phases of the XV FINA Women’s World Championship and to compare shot indicators between both phases of the championship for each classification category. A nomothetic observational, multidimensional and longitudinal design was used. A total of 2463 throws recorded in 44 matches were studied using match analysis. A descriptive and covariance analysis was performed with the univariate general linear model. The difference in the number of goals in the final score was introduced as a covariate. In both phases of the championship, significant differences (p ≤ .05) were found between medallist and non-medallist players in equality and counterattack. Significant differences were also found in power play, but only in the preliminary phase. Penalty shot indicators were similar for all teams in both phases of the championship. The dynamics of the medallist players’ throws varied in more indicators and situational frameworks from the preliminary phase to the final phase when compared with the non-medallist players. Match analysis allowed the discrimination of performance factors in medallist and non-medallist players and suggested practical applications for throw training.

Water polo: technical and tactical shot indicators between winners and losers according to the final score of the game

Abstract The objective of this study was to compare the technical and tactical shot indicators in water polo between the winners and losers in balanced (≤3 goals difference) and unbalanced (>3 goals) matches in each situational framework (even action, counter-attack, power play and penalty). A total of 2378 shots from the 44 women’s matches in the XV World Championship were analysed. A descriptive analysis and a variance analysis were performed for comparison of means (p ≤ .05). No significant differences were found in the balanced matches. In unbalanced matches, differences arose in even action (zone of origin of prior pass, reception, position, free shot, result and goal zone), counter-attack (position and goalie position in width) and power play (technical gesture, result, goal zone, defender orientation, contact and proximity between defender and attacker). No differences were found in the indicators analysed for penalty. The notational analysis allows for the discrimination of performance factors according to the winner–loser condition and suggests practical applications for training in shooting.

Efectes de tenir la primera possessió de la pilota sobre els marcadors parcial i final en els Campionats del Món de Waterpolo de 2005 i 2007

L’objectiu d’aquest estudi va ser analitzar la influencia de tenir la primera possessio de la pilota sobre els marcadors parcial i final en waterpolo masculi i femeni. Els participants van ser 416 homes de 32 equips masculins i el mateix nombre de dones del mateix nombre d’equips, que van prendre part en els Campionats del Mon de 2005 i 2007. La mostra va estar formada per les accions d’inici de cadascun dels quatre periodes dels 192 partits enregistrats, la qual cosa va suposar un total de 768. Es va utilitzar la metodologia observacional, mitjancant un disseny de tipus nomotetic, seguiment i multidimensional. El 45,7 % dels equips masculins i el 51,8 % dels equips femenins que van aconseguir la primera possessio de la pilota van gaudir d’un resultat parcial favorable al llarg dels periodes. Els equips femenins que van guanyar mes del 50 % dels partits van agafar la primera pilota en mes de dos periodes. Aconseguir la primera pilota en un nombre mes gran de periodes es relaciona amb un marcador parcial favorable en ambdues categories i amb un marcador final favorable en la categoria femenina.

CARACTERÍSTICAS ANTROPOMÉTRICAS, COMPOSICIÓN CORPORAL Y SOMATOTIPO EN JUGADORES DE ÉLITE DE WATERPOLO

Este estudo descreve a estrutura antropometrica dos melhores jogadores de polo aquatico espanhois nas categorias junior e senior; em segundo lugar, pretende determinar se existem diferencas antropometricas, na composicao corporal e no somatotipo entre ambas as categorias. A amostra utilizada no estudo foram 23 jogadores da seleccao espanhola de polo aquatico, de entre os quais 9 jogadores de categoria junior e 14 seniores. As diferencas mais evidentes entre ambas as categorias foram encontradas nas variaveis que tem uma relacao indirecta com os niveis de forca, e com a experiencia. Os jogadores da categoria junior apresentam um somatotipo mesomorfico equilibrado, enquanto os jogadores da categoria senior apresentaram um somatotipo endo-mesomorfico.
