“…Around 23.7% of shots in women's games in the world championship happened in an H+ situation. This frequency was only lower than that found for attacks in situations of numerical equality (57.5%) 12 . Thus, the situations with positional attacks in numerical equality that lead to the exclusion of defenders must be a part of the players' training routines.…”

“…A similar result is found in various other studies involving players of both sexes and at different performance levels 3,4,10,11 . However, a study with women's teams in the world championship demonstrated that H+ was different for medallist and non-medallist teams in the competition's preliminary phase 12 .…”

“…In women's team with a similar performance level, more goals are scored in counterattacks and in attacks with numerical equality than in H+ 12 . On the other hand, with men's teams, also in the world championship, the teams that won and lost the matches classified as balanced (≤ 3 goals) had more H+ opportunities than the teams that won and lost with unbalanced scores (> 3 goals).…”

This study compared the frequency, number of goals and attack efficiency in temporal numerical superiority among winning and losing teams and among balanced and unbalanced matches in a junior men’s water polo competition. Another analysed relationship was that between a balanced or unbalanced final score and the efficiency at scoring goals in numerical superiority in the winning teams’ games. A total of 56 matches from the Pan-American Junior Men’s Water Polo championship was analysed. The teams were categorised as losers or winners and the match results were classified as balanced or unbalanced. The chi-squared and Mann-Whitney tests were used for statistical treatment. There is no significant difference in the occurrence of numerical superiority between winners and losers (p = 0.25) despite the winners scoring more goals (p = 0.002) and being more efficient (p < 0.001). There is no significant difference in the occurrence of numerical superiority (p = 0.81) and goals (p = 0.03) in balanced and unbalanced matches. However, there tends to be a higher shot efficiency (p = 0.01) in unbalanced matches. A significant relationship exists (p = 0.04) between the winning teams’ efficiency at scoring goals in a situation of numerical superiority and an unbalanced score.

“…The efficiency of man-up in water polo is an important factor that influences the result of games (Takagi, Nishijima, Enomoto, & Stewart, 2005;Platanou, 2004). Some studies have reported a significant difference of man-up efficiency between different levels of competition in water polo teams (Garcia-Marin, Iturriaga, & Manuel, 2017;Tucher, Canossa, Cabral, Garrido, & De Souza Castro, 2015;Lupo, Condello, Capranica, & Tessitore, 2014).

In water polo, time-outs last one minute and only a team in possession of the ball can request one; although there are diverse opinions whether a time-out is advantageous for the team in possession. The aims of this study were, firstly, to identify and to explain the impact of time-out on the efficiency of man-up in water polo, and secondly, to identify and to explain the differences in the efficiency of man-up in water polo between three qualitative levels of players. The sample consisted of 132 matches of the Adriatic Water Polo League, who were observed for indicators of man-up efficiency. There was no statistically significant difference between man-up efficiency played after a time-out and man-up efficiency played without a time-out. Additionally, the Kruskal-Wallis test partially confirmed the existence of significant differences between three qualitative levels of water polo players. There is a reasonable possibility that the differences between levels are generated by the differences in tactical knowledge, motor ability, and scoring ability. Trainers can apply the results of this study for the selection of appropriate tactical solutions and the optimization of training processes among elite and sub-elite water polo players. Additionally, the study's results can be the basis for further research dealing with exploring the dynamics of water polo, observed through recent changes in the rules.

“…Players and researches have used these performance indicators to improve the understanding of game performance in different types of competitions. Thus, a large number of research works have studied performance indicators in short term competitions such as Olympic Games, World Championships, or European Championships (Escalante, Saavedra, Mansilla & Tella, 2011;Escalante, Saavedra, Tella, Mansilla, García & Domínguez, 2012;Escalante, Saavedra, Tella, Mansilla, García & Domínguez, 2013;García-Marín & Argudo, 2017;Lupo, Condello, Capranica & Tessitore, 2014;Lupo, Condello & Tessitore, 2012a;Martínez & González, 2020;Sabio, Argudo, Guerra & Cabedo, 2021;Sabio, Guerra & Cabedo, 2018). For example, some research identified offensive characteristics (centre goals, power-play goals, counterattack goal, assists, offensive fouls, steals, blocked shots, and won sprints) and defensive characteristics (goalkeeper-blocked shots, goalkeeper blocked inferiority shots, and goalkeeper-blocked 5m shots) which distinguished performance for each phase in international championships (Escalante et al 2013).…”

The purpose of the present study was to identify the indicators of offensive effectiveness which best discriminate by match score (favourable, balanced or unfavourable) in water polo. The sample comprised 88 regular season games (2011-2014) from the Spanish Professional Water Polo League. Univariate (ANOVA test; Kruskal-Wallis test and Generalized Linear Model test (GLM)) and multivariate (Discriminant) analysis were used to compare favourable, balanced or unfavourable games, and effect sizes of the differences for the indicators were calculated. The results showed that favourable games had averages that were significantly higher for the success rate in even attacks and shots, power-play attacks and shots, counterattack and counterattack shots, shots from zone 1, 2, 3, 4, 5 and 6, drive shots, and shots after 1, 2 and more than 2 fakes. The indicators of offensive effectiveness that most discriminated were the success rate for drive shots (SC=-.624), even attacks and shots (SC=-.359 and SC=-.322, respectively), and for power-play actions and shots (SC=-.343 and SC=-.321, respectively). These results could help coaches when planning training and competition, providing them with the percentages of offensive effectiveness that must be reinforced in order to have more chances to win the match. This information can help coaches to evaluate their teams and to design training aimed at improving their weakest skills. Resumen: El objetivo del presente estudio fue identificar los indicadores de eficacia ofensiva que mejor discriminan en función del resultado del partido (favorable, equilibrado o desfavorable) en el waterpolo. La muestra estuvo formada por 88 partidos de temporada regular (2011-2014) de la Liga Española de Waterpolo Profesional. Se utilizaron análisis univariados (prueba ANOVA; prueba de Kruskal Wallis y prueba del Modelo Lineal Generalizado (GLM)) y multivariante (discriminante) para comparar resultados favorables, equilibrados o desfavorables, y se calcularon los tamaños del efecto de las diferencias para los indicadores. Los resultados mostraron que los equipos con resultado favorables tenían promedios significativamente más altos para la tasa de efectividad en ataques y lanzamientos en igualdad, ataques y lanzamientos en superioridad, ataques y lanzamientos de contraataque, lanzamientos de zona 1, 2, 3, 4, 5 y 6, lanzamientos directos y después de 1, 2 y más de 2 efectividad en lanzamientos directos (SC=-.624), ataques y lanzamientos en igualdad (SC=-.359 y SC=-.322, respectivamente), y ataques y lanzamientos en superioridad (SC=-.343 y SC=-.321, respectivamente). Estos resultados podrían ayudar a los entrenadores a la hora de planificar los entrenamientos y la competición, proporcionándoles los porcentajes de efectividad ofensiva que se deben reforzar para tener más posibilidades de ganar el partido. Puede ayudar a los entrenadores a evaluar a sus equipos y diseñar entrenamientos destinados a mejorar sus habilidades más débiles.
