ABSTRACT

The aim of this study was to investigate the role of age and intellectual impairment (II) in decision-making in basketball. The current study investigated differences in decision making between equally well-trained adult basketball male players with intellectual impairment (players with II) (n = 93), adults without II (senior) (n = 44) and youth basketball players (under-14, n = 31; under-16, n = 25; under-18, n = 30). A computer test was developed composed by 20 photographs displaying various basketball game-situations, and participants had to decide as fast as possible what the player in ball possession should do: dribble, pass or shoot. Decision time and accuracy were recorded for every situation. Players with II had slower decision time (3.8 ± 1.8 s vs. 1.5 ± 0.5 s, p < 0.001) and less decision-making accuracy (15.7 ± 2.8 correct decisions vs. 17.9 ± 1.2 correct decisions, p < 0.001) compared to senior players without II. Discriminant analysis with speed and accuracy as independent variables classified 91.2% (CCA = 0.769) of the players correctly into their group: players with II or players without II. A Spearman correlation revealed that age correlated significantly (p < 0.001) with the number of correct decisions (rs = 0.269) and mean decision time (rs = -0.331). Our findings support that decision making in basketball develops with age and experience, but is significantly deteriorated in experienced adult players who have II. Decision-making should be considered as an important eligibility criterion to participate in competitive basketball events for male players with II.

ABSTRACT

The development of evidence-based eligibility systems in basketball for athletes with intellectual impairment (II) requires investigating the influence of II on performance. Due to this, the present study aimed to compare game-related statistics from II and able-bodied (AB) competitions. The World Men II-Basketball Championship 2013 (n=13 games and 63 players) and the Spanish Men AB-Basketball Championships 2014 under 16- years-old (n=10 games and 95 players) and under 18-years-old (n=18 games and 175 players) were analyzed. Team and individual statistics were normalized to 100 ball possessions and to 40 minutes played respectively. One-way ANOVA and post hoc Tukey tests were conducted to compare II and AB-teams. Also, a discriminant analysis was employed to identify which variables discriminated them best. The Kruskal-Wallis and U Mann-Whitney tests were applied to compare the II and AB individual game-related statistics. II-teams played more ball possessions per game (p<0.05) and the variables which best discriminated II and AB-teams were: 2-point unsuccessful shots │SC=-0.384│, 3-point successful │SC=0.456│, 3-point unsuccessful │SC=-0.399│, free-throws successful │SC=0.319│ and fouls │SC=0.454│. In all playing positions II-players presented more 2-point unsuccessful and lower shooting percentage in all kind of shots. II-guards attempted more field shots and made more turnovers than their peers, showing an unbalanced roles´distribution compared with AB-players. These results confirmed that II and AB-players perform basketball in different ways (AU)


El desarrollo de sistemas de elegibilidad basados en la evidencia en baloncesto para deportistas con discapacidad intelectual (DI) requiere investigar la influencia de la DI en el rendimiento. Debido a ello, el presente estudio tuvo por objetivo comparar las estadísticas de juego en competiciones para personas con DI y sin discapacidad (SD). El Campeonato del Mundo de Baloncesto-DI de 2013 (n=13 partidos y 63 jugadores) y los Campeonatos de España de Baloncesto-SD de 2014 sub-16 (n=10 partidos y 95 jugadores) y sub-18 (n=18 partidos y 175 jugadores) fueron analizados. Las estadísticas de equipo e individuales fueron normalizadas a 100 posesiones de balón y 40 minutos de juego respectivamente. Los test one-way ANOVA y post hoc Tukey fueron utilizados para comparar los equipos con DI y SD. También se realizó un análisis discriminante para identificar qué variables los discriminaban mejor. Los test Kruskal-Wallis y U Mann-Whitney fueron empleados para comparar las estadísticas individuales de los jugadores con DI y SD. Los equipos con DI jugaron más posesiones de balón por partido (p <0.05) y las variables que más discriminaron los equipos con DI y SD fueron: lanzamientos de 2 puntos fallados │SC=-0.384│, 3 puntos encestados │SC=0.456│, 3 puntos fallados │SC=-0.399│, tiros libres encestados │SC=0.319│ y faltas │SC=0.454│. En todas las posiciones de juego los jugadores con DI presentaron más fallos de 2 puntos y menor porcentaje de tiro en todo tipo de lanzamientos. Los bases con DI intentaron más lanzamientos de campo y cometieron más pérdidas que sus compañeros, mostrando un desequilibrio entre la distribución de roles comparado con los jugadores SD. Estos resultados confirmaron que los jugadores con DI y SD rinden de manera diferente en baloncesto (AU)

ABSTRACT

Basketball for players with intellectual impairment (II) is not included as a Paralympic modality due to the lack of evidence based eligibility systems to ensure that only athletes with significant limitations performing basketball participate in II-competitions. Eligibility systems in II-basketball are under development but is necessary to investigate the impact of the impairment in basketball. The aim of this study was to know the point of view of II- coaches and referees about the limitations of their players and the components that should be considered as eligibility criteria. Qualitative method was used in our research. For that 5 open questions were elaborated based on the components of the game identified in the literature. 47 coaches and 6 referees were interviewed through an online survey. The findings of this study indicated that tactical aspects was the component in which II-players present more limitations and should discriminate between eligible and no eligible players followed by technical skills, emotional aspects and cognitive aspects. Physical and motor skills were not considered as limitation but specific positions and roles during the game could be influenced by these components. These results as well as other similar studies that show the opinion of coaches and referees should be taken into consideration to orientate future research to develop evidence-base eligibility systems in this sport (AU)


: El baloncesto para personas con discapacidad intelectual (DI) no está incluido como modalidad paralímpica debido a la falta de sistemas de elegibilidad basados en la evidencia que aseguren que, sólo deportistas con limitaciones significativas para practicar baloncesto participan en competiciones específicas. Los sistemas de elegibilidad en jugadores DI están en desarrollo pero es necesario investigar sobre el impacto de la discapacidad en el baloncesto. El objetivo del presente estudio fue conocer, desde el punto de vista de los entrenadores y árbitros, las limitaciones que sus jugadores DI presentan y aquellos componentes que deberían de ser considerados como criterios de elegibilidad. La metodología utilizada en nuestro estudio es cualitativa. Para ello, cinco preguntas abiertas fueron elaboradas basadas en los componentes del juego identificados en la literatura. 47 entrenadores y 6 árbitros fueron entrevistados a través de una encuesta on-line. Los resultados muestran que los aspectos tácticos fueron aquellos en los que los jugadores presentaban mayores limitaciones y permitían discriminar que un jugador fuese elegible o no; seguido de las habilidades técnicas, aspectos emocionales y aspectos cognitivos. Las habilidades físicas y motoras no se consideraron como una limitación pero podrían estar influenciados por las posiciones y roles específicos durante el juego. Estos resultados, así como otros estudios similares que muestren la opinión de los entrenadores y árbitros, deberían de ser tenidos en cuenta para orientar futuras investigaciones con el fin de desarrollar sistemas de elegibilidad basados en la evidencia de este deporte (AU)

ABSTRACT

El análisis del rendimiento deportivo del jugador de baloncesto en silla de ruedas (BSR) ha sido un creciente objeto estudio en los últimos años. Sin embargo, escasos estudios han incidido en las estadísticas de juego. Por ello, el presente estudio tiene por objeto determinar un referente de rendimiento máximo para cada clase funcional en base a cada variable de la estadística de juego propia de la competición. Para ello, se obtuvieron las estadísticas de juego oficiales de los 32 partidos disputados por los 8 mejores equipos de España en la fase por el título de la División de Honor de BSR (temporada 2013/2014), recabando información por jugador y partido; en total fueron estudiados 58 jugadores correspondientes a la clases 1 (n=11), 2 (n=12), 3 (n=12) y 4 (n=23). En relación a los porcentajes de tiro, el de 2p sitúa entre el 60,8-67,6% de acierto, realizando más lanzamientos a mayor clase funcional. Para los lanzamientos de 3p fue de 41,2-42,9% (sólo clases 2,3 y 4). Para los lanzamientos de 1p fue de 66,7%-89,5%) siendo el jugador clase 4 el porcentaje mayor y más número de lanzamientos realizados. Los datos máximos obtenidos se registraron en los jugadores de clase 4, con más rebotes ofensivos (4,12) y defensivos (9,99) registrados, así como faltas recibidas (9,95), asistencias (10,8), robos (1,99) y puntos anotados (29,4). Este estudio ha permitido la caracterización del rendimiento en este deporte, destacando la importancia contrastar el rendimiento de cada jugador con los de su misma clase funcional según la estadística de juego (AU)

The analysis of the sport performance in wheelchair basketball (WB) has been a growing topic in recent years. However, few studies have focused on the game statistics. Therefore, the present study is to determine a reference for maximum performance for each functional class based on each variable from game related statistics. To this end, official statistics from 32 matches for the top 8 teams in the title league at the Spanish Honour Division (season 2013/2014) were obtained with information per player and game; a total of 58 players corresponding to the classes 1 (n = 11), 2 (n = 12), 3 (n = 12) and 4 (n = 23) were studied. Regarding the shooting percentages, the 2-points was 60.8 to 67.6% accuracy, making more shots in higher functional classes. 3-points was 41.2 to 42.9% (only classes 2,3 and 4). 1-point free throw was 66.7% -89.5%, with class 4 player with the highest percentage and number of throws made. The maximum data obtained were recorded in class 4 players with more offensive rebounds (4.12) and defensive (9.99) registered and fouls received (9.95), assists (10.8), steals ( 1.99) and points scored (29.4). This study has allowed the characterization of performance in WB, stressing the importance in comparing the performance of each player with those of the same functional class per game statistics (AU)
