- PublicationOpen AccessShort-term effects of adding 1-m wide to each side of the basketball court on youth players’ performance(Murcia: Servicio de publicaciones de la Universidad de Murcia, 2020) Mateus, Nuno; Gonçalves, Bruno; Exel, Juliana; Esteves, Pedro; Sampaio, JaimeThis study aimed to identify short-term effects on basketball players’ physical responses, technical performance, and tactical behaviour when the court dimension is increased 1-m wide to each side. Fourteen youth players participated in 5 vs. 5 simulated basketball games, under two different conditions: regular court (28x15m) and wider court (28x17m, 1-m wider for each side). Besides the assessment of physical and technical indicators, positional data were also used to compute the following variables: distance to the nearest opponent, distance to the nearest teammate, stretch-index and distance between centroids. Results indicated that in the wider court condition, the dispersion of player’s displacement trajectories duringthe offensive phase increased, which had slight repercussions on their physical responses and in the teams’ playing patterns. Conversely, during the defensive phase, players tended to move within the regular spatial references, regardless of court width manipulation. Overall, this study emphasizes that short-term effects of changing the court dimensions are relatively negligible, suggesting that informational constraints might require longer time-scales to yield robust changes in players’ performance.
- PublicationOpen AccessAnálisis de la técnica de tiro libre de jugadores de baloncesto en contexto formativo(Murcia: Servicio de publicaciones de la Universidad de Murcia, 2020) Díaz Aroca, Álvaro; Arias-Estero, José L.El objetivo fue determinar si la técnica de tiro libre ejecutada por jugadores de baloncesto de entre 9 y 11 años no participantes en ninguna selección autonómica y nacional coincidió con la técnica reportada por la literatura y estudios previos. El trabajo se realizó diferenciando la técnica de tiro antes de la salida y a la salida del balón. Participaron 12 jugadores varones de entre 9 y 11 años (M= 10,43, DT= ,63) que nunca habían participado en ninguna selección autonómica ni nacional. Se utilizó la metodología observacional a través de un diseño puntual/nomotético/multidimensional. Se grabó a los jugadores realizando un test que constaba de 10 tiros libres. Posteriormente, dos observadores observaron la ejecución técnica de cada uno de los tiros realizados por los jugadores. Se realizó la detección de t-patterns mediante el software Theme v.6 EDU. No se detectó ningún t-pattern antes de la salida del balón ni a la salida debido a que los tiros se realizaron siguiendo conductas muy dispares, que no se repitieron de forma regular en el tiempo. En el presente trabajo se utilizó un instrumento de observación que permitió la obtención de información directamente aplicable a la realidad diferenciando lo que ocurre antes de la salida del balón y a la salida del mismo. Se comprobó que los jugadores analizados, los cuales no jugaban en ninguna selección, ejecutaron una técnica de tiro que contrastaba en varios criterios conlas recomendaciones propuestas por la literatura y estudios previos.

- PublicationOpen AccessCorrelation between levels of physical activity and anxiety and in patients with binge-eating disorder(Murcia: Servicio de publicaciones de la Universidad de Murcia, 2020) Freire, Andrea da Silva; dos Santos, David; Vaz, Ana; Lima, João Lucas; Murillo-Rodriguez, Eric; Axt, Glaciane; Monteiro, Diogo; Cid, Luis; Machado, Sergio; Telles-Correia, DiogoBinge-eating disorder (BED) is linked to several psychiatric disorders, such as anxiety disorders. Approximately 50-60% of BED patients are resistant to the traditional treatments available, and thus, strategies supporting the treatment of BED are needed, such as physical activity (PA). It seems to be an interesting strategy to reduce BED and anxiety symptoms.Thus, since PA has a role in reducing BED episodes and improving anxiety symptoms, then more research is needed to clarify the role of PA on BED, as correlations between anxiety-BED and anxiety-PA are established. Therefore, our aim is to examine the relationship between PA and anxiety in patients with BED. Thirty two patients we submitted to psychological and PA questionnaires. A Pearson's correlationcoefficient and a multiple linear regression analysis were performed to relate eating disorder behaviour, anxiety and PA. The correlation coefficients between the dimensions of BED and anxiety were almost all significant (except restriction), positive andmoderate (p<0.001). Thus, the higher the eating disorder values, the higher the anxiety levels (p<0.01). In conclusion, our findings support that PA correlates with anxiety in patients with BED, suggesting that PA may decrease symptoms, such as the appetite, weight and body shape concerns.
