ABSTRACT
Given the intermittent nature of basketball and the different demands that occur during playing time that are specific to every level of competition, the ratio of accelerations/decelerations and the intensity level across quarters were evaluated in female elite junior basketball players (n = 48; age: 16.8 ± 0.7 years; height: 1.76 ± 0.07 cm; body mass: 67.2 ± 6.2 kg). The following variables were analyzed to determine physical persistency across game quarters:(a) total distance covered (m), (b) high-intensity running (HIR) (14-21 km·h-1) distance covered (m), (c) sprint (21-30 km·h-1) distance covered (m), (d) total accelerations (n), (e) total decelerations (n), (f) relative accelerations (n·min-1), (g) relative decelerations (n·min-1), (h) ratio of acceleration/deceleration (A/D), (i) total jumps (j) relative jumps (n·min-1) (k) player load (AU). using the WIMU PRO® system. Higher but shorter acceleration intensity occurred during the last quarters due to the tight results of the matches. The results suggest that high-intensity efforts such as sprints and HIR seem to increase the A/D ratio (guard and forward positions). Therefore, specific conditioning, as well as eccentric strength training, could be included by practitioners in training programs to improve the performance of these positions during competition, especially as a prior preparation to a game-congested event. Centers seem to have a more variable performance through quarters than do other positions, perhaps highlighting the need for specific conditioning strategies.

Relative age effects (RAEs) appear consistently prevalent throughout the youth basketball literature. However, the selection into and successful transition out of a national talent pathway in basketball is yet to be explored. Thus, the primary aim of this study was to explore the influence of relative age, gender, and playing time based on the selection into the Regional Talent Hubs and Basketball England youth teams (U16, U18, and U20) and the successful transition into the England National Senior Teams. Participants who were selected into the male (n = 450) and female (n = 314) Basketball England Talent Pathway were allocated into one of three cohorts: (a) Regional Talent Hubs (U12 to U15; n = 183), (b) England National Youth Teams (U16, U18, and U20; n = 537), and (c) England National Senior Teams (n = 44). A chi-square test was used to compare the birth quarter (BQ) distributions of each cohort against the expected distributions, with a Cramer's V (Vc) used to interpret effect sizes. Odds ratios (OR) and 95% confidence intervals were also calculated to compare the likelihood of each BQ being represented. Males revealed significant RAEs across both the Regional Talent Hubs (p < 0.001, Vc > 0.29, OR = 10) and England National Youth Teams (p < 0.001, Vc > 0.17, OR = 3.1). In comparison, females only had significant RAEs in the Regional Talent Hubs (p < 0.001, Vc > 0.29, OR = 2.3). Despite RAEs being prevalent throughout youth levels, there were no significant differences in the BQ distribution based on playing time and those who made the successful transition to the England National Senior Teams. These findings demonstrate the potential mechanisms of RAEs in basketball, as well as the impetus to explore more equitable competition structures within the England Basketball Talent Pathway.
ABSTRACT
El presente trabajo busca analizar el rol del entrenador como mentor de deportistas en etapas de formación en baloncesto. Para ello se ha realizado un estudio cualitativo de 12 díadas entrenador deportista (N=24) seleccionadas deliberadamente, discriminando variables establecidas por la literatura específica como criterios determinantes para la mejora de la relación (nivel deportivo del equipo, características del entrenador, duración de la relación y calidad de la misma). Los resultados muestran cómo diferentes componentes de la relación inciden en el crecimiento personal por parte de los jugadores, fruto de una relación cercana y basada en el apoyo y cuidado de aspectos de carácter extradeportivo (AU)
The aim of this paper is to analyse the role of the coach as mentor of basketball youth players. A qualitative study was conducted. The sample (12 dyads coach-athlete, N=24) was deliberately selected, discriminating variables set by the specific literature as determining criteria for improving the relationship (sports team level, characteristics of the coach, duration of the relationship, and quality of the relationship). Results revealed the influence of the different components of the relationship in players personal growth, as a result of a close relationship based on support and personal care (AU)

El rendimiento en los tiros libres bajo condiciones de presión puede estar relacionada con múltiples variables. En este sentido, el objetivo principal de este trabajo será conocer si existe una disminución de rendimiento durante el último minuto de los partidos ajustados, y con cuáles de esas variables está más relacionada. Para alcanzar este objetivo, se analizaron 124 partidos ajustados (diferencias iguales o inferiores a dos puntos) de todas las competiciones (fase regular, playoff y copa del Rey) de la liga ACB durante las temporadas 2011-2012 a 2014-2015, registrando el porcentaje de acierto en los tiros libres del lanzador en la liga regular, partido completo, y último minuto del mismo. Los resultados principales del estudio mostraron que existe una disminución del rendimiento en el porcentaje de acierto en los tiros libres durante el último minuto del partido, y que está relacionada significativamente con la edad, experiencia profesional, puesto de juego del jugador, y diferencia parcial en el marcador (AU)
Performance on free throws under pressure conditions may be related to multiple variables. In this sense, the main aim of this work will be to know if there is a decrease in performance during the last minute of tight games, and which of those variables is more related with it. To achieve this aim, 124 tight games (less or equal than two points differences) of every competition (regular season, playoff, and cup) of the ACB league during 2011-2012 to 2014-2015 seasons were analyzed to record the percentage in free throws of the player in the regular season, complete game, and last minute of the game. The main results of the study showed there is a decrease in performance about the percentage in free throws in the last minute of the game, and it is significantly associated with age, professional experience, player position, and scoreline (AU)
