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.

El objetivo del presente trabajo ha sido conocer el punto de vista que tiene el jugador sobre el concepto de momento crítico en baloncesto. Para ello, se ha realizado una investigación cualitativa, utilizando como técnica de investigación la entrevista semi-estructurada. Se entrevistaron a 8 jugadores de la liga A.C.B (Asociación de Clubes de Baloncesto) durante la temporada 2015/16, con más de 10 años de experiencia en liga y en sus respectivas selecciones nacionales. Los resultados indican que la muestra reconoce el factor de incertidumbre asociado al concepto de momento crítico, identifican los últimos minutos de partidos equilibrados como momento crítico del juego. Los jugadores señalan que la confianza es vital para afrontar el fenómeno y que la experiencia puede eliminar las tensiones que se puedan generar (AU)

They were interviewed 8 players of the league A.C.B (Association of Clubs of Basketball) during the season 2015/16, with more than 10 years of experience in league and in his respective national teams. The results indicate that the sample recognizes the factor of uncertainty associated with the concept of critical moment, identify last minutes of games balanced as critical moment of the game. The players indicate that the confidence is vital to confront the phenomenon and that the experience may eliminate the tensions that could be generated (AU)
