Este trabajo ha sido parcialmente subvencionado por la Ayuda a los Grupos de Investigación (GR18170) del Gobierno de Extremadura (Consejería de Empleo, Empresa e Innovación); con la aportación de la Unión Europea a través de los Fondos Europeos de Desarrollo Regional.Resumen: Introducción: En baloncesto, la cuantificación de la carga en competición es una herramienta muy utilizada por entrenadores con el fin de definir objetivos y controlar la evolución de los jugadores. Aun así, los jugadores no participan del mismo modo durante la competición, existiendo jugadores con un estímulo de minutos superior al de otros. Objetivos: Conocer como varía la demanda física de la competición en función del tiempo de participación en el juego de cada deportista. Métodos: Se analizaron 12 partidos de competición de baloncesto femenino de formación U18, dónde se registró la carga cinemática a través de la distancia recorrida, número de sprines, aceleraciones y deceleraciones, impactos, saltos y PlayerLoad. Todas estas variables se analizaron en función de la carga de minutos (1-10’, 10-20’, 20-30’ y de 30-40’). Los datos fueron recogidos a partir de tecnología de banda ultra ancha (UWB) y dispositivos inerciales (WIMUTM). Resultados y discusión: Se observa una línea ascendente en todas las variables analizadas al incrementar el tiempo de juego. Sin embargo, analizando las variables ponderadas al minuto (número de acciones por minuto) se identifica una disminución del rendimiento final cuando las jugadoras se mantienen en pista más de 30 minutos. Conclusiones: Se ha diferenciado la carga competitiva en función de los minutos de juego, permitiendo reestructurar el tiempo entre las jugadoras de un equipo con el objetivo conseguir un rendimiento físico óptimo durante todo el partidoAbstract: Introduction: In basketball, the quantification of the load in competition is a tool widely used by coaches in order to define objectives and control the evolution of the players. Even so, players do not participate in the same way during the competition, there being players with a stimulus of minutes superior to others. Aim: To know how the physical demand of the competition varies depending on the time of participation in each athlete's game. Methods: 12 games of women's U18 basketball competition were analyzed, where the kinematic load was recorded through distance perform, number of sprints, accelerations and decelerations, impacts, jumps and PlayerLoad. All these variables were analyzed according to the load of minutes (1-10 ', 10-20', 20-30 'and 30-40'). The data was collected from Ultra Wide Band (UWB) and inertial devices (WIMUTM). Results & discussion: An ascending line is observed in all the analyzed variables when increasing the playing time. However, analyzing the weighted variables at minute (number of actions per minute) a decrease in the final performance is identified when the players stay on the track for more than 30 minutes. Conclusions: The competitive load has been differentiated according to the minutes of the game, allowing to restructure the time between the players of a team with the aim of achieving optimal physical performance throughout the game.Resumo: Introdução: No basquete, a quantificação da carga na competição é uma ferramenta amplamente utilizada pelos treinadores para definir objetivos e controlar a evolução dos jogadores.

Multi-Location External Workload Profile in Women’s Basketball Players. A Case Study at the Semiprofessional-Level

The external workload measured in one anatomical location does not determine the total load supported by the human body. Therefore, the purpose of the present study was to characterize the multi-location external workload through PlayerLoadRT of 13 semi-professional women’s basketball players, as well as to analyze differences among anatomical locations (inter-scapulae line, lumbar region, 2× knee, 2× ankle) and laterality (left vs. right) during five tests that represent the most common movements in basketball—(a) linear locomotion, 30-15 IFT; (b) acceleration and deceleration, 16.25-m RSA (c) curvilinear locomotion, 6.75-m arc (d) jump, Abalakov test (e) small-sided game, 10’ 3 vs. 3 10 × 15-m. Statistical analysis was composed of a repeated-measures t-test and eta partial squared effect size. Regarding laterality, differences were found only in curvilinear locomotion, with a higher workload in the outer leg (p &lt; 0.01; ηp2 = 0.33–0.63). In the vertical profile, differences among anatomical locations were found in all tests (p &lt; 0.01; ηp2 = 0.56–0.98). The nearer location to ground contact showed higher values except between the scapulae and lumbar region during jumps (p = 0.83; ηp2 = 0.00). In conclusion, the multi-location assessment of external workload through a previously validated test battery will make it possible to understand the individual effect of external workload in each anatomical location that depends on the type of locomotion. These results should be considered when designing specific strategies for training and injury prevention

Exploring Physical Fitness Profile of Male and Female Semiprofessional Basketball Players through Principal Component Analysis—A Case Study

Basketball is a sport in continuous evolution, being one of these key aspects of the players’ physical fitness that has an impact on the game. Therefore, this study aimed to characterize and identify the physical fitness level and profiles of basketball players according to sex. Total of 26 semi-professional basketball players were assessed (13 male, 13 female) through inertial devices in different previously validated fitness tests. T-test for independent samples and principal component analysis were used to analyze sex-related differences and to identify physical fitness profiles. The results showed differences according to sex in all physical fitness indexes (p &lt; 0.01; d &gt; 1.04) with higher values in males, except in accelerometer load during small-sided games (p = 0.17; d &lt; 0.20). Four principal components were identified in male and female basketball players, being two common ([PC1] aerobic capacity and in-game physical conditioning, [PC4 male, PC3 female] unipodal jump performance) and two different profiles (male: [PC2] bipodal jump capacity and acceleration, [PC3] curvilinear displacement; female: [PC2] bipodal jump capacity and curvilinear displacement, [PC4] deceleration). In conclusion, training design must be different and individualized according to different variables, including physical fitness profiles between them. For practical applications, these results will allow knowing the advantages and weaknesses of each athlete to adapt training tasks and game systems based on the skills and capabilities of the players in basketball
