El objetivo de la investigación fue conocer los niveles de actividad física y satisfacción de las Necesidades Psicológicas Básicas en adolescentes de la Comarca de Extrema Siberia. Además de analizar las diferencias en la función sexual, así como analizar la relación entre los niveles de actividad física, la satisfacción de las necesidades psicológicas básicas y el sexo. La muestra estuvo realizada por 204 sujetos (92 hombres, 112 mujeres) con edades comprendidas entre 10 y 16 años. Para analizar el nivel de actividad física se utilizó el Cuestionario de Evaluación de Niveles de Actividad Física (APALQ) y la escala de Necesidades Psicológicas Básicas en Educación Física (BPN-PE), para evaluar las necesidades psicológicas básicas. Los resultados mostraron unos niveles de actividad física (nivel moderadamente activo, muy cercano al nivel sedentario) y necesidades psicológicas básicas que no eran muy elevadas. Respecto al sexo, se observó que las mujeres presentaron un nivel de actividad física sedentaria en comparación con el nivel moderadamente activo del sexo masculino. En concreto, se encontrarán diferencias significativas en los niveles de actividad física y competencia en relación al sexo. Por tanto, el sexo masculino se siente más competente y realiza mayores niveles de actividad física que el sexo femenino. Además, se observó cómo se relacionaban entre sí el sexo, la actividad física y la satisfacción de necesidades psicológicas básicas. Destacando la correlación positiva y significativa entre sexo y competencia, niveles de actividad física y competencia, y sexo con niveles de actividad física. Palabras clave: Ejercicio, Educación Física, adolescentes, motivación. The aim of the research was to find out the levels of physical activity and satisfaction of Basic Psychological Needs in adolescents from the Siberia region of Extremadura, to analyse the differences according to sex, as well as to analyse the relationship between levels of physical activity, satisfaction of basic psychological needs and sex. The sample consisted of 204 subjects (92 boys, 112 girls) aged between 10 and 16 years. The Assessment of Physical Activity Levels Questionnaire (APALQ) and the Basic Psychological Needs in Physical Education (BPN-PE) scale were used to assess basic psychological needs. The results showed levels of physical activity (moderately active level, very close to sedentary level) and basic psychological needs that were not very high. By gender, it was observed that girls had a sedentary level of physical activity compared to the moderately active level of boys. Specifically, significant differences were found in the levels of physical activity and competence according to gender. Thus, the male sex felt more competent and performed higher levels of physical activity than the female sex. Furthermore, it was observed that gender, physical activity and satisfaction of basic psychological needs were related to each other. The positive and significant correlation between gender and competence, physical activity levels and competence, and gender and physical activity levels was found to be significant.

Over the past few decades there has been great interest in the study of cognitive processes, and specifically decision-making, from a cognitive perspective. The aim of the present study was to systematically review the scientific literature on the effect of decision training interventions/programs, from a cognitive perspective, on the decision-making of volleyball players. The systematic search was carried out in five scientific electronic databases according to PRISMA guidelines Web of Science (WOS), Pubmed (Medline), Scopus, SportDiscus and Google Scholar. A total of eight studies met the inclusion criteria. The main finding of the meta-analysis was that the use of decision-making training programs/interventions led to significant improvements in volleyball players’ decision-making (Standardized mean difference = 0.94 with 95% confidence interval from 0.63 to 1.25), compared to normal active volleyball training. In addition, the heterogeneity of the interventions was low (I² = 0%). From the results of the studies analyzed, we recommend using decisional interventions or training, both as part of normal active training or complementary to it, to improve the decision-making of the players, thus optimizing their ability to perceive and process relevant stimuli, and then generate quick and effective responses. These findings can be useful in the process of sports training.

The aim of this investigation was to establish the criteria of service, reception and set that determine setting efficacy in world-class top-level volleyball. The study sample consisted of 4.113 gaming actions (1.371 serve actions, 1.371 reception actions, and 1.371 set actions), corresponding to the observation of four matches for each of the 12 best ranked teams in the Volleyball World Championship - a total of 23 matches. The criteria were: in-game role of the server, serve zone, type of serve, striking technique and serve direction; receiver player, reception zone, and reception efficacy; setting zone, type of set, setting technique, setting efficacy, a set’s area, and set tempo. Multinomial logistic regression showed that criteria related to reception (reception efficacy) and to set (setting zone, type of set, a set’s area, and set tempo) determined set efficacy. Specifically, positive and negative receptions and settings from acceptable and non-acceptable zones reduced perfect setting. In contrast, the jump set toward zones three and six and the first and second tempo increased perfect setting. Serve criteria did not determine set efficacy. This study can guide trainers and players in the training process.

El objetivo de estudio fue comparar el comportamento visual (número y duración de las fijaciones visuales) y la toma de decisiones (TD) en el análisis de escenas de ataque en voleibol, entre entrenadores y jóvenes jugadores. Participaron 59 sujetos - 34 entrenadores (M=32.5; DT=9.4) con experiencia como jugadores y entrenadores de voleibol (M=16.78; DT=11.09), y 25 jugadores (M=16.9; DT=1) con experiencia como jugadores de voleibol (M=3.72; DT=1.17). Para el análisis de la calidad de la TD se emplearon las escenas de ataque del Test de Conocimiento Táctico Declarativo en Voleibol (TCTD:Vb). Para el análisis del comportamiento visual se utilizó el Eye Tracking SMI RED500® durante el análisis de las escenas. Los resultados muestran diferencias significativas en la duración de las fijaciones siendo mayores en el grupo de los entrenadores. Concluye que existe un patrón similar de comportamiento visual em la comparación entre los grupos unicamente diferenciado por la duración de las fijaciones visuales.

PARTICIPACIÓN E INFLUENCIA DEL LÍBERO EN RECEPCIÓN Y DEFENSA, EN VOLEIBOL JUVENIL

El objetivo del presente estudio fue conocer la percepción del staff técnico de un equipo de voleibol de alto nivel de la viabilidad, contextualización y utilidad, de una herramienta tecnológica, con posibilidad de acceso desde dispositivos móviles, empleada para almacenar e intercambiar información. La muestra estuvo formada por el staff técnico de un equipo de voleibol femenino que compite en alto nivel, compuesto por un entrenador y un entrenador asistente con funciones de preparador físico. El uso de la herramienta tecnológica, por el equipo, se realizó durante una temporada (siete meses). La herramienta tecnológica consta de una página web y su aplicación con acceso directo a la información desde dispositivos móviles. Como técnica de recogida de datos, se empleó la entrevista semiestructurada al terminar la temporada. El análisis de los datos se realizó a través de la Grounded Theory. Nuestros resultados indican que el staff técnico considera dicha herramienta tecnológica como viable, contextualizada y útil, permitiendo organizar, estructurar e intercambiar información de forma sencilla. Además, los resultados destacan que la posibilidad de acceso mediante un dispositivo móvil tiene grandes ventajas (acceso desde cualquier lugar y en cualquier momento), y alguna desventaja como la posible pérdida de contacto humano.

In the present study, athletes from an elite female volleyball team (N = 12) experienced an intervention programme, based on the provision of information from match analyses, throughout a single season. The information provided related to individual and team competitive performances, as well as the performances of opposition teams. Our aim was to assess the study athletes’ perceptions of this intervention once the season had ended. We used a semi-structured interview method and a thematic analysis of interview content using the categorisation and coding procedures. Regarding the match analysis related to the study team, 95.65% of the comments made by the players were positive and only 4.34% was negative. Players indicated it was useful to understand the negative aspects of their game in order to correct them, and positive aspects in order to motivate weekly training. All of the comments regarding match analyses of opposition teams were positive, with one highlight being that this helped players to be informed about the oppositions’ game and to be more prepared for upcoming matches.

The objective of the research was to analyse the variables predictors of the setting efficacy in the defence complex (KII), in youth athlete, in both genders. The study sample was comprised of 2.404 game actions, 1.104 in the male gender and 1.300 in the female gender. The actions were carried out by the 34 teams that participated in the Spanish Under-16 Championship. The dependant variable was the setting efficacy. The results determined that, in both genders, the dig efficacy, setting technique and the participation in block predicted the setting efficacy; in male gender, the defence zone and tempo of set; no predictor variables were exclusive to the female gender. This information may be relevant when developing training processes in volleyball.
