Este aspecto puede influir, según diversos expertos, sobre el correcto desarrollo de los jóvenes jugadores. Para ello se observaron 2021 acciones del Campeonato de España Escolar Masculino en categoría infantil. Se estudió la relación entre el saque en suspensión y las posibilidades de construcción del equipo que lo recibe, así como la forma de culminar el punto y el resultado del mismo. Los resultados constataron que el saque en suspensión afectó significativamente a la falta de efectividad en el momento de construir una acción colectiva por parte del equipo receptor, y en la dificultad para que esta construcción culmine en un remate. Por otro lado, no se encontraron diferencias significativas entre la técnica de saque utilizada y el resultado del punto. Todo ello nos invita a cuestionar la idoneidad del saque en suspensión en estas edades.Palabras clave: voleibol; saque en suspensión; ataque; jóvenes jugadores.

España e-mal: aurena@ugr.es The aim of this study, is to observe the jump serve incidence on the attack phase in the under 14 volleyball. This aspect could influence, as the expert shows, on the right young player's development. The study consisted in an observation of 2021 plays during the male under 14 Spanish championships. The relationship between jump serve and attack construction possibilities were studied, also the technical way to conclude the point and the result of that play. The results showed a lack of effectiveness to create a team action during the reception phase after a jump serve execution, which means an increase in the difficulty to close the point with a spike or overhead shot. However, the study could not find differences in the comparison of the serve technique and the result of each point. In conclusion, the results bring us to question the jump serve suitability at this age.

Physical activity has been shown to improve the health and well-being of students, athletes and the general population, especially when it is properly monitored and responses are evaluated. However, data are mostly gathered without considering a valuable element, participants’ perceptions. Therefore, the objective was to know the perception of volleyball student-athletes when using different monitoring and response tools that assess well-being, workloads, responses to workloads, and academic demands. A qualitative study using semi-structured interviews with female volleyball student-athletes (n = 22) was used to know players’ perceptions when using a wellness/well-being questionnaire, session ratings of perceived exertion (sRPE), and countermovement jumps (CMJ), and consider academic demands. Results show that the wellness questionnaire and sRPE increased student-athletes’ awareness of well-being and readiness to perform, improved self-evaluation, self-regulation, and self-demand. However, motivation and overcoming challenges were based on the CMJ. Academic demands affected 82% of student-athletes, altering stress, fatigue, and sleep quality. Nonetheless, sport was seen as an activity that helped with academic commitments. Therefore, the wellness questionnaires and the sRPE facilitated self-awareness and positive dispositions toward self-regulation. Simultaneous intensive academic demands and training can produce mutual positive effects if the variables of physical and mental loads are harmonized in the critical academic and sports periods.
