- PublicationOpen AccessAn analysis of hemoglobin levels and body fat percentage on leg power in volleyball athletes(Servicio de Publicaciones. Universidad de Murcia, 2025) Handaka, Riky Dwi; Majid, Nur Cholis; Miftachurochmah, Yulvia; Fauzi; Sin departamento asociadoThis study aimed to determine the possible relationship between fat percentage and hemoglobin levels on leg power levels. It employed an analytical observational design using a cross-sectional approach. The sampling technique applied was purposive sampling, with the sample studied involving 24 male volleyball athletes aged under 22 years. Hemoglobin was assessed using the cyanmethemoglobin method. Body fat percentage was measured using Bioelectrical Impedance Analysis with the Omron Karada Scan HBF-358, while leg power was evaluated using the vertical jump test. The results indicated a strong negative relationship between the percentage of body fat and leg power (p=0.002; r=-.610), and a strong positive relationship between hemoglobin levels and leg power (p=0.001; r=0.613). The study demonstrated that a higher body fat percentage is associated with high power levels. In contrast, elevated hemoglobin concentrations are also positively related to power, indicating that both oxygen-carrying capacity and body composition may influence muscular performance.

- PublicationOpen AccessAnalysis of the amount of lost fluids, some blood components and mineral salts in volleyball under hot weather conditions(Universidad de Murcia, Servicio de Publicaciones, 2023) Badwi Shbeeb, Huda; Saeed Almousawi, Suhad Qasim; Mousa Jawad, SundusThe research objective was to study the amount of lost fluids, some blood components and mineral salts in volleyball players under hot weather conditions. The sample of the present study was composed of 12 volleyball players of Al-Sinaa Club (Baghdad, Iraq) in the 2022/2023 season. The variables analyzed in this study were: Heart rate before and after exercise, internal and external body temperature before and after exertion, potassium ion, sodium ion, calcium ion, and the amount of fluid lost (the player's weight) before and after the exercise. The tests were conducted at a temperature between 42-47 degrees Celsius. The maximum anaerobic exercise was performed with volleyball. The results showed that to play volleyball under hot weather conditions (42-47 degrees Celsius) significantly increased the following variables in volleyball players: heart rate, external body temperature, internal body temperature, sodium ion and calcium ion. However, potassium ion significantly decreased. Therefore, training in hot weather has positive physical repercussions. The authors recommend to train in different weather conditions.
- PublicationOpen AccessBehavioral intentions, satisfaction and perceived quality of the spectators of the 2017 Asian Men’s U23 Volleyball Championship(Universidad de Murcia. Servicio de publicaciones, 2021) Naghi-Pour Givi, Behnam; Hossein Monazzami, Amir; Mohamadi Turkmani, Ehsan; Mirfallah Nassiri, RezaThe aim of this study was to analyze behavioral intentions, sa-tisfaction and perceived quality of the spectators of the 2017 Asian Men’s U23 Volleyball Championship. The sample was composed of 351 specta-tors of the event. The instrument used was a reliable questionnaire with five sub-questionnaires about service quality, main product quality, servi-ce satisfaction, game satisfaction, and behavioral intentions. The statisti-cal analysis was based on structural equations and it was carried out with the software WarpPLS version 6. The quality of services had a significant effect on service satisfaction (β=0.504, P<0.001). The core product quality had a significant effect on game satisfaction (β=0.658, P<0.001). Also, the game satisfaction had a significant effect on behavioral intentions (β= 0.514, P<0.001). However, the effect of service satisfaction on behavioral inten-tions was not significant. Therefore, it is recommendable that the organizers of mega sport events consider these results in order to improve the behavio-ral intentions, satisfaction and perceived quality of the spectators.

- PublicationOpen AccessEl comportamiento visual de bloqueadoras juveniles de voleibol y su relación con la precisión de su respuesta(Murcia: Servicio de Publicaciones de la Universidad de Murcia, 2015) Sáez Gallego, Nieves María; Vila Maldonado, Sara; Abellán Hernández, Jorge; Contreras Jordán, Onofre RicardoEl presente estudio examina el comportamiento visual de jóvenes jugadoras de voleibol en la acción del bloqueo. El objetivo fue analizar las estrategias de búsqueda visual y las principales localizaciones de las fijaciones en el transcurso de la acción, estableciendo relaciones entre éstas y el porcentaje de aciertos. 29 jugadoras de voleibol (17,4 ± 0,9 años de edad) debían decidir la dirección de la colocación durante la visualización de secuencias de vídeo proyectadas a tamaño real. Se registraba su decisión mediante el movimiento de las jugadoras, que fue grabado por una cámara de vídeo a 25 fps y se analizó fotograma a fotograma. El comportamiento visual de las jugadoras se obtuvo mediante un sistema de seguimiento de la mirada (Mobile Eye de ASL), y se analizó en función de las dos direcciones de la colocación: zona 3 y zona 4. Se calculó el coeficiente de correlación de Pearson entre el Porcentaje de aciertos totales y las diferentes variables de comportamiento visual, y se aplicó la estadística inferencial para comprobar las diferencias en función de la zona. Las jugadoras estaban más sincronizadas con la información relativa al balón que con la contenida en la colocadora, siendo esa la fuente de información en la que principalmente basaron sus decisiones. La fijación de la zona Balón-Muñeca en los momentos cercanos al contacto puede ser la clave para lograr una correcta anticipación en esta acción, ya que permitiría extraer información del balón y del brazo de la colocadora al mismo tiempo mediante la visión periférica.
- PublicationOpen AccessConstruction and application effect of coach competency model in volleyball(Universidad de Murcia, Servicio de Publicaciones, 2024) Wang, Danyi; Bo, XuesongConstructing a competence model for volleyball coaches tailored to school characteristics has recently gained importance. This study aimed to clarify the competency model construction and its application effect. The study developed a volleyball coach competence model centered on knowledge, skills, professional roles, attitudes, and motivation. A quantitative methodology was used to assess the relationships between these dimensions and coaching performance, emphasizing teaching quality and overall effectiveness. The model drew from theoretical frameworks, including the Iceberg Model and the Onion Model. The sample consisted of 120 volleyball coaches. The correlation analysis revealed significant relationships among knowledge competence, skill competence, professional role, work attitude, work motivation, educational process factors, and educational target factors (pY1 < 0.05, pY2 < 0.05, and r > 0.1). The regression results indicated that gender, professional title, knowledge competence, professional competence, professional role, and work attitude positively influenced the achievement of the competency application effect (p < 0.05 and β > 0). In contrast, work motivation, age, teaching experience, education level, and salary showed no statistically significant impact (p > 0.05). Volleyball coaches' competence is essential for effective teaching and training, directly enhancing athletes' skills and performance. The model also improves coaches' quality and application ability, leading to increased athlete satisfaction and better training outcomes.

Servicio de publicaciones, 2022) Salam Ibrahim, ReemTo achieve high level of performance in sports games and events, all aspects, including the motor, tactical, psychological and skill performance of the players must be integrated and improved. Rubber bands play an important role in player rehabilitation to speed up muscle recovery in a good way. The aim of the study was to prepare a rehabilitation skill program using rubber bands to develop the preparation skills and biokinetic variables for volleyball players with disabilities in wheelchairs. The experimental method was used in one of its basic designs which is the design of the two equivalent groups, this due to the suitability of this design to the nature of the research problem. The research sample was chosen by a comprehensive inventory method and consisted of 18 disabled volleyball players of Babylon governorate for the 2021 season. The sample was divided into two groups, the experimental group and the control group, with 9 players for each group. A rehabilitative skill program was prepared using rubber bands on the experimental group for a period of eight weeks, with three training units per week. Data were analyzed based on arithmetic means, standard deviations and t-test. As a result, statistically significant differences were found between the pre-test and post-test of the experimental group and the control group for all study variables, in favor of the post-test for both groups (p<0.05). In conclusion, the rehabiliation skill program using rubber bands has a positive effect on the development of the preparation skills and biokinetic variables for volleyball players with disabilities in wheelchairs.
- PublicationOpen AccessEffect of repeated use of social media before training sessions on countermovement jumping and internal training load in high-level volleyball players(Universidad de Murcia. Servicio de publicaciones, 2024) Freitas Junior, Carlos; Berriel, Guilherme; Faro, Heloiana; Peyré Tartaruga, Leonardo; Fortes, LeonardoTo verify the effect of repeated use of social media on smartphones immediately before countermovement jump (CMJ) and internal training load (ITL) training sessions in young male high-level volleyball athletes. 18 young international-level athletes participated in a randomized crossover study for a total of two weeks. The athletes are from the Brazilian under-19 team and were randomized into two experimental conditions, social media (SMA) and control (CON). SMA used social media for 30 minutes before training sessions for a week, while CON watched emotionally neutral videos. During this period, the ITL was analyzed using the session rating of perceived exertion (s-RPE) method. The CMJ was analyzed before, between, and after the two-week training. In the second week, the athletes reversed the experimental conditions. The CMJ was decreased after the training week (p =0.04), but with no difference between the experimental conditions (p = 0.51). The ITL was not different between the experimental conditions after the analyzed training week (p = 0.95). Repeated use of social media on smartphones immediately before training sessions for a week was not enough to harm the CMJ, nor did it increase the ITL in young international-level volleyball athletes.
- PublicationOpen AccessThe effect of self-regulated feedback on acquisition and learning the overhand service skill of novice female athletes in volleyball(Murcia: Servicio de Publicaciones de la Universidad de Murcia, 2018) Zetou, Eleni; Vernadakis, N.; Mountaki, F.; Karypidou, D.Abstract: The purpose of the present research was to study the effect of self- regulated feedback on the acquisition and learning of the volleyball over- hand service skill in novice female players 10-11 years old. Twenty-eight (28) novice female athletes aged 10-11 years old and with a 2- year training experience participated in this study. The female athletes were randomly divided into two groups, the experimental (n=14) and the control group (n=14). The athletes of both groups followed a five week training program with two units per week, which included drills for the learning of the servi- ce skill. The athletes of the experimental group were able to ask for feedback whenever they wished, while the athletes of the control group followed the program for learning the skill, taking feedback (knowledge of performan- ce), whenever it was considered necessary by the coach. The results showed that there were significant differences between the two groups in learning the skill. Specifically, the experimental group was better at all the elements of the service skill, except for the throw of the ball, which apparently is due to lack of coordination of athletes at this age. It is suggested that coaches can use the self-regulated feedback, for better performance and learning and to develop athletes’ internal cognitive processes.
- PublicationOpen AccessEffects of a training method on 13-14-year-old female volleyball players in Tirana, Albania(Servicio de Publicaciones. Universidad de Murcia, 2025) Lleshi, Enkeleida; Martiri, Altin; Mema, Blerina; Sin departamento asociadoThe aim of this study was to improve skill indicators in female volleyball players of Tirana in Albania, with a real-time training model of 15 min. A total of 30 female volleyball players, aged 13-14 years (13.0±0.6 years), was divided into two teams: the experimental team (N = 15) and the control team (N = 15). The study was conducted from September to December 2023. During this period of time, the experimental team underwent a 15-minute training intervention, 3 times a week, while the control team followed the coach’s standard training program. Participants were subjected to anthropometric measurements, including body height, body weight, and Body Mass Index (BMI). Subjects were also tested on Squat Jump (SJ), Counter Movement Jump (CMJ), 20-cm Drop Jump (DJ), Agility Test, Lateral Change of Direction, T-Test, Shuttle Run Test (10 x 5 m) and Hexagonal Test. The tests were conducted before and after the implementation of the intervention training program. The linear effect of the intervention was statistically significant [F (1,22) = 53.797, p<0.001)], indicating that there is a significant difference across levels of intervention. The findings from this study suggest that the applied methodology is effective in comparing performances, enabling trainers to design real-time training programs for developing specific physical components based on existing conditions.
