ABSTRACTSattler, T, Hadžić, V, Dervišević, E, and Markovic, G. Vertical jump performance of professional male and female volleyball playerseffects of playing position and competition level. J ...Strength Cond Res 29(6)1486–1493, 2015—Vertical jump (VJ) performance is an important element for successful volleyball practice. The aims of the study were (a) to explore the overall VJ performance of elite volleyball players of both sexes, (b) to explore the differences in VJ performance among different competition levels and different playing positions, and (c) to evaluate the sex-related differences in the role of the arm swing and 3-step approach with arm swing on the jump height. We assessed the VJ capacity in 253 volleyball players (113 males and 140 females) from Slovenian first and second Volleyball Division. The height of squat jump (SJ), countermovement jump, block jump, and attack jump was tested using an Optojump system. We observed significant differences (p ≤ 0.05) in VJ height between different levels of play that were most pronounced in the SJ. Position-related differences in VJ performance were observed in male players between receivers and setters (p ≤ 0.05), whereas in females, VJ performance across different playing positions seems equal. Finally, we found that male players significantly better use the arm swing during VJ than females (p ≤ 0.05), whereas the use of eccentric part of the jump and approach before the spike to improve VJ performance seem to be equally mastered activity in both sexes. These results could assist coaches in the development of jumping performance in volleyball players. Furthermore, presented normative data for jump heights of elite male and female volleyball players could be useful in selection and profiling of young volleyball players.

Explosive lower body strength in volleyball is a constant challenge for every coach and physical trainer who is involved in training a team. The concern is mostly important not only due to the ...vertical jump but also due to the movement in the field. During the game of volleyball, because of the small dimension of the court, the first 2-3 steps, the starting steps are crucial in the successful execution of each phase during the game. Methods. To determine the area of interest in a representative volleyball team, we applied two tests using the optojump device, as follows: 15 sec jumps test and 30 sec jumps test. Objective. These two tests were performed at the beginning of the training season in order to see the level of explosive strength parameters Results. These parameters were analyzed for each subject, as well as for the entire tested team. The average height reached by the center of gravity for the entire team during the 15 sec jumps test is 20.1 cm, while the average jumps in the 30 sec jumps test is 16.6 cm. Analyzing the explosive force parameters shows the direction in which the team’s physical training should be designed. Keywords: volleyball, optojump, explosive power
Background. Training programs are part of training management that need to be properly and correctly prepared and implemented. Study Purpose. The aim of the study was to evaluate the effects of an ...8-week program of resistance training, carried out at a specific preparation phase, on the performance of male junior volleyball athletes. Materials and methods. This study was conducted as experimental research, with a sample of 24 male volleyball athletes (mean ± SD age: 17.96 ± 1.23 years; body weight: 75.56 ± 7.80 kg; height: 180.46 ± 7.14 cm; body fat: 17.62 ± 3.36%) who were randomly divided into experimental group (EG): n = 12 and control group (CG): n = 12. The training program lasted for eight weeks and took place at a specific preparation phase. Results. There was a significant increase in the indicators handgrip dynamometer left (p<0.014), handgrip dynamometer right (p<0.001), vertical jump (p<0.001), sit-and-reach test (p<0.000), leg dynamometer (p<0.000), and back dynamometer (p<0.001) in the experimental group after being given strength training treatment for eight weeks. Conclusions. When strength training is included in volleyball training, it can increase the performance in power, strength, and flexibility, especially when carried out at a specific preparation phase. Incorporating targeted stimuli, such as strength training, into training sessions appears to be a secure method of training for this age group and may help to contribute to continuous and gradual improvements in neuromuscular adaptation.
In elite volleyball, the serve takes an offensive form, aiming to directly score a point or significantly hinder the opponent from launching an attack. Which is why the research aimed to compare the ...type and effectiveness of the serve in the main round of Tauron and PlusLiga in the 2021/2022 season and update the current knowledge on the types of serves by function and gender. The study analysed observation consisted of 314 women’s and men’s matches. VolleyStation Pro v 1.29.5; Volleystation z o. o. Poland. Data from the main round matches that took place in the 2021/2022 season in the Polish elite league PlusLiga (182 men’s matches) and Tauron Liga (132 women’s matches) were used, and the regular season consisted of 2 rounds. The average percentage effectiveness of the serve in women was higher (E = 22%) than in men (E = 15%). In women, only 3 types were observed (JS, JF and W), as much as 86% of all the serves were JF serves. In men, as many as 5 types (JS, JF, FJS, FJF and W), of which over 67% were dynamic JS serves (jumping serve). The serve element has been modified over the years to obtain better effects conducive to winning. Ranging from increasing the speed of the serve, eliminating the serves from the spot in favor of the jump serves, to the use of serves to hide the correct hit of the ball (“Fake”—FFJ, FJS).
Training volume and body composition have been suggested as risk factors for jumper's knee among athletic youth, but research is lacking. The aim of this 4‐year prospective cohort study was to ...examine the relationship between training and competition load, body composition, and risk for developing jumper's knee. Participants are elite volleyball players, aged 16–18 years. Training and competition load was recorded continuously and body composition semiannually. Jumper's knee was diagnosed on a standardized clinical examination. We recruited 141 healthy students (69 males and 72 females), and 28 developed jumper's knee (22 boys and six girls). In a multivariate analyses, boys had three to four times higher risk compared with girls. Volleyball training had an odds ratio (OR) 1.72 (1.18–2.53) for every extra hour trained, and match exposure was the strongest sports‐related predictor for developing jumper's knee with an OR of 3.88 (1.80–8.40) for every extra set played per week. We did not detect any significant differences between the groups in body composition at the time of inclusion or in the change of body composition during the study period. Conclusion, male gender, a high volume of volleyball training and match exposure were risk factors for developing jumper's knee.

Objetivo: determinar la relación entre el tipo de recepción, el tiempo de ataque, el tipo de ataque y la dirección de ataque con el resultado final del remate del central en una pierna por las zonas ...del campo establecidas como “A”, “B” y “C” por el Sistema Diagonal Combinado. Método: se analizaron por vídeo 269 acciones de ataque de varios partidos femeninos del Eurovolley 2017. Resultados: los resultados mostraron que existe una relación positiva entre el tipo de recepción, el tiempo de ataque, el tipo de ataque y la dirección del ataque con el resultado final del remate. Por otro lado, el ataque más efectivo es realizado después de una recepción doble positiva y, en segundo lugar, después de una defensa. La velocidad de ataque que mayor coeficiente de rendimiento obtuvo es al primer tiempo. En cuanto al tipo de ataque, el “fast” fue el que mejor resultado obtuvo, pero también con el que más errores se cometieron, si se compara con el “gancho” y la “slide”, mientras que la zona de ataque más efectiva fue el remate que va dirigido hacia zona 6. El remate a la diagonal obtuvo resultados similares en los puntos conseguidos que el remate a la línea, pero con un menor porcentaje de error. Conclusiones: el ataque después de una recepción doble positiva, el ataque al primer tiempo, el remate a la diagonal y el remate “fast” fueron las acciones con las que se obtuvo mejor rendimiento deportivo y provocó una mayor desorganización defensiva rival.

Abstract. Objective: to determine the relationship between the type of reception, the time of attack, the type of attack and the direction of attack with the final result of the central shot on one leg through the areas of the field established as "A", "B" and "C" for the Combined Diagonal System. Methods: 269 attack actions from various Eurovolley 2017 women's matches were analyzed by video. Results: the results showed that there is a positive relationship between the type of reception, the time of attack, the type of attack and the direction of the attack with the final result of the shot. On the other hand, the most effective attack is made after a positive double catch and, secondly, after a defense. The attack speed that obtained the highest coefficient of performance is at the first half. Regarding the type of attack, the "fast" was the one that obtained the best result but also the one with the most mistakes, if compared with the "hook" and the "slide", while the most effective attack zone was the shot that goes towards zone 6. The shot to the diagonal obtained similar results in the points achieved as the shot to the line but with a lower percentage of error. Conclusions: the attack after a positive double reception, the attack at the first half, the shot to the diagonal and the shot "fast" were the actions with which better sports performance was obtained and caused a greater rival defensive disorganization.

En el voleibol la potencia en las extremidades inferiores es determinante para el rendimiento en acciones como el remate, el bloqueo y el saque en suspensión. Pero, además, para acciones que exigen ...de agilidad como es el caso de los Cambio de Dirección (CDD). El objetivo de este estudio fue examinar la asociación entre la potencia en el salto con sentadilla (SJ), el contramovimiento (CMJ) y la diferencia del SJ-CMJ (SJ-CMJdif) y los CDD en jugadores universitarios de voleibol. En el estudio de diseño transversal, con alcance correlacional, 12 jugadores realizaron las pruebas SJ, CMJ y dos CDD (T-Test, 5-0-5 Test). La potencia del SJ o el CMJ medida en Watios no correlacionó con los CDD. Sin embargo, la altura del SJ (r= - 0.58, p=.04) y CMJ (r= - 0.69, p=.01) tuvieron una correlación negativa y grande con el T-Test, mas no con el 5-0-5 Test. De la misma forma la SJ-CMJdif tuvó una correlación negativa y grande con el T-Test (r= - 0.61, p=.03), pero no con el 5-0-5. Los resultados sustentan la utilidad del SJ y el CMJ para el control de la potencia en los miembros inferiores, destacan la especificidad del T-Test para la evaluación de los CDD en el Voleibol y el aprovechamiento del potencial elástico necesario en las acciones de aceleración y desaceleraciones, evaluado mediante la SJ-CMJdif.

Abstract. In volleyball, the power in the lower extremities is decisive for performance in actions such as spikes, blocks and jump serve. But, in addition, for actions that require agility, such as Change of Direction (COD). The objective of this study was to examine the association between Squat Jump (SJ) power, countermovement (CMJ) power, and SJ-CMJ difference (SJ-CMJdif) and COD in college volleyball players. In the cross-sectional study, with a correlational scope, 12 players executed the SJ, CMJ and two COD tests (T-Test, 5-0-5 Test). The power (Watts) of the SJ or the CMJ did not correlate with the COD. However, SJ height (r= - 0.58, p=.04) and CMJ height (r= - 0.69, p=.01) had a negative and large correlation with the T-Test, but not with the 5-0-5 Test. In the same way, the SJ-CMJdif had a negative and large correlation with the T-Test (r= - 0.61, p=.03), but not with the 5-0-5. The results support the usefulness of the SJ and the CMJ for the control of power in the lower limbs, highlight the specificity of the T-Test for the evaluation of the COD in Volleyball and the utility of the elastic potential in the actions of acceleration and decelerations, evaluated using the SJ-CMJdif.
