Force Time

The importance of vertical jump in sport fields and rehabilitation is widely recognized. Furthermore, Force-Time variables of vertical jump are factors affecting jumping height. Exclusive review of each of this variables, in eccentric and concentric phases, can lead to a specific focus on them during jumping exercises. So, the aims of his study were to a) reviewing the relationship between force-time curve variables of eccentric and concentric phases with jump height and b) description of this variables in Iran national youth volleyball players society. This is an observational study. 12 elite volleyball player (Male, Iran national youth volleyball players, 17±0.7 years) have participated in this study. Correlation between Force-Time variables - included peak force (PF), relative peak force (RPP), peak power (PP), average power (AP), relative peak power (RPP), and Modified Reactive Strength Index (MRSI) - in eccentric and concentric phases and ultimate jump height has been studied. Results showed that the average power (r=0.7) and relative peak force (r=0.75) of concentric phase and MRSI (r=0.83) have significant correlation with ultimate jump height (JH). Relative peak power and average power of concentric phase can massively effect Jump Height in sports like volleyball, which vertical jump is an integral part of them. Focus on both of these factors, which has been studied in this research, in training programs, can improve athlete jump performance significantly.

In volleyball, spikes, and block jumps are among the most important movements when earning points and impacting performance. Many studies have found a greater jump height after acutely augmented feedback and extrinsic focus of attention on vertical jump height. However, there are limited studies on the long-term effects of using an overhead target on volleyball-specific vertical jumps (block and spike jumps). Therefore, the aim of the current study was to investigate the effects of using an overhead target on the vertical jump heights of volleyball players. Twenty-five professional male volleyball players (age: 24.44 ± 3.78 years; height: 1.82 ± 8.79 cm; body mass: 80.96 ± 9.37 kg) were randomly assigned either to the experimental group with an overhead target (OHT) ( n = 9), group without an overhead target (WOHT) ( n = 10), or the control group ( n = 8). The OHT group performed vertical jumps with an overhead target before their regular training program, while the WOHT group completed vertical jumps without an overhead target before their regular training program. Meanwhile, the control group performed only their regular training program, which was a 5 week (3 days per week) program. All participants’ spike jump (SPJ) and block jump (BJ) results were assessed before and after the intervention. A repeated-measures analysis of variance (3 × 2) did not reveal any significant between-group interactions for SPJ and BJ ( F = 7.32, p < 0.11 and F = 1.59, p < 0.22 respectively), but significant results were found for the time effect ( F = 96.33, p < 0.01 and F = 132.25, p < 0.01 respectively) and group × time interaction ( F = 42.59, p < 0.01 and F = 61.52, p < 0.01, respectively). While the pre- and post-tests for BJ and SPJ values did not change in the control group ( p > 0.05), both of these values increased in the OHT group (60.00 ± 5.95–67.44 ± 5.98 cm, p < 0.01 for d = 1.24 and 49.00 ± 6.74–56.22 ± 5.29 cm p < 0.01 for d = 1.19, respectively) and WOHT group (57.50 ± 4.86–60.50 ± 4.99 cm, p < 0.01 for d = 0.60 and 47.75 ± 4.65–50.25 ± 3.69 cm, p < 0.01 for d = 0.59). It has been suggested that trainers and professionals can use an overhead target to increase the BJ and SPJ heights of professional volleyball players.

Jump Ability

The aim of this study was to describe the effects of 6 weeks of combined strength and jump training which incorporated moderate loads and high intensity contractions on the vertical jump ability (VJ), loaded jumps and velocity of execution in full squat in a group of professional male volleyball players during the competition season. It was hypothesized that the VJ improved by cross combined strength and jump training both characterized by high velocity of execution (>1m/s). The participants in this study were twelve players who competed in the first national division of the Spanish National League during the 2011-2012 season. The neuromuscular performance was estimated by unloaded (CMJ) and loaded countermovement jumps (CMJloaded) height (cm); and by velocity of displacement in the concentric phase of full squat (FS) (m/s). There was a significant increase in CMJ and CMJloaded after 6-week of training (5%, p<0.01; and 5.7%, p<0.05; respectively). These changes were accompanied by a small and moderate value of Effect Size (0.47, and 0.67; respectively). No significant differences were observed for velocity of displacement in FS. The linear correlation analysis showed a single moderate correlation statistically significant between the changes in CMJ-CMJloaded and CMJ-FS (r=0.62 and r=0.59, p<0.05; respectively). Albeit speculative, our results suggest that the use of moderate loads could be enough to improve the vertical jump performance, since in our study a load equivalent to 60% 1RM in the FS was not exceeded and jumping exercises were performed with light loads.Keywords: Resistance training; Plyometric exercise; Vertical jump; Lower Extremity, Velocity, Strength.Resumen: El objetivo de este estudio fue describir los efectos de 6 semanas de entrenamiento combinado de fuerza y salto, el cual incorpora cargas moderadas e intensidades de contracción altas, sobre la capacidad de salto vertical, saltos con cargas y la velocidad de ejecución en el ejercicio de sentadilla en un grupo de jugadores profesionales de voleibol durante la temporada de competición. Se estableció la hipótesis de que el salto vertical mejoro por el uso combinado de entrenamiento de fuerza y salto, ambos caracterizados por una alta velocidad de ejecución (>1m/s). El rendimiento neuromuscular fue estimado por la altura (cm) del salto sin cargas (CMJ), salto con cargas (CMJloaded), y por la velocidad (m/s) de desplazamiento en la fase concéntrica en la sentadilla completa (FS). Tuvo lugar un incremento significativo en CMJ y CMJloaded después de 6 semanas de entrenamientos (5%, p<0.01; y 5.7%, p<0.05; respectivamente). Estos cambios fueron acompañados por un valor de Tamaño del Efecto pequeño y moderado (0.47, and 0.67; respectivamente). No se observaron diferencias significativas en la velocidad de desplazamiento en FS. El análisis de correlación lineal mostró una correlación moderada estadísticamente significativa entre los cambios en CMJ-CMJloaded y CMJ-FS (r=0.62; y r=0.59, p<0.05; respectivamente). Aunque algo especulativo, nuestros resultados sugieren que el uso de cargas moderadas podría ser suficiente para mejorar el rendimiento del salto vertical, ya que en nuestro estudio no se excedió una carga equivalente al 60% de 1RM en FS y los ejercicios de saltos también fueron realizados con cargas ligeras. Palabras claves: Entrenamiento con resistencias, ejercicios pliométricos, salto vertical, extremidad inferior, velocidad, fuerza.

Objective: Aim of this study was to investigate the combined and comparative training outcomes of plyometrics and dynamic stretching of lower limb muscle groups on vertical jump performance in male and female collegiate volleyball players. Materials and Methods: The study was carried out as two training sessions in a week, for eight weeks duration. The total number of participants was 90 male and 90 female collegiate volleyball players aged 18-22 years. All the participants were recreational players and they were playing one hour daily in the evening. They were randomly distributed into three male groups (Group 1, Group 2 & Group 3) and three female groups (Group 4, Group 5 & Group 6) with 30 participants in each group. All the participants underwent Sargent vertical jump performance test before starting the training session it was repeated in every two weeks of training program. Results: Plyometrics and plyometrics with dynamic stretching led to significant improvements in vertical jump height (VJH), and this improvement was progressed after every two weeks of training. However, the control groups did not display any improvement. The effect of training was significantly higher in male and female groups who have performed plyometrics with lower limbs dynamic stretching as compared with the groups that performed only plyometric exercises (p<0.05). Compared to females, male participants had a better improvement of VJH in both training groups (p<0.05). Conclusion: It can be concluded that two sessions of plyometric exercise training per week for eight weeks can improve the ability of VJH in male and female collegiate volleyball players. However, combined training of lower body plyometrics and lower limbs dynamic stretching had better results in terms of vertical jump performance.
