The present study examined selected kinematic characteristics analysis of knee and ankle joints during block jump in elite junior volleyball players. Methods: Thirty male junior elite volleyball players (Mean±SD age: 18.14±1.12 y, height: 197.10±3.16 cm, sports history: 4.39±0.95 y, & weight: 771.20±59.83 N) participated in this study. A time-synchronized 5-camera sampling at 100 Hz was used to determine the Three Dimensional (3D) coordinates of markers. Kolmogorov-Smirnov test, linear regression, and magnitude of coefficient were used in SPSS to analyze the obtained data (P<0.05). Results: The Mean±SD height of block jump was 45.5±2.06 cm, and the Mean±SD angles of knee and ankle flexion were 93.37±4.75 and 21.25±2.98 cm, respectively. Moreover, there was a negative relationship between knee and ankle flexion angle and block jump height (-0.051,-0.054, respectively) (P<0.05). However, smaller knee flexion angles had more negative effect on block jump height (0.741) (P<0.05). Conclusion: The study results could be used by coaches as a simple tool in jumping performance among junior volleyball players. The obtained data could also be beneficial in the efficient control of applied training procedures.

Effect of an Arm Swing on Countermovement Vertical Jump Performance in Elite Volleyball Players
Journal of Human Kinetics, 2016
The aim of this study was to determine how elite volleyball players employed the arm swing (AS) to enhance their jump performance. The study assessed how the AS influenced the duration and magnitude of the vertical ground reaction force (VGRF) during the main phases (preparatory, braking and accelerating) of the countermovement vertical jump (CMVJ), the starting position of the body at the beginning of the accelerating phase and the moment when the AS began contributing to increasing the jump height. Eighteen elite volleyball players performed three CMVJs with and without an AS. Kinetics and kinematics data were collected using two Kistler force plates and the C-motion system. The time and force variables were evaluated based on the VGRF, and the position of the body and the trajectory of the arm movement were determined using kinematic analysis. The AS improved the CMVJ by increasing the jump height by 38% relative to jumping without an AS. The AS significantly shortened the brakin...
Aspects of a Three Dimensional Motion Analysis of the Volleyball Spike in High Level Competition
2007
The purpose of the study was a three dimensional motion analysis of the volleyball spike from position four during competition. Spikes were analysed at a tournament of the European league. Regarding the jump technique, only few athletes performed the discussed coordination pattern of the impulses within the body. It may be concluded that there exists reserves within the training process concerning the coordination in the takeoff phase even in high level athletes.
Kinematical Analysis of Female Volleyball Spike
Proceedings of the 26 th International …, 2008
The purpose of this study was to analyze female volleyball players' body centre of mass (CM) displacement and velocity when spiking at front and back row. Six high school players participated in this study. Two JVC9800 digital video cameras (120Hz) were used to collect spiking motion. Kwon 3D motion system was used to analyze the kinematic variables. The results indicated that the back-row spike had greater CM resultant velocity at approach and take-off than front-row spike. The back-row spike had greater jumping height and the CM horizontal displacement than front-row spike. The initial ball velocity and angular velocity of shoulder, elbow, and wrist of the front-row spike were greater than back-row spike. This study provides information for coaches in teaching volleyball spike.
This study examined pilot data exploring approaches to testing whether the existing explanation about the biomechanics of hang-time in a basketball jump shot proposed by Bishop and Hay (1979) is applicable for spike jumps in volleyball and to identifying possible additional factors that could have an influence on hang-time in volleyball. Kinematics of spike jumps of volleyball players (n=3) using a technique that would theoretically increase hang-time were compared to jumps using a technique that would theoretically decrease it. The results suggested that the mechanisms creating hang-time in volleyball spike jumps are not the same as those in a basketball jump shot. These results suggested that the leg contributions are different and that the motion of the trunk also contributes to hang-time. INTRODUCTION: In volleyball, hitting spikes is the primary way of scoring points and winning. Great extensor physical strength is required to jump high enough to clear the block and to hit the ball hard enough to avoid defensive players. But extensor physical strength is only important when the athlete is on the ground and pushes against it in order to jump high. Once the athlete is in the air, movement of the athlete's body segments is what determines the success of the performance. The only major force on the body while the athlete is in flight is gravity. This means that the center of mass of the athlete follows a parabolic trajectory governed by Newton's laws and so motion of the segments of the body interact with each other. By voluntarily controlling the motion of certain segments, the athlete also affects the motion of other segments, which can potentially enhance performance.
AN ANALYSIS OF THE DIFFERENT SPIKE ATTACK ARM SWINGS USED IN ELITE LEVELS OF MEN'S VOLLEYBALL
As part of this work, two preliminary studies were conducted that identified three possible swings used at the elite level of volleyball and the resulting ball velocities created using these swings. Therefore, the purpose of this work was to explore the kinematic aspects of the different spike attack arm swings (straight ahead (SA), cross body (CB) and outside (OS)) where each different swing was broken down into its constituent parts.

are types of vertical jumps, and constitute the most useable tests for the assessment of the neuromuscular coordination of athletes (Claudino et al., 2017). In addition, CMJ is used for the assessment of the fitness level of injured athletes after rehabilitation periods, and for detecting their fitness to return to play (Clanton, Matheny, Jarvis, & Jeronimus, 2012; Henderson, Barnes, & Portas, 2010; Olsson et al., 2013). Forcetime (F-T) curve variables of CMJ are utilised to assess neuromuscular and biomechanical features related to lower extremity dynamics (Claudino et al., 2017; Kollias et al., 2001). Additionally, vertical jump tests are performed in accordance to various aims, such as the assessment of the developed force and power in elite athletes who participate regularly in competitions (Cormie, McGuigan, & Newton, 2010). McGinnis et al. (2016) have used CMJ to assess the effect of fatigue on performance. Olsson et al. (2013) showed that CMJ and other types of jumps could be used for the assessment and evaluation of athletes' performances, after Achilles tendon tears. Previous research studies have shown that CMJ has an appropriate validity for assessing explosive
The Effect of Approach on Spike Jump Height for Female Volleyball Players
International Journal of Sports Science & Coaching, 2010
The purpose of the study was to compare vertical jump height using a four-step approach volleyball spike jump (VBSJ) and a standing counter-movement jump (CMJ) for competitive female volleyball players. Ten NCAA Division I female volleyball players were recruited. Each participant performed jumps using two techniques: a four-step approach VBSJ and a standing CMJ. Mean jump height for the VBSJ (0.38 ± 0.06 m) was significantly greater than the CMJ (0.33 ± 0.05 m). No correlation between jump height and horizontal center of mass (CoM) velocity during the VBSJ approach was found. The results indicate that a four-step approach benefits jump height for elite female volleyball players. However, approach velocity is not a determining factor that makes a four-step approach more beneficial. Other characteristics, such as improved force development and power production may better explain the benefit of the VBSJ approach for female volleyball players.
