Volleyball players are at high risk of overuse shoulder injuries, with spike biomechanics a perceived risk factor. This study compared spike kinematics between elite male volleyball players with and without a history of shoulder injuries. Height, mass, maximum jump height, passive shoulder rotation range of motion (ROM), and active trunk ROM were collected on elite players with (13) and without (11) shoulder injury history and were compared using independent samples t tests (P < .05). The average of spike kinematics at impact and range 0.1 s before and after impact during down-the-line and cross-court spike types were compared using linear mixed models in SPSS (P < .01). No differences were detected between the injured and uninjured groups. Thoracic rotation and shoulder abduction at impact and range of shoulder rotation velocity differed between spike types. The ability to tolerate the differing demands of the spike types could be used as return-to-play criteria for injured athletes.

The Fédération Internationale de Volleyball (FIVB) has hitherto received inadequate public, media, or scholarly inquiry and, as a historian, I hope to remedy this knowledge gap. For, it is the responsibility of the historian to review the historical underpinnings of

The prevalence of injury in volleyball is considered lower than in other team sports, such as basketball, handball, or soccer. 1 , 2 These differences are thought to be the consequence of the noncontact nature of volleyball. 3 , 4 However, volleyball injuries accounted for 5.3% of all sports

The volleyball attack is the action winning most of the points during a game, and attack effectiveness (AE) is consequently thought to be one of the most important predictors of victory. 1 , 2 It can be performed in a number of ways, most commonly in the form of a “spike.” This is a unique

Volleyball players and nonplayers were compared for speed and accuracy of performance in a task involving detecting the presence of a volleyball in a rapidly presented slide of a volleyball situation. The volleyball situations depicted both game action and nongame events, for example, timeouts and warm-ups. Players and nonplayers did not differ in accuracy of response, but players were much faster in responding for both game and nongame slides. Further experiments showed that volleyball players' speed of response in ball detection was not a function of a simple athlete-nonathlete difference, nor of volleyball players' being fast at visual search in a nonvolleyball environment. The perceptual skill shown by volleyball players in this series of experiments is best described as a rapid visual search specific to the ball as target.

Countermovement jumps loaded with a weighted vest are often used for the training of lower body power to improve jump performance. However, it is currently unknown how this added load affects the lower extremity kinematics and kinetics, in particular whether this results in an increased injury risk. Therefore, the purpose of this investigation was to determine how lower extremity kinematics and kinetics during landing are affected by loaded jumps as demonstrated in a volleyball block jump landing. Ten elite male volleyball players performed block jump landings in an unloaded and loaded (9.89 kg) condition. Kinematic and kinetic landing data from the three highest jumps were collected and assessed. Paired samples t test was used to establish whether load condition had a significant effect on lower extremity kinematics and kinetics. Hip flexion was significantly greater in the unloaded condition compared with the loaded condition (p = .004). There was no significant difference in any other kinematic or kinetic variables measures between the unloaded and loaded conditions. These results suggest that landing from loaded volleyball block jumps does not increase injury risk compared with unloaded jumps in elite male volleyball players.

The sport of volleyball is characterized by multiple high-intensity bouts of repetitive explosive efforts, each usually 5–20 seconds in duration ( Sheppard, Gabbett, & Stanganelli, 2009 ). In addition, play requires the manipulation of a fast-moving, airborne ball which can only be rebounded off
