OBJECTIVE Abnormal imaging in the patellar tendon reveals pathology that is often associated with knee pain. Anthropometric measures of body size and mass, such as height, weight and waist-to-hip ratio (WHR), have been individually associated with abnormal imaging. The aim of this study was to investigate the anthropometric factors that have the strongest relationship with abnormal imaging in v...

This study evaluated force and velocity parameters of vertical jump performance in countermovement jump (CMJ) and squat jump (SJ) and compared results for sprint runners and volleyball players. Twenty-four male athletes (12 regional/national-level sprint runners and 12 national-level volleyball players) performed CMJ and SJ on a force platform. The following variables were analyzed: jump perfor...

BACKGROUND Beach volleyball is an intensive sport with high impact on the lumbar spine. Low back pain (LBP) is frequent among elite players. Increased prevalence of pathological changes on magnetic resonance imaging (MRI) in the lumbar spine of elite athletes has been reported. HYPOTHESIS There is an increased prevalence of disc degeneration and spondylolysis in the MRI of the lumbar spine of...

The purpose of this study was to examine beach volleyball players' experience regarding shoulder injury and how it affects their return to play. To achieve the research aims a qualitative design with semi-structured interviews had been conducted, five elite beach volleyball players, four men and one woman aged 27-42 participated in the study. All participants had suffered a severe shoulder inju...

The main purpose of the study was to examine whether M Capacity, as it is defined in Pascual-Leone’s Theory of Constructive Operators as the maximum number of schemes which can be simultaneously activated by attentional resources, is predictive of motor learning – in this case, of the acquisition and development of the “third touch” in volleyball. This hypothesis, supported by some preliminary ...

The primary aim of this research was to study visual spatial attention and its impact on the accuracy diagonal spike in volleyball. A total 20 volleyball players Baghdad participated study. sample homogeneous terms height, weight age players. tests used present were: 1) Visual Spatial Attention Test. 2) Volleyball Spike Based findings study, researcher concluded that has a significant

Regarding the effects of the kinematics of the movement on athletic performance and the Importance of promoting athlete’s performance on the sport fields, there is limited knowledge about the mechanism of the effect of different variables of volleyball spike. Therefore, the aim of this study was the prediction of jump performance in elite female volleyball players with selected kinematic variab...

[Purpose] The purpose of this study was to investigate differences in jumping ability and lower limb balance ability elicited by plyometric training and vibration exercise, of volleyball players with and without ankle injuries, which frequently occur among Korean professional volleyball players. [Subjects and Methods] Twenty-eight volleyball players were divided into the following groups: plyom...

Newton, R.U., R.A. Rogers, J.S. Volek, K. Häkkinen, and W.J. Kraemer. Four weeks of optimal load ballistic resistance training at the end of season attenuates declining jump performance of women volleyball players. J. Strength Cond. Res. 20(4):955–961. 2006.—Anecdotal and research evidence is that vertical jump performance declines over the competitive volleyball season. The purpose of this stu...

The purpose of this study was to investigate changes in reaction time of elite volleyball players during a game. Fourteen volleyball players participated in the study. Reaction time was measured using the Optojump system. In addition, blood lactate concentration was assessed to monitor physiological load during the game. All measurements were performed during a pre-game test and during sets 1, ...
