Abstract Background: The aim of this study was to compare the postural control of the Poland national women’s volleyball team players with a control group of non-training young women. It was hypothesized that volleyball players use a specific balance control strategy due to the high motor requirements of their team sport. Methods: Static postural sway variables were measured in 31 athletes and 31 non-training women. Participants were standing on a force plate with eyes open, and their center of pressure signals were recorded for the 20s with the sampling rate of 20 Hz in the medial-lateral (ML) and anterior-posterior (AP) planes. Results: In both AP and ML planes, athletes had lower range and higher fractal dimension of the COP. They had also higher peak frequency than control group in the ML plane only. The remaining COP indices including variability, mean velocity and mean frequency did not display any intergroup differences. Conclusion: It can be assumed that due to the high motor requirements of their sport discipline Polish female volleyball players have developed a unique posture control. On the court they have to distribute their sensory resources optimally between balance control and actions resulting from the specifics of the volleyball game. There are no clearly defined criteria for optimal postural strategies for elite athletes, but they rather vary depending on a given sport. The results of our research confirm this claim. Trial registration: The tests were previously approved by the Bioethical Commission of the Chamber of Physicians in Opole. (Resolution No. 151/13.12.2007). This study adheres to the CONSORT guidelines. Keywords: Volleyball, Postural control, Posturography, Center of Pressure
Background The ability to maintain a stable standing position is regarded as the fundamental objective in most motor activities. Human postural stability depends on the availability of intact sensory information including proprioceptive, vestibular, and visual afferent signals, central integration of those signals, and motor execution which must take into account various internal and environmental constraints. Although the textbook definition of upright stance maintenance seems to unfold this * Correspondence: [email protected] 1 Faculty of Physical Education and Physiotherapy, Opole University of Technology, ul.

complex process, researchers still face numerous problems related to the understanding of the actual function of modalities responsible for postural control, their dependence on age and pathologies, and performance in extreme situations, for example, experienced by athletes. The study of postural control in athletes could provide some insight into the development of specific postural strategies required by a particu
