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.

Purpose: This study aimed to investigate the impact of a 6-week upper-body plyometric-training (PT) program with varying volumes on the immunoendocrine, physiological parameters, and physical performance adaptations in male volleyball players.
Methods: Twenty-four trained college players were randomly allocated into 3 groups with 8 participants. Each group performed 5 exercises at maximal effort with differences in volume: low (3 sets of 7 repetitions), moderate (3 sets of 10 repetitions), and high (3 sets of 13 repetitions).

The assessment of the various skills of athletes is carried out in terms of their ability to perform sport-specific tasks. The cognitive abilities of the players have significance for their effectiveness. In volleyball, a player's ability to react quickly appears to be crucial in responding to an opponent's dynamic play.

Background: The aim of this study was to examine the effects of long-term (10 months) volleyball training on biochemical responses in adolescent female athletes since the cumulative effects of chronic training on this population are not yet clear.
Methods: Twenty-one adolescent female volleyball players competing at the national level served as the participants. All athletes carried out volleyball training, which consisted of ball handling, specialized drills, and practical game-style exercises, including physical training in the school gymnasium.

The objective of the present study was to examine the impact of different plyometric training (PT) surfaces on the adaptive changes of jumping ability, sprinting speed, change of direction ability and strength performance in volleyball players. Forty male players participated in the study and were divided into four equal groups performing PT in aquatic (APT), sand (SPT), and land (LPT) surfaces, or an active control group (CON). All training groups indicated small to large significant (p = 0.

Objectives: This study aimed to investigate the effects of external (EXT) versus internal (INT) focus of attention on acquiring and transferring simple and complex motor skills in novice female volleyball players.
Methods: Fifty-seven participants were assigned to one of the three groups: The external focus (EXT), the internal focus (INT), and the control group (CON). Over a 6-week intervention, participants practiced a simple skill (volleyball passing) and a complex skill (overhead tennis serve).
