The article concerns the processes of change in the two clubs competing in football and volleyball, which followed the period of dynamic growth. In the case of the football club investigation period covers the years 2004-2012, and the club volleyball are the years of 1999-2012. The development of these organizations expressed not only through increased sports performance, but also through formal and legal changes, involving the evolution from associations to join-stock companies. These phenomena affect the development of the organizational structure and the appearance of new jobs. The purpose of this article is to present the changes in sports clubs in the managing structure and tasks of the key players on the example of men's soccer and women's volleyball. The methods have been applied are the interview and document analysis. The respondents were longterm employees of clubs, and examined documents were job descriptions of employees. The results show the appearance of many new jobs and expanding existing tasks. Additionally strong impact on the surveyed organizations of competitions in which the team participated and organizational culture of the owners, was observed. The study concludes that all clubs seeking to develop high-quality sports products should consciously optimize their structure and shape the attitudes of employees readiness to change and look for employees with the highest competence, effectively performing the organizational and management tasks. This situation is consistent with trends in sports organizations in the world, which creates favorable conditions for the development of professional sport in Poland.
Background. The article concerns high level beach volleyball players’ actions and in particular the issues of evaluation. The main object of the analysis is the setting which seems to be an action that can increase the efficiency of the attack. It was assumed that setting skills are very important part of synergistic potential of players. Material and methods. In process of evaluation an original method of observation and a modern approach based on the evaluation criteria of players’ skills proposed by Panfil was used. The study was based on three criteria: correctness, diversity and flexibility. Research materials were the recordings of 12 men’s beach volleyball matches played during the top international tournaments of the 2011 and 2012 FIVB Beach Volleyball SWATCH World Tour. Results. We recorded the number of actions, average level of correctness, diversity and flexibility for each of the selected 20 players. Flexibility was determined by two indexes: dependent flexibility and independent flexibility. Conclusions. It is essential to provide important aspects of the game characteristics and prepare hints for the training process designed for top beach volleyball teams, based on the solutions used by the best teams in the world. Additionally, the paper discussed and verified new tools that expand the general criteria of players’ skills evaluation proposed by Panfil specifically to beach volleyball.

Purpose. The aim of this study was to analyze and evaluate beach volleyball defensive strategies in terms of how often various tactics were employed, their effectiveness, reliability, and overall efficiency based on a sample of elite female volleyball players. Methods. A sample of 746 defensive actions performed by various teams that competed in the 2008 Summer Olympic Games (Beijing, China), the 2009 World Championships (Stavanger, Norway), and the 2009 and 2010 Swatch FIVB Beach Volleyball World Tour (Stare Jabłonki, Poland; Seoul, South Korea) were analyzed in terms of what defensive systems were employed and their outcomes. Results. Fourteen different defensive systems were used by the teams during defensive play. Out of the fourteen systems, four accounted for almost 75% of all defensive action. The most commonly used defense strategies were selected for more detailed analysis in terms of their activity, effectiveness, and reliability. Conclusions. One defensive system in particular was found to be the most prominent in terms of being the most commonly used as well as efficient among all of the observed systems; high-level teams should place additional focus on mastering this system. Nevertheless, effective team strategy should also include less commonly used systems as a way to take an opponent by surprise by the use of non-standard strategy.
The study assesses the effects of a six-week plyometric training program (PT) on muscle stiffness in the dominant and non-dominant leg in male collegiate volleyball players. The study group comprised 16 volleyball players who had played collegiate volleyball for at least four years. For six consecutive weeks, twice a week, the players undertook a plyometric program of 60-min training sessions, each preceded with a specialist warm-up. The analysis of the anterior muscles of the right and the left lower leg revealed a significant increase in stiffness in the muscles of the right leg and the left leg. No significant differences were found between the anterior muscles of the left lower leg and the right lower leg in particular weeks of the training program. The analysis of the posterior lower leg muscles revealed no significant differences, either in the consecutive weekly training microcycles or between the left leg and the right leg. The measurement of muscle tone and biomechanical properties of muscles can be used as a fast and direct assessment of plyometric training-related muscle fatigue. A similar level of muscle stiffness in both lower legs (symmetry) is a reflection of the appropriate selection of plyometric training loads.
