The purpose of this work was to present a model which shows the efficiency of the actions in the game of soccer, based on observations of 7 final tournament matches during the European Championships in 2008. The successful teams were analyzed from the quarterfinals to the final match. Activity, effectiveness and reliability, during both offensive and defensive actions, were subject to this examination.The material consisted of the audio-visual records gathered from 7 matches which had been played in the final tournament in the 2008 European Championships. The gathered data was put on the special observation sheet in accordance with the Panfil's design.It has been ascertained that the most effective actions are those of possessing the ball and the actions of gaining the field, while the rate of scoring goals is similar to that which had been observed during finals in other top soccer tournaments. Additionally, in the defensive actions the best players manifest higher reliability in co-operation than in individual actions.In the top-level competitions, group/team actions prevailed over individual ones. The examined players manifested nearly the same efficiency in scoring like those who took part in the finals of the World and continental championships. The players regarded as champions made use of various individual actions against their opponents with a ball, depending on the implemented game tasks.The models which illustrate the efficiency of actions in soccer, at the top-level competition should be used for creating ideal models which will design the game of players of lower sport competence.

Introduction. Results of laboratory tests could be treated as a valuable source of information about players’ physical fitness. Aim of Study. The purpose of this study was to identify laboratory physical fitness tests that could be useful for predicting competences of 17-year-old soccer players. Material and Methods. Selected components of players’ physical fitness were assessed and the effectiveness of game performance was evaluated in a group of eighteen young soccer players. The following parameters were measured: anthropometric measurements, anaerobic and aerobic capacity, locomotion speed, explosive strength of the lower limbs, reaction time, and balance. Results. The results achieved in laboratory and exercise tests were converted into ranks. An assessment of players’ effectiveness in one-on-one games was made using special oneon-one test methodology, and a list of ranked game performances was prepared. On the basis of observations made by three independent experts, the participants were classified according to their “usefulness” for the game using the Game Performance Assessment Instrument (GPAI). The ranking assessment of the effectiveness of one-on-one games and of a classified game was correlated with the results of laboratory tests. It was found that players with the highest scores in locomotion speed tests and in the explosive leg power test were also highly assessed by the experts with regard to the efficiency of their performance in one-on-one games as well as, to a slightly lesser degree, in the classified game. There was no significant relationship between the expert assessment of “usefulness” for the game and other tests. Conclusions. On the basis of strength-speed test results we may satisfactorily predict young soccer players’ efficiency of game performance.

Background: The purpose of the study was to develop a model mapping the efficiency of actions of futsal goalkeepers based on observation of their game in eight matches of the cup finals the World and European Championships in 2012. Material/Methods: Data about the game were recorded on originally developed observation sheets. Activity, effectiveness and reliability of particular offensive and defensive actions aiming at achieving objectives of the game were investigated. Results: It was found that in attack futsal goalkeepers mostly perform actions whose aim is to gain the playfield with the ball by passing it with a foot from the ground and to keep the ball by receiving it from partner. In turn, in defence, they mostly prevent losing goals by pushing the ball. Conclusions: The created models of players’ performance should be used to create models shaping the game of players of a lower level of proficiency in order to improve the efficiency of their games as well as to develop individual programs of training for futsal goalkeepers.

Background: The aim of this study was to identify and compare the efficiency of action-effective football players in one against one situations (1×1). Material/Methods: The game of winning teams' players was observed in four matches and two semi-final meetings of the European Championships tournament in 2004 and 2008. Visual recording was monitored using a freeze-frame function and data about the players' game were recorded on observation sheet by Szwarc. The activity, effectiveness and reliability of individual offensive and defensive actions were estimated. Results: It was found that on average players of the best teams in Europe participated in 216 1×1 battles (from 184 to 273) in one game, with an average reliability of 52%. Conclusions: Furthermore, it was proved that players-champions engaged equally often and with the same effectiveness in both individual defensive measures and offensive actions.

The purpose of this paper was to present cognitive models illustrating efficiency of the goalkeeper's actions in soccer based on observation of play in selected matches of the Euro 2008 finals.The observation method was used in the study. The play of both goalkeepers was analysed in 7 soccer matches in a cup phase of the European Championships which took place in Portugal in 2008. The data was recorded on the authors' observation forms. Activity, effectiveness and reliability during both offensive and defensive actions were subject to this examination.It was revealed that most actions of the goalkeeper are aimed at taking control of the field of play or keeping possession of the ball; creating goal scoring opportunity represents only a small percentage of offensive actions. Defensive actions are generally performed individually and the highest reliability is reported while catching the ball.Efficiency models of goalkeepers' actions should be used to create models of play for players representing a lower level of sports competence in order to improve the effectiveness of their game play. One should continue further study to improve a research tool so as to evaluate other, important from the point of view of the game's objectives, actions definitely dependent on team mates' behavior.

Background: ‪The aim of this study is to examine and compare the distance covered with high-intensity running and to determine differences in maximum velocities achieved in a match by 15–19-year-old elite Polish soccer players depending on their age and playing positions. Material and methods: ‪The current study monitored and analyzed 528 matches of youth soccer players of six tactical positions (12 goalkeepers, 24 fullbacks, 24 central backs, 24 wide midfielders, 36 central midfielders and 12 forwards) from four age categories (U-15, U-16, U-17 and U-19) from three top Polish soccer academies, using a MinimaxX device. Results: ‪It was found that in every age category, central midfielders covered the longest total distance, while wide midfielders covered the greatest distance with high-intensity running. Maximum velocities of players of U-17 and U-19 were significantly higher than players of U-15 and U-16. The highest maximum velocities were achieved by the wide midfielders and forwards of U-19 players. Conclusions: ‪The selection of players for certain positions in the game must take into account the players’ ability to perform high intensity running, sprints and ability to repeat very high intensity running.

In the article the occurrence ofseveral natural thresholds in Vistula River valley was discussed. These forms are stabilizing river channel regime and impeding shipping at the same time. The example of application of ground penetrating radar (GPR) for detecting and identifying the erosion zones in the bottom of the river valley was presented. The investigations were carried out along the chosen section of Vistula River in the vicinity of Gdansk Bridge (Most Gdański) in Warsaw. The survey was conductedfrom a motorboat with the MALA GroundExplorer (GX) georadar system installed with 160 MHz screen antenna. The prospection down to 7.5 m below the water surface was obtained. The applied methodology allowed to obtain radar echograms indicating the following anomalies: from the river bottom, from cohesive soil (includingNeogene clays) andfrom thresholds (noticeably elevatedforms in the bottom). In identifying and interpreting georadar anomalies, archival boreholes data were used.
