Article excerpt

Introduction

Some authors characterize the structure of game performance in sports games as a unity of execution and result of certain activity or as a particular complex sequence of activities, that are measured are or evaluated on the basis of certain socially determined norms or as an internal structure of factors (elements, components) which mutually influence each other and optimally manifest themselves and they are necessary to achieve specific game performance. Game performance is realised in specific movement activities, where the content involves solution of the tasks, which are defined by the rules of given sport where the athlete tries to reach maximum to apply predispositions to achieve his performance. (Slovík, 1989; Morton, Williams et al. 1994; Dovalil et al., 2002; Court, 2002; Mohr, Krustrup, Bangsbo, 2003; Peráček, Hrnčiarik. 2010).

Evaluation of game performance is used to assess the effectiveness of strategies and tactics of the game of your own team and your opponent's team, to find out the development tendencies of the game etc. It is a valuable source of information to evaluate the effectiveness of the training process and further corrections. Evaluation of the game performance belongs to basic questions of theoretical and practical character. (Ejem, 1970; Hohmann and Brack, 1983; Dobrý and Semiginovsky, 1988; Reilly, 1994). Diagnostic activity is aimed at evaluation of the player during the match and in the training process. It leads to getting better knowledge of the current form of the player and possibility to compare information which was already gained. According to this knowledge the players are ranked in particular group, category (Lames, 1994; 1996,). To understand the game performance of the most successful teams means to understand the game performance of an individual player in his particular player's functions. Modern way of managing the preparation is not possible without applying continuous amount of different information. This applies to any function of the player in a team, including goalkeeper. (Brueggemann, 2008).

Material & methods

The aim of this research was to analyse selected indicators of an individual game performance of the goalkeepers at the European Championship 17 year old elite soccer players. (spread the knowledge on selected characteristics of an individual game performance of the goalkeeper in elite soccer).

Research hypothesis

H1: We presuppose that the frequency of offensive game activities in monitored goalkeepers will be statistically significant higher than defensive game activities in all matches.

H2: We presuppose that the most of the goalkeeper's game activities are executed at the end of the first and second half of a match.

H3: We presuppose that in elimination round of the tournament the frequency of offensive and defensive game activities of a goalkeeper will be statistically significant higher than in basic round of a tournament.

H4: We presuppose that in elimination round of the tournament the overall successfulness of the goalkeepers will be higher than in basic round.

Research design

The object of the research was monitoring the goalkeepers, members of the national teams, taking part in the European Championship 2013 to 17 years, in Slovakia. In the final matches which we had selected we monitored and recorded some single offensive and defensive game activities.

To evaluate different game activities during the match according to successfulness and unsuccessfulness of the goalkeeper, KOSTOLANSKY's (2006) scale of rating was used. It has an optimal number of levels (5) plus verbal description, expressing the different levels of certain specific game activities of the goalkeeper.

We have evaluated 10 game situations of the goalkeepers at the European Championship 17 year old soccer players. Out of the total, three of them were offensive game activities (OGA) and seven, defensive game activities (DGA). …
