THE IMPORTANCE OF CORNERS IN THE TACTICAL PREPARATION OF PROFESSIONAL FOOTBALLERS

Corners are a segment of the game from which goals are not often scored, but they may be a decisive factor in the outcome of the match between the two teams. The aim of this research is to determine the characteristics of performing a corner kick and to examine whether there are differences between different competitions of professional football players. The sample of respondents represents the matches of the International Champions Cup in the 2018 season and the matches of the Spanish league (La Liga) in the 2017/2018 season. A total of 23 matches (13 matches of the International Champions Cup and 10 matches of the Spanish league) were analyzed. To describe the tactics of corner kicks, variables were observed that indicate the way the kicks are performed from the corner. The methodology of observing several teams, monitoring all matches and monitoring both teams in each match with the analysis of given variables was used. Corner kicks that had more than three passes, which means starting a new, organized attack, were excluded from the analysis. A total of 209 of the 253 corners were included. The results show that there is no statistically significant difference in most of the observed parameters, but in the type of defense that the teams apply, play and lateral performance, there are statistically significant differences. Zone defense (.012) is used more by teams that competed in the International Champions Cup and combined (.036) by teams in the Spanish league. There are also differences in the playoffs (.047) in favor of the International Champions Cup. Corners from the same side (.031) were used more in the International Champions Cup than in the Spanish league. These results show that the teams do not differ much in the way they set up in the defensive phase and the attack phase, but that there are certain common criteria. Article visualizations

DIFFERENCES OF MOTOR AND FUNCTIONAL ABILITIES IN FOOTBALL AND HANDBALL PLAYERS AGED THIRTEEN TO FIFTENN YEARS

The research was conducted on fifty subjects aged between thirtheen and fifteen years in Niksic, in order to determine whether there were statistically significant differences in the level of motor and functional abilities in football and handball players, and to determine the difference in quantitative and qualitative changes of motor and functional abilities in football and handball players aged thirteen to fifteen years. The study applied a system of eleven variables that hypothetically cover the space of motor and functional abilities. For all applied variables in this study, central and despersion parameters are calculated and measure of asymmetry and exterior, and normality of distribution was checked with Kolmogrov-Smirnov’s test. T-test was applied in order to check if there were applied variables of statistic quantitativ differences. For determination of difference between applied variables discriminative parametric procedure was used. To determine differences between group of variables and group of respondents discriminative analysis ws applied. The results showed that there were statistically significent differences between football and handball players aged thirteen to fifteen year
