The aim of the diploma work was to analyse and measure the motor skills of football players (N-40) aged 13 years and less (U-13). The sample consisted 20 members of ŽNK Krim and 20 of ŽNK Maribor.
For testing we used 5 different tests: direction changing fast run, distance jump from the spot, combined half circle, direction changing ball leading and Yo-Yo IR1. For easier comparison of data we organized the players by their position: 14 mid-fielders (35%); 8 forwards (20%); 14 defence line players (35%) and 4 goal keepers (10%). The game system played by the club is 1:2:1:2 and the goal keeper (6+1). We compared the players according to the club and according to the game positions (lines).
Data was statistically processed in IBM SPSS 24 (SPSS Inc., Chicago, USA). Hypothesis about average values of variables were verified with Shapiro-Wilk's test. The homogeneity of variables was tested with Leven test. We used Mann-Whitney test and Kruskal-Wallis test to analyse all the results.
The results showed that all 5 hypotheses were confirmed, as there were no statistical significant differences between the playing positions and among the players from different clubs in any performed test. No statistically significant differences were found at a risk level of 5%.
In the end, we made two comparisons. We compared football players U-13 (ŽNK Maribor and ŽNK Krim) with soccer players from the women's national team of Slovenia U-19 and ŽNK Slovenj Gradec. We used average values from four tests. In the second comparison, football players U-13 (ŽNK Maribor and ŽNK Krim) were compared with soccer players of the U-14 selection from NŠ NK Krško. We also used the average values of the four tests.
