Differences in the Parameters of Motor Skills Between Individual Positions in the Game in Young Football Players : Master's Thesis

Ovo istraživanje je provedeno na uzorku od ukupno 176 mladih nogometaša u dobi od 9 do 11 godina iz 7 različitih klubova, s ciljem da ustanovimo postoje li razlike u morfološkim i motoričkim sposobnostima između tri različite pozicije (braniči, vezni igrači i napadači). Uzorak varijabli se sastojao od dvije antropometrijske mjere i 6 motoričkih testova. Za analizu podataka korištene su mjere centralne tendencije: aritmetička sredina, standardna devijacija, minimalni i maksimalni rezultat, a za razliku značajnosti je korištena analiza varijance (ANOVA), dok je post-hoc Scheffe test korišten za utvrđivanja između kojih konkretno pozicija postoje značajne razlike. Nalazi su pokazali da u kategoriji U9 i U10 postoji značajna razlika veznjaka naspram braniča i napadača u testovima agilnosti, te postoji razlika između braniča i veznjaka u kategoriji U11 u visini igrača. Ovakvi nalazi su potvrdili našu pretpostavku da će postojati razlika između pojedinih pozicija u igri.This research was conducted on a sample of a total of 176 young soccer players aged 9 to 11 from 7 different clubs, with the aim of establishing are thereany differences between three different positions (defenders, midfielders and forwards) in morphological and motor skills. The sample of variables consisted of two anthropometric measurements and 6 motor tests. Measures of central tendency are used for data analysis: arithmetic mean, standard deviation, minimum and maximum and analysis of variance (ANOVA) is used for significance difference, while the post-hoc Scheffe test is used to determine between which specific positions there are significant differences. The findings showed that in the U9 and U10 categories significant differencesare between midfielders against defenders and forwards in agility tests, and there is a difference between defenders and midfielders in the U11 category in terms of player height. These findings confirmed our hypothesis that there will be a difference between certain positions in the game
