Temeljni namen magistrskega dela je bil izdelava norm za vrednotenje telesne in gibalne pripravljenosti slovenskih odbojkarjev in odbojkaric, starih 14 in 15 let. Cilj magistrskega dela je bil ugotoviti, ali prihaja pri izbranih meritvah telesnih razsežnosti in gibalnih sposobnosti do razlik med igralci, ki so bili kasneje iz regijskih reprezentanc izbrani v državne reprezentance in tistimi, ki niso bili. V vzorec je bilo vključenih 356 odbojkarjev in 363 odbojkaric, ki so se v letih od 2015 do vključno 2019 udeležili Turnirja regijskih reprezentanc. Vzorec spremenljivk so predstavljale 3 merske naloge za oceno telesnih razsežnosti in 10 merskih nalog za oceno gibalnih sposobnosti. Za urejanje in obdelavo podatkov smo uporabili Excel in IBM SPSS Statistics. Norme za vrednotenje rezultatov meritev smo izrazili s centili, za ugotavljanje razlik glede na kasnejše članstvo v državni reprezentanci pa smo uporabili t-test za neodvisne vzorce. Izdelane norme lahko uporabimo kot model za vrednotenje posameznikovega potenciala v tej starostni kategoriji. Trenerju in igralcu omogočajo vpogled v to, kje v Sloveniji se posameznik nahaja glede na najboljše 14- oziroma 15-letnike. V povprečnih vrednostih dosegajo igralci in igralke, ki so bili iz regijskih reprezentanc kasneje izbrani v državne reprezentance pri večini merskih nalog boljše rezultate kot igralci, ki v državne reprezentance niso bili izbrani. Rezultati so pokazali, da pri 14-letnih dečkih med skupinama regijskih in državnih reprezentantov ne prihaja do statistično značilnih razlik, medtem ko smo pri 15-letnikih ugotovili statistično značilne razlike pri dveh testih: doskočna višina z zaletom in doskočna višina v bloku. Pri 14-letnih deklicah prihaja med skupinama do statistično značilnih razlik pri sedmih merskih testih (telesna višina, dosežna višina, doskočna višina z zaletom, doskočna višina v bloku, predklon na klopci, met 2 kg težke medicinke soročno sede in skok iz polčepa), pri 15-letnicah pa pri šestih (telesna višina, dosežna višina, doskočna višina z zaletom, doskočna višina v bloku, skok iz polčepa in FitLight z neznano kombinacijo). Povsod, kjer je med skupinama prihajalo do statistično značilnih razlik, so državni reprezentanti in reprezentantke dosegali višje oziroma boljše rezultate kot regijski reprezentanti in reprezentantke (z izjemo rezultatov testa skoka iz polčepa pri 15-letnicah). The main purpose of the master's thesis was to create norms for the evaluation of physical and motor conditions of Slovenian volleyball players aged 14 and 15 years. The goal was to find out whether there are differences in measurements of body dimensions and motor skills among players who were later selected from regional to the national teams and those who were not. The sample included a total of 356 male and 363 female volleyball players who participated in the Tournament of regional teams in the years from 2015 to 2019. The sample of variables represented three measurements for the assessment of body dimensions and ten measurement tasks for the assessment of motor skills. The data was organized and analyzed using Excel and IBM SPSS Statistics. Norms for evaluating the results were expressed with percentiles, and t-test for independent samples was used to identify differences with respect to later membership in the national team. Norms can be used as a model for the evaluation of the individual’s potential in specific age category. Norms offer a comparison between an individual and the best 14- and 15-year-olds in Slovenia. On average, the players who were later selected from the regional to the national teams achieved better results in most measurement tasks than the players who were not. The results showed that there were no statistically significant differences between the groups of regional and national teams in 14-year-old male players, while the differences were found in two tests among 15-year-olds: spike reach and block reach. In 14-year-old female players there were statistically significant differences between the groups in seven measurement tests: body height, standing reach, spike reach, block reach, bend on the bench, throw of a 2 kg heavy medicine ball with both hands in a seated position and squat jump. In 15-year-old female players there were statistically significant differences between groups in six measurement tests: body height, standing reach, spike reach, block reach, squat jump and FitLight with an unknown combination. Wherever there were statistically significant differences between the groups, the members of a national teams achieved better results than members of a regional teams (except for a 15-year-old female players when testing a squat jump).

V odbojki predstavljajo telesne značilnosti in gibalne sposobnosti osnovo za kvalitetnega odbojkarja. Telesne značilnosti, kot so velika telesna in dosežna višina ter razvite gibalne sposobnosti kot so moč, hitrost in koordinacija so v odbojkarski igri zelo pomembne. Čim boljši razvoj gibalnih sposobnosti je cilj vsakega igralca in trenerja. V diplomskem delu smo primerjali nekatere generacije mladih odbojkarjev regijskih reprezentanc v kategoriji dečkov v izbranih morfoloških lastnostih in motoričnih sposobnostih v odbojki. Primerjali smo rezultate testov odbojkarjev, ki so bili izvedeni pred nastopom ekip na tekmah regijskih reprezentanc. Meritve so zajemale morfološke značilnosti in motorične sposobnosti. Posvetili smo se le testom, ki jih je izvajala večina generacij odbojkarjev regijskih reprezentanc. Vzorec merjencev zajema 554 odbojkarjev starih med 14 in 15 let, ki so sodelovali na tekmovanju regijskih reprezentanc od leta 2004 do leta 2017. S pomočjo programa Excel in statističnega programa IBM SPSS Statistics smo podatke odbojkarjev uredili in analizirali. Med seboj smo primerjali rezultate med izbranimi generacijami in regijami. Pri morfoloških značilnostih merjenih odbojkarjev smo ugotovili trende izboljševanja rezultatov skozi izbrane generacije, s primerjavo testov motoričnih sposobnosti izbranih generacij odbojkarjev pa smo opazili trende izboljševanja rezultatov pri testih, na rezultat katerih v največji meri vpliva telesna višina in eksplozivna moč nog. Največji napredek pri rezultatih morfoloških značilnosti odbojkarjev je bil opažen v Ljubljani z okolico. Koroška regija je pri testih motoričnih sposobnosti v izbranih generacijah največkrat dosegla najvišji rezultat, primorska regija pa je prikazala trend nazadovanja pri rezultatih motoričnih testov v primerjavi z ostalimi regijami. In volleyball, physical characteristics and motor skills represent a foundation for a good volleyball player. Morphological properties like height and reach and developed motor skills like strength, speed and coordination are vital in volleyball. Development of motor skills is the goal of every player as well as the trainer. We compared some generations of young volleyball players who competed in the regional tournament in chosen morphological properties and motor skills in volleyball. We compared the results of tests that were carried out before the start of regional tournament matches. Measurments contained morphological properties and motor skills. We only analysed and compared the reasults whitch were measured in most of the chosen generations of volleyball players in the regional tournaments. The sample includes 554 volleyball players aged between 14 and 15, who participated in the regional tournaments from year 2004 to 2017. The data was organized and analysed using Excel and IBM SPSS Statistics. We compared results of the chosen generations and regions. In the morphological characteristics of measured volleyball players, we determined trends of improving results through selected generations. By comparing motor skills tests of selected volleyball generations, we determined trends of improving in tests of which the results are mostly affected by body height and explosive power. The greatest progress in results of the morphological characteristics of volleyball players was observed in Ljubljana and its surroundings. Koroška region achieved most of the highest results in the tests of motor skills in selected generations, while primorska region showed a downward trend in results of motor tests compared to other regions.
