Obzirom na specifičnosti odbojke logičan je
značajan utjecaj pojedinih morfoloških karakteristika na
uspjeh u igri. Morfološkom antropometrijom može se
prikupiti dio informacija za primarnu selekciji kandidata
za odbojku, ali i informacije koje se mogu koristiti u
sekundarnoj selekciji - specijalizaciji tj. odreðivanju
specifičnih igračkih uloga sa specifičnim igraèkim
zadacima. Zadaci su karakteristični za svaku igraèku
poziciju pa je i važnost pojedinih morfoloških mjera
različita. Cilj istraživanja je da se kroz analizu
antropometrijskih karakteristika provjeri znaèajnost
razlika s obzirom na specifične igračke uloge. Istraživanje
je izvršeno na uzorku 60 prvoligaška odbojkaša (n=60)
èlanova prve hrvatske i slovenske odbojkaške lige u
natjecateljskoj sezoni 2007/2008. Obzirom na cilj
istraživanja igrači su podijeljeni u skupine sukladno
svojoj igraèkoj ulozi: dizaèi (n=9), centralni igrači (n=13),
primaèi – napadači (n=16), korektori (n=16) i libero
(n=6). Uzorak varijabli èini 27 antropometrijskih mjera , a
mjerenje je izvršeno prema preporukama IBP-a. Na
manifesnom skupu antropometrijskih varijabli
primijenjena je metoda glavnih komponenata kako bi se
utvrdila struktura latentnog prostora. Neortogonalnom
rotacijom prema kriteriju varimax normalized
transformiran je inicijalni koordinatni sustav da bi se
dobila jednostavna struktura faktora. Potom su izračunati
faktorski skorovi ispitanika te aritmetičke sredine skupina
u standardiziranim vrijednostima. Znaèajnost razlika
izmeðu skupina odbojkaša razlièitih igraèkih pozicija
testirana je ANOVOM (Tukey HSD post – hoc testom).
Dobiveni rezultati potvrðuju hipotezu o postojanju
znaèajnih razlika u prostoru antropometrijskih
karakteristika izmeðu skupina odbojkaša različitih
igračkih uloga koja je potvrðena u nizu prethodnih
istraživanja. Faktor LDS identificiran je kao jedini na
kojem se igraèke skupine značajno razlikuju. Skupina
centralnih igraèa postigla je značajno više rezultate od
svih ostalih osim skupine korektora. Dobivene
informacije mogu poslužiti kao normativne vrijednosti te
kao podrška u usmjeravanju igrača prema odreðenoj
igračkoj ulozi u cilju optimiziranja njihove situacijske učinkovitosti te postizanju optimalnih takmičarskih rezultata u sportskoj karijeri.Regard to specificity of volleyball game
considerable effect of certain morphological
characteristics on the success of the game is logical. Using
morphological anthropometry it is possible to collect
informations for primary selection of candidates for
volleyball, but also informations that could be used in the
secondary selection - so called specialization.
Specialization determinates specific playing roles with
specific assignments for each player. Assignments are
typical for each playing role so the importances of certain
morphological measures are different. The aim of this
study was to examine the positional differences in the area
of anthropometric characteristics of Croatian and
Slovenian premier league volleyball players. The research
was conducted on a 60 senior volleyball players all
members of Croatian and Slovenian premier league.
Players were categorized as setters (n=9), receivers –
attackers (n=16), diagonal players – correctors (n=16),
central players (n = 13) and liberos (n=6). The sample of
variables consisted of 27 anthropometric measures all
taken following the guidance of the IBP. The factorization
of the variables was conducted using the factor analysis.
Using Varimax normalized rotation initial coordinative
system were transformed to obtain simple structure of the
factors. According the Guttmann Kaiser criterion four
significant factors were extracted. Factor scores are
calculated for each respondent and each categorized
group on each extracted factor. A one-way analysis of
variance (ANOVA) with Tukey HSD post-hoc test was
used to determine possible significant differences among
positions on four extracted factors. The level of
significance was set at 0.05. Obtained results confirm the
hypothesis of the existence of significant differences in
the area of anthropometric characteristics considering
positional roles. LDS (Longitudinal dimensionality
factor) was identified as the only that significantly differ
the groups of volleyball players. A group of central players
achieved significantly higher results than all the other
groups except the group of diagonal players. The research
results indicate that the morphological characteristics of
tested groups of volleyball players are similar to those of the other volleyball leagues or national teams which
points to valuable potential of tested players. It is
interesting that there was no significant difference
between the central and diagonal players and the fact is
that in most serious volleyball teams central and diagonal
players really are the highest ones. This is logical
considering the specific assignments of these players
during one volleyball match. Obtained informations may
serve as a normative values as well as a support in
directing players to a specific playing role in order to
optimize their situational effectiveness finally reaching an
optimal competition results in a sports career
