Abstract. On a sample of 112 boys and girls who had previously
been
selected for gymnastics from six of the elementary schools of Niš, the
metric characteristics of 19 situational-motor coordination tests which
are known to date and which have been used in the selection process in
gymnastics in eight countries in Europe and the former Yugoslav
republics
have been determined. The authors have classified the aforementioned
measuring
instruments into five hypothetical areas of coordination including: The
performance speed of complex motor tasks (4); Agility (3); Rhythm
coordination
(4); Precise performance of complex motor tasks (6); The precise
management
of hand motions in space (2). This paper presents the results of the
objectivity
of measuring instruments by calculating Pearson's correlation
coefficient
and by implementing Hotelling's canonical-correlational analysis for
each
of the tests for the purpose of evaluating the objectivity of the
analyzed
composite tests. Two sets of variables, between which a canonical
correlation
was found to exist and therefore the objectivity of the composite test
represented the course three measurings which were noted on the part of
two measurers in an actual test on involving the same sample of
examinees.
Bearing in mind that the value of the first pair of canonical factors
best
explains the connection between the two systems of variables, the first
canonical equation root was used as the indicator for the objectivity
of
the given composite test. The aforementioned results indicate that 18
out
of the 19 measuring instruments for the evaluation of situational-motor
coordination in gymnastics have significant values when it comes to
objectivity
and can be recommended for practical use. Only one of the tests for the
evaluation of the ability to precisely perform complex motor tasks -
the
Standing jump accompanied by asymmetrical motions of the extremities
(SJSE)
was classified among the group of measuring instruments of unacceptable
objectivity and requires additional restandardization of the
measurement
procedure.
Key words: gymnastics, objectivity, situational-motor
coordination, measuring instruments, canonical-correlational analysis.
OBJEKTIVNOST MERNIH INSTRUMENATA

MOTORIČKE KOORDINACIJE U SPORTSKOJ GIMNASTICI
Na uzorku od sto dvanaest dečaka i devojčica prethodno selekcionisanih
za sportsku gimnastiku iz šest osnovnih škola grada Niša utvrđene su
metrijske
karakteristike za 19 situaciono- motoričkih testova koordinacije koji
su
do sada poznati i primenjivani u selekciji za sportsku gimnastiku u
osam
zemalja Evrope i bivšim jugoslavenskim republikama. Autori su pomenute
merne instumente svrstali u pet hipotetskih područja koordinacije i to
: Brzina realizacije složenih motoričkih adataka(4) ; Agilnost (3) ;
Koordinacija
u ritmu (4); Tačno realizovanje složenih motoričkih zadataka (6); Tačno
upravljanje pokretima ruku u prostoru(2):
U ovom radu izneti su rezultati objektivnosti mernih instumenata tako
što je izračunat Pirsonov koeficijen korelacije a zatim je primenjana
Hotellingova
kanoničko-korelaciona analiza za svaki test u cilju procene
objektivnosti
analiziranih kompozitnih testova. Dva seta varijabli, između kojih je
utvrđena
kanonička korelacija, a time i objektivnost kompozitnog testa,
predstavljala
su tri merenja, registrovana od strane dva merioca, u aktuelnom testu,
na istom uzorku ispitanika. Imajući u vidu da vrednost prvog para
kanoničkih
faktora najbolje objašnjava povezanost dva sistema varijabli, prvi
koren
kanoničke jednačine poslužio je kao pokazatelj objektivnosti datog
kompozitnog
testa. Pomenuti rezultati ukazuju da 18 od 19 mernih instrumenata za
procenu
situaciono-motoričke koordinacije u sportskoj gimnastici imaju značajne
vrednosti koeficijenata kada je u pitanju objektivnost i mogu se
preporučiti
za primenu u praksi. Samo jedan test za procenu sposobnosti za tačno
realizovanje
složenih motoričkih zadataka - Skokovi na mestu sa simetričnim radom
ekstremiteta
(SMSE) je svrstan u grupu mernih instrumenata neprihvatljive
objektivnosti
i zahteva dodatnu restandardizaciju mernog postupka.
Ključne reči: Sportska gimnastika, objektivnost,
situaciono-motorička
koordinacija, merni instrumenti, kanoničko-korelaciona anliza.
