Abstract. The aim of this research has been to identify the relation between the motor coordination factor, latent volume dimension and body mass. The sample of participants consisted of 180 preadolescent female basketball players. The motor coordination ability has been estimated with the help of 3 motor tests (threading and leaping, agility in the air and the backward polygon), while the morphological characteristics were measured with the help of a battery of 6 anthropometric measures (body mass, forearm volume, outstretched arm volume, thigh volume, shin volume and abdomen volume). The obtained results were processed using the canonical correlation analysis. The results indicated the existence of only one statistically significant canonical pair factor, which explains 68% of variance, or a moderate correlation of two canonical components between the motor and morphological variables sets (Rc = .59), at the (p < .01) level of significance. The extracted canonical dimension in anthropometric space has been defined as the volume and body mass factor, and the canonical structure of coordination abilities has been interpreted as the canonical factor of body movement coordination. When analyzed partially, body mass (r= .95), forearm volume (r= .89) and threading and leaping (r= .48) variables have mostly contributed to the structure of this canonical dimension. The achieved variance percentage (Rc² = .68) assumes relevant prediction possibility relation between two linear variable combination systems of female basketball players, younger pioneers and mini-basketball players. The obtained information about the one-componential canonical model of the motor and morphological structure of female players has its practical application in selection improvement, as well as in training female basketball players’ operators modeling.
Key words: female mini-basketball players, motor tests, anthropometric measures, canonical relations
POVEZANOST KOORDINACIJE POKRETA I VOLUMINOZNOSTI I MASE TELA KOŠARKAŠICA UZRASTA 11–12 GODINA
Cilj istraživanja bio je ispitivanje relacija koordinacije pokreta i latentne dimenzije voluminoznosti i mase tela. Uzorak ispitanika činilo je 112 košarkašica u predadolescentnom uzrastu. Sposobnost koordinacije pokreta procenjena je pomoću 3 motorička testa (provlačenje i preskakivanje, okretnost u vazduhu i poligon natraške), dok su morfološke karakteristike merene pomoću baterije od 6 antropometrijskih mera (masa tela, obim podlaktice, obim opružene nadlaktice, obim natkolenice, obim potkolenice i obim trbuha). Dobijeni podaci obrađeni su kanoničkom korelacionom analizom. Rezultati su ukazali na egzistenciju samo jednog statistički značajnog para kanoničkih faktora, koji objašnjava 68% varijanse, odnosno umerenu korelaciju između skupova motoričkih i morfoloških varijabli (Rc = ,59), na nivou značajnosti (p < .01). Ekstrahovana kanonička dimenzija u antropometrijskom prostoru definisana je kao faktor volumena i mase tela, a struktura u motoričkom prostoru interpretirana je kao kanonički faktor koordinacije pokreta. Parcijalno analizirajući, strukturi ove kanoničke dimenzije najviše su doprinele varijable: masa tela (r = ,95), obim podlaktice (r = ,89) i provlačenje i preskakanje (r = ,48). Izračunati procenat varijanse (Rc² = ,68), pretpostavlja mogućnost relevantne predikcije povezanosti dva sistema linearnih kombinacija varijabli kod košarkašica mini-basketašica. Dobijene informacije o jednokomponentnom kanoničkom modelu motoričke i morfološke strukture svoju aplikaciju u praksi mogu da imaju u unapređenju selekcije i modeliranju trenažnih operatora košarkašica.
