Differences in motor abilities of upper primary students regarding morphological features

Istraživanje je provedeno na uzorku od 72 učenika i učenica Osnovne škole ''Petrijevci'' u Petrijevcima. Uzorak je naknadno podijeljen u dva subuzorka s obzirom na količinu masnog tkiva te na količinu mišićne mase. Uzorak varijabli je činilo 6 testova za procjenu motoričkih sposobnosti i jedan test za procjenu funkcionalnih sposobnosti te dvije antropometrijske mjere (tjelesna visina i tjelesna masa) iz kojih je izračunat index tjelesne mase te dvije morfološke mjere: količina masnog tkiva i količina mišićne mase. Cilj ovog istraživanja je bio utvrditi postoje li razlike u motoričkim sposobnostima učenika viših razreda osnovne škole s obzirom na morfološka obilježja te ispitati njihovu međusobnu korelaciju. Dobiveni rezultati ukazuju na razlike u motoričkim sposobnostima s obzirom na postotak masnog tkiva te mišićne mase u gotovo svim sposobnostima, osim u motoričkim sposobnostima brzine frekvencije pokreta te gibljivosti. Također je dokazana korelacija između motoričkih sposobnosti i morfoloških karakteristika u odnosu na druge motoričke sposobnosti te morfološke karakteristike, osim u motoričkim sposobnostima brzine frekvencije pokreta te gibljivosti.This research was conducted on a sample of 72 pupils of elementary school in Petrijevci. The sample was later on divided into two categories, regarding two morphological criteria: the percentage of body fat and the percentage of muscle in a body. The sample of variables was consisted of six tests for evaluating motor skills and one test to determine the functional capability. Also two anthropometric measures were determined (body height and weight) from which, BMI (body mass index), the percentage of body fat and the percentage of muscle were extrapolated. The aim of this research was to determine if there are any differences in motor skills and morphological characteristics when considering the percentage of body fat and muscle in pupils attending higher grades of elementary school. The goal was also to determine if there is a correlation between motor skills and morphological characteristics. The results indicate that there is a difference between motor skills and morphological characteristics, when considering body fat and muscle, in all but two motor skills, the speed of movement frequency and in flexibility. The outcome of this research exhibits correlation between motor skills and morphological characteristics concerning other motor skills and morphological characteristics in all of them, except in flexibility and the speed of movement frequency
