Abstract. The aim of this paper is to point out to the deficiencies and inconsistencies of the test for estimating muscle force. The sample of participants consisted of over 1000 fourth-grade elementary school boys and school girls and 300 high school sophomores. In this paper the focus of our interest is one of the tests which is a part of the Eurofit battery test. In fact, it is a test named "Endurance in pull-ups" which estimates the force of the arms and shoulders. Analyses of the obtained results indicate that the test does not have the required sensitivity, to discriminate the global pattern weakly. High coefficient values of the skewness variation value with a characteristic of extremely positive curvature, indicate that the motor task is rather difficult for most ten-year-olds. An analysis of the way in which the test is carried out indicates this test is just a standard one (performing on the same, predetermined protocol), but not standardized (the same one in the units of work). The measured physical value is not expressed in newtons (N), which are provided by the international system of physical value and its units. The paper proposes a way in which the test should be modified in order to have the necessary metric characteristics. The interpretation of the results and then the conclusions in kinesiology research, would scientifically be valid only in such a way.
Key words: Eurofit battery tests, endurance in pull-ups, force, metric characteristics.
METRIJSKE KARAKTERISTIKE MOTORIČKOG TESTA ZA PROCENU SILE RUKU I RAMENOG POJASA
Cilj rada je da se ukaže na nedostatke i nedoslednosti testa za procenu snage mišića. Uzorak ispitanika sačinjavalo je preko 1000 učenika i učenica četvrtih razreda osnovne škole i 300 učenika II razreda srednje škole.Predmet našeg interesovanja u ovom radu jeste jedan od testova koji su deo Eurofit baterije testova. Naime, radi se o testu Izdržaj u zgibu kojim se procenjuje sila ruku i ramenog pojasa. Analize dobijenih rezultata ukazuju da test ne poseduje potrebnu osetljivost, da slabo diskriminiše globalni uzorak. Visoke vrednosti koeficijenta varijacije vrednosti skjunisa sa karakteristikom izrazito pozitivne zakrivljenosti, ukazuje da je motorički zadatak težak za većinu desetogodišnjaka. Analiza načina na koji se test realizuje ukazuje da je ovaj test samo standardan (izvodi se na isti, protokolom tačno utvrđen način), ali ne i standardizovan (isti u jedinicama rada). Merena fizička veličina se ne izražava u mernim jedinicama njutnima (N) koje su predviđene međunarodnim sisitemom fizičkih veličina i njihovih jedinica. U radu se preporučuje način na koji bi test trebalo modifikovati, kako bi imao neophodne metrijske karakteristike. Tek u tom slučaju bi se interpretacija rezultata, a samim tim i zaključci u kineziološkim istraživanjima, učinili naučno valjanim.
Ključne reči: eurofit baterija testova, izdržaj u zgibu, sila, metrijske karakteristike.
