Abstract
The purpose of this paper is to check the reliability of the evaluation of the ability of the isometric force of the arms extension muscles, by doing the bench-press test on the police officers. For that purpose the test was conducted on 44 male students of the Academy of Criminalistic and Police Studies in Zemun. Specially for this purpose developed hardware and software system was used to sample results matching the maximal force (Fmax) of arms extension and the rate of force development (RFD), impulse of the muscle force (ImpF), coefficient of muscle activation velocity (Kmax) and the time of the force creating (tFmax). The results have shown that the coefficient of determination is high for all the observed parameters - for Fmax (R²=0.87) for RFD (R²=0.16), for Kmax (R²=0.36), for tFmax (R²=0.15), except for ImpF (R²=0.06). Because of its high reliability (R²=0.95), offered method of the testing of maximal force and the parameters of muscular force is recommended for the practical ...usage.

Cilj rada je provera pouzdanosti (relijabilnosti) procene karakteristika izometrijske sile mišića opružača ruku primenom testa benč-pres kod policajaca. U tu svrhu izvršeno je testiranje koje je sprovedeno na 40 ispitanika muškog pola, studenata Kriminalističko-policijske akademije u Zemunu. Za svakog ispitanika posebno, razvijenim hardversko-softverskim sistemom, uzorkovani su rezultati koji odgovaraju maksimalnoj sili (Fmax) opružača ruku i parametri brzine stvaranja sile (RFD), količine saopštenog kretanja (ImpF), brzine uključenja mišića (Kmax) i vreme generisanja sile (tFmax). Rezultati su pokazali da je dati test na generalnom nivou objektivan i pouzdan (Conical R=0.95). U odnosu na parcijalnu objektivnost i pouzdanost utvrđeno je da je koeficijent determinacije za Fmax R2 = 0,87 (p=0,000), za RFD R2 = 0,16 (p=0,009), za Kmax R2 = 0,36 (p=0,000) i za tFmax R2 = 0,15 (p=0,013), dok za ImpF nije utvrđena statistički značajna pouzdanost (R2 = 0,06, p=0,099). Generalno, predloženi me...tod testiranja maksimalne sile i parametara mišićne sile je pokazao visoku pouzdanost, pa se preporučuje za upotrebu u praksi.
