Reliability of the evaluation of characteristics of isometric force of the arm extension muscles by doing the bench-press test on police officers
Criminology and Police Academy

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.
