Abstract

The purpose of the work is to check the reliability of the evaluation the ability of the isometric force of the arms extension muscles, by doing the bench - press test in the women police officers. A test for that purpose included 22 women probationers who attended the Police College in Zemun. For every probationer there was a specially developed hardware - software system there were exemplary results which matched the maximal force (Fmax) arms extension and the rate of force developement (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 this test on a general level is objective and reliable on the Canonical R = 0.9451 level from 94.51%. In comparison to partial objectivity and reliability, in function of observed parameters of the muscle contraction, it has been submitted that Fmax is reliable on the level of 79.4% (p = 0.000), ImpF is reliable on the level of 50.56% (p = 0.000), Kmax is reliable on the level of 33.58% (p = 0.0046), and tFmax is reliable on the level of 37.5% (p = 0.0025), while for the RFD force, fulfilled in the given system of the demonstrating (isometric), for the given sample (women police officers age D 22+/- 1.5 year) and the group of the muscles (the arms extension muscles) is not confirmed statistically significant reliability measured by the method test - retest (R2 = 0.161, p = 0.064). Because of the high general reliability, the offered method of the testing of maximal force and the parameter of muscular force, is recommended for the practical usage. In the next research, it is necessary to define measuring features of the given test too, and especially measure values for the RFD force valuation.
