摘要：The goal of this research was to determine the differences between results scored on the entrance exam andresults at the end of freshmen year of studies in muscular force of the legs’ extensors of students. On thesample of 119 students (39 females and 80 males aged from 19 to 21) is followed by the change of thespeed force of the extension force of muscles expressed by the length of the long jump from the site, createddue to the effect of teaching from the subject of Special Physical Education 1 (SPE1) which to be realized onthe freshmen year of basic academic studies at the Criminalist Police University (CPU) in Belgrade. Fordetermination of the significance of differences between the variables observed on initial and finalmeasurement the Student’s t-test is used for dependent samples. The results in this research on the sampleof female students (N=39) had shown up that after the teaching realized from the subject of SPE1statistically significant changes of absolute values of the above mentioned variable had not been achieved onfinal measurement (M=182.2 cm, SD=11.67, p>0.05) in comparison to the values registered at the initialmeasurement (M=179.9 cm, SD=14.94). However the results that are obtained on the sample (N=80) hadshown that after teaching realized from the subject of SPE1 the statistically significant changes of theabsolute values of the above mention variable had been occurred on the final measurement (M=237.4 cm,SD=15.56, t=-2.24, p>0.05) in relation to the values that are registered on the initial measurement(M=233.9 cm, SD=18.75).
