Abstract

The object of this paper is to evalue the reliability of a number of test in measuring the contractile potential of elbow flexors and extensors in policemen during the anaerobic repetitive muscular exertion of maximum intensity. This has been done by testing two groups of 36 students of the Police Academy in Belgrade. One group was subjected to the pull-ups test in four variations: measuring the number of pull ups executed in 10 seconds on the one hand, and measuring the amount of time needed to make 5, 8 and 10 pull ups. The second group has been asked to perform push ups, in six variations: measuring the number of push up done in 10, 15 and 20 seconds, as well as measuring the time needed to do 10, 15 and 20 push ups. The results pointed out that the most reliable test to measure the contractle potential of elbow extensors during anaerobic (glikolitic-lactic) repetitive muscular exertion is the test measuring the time needed to do 15 push ups, while the best test for elbow flexors is the one measuring the time needed to perform 10 pull ups. Both tests showed a high degree of reliability reaching respectively 97.7 and 96.4% and are therefore recommended for practical use. Cilj rada je procena testa kojim se najpouzdanije meri kontraktilni potencijal mišića pregibača i opružača ruku kod policajaca ispoljen u anaerobnom režimu repetativnog mišićnog naprezanja maksimalnim intenzitetom. U tu svrhu izvršeno je testiranje koje je sprovedeno sa dve grupe od 36 studenata Policijske akademije u Beogradu. Jedna grupa je testirana primenom testa 'zgibovi' i to sa četiri varijante: broj urađenih zgibova za 10 sekundi, kao i vreme potrebno da se izvede 5, 8 i 10 zgibova. Druga grupa je testirana primenom testa sklekovi i to sa šest varijanti: broj urađenih sklekova za 10, 15 i 20 sekundi, kao i vreme potrebno da se izvede 10, 15 i 20 sklekova. Rezultati su pokazali da se kod testirane populacije policajaca kontrakt ili potencijal mišića opružača ruku, ispoljen u anaerobnom režimu (glikolitičko-laktatnom) repetativnog mišićnog naprezanja maksimalnim intenzitetom, najbolje procenjuje testom - vreme potrebno da se izvede 15 sklekova, dok se kod pregibača ruku najbolje procenjuje testom -vreme potrebno da se izvede 10 zgibova. Oba testa su pokazala visoku pouzdanost merenja na nivou od 97.7% i 96.4%, respektivno, pa se preporučuju za upotrebu u praksi.
