Abstract. The aim of this study was to determine relationship between
isometric tests and dynamic performance in bench press action. Subjects
of this study were 22 male students of Faculty of Sport and Physical Education
in Niš. The testing of isometric muscle force provided the values of maximum
voluntary force (Fmax), and four other indices of explosive force production
by muscle being tested (RFD, T30-70, T30-80, T30-90). Subjects were tested
in the isometric bench press machine in two different positions. All the
subjects were also tested in the classical bench press action. Performance
measure of dynamic performance was 1RM in classical bench press action.
The relationship between isometric and dynamic strength test was assessed
by Pearson's correlation coefficients. The correlation between the Fmax
in isometric testing and the 1 RM in bench press in our study in initial
position was r=0.16, and in final position r=0.33. The result of our study
confirmed the results of the previous mentioned studies that failed to
demonstrate high correlation between the isometric testing and the performance
task.

ISTRAŽIVANJE ODNOSA IZMEĐU RAZLIČITIH
PROCENA MIŠIĆNE SNAGE U AKCIJI POTISKA SA KLUPE
Sa ciljem utvrđivanja povezanosti izometrijskog i dinamičkog testa mišićne
snage u potisku sa klupe (bench press), organizovano je testiranje 22 studenata
Fakulteta sporta i fizičkog vaspitanja u Nišu. Iz izometrijskog
testiranja dobijena je vrednost maksimalne izometrijske sile (Fmax), i
vrednosti četri testa za procenu brzine razvoja sile u izometrijskim uslovima
(RFD, T30-70, T30-80, T30-90). Testiranje je sprovedeno u dve različite
pozicije na aparaturi za izometrijsko merenje sile prilikom potiska sa
klupe. Za procenu maksimalne dinamičke sile korišćen je 1RM prilikom
izbačaja sa klupe (Bench press). Relacija između izometrijskog
i dinamičkog testa snage je procenjena Pirsonovim koeficientom korelacije.
Korelacija između maksimalne izometrijske sile i 1RM u prvoj poziciji
je r=0.16, dok je u drugoj poziciji r=0.33. Ovi rezultati potvrđuju rezultate
brojnih studija koje nisu pronašle značajnu povezanost rezultata na izometrijskom
testu i dinamičkog zadatka.
