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.
Key words:  Isometric tests, dynamic performance, relationship, muscle force

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.
