Abstract

U procesu sportske pripreme postoje razne metode razvoja snage i eksplozivnih svojstava sportaša. Jedna od popularnih metoda je kontrastni trening u kojem sportaš najčešće izvodi čučanj kao vježbu jakosti te nakon određene pauze, koja može trajati od pet do 15 minuta, vježbu za razvoj eksplozivne snage ili brzine. Upravo je duljina pauze jedan od nedostataka ove metode treninga jer se ta pauza smatra gubitkom vremena. Stoga treba utvrditi postoji li bolji način da se ta pauza iskoristi. Svrha... More ove studije bila je ispitati utjecaj potiska s ravne klupe (BP), tijekom pauze, na efekte kontrastnog treninga donjih ekstremiteta. Ispitanicima su u inicijalnom testiranju izmjereni snaga i visina skoka s pripremom (CMJ), bez i sa zamahom ruku. Ista mjerenja skokova su ponovljena osam minuta nakon čučnja (SQ) 3RM-a s 85% od prethodno izmjerenog 1RM-a te nakon SQ i BP koji se izvodio dvije minute nakon SQ, također 3RM-a s 85% od prethodno izmjerenog 1RM-a. Za statističku analizu korištena je deskriptivan statistika, Pearsonova korelacija i t-test. Nakon obrade podataka utvrđeno je da, kod obje varijante skokova (CMJ i CMJmax) ne postoji statistički značajna razlika između inicijalne visine skoka i skoka nakon SQ te SQ i BP. Nadalje, statistički značajna razlika postoji između inicijalnih vrijednosti snage skokova i snage skokova nakon SQ te SQ i BP kod CMJ, dok je kod CMJmax, statistički značajna razlika samo između inicijalnih vrijednosti i vrijednosti snage nakon SQ i BP. Kod svih varijabli gdje postoji statistički značajna razlika, inicijalne vrijednosti su veće od onih nakon SQ ili SQ i BP. Less

Abstract (english)

There are plenty methods for developing power and explosiveness in athletes in physical preparation. One of the popular methods is contrast training in which the athlete performs e.g. squats, as strength exercise, and after certain rest period, which can least from five to 15 minutes, an exercise for explosive power or speed development. This long rest period is one of the imperfections of the contrast training, because it is considered as a time loss. In that case, it should be determined... More if there is any better way to use that rest period. The purpose of this study was to determine the impact of bench press (BP) exercise, during the rest period, on the efficiency of the lower body contrast training. Subjects performed initial countermovement jump (CMJ) with and without arm swing, jump height and power were measured. The same measures were performed after 3RM squat (SQ) with 85% of initially established 1RM, and after SQ and BP, which was performed two minutes after SQ, also with 3RM with 85% of initially established 1RM. Descriptive statistic, Pearson’s correlation and t-test were used in statistical analysis. After data processing, it was confirmed that there is no statistically significant difference between initial jump height and jump height after SQ or SQ and BP at both jump variants (CMJ and CMJmax). Furthermore, there is statistically significant differences between initial jump power and jump power after SQ or SQ and BP at CMJ, but at CMJmax, statistically significant difference is only present after SQ and BP variation. At all variables where statistically significant difference is present, initial values are higher than those after both conditions, SQ or SQ and BP. Less
