Abstract

Vertikalnim profilom sile i brzine utvrđujemo nedostatak sile ili brzine u vertikalnim skokovima odstupanjem od optimalnog profila kako bi mogli preciznije utvrditi što nedostaje sportašu kod njegovih skokova. U ovome radu prikazane su razlike između protokola za određivanje sile ili brzine izvedene s šipkom na ramenima i s bučicama sa strane tijela. U ovome radu pokušalo se dati odgovore ima li razlike u odrađivanju dva ista profila s različitim načinima opterećenja. Uzorak ispitanika se sastojao od 18 studentica Kineziološkog fakulteta Sveučilišta u Zagrebu. Istraživanje je provedeno u Sportsko dijagnostičkom centru Kineziološkog fakulteta. Mjerenje vertikalne visine skoka provedeno je na platformi za mjerenje sile KiJump (Kistler, Švicarska, a za obradu podataka je korišten sustav MARS), a rezultati su izračunati u proračunskoj excel tablici. Analizirane su razlike između teoretske maksimalne sile, teoretske maksimalne brzine, maksimalne snage, indeksa omjera razlike između optimalnog i dobivenog profila te postotak odstupanja od optimalnog profila, dobivena je razlika između svih varijabli osim u varijabli maksimalna snaga. Rezultati su ukazali na statističku značajnu razliku između dva profila, no, dobiveni rezultati nisu prikazali istosmjerno profiliranje kod izvođenja profila sa šipkom u odnosu na izvođenje s bučicama. S obzirom da je ovo prvo istraživanje u kojem su korištene bučice kao alat u izvođenju vertikalnih skokova kod određivanja vertikalnog profila odnosa sile i brzine potrebno je provesti još nekoliko istraživanja u kojima bi mogli još preciznije utvrditi vertikalne profile odnosa sile i brzine.

Abstract (english)

Considering the popularity of the vertical force velocity profile, this thesis presents the differences between the two force velocity profile performed with a bar on the shoulders and with dumbbells on the side of the body. The study focuses on finding the difference in performing two same profiles with different load modes. The sample consisted of 18 female students of the Faculty of Kinesiology, University of Zagreb (age 22.8±2.2, body height 166.6±6.3, body mass 62±6.8, fat percentage 18.7±5.4). The research was conducted in the Sports Diagnostic Center at the Faculty of Kinesiology. The measurement of vertical jump height was measured on the KiJump (1D MARS system) force measurement platform, and the results were calculated in an excel spreadsheet. A statistically significant difference was found between maximum force, maximum velocity, the ratio index of the difference between optimal and obtained profile and percentage of deviation from the optimal profile. On the other hand, there was no statistically significant difference for the maximum power. The results showed a statistically significant difference between the two profiles, but we did not get what was expected, which is that the deficiencies in force and velocity will be in the same direction with dumbbells and with the bar. Performing a force velocity profil with dumbbells is much more practical than with a barbell, but it is insufficiently researched and reliable to be able to determine athletes' lack of force or velocity.
