Abstract

Istraživanje je provedeno na Kineziološkom fakultetu u Zagrebu sa ciljem utvrđivanja razlika u biomehaničkim pokazateljima dubinskih skokova. Uzorak ispitanika činilo je 20 sportaša prosječne starosti 22,3 ± 7,2 godina, tjelesne mase 79,4 ± 7,3 kg i tjelesne visine 181,6 ± 7,2 cm. Dobivenim rezultatima određeni su deskriptivni pokazatelji (Min, Maks, AS, SD), a Wilcoxonovim testom ranga utvrdile su se statističke značajne razlike unutar varijabli na pojedinoj visini saskoka. Utvrđena je statistički značajna razlika u trajanju kontakta s podlogom između visina 40/60 cm, odnosno rezultati saskoka sa 60 cm trajali su u prosjeku dulje od onih sa 40 cm. Nadalje, izmjereni rezultati pokazali su veliko razlikovanje visine skoka između saskoka sa platforme visine 20/40 te 40/60 cm. Povećanje visine platforme proporcionalno je povećavalo i visinu skoka. Ostale varijable nisu pokazale značajne razlike. Trajanje ekscentrične i koncentrične kontrakcije te kut amortizacije u koljenu u prosjeku nije variralo s obzirom na povećanje visine saskoka.

Abstract (english)

The research has been realized on Faculty of Kinesiology in Zagreb with goal of determining differences in biomechanics parameters of drop jumps. Sample has been made of 20 athletes average age 22,3 ± 7,2 years, weight 79,4 ± 7,3 kg and height 181,6 ± 7,2 cm.
The results were analyzed with application of method of descriptive statistics (Min, Max, Mean, SD) and compared with Wilcoxon rang test which gave significant differences in certain variables on each drop jump height.
Significant statistical difference in ground contact time were obtained between 40/60 cm drop jump height, apropos results from 60 cm lasted on average longer from those with 40 cm. Furthermore, measured results showed high difference in jump height between drop jumps from 20/40 & 40/60 height. Increasing drop jump height resulted in increased jump height. Other variables did not show significant differences. Duration of eccentric, concentric contraction and angle of knee flexion did not vary in average regarding to increase of drop height.
