Sažetak
Uzorak ispitanika obuhvatio je 20 studentkinja Fakulteta sporta i fizičkog vaspitanja Univerziteta u Nišu. Istraživanje je podrazumevalo primenu skoka iz saskoka u Sportskoj gimnastici, sa dve različite visine (40 i 50cm) sa elastične podloge. Predmet istraživanja predstavljali su dinamički parametri kretanja utvrđeni primenom uređaja Myotest, prilikom protokola skoka iz saskoka, tzv. Drop Jump-a (DJ): visina (u cm), snaga (u W/kg), sila (u N/kg) i brzina (u cm/s). Dobijeni podaci statistički su obrađeni primenom deskriptivne statistike, metode analize varijanse i kanoničko diskriminativne analize. Može se zaključiti da su rezultati bili bolji u svim parametrima kada je skok iz saskoka izvođen sa visine sa visine od 50cm. To se odnosi na numeričke vrednosti, a statistička značajnost je utvrđena samo kod parametra power (p=0.00).
Abstract
The sample of participants included 20 female students from the Faculty of Sport and Physical Education in Niš. The research involved the use of the drop jump in sports gymnastics, performed from two different heights (40 and 50cm) from an elastic surface. The subject matter of actual research were the dynamic parameters of movement determined during the so-called drop jump (DJ), using the Myotest apparatus to measure the: height (in cm), power (in W/kg), force (in N/kg) and velocity (in cm/s). The obtained data were statistically processed by using the Descriptive statistics, the ANOVA and the Canonical-discriminant analysis. It was concluded that the results were better for all the studied parameters, when the Drop Jump was performed from a height of 50cm. This refers to the numerical parameters, but the statistical significance was determined only for the power parameter (0.00).
