Istraživanje je provedeno na osamnaest (18) muških studenata Kineziološkog fakulteta Sveučilišta u Zagrebu u kojem se mjerila visina skoka, trajanje kontakta s podlogom i reactive strength index (RSI). Prosječna dob ispitanika je bila 23.56 ± 1.54 godina, tjelesna masa 83.11 ± 11.37 kilograma, a visina 181.22 ± 6.59 centimetara. Mjerenje je provedeno aplikacijom MyJumpLab. Ispitanici su provodili po pet kontinuiranih sunožnih i jednonožnih skokova iz stopala s obućom i bez nje, dok su skokove s pripremom i bez pripreme s obućom i bez obuće izvodili tri puta na način da svaki skok zasebno izvode. Trajanje kontakta s podlogom i RSI mjereni su samo za skokove iz stopala jer skokovi s pripremom i bez pripreme su izvođeni zasebno, stoga nije ni RSI vrijednost mjerena. Vrsta obuće nije bila prethodno definirana stoga su ispitanici testiranje provodili u vlastitoj obući po osobnom izboru. Nakon mjerenja uspoređivani su podaci u jednakim motoričkim zadacima s obućom i bez obuće. Rezultati su pokazali razlike između skokova s obućom i bez nje, no te razlike nisu bile statistički značajne osim u prosječnoj visini skokova iz stopala s obućom (SISOV) i prosječnoj visini skokova bez obuće (SISBV) (p=0,04, t=2.18) . Usporedba rezultata motoričkih zadataka s obućom i bez obuće pokazala je u većini varijabli minimalne razlike što sugerira da bi pliometrijski trening trebao dati jednake adaptacije bilo da se provodi s obućom ili bez obuće budući da se visina, trajanje kontakta s podlogom te RSI značajno ne mijenjaju posredstvom obuće u većini mjerenih varijabli.
Abstract (english) The purpose of this study was to establish if and to what extent footwear affects the values of jumps. The research was conducted on eighteen (18) male students of the Faculty of Kinesiology of the University of Zagreb, in which the height of the jump, the ground cotact time and the reactive strength index (RSI) were measured. The average age of the subjects was 23.56 ± 1.54 years, body weight 83.11 ± 11.37 kilograms, and height 181.22 ± 6.59 centimeters. The measurement was performed using the MyJumpLab application. The subjects performed five continuous two-legged pogo jumps and five one-legged pogo jumps with and without shoes, while they performed countermovement jump and squat jump with and without shoes three times in such a way that they performed each jump separately. Ground contact time and RSI were measured only for pogo jumps because countermovement jump and squat jump were performed separately, therefore the RSI value was not measured either. The type of footwear was not pre-defined, so the test subjects carried out the testing in their own footwear of personal choice. After the measurements, data were compared in the same motor tasks with and without shoes. The results showed differences between jumps with and without shoes, however, these differences were not statistically significant, with the exception of in the average height of two-legged pogo jumps with shoes (SISOV) and the average height of pogo jumps without shoes (SISBV) (p=0.04, t=2.18 ). Comparison of the results of motor tasks with and without shoes showed minimal differences in most variables, which suggests that plyometric training should provide equal adaptations whether it is performed with or without shoes, since height, ground contact time, and RSI do not significantly change through footwear in most measured variables.
