S obzirom na konstantnu promjenu pravila zadnjih godina s ciljem ubrzavanja igre mijenjaju se i fizički zahtjevi za rukometaše. Jedna od često korištenih kretnih struktura u samoj igri je i skok bio vertikalan ili horizontalan. Upravo zbog velikog broja skokova treneri moraju biti sposobni u pripremnom dijelu treninga pripremiti lokomotorni sustav sportaša na sva opterećenja tijekom utakmice. Cilj ovog istraživanja je utvrditi postoji li statistički značajan utjecaj zagrijavanja pjenastim valjkom na izvedbu eksplozivne snage tipa skočnosti kod rukometaša adolescenata. Istraživanje je provedeno u Zagrebu na 20 mlađih kadeta muškog rukometnog kluba Sesvete prosječne dobi 14,30 ± 0,47 godina, visine 179,70 ± 7,52 centimetara i težine 67,20 ± 10,47 kilograma. Istraživanje se provodilo u tri faze. U prvoj fazi istraživanja ispitanici su inicijalno testirani u svih 5 varijabli za procjenu skočnosti, druga faza sastojala se od valjanja regije trupa i donjih ekstremiteta dok su u trećoj fazi ponovno testirani u svim varijablama, s naglaskom da treća faza nije trajala duže od 20 minuta nakon završetka druge faze. Druga i treća faza provodile se su kombinirano 24 sata nakon prve faze. Za procjenu vertikalne skočnosti korišten je test skok u vis s mjesta, za procjenu horizontale skočnosti korišteni su testovi: skok u dalj s mjesta, skok s noge na nogu, pravolinijski troskok s noge na nogu i skok s noge na nogu s promjenom smjera. Statističkom obradom podataka utvrđeno je kako samomasaža pjenastim valjkom statistički negativno (< 0,03) djeluje na vertikalnu skočnost kod rukometaša adolescenata dok je njezin učinak na horizontalnu skočnost u svim testovima pozitivan no nije statistički značajan.
Abstract (english) Handball is a team sport which has a lot tehnical tactical elements. Taking in the consideration that the rules are constantly changing, which has a goal to speed up the game, physical needs of players are also changing. One of the most used structures in the handball game is vertical or horizontal jump. Because of the very high number of jumps, coaches must be able to prepare athletes for physical strain. The goal of this research is to determine if there is a signicicant statistical variable warming up with the foam roller on explosive vertical ability of young handball players. Research was conducted in Zagreb, on 20 young handball players from MHC Sesvete aged 14,30 ±, 0,49 years, height 179,70 ± 7,52 cm, weight 67,20 ±10,47 kg. Experiment was conducted in three phases. In the first phase players were tested in all five variables for determining average jumping ability, second phase included foam rolling core and lower body parts, while in the third phase , all players were again tested with all variables, it was importat that third phase must finished no loger than 20 minutes after second phase. Second and third phase were conducted 24 hours after first phase. For determination average vertical jumping ability was used Sargent jump. For testing the horizontal jump used were tested: long distance standing jump, single leg hop test, triple hop test and crossover triple hop test (last three tests were measured with both feet). Using statistical processing of the data, it was determinated that foam rolling has a significant negative effect on vertical jumping ability (p < 0,03), while its effect on horizontal jumping ability is positive in all tests but not significant.
