Projekat

Efekti primenjene fizičke aktivnosti na lokomotorni, metabolički, psiho-socijalni i vaspitni status populacije R Srbije (MPNTR - 47015)

Sažetak

U poređenju sa odraslima, deca imaju sporije prosto (PVR) i izborno (IVR) vreme reakcije (VR) na prostu i izbornu vizuelnu draž. Na osnovu podataka iz dostupne literature, može se zaključiti da bi razlog mogla biti povezanost godina starosti sa brzinom obrade informacija, ali i da drugi faktori, poput slabije pažnje, na primer, mogu imati uticaja. Neka istraživanja pokazuju da karate favorizuje razvoj kognitivnih funkcija, uključujući i VR. Stoga je cilj ove studije bio da utvrdi da li između dečaka i devojčica preadolescentskog i ranog adolescentskog uzrasta, na učeničkom i predmajstorskom stepenu obuke u karateu, postoje razlike za prosto i izborno vreme reakcije. Testirano je 78 ispitanika podeljenih u četiri subgrupe, u odnosu na pol i stepen obučenosti, primenom posebno dizajniranog softvera za merenje VR, razvijenog u programskom paketu LabVIEW 2012. Dvofaktorskom analizom varijanse (Two-way ANOVA) utvrđeno je da nema razlika između rezultata dečaka i devojčica ostvarenih za PVR, ali da su one značajne na nivou subuzoraka po kriterijumu majstorstva. Kada je u pitanju IVR, razlike su utvrđene na nivou subuzorka dečaka, kao i između polova na učeničkom nivou obuke. Ne može se sa sigurnošću tvrditi da li su dobijene razlike posledica treninga ili nekih drugih fiziološko-kognitivnih fenomena, odnosno procesa sazrevanja. Stoga bi buduća istraživanja morala da obuhvate širi uzorak - populaciju neaktivne, kao i dece uključene u druge sportove.
