dc.description.abstractUspešno rešavanje takmiĉarskih situacija u sportu ĉesto zavisi od perceptivnih sposobnosti. Anticipacija i vreme reakcije kao aspekti perceptivnih sposobnosti predstavljaju faktore od kojih zavisi takmiĉarska uspešnost. Vreme reakcije se smatra bitnim elementom u sportovima koji zahtevaju brzo reagovanje na odreĊene spoljašnje draži. Jedan od primera takvih sportova je karate. Razlike u vremenima prostog i izbornog reagovanja meĊu sportistima razliĉitih nivoa na osnovu pregledane literature pokazale su se priliĉno nedosledne. Karate se posebno istiĉe u tom pogledu. Dobijanje relevantnih vremena reagovanja u mnogome zavisi od primenjene tehnologije i mogućnosti simuliranja realnijih zadataka (testova) u odnosu na takmiĉarske uslove. Uglavnom, dominiraju istraživanja koja se zasnivaju na korišćenju video tehnologije (snimci ili slajdovi). Osnovni nedostaci ovih istraživanja su vezani za realnost odgovora (pritisak ili otpuštanje tastera) na prikazane podsticaje. Na osnovu navedenog, proizašao je i opšti cilj, a to je da se uporedi brzina reagovanja kod karatista razliĉite specijalizacije merena korišćenjem savremene video tehnologije. Na osnovu opšteg cilja planirana su i sprovedena dva eksperimenta. U Eksperimentu 1 uĉestvovalo je 20 ispitanika (elitni karatisti i poĉetnici) sa ciljem da se uradi evaluacija novog video metoda za merenje vremena reagovanja u specifiĉnim sportskim situacijama. Glavna novina ovog metoda se odnosi na poboljšanje ekoloških uslova merenja, a odnosi se na realnost podsticaja (video snimak jednog udaraca rukom i jednog udarca nogom) i na realanost odgovora na isti (odgovarajuće odbrambene akcije). Prvi cilj u ovom eksperimentu je bio da se proceni pouzdanost njihovog vremena reagovanja dobijenih i u uslovima prostog i izbornog reagovanja, dok se drugi cilj odnosio na procenu osetljivosti dobijenih merenja uporeĊivajući posmatrano vreme reagovanja kod elitnih karatista i poĉetnika, kako u uslovima prostog reagovanja tako i u uslovima izbornog reagovanja...sr
dc.description.abstractSuccessful resolving of competitive situations in sport often depends on perceptual abilities. Anticipation and reaction time as aspects of perceptual skills are the actors which determine competitive efficiency. The reaction time is considered an essential element in sports that require a rapid response to specific external stimuli. Karate is an example of such sports. Differences in times of simple and choice reactions among athletes of different levels based on relevant references proved to be quite inconsistent. Karate stands out in this respect. Obtaining of relevant reaction time depends largely on the technology used and simulating realistic tasks (tests) with respect to competitive conditions. It is mainly dominated by research based on the use of video technology (tapes or slides). The main disadvantages of these investigations are related to the reality of response (pressure or release button) to the displayed incentives. The general objective also resulted from the aforesaid that is to compare the speed of reaction in the karateka of different specializations measured by using modern video technology. Base on the general objective, two experiments were planned and carried out. The first experiment involved 20 participants (elite karate athletes and beginners) with an aim to evaluate a novel video method for measuring the reaction time of the specific sport situations. The main novelty of this method relates to the improvement of environmental measurement conditions, and refers to the reality of incentives (video recording of one punch and one kick) and the reality of the response to it (appropriate defensive actions). The first objective of this experiment was to evaluate the reliability of their time response obtained in terms of simple and choice response, while the second aim referred to estimate of the sensitivity of measurements obtained by comparing the observed response time in elite karate athletes and beginners, both in terms of simple reactions and in terms of choice response. In the second experiment, the primary objective was to compare the speed of reaction with the karateka of different specializations measured by using modern video technology...en
