Abstract

Motoričke sposobnosti vaţan su aspekt uspjeha u svakom sportu. Cilj ovog istraţivanja je utvrditi utjecaj specifičnog akutnog umora na ciljane motoričke sposobnosti mladih taekwondoaša i rizika od nastanka ozljeda. Istraţivanje je provedeno na 17 mladih taekwondoaša, prosječne dobi 12,47 ± 1,33. Ispitanici su aktivni sportaši te su uključeni u redovni sustav natjecanja. Ispitanici su testirani u 4 testa, kojima se procjenjivala agilnost, eksplozivna snaga, fleksibilnost i dinamička ravnoteţa... More prije i poslije protokola umaranja. Za procjenu agilnosti koristio se test koraci u stranu (MAGKUS), za procjenu skočnosti koristio se sargent test (MESSAR), za procjenu fleksibilnosti koristio se test prednoţenja iz stojećeg stava (MFLPSS), a za procjenu dinamičke ravnoteţe koristio se test mirnog stajanja na balans platformi gdje su se kod prikaza rezultata koristile dvije varijable; ukupno prijeĎena antero-posteriorna udaljenost (PUT) i prosječno kvadratno odstupanje od početne točke (RMS). Nakon inicijalnog testiranja nad ispitanicima proveden je specifičan protokol umaranja koji se sastojao od 6 jednominutnih borbi s pauzom od jedne minute izmeĎu njih. Kako bi se provjerila uspješnost protokola koristila se modificirana borgova skala za procjenu opterećenja, s bodovima od 0 (umor nije prisutan) do 10 (prisutan je najveći mogući umor). Rezultati modificirane borgove skale pokazuju uspješnost protokola s prosječnim bodovima 8,41 ± 0,76. Razlika prvog i drugog mjerenja testa MAGKUS pokazuje nam da postoji statistički značajno smanjenje rezultata (t=-9,38, p=0,00). Razlika prvog i drugog mjerenja testa MESSAR takoĎer ukazuju na statistički značajno smanjenje rezultata (t=7,88, p=0,00). S druge strane razlika prvog i drugog mjerenja rezultata MFLPSS ukazuje na statistički značajno poboljšanje rezultata (t=-5,94, p=0,00). Rezultati testa za procjenu dinamičke ravnoteţe prikazani su kroz dvije varijable te se kod obje varijable vidi smanjenje rezultata koje nije statistički značajno; PUT (Z=0,64, p=0,52) i RMS (t=-1,45, p=0,17). Provedbom istraţivanja i analizom rezultata zaključeno je kako akutni umor negativno utječe na sve motoričke sposobnosti osim fleksibilnosti na koju ima pozitivan učinak. Produkt toga je povećani opseg pokreta i smanjena kontrola pokreta što u konačnici povećava rizik od nastanka ozljede. Less

Abstract (english)

Motor skills are an important aspect of success in any sport. The aim of this research is to determine the impact of specific acute fatigue on the targeted motor skills of young taekwondo players and the risk of injury. The research was conducted on 17 young taekwondo players, average age 12,47 ± 1,33. The respondents are active athletes and are included in the regular competition system. The subjects were tested in 4 tests that assessed agility, explosive strenght, flexibility and dynamic... More balance before and after the fatigue protocol. To assess agility, the step-to-side test (MAGKUS) was used, to assess explosive strenght, the Sargent test (MESSAR) was used, to assess flexibility, the front leg test from a standing position (MFLPSS) was used, and to assess dynamic balance, the standing balance test was used platforms where two variables were used to display the results; total antero-posterior distance traveled (PUT) and root mean square deviation (RMS). After the initial testing, a specific fatigue protocol was performed on the subjects, which consisted of 6 one-minute bouts with a one-minute break between them. In order to check the success of the protocol, we used a modified Borg scale to assess the workload, with points from 0 (fatigue is not present) to 10 (the greatest possible fatigue is present). The results of the modified Borg scale show the success of the protocol with an average score of 8,41 ± 0,76. The difference between the first and second measurements of the MAGKUS test shows us that there is a statistically significant decrease in results (t=-9,38, p=0,00). The difference between the first and second measurements of the MESSAR test also indicate a statistically significant decrease in results (t=7,88, p=0,00). On the other hand, the difference between the first and second measurements of the MFLPSS results indicates a statistically significant improvement in the results (t=-5,94, p=0,00). The results of the dynamic balance assessment test are presented through two variables, and both variables show a decrease in results that is not statistically significant; PUT (Z=0,64, p=0,52) and RMS (t=-1,45, p=0,17). By conducting research and analyzing the results, it was concluded that acute fatigue has a negative effect on all motor abilities, except for flexibility, which has a pozitive effect. The product of that is increased range of motion and reduced control of movement, which ultimately increases the risk of injury. Less
