20.500.12556/RUL-184801 Povezanost izbranih spremenljivk moči, ravnotežja in tehnične izvedbe s hitrostjo in natančnostjo leta žoge v nogometu Correlation of selected variables of strength, balance and technical performance with speed and accuracy of ball flight in soccer Namena raziskave sta bila a) ugotoviti, ali so spremenljivke moči sprednjih stegenskih mišic ter ravnotežja pri enonožni stoji povezane s hitrostjo in natančnostjo leta žoge pri udarcu mirujoče žoge s sprednjim notranjim delom stopala (SNDS) poševno naprej in b) ali obstajajo razlike v tehnični izvedbi udarca med nogometaši, ki žogo udarijo hitreje ali natančneje, in nogometaši, ki žogo udarijo manj natančno oziroma hitro. V raziskavi je prostovoljno sodelovalo 16 nogometašev. V okviru meritev smo izvedli meritve telesne višine in mase, izokinetične moči iztegovalk kolena (največji navor (Mmax) in velikost prirastka navora (VPN)), meritve ravnotežja stoje na eni nogi ter meritve hitrosti in natančnosti letov žoge pri čim hitrejšem in čim natančnejšem udarcu žoge v tarčo. Tehnična izvedba udarca je bila posneta in ocenjena na podlagi predhodno določenih kriterijev uspešnosti. S Pearsonovim korelacijskim koeficientom smo na ravni enoodstotnega tveganja ugotovili srednjo povezanost med spremenljivko hitrost leta žoge in VPN pri iztegu kolena udarne noge pri 60 °/s (r = 0,63). Prav tako smo srednjo povezanost ugotovili med hitrostjo leta žoge in VPN pri iztegu kolena stojne noge pri 180 °/s (r = 0,60). Tehnična izvedba gibanja se med bolj in manj uspešnimi udarci žoge ni razlikovala. Na podlagi rezultatov sklepamo, da je za izboljšanje hitrosti leta žoge po udarcu s SNDS poševno naprej v proces treninga nogometašev priporočeno vključiti vadbo za največjo in hitro moč iztegovalk kolena. The aim of the thesis was a) to discover how strength of anterior thigh muscles and single leg balance effects speed and accuracy of ball flight in a soccer kick of stationary ball with front inside part of the foot and b) to discover if there are any differences in kicking technique between those soccer players, who kicks ball faster and with more accuracy and those, who kicks ball slower and more inaccurately. The research group included 16 soccer players. Our testing battery included measurements of body height and weight, knee extensors isokinetic strength measurements (maximal isokinetic torque and the size of growth of isokinetic torque (SGIT)), a single leg balance test, measurements of speed and accuracy of the ball flight with aim of kicking the ball as fast and as accurate as possible. Technical performance during soccer kicks was filmed and assessed in accordance with predetermined success criteria. With the use of Pearson's correlation coefficient at the level of 1% risk we found middle connections between dependent variable speed of the ball flight and SGIT for knee extensors of kicking leg at the speed of extension 60 °/s (r = 0,63). We also found the middle connection between dependent variable speed of ball flight and SGIT for knee extensors of standing leg at the speed of extension 180 °/s (r = 0,60). There was no difference in technical performance between those, who kicked the ball faster and with more accuracy and those, who kicked the ball slower and more inaccurately. To improve the speed of the ball after soccer kick with front inside part of the foot it is necessary to incorporate the maximal and explosive strength training of knee extensors into our training programme. šport nogomet hitra moč tehnična izvedba udarca sport football soccer power kicking technique true false true Slovenski jezik Angleški jezik Članek v reviji 2026-07-15 09:16:34 2026-07-15 09:16:36 2026-07-16 04:35:48 0000-00-00 00:00:00 2025 0 0 Str. 177-184 št. 3/4 Letn. 73 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 796.332 3024-0603 10.52165/sport.73.3-4.177-184 265291523 SPORT+3-4-25_177-184_Koncar.pdf SPORT+3-4-25_177-184_Koncar.pdf 1 759B2EDE23318FD973230A877297B210 4b3384cd107fc893f64a8b0b3ac9b891fb65d17e42f284c6eb3e19c2d56838ff ee72647c-802b-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=240098 https://journals.uni-lj.si/sport/article/view/22456 1 f13ec025-801c-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=240047 Fakulteta za šport Šport 0 0 0
