20.500.12556/RUL-187351 Importance of body symmetry to establish stand balance after drop jump Pomen skladnosti telesa za vzpostavitev ravnotežja v stoji po skoku The aim of the study was to determine if body symmetry influences the establishment of stand balance after a drop jump. Thirty-two healthy sports students with experience in artistic gymnastics participated in this study. The participants had an average age of 19.8 ± 1.4 years, height of 182.9 ± 6.8 cm and weight of 79.1 ± 8.1 kg. Morphological characteristics were assessed by measuring differences between the left and right sides in forearm girth, upper arm girth, calf girth, thigh girth, long shoulder height, lean mass of legs and lean mass of arms. The standing balance result was calculated based on factor scores obtained from nine measurements taken over 30 seconds after jumping from a 25 cm height platform. These measurements included three for normal stand, three for blind stand, and three for deaf stand. The data was collected using a pressure insoles system and by measuring the difference in ground reaction force between the left and right legs. Stepwise regression analysis revealed that 27% of the differences in leg load could be explained by differences in morphological characteristics between the left and right sides with two significant predictors: the difference in long shoulder height explaining 16% of the variance and the differences in arm lean mass explaining 11% of the variance. Both variables showed a negative relationship with the factor jump standing. It was observed that imbalances in body symmetry could increase the long-term risk of acute or chronic injuries. Namen raziskave je bil ugotoviti, ali skladnost telesa vpliva na vzpostavitev ravnotežja po skoku v globino v stoji na nogah. V raziskavi je sodelovalo 32 zdravih športnikov z izkušnjami v orodni telovadbi. Udeleženci so bili povprečno stari 19,8 ± 1,4 leta, visoki 182,9 ± 6,8 cm in težki 79,1 ± 8,1 kg. Telesne značilnosti so bile ocenjene z merjenjem razlik med levo in desno stranjo v obsegu podlakti, obsegu nadlahti, obsegu meč, obsegu stegen, višini ramen, pusti masi nog in pusti masi rok. Rezultat stoječega ravnotežja je bil izračunan na podlagi faktorskih rezultatov, pridobljenih iz devetih meritev, izvedenih v 30 sekundah po skoku s 25 cm visoke podlage. Te meritve so vključevale tri za normalno stojo, tri za stojo brez vidne zaznave in tri za stojo brez slušne zaznave. Podatki so bili zbrani s pomočjo sistema pritiskovnih stopalnih vložkov in z merjenjem razlike v reakcijski sili na tla med levo in desno nogo. Stopenjska regresijska analiza je pokazala, da je 27 % razlik v obremenitvi nog mogoče razložiti z razlikami v telesnih značilnostih med levo in desno stranjo z dvema pomembnima napovedovalcema: razliko v višini ramen, ki pojasnjuje 16 % spremenljivosti, in razlike v pusti masi rok, ki pojasnjuje 11 %. Obe spremenljivki sta pokazali negativno povezavo z izvedbo skoka iz stoje. Neravnovesja v telesni skladnosti povečajo dolgoročno tveganje za enkratne ali dolgotrajne poškodbe. sport gymnastics 3D scan balance body symmetry body posture jump pressure insole šport telovadba gimnastika 3D čitalec ravnotežje somernost telesa telesna drža skok tlačni vložek true false true Angleški jezik Slovenski jezik Članek v reviji 2026-09-10 10:51:07 2026-09-10 10:51:09 2026-09-12 04:29:05 0000-00-00 00:00:00 2024 0 0 Str. 197-209, 368 iss. 2 Vol. 16 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 796.41 1855-7171 10.52165/sgj.16.2.197-209 200924675 197_Kascek.pdf 197_Kascek.pdf 1 DD8F1A1F3616976E86BBAEE2DE12E9E1 a94f5f2fba8623b0dc93fcdf02b2cc516224de90ee3597fbed0536074a4578f5 fb790c43-adb6-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=247230 https://journals.uni-lj.si/sgj/article/view/14846 0 b17c1781-acf5-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=246964 Fakulteta za šport Science of gymnastics journal 0 0 0
