20.500.12556/RUL-181530 Morphological asymmetries and their relationship to judo-specific performance in youth judokas The purpose of this study was to examine morphological asymmetries in male youth judokas using an integrated assessment combining three-dimensional (3D) body scanning and bioelectrical impedance analysis (BIA), and to determine how these asymmetries relate to judo-specific performance. Twenty-seven competitive male youth judokas were evaluated for bilateral girth, segmental length, and lean mass asymmetries across upper- and lower-limb segments. The Absolute Asymmetry index, expressed as a percentage for individual body segments, and the average body symmetry across all variables were calculated, and associations with performance were assessed using the Special Judo Fitness Test (SJFT). Significant right-dominant asymmetries were found in elbow girth p < 0.001, forearm girth p < 0.001, thigh girth p = 0.028, and leg muscle mass p = 0.008. Upper-limb asymmetries were the primary contributors to total-body asymmetry, reflecting the unilateral gripping and rotational demands typical in judo. Only calf girth asymmetry was significantly associated with SJFT performance, with greater asymmetry linked to poorer outcomes, indicating a specific rather than general asymmetry–performance relationship (r = 0.405; p = 0.037). These findings underscore the importance of early detection of segment-specific asymmetries and suggest that rapid digital anthropometry is a practical tool for monitoring morphological development in youth judokas. Early targeted interventions may support balanced technical execution, enhance performance, and reduce the risk of uneven loading patterns as athletes progress to higher age categories and competition levels. sport combat sports SJFT symmetry development monitoring 3D body scanning specific performance šport borilni športi SJFT simetrija razvoj spremljanje 3D-skeniranje telesa specifična zmogljivost true false true Angleški jezik Slovenski jezik Članek v reviji 2026-04-10 08:18:28 2026-04-10 08:18:30 2026-04-17 14:21:30 0000-00-00 00:00:00 2026 0 0 11 str. iss. 2, art. 894 Vol. 16 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 796.8 2076-3417 10.3390/app16020894 266347267 applsci-16-00894.pdf applsci-16-00894.pdf 1 226063858882B734828BF2F299E65102 d315efd54e3175575b6ed452374271bb2fdd4d474a7d4752f644ce2c348129ad 57ef6e67-34a6-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=232090 https://www.mdpi.com/2076-3417/16/2/894 Dostop z geslom 1 e2dc094f-34a4-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=232089 Fakulteta za šport 0 0 0
