20.500.12556/RUL-136748 Monitoring of eccentric hamstring strength and eccentric derived strength ratios in judokas from a single weight category Background: This study was designed to perform isokinetic knee testing of male judokas competing in the under 73 kg category. The main aims were: to establish the concentric (CON) and eccentric (ECC) strength profile of hamstrings (H) and CON profile of quadriceps (Q) muscles; to evaluate the differences in CON and ECC peak torques (PT) with various strength ratios and their bilateral asymmetries; the calculation of the dynamic control ratio (DCR) and H ECC to CON ratio (HEC); Methods: 12 judokas competing on a national and international levels with a mean age of 19 ± 4 years, a weight of 75 ± 2 kg and with a height of 176 ± 5 cm were tested. All the subjects were right-hand dominant. Isokinetic testing was performed on iMOMENT, SMM isokinetic machine (SMM, Maribor, Slovenia). The paired t-test was used to determine the difference between paired variables. The level of significance was set at p ≤ 0.05; Results: Statistical differences between left (L) and right (R) Q PT (L 266; R 241 Nm), H ECC PT (L 145; R 169 Nm), HQR (L 0.54; R 0.63), DCR (L 0.55; R 0.70), HEC (L 1.02; R 1.14) and PTQ/BW (L 3.57; R 3.23 Nm/kg) were shown. Bilateral strength asymmetries in CON contraction of 13.52% ± 10.04 % for Q, 10.86% ± 7.67 % for H and 22.04% ± 12.13% for H ECC contraction were shown. Conclusions: This study reports the isokinetic strength values of judokas in the under 73 kg category, emphasising eccentric hamstring strength and eccentric derived strength ratios DCR and HEC. It was shown that asymmetries are better detected using eccentric testing and that the dominant leg in judokas had stronger eccentric hamstring strength resulting in higher DCR and HEC. sport judo strength ratios bilateral asymmetries dynamic control ratio hamstring eccentric to concentric ratio weight categories šport judo razmerja moči bilateralne asimetrije dinamično nadzorno razmerje ekscentrična mišična moč koncentrična mišična moč težnostne kategorije true false true Angleški jezik Slovenski jezik Članek v reviji 2022-05-19 10:32:03 2022-05-19 10:32:04 2022-09-15 04:14:17 0000-00-00 00:00:00 2022 0 0 10 str. iss. 1, art. 604 Vol. 19 Jan. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 796.853.23 1660-4601 10.3390/ijerph19010604 92195587 ijerph-19-00604-v2.pdf ijerph-19-00604-v2.pdf 1 3FB35B6A64DFDB45AE0D69FA36ADFC7D fcfeb510947347661d1ef33cd21a78e95daff54f4029f36189494c93358590a9 9bc5754f-d74e-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=156516 https://www.mdpi.com/1660-4601/19/1/604 0 2728400a-d74e-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=156515 Fakulteta za šport 0 0 0
