20.500.12556/RUL-134413 Asymmetries in the technique and ground reaction forces of elite alpine skiers influence their slalom perfermance Background: Although many of the movements of skiers are asymmetric, little is presently known about how such asymmetry influences performance. Here, our aim was to examine whether asymmetries in technique and the ground reaction forces associated with left and right turns influence the asymmetries in the performance of elite slalom skiers. Methods: As nine elite skiers completed a 20-gate slalom course, their three-dimensional full-body kinematics and ground reaction forces (GRF) were monitored with a global navigation satellite and inertial motion capture systems, in combination with pressure insoles. For multivariable regression models, 26 predictor skiing techniques and GRF variables and 8 predicted skiing performance variables were assessed, all of them determining asymmetries in terms of symmetry and Jaccard indices. Results: Asymmetries in instantaneous and sectional performance were found to have the largest predictor coefficients associated with asymmetries in shank angle and hip flexion of the outside leg. Asymmetry for turn radius had the largest predictor coefficients associated with asymmetries in shank angle and GRF on the entire outside foot. Conclusions: Although slalom skiers were found to move their bodies in a quite symmetrical fashion, asymmetry in their skiing technique and GRF influenced variables related to asymmetries in performance. biomechanics kinematics kinetics global navigation satellite system GPS IMU inertial motion capture pressure insoles ski racing biomehanika kinematika globalni navigacijski satelitski sistem vzajemna inercija gibanja tekmovalno smučanje pritiskovni vložki true false true Angleški jezik Slovenski jezik Članek v reviji 2022-01-13 16:16:40 2022-01-13 16:16:41 2022-09-13 03:55:00 0000-00-00 00:00:00 2020 0 0 16 str. iss. 20, art. 7288 Vol. 10 Oct. 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 338.48-52:796.6 2076-3417 10.3390/app10207288 33645315 RAZ_Supej_Matej_2020.pdf RAZ_Supej_Matej_2020.pdf 1 431505AF5738C7C8E5F175F0B0F11B32 ca0590e5e56834969c31f4e35c02fcfc06364efacde6c790c68c3d50df95935b 047d9e5f-7484-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=152854 https://www.mdpi.com/2076-3417/10/20/7288 1 a1572f42-7483-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=152853 Fakulteta za šport 0 0 0
