20.500.12556/RUL-133822 Application of inertial motion unit-based kinematics to assess the effect of boot modifications on ski jump landings a methodological study Biomechanical studies of winter sports are challenging due to environmental conditions which cannot be mimicked in a laboratory. In this study, a methodological approach was developed merging 2D video recordings with sensor-based motion capture to investigate ski jump landings. A reference measurement was carried out in a laboratory, and subsequently, the method was exemplified in a field study by assessing the effect of a ski boot modification on landing kinematics. Landings of four expert skiers were filmed under field conditions in the jump plane, and full body kinematics were measured with an inertial motion unit (IMU) -based motion capture suit. This exemplary study revealed that the combination of video and IMU data is viable. However, only one skier was able to make use of the added boot flexibility, likely due to an extended training time with the modified boot. In this case, maximum knee flexion changed by 36° and maximum ankle flexion by 13°, whereas the other three skiers changed only marginally. The results confirm that 2D video merged with IMU data are suitable for jump analyses in winter sports, and that the modified boot will allow for alterations in landing technique provided that enough time for training is given. skiing kinematics motion analysis footwear measurement systems ski jump landing smučanje kinematika analiza gibanja smučarski čevlji meritve smučarski skoki doskok true false true Angleški jezik Slovenski jezik Članek v reviji 2021-12-16 12:13:43 2021-12-16 12:13:43 2022-09-13 03:52:44 0000-00-00 00:00:00 2020 0 0 9 str. iss. 13, art. 3805 Vol. 20 July 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 796.925 1424-8220 10.3390/s20133805 22045187 RAZ_Kurpiers_Nico_2020.pdf RAZ_Kurpiers_Nico_2020.pdf 1 E5022F39183FA6F39083BD9F281EB1B8 dba64ab47a5c66a9a14bd4b305a62a145627587128ff570d394ce26beee37e2d 4579cad0-5e61-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=152184 https://www.mdpi.com/1424-8220/20/13/3805 1 1a732a18-5e61-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=152183 Fakulteta za šport 0 0 0
