Kinematic model of start and crossing the hudrle of Croatian recorder on 100 meter hurdles

Cilj ovog diplomskog rada bio je utvrditi osnovne kinematičke pokazatelje starta, startnog ubrzanja i prelaska preko prve prepone hrvatske rekorderke u disciplini trčanja 100 metara s preponama. Utvrđivali su se podaci položaja težišta tijela (TT) kod starta, startnog ubrzanja te prelaska preko prve prepone, zatim duljine koraka, brzine TT-a, kutovi u zglobu koljena i kuka i još neki. Navedeni podatci su prikupljeni zbog toga što o njima uvelike ovisi rezultat utrke na 100 metara s preponama. Hrvatska rekorderka A.I. tada je imala 31. godinu i izvodila je navedene dijelove utrke, po tri puta iz startnog bloka na startni pucanj, te su podaci za ovaj rad uzeti iz najbrže izvedenih pokušaja. Prikupljeni podaci obrađeni su u APAS-u, a grafički prikazi izrađeni su u modulu APAS View i u programu Kineovea.The aim of the present thesis was to determine fundamental kinematic indicators of start, start acceleration and crossing the first hurdle of Croatian recorder in a discipline 100 meter hurdles. Determined were the positions of the center of gravity at start, start acceleration and crossing the first hudrle, then the length of the stride, the velocity of the center of gravity, the angles of the knee and hip, and others. These data were collected because the final result of a 100 meter hurdles race depends on them. Then the Croatian recorder A.I. had 31 years and performed the mentioned parts of the race, three times from the starting block on the start signal, and the data were taken from the fastest attempts. The collected data was processed in the APAS and the graphical views were made in the APAS View module and in the Kinovea program
