The bachelor thesis deals with 2D kinematic analysis of javelin throw. The analysis focused specifically on the javelin thrower Martin Konečný with a personal record of 73.27m. We analyzed the javelin technique using Kinovea.org software. We compared the results of the analysis with a few javelin throwers, namely Jakub Vadlejch, Magnus Kirt, Thomas Rӧhler, Tero Pitkӓmӓki and Andreas Thorkildsen. The best personal performances of athletes in special javelin throw tests were used in the work and all test results were compared with our proband. In the resume, we made an evaluation and provided the feedback to the athlete.
