COMPARISON OF THREE MOTION ANALYSIS PROGRAMS BASED ON THE SHOT PUT PERFORMANCE

The aim of the study was to compare the results obtained using the three programs: Vicon, OpenSim and AnyBody. The feasibility of the application and of the selection of one of the programs for further analysis of the sport technique was checked. In the experiment herewith, the torque and power as function of time in the joints of the lower limb during the last phase of shot put was computed. Examinations of the kinematic and kinetic parameters of analyzed movement were carried out using Vicon system and Kistler force plates. Three top level national competitors took part in the study. The differences between the torques and power were checked with a modified RMS index. The results obtained indicate that OpenSim program may be useful for further studies, and in particular in controlling and analyzing the neuromusculaskeletal system
