The techniques of the top eight placers in the men`s and women`s hammer throw at the 2009 World Championships in Athletics were studied to obtain the latest data and insight into the technical condition of the world`s current best throwers. Video recordings of the best attempt of each thrower were analysed using a three-dimensional kinematographic measurement method. If this was not possible due to recording problems - usually judges, photographers or others on the infield obstructing the view - the thrower`s second best attempt was analysed. A 14-segment body model with 20 body surface landmarks and a landmark for the hammer head, used in previous studies of the event, was the basis for analysis. Using this model, the release parameters (release velocity, angle of release, etc), spatial characteristics of the throwing movement and other data derived could be quantified. To give guidance for coaches and athletes preparing for future high-level competitions, the mean values of the group, the extent of distribution, as well as the standard deviation and range of variation of selected parameters were derived and compared with other parameters. In addition, the correlations between different parameters were quantified by calculation of correlation coefficients.
