The article presents the results of research that investigates the influence of the throwing technique and the training of the individual on the forensic evaluation of the weight throw. For the purposes of this work, a trained individual is considered to be a person who does sports at least three times a week and has participated in one of the prestigious competitions in the last two years (for example, national or world championships, or other important competitions for a given type of sport). To achieve the goal, three hypotheses were established. The contribution presents concrete kinematic values of throwing a stone of 0.5 kg and 1 kg. Trained individuals have been shown to perform significantly better than untrained individuals. It has proven itself with all variable parameters, i.e. with all types of litter and with both loads.
