In the monograph, the criminological and biomechanical aspects of selected movement actions are discussed in detail. The main attention is paid to the biomechanics of falling from a height and the effect of age on fall parameters. The second part describes the biomechanics of throwing a load from the point of view of selected internal aspects. The last part of the monograph is devoted to the manipulation of a lifeless body and the possibilities of computer simulation in forensic biomechanics as the equivalent of a forensic experiment. At the end of the monograph, selected case studies are presented, in which both the methods of the criminological experiment and computer simulation of movement were used.
