This paper focuses on analysis of human body measurements and movements – usage of laser scanning technologies for gaining measurements, movement amplitudes and biomechanical parameters in interaction within personal protective equipment (PPE). Analysis of the work postures and PPE were performed on 155 males who perform their duties in the Latvian National Armed Forces. In order to provide the comfort for individual wearers, it is essential to implement the body size correlations. The main premise is the availability of extensive and accurate information on the body measurements of certain populations or targets, as well as their distribution per body size groups or sizes. Acquisition of rapid and wide measurement data is now possible via the 3D scanning or contactless anthropometric data acquisition method. In addition to obtaining the measurements necessary for designing the clothes, the 3D technology also allows study different types of wearing habits, and the interactions between the human body and clothing layers, considering the body movement types and postures to be carried out during daily work processes, as well as the dynamics of these movements [1,2]. The right clothing and equipment is of vital importance to the survival and effectiveness of military personnel [3]. One of initial aspects is appearance and fit of uniforms and how the information necessary to ensure it can be obtained and processed using modern technologies [4]: by non-contact anthropometric methods (3D anthropometrical scanner Vitus Smart XXL® is used in the study), data processing automation systems, pattern making CAD/CAM systems, etc.
