New Anthropometric Data for Bulgarian Females and 3D Biomechanical Model Results for Inertial Parameters of the Upper and Lower Extremities

In the current article we do report anthropometric measurements of 107 Bulgarian women performed by our team, that complement the representative anthropological investigation (Yordanov et al., 2006) of 2855 Bulgarian females aged 30–40 years. Based on these data, we present an approach for evaluating the mass-inertial parameters of the thigh, shank, upper and lower arm via using 3D geometrical modelling. We model the segments with a geometrical body, called right elliptic stadium solid, having cross-sections of elliptic stadium. The comparison of our model results with data reported in literature shows that the suggested modelling is successful since it uses 3D bodies closer to the actual shape of the foreseen segments. The results obtained could be used for the design of systems and devices aimed to enhance the rehabilitation, to help disabled persons and in criminology to evaluate body fall problems, ergonomics, sports, robotics, computer simulations and other fields of research.
