The human numeric models can play an important role in Ergonomics. The simulation of an interaction between the operator/user and its environment/product can facilitate in great measure the analysis and the ergonomic evaluation accomplished by the ergonomist. However, the present models still present gaps and limitations resulting from the lack of knowledge of the human basic characteristics, namely the movement strategy and the discomfort laws. In this sense, the main objective of this study was to contribute for the enrichment of the available knowledge in these two areas, to indue the numeric human models of even more realistic postures. In the first place, regarding the comfort modeling criterions of the human operator, it was analyzed the discomfort level associated to each final posture found in the reach movement to a point. In the second place, at the level of the human functional capacities, regarding the cinematic redundancy of the superior member modeling, the objective was centered in the identification of the reach strategies, essentially in the trunk/superior member cooperation.
