The purpose of the research was to study the dichotomy of physical development of athletes in three-dimensional space: the morphological parameters concerning sagittal, frontal and transverse planes were determined. Weight-lifters of high qualification and the athletes with a sports rating participated in the experiments. With the increase of the level of sports skill the dichotomy (symmetry-asymmetry) of physical development of weight-lifters in three-dimensional space is formed ambiguously: concerning sagittal and transverse planes the asymmetry of morphological attributes decreases, concerning frontal one for the muscles of the bottom finitenesses it grows, and for top - it decreases. The approach offered by the authors allows to investigate not only the elementary connections and dependences of the dichotomy of physical development of a person, but also its ambiguous, multilateral structure.
