Many research projects that deal with the transformations of morphological characteristics have pointed out their extensive complexity, considering the fact that they are the result of genetic factors (endogenic influence) as well as factors pertaining to the environment (exogenic factors), where it is necessary to point out that the influence of genetic factors is not the same for all of the latent morphological dimensions. Òhe different positions of the biacromial and bicristal range in the latent and taxonomic structure of morphological characteristics that have contributed to the actualization of the problem of the relation between the first and second horizontal axis of the body, as well as their relations to the other components of morphological status. Taking that viewpoint, we defined the aim of this research to identify those morphological characteristics which are to the greatest extent related to the development of the horizontal axes. Using a sample of 130 athletes, handball players (N=70) and soccer players (N=60), aged 16 to 27, all of whom play in national leagues, and using a system of 21 anthropometric variables, we analyzed the relations between the first and second horizontal axis of the body, and their connection to the development of the remaining morphological characteristics. The first horizontal axis was defined as the biacromial range and the other as the bicristal range, while the remaining morphological characteristics were defined as the 19 standard measurements of longitudinal and transversal dimensionality, volume and body mass, and subcutaneous fatty tissue. When calculating the connection between the first and second horizontal axis and the remaining variables of the morphological system, we used the Pearson correlation coefficient. In addition, we calculated the dimorphism index for the biacromial and bicristal range as the point of the biserial correlation between the peripheral types of sport and every horizontal axis. It has been determined that in the case of handball players, it is possible to talk of biacromial and bicristal variants of an ectomesomorphic body type, while in the case of soccer players, of a biacromial variant of an ectomorphic type and a bicristal variant of an endomesomorphic body type. Both in the case of the biacromial and bicristal range, the dimorphism is pronounced among athletes who belong to different populations.
