Each functional-a diagnostic procedure begins with morphological anthropometry. Measured anthropometric dimensions talk about the current morphological athletes status as a result of hereditary factors and adaptations to the impact of training and nutrition. Anthropometric measures in the diagnosis are used to determine body composition and constitution somatotype of athletes. Body composition means the relative representation of different constituent elements of human body weight (Houtkooper and Going, 1994). To day there are many methods used for quantitative analysis of the composition of the body. These were all anthropometric methods that are based on the application of generalized square equations, methods of bioelectrical impedance and underwater measurement method. In sport are of great importance information obtained by establishing the relationship between certain anthropometric dimensions. In order of that, as normative are used certain indexes and standards. The subject of this paper is the body composition of elite Serbian wrestlers. The aim of this study was to determine differences in body composition of the top wrestlers in relation to the wrestling category, on the basis of 21 anthropometric measures, at the beginning of the preparatory period. Sample consisted of 29 senior Serbian wrestlers, categorized into the national and international category. The subjects were an average of 174.25 ± 6.1 cm high, 74.52 ± 12.93 kg heavy. Multivariate analysis of variance (Manova) has found statistically significant differences between different categories of top wrestlers.
