Abstract

SILVA, Paulo Rodrigo Pedroso da; TRINDADE, Rafael de Souza  and  DE ROSE, Eduardo Henrique. Body composition, somatotype and proporcionality of elite bodybuilders in Brazil. Rev Bras Med Esporte [online]. 2003, vol.9, n.6, pp. 403-407. ISSN 1517-8692.  http://dx.doi.org/10.1590/S1517-86922003000600005.

Bodybuilding is a sport that mainly emphasizes physical appearance, body configuration and shape, trying to achieve aesthetics perfection. Kinanthropometry is a fundamental tool to lead training follow-up in bodybuilding. In spite of that, there are few scientific papers on the subject. The purpose of this paper is to describe body composition, somatotype and proportionality of 23 bodybuilders in the 2000 Brazilian Bodybuilding Championship. The subjects were evaluated moments before the competition according to the following specific variables: total weight, stature, nine skinfolds (tricipital, subscapular, bicipital, chest, medium axillary, suprailiac, abdominal, front thigh, medium calf), muscle girths (flexed biceps and calf-standing), and three bone breadths (elbow, ankle and knee), in accordance with ISAK methodology. The athletes were between 20 and 56 years old, with body weight between 57.4 kg and 105.8 kg. The sum of the nine skinfolds varied between 38.4 mm and 70.2 mm. The somatotype was 1.8-8.1-0.7, which can be classified as a balanced mesomorphic one. The average of body fat was 9.65%, using the Faulkner protocol, proposed by the Brazilian Group of Kinanthropometry. Fat weight was 7.29 kg. When compared to Phantom, the athletes showed higher body weight (Z = + 1.66), elbow girth (Z = + 5.26), and calf girth (Z = + 1.91). This group of Brazilian elite bodybuilders showed lower body fat percentage and bigger muscular weight when compared to the Ross and Wilson model (1974), with their body structure similar to the elite international bodybuilders.
