“…In order to fit in a given category, many athletes of combat sports modalities adopt weight loss [5][6][7][8] , making use of different methods and can refer to caloric restriction, hydric restriction, dehydration by saunas, running wearing clothes which decrease heat exchange with the environment, use of plastic outfits, use of diuretic, laxative and/or stimulating medication, as well as vomiting induction. These methods can cause decrease in physical performance, negatively affect the cognitive aspect, damage health and even cause death 6,9,10 . Many studies have tried to investigate the effects of the body mass reduction on performance [11][12][13][14][15] , the anthropometric alterations 8,12,15 , the humoral responses 7,16,17 , the cognitive effects 9 and physiological responses 11 , differentiating the reduction method into gradual and fast 18,19 .…”

Athletes from many sports that are categorized by body mass tend to reduce it to fit in lower categories. Such reduction can compromise the athlete's performance and health. In order to determine the most appropriate category, the body composition is highly relevant, especially to avoid excessive reduction. Thus, this study analyzed the morphological profile of Brazilian Jiu-Jitsu elite athletes. The sample was composed of 11 athletes, aged 25.8 ± 3.3 years, medalists in national and/or international competitions. The analysis was performed to determine the anthropometric body composition and somatotype. Body fat percentage from this population was 10.3 ± 2.6 % fat, a high percentage of muscle mass (61.3 ± 1.5 %), and predominant mesomorphic component (5.5 ± 1.0) was observed. The points of highest and lowest fat accumulation were respectively abdominal (15.7 ± 6.3 mm) and chest (6.8 ± 1.5 mm) regions. It can be concluded that athletes from this sport showed higher body mass during the preparatory period than in competitive conditions (4.4 ± 2.4 %); however, they showed low body fat, high muscle mass percentage and predominant mesomorphic component.
