    Atletas de culturismo têm como alvo de treinamento a hipertrofia muscular e a redução da adiposidade. A falta de referências antropométricas apropriadas pode levar esses indivíduos a serem erroneamente considerados em situação de sobrepeso ou desnutrição. Portanto, objetivamos comparar a composição corporal de atletas de culturismo com os padrões populacionais. Foram avaliados 36 atletas, de ambos os sexos, 26 do sexo masculino (27,2 ± 7,2 anos) e 10 do sexo feminino (30,0 ± 6,1 anos), por ocasião da competição nacional, quanto aos indicadores antropométricos de peso, estatura, índice de massa corpórea, pregas cutâneas, adiposidade corpórea e circunferência muscular do braço. Os resultados foram referidos quanto à posição percentual ou de desvios-padrão (pelo escore Z) tendo como referências padrões populacionais locais. Como resultado, encontramos que os indicadores com menor contraste com os padrões adotados foram peso e estatura e os maiores contrastes foram encontrados na circunferência muscular do braço para os homens, e pregas cutâneas tricipital para as mulheres. Pelo indicador muscular todos foram classificados como obesos ou sobrepeso, enquanto que pela prega cutânea tricipital e adiposidade corpórea, a desnutrição esteve presente em 100,0% das mulheres e 88,5% dos homens. Fica evidenciada a inadequação da utilização do padrão antropométrico populacional para a classificação nutricional de atletas de força, em particular culturistas, sendo assim necessário o estabelecimento de padrões próprios para esse tipo de treinamento (modalidade).<br>Body builders have as their training goals the maximum muscle hypertrophy with minimum adiposity. However, the scarcity of specific standards implies often in framing wrongly those athletes either as overweight (by their BMI) or energy malnourished (by their fat stores). The objective of this study was to compare the body composition of body builders with population standards. Thirty-six adults, 26 male (27.2 ± 7.2 years) and 10 female (30 ± 6.1 years) nationwide competitive body builders, were assessed considering weight, height, body mass index, adiposity, arm and leg circumferences and skinfolds. The data were referred either as percentile or standard deviations (Z score) of population standards. Body weight and height were among the closest values from the populational mean whereas upper arm muscle circumference (for men) and body adiposity (for women) were the farterest. By using fat parameters as indicators of their protein-energy status, the undernourishment was found in 88.5% of men and 100.0% of women. Thus, it seems that body builders deserve their own anthropometric standards to avoid nutritional status misplacements

    Growing knowledge: an overview of Seed Plant diversity in Brazil

    Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora
