RESUMO. O objetivo do estudo foi avaliar a variabilidade intra e inter-avaliadores de medidas antropométricas realizadas por três antropometristas considerados experientes mediante o cálculo dos erros técnicos de medida (ETM). Para esse fim, foi selecionada uma amostra de 21 voluntários (25,7 ± 7,5 anos), sendo 12 homens e 9 mulheres. Foram consideradas as medidas de peso corporal (kg), estatura (cm), circunferências (cm) do braço direito relaxado, abdômen, quadril e coxa, e da espessura das dobras cutâneas (mm) tricipital, subescapular, suprailíaca, abdômen, coxa e panturrilha medial. As medidas foram realizadas em 2 dias consecutivos, sempre no período da tarde, envolvendo os mesmos equipamentos e os mesmos voluntários. Os resultados apontaram a ocorrência de ETMs acima dos recomendados para aceitabilidade, tanto a variabilidade intra-avaliador como inter-avaliadores, sugerindo, portanto, a importância e a necessidade de treinamento específico dos antropometristas.Palavras-chave: medidas antropométricas, erro técnico de medida, precisão, intra-avaliador, interavaliadores.ABSTRACT. Intra-observer and inter-observers variability of anthropometric measures. The aim of this study was to evaluate the intra and inter-observer reliability in the anthropometric measures of three expert observers through the technical error of measure (TEM). For this end, 21 healthy volunteers (25.7 ± 7.5 years) took part in the study, being 12 males and 9 females. The following aspects were analyzed: body weigh (kg), stature (cm), circumferences (cm) of relaxed right arm, abdomen, hip and thigh, and skinfold thickness (mm) of triceps, subescapular, supra-iliac, abdomen, thigh and calf medial. The measures were made in 2 different days, always in the afternoon, with the same equipments and in the same volunteers. The results pointed the occurrence of TEMs out of the recommended patterns, in both intra-observer and inter-observers variability. This fact showed the importance and need of specific training of the observers.
