Zusammenfassung:The main purpose of this review was to accost conceptual and operational issues associated with physical activity patterns (PAF) in children and adolescents. A systematic research was done in national and international data bases in order to select recent studies with information concerning PAF. There are different ways to describe and quantify PAF using univariate and mukivariate statistical techniques. Most of studies identified that physical activity is characterized by extremely short periods of high intensity, with a predominance of moderate to low intensity activity. On weekends these periods are longer and boys have higher frequencies of episodes in different levels of intensity. "Physical activity pattern" is a usual expression, but there is no unanimous concept and interpretation. Using a multimode approach would certainly improve our understanding of PAF, considering its type, frequency, duration, and intensity.Original Abstract: O objetivo principal desta revisao foi abordar aspectos conceituais, operacionais e apresentar os principals resultados relativos ao padrao de atividade fisica (PAF) em criancas e jovens. Foi realizada uma pesquisa era bases de dados nacionais e internacionais com intuito de selecionar estudos originais recentes que apresentassem infortnacoes acerca do PAF. A maioria das pesquisas apresentam maneiras distintas de conceituar e operacionalizar o PAF, utilizando tecnicas estatisticas univariadas e multivariadas. Grande parte dos estudos identificou que a atividade fisica na infancia se caracteriza por periodos extremamente curtos de alta intensidade, com predominio de atividades de moderada a baixa intensidade. Durante os finais de semana, esses periodos sao maiores e os meninos apresentam uma maior frequencia de episodios de niveis distintos de intensidade. A expressao "padrao de atividade fisica" e comumente utilizada, porem nao e encontrada uma interpretacao e conceitualizacao unanime. A adocao de analise multimodal seria uma mais valia, uma vez que podera auxiliar o entendimento das nuances da atividade fisica, considerando o seu tipo, frequencia, duracao e intensidade.
