摘要：This study aimed to verify the influence of the measures adopted to hold pandemy of covid-19 on physical activity (PA) levels of children and adolescents and; to verify differences among sex and ages. A fast review was carried out, with a search in journals available in the PubMed, Scopus and Web of Science databases, using the keywords: Children, Adolescents, Exercise, Physical Activity and Covid-19. From 449 identified studies, 17 were selected by the criterion of containing data referring to before and during social restrictions periods within the same study. Except for one article, the summary of the results indicates a decrease in PA levels during the pandemic period, with a significant influence of social isolation on children and adolescents, with a higher proportion for adolescents and females. Results are closer among countries from the same region than among continents, due to differences in the socio-cultural environment where young people live, incentivized by their relatives. From the public health point of view, there should be concern that if this pattern of behavior continues after the pandemic ends, it would further increase the risk of already existing problems, such as delays in motor development, overweight, obesity, cardiovascular disease, and diabetes in adulthood.
