RESUMEN
This paper aims to analyse studies and research conducted in EU and non-EU member states to identify and compare trends in physical activity and motor skills. Thus, a comparative overview of the state of the art in the two pre-pandemic decades that can facilitate an understanding of the different territorial realities and training needs to be conducted, considering the different cultural situations. A scoping review was conducted by analysing a series of studies published between 1990 and 2022, including only those studies that collected data in the pre-pandemic period. The search was carried out on databases such as PubMed, Google Scholar, and ScienceDirect. The following keywords were used for the acquisition of relevant studies: children, decline, motor skills, physical activity, and young people. From the literature review emerged clearly in all the longitudinal surveys a negative trend of body mass index (BMI), which was increasing in all the countries analysed, and cardiorespiratory fitness, which, in close relation to the increase in overweight levels, was in decline. If an unambiguous trend could be declared for the variables just mentioned, it was not possible to declare the same trend for the other variables analysed, which showed discordant results between the different countries.
