Abstract: The objective of this study was to determine the importance of 24-hour movement recommendations, which include levels of physical activity, screen time, and sleep hours, and their association with cognition and academic performance in children. Based on this, four specific objectives were defined: i) To analyze research trends through a bibliometric mapping of scientific production related to 24-hour movement guidelines, identifying temporal patterns of publication, collaboration networks between countries and institutions, and main thematic lines developed to date; ii) To examine the evolution and current state of research on compositional data analysis (CoDA) applied to 24-hour movement behavior, identifying the main authors, journals, organizations, and key concepts that have structured this field of knowledge; iii) To synthesize the available scientific evidence on the association between compliance with 24-hour movement behavior guidelines and cognitive parameters and academic performance in children and adolescents, through a systematic review of observational studies; and iv) To explore and compare, using three increasingly complex network analysis methods, the interrelationships between 24-hour movement components, physical fitness, cognition, academic performance, mental difficulties, and sociodemographic factors in children, to identify the most robust associations and potential intervention points. To address objective number 4, cross-sectional data were used from a sample of children between seven and eleven years old, from the early grades of a state public school in Porto Alegre-RS, selected by convenience criteria. The results revealed a pattern of complex but specific interrelationships between 24-hour movement components, physical fitness, and cognitive-academic parameters in children. The comparison between three methodologies of progressive complexity (simple correlation, partial correlation, and regularized partial correlation) allowed for the identification of the most robust associations, particularly highlighting the connection between motor agility and cognitive function, as well as between aerobic capacity and academic performance, which persisted even after controlling for multiple variables. Body mass index (BMI) and waist circumference emerged as central nodes in all networks, with strong connections to each other and to moderate-tovigorous physical activity (MVPA). This methodological progression demonstrated that, contrary to the notion that "everything is connected to everything," there are specific and fundamental relationships that could constitute efficient leverage points for interventions, suggesting that strategies focused on components such as motor agility or MVPA could simultaneously promote improvements in body composition and cognitive-academic performance during child development.
