The aim of this study was to examine the associations of fitness and physical activity with academic achievement in children with overweight/obesity. A total of 106 (10.0 +/- 1.1y, 61 boys) children participated. The fitness components were assessed by field and laboratory-based tests. Physical activity was measured via accelerometry. The academic achievement was assessed by a standardised test and school-grades. Field-based cardiorespiratory fitness was associated with language skills (ss-standardised- ranging from 0.281 to 0.365, p amp;lt; 0.01). The field-based muscular strength was associated with grade point average, natural and social sciences, and foreign language (ss = 0.280-0.326, all p amp;lt;= 0.01). Speed-agility was associated with some language-related skills (ss = 0.325-0.393, all p amp;lt;= 0.01). The laboratory-based muscular strength also showed an association with mathematics skills (ss = 0.251-0.306, all p amp;lt;= 0.01). Physical activity did not show significant association with academic achievement (p amp;gt; 0.01). Overall, the significant associations observed for muscular strength and speed/agility were attenuated and disappeared in many cases after additional adjustments for body mass index and cardiorespiratory fitness, indicating that these associations are inter-dependent. Our study contributes by indicating that other fitness components apart from cardiorespiratory fitness, such as muscular strength and speed-agility, are positively associated with academic achievement. However, these associations appear to be dependent on body mass index and cardiorespiratory fitness., Funding Agencies|Fundacion Alicia Koplowitz; Spanish Ministry of Economy and Competitiveness [BES-2014-068829, DEP2013-47540]; Spanish Ministry of Education, Culture and Sport [FPU15/02645, FPU14/06837]; Strategic Research Area Health Care Science, Karolinska Institutet/Umea University; Junta de Andalucia, Consejeria de Conocimiento, Investigacion y UniversidadesJunta de Andalucia; University of Granada, Plan Propio de Investigacion 2016, Excellence actions: Units of Excellence, Unit of Excellence on Exercise and Health (UCEES); European Unions Horizon 2020 research and innovation programme [667302]; SAMID III network, RETICS [PN I+D+I 2017-2021]; ISCIII-Sub-Directorate General for Research Assessment and Promotion, the European Regional Development Fund (ERDF) [RD16/0022]; EXERNET Research Network on Exercise and Health in Special Populations [DEP200500046/ACTI]; Fondo Europeo de Desarrollo RegionalEuropean Union (EU) [DEP2013-47540]; Spanish Ministry of Science, Innovation and Universities [FJC2018-037925-I]
