Physical fitness and its association with cognitive performance in Chilean schoolchildren: The Cogni?Action Project

This study aimed to establish the association and differences in a diversity of cognitive domains according cardiorespiratory fitness (CRF), muscular (MF), speed-agility (S-AF) level large sample Chilean schoolchildren. 1171 schoolchildren aged 10-14 years participated. CRF, MF, S-AF were assessed through ALPHA-fitness test battery. Cognition was evaluated NeuroCognitive Performance Test, which involved eight tests related four main domains: flexibility (CF), working memory (WM), inhibitory control (IC), intelligence (IN). Both global (multivariate) individual (univariate) analyses performed determine functioning low-, middle-, high-fitness level. The showed significant effect for F(16,940)  = 3.08, p ? .001 MF groups, F(16,953)  = 2.30, p = .002, but not S-AF, F(16,948)  = 1.37, p = .105. CRF shows seven tests, involving CF, WM, IC, IN domains, whereas five without with IN. SA-F only IC. Statistical found between low- middle/high-fitness groups middle- groups. At level, both seem be associated higher profile scholars; however, at an all components show favorable relationship some domine. Then, future developing strategies should consider components, prioritizing those low-fitness
