Association between physical activity level of leisure and cognitive performance in healthy children

Abstract

The aim of this study was to assess the association of leisure physical activity on cognitive performance in healthy children. It was performed a cross-sectional study in which 100 children (10.8 ± 0.6 years of age) were divided into two groups as follows: "Insufficiently actives" (IA) and "Actives" (A). The cognitive performance was assessed by Memory and Learning of Figure Test, Stroop Test, Trail Making Test. It was observed a significant difference between groups for an incidental memory task from Memory and Learning of Figure Test (IA: 6.6 ± 1.4 versus A: 7.1 ± 1.2; p = 0.03). However, no significant differences were noted for any other variables. These findings reveal a positive influence of leisure physical activity on the incidental memory, but not long-term memory, mental flexibility, and inhibitory control in healthy children. Future studies with larger samples and direct measures of physical activity levels must be conducted to confirm these results.
