RESUMO:
Girls begin pubertal maturity earlier than boys in the same age range, and sexual hormones contribute in structural and functional brain changes differently between the sexes, which may substantially affect cognitive capacity in this time period. Even though there are evidences that cardiorespiratory fitness is positively related to executive function capacity in childhood (i.e., prepubescent children), the sex-specific relation during pubertal maturity is limited. Therefore, the aim of our study was to verify if the relationship between cardiorespiratory fitness, executive function and attention performance in schoolchildren aged 11‒16 is sex-especific. For this, 57 girls and 75 boys from a private school in the city of Natal, Rio Grande do Norte, Brasil, participated in our study. Each participant completed a progressive running test to determine peak oxygen consumption (VO2peak), computerized cognitive tests and questionnaires for daytime sleepiness as well as other factors that might influence physical and cognitive performance. 73.7% of girls and 72% of boys presented healthy levels of cardiorespiratory fitness. After adjusting for covariates, we found that a higher VO2peak was associated which better performance in cognitive flexibility in girls, which was assessed through categories completed (β = 0.174; 95% CI 0.035, 0.314; P = 0.015) and persistent errors (β = -0.710; 95% CI -1.265, -0.155; P = 0.013) in Berg’s card sorting test. However, in boys, a higher VO2peak was associated with better performance in planning and problem solving, assessed through planning time in the tower of London test (β = -105.7; 95% CI -206.9, -4.5; P = 0.041). In conclusion, the findings in our transversal study suggest that the relationship between cardiorespiratory fitness and executive function in school children aged 11‒16 years is specific to each sex. In a more specific manner, cardiorespiratory fitness is related to cognitive flexibility in girls, while it seems to be related to planning and problem solving in boys.
