- Abstract
The study selected 320 school-age children in Henan, measured their screen-based sedentary behaviour and physical activity by the adolescent sedentary activity questionnaire and physical activity questionnaire respectively, and evaluated their cognitive flexibility by the more-odd shifting task to investigate the relationships between screen-based sedentary behaviour and cognitive flexibility and the mediating role of physical activity between them in school-age children. The results showed that: (1) The screen-based sedentary behaviour has a significant negative relation with cognitive flexibility; (2) The indirect effect of screen-based sedentary behaviour impacted the cognitive flexibility by physical activity was -0.0017 (95% CI: -0.0049, -0.0001), confirming that physical activity mediated partly the relationship between screen-based sedentary behaviour and cognitive flexibility; (3) There were significant group differences in the accuracy of both conditions. The cognitive flexibility of school-age children with high-level physical activity was significantly better than that of school-age children with low-level physical activity, and excessive screen-based sedentary behaviour have a more obvious negative impact on the cognitive flexibility of school-age children with low-level physical activity.
