Penning A, et al. – Researchers sought to determine the acute impacts of a simulated school day with reduced sitting or usual sitting on adolescents’ cognitive function and cardiometabolic biomarkers. Significant improvements in apoB/apoA–1 ratio with medium effect sizes for total cholesterol, HDL cholesterol and total cholesterol/HDL ratio were the reported consequences of attenuating school day sitting time in adolescents. Additionally, cognitive function outcomes demonstrated the equivalent of a 6–month improvement in effective mental–attentional capacity.
