IPAQ-SF, International Physical Activity Questionnaire-Short Form; PSQI, Pittsburg Sleep Quality Index; [oxy-Hb], oxyhemoglobin concentration (μ mol/L); [deoxy-Hb], deoxyhemoglobin concentration (μ mol/L); Hb-diff, difference between oxy and deoxyhemoglobin concentrations (μ mol/L); cog-DT, cognitive dual-task; mot-ST, single motor task. Spearman’s correlation test. Bold values with p < 0.05.
