a) Change in prefrontal cerebral oxygenation (∆HbO2) F (1,19) = 4.5, p = .047, η² = 0.191 between single motor (SM) and dual task (DT). There was a significant decrease in PFC activation during the dual versus single task (p = .047). b) Change in prefrontal cerebral deoxygenation (∆HbR) F (1, 19) = 4.8, p = .040, η² = 0.203 between single motor (SM) and dual‐task (DT) blocks. Cerebral deoxygenation in the PFC significantly decreased between single and dual tasks (p = .040). (*) indicates significance p < .05. Error bars represent standard error of the mean
