test, whereas dynamic exercise at a lower or higher
intensity unchanged or improved cognitive function with a
less amount; (2) the Stroop test increased the Oxy-Hb of
the bilateral prefrontal cortices without altering the Deoxy-
Hb, suggesting increased regional cerebral blood flow; and
(3) the enhanced Oxy-Hb response to the Stroop test tended
to correlate with improvement of the cognitive function.
Taken together, it is likely that ergometer exercise at the
moderate intensity for 15 min may improve mental cognitive
function through augmented neural activity in the
prefrontal cortex.
