We have examined the question of whether acute dynamic
exercise leads to increased neural activity in the prefrontal
cerebral cortex, which in turn may cause improvement of
the cognitive performance with the Stroop test. To this end,
the relationship between the cognitive function and the
changes in the cerebral oxygenation of the prefrontal cortex
was compared before and after dynamic exercise for a
period of 15 min. The major findings of this study are that:
(1) ergometer exercise at an intensity of 40 % EXmax was
able to significantly decrease the time score for the Stroop
