- Abstract
[Purpose] This study investigated the effects of transient aerobic exercise of various intensities on cerebral blood flow and attention. [Subjects] Thirty healthy men aged 20-30 years old. [Method] Participants were randomly assigned to groups that exercised on an ergometer bicycle at intensities of 20%, 40%, and 60% of maximal oxygen uptake, and a control group that did not exercise. Using near-infrared spectroscopy, cerebral blood flow was measured during exercise and participants performed the paced auditory serial addition task (PASAT) and psychomotor vigilance task (PVT) before and after exercise. [Result] Cerebral blood flow in the bilateral frontal lobe area was significantly increased in the 60% group compared with the control and 20% groups. The 40% group and 60% group answered significantly more PASAT questions correctly after the exercise. [Conclusion] These results suggest that transient aerobic exercise at 60% of maximal oxygen uptake enhances the cognitive function of healthy young adults by increasing cerebral blood flow in the frontal lobe area.
