Abstract:
Although there are a number of reported cases of increased cerebral blood flow during exercise, there are no reports on the relation between changes of blood flow during exercise and attentional function. The purpose of this study is to clarify the relation between changes of blood flow during exercise with AT intensity and attentional function, using near-infrared spectral analysis. The subjects were 10 healthy males. The research protocol was to conduct steady load exercise. We randomly conducted two invention trials: 1) an exercise/task trial in which a trail making test (TMT) was performed as an attentional assignment during steady load exercise, and 2) a rest/task trial in which TMT was performed during rest as a control. As a result, we observed the following: increase of oxy-Hb in the prefrontal cortex during AT exercise, the significant shortening of TMT during exercise from 69.1±10.2 seconds to63.2±7.2seconds, and, with further control, that the more oxy-Hb rises, the more TMT time is shortened. From these results, it is suggested that 10 minutes of exercise would improve attentional function, and furthermore, there is a possibility that increased cerebral blood flow may be involved with the improvement of attentional function.
