| Outline of Final Research Achievements |
The aim of this study was to clarify the relationship between breathing assistance(BA) and brain activity. The subjects were healthy adults and electroencephalogram (EEG) were measured with three respiratory conditions (normal breathing, BA, BA + deep breathing). We selected the average frequency of α wave power of the occipital region on the EEG, and the rest and mental task were repeated three times, and the correct answer rate of the mental arithmetic task were compared and examined. In addition, the brain fatigue sensation was measured by Visual Analogue Scale before and after the study. As a result, there was no change in the average frequency of α wave power in each respiration condition. The correct answer rate of the mental arithmetic task was significantly decreased in the second breath calculation from the first time in normal breathing. And furthermore, the brain fatigue feeling was high after the study in normal breathing and deep breathing combination with BA.
