Our objective of this research is a development of the method that can detect Electroencephalograph (EEG) of an athlete under exercising. If EEG under exercising can be measured, we can assess the mental condition of the athlete. However, it is said that if a subject moves his/her body, EEG of subject cannot be measured without artifact. Because, signal level of EEG is very small, and body movements cause the electric noise between a skin and an electrode. Therefore, usually, EEG is measured in the shield room, and a subject is required rest in bed while measurement. In this paper, we will discus about our new measuring method that can detect EEG under exercising by using Independent Component Analysis (ICA). In our method, true EEG that is included in measured EEG is estimated and extracted by ICA. Five normal subjects under exercising were tested with our method, and in all cases EEG without artifact was able to measured. So, we think our new method will be useful for the research of mental condition of the athlete.
