Abstract
Effects of Kai-Gou(Air-Ball Handling), a Qi-Gong strategy, on the biofeedback training for enhancement of the electroencephalographic-α activity(EEG- a BF) were studied. Under the conditions employed, the Kai-gou group subjects who performed the actions of Kai-Gou during the intervals of the trials of EEG-α BF training tended to exhibit higher integrated % α/sec. Values than the controls who took rest simply during the periods. Furthermore, among the Kai-Gou group subjects, ones who succeeded by the actions of Kai-Gou to have a feeling of the presence of a real warm ball between their hands showed good records in the EEG- a BF training. On the other hand, the results of psychological examinations(tests of MPI and TEG egogram) revealed that good records in the EEG-α BF training were associated,in the Kai-Gou group subjects, with high scores in AC item of TEG egograms, but in the controls, with those in N item of MPI test. It was therefore suggested from these results that the effects of Kai-Gou are caused at least partly by the achievement of relaxation due to exploitation or improvement of the BF ability to enhance the EEG- a activity and that such positive effects on the BF ability occurs mainly in subjects who are effected easily by the implication or instruction of others.
