Distribution of Cerebral Blood Flow during Biofeedback Training

抄録

Near-infrared spectroscopy (NIRS) is less restrictive for examinees than other brain function imaging methods such as positron emission tomography or functional magnetic resonance imaging. In addition, fixation of the head and recumbence on a special device during measurement are unnecessary with NIRS. Biofeedback training (BFT) elucidates the importance of mental training, and monitors and encourages the learning of psycho-physiological control necessary for peak performance. Electromyography of examinees' rectus femoris muscles and nearinfrared spectroscopy were simultaneously conducted to investigate the relationship between BFT and local cerebral blood flow. The influence of a kicking motion on brain functioning was confirmed. These findings suggest that BFT is effective in activating working memory.
