The purpose of the study is to get aknowledgments about psychophysiological changes on the addition of EMG biofeedback conditions and apparatus. EMG muti-biofeedback training (BFT) for eight healthy adults were practiced on 32 trials, which had 7. 5 sec muscle contraction of the biceps brachii with 10 sec rest, repeatedly. This experiment were composed from two kind of works of the pursuit tracking and compensative tracking. EMG activities were transformed to the sound and the light as the feedback information and were compared with the external command value to evaluate the performance of these trackings. Following results were presented such as : 1) Integrated error values were decreased and this performance was elevated with trials of BFT in the compensatory tracking better than in the pursuit tracking. 2) After BFT, muscle strength of the fore-arm flexion was appeared lower value of 20% than before BFT. The efficiency of muscular contraction might be improved toward the economical condition with BFT. 3) EMG Power Spectra in the following BFT were changed to the lower frequency band (5-45 Hz) and then these phenomena indicated that tonic motor units and slow-twitch muscle fibers were activiated to the excitatory level.
