Abstract
In general, the enhanced electromyographic activities were involved in increased metabolism of those muscles. In this phenomena, percutaneous oxygen saturation, such as the oxygenated and deoxygenated hemoglobin, shows certain changes in muscle. It was expected that the changes in the percutaneous oxygen saturation represented the phasic pattern in ankle synergistic plantar flexor muscle group, soleus muscle and medial gastrocnemius muscle. However, there were no results about changes in the oxygen saturation pattern for its antagonistic muscle, tibialis anterior muscle. The purpose of this study was to clarify the relationships within the oxygen saturation between agonist and antagonist muscle relative to the EMG activities during upper and lower limb different motor tasks.
