Research Abstract	This study investigated whether transcutaneous xenon light irradiation around the stellate ganglion (Xe-SGI) not only reduces muscle pain accompanying muscle strengthening training in the upper extremity (UE) but also improves efficacy of muscle strengthening training in the UE. Out of 32 healthy volunteers who were enrolled in this study, 16 volunteers received a combination of muscle strengthening training in the UE and Xe-SGI (Xe-group), and the other 16 received only muscle strengthening training in the UE (control group). As a result, the further reduction of muscle pain accompanying muscle strengthening training in the UE and improvement in efficacy of muscle strengthening training in the UE were observed in the Xe-group compared with the control group. These results suggest the usefulness of a combination of muscle strengthening training in the UE and Xe-SGI.
