A new procedure of muscle strengthening training using transcutaneous xenon light irradiation around the stellate ganglion.

本研究调查了星状神经节（Xe-SGI）周围的经皮氙光照射是否不仅减少了上肢（UE）肌肉强化训练伴随的肌肉疼痛，而且提高了UE肌肉强化训练的效果。在32名健康志愿者中，16名志愿者接受了UE和Xe-SGI的肌肉强化训练（Xe组），另16名志愿者仅接受了UE的肌肉强化训练（对照组）。结果，与对照组相比，Xe组中观察到UE中伴随肌肉强化训练的肌肉疼痛进一步减轻，UE中肌肉强化训练的功效提高。这些结果表明UE和Xe-SGI中肌肉强化训练的组合的有用性。

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.
