The voluntary running activities were compared with those in age-matched rats without hyperbaric exposure. Furthermore, the properties of the slow soleus and fast plantaris muscle fibers and their spinal motoneurons were examined. The voluntary running activities of rats with or without hyperbaric exposure increased during development. However, the activities were higher in rats with hyperbaric exposure than in those without hyperbaric exposure. The oxidative enzyme activity of the soleus and plantaris muscle fibers and their motoneurons increased following hyperbaric exposure. It is concluded that hyperbaric exposure with high oxygen concentration used in this study enhances the oxidative metabolism and thus the function of neuromuscular units is promoted., 資料番号: AA0063349067}, pages = {246--247}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {高気圧・高濃度酸素への曝露がラットの神経筋単位と運動能力に及ぼす影響}, year = {2007} }
