| Outline of Final Research Achievements |
We developed a new detection coil for phosphorus magnetic resonance spectroscopy that can measure the phosphorus compound content of deep tissues in the trunk, and investigated the optimal measurement program and conditions for data acquisition. As a result, we were able to build a measurement system that enables data collection in about 13 minutes. Next, using the developed system, we performed measurements on track and field sprinters and long-distance runners, and found that the relative content of phosphorus compounds in the psoas major muscle was different between them. As described above, the usefulness of the system developed in this study for evaluating the content of phosphorus compounds in the psoas major muscle was demonstrated, but it was suggested that further improvements are needed for more accurate quantitative evaluation.

| Academic Significance and Societal Importance of the Research Achievements |
本研究で開発した、磁気共鳴分光法を用いたリン酸化合物含有量測定システムにより、これまで測定困難であった大腰筋をはじめとした生体深部組織の特性、特にリン酸化合物含有量や細胞内pHに関する情報を収集することが可能となり、深部組織の質的特性やその適応に関する新たな学術的知見を得る上で有用になると考えられる。さらに、本システムは、スポーツ・健康科学分野における深部骨格筋特性の評価のみではなく、医学分野における深部の骨格筋やその他の軟部組織におけるエネルギー代謝の視点からの臨床診断において活用されることも期待できる。
