Outline of Final Research Achievements

This study aimed to develop a new swimming education support system by assessing self-body recognition in an underwater environment, and then presenting a method for enhancing self-body recognition and its psychophysical and neuroscientific evidence. The main findings of this study are that (i) it is possible to assess the interoception in an underwater environment, (ii) although the interoception does not change in an underwater environment, it may increase after immersion, and (iii) there is a possibility that the self-body recognition may change depending on the body posture.
In the future, we will verify the self-body recognition in postures appropriate for swimming activities and develop a swimming education support system.

Academic Significance and Societal Importance of the Research Achievements

本研究において、座位条件では水中環境において内受容感覚が変化しないことが明らかとなった。これは特異的な環境での活動に即した場合にのみ、内受容感覚が変化し、自己身体認知が変化する可能性を示している。つまり、特異的な環境での運動実践においては、その身体姿勢を考慮した自己身体認知を高めることが重要であるといえる。
