| Outline of Final Research Achievements |
The objective of this study was to investigate the fastest swimming form for para-swimmer. First, an optimizing simulation was conducted for a swimmer with hemiplegia using mechanical simulator SWUM, which was developed by the principal investigator’s team. As a result, it was found that the obtained fastest form increased the swimming speed for 0.2 m/s or more. Next another similar optimizing simulation was conducted for a swimmer with unilateral transradial deficiency. It was found that the swimming speed increased for 7% due to the improvement of the motion of the deficient arm. In addition, the improvement of performance was realized for the humanoid swimmer robot, which was used to validate the simulated results.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は実際の身体障がいスイマーを対象とし，より泳速度を向上させる泳フォームを数理的に解明することを目的としており，水泳においてこのような試みは世界的に見てもまったく行われておらず，学術的見地からも非常に意義深いものである．また実際のパラリンピック出場選手を被験者とし，研究結果が選手およびコーチにフィードバックされてトレーニングに活かされている．その結果，選手のパフォーマンスが実際に向上すれば，社会的にも大変意義深いものとなる．
