| Outline of Final Research Achievements |
The aim of this research project was to elucidate the neural control involved in butterfly stroke swimming, to clarify the characteristics of skilled swimmers in terms of muscular coordination, and to obtain specific suggestions for effective coaching and training methods. We investigated the characteristics of neural control for skilled and unskilled swimmers during butterfly stroke swimming using the muscle synergy analysis method. The main result suggested that skilled swimmers may dare to down kick with independent synergies to produce effective acceleration by kicking. Based on this finding, it was suggested that training to perform appropriately timed kicks is important to perform butterfly stroke swimming like skilled swimmers.

| Academic Significance and Societal Importance of the Research Achievements |
本研究課題の学術的意義として，熟練者と非熟練者のバタフライ泳に関わる泳技能の違いについて，動作中の筋活動を単純に比較するだけでなく、近年発展してきた筋シナジー解析の手法を用いて「筋間の協調性」という新しい観点から比較することができた．また社会的意義として，本研究課題では上肢，体幹，下肢の全身のコーディネーションの関する知見が得られたため，我々の結果は全身運動である水泳技能の理解を深めることに貢献したと考えれらる．
