| Outline of Final Research Achievements |
In this study, we used in combination with 3D motion analysis and surface electromyography measurement for three kick movements in swimming (flutter kicking, dolphin kicking, and breaststroke kicking). As the results, it was shown that the standard motions in university male swimmers and the general muscle activity patterns during three kick movements. In addition, it was clarified that the swimmer increases swimming velocity with the increase in movement speed caused by the increase in muscle activity, and that the changes in propulsive force exerted in the foot were related to the changes in muscle activity.

| Academic Significance and Societal Importance of the Research Achievements |
水泳のキック動作は推進力に寄与していることが指摘されているものの，これまで詳細な動作分析が行われてこなかった．そのため，本研究で提示した3次元の標準動作と筋活動の平均波形は，各キック動作の指導法やトレーニング法を検討する上での基礎的かつ重要な資料になると考えられる．また，本研究の結果から，キック動作における筋活動，キネマティクス、推進力発揮の関係性が明らかになった．このことは，泳者が泳速度を増加させる際の適切なトレーニング戦略を立てる上で有益な知見になると考えられた．
