| Outline of Final Research Achievements |
Center of mass (CoM) velocity in swimming direction is not stable, but fluctuates. First, we demonstrated that decreasing swimming velocity during glide phase was related to the increasing swimming performance for elite male breaststroke swimmers. In contrast, it was cleared that the higher increased COM velocity obtained by kick movement was related to increasing swimming performance for elite female breaststroke swimmers. The female swimmers who showed high kick velocity were moved their foot outward during early kick movement. In contrast the female swimmers who showed low kick velocity moved their foot backward. These results suggest that the higher increased COM velocity obtained by kick movement would not be related to foot velocity, but foot angle for elite female swimmers. Finally, we investigated the CoM velocity estimation method, which were using the both hip velocity with simulated arm velocity correction.
