Outline of Final Research Achievements |
The thrust movements both under and above water of nine top-level synchronized swimmers were analysed using 3D DLT method. Since the peak height index (peak height/body height) and the maximum vertical velocity of the body's centre of gravity were related significantly, it is necessary to increase the vertical velocity of the body's centre of gravity in order to increase the peak height. Swimmers with a high peak height index showed a shorter unroll time with a quick extension of the hips. In sculling, the arm's position was maintained near the surface of the water during the arms pull phase. The arm's position was closer to the water surface with a higher vertical velocity of the wrists during the arms turn. It was found that important techniques to improve peak height in thrust movement, are to unroll with a shorter time, and to not lower the arms at the beginning of thrust movement and to turn arms rapidly and catch the water closer to the surface with horizontal forearms.
