The purpose of this study is to conduct a kinematic analysis for the trek start motion using a new start deck, with high school swimming athletes as study subjects. The following was concluded through the study.
First, a total time of .71±.06 s was taken for the trek start motion with the P1 taking the longest time, followed by the P3 and P2.
Second, during the start motion, the horizontal displacement in CM(center of mass) was longest in P3(E3~E4), while vertical displacement was greatest in Event 3.
Third, during the trek start motion, the CM horizontal velocity was the highest at 4.41±.33 m/s in Event 4 for all directions, while the vertical velocity was highest at -3.07± 23 m/s in Event 4 in the downward direction.
Fourth, during the start motion, for both the hip joints and knee joints, the leg in the back was turned first.
Fifth, the moment of the lower limb segment during the start movement was highest in the leg in the back for Event 2 and 3.
In conclusion, during the start motion on the new deck, in order to improve performance, it is more advantageous to cut down the time taken in P1 and to appropriately select the location of the CM in Event 1. Since the moment of the leg in the back is expressed more than the leg in the front, exercises that can make the rotation angle of the hip joints and knee joints on the side of the leg in the back can be helpful.
