The purpose of this study was to comparative analyze the kinematic factors track start movement of female high school swimmers. Conclusions are as follows.
First, the average total time was short track start operation is excellent players. However, significant differences were not. Second, horizontal COM(center of mass) position from the track start operation has moved far away to have excellent players. And it showed significant differences in the E4 (p<.05). And vertical COM position was all excellent players and non excellent players move in a downward direction. And a significant difference was found. Third, the tracks start operation in horizontal COM velocity showed a significant difference in the E1 and E4 (p<.05). And it showed that excellent players fast. And vertical COM velocity was not a significant difference between excellent players and non excellent players. Fourth, the angle of the lower body joints in the track start operation showed right and left hip joint and knee joint extension of excellent players of this P2 significantly. And the hip joint of the left leg showed a significant difference between the E1 and E2 (p<.05), the knee joint angle did not show significant differences. Fifth, the angular velocity of the hip joint from the track start operation faster mean angular velocity of excellent players. However, a significant difference was found. And the angular velocity of the knee showed a significant difference in the E1 and E3 of the right leg (p<.05). Sixth, there was no significant difference in angular momentum between the excellent players and the non excellent players during the swimming track start. The angular momentum of the excellent players showed larger angular momentum than that of the non excellent players.
Taken together, the above results were excellent players effectively use both the front left leg of the back legs, the movement of these are not considered a factor that acts as a quick get away to increase the horizontal CM velocity.
