The purpose of this study is to identify the time duration, position of center of mass and velocity, the angle of body segmentation and angular velocity, and analyze the surface reaction to understand how force is exerted and the physical segmentation movements happen. The findings were as follows.
First, the total time it took for the Forefoot dollyeo chagi was for experienced performers 0.29±0.02 s, and 0.31±0.01 s for inexperienced performers, with a significant difference.
Second, when performing a Forefoot dollyeo chagi, the position of center of mass on the left and right were both towards the right for experienced and inexperienced performers. In terms of front and back, the center of mass moved towards the front. In terms of vertical position of center of mass, there was a movement up wards but there was no significant difference.
Third, in terms of the foot velocity of the kicking feet, the velocity was highest at phase 3. There were significant differences in phase 3 and phase 4.
Fourth, the hip joint of the side of the kicking leg showed a curve in both experienced and inexperienced performers. The angle of the knee joint was curved up to phas3e but in phase 4 it was extended. The ankle joint of the kicking leg showed a low curve as the kicking progressed in experienced performers, but in inexperienced performers, dorsiflexion appeared upon impact, but with no significant difference.
Fifth, there was no significant difference in the angle velocity of the hip joint and the ankle joint for both experienced and inexperienced performers, but the angle velocity of the knee joint showed significant difference upon impact of the kicking leg and the supporting leg.
Sixth, there was no significant difference in the ground reactive force of left and right and vertical ground reactive force for experienced and inexperienced performers, but the front and back ground reaction force was big in phase 1 for experienced performers with significant difference.
The study’s findings indicate that in order to reduce the time it takes to perform a Forefoot dollyeo chagi, it is efficient to reduce the time during the preparation stage. To do this, training to make the segmentation movements from the close location to the far location would be needed. In addition, during the early phases of the kicking, the segmentation of the hip and a quick curving of the trunk would be more favorable for quick movements. Therefore, the fast angle velocity of the hip joint during the preparation phase can be seen as an important factor to perform a quick kick.
