Abstract

I undertook a study that compared 10 students of tekwondo who were in their twenties. Half of which had experience in competitive environments and the other half not having competitive experience, the former would have better discipline in technique and the latter would show less. Jasebaqeo Pparun bal dollyuchagi motion would be performed in the testing. Comparing the two teams would present a difference that we can observe and measure.

The results are shown as followed

1. The time it took to compleat Jasebaqeo Pparun bal dollyuchagi.

The transition between movement (eg event 1 through to event 6) showed a slight difference however not so much that would have a significant impact.

2. The center of gravity performing Jasebaqeo Pparun bal dollyuchagi.

1) Observing the Left-Right (X axis) section E1 of the stance E1, the result of the less experienced subjects center of gravity was higher.

2) Forward and backwards (y axis) section E4 of the stance E4, the more experienced subjects results were higher.

3. The angle of the lower limb joints in Jasebaqeo Pparun bal dollyuchagi.

1) Section E2 shows that the difference in the angle of the left hip resulted in a notable difference in the more experienced subjects to be higher.

2) Section E5 shows that the angle of the right knee resulted in a notable difference in the more experienced subjects to be higher.

3) Section E5 shows that the angle of the left knee resulted in a notable difference in the more experienced subjects to be higher.

4) Section E6 shows that the angle of the right knee resulted in a notable difference in the less experienced subjects to be higher.

5) Section E4 shows the angle of the right ankle resulted in a notable difference in the less experienced subjects to be higher.

6) Section E6 shows the angle of the left ankle resulted in a notable difference in the more experienced subjects to be higher.
