PENAMBAHAN CORE STABILITY PADA STAR EXCURSION BALANCE EXERCISE LEBIH MENINGKATKAN KESEIMBANGAN DINAMIS DAN MENURUNKAN FUNGSIONAL ANKLE INSTABILITAS DARIPADA STAR EXCURSION BALANCE EXERCISE PADA BELA DIRI TAEKWONDO

Abstract

Background: taekwondo is a martial art that uses a lot of lower limbs especially ankle so that functional ankle instability (FAI) often occurs. FAI occurs due to postural control, dynamc balance, and muscle function. One of the exercises that could be used was star excursion balance exercise; however there are still deficiencies in postural control as a result of no activation of the core muscle for the formation of postural stabilization. Objective: To know the addition of core stability to star excursion balance exercise further increases dynamic balance and decreases ankle functional instability than star excursion balance exercise in taekwondo martial arts. Method: This study used a randomized pretest-posttest control group design, group I received star excursion balance exercise and group II received core stability and star excursion balance exercise. Functional ankle instability was measured using the cumberland ankle instability tool (CAIT) and dynamic balance uses the star excursion balance test (SEBT). This research was carried out three times a week for 6 weeks. Results: the increase in dynamic balance before training in group 1 was 86.4±6.3, after training it was 92.3±6.7, and in group 2 before training it was 86.2±6.1, after training was 96.7±7.9The decreased in Functional ankle instability before training in group 1 was 20.4±1.8, after training it was 23.4±2.1, and in group 2 before training it was 20.3±2.8, after training was 25.0±1.9. The comparison of dynamic balance in groups 1 and 2 is meaningful (p <0.05). The comparison of dynamic balance in groups 1 and 2 is meaningful (p <0.05). Conclusion: Adding core stability to star excursion balance exercise increases dynamic balance and decreases ankle functional instability than star excursion balance exercise in taekwondo martial arts.
