안쪽번짐과 가쪽번짐이란 발목을 $90^{\circ}$중립자세가 되게하고 발 안쪽면과 바깥쪽면으로 구부리는 것을 말한다. 안쪽번짐의 각은 $20{\sim}35^{\circ}$가 정상이고 가쪽번짐의 각은 $10{\sim}20^{\circ}$가 정상이다. 발의 안쪽번짐과 가쪽번짐의 각이 정상치에 미달하거나 고통을 호소하면 이상이 있는 것이다. 따라서 그에 알맞은 치료법도 제시한다.

Inversion and Eversion of the foot means that the ankle is in a $90^{\circ}$ neutral position and bends to the inside and outside of the foot, respectively. The angle of the inversion of the foot is extremely normal from 20 to 35 degrees, and the angle of the ankle is 10 to 20 degrees. If the angle of foot Inversion and Eversion are below normal values or accompanied by sore pain, there is a problem.

The aim of the present study was to compare the strength, balance, and flexibility across two age groups (older adults vs. young adults). The isokinetic muscle function, ankle ROM, trunk forward flexibility, stability, and antropometric data for the elderly and 46 university students were collected. The results indicated that male older adults possessed relatively low flexibility (2.97cm) among the groups and showed better stability in the right foot than in the left foot and $35^{\circ}$ of plantar flexion ROM, which was not in the normal range. Their peak strength at the knee joint was below 50% of their counterpart. They revealed a hamstring deficit of 18.55%, ankle eversion deficit of 23.08%, and ankle inversion deficit of 19.19%. The results indicated that female older adults possessed comparable flexibility compared to female young adults. The reciprocal muscle strength ratio of both knees was under 50%, and the deficit was 14.32% (extension) and 19.73% (flexion). The ankle plantar flexion peak torque was approximately 62% (left) and 73% (right) of WS's. The ankle dorsi flexion deficit was 25.05% and the plantar flexion was 26.86%. The eversion deficit was 19.97% and the inversion was 21.09%. These results will be significant in establishing an elderly fitness enhancement program and policy.

The purpose of this study was to analyze the effects of flossing band exercise on the range of motion and vertical jump for taekwondo demonstration athletes with ankle functional instability. The subjects of this study were 21 male Taekwondo Demonstration Team athletes enrolled at D University. They were divided into functional ankle instability group(FAIG, n=7), mild ankle instability group(MAIG, n=7), and ankle stability group(ASG, n=7). All groups performed a acute flossing band exercise program. The results of this study are as follows; dorsi flexion(p<.01), inversion(p<.01), eversion(p<.05) and vertical jump(p<.01) were significantly increased in the FAIG. Flossing band exercise of Taekwondo demonstration team with FAI increased joint range of motion and vertical jump. Therefore, it was confirmed that it could be an intervention that can improve performance and reduce the risk of ankle injury.
