기능적 발목관절 불안정성 축구선수의 신경근 훈련이 발목관절 기능 및 운동 수행능력에 미치는 영향

Abstract

This study attempted to investigate the functional ankle instability (FAI) of soccer players. In this study, twelve college soccer players were selected as subjects. Before the experiment, based on the ankle joint instability scale (AII, FAAM, idFAI), six subjects with FAI were divided into FAI experimental group, while the other six subjects without FAI were classified as control groups. Firstly, functional movement tests were performed on two groups of subjects, including dynamic balance ability, rear-foot angle and hopping. Then, the two groups of subjects performed neuromuscular training for up to six weeks. When the training was over, we performed the same functional movement tests on both groups. Finally, we analyzed and compared the indicators of the experimental group and the control group before and after the training. The detailed results are as follows: After six weeks of neuromuscular training, there was a tendency for the dorsiflexion of the ankle joint to increase as well as the varus of knee-joint during the drop landing. After six weeks of neuromuscular training, the dynamic stability forward extension of the CON group was increased and the ability of side hop and figure-of-8 hop was improved. After six weeks of neuromuscular training, it was confirmed that the forward extension and figure-of-8 hop in the dynamic stability of the CON group were significantly improved than the FAI group, although we did not point out the differences between the groups before training. These results will provide useful information about the design considered for rehabilitation or prevention of CAI for soccer players.
