코어운동이 엘리트 축구선수들의 하지밸런스와 운동기능 및 혈중젖산에 미치는 영향

Abstract

The purpose of this study was to examine the effect of lower extremity balance, exercise function, and blood lactate by performing core exercise on elite soccer players. The study subjects were 10 elite soccer players and 10 control groups. Subjects exercised 3 times a week for 8 weeks, and the following conclusions were drawn. In the lower extremity balance, the change in left unilateral clerk showed a statistically significant difference as the exercise group increased post-test than pre, and the control group decreased post-test and did not show statistically significant difference. There was a significant difference between the two groups. The change of the right unilateral clerk showed a statistically significant difference as the exercise group increased post-test than pre, and the control group decreased post-test and did not show statistically significant difference. There was no significant difference between the two groups in pre-test, but there was a significant difference post-test. Statistically significant difference appears increase post-test than pre. Changes in the unilateral clerk of the left and right extremities with the closed eyes were statistically significant as the exercise group increased post-test than pre, and the control group decreased post-test and did not show statistically significant differences. There was no significant difference between the two groups. Among the exercise functions, the change of left grip force, right grip force, and flexibility increased statistically from pre-to-post and showed statistically significant differences. The control group declined post-test and showed no statistically significant difference. There was no significant difference between the two groups. The change in lactic acid in the blood decreased post-test than pre and showed statistically significant difference, and the control group increased post-test and did not show statistically significant difference. There was no significant difference in pre-test between the two groups, but there was a significant difference in post-test. As a result of the above conclusion, it was found that core exercise had a positive effect on lower extremity balance, exercise function, and blood lactic acid, and lower extremity balance and blood lactic acid were more effective than those without core exercise. Core exercise will be effective not only for elite soccer players but also for various athletes, and it is thought that it will help athletes' physical balance, reduce fatigue, and improve performance.
