본 연구는 무릎 관절 각도를 달리한 교각운동이 정적균형과 동적균형에 미치는 영향을 알아보기 위하여 용인시 소재 O병원과 Y대학교에 재직, 재학 중인 건강한 직원과 학생 54명을 선정하여, 18명씩 3개의 그룹(60°, 90°, 120°)으로 나누어 주 5회 2주 동안 진행하였다. 정적균형 중 EO(Eye Open) C90A는 60°, 90°, EC(Eye Close) C90A는 60°, 90°, 120°, EO TL은 60°, 90°, EC TL은 60°, 90°, 120°에서 운동 전, 후에 유의한 차이가 있었으며(p<.05) 각도 사이에는 유의한 차이가 없었다. 동적균형은 전 방향에서 운동 전, 후와 각도 사이에 유의한 차이가 있었다(p<.05). 위의 결과로 보아, 교각운동은 60°, 90°, 120°에서 운동 전, 후에 모두 효과가 있었지만, 90°에서 시행하는 것이 가장 유의한 차이가 있었음을 알 수 있었다.
The purpose of this study is to examine the effects of bridging exercises performed with different knee-joint angles on static and dynamic balance between before and after the exercises; it ultimately looks to present more effective bridging exercise methods. A total of 54 staff members and students at Yongin-si’s Y University, respectively, were selected as the subjects of this study. The subjects were divided into three knee-joint angle groups of 18 members each (60°, 90°, 120°), and both static balance After being measured before the exercise, the values were remeasured after the subjects performed bridging exercises five times repeatedly for 10 s each, five times a week for two weeks, at the various individual angles. The results of the study are as follows. Among static balance items, EO C90A showed significant differences between before and after the exercises at 60° and 90°; EC C90A showed significant differences at 60°, 90°, and 120°; EO TL showed significant differences at 60° and 90°; and EC TL showed significant differences at 60°, 90°, and 120°(p < 0.05). However, there were no significant differences among the angles. Among dynamic balance items, the forward direction showed significant differences between before and after the exercises, as well as among the various angles (p < 0.05).
