AB - Purpose：The purpose of this study was to assess the effects of the trunk muscle activity on bridging exercise according to the knee joint angle. Methods：Twenty-five healthy adults volunteered to participate in this study. Subjects were required to complete following four bridging exercises; knee joint flexion 120°, 90°, 60°, 45°. Surface electromyography from selected trunk muscles was normalized to maximum voluntary isometric contraction. Muscle activity was measured by QEMG-4 system(LXM 3204, Laxtha Korea). A repeated measures of one-way ANOVA with post-hoc Bonferroni's correction was used to determine the influence of bridging exercise on muscle activity for each muscle and descriptive statistics was used to determine local/global muscle ratio. Results：The internal oblique of bridging exercises 120°, 90° showed significantly(p<.05). The erctor spinae of all bridging exercises showed significant excepted between 60° and 45°(p<.05). Median of internal oblique/rectus abdominis ratio of 120° was 4.41, 90° was 3.94, 60° was 3.58, 45° was 3.39. Median of internal oblique/external oblique ratio of 120°was 2.66, 90° was 2.43, 60° was 2.87, 45° was 2.64. Conclusion：Angular motion decreasing with knee joint flexion made erector spinae activation increase. on the other hand, as decreasing abdomen muscle activation, the more performing motor learning is required for abdomen muscle strength and co-contraction for the trunk stabilization
