Purpose : The purpose of this study was to investigate the effect of single limb stance exercise according to the support surface on dynamic balance ability and abdominal muscle thickness. Methods : We recruited 28 healthy subjects in this study. Subjects were assigned to 2 groups by matching method. The control group was 5 males and 9 females, and single limb stance exercise was performed on the stable support surface. The experimental group consisted of 6 males and 8 females, and trained to stand on the unstable support. During the single limb stance exercise, the dominant foot was set as the foot that appeared numerically through the exercise of the dynamic balance meter (Biorescue). Single limb stance exercise along the supporting surface was maintained for 15 seconds and then rested for 15 seconds. It was repeated 5 times. Particularly, the balance exercise on the unstable support surface was sufficiently practiced. Independent t test was performed for comparison between groups. Paired t test was performed to compare before and after each group. Results : There was no difference between the control group and the experimental group in the comparison of dynamic balance ability (p>.05). However, there were significant differences before and after exercise in both the control and experimental groups (p<.05). Similarly, in the comparison of abdominal muscle thickness, there was a significant difference within each group, especially internal oblique and transverse abdominis (p<.05), and no difference between groups (p>.05). Conclusion : Based on these results, although there was no difference between the groups, in the experimental group, numerical increase in dynamic balance ability and abdominal muscle thickness was confirmed. Therefore, single limb stance exercise on the unstable support surfaces activates core muscles and has a positive effect on dynamic balancing ability.
