Purpose : This study examines the effect of trunk stabilization program on the body balance, lung capacity, and muscular activity of the rectus abdominis and external oblique of healthy adults. Method : A survey was conducted for 20 students of K University located in the city of Y in Gyeongsangbuk-do Province of Korea. The trunk stabilization program consisted of a hollowing exercise, curl-up, bridging exercise, and birddog exercise. This was performed 14 times in total (7 times a week for two weeks). For analysis, good balance was used to measure both static and dynamic balancing ability. A peak flow meter was used to measure the maximum expiratory flow, and MP150 was used to measure muscular activity of the rectus abdominis and external oblique. Result : After the trunk stabilization program, the participants showed a difference in score and time taken to achieve static and dynamic balance, and muscular activity of the rectus abdominis and external oblique at a statistically significant level (p<0.05). However, no significant difference was observed in the left-to-right distance and front-to-back distance in a dynamic balance, and the lung capacity (p>0.05). Conclusion : The results showed that the trunk stabilization program was effective in enhancing both static and dynamic balancing ability and muscular activity. It also increased the lung capacity although the change was not at a statistically significant level.

Purpose: This study was conducted in an effort to determine the effects of various abdominal drawing-in maneuver (ADIM) on the thickness and length of the transversus abdominis (TrA) when using lumbar stabilization exercises on healthy adults. Methods: 72 healthy adults were divided into four groups of 18 subjects each, to which different ADIM methods were applied. 1) a simple ADIM exercise, 2) an ADIM with pressure bio-feedback units, 3) an ADIM exercise with sling, and 4) an ADIM exercise with sling and vibration. Changes in the thickness and sliding length of TrA were measured when ADIM was conducted in the supine position prior to exercise and again when beginning the exercises. Following exercise, changes in the thickness and sliding length of TrA were measured using the same methods. Differences in group measurements prior to and following exercise were compared using a one-way analysis of variance. A paired t-test was applied to compare the before and after differences within each group. Results: Differences in TrA thickness change revealed that the ADIM exercise with sling and vibration group showed a significant difference in measurements taken prior to and following exercise. Differences in TrA length change revealed that the ADIM exercise with sling and vibration group showed a significant difference in measurements taken prior to and following exercise. Conclusion: ADIM exercise with vibration stimulation conducted in the bridge posture while in a prone position using a sling can be recommended as an effective exercise to improve the function of lumbar TrA.
