Effect of Support Surface Difference in Bridging Exercise on Thickness of Transverse Abdominis

Objective: It was intended to study the effect of support surface difference in bridging exercise on thickness of transverse abdominis. Method: Dividing 35 healthy adults in H University located in Gangwon-do to 2 groups in September, 2009, the thickness difference of musculus transverse abdominis between bridging exercise on a support surface using a sling and a fixed support surface was studied. In order to measure the thickness of musculus transverse abdominis, ultrasonic imaging was used. For comparison between the groups, independent samples t-test was performed. Results: It was found that thickness changes of the musculus transverse abdominis between groups were 0.35 ± 0.21 ㎝ in the sling surface bridging exercise group and 0.16 ± 0.14 ㎝ in the fixed surface group, so it was suggested that the muscle thickness of bridging exercise group on the sling surface was increased more significantly (p<.05). Conclusion: It is considered that the bridging exercise on the sling support surface shows further increased thickness of the fixed surface bridging exercise group and is more effective to musculoskeletal prevention or therapeutic intervention.
