Abstract
Purpose : This study investigated the effects of different types of plank exercise on abdominal muscle thickness in subjects with asymmetric pelvic anterior tilt.

Methods : Participants with a diagnosis of pelvic anterior tilt were divided into an experimental group (n=12) and a control group (n=13). The thicknesses of the transverse abdominis (TrA), internal oblique (IO), and external oblique (EO) muscles were measured using an ultrasound diagnostic apparatus. The data were analyzed using an SPSS (Ver. 21) program.

Results : In the experimental group, there was a significant difference in the thicknesses of the left and right muscles in the standing and elbow plank exercises (p<.05). All the muscle thicknesses increased significantly during the plank exercises(elbow plank, right-side plank, and left-side plank) as compared with those in the standing position (p<.05). In addition, the side-plank exercise resulted in significantly higher muscle thickness of the supported side (p<.01, p<.001).

Conclusion : These findings suggest that asymmetric exercise should be applied to the change of the left and right muscles of the abdominal when applying plank exercise according to pelvic anterior tilt.
