This study aimed to apply hip adduction with bridge and bracing with bridge and use ultrasound imaging to determine how they affect abdominal muscle thickness.
The procedure and purpose of the study were explained to general adult men. A total of 30 people who voluntarily expressed their intention to participate and met the selection criteria were selected to participate in the study after signing the consent form.
In this study, ultrasound imaging equipment was used to measure the subject's abdominal muscles, such as external oblique muscles, internal oblique muscles, and transverse abdominis muscles. The study results showed significant changes in muscle thickness increase in all of the external oblique muscles, internal oblique muscles, and transverse abdominis muscles using normal bridge, hip adduction with bridge, and bracing with bridge (p < .00). Additionally, in the relative contribution rate of abdominal muscles, there was a significant difference in thickness changes of the external oblique muscle, internal oblique muscle, and transverse abdominis muscle using hip adduction with bridge and bracing with bridge (p < .00). This study showed that hip adduction with bridge and bracing with bridge significantly increased muscle thickness compared with the general normal bridge. Considering the modified bridge, this study confirmed that they can be effective in body stabilization training only by changing the base of support or applying the breathing method without additional equipment.
