The Effects of Bridge Exercise with One Hip Joint Adduction on Trunk Muscle Thickness

ABSTRACT

Purpose@#This study aimed to verify the effects of bridge exercise with resistance to one hip joint adductor muscle on the thickness of external and internal oblique abdominal muscles, transversus abdominis muscle, and erector spinae muscle. @*Methods@#The subjects were divided into two exercise groups 15 for Bridge Exercise Group (BEG) and 15 for One Hip joint Adduction Bridge Exercise Group (OHABEG). The study used an ultrasonic instrument to measure trunk muscle thickness. OHABEG performed a bridge exercise with one hip Joint adduction. BEG performed a bridge exercise without resistance. @*Results@#The external oblique abdominal, internal oblique abdominal, and the transversus abdominis muscles showed a significant increase by period and time in intra-group interactions (p0.05). The erector spinae muscle had a significant increase in each period (p0.05). @*Conclusion@#These results demonstrated that bridge exercise with one hip joint adduction had positive effects on trunk muscle thickness. These results confirm that a bridge exercise with one hip joint adduction has a positive effect on the muscle thickness of trunk, suggesting the possibility of using it as a rehabilitation treatment for a lumbar stabilization exercise and as a basic data.
