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 (p<0.05), while there was no significant difference in inter-group changes (p>0.05). The erector spinae muscle had a significant increase in each period (p<0.05) but no significant difference in time, intra-group interactions, and in inter-group changes (p>0.05).
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.
