[Purpose] The purpose of this study was to compare the effects of bridge exercises applying the abdominal drawing-in method and modified wall squat exercises on deep abdominal muscle thickness and lumbar stability. [Subjects] A total of 30 subjects were equally divided into an experimental group and a control group. [Methods] The experimental group completed modified wall squat exercises, and the control group performed bridge exercises. Both did so for 30 minutes three times per week over a six-week period. Both groups' transversus abdominis (Tra), internal oblique (IO), and multifidus muscle thickness were measured using ultrasonography, while their static lumbar stability and dynamic lumbar stability were measured using a pressure biofeedback unit. [Results] A comparison of the pre-intervention and post-intervention measures of the experimental group and the control group was made; the Tra and IO thicknesses were significantly different in both groups. [Conclusion] The modified wall squat exercise and bridge exercise affected the thicknesses of the Tra and the IO muscles. While the bridge exercise requirs space and a mattress to lie on, the modified wall squat exercise can be conveniently performed anytime.
[目的]本研究旨在比较应用收腹法的桥式运动和改良壁式深蹲运动对腹深部肌肉厚度和腰椎稳定性的影响。[对象]总共30名受试者被平均分为实验组和对照组。[方法]实验组完成改良壁式深蹲运动，对照组进行桥式运动。两组均每周进行3次，每次30分钟，为期6周。使用超声测量两组的腹横肌（Tra）、腹内斜肌（IO）和多裂肌厚度，同时使用压力生物反馈装置测量其静态腰椎稳定性和动态腰椎稳定性。[结果]对实验组和对照组干预前和干预后的测量结果进行比较；两组的Tra和IO厚度均有显著差异。[结论]改良壁式深蹲运动和桥式运动影响了Tra和IO肌肉的厚度。虽然桥式运动需要空间和床垫来躺，但改良壁式深蹲运动可以在任何时候方便地进行。
