[Purpose] The purpose of the present study was to analyze the correlations of the thicknesses of the transversus abdominis muscle (Tra) and the internal obliquus abdominis muscle (Io) with static lumbar stability (SLS), dynamic lumbar stability (DLS), and balance. [Subjects] The subjects of the present study were 40 female university students who had no physical defects or pain. [Methods] The thicknesses of Tra and Io muscles were measured using an ultrasonic imaging diagnostic unit. SLS and DLS were measured using a Pressure Biofeedback Unit (PBU), and Weight Distribution Indexes (WDI) and stability scores (SS) were measured using a balance measuring unit. [Results] As the thickness of the Tra increased, SLS, DLS, WDI, and SS improved. As SLS improved, DLS and WDI were also improved. [Conclusion] To improve lumbar stability and balance, training is needed in order to increase the muscle mass of the transversus abdominis muscle.
[目的] 本研究旨在分析腹横肌（Tra）和腹内斜肌（Io）厚度与静态腰椎稳定性（SLS）、动态腰椎稳定性（DLS）及平衡能力之间的相关性。[对象] 本研究对象为40名无身体缺陷或疼痛的女大学生。[方法] 使用超声成像诊断仪测量Tra和Io肌肉的厚度。使用压力生物反馈仪（PBU）测量SLS和DLS，使用平衡测量仪测量体重分布指数（WDI）和稳定性评分（SS）。[结果] 随着Tra厚度增加，SLS、DLS、WDI和SS均得到改善。随着SLS的改善，DLS和WDI也得到改善。[结论] 为提高腰椎稳定性和平衡能力，需要进行训练以增加腹横肌的肌肉量。
