This study aimed to identify what impact the thickness differences between the leftside and rightside transversus abdominis (TrA), internal obliquus (IO) and external obliquus (EO) have on balance ability in the abdominal drawing-in maneuver (ADIM) and resting postures. [Subjects and Methods] In this study, 41 young adults were asked to adopt a resting posture and to perform ADIM. The thicknesses of the abdominal muscles (TrA, IO, EO) were measured using ultrasound imaging, Then balance ability was measured, so that a comparative analysis could be carried out. [Results] According to the results, the thicknesses of TrA and IO very significantly increased when ADIM was performed. The changes in thickness of the muscles on the left and right sides showed no significant correlations with balance ability. [Conclusion] According to the study results, the difference in thickness between the left and right side muscles in a normal person is small (symmetric), and the differences in the thickness of TrA and IO on the left and right side reduced when the ADIM, which is a re-education method for abdominal muscles was performed. Therefore, we consider that the ADIM should be used in future clinical trials to induce symmetric contraction of the abdominal muscles. Also, the correlation results of muscle balance and body balance can be used as empirical data.
本研究旨在确定腹横肌（TrA）、腹内斜肌（IO）和腹外斜肌（EO）左右两侧厚度差异对收腹练习（ADIM）及静息姿势下平衡能力的影响。[对象与方法]本研究中，41名年轻人被要求采取静息姿势并进行收腹练习。使用超声成像测量腹部肌肉（TrA、IO、EO）的厚度，然后测量平衡能力，以便进行对比分析。[结果]结果显示，进行收腹练习时，TrA和IO的厚度显著增加。左右两侧肌肉厚度的变化与平衡能力无显著相关性。[结论]根据研究结果，正常人左右侧肌肉厚度差异较小（对称），当进行作为腹肌再训练方法的收腹练习时，TrA和IO左右侧的厚度差异减小。因此，我们认为未来临床试验中应采用收腹练习来诱导腹肌对称收缩。此外，肌肉平衡与身体平衡的相关结果可作为经验数据。
