All abdominal muscles, including the transverse abdominis (TrA), should be modulated to improve core stability. This study aimed to investigate easier and more effective core exercise methods by comparing thickness changes in the TrA, internal oblique (IO), external oblique (EO), and rectus abdominis (RA) muscles during the abdominal draw-in maneuver (ADIM) and maximum abdominal contraction maneuver (MACM). Thirty healthy subjects who participated in this study underwent ADIM and MACM three times in random order. We measured the abdominal muscle thickness during ADIM and MACM using ultrasonography and compared the changes in the thickness of TrA, IO, EO, and RA muscles using a paired -test. Significant differences were observed in the thicknesses of all the abdominal muscles between the ADIM and MACM groups ( < 0.05). The MACM immediately increased the thickness of the TrA ( < 0.001, effect size (ES) = 0.931), IO ( = 0.001, ES = 0.761), EO ( = 0.008, ES = 0.415), and RA ( < 0.001, ES = 0.767) muscles. These results suggest that MACM is useful for immediately increasing the thickness of TrA, IO, EO, and RA muscles and may contribute to the clinical effect of simultaneous contractions on the changes in abdominal muscle thickness.
所有腹部肌肉，包括腹横肌（TrA），都应进行调节以提高核心稳定性。本研究旨在通过比较腹部收缩动作（ADIM）和最大腹部收缩动作（MACM）过程中TrA、腹内斜肌（IO）、腹外斜肌（EO）和腹直肌（RA）的厚度变化，来探究更简便、有效的核心锻炼方法。参与本研究的30名健康受试者以随机顺序进行了3次ADIM和MACM。我们使用超声测量了ADIM和MACM过程中的腹部肌肉厚度，并使用配对检验比较了TrA、IO、EO和RA肌肉厚度的变化。ADIM组和MACM组所有腹部肌肉的厚度均存在显著差异（<0.05）。MACM立即增加了TrA（<0.001，效应量（ES）=0.931）、IO（=0.001，ES = 0.761）、EO（=0.008，ES = 0.415）和RA（<0.001，ES = 0.767）肌肉的厚度。这些结果表明，MACM有助于立即增加TrA、IO、EO和RA肌肉的厚度，并且可能有助于同时收缩对腹部肌肉厚度变化产生的临床效果。
