在最大呼气期间，所有侧腹肌肉的收缩都比在腹部牵引动作（ADIM）期间更强烈。然而，很少有人知道，在最大呼气时，哪一个侧腹肌被激活。因此，本研究的目的是量化ADIM和最大呼气后即刻侧腹肌厚度的变化。采用超声成像技术测量30例健康男性在ADIM和最大呼气前后的腹横肌（TrA）、内斜肌（IO）和外斜肌（EO）厚度。ADIM后，侧腹肌厚度无明显变化。在最大呼气后，TrA肌肉的厚度显著增加，IO和EO肌肉的厚度没有显著变化。因此，最大呼气可能是一种有效的方法，而不是IO和EO，肌肉训练。(C)2012爱思唯尔有限公司保留所有权利。
All lateral abdominal muscles contract more strongly during maximum expiration than during the abdominal drawing-in maneuver (ADIM). However, little is known about which of the lateral abdominal muscles is activated during maximum expiration. Thus, the purpose of this study is to quantify changes in the thickness of the lateral abdominal muscles immediately after the ADIM and maximum expiration. The thickness of the transverse abdominis (TrA), internal oblique (IO), and external oblique (EO) muscles was measured by ultrasound imaging in 30 healthy men before and after the ADIM and maximum expiration. After the ADIM, there was no significant change in the thickness of the lateral abdominal muscles. After maximum expiration, the thickness of the TrA muscle significantly increased, and there was no significant change in the thickness of the IO and EO muscles. Thus, maximum expiration may be an effective method for TrA, rather than IO and EO, muscle training. (C) 2012 Elsevier Ltd. All rights reserved.
