[Purpose] The purpose of this study was to determine whether forced expiration is correlated with abdominal muscle thickness. [Subjects] Twenty-three healthy male volunteers participated in this study. [Methods] The peak expiratory flow (PEF) was obtained using a peak flow meter with subjects in the sitting position. The thicknesses of the right rectus abdominis, external oblique, internal oblique, and transverse abdominis muscles were measured using B-mode ultrasonography at the end of a relaxed expiration in the supine position. [Results] Among the abdominal muscles, only the thickness of the external oblique muscle displayed a significant correlation with PEF. [Conclusion] It appears that the thickness of the external oblique muscle might be associated with PEF during forced expiration.
[目的] 本研究旨在确定用力呼气是否与腹肌厚度相关。[对象] 23名健康男性志愿者参与了本研究。[方法] 让受试者坐位,使用峰值流量计测量呼气峰值流速(PEF)。受试者仰卧位,在呼气末放松状态下,使用B型超声测量右侧腹直肌、腹外斜肌、腹内斜肌和腹横肌的厚度。[结果] 在腹肌中,只有腹外斜肌的厚度与PEF显示出显著相关性。[结论] 看来在用力呼气过程中,腹外斜肌的厚度可能与PEF有关。
