概要	This study aimed to clarify the electromyographic activity of all abdominal muscles during abdominal bracing using the latter method of activating the abdominal muscles while inflating the lower abdomen. Thirteen healthy men participated in this study. Transversus abdominis (TrA), internal oblique (IO), external oblique (EO), and rectus abdominis (RA) electromyography was recorded using an intramuscular fine wire and surface electrodes. The participants performed abdominal bracing and hollowing for 5 s in six different positions. In TrA electromyography, there was no difference between abdominal bracing and hollowing. On the other hand, the activities during abdominal hollowing were significantly higher than those during abdominal bracing in IO and EO. In RA, the activities during abdominal bracing were significantly higher than those during abdominal hollowing. Abdominal bracing under the method of inflating the lower abdomen is not recommended for high activity of the IO and EO
