The purpose of this study was to elucidate the morphological characteristics of the lateral abdominal muscles of university athletes who participate in competitions that involve frequent torsional motion. The subjects were 16 male university athletes (athletic group; five from the baseball club, three from the canoe club, and eight from the tennis club) and 19ordinary university students (non-athletic group). The lateral abdominal muscles (external oblique muscle, internal oblique muscle, and transverse muscle) were measured for muscle thickness using B-mode ultrasonography. Comparison of the athletic and non-athletic groups revealed a significant difference in the external and internal oblique muscles, both of which were thicker in the athletic group compared to the non-athletic group. No significant difference was seen in the transverse muscle. The calculated effect size was significantly larger in the internal oblique muscle compared to the external oblique muscle. Marked development of the abdominal oblique muscles, especially the internal oblique muscle, was found to be a morphological characteristic of the lateral abdominal muscles of athletes who participate in competitions that mainly involve torsional motion.
