유,무산소성 운동선수와 시신의 배곧은근 형태 분석 = Analysis on Morphology of The Rectus Abdominis Muscle of Aerobic, Anaerobic Type Athletes and Cadavers

다국어 초록 (Multilingual Abstract)

This study was performed in order analyze the structural characteristics of the gross structure of rectus abdominis muscle (RAM) and epigastric artery distribution of athletes and Korean cadavers. The length of RAM was reached at one-fifth relative to the height in both groups. No difference between aerobic type athletes (distance runners) and cadavers in the length of RAM, whereas was shorter in anaerobic type athletes (gymnasts, weight lifters, sprinters) than that of cadavers. Among the athletic group, the length of RAM in aerobic type athletes of distance runners was longer than anaerobic type athletes, likely gymnasts, sprinters, and weight-lifters. The width of RAM in the cadavers was narrower than athletes, and the width of RAM in athletes demonstrated a sport event-specific structure, which was that the width of upper, middle and lower parts of RAM was broader in aerobic type athletes, weight-lifters, and gymnasts, respectively. The characteristics of the pyramidalis muscle (PM) in both sex observed as irregular structure and no sexual difference was found in the length of PM. Type and number of the tendinous intersection (TI) were observed as three intersections of typeⅠ, four intersections of typeⅡ and two intersections of typeⅢ, but only few cases was revealed typeⅢ. A large proportion of aerobic type athletes was belong to typeⅡ, whereas typeⅠ was prevalent. The structural characteristics of TI can be divided as complete and symmetric or remnant and asymmetric types. Complete and symmetric type was mainly occurred in the first and second rows from xiphoid process on TI in both groups, but a large portion of asymmetric type was shown in the fourth row of TI. In case of fourth row of TI, complete type was appeared in anaerobic type athletes, but inversely remnant type was observed in aerobic type athletes and cadavers. Further, complete and symmetric type was prevalent in female in occasion of cadavers. No difference in the size of epigastric artery between sexes, but the right deep inferior epigastric artery was bigger than the left one. Number of the hilum of superior epigastric artery was highest in typeⅠ (inside of RAM) and followed in typeⅡ (middle of RAM). The type Ⅳ (two mouths type) and typeⅢ (outside of RAM) were only shown in male and female cadavers. The length of deep inferior epigastric artery was four centimeters and longer in male than female, and the right side was longer than the left one in both sexes.
