目的：比较举重运动员与对照组的侧腹肌厚度。设计：病例对照研究设计。环境：大学实验室。对象：16名泰国女国家举重运动员和16名匹配的对照者参加了本研究。主要观察指标：采用12mhz线性阵列超声成像，测量右侧腹壁横腹肌（TrA）、内斜肌（IO）的静息厚度和外侧腹肌（LAM）的总厚度（total）。测定肌肉的绝对厚度和各肌肉对总厚度的相对贡献。结果：举重运动员TrA和IO绝对肌厚度显著高于对照组（p < 0.01）。此外，举重运动员的IO相对厚度显著大于对照组（p < 0.05）。结论：本研究的结果表明，在女性举重运动员中，常规的奥林匹克式举重训练似乎会导致内IO肌的优先肥大或适应性。(C) 2011 Elsevier Ltd.版权所有。
Objective: To compare lateral abdominal muscle thickness between weightlifters and matched controls.Design: A case control study design.Setting: University laboratory.Subjects: 16 female Thai national weightlifters and 16 matched controls participated in this study.Main outcome measures: Ultrasound imaging with a 12-MHz linear array was used to measure the resting thickness of transversus abdominis (TrA), internal oblique (IO) and total thickness (Total) of lateral abdominal muscle (LAM) on the right side of abdominal wall. The absolute muscle thickness and the relative contribution of each muscle to the total thickness were determined.Results: Weightlifters had significantly thicker absolute TrA and IO muscles than matched controls (p < 0.01). Further, the relative thickness of the IO was significantly greater in weightlifters than matched controls (p < 0.05).Conclusions: The findings of this study suggest that routine Olympic style weight training among female weightlifters appears to result in preferential hypertrophy or adaptation of the IO muscle.
