An ultrasonic examination of muscles was carried out with the help of echo chamber "Aloka-280" and "Aloka-630" (Japan), transducers of 3.5 and 5 MHz. Under examination there were 15 sportsmen and a group of people not going in for sports, aged from 17 to 21 years. Morphometry of the white line, wide abdominal muscles on seven levels and of musculus rectus abdominis on five levels was performed. It was found that systematic physical exercises resulted in hypertrophy of muscles of the abdominal wall and enlargement of the white line width. The arrangement of wide muscles of the abdomen corresponding to the lateral margin of musculus rectus abdominis is symmetrical on the right and left in each group. At all the levels of scanning the internal oblique muscle of the abdomen was localized medial to the musculus rectus margin. In sportsmen such an arrangement relative to one another is better pronounced than in a control group from the 2nd to 5th levels. An analysis of histograms has shown that abdominal musculus rectus of sportsmen possesses less echogeneity and is more echo-homogeneous than the muscles of people not going in for sports. Thus, constant physical exercises cause not only enlargement of sizes of the abdominal wall muscles, but also leads to changes in topographic-anatomic interrelations of its structures.
借助日本的“Aloka - 280”和“Aloka - 630”型超声诊断仪以及3.5兆赫和5兆赫的探头对肌肉进行了超声检查。接受检查的有15名运动员和一组年龄在17至21岁之间不从事体育活动的人。对白线、腹部阔肌在七个层面以及腹直肌在五个层面进行了形态测量。结果发现，系统的体育锻炼导致腹壁肌肉肥大以及白线宽度增加。在每组中，对应于腹直肌外侧缘的腹部阔肌的排列在左右两侧是对称的。在所有扫描层面，腹内斜肌都位于腹直肌边缘的内侧。在运动员中，从第2至第5层面来看，这种相对排列比对照组更为明显。直方图分析表明，运动员的腹直肌比不从事体育活动的人的肌肉具有更低的回声性且回声更均匀。因此，持续的体育锻炼不仅会导致腹壁肌肉尺寸增大，还会引起其结构的地形解剖学相互关系的变化。
