本研究的目的是通过超声心动图来确定学龄游泳运动员左心室大小、质量指数和功能的差异。研究组由82名参加系统游泳训练至少6个月的游泳运动员组成，对照组由41名年龄、性别和体重相似的久坐儿童组成。研究组左室内径、室壁厚度、主动脉根部内径、左房内径、左室重量指数均显著大于正常儿童（P < 0.05）。但左室收缩功能（射血分数、短轴缩短分数）和左室充盈特性无差异（P > 0.05）。总之，在儿童游泳有一个显着的增加，左心室的尺寸，壁厚和质量指数，但没有差异的收缩功能和左心室的充盈特性。因此，耐力训练参与的信息是必要的，以解释定量超声心动图数据。
The purpose of this study was to determine the differences in the left ventricular dimensions, mass index and function in school-aged swimmers by echocardiography. The study group consisted of 82 swimmers who participated in a systematic swimming training for at least six months, and the control group consisted of 41 sedentary children of similar age, sex and weight. In the study group, left ventricular dimensions and wall thicknesses, aortic root and left atrium diameters, and left ventricle mass index were significantly greater than the normal children (p < 0.05). However, there was no difference in the left ventricular systolic function (ejection fraction, shortening fraction) or in the left ventricular filling characteristics (p > 0.05). In conclusion, in childhood swimmers there was a significant increase in left ventricular dimensions, wall thicknesses and mass index, but no differences in the systolic function and filling characteristics of the left ventricle. Thus, information on endurance training participation is necessary to interpret quantitative echocardiographic data.
