利用多普勒超声显示技术对10名举重运动员、10名摔跤运动员和10名健康人的右心室进行了研究，分别测量了受试者安静时的三尖瓣血流频谱、肺动脉血流频谱，结果发现，经专项训练的优秀举重、摔跤运动员的右心室心肌活动协调能力提高，举重、摔跤运动员的右心室收缩、舒张功能均优于对照组，但亦显示反映舒张功能的参数E峰加速时间、E峰减速度的变化和病理性心脏的变化相似，提示举重、摔跤运动员右心室的发展过程中可能存在生理性向病理性变化的潜在因素。同时，也提示了摔跤运动员对右心功能方面的变化优于举重运动员。本研究使我们能够进一步了解力量训练对运动员心脏功能的影响，并为力量项目运动员心脏的研究提供新的参数。
The right ventricle of 10 weightlifters, 10 wrestlers and 10 healthy people were studied by Doppler sonographic technique. The tricuspid blood flow spectrum, the pulmonary blood flow spectrum, The results showed that wrestling athletes’ right ventricular systolic and diastolic function were better than control group in weight-lifting and wrestling athletes, but also showed the parameters of E-peak acceleration time The change of E peak deceleration was similar to that of pathological heart, suggesting that there may exist some potential factors of pathological changes in right ventricle during the development of right ventricle in weightlifter and wrestler. At the same time, it also suggests that wrestlers have better right-heart function than weightlifters. This study allows us to further understand the impact of strength training on the heart function of athletes and to provide new parameters for the study of athletes’
