The purpose of this study is to investigate the effect of the long-term aerobic exercises on cardiac structure, left ventricular stroke volume, and cardiac output. To achieve the purpose of the study, a total of 22 volunteers-including 10 people who have continued regular exercises and 12 people as the control group-were selected as subjects. With regard to data processing, the IBM SPSS Statistics ver. 21.0 was used to calculate the mean and standard deviation, and the difference of the means between the groups was verified through an independent t-test. As a result, there were significant differences between groups in the left ventricular end-diastolic internal dimension, left ventricular end-systolic internal dimension, left ventricular end-diastolic septum thickness. There were significant differences between groups in left ventricular end-diastolic volume, left ventricular mass, and left ventricular mass index per body surface area. However, in cardiac function, only left ventricular stroke volume showed a significant difference between groups.
本研究的目的是调查长期有氧运动对心脏结构、左心室搏出量和心输出量的影响。为实现该研究目的，共选取了22名志愿者作为研究对象，其中包括10名持续进行规律运动的人和12名作为对照组的人。在数据处理方面，使用IBM SPSS Statistics ver. 21.0计算均值和标准差，并通过独立t检验验证组间均值差异。结果显示，在左心室舒张末期内径、左心室收缩末期内径、左心室舒张末期室间隔厚度方面，组间存在显著差异。在左心室舒张末期容积、左心室质量和每体表面积左心室质量指数方面，组间也存在显著差异。然而，在心脏功能方面，只有左心室搏出量在组间显示出显著差异。
