摘　　要：采用MCA-3C心脏功能综合检测仪,观察男子中长跑运动员在功率自行车上进行递增负荷运动时心脏收缩时间间期各指标的变化,并与非运动员进行比较,从而对中长跑运动员的左心功能进行系统评价。结果发现:安静及递增负荷运动过程中中长跑运动员LVET和PEP相对较长;递增负荷运动过程中,中长跑运动员心脏功能表现出优于普通大学生的心脏功能水平。Applying MCA-3C Synthetic Tester of Cardiac Information, an observation were made on the changes of all the STI indexes in the Male Athletes of Middle-distance Race during the process of discontinuous increasing load, at the same time, make an analysis on the features of these changes with which compared that of non-athletes group in order to arrive an systematic evaluation on the left cardiac function of Middle-distance Race athletes. We find that the value of LVET and PEP is the relatively long index of middle-distance race athletes at rest time and the process of discontinuous increasing load. During the process of discontinuous increasing load, the cardiac function of athletes of middle-distance race are better than the cardiac function of non-athletes.
