中长跑运动员运动心电图的研究

Study on Exercise Electrocardiogram(ECG) of Middle-long Distance Race Athletes

观察中长跑运动员蹬车运动前及运动过程中的心电图特征。采用SchillerAT - 10运动心电图机记录蹬车运动前和运动过程中的心电图变化 ,并进行分析。中长跑运动员运动前心电图表现有多种形式的电活动 ,运动心电图显示 ,随运动负荷的增加 ,心率逐渐上升 ,J点下降 ,J80 上升 ,STS坡度增加。结果表明 ,多年的运动训练能改善心血管活动 。

We used AT-10 recorder to record the ECG of 34 middle-long distance race athletes to study the characteristic of ECG before and during exercise test.Before exercise test, the athletes's ECG showed diverse forms of electrical activities.With gradually increasing the load,we found that HR,J 80and STS were ascending and placement of J point was descending on exercise ECG. The most changes of athletes's ECG were functional adaption.Professional training could improve cardiovascular function.However,the changes of athletes' ECG during exercise test should be different from pathologic changes.
