中文摘要：

为探索不同频次的有氧健身操对大学生身体机能的影响，在东北大学健美操课中进行课内外一体化教学实验研究，并监测学生中心血流动力学参数的变化，结果显示：实验组实验后心率、射血时间（ED）和心内膜下心肌活力率（SEVR）显著优于对照组；实验组自身前后心率有显著性降低；对照组学生实验前后SEVR显著性降低；无论是实验组还是对照组，运动使得增强指数、中心动脉压小幅度下降：血管弹性得到改善。

英文摘要：

The paper uses methods of internal and external integration of teaching are studied to monitor the hemodynamic parameters, in order to explore the effects of aerobic in different frequency on body function of college students in Northeastern University. The results showed that heart rate, ejection duration （ED） and subendocardium myocardial viability ratio （SEVR） of experiment group are better than that in control group. And heart rate of experiment group and SEVR of control group both decreased. The exercise can increase indexes, decrease the central aortic pressure, improving the arterial stiffness for the experimental group and the control group.
