摘　　要： 为了研究长期运动对心脏自主神经功能的影响,通过对20名体育学院男生和17名其他男大学生进行心肺功能测试,观察变时反应和心率衰减在运动过程中的变化。结果显示,运动组的变时反应指数显著高于对照组;两组的心率衰减无显著差异。提示,长期运动可增强心脏自主神经系统的调节能力,特别是增强交感神经的敏感性。 In order to study the effects of long-term exercising on the cardiac autonomic nervous system, the authors observed changes of chronotropic response and heart rate attenuation during exercising by testing the cardiac and pulmonary functions of 20 male students in a physical education institute and 17 other male college students, and revealed the following findings： the chronotropic response index of students in the exercising group is significantly higher than the same of students in the control group; there is no significant difference in heart rate attenuation be- tween students in the two groups, which indicate that long-term exercising can boost the regulating capacity of the cardiac autonomic nervous system, especially, enhance the sensitivity of sympathetic nerve.
