大学生长跑运动员心脏植物神经功能的观察

THE OBSERVATION OF THE FUNCTION OF CARDIOVASCULAR AUTONOMIC NERVOUS SYSTEM IN THE STUDENTS TAKING DISTANCE RUNNING

用无创伤方法观察我院冬季越野赛获男、女前十名的运动员与普遍学生的心脏植物神经功能。结果显示，男、女运动员反映心脏植物神经功能的各项指标均好于普通学生，其中平卧心率、呼吸差、３０／１５比值和乏氏指数有显著差异（Ｐ＜０．０１或Ｐ＜０．０５）。表明长跑锻炼可以增强学生心脏的植物神经功能。

The function of cardiovascular autonomic nervous system (FCANS)were studied with noninvasive method in the first ten place getters in Winters Cross country Race of our college.The other students,12 girls and 12 boys,were examined as controls.The results showed that the indices of FCANS in runners were all improved than those in controls,especially the indices of the heart rate in supine position (HR),the difference of HR between deep inspiration and expiration (DHRIE),the ratios of 30th to 15th R R interval (R30/15),the response indices to Valsalva maneuver(VS Index) (P<0.01 or P<0.05).The results showed that the exercise of distance running can improve the FCANS of students.
