摘要
目的:探讨健康男性性格特征与交感神经系统活性的关系。方法:采用A型行为问卷确定受试者性格特征,并将受试者分为A型行为组和非A型行为组。用握力试验激活交感神经系统。测定两组受试者握力试验前后血压和心率。结果:56名血压正常的健康男性入选。其中A型行为组22名,非A型行为组34名。两组受试者年龄、体重指数、基础血压和心率无显著性差异,具有可比性。握力试验中虽然A型行为组血压和心率增量高于非A型行为组,但是两组无显著性差异,P>0.05。结论:不同类型性格特征的健康男性中,负荷状态下交感神经活性或血流动力学反应相似。
Objective: To evaluate the relationship between behavior type and sympathetic activity in healthy males. Methods: Subjects were divided into tape A group and non - tape A group based on type A scores. We measured heart rate, blood pressure, and sympathetic nerve activity at rest and during handgrip test in 56 healthy males who were taking no medications. Results: 56 healthy males were entrolled in. 22 of them were in tape A group. The others were in non - tape A group. The clinical characteristics were similar between two groups. Although blood pressure and heart rate increased during handgrip test in tape A group, there were no significant differences between two groups. There were no significant differences in sympathetic or hemodynamic reactivity between two groups, P > 0.05. Conclusion: Sympathetic nerve and hemodynamic measurements during stress were not different in normal subjects with and without type A characteristics.
