摘要
目的 探讨腹式呼吸对心算时心血管反应性有无影响。方法 30名A、B型人格大学生 ,随机分为实验组和控制组 ,实验组被试进行腹式呼吸后做心算 ,控制组不做腹式呼吸做心算 ,测量心率变异性及血压。结果 心算时 ,两组心率、血压显著上升 ,实验组腹式呼吸后舒张压显著下降 ;PNN50 4表现出显著的性别效应 ,组别与性别在最大心率 3、HFnu4和LF HF4上有显著的交互作用 ;人格因素在各项指标上无显著效应。结论 心算是一种有效的心理应激 ;女性腹式呼吸后交感神经活动降低 ,副交感神经活动增强 。
Objective To explore the influences of diaphragmatic abdominal respiration on reducing the stress response about mental arithmetic. Methods 15 type A and 15 type B college students were selected. Before mental aritnmetic, Experimental group received diaphragmatic abdominal respiration training, control group received no training Heart rate variability (HRV) and blood pressure were measured.Results During mental arithmetic,heart rate and blood increased significantly;There was a significant main effect on the index of PNN504 between males and females,There were significant interaction between sex and groups on the index of maximum heartrate3,Hfnu4,LF/HF4; No significant effect were found between TYPE A and TYPE B. Conclusions Mental arithmetic was an effective stress;Diaphragmatic abdominal respiration training had the greater effect on female than male.
