腹式呼吸对女大学生应激状态下甲襞微循环的影响

Effects of Abdominal Breathing on Nailfold Microcirculation Among Female Students in Stress

目的探讨腹式呼吸对内、外向女大学生应激状态下甲襞微循环的影响,为开展相关研究提供参考。方法筛选典型的内向和外向女大学生各30名,随机分为实验组和对照组,实验组被试进行腹式呼吸训练后做心算;对照组不做腹式呼吸做心算,测量甲襞微循环。结果个体在应激状态下甲襞微循环状况变差,流速减慢,红细胞聚集增多;腹式呼吸能改善甲襞微循环管袢的清晰度、流速和红细胞聚集的情况。内向者在腹式呼吸时红细胞聚集小于外向者,在应激状态下红细胞聚集大于外向者。结论腹式呼吸对应激引起的微循环变差有一定的对抗作用,内向者的微循环变化更容易受应激水平的影响。

Objective To explore the effects of abdominal breathing on mierocirculation of female students in stress, and to provide reference for the related research. Methods Thirty female introverts were taken as experiment group, another thirty female extroverts were taken as control. Before mental arithmetic, experiment group trained diaphragmatic-abdominal respiration,while control group made mental arithmetic without diaphragmatic-ahdominal respiration, Nailfold microcirculation was measured. Results Nailfold microcirculation became poor,After abdominal breathing, the capillary loop＇s distinction increased significantly, the velocity of blood flow increased significantly.The aggregation of the red cell decreased significantly. The introverts＇ red cell aggression was lower than the extroverts＇ during abdominal breathing, but higher than the extroverts＇ in stress.Conclusion Abdominal breathing can influence microcirculation. Stress influence introverts＇ microcirculation greater than extroverts.
