应激干预对不同行为类型大学生心率血压手指温度的影响

EFFECTS OF COPING ON HEART RATE, BLOOD PRESSURE, FINGER TEMPERATURE OF TYPE A AND B BEHAVIORAL UNDERGRADUATES

探讨应激干预对心率、血压、手指温度的影响及不同行为类型的差异。被试为河北师范大学本科生 72人(A、B型各 36人 ) ,应激干预为音乐放松、腹式呼吸和静坐休息 ,实验包括基线期 -干预期 -应激期 -恢复期四个阶段 ,在观看紧张性影片前进行应激前干预 ,记录被试的心率、血压、手指温度。结果发现 ,就缓解应激所产生的交感神经活动增强来说 ,音乐放松效果较好 ,腹式呼吸也明显优于自然休息 ;行为类型 (A、B)和应激干预大多表现出来交互作用 ;个体生理反应的性别差异与生理指标有关 ,基线值的性别差异较大时 ,男女生的生理数据不宜混合在一起 ,基线值相差不大时 ,可以用相对值 (如变化值或变化率 )进行统计处理。说明行为类型 (A、B)对于应激而言是一种微调变量 ,在自然休息状态或者低应激水平下作用更明显 ,应激水平较高时 ,行为类型的调节作用会显著降低 ;

To explore the effects of abdominal breathing and music relaxation on stress, and the differences due to personality. Ss were 72 undergraduates at Hebei Normal University. The subject' physical stress reactivity was reco-rded in four phases. The results showed: The effects of different stress coping method on stress were different, and music relaxation was better. The effect of abdominal breathing was higher than natural, but it was difficult to master abdominal breathing. The heart rate of type-A behavior was higher than that of type-B behavior in baseline phase. The same was in the stress phase, but the difference extent was lower than the baseline phase. The effects of medi-variable and stress coping method were complex, and most exhibited in mutual ways. The gender difference of individual physical reactivity varied in different physical index. This indicated: The behavior pattern was inching variable, and had effect in natural or low stress level. The effect of behavior pattern fell significantly in higher stress level. The different stress coping methods fit different patterns of individuals.
