Alterations with ageing in the responses of heart rate (HR), urinary excretion of free epinephrine (E) and norepinephrine (NE) and anxiety were investigated during mild mental stress. Forty-eight normal male volunteers were studied: in control conditions; when subjected to psychometric tests; and during recovery. Men in their seventies had lower baseline levels of HR, E and NE than men in their fifties. Several anxiety indices were positively correlated with E. HR and NE were positively correlated. During stress, mean HR and E levels increased in the two age groups by the same percentages. Mean HR and E levels returned to pre-stress values more slowly in the older age group.
在轻度精神应激期间，研究了心率（HR）、游离肾上腺素（E）和去甲肾上腺素（NE）的尿排泄量以及焦虑反应随年龄的变化。对48名正常男性志愿者进行了研究：在对照条件下；进行心理测试时；以及恢复期间。七十多岁的男性的HR、E和NE的基线水平低于五十多岁的男性。几个焦虑指标与E呈正相关。HR和NE呈正相关。在应激期间，两个年龄组的平均HR和E水平以相同的百分比增加。老年组的平均HR和E水平恢复到应激前值的速度较慢。
